You bought a home with a pool in McKinney, Allen, or somewhere else in Collin County, and that pool is showing its age. Maybe it has stained plaster, tired tile, old equipment, and a deck that has seen better days. Or you have lived in your home for years and your existing pool no longer fits how your family uses it. Now you are staring down a real question: do you renovate what you have, or tear it out and start fresh?
This is not a simple question, and the honest answer is that it depends on a handful of factors that most contractors will not tell you upfront. In this guide, we are going to walk through every angle of that decision, including structural conditions, real cost ranges in the DFW market, what renovation can and cannot change, and a simple framework to help you arrive at the right answer for your specific situation.
What Pool Renovation Actually Covers
The word "renovation" covers a wide range of work, and understanding the scope helps you set realistic expectations. Here is what a renovation can address:
- Resurfacing: Replacing the interior plaster, pebble, or quartz finish. This is the most common renovation scope and dramatically refreshes the look and feel of the water. See our guide to pool resurfacing options in Collin County for a full breakdown of material choices.
- Tile and coping: Swapping out the waterline tile and the coping (the cap stone or material along the pool edge) updates the visual style of the pool without touching the shell.
- Deck work: Resurfacing, expanding, or replacing the surrounding deck with stamped concrete, travertine, or other materials.
- Equipment replacement: Upgrading your pump to a variable-speed model, replacing the filter, installing a new heater, adding automation, or converting to a salt system.
- Water features: Adding a waterfall, scupper, deck jets, or a sheer descent to an existing pool is absolutely possible through renovation.
- Lighting: Replacing old incandescent fixtures with color LED lighting is a popular renovation upgrade.
- Adding a sun shelf: A tanning ledge can be added to most existing pools, though it typically requires cutting into the existing shell and costs more than building one in from scratch.
- Adding an attached spa: In some cases a spillover spa can be added adjacent to an existing pool. Feasibility depends on the structural layout and plumbing of the current pool.

What Renovation Cannot Change
This is the part that matters most for your decision. Renovation has real limits:
- Pool shape: You cannot meaningfully change the shape of an existing gunite pool through renovation. The structural shell defines the shape permanently.
- Pool size: You can make a pool slightly larger by cutting into the shell and adding deck area in some configurations, but you cannot make a small pool into a large pool.
- Location in the yard: If your pool is in the wrong spot relative to your home, patio, or yard layout, renovation cannot move it. Only a rebuild can fix placement.
- Depth configuration: Altering the deep end or changing the overall depth profile of the pool is not practical through renovation.
- Fundamental structural problems: A severely cracked shell, failed plumbing buried under a deck, or compromised bond beam requires either a very expensive structural repair or a full replacement.
What a New Custom Build Gives You
Starting from scratch is a bigger investment, but it comes with real advantages that renovation simply cannot provide:
- Unlimited design freedom: Shape, size, depth, placement, every feature from day one. You design around your yard and your family, not around whatever the previous owner chose in 1998.
- Correct sizing: Many older pools in DFW neighborhoods were built to a standard "builder" spec that may not match how you actually use a pool. A new build can be sized precisely for your lifestyle.
- Optimal placement: You can choose sun exposure, proximity to the house, relationship to outdoor living areas, and flow of foot traffic from scratch.
- Modern equipment from day one: Variable-speed pump, high-efficiency filter, LED lighting, salt system, automation, and potentially a heat pump or solar heater, all new, all under warranty, all sized correctly for the pool you are building.
- Full warranty coverage: A new gunite pool carries comprehensive warranties on the shell, the finish, and all equipment. With a renovation, you are still working around an existing structure of unknown long-term condition.
- Integration with outdoor living: Planning a pool, spa, deck, outdoor kitchen, and landscaping all at once produces a more cohesive result than adding elements around an existing pool over time.
If you want to understand what a new build will actually cost, our detailed breakdown of what a new custom pool costs in McKinney covers the 2026 market clearly.
Real Cost Comparison in the DFW Market
Let us talk numbers, because this is where many homeowners are surprised. The assumption is that renovation is always cheaper than rebuilding. That is often true, but not always, especially once you factor in structural issues.
Renovation Cost Ranges
In the DFW and Collin County market in 2026, typical pool renovation projects fall into these ranges:
- Basic resurfacing plus tile: $12,000 to $22,000
- Mid-scope renovation (resurfacing, tile, coping, new deck, equipment upgrade): $25,000 to $45,000
- Full renovation with feature additions (everything above plus water features, sun shelf, spa, LED lighting, automation): $45,000 to $70,000
Structural repairs, if needed, are priced separately and can add $10,000 to $30,000 or more depending on the extent of the damage. For a comprehensive look at what drives these numbers, see our guide to pool renovation costs in McKinney.
New Build Cost Ranges
A new custom gunite pool in the North Texas market in 2026 typically costs:
- Entry-level custom pool (simple shape, standard finishes, basic equipment): $60,000 to $80,000
- Mid-range custom pool (freeform shape, upgraded finish, spa, sun shelf, LED lighting, automation): $90,000 to $130,000
- Premium pool and outdoor living package: $150,000 and up
Where the Costs Start to Overlap
Here is the key insight: a full renovation with structural repairs plus feature additions can easily reach $60,000 to $80,000. That is the entry point for a new custom build. When a renovation quote climbs into that range, the calculation changes. You are spending close to new-build money to fix and upgrade an existing pool that may still have an aging shell, old plumbing behind the walls, and a layout that was never quite right for your yard.
At that crossover point, a new build deserves serious consideration, because you get a full warranty, optimal placement, complete design freedom, and a pool designed around your actual life rather than someone else's.
Structural Condition Is Everything
The single most important factor in the renovation versus rebuild decision is the structural condition of the existing pool shell. A pool with solid bones is an excellent renovation candidate. A pool with significant structural problems is a different conversation entirely.
What Good Structural Condition Looks Like
A pool that is a good renovation candidate typically has:
- A sound gunite or concrete shell with no major cracks running through the structural layer
- Properly functioning plumbing that holds pressure
- A solid bond beam (the structural top edge of the pool)
- No significant ground movement or settlement under the shell
- Surface crazing or staining only (surface-level deterioration, not structural)
Surface crazing, those fine spiderweb cracks you see in older plaster, is cosmetic and normal. It does not indicate structural failure. It is exactly the kind of thing resurfacing fixes completely.
What Structural Problems Look Like
Watch for these warning signs that suggest deeper issues:
- Cracks that run through the full shell thickness: These allow water to escape and ground water to enter. They require structural repair before any cosmetic work.
- Settlement or shifting: If sections of the pool have moved relative to each other, there may be soil instability that needs to be addressed before any renovation makes sense.
- Persistent water loss: Losing more than a quarter inch per day (accounting for evaporation) suggests a leak. Leaks can be in the shell, the plumbing, or the fittings. Old pools with galvanized fittings that have corroded are especially vulnerable.
- Failed bond beam: A compromised bond beam can allow the entire top edge of the pool to shift, which is a serious and expensive structural problem.
Getting an Honest Structural Assessment
Before you commit to either path, get a proper structural assessment. Here is what that means in practice:
- Ask the contractor to specifically evaluate the shell, bond beam, and plumbing, not just give you a renovation quote.
- Have a pressure test done on the plumbing lines to check for leaks before any work begins.
- Ask directly: "If we find structural problems during the work, what could that add to the cost?"
- Get at least two opinions. A contractor who only does renovations has an incentive to call every pool a renovation candidate. A contractor who does both renovations and new builds can give you a more balanced view.
Our pool repair team assesses pool conditions honestly because we do both renovation and new construction. We will tell you plainly what the structure can support and what the risks are if you proceed with renovation on a compromised shell.
Age of the Pool: A Useful (But Not Perfect) Guide
The age of a pool is a useful starting point for the renovation versus rebuild conversation, though it is not the whole story.
10 to 15 Year Old Pools
This is the sweet spot for renovation. The shell is typically still structurally sound. The plumbing, while aging, is usually PVC and still in reasonable condition. The pool was likely built with reasonably modern standards. The main issues are cosmetic and equipment-related: tired plaster, dated tile, single-speed pump, old filter. A renovation in this range is almost always the right financial choice, provided the structural inspection comes back clean.
15 to 25 Year Old Pools
This is the range where the answer is genuinely uncertain and where structural inspection matters most. Some pools in this age range are in excellent structural condition and are outstanding renovation candidates. Others have accumulated problems that make renovation riskier. The structural assessment drives the decision here.
25 to 30+ Year Old Pools
Older pools in the DFW area may have galvanized fittings that have corroded, undersized plumbing that cannot support modern equipment, plumbing configurations that are no longer accessible, and shells that have experienced multiple decades of Texas heat and ground movement. These pools can still be renovated, but the scope of work is often broader and the unknowns are greater. When a 30-year-old pool needs full structural repair, full plumbing replacement, new equipment, new surface, new deck, new tile, and new coping, the math often starts to favor a rebuild.
Location and Layout: The Factor Renovation Cannot Fix
Here is a scenario that plays out regularly in North Texas neighborhoods: a family buys a home with a pool positioned in a corner of the yard, shaded most of the afternoon, too small for a family of five, and with a deck that makes the flow from the back door awkward. The pool itself is structurally fine.
In this case, renovation can make that pool look great. But no amount of renovation can move it, resize it significantly, or fix the layout problem. The family will spend $40,000 renovating a pool they still do not love because the fundamental design does not fit their yard or their life.
Before committing to renovation, ask yourself honestly:
- Is the pool in the right spot in the yard?
- Is it the right size for how we actually use it?
- Does the layout work with our house and outdoor living area?
- Are we okay with the pool shape, or do we wish it were fundamentally different?
If the honest answers are no, renovation is solving the wrong problem. A rebuild gives you the opportunity to design from the yard outward and get the layout right.
Feature Limitations of Renovation
Some features are more practical to build into a new pool than to add to an existing one. Understanding these limitations helps you weigh the value of each path:
Sun Shelves (Tanning Ledges)
Adding a sun shelf to an existing pool requires cutting into the existing shell, forming a new section, and integrating it structurally. It is absolutely possible, but it costs more than building one in from the start, and the result can sometimes look like an addition rather than an original feature. If a sun shelf is a high priority, it is worth factoring that into your renovation versus rebuild comparison.
Attached Spas
Adding a spa connected to an existing pool is possible in some configurations. The plumbing, pad, and shell work required depend heavily on the existing pool's layout. In some cases the added cost is reasonable. In others, the constraints of the existing plumbing make it more expensive than anticipated. A standalone portable spa may sometimes be a more cost-effective solution if a full in-ground spa is not in the renovation budget.
Changing Pool Shape
This is not a realistic renovation option for a gunite pool. The shell is a permanent structure. If the shape matters to you, a new build is the only path.
Water Features
Waterfalls, deck jets, sheer descents, and bubblers can all be added to existing pools through renovation. This is one area where renovation performs well, giving you the ability to meaningfully upgrade the sensory experience of the pool without a full rebuild.
Timeline Comparison
Timeline matters for DFW homeowners, especially if you are trying to hit summer swim season or a specific milestone.
- Pool renovation: Typically 2 to 4 weeks of active construction, depending on scope. The pool is out of service during that time, but yard disruption is minimal. Most homeowners can plan around this window.
- New pool construction: A full new gunite pool in the McKinney area takes 10 to 14 weeks from groundbreaking to swim-ready. Yard disruption is significant during this period, with heavy equipment, excavation, concrete work, and subcontractor schedules all in play.
If you need a pool ready for summer and you are making this decision in April, renovation is likely the only feasible path on the calendar. A new build started in April is unlikely to be swim-ready before late summer in most cases. If you are planning ahead from the fall, a new build's timeline is entirely workable.
Permit Implications in McKinney and DFW
Both renovation and new construction require permits in McKinney and throughout Collin County. Neither path skips the permit process.
However, new pool construction requires significantly more extensive permitting: structural engineering review, setback compliance, barrier and fencing requirements, and inspections at multiple stages of construction. This is all standard and manageable, but it does add to the timeline and to the administrative work involved.
Renovation permits are typically less complex, focused primarily on the scope of work being done. A reputable contractor handles the permitting process on your behalf in either case.
Our ongoing pool maintenance clients in McKinney often come to us for renovation assessments when their pools reach the 12 to 15 year mark, and we handle the full permit process as part of the renovation scope.
How to Get an Honest Assessment From a Contractor
This part is worth spending a few minutes on, because it can save you from making a very expensive mistake in either direction.
Questions to Ask Any Contractor
- "What is the structural condition of this shell, specifically?"
- "Will you pressure test the plumbing before giving me a final quote?"
- "What are the risks if we find additional problems once work begins?"
- "Do you handle both renovation and new construction?" (A contractor who only does one or the other has an inherent bias.)
- "What would a new build in this yard look like and cost compared to what you are proposing for renovation?"
- "What are the limits of what renovation can do here, specifically for this pool?"
Why Two Opinions Matter
For any renovation project over $20,000 or any new build, get a second opinion. Not because contractors are dishonest, but because they bring different perspectives, different experiences with similar pools, and different cost structures. Two competitive quotes also give you real leverage and real clarity on what is actually included.
Be wary of any contractor who pushes you strongly in one direction without walking you through the structural evaluation. A professional who respects your budget and your situation will help you understand both paths clearly before you decide.
Decision Framework: Questions to Help You Choose
Work through these questions honestly. The answers will point you in the right direction most of the time:
- Is the pool in the right location in the yard? If no, consider a rebuild. Renovation cannot fix placement.
- Is the pool the right size and shape for how you use it? If no, consider a rebuild. Renovation cannot fundamentally change either.
- What did the structural inspection reveal? Clean structure is a strong signal for renovation. Significant structural issues shift the math toward rebuild.
- How old is the pool and what is the plumbing condition? A pool under 20 years with PVC plumbing in good condition is a strong renovation candidate. A pool over 25 years with aging or compromised plumbing deserves a careful cost comparison.
- What is the full renovation cost estimate, including any structural work? If the full renovation quote is approaching $60,000 to $70,000, run a new build comparison before committing.
- What features do you want? If you want features that renovation cannot deliver (significant size increase, shape change, relocation, complete redesign of the pool area), a rebuild is the answer.
- What is your timeline? If you need the pool ready in 4 to 6 weeks, renovation is likely the only option that fits.
- What matters more, lower immediate cost or getting exactly what you want? There is no wrong answer, but being clear on this question makes the decision easier.
If you answered "renovation is the right fit" to most of those questions, move forward with confidence. Renovation is a proven, cost-effective way to restore a structurally sound pool. If the answers pushed you toward rebuild, that is also the right path for a meaningful number of homeowners, especially those who bought an older home in Collin County and inherited a pool that was never quite right for the yard.
Frequently Asked Questions
How long does a pool renovation take in McKinney, TX?
Most renovation projects in the McKinney and Collin County area take between two and four weeks of active work, depending on scope. A simple resurfacing may be done in less than two weeks. A full renovation with new deck, tile, coping, equipment, and water features can take four weeks or more. You will be without use of the pool during this period, but yard disruption is minimal compared to a new build.
Can I add a spa to my existing pool during renovation?
In many cases, yes. Adding an attached in-ground spa to an existing pool requires structural work and plumbing modifications, and the feasibility depends on the layout of your current pool. A site assessment will tell you what is possible. In some configurations the cost of adding a spa to an existing pool is close to the cost of building one integrated into a new pool.
I see small cracks in my pool plaster. Is that structural?
Fine surface crazing (a network of small cracks on the plaster surface) is cosmetic and extremely common in older pools. It does not indicate structural damage. It is one of the primary reasons pools are resurfaced and is completely resolved by applying new plaster, pebble, or quartz finish. Cracks that run through the full shell thickness, are wider than a hairline, or are accompanied by water loss are a different matter and need structural evaluation.
How do I know if my pool has a leak vs. normal evaporation?
The bucket test is the standard method. Fill a bucket with pool water and place it on a pool step so it is partially submerged. Mark the water level inside and outside the bucket. After 24 hours, compare the two. If the pool lost more water than the bucket (which accounts for evaporation), you likely have a leak. Losing more than a quarter inch per day after accounting for evaporation is a signal to have the plumbing and shell evaluated before proceeding with renovation.
Do I really need permits for pool renovation in McKinney?
Yes. The City of McKinney requires permits for significant pool work. A reputable contractor will handle the permit application and inspection scheduling as part of the project. Unpermitted work can create problems when you sell the home and may not be covered under any workmanship warranty. Always confirm that your contractor is pulling the appropriate permits.
Can I make my pool larger during renovation?
In a limited sense, minor extensions to a gunite pool shell are sometimes possible, but this is not a cost-effective way to meaningfully increase pool size. The structural and plumbing complexity of cutting into and extending an existing shell is significant. If pool size is a primary concern, a new build is the more practical and cost-effective path.
What is the best age to renovate a pool?
Pools typically need their first resurfacing between 10 and 15 years. The best time to do a broader renovation is when the plaster is failing, the equipment is aging, and you want to update the aesthetic, usually in that same 10 to 20 year window. Acting before the pool reaches the point of structural problems gives you the most renovation flexibility and the best cost outcome.
