Buying an inground pool should be straightforward. You know what you want. You find someone to build it. You pay a fair price and get what you ordered.
In reality, the pool buying process is one of the most opaque major purchase experiences in residential construction. Pricing is deliberately vague at the top of the funnel. Proposals range from highly detailed to nearly unreadable. The same project scope can produce quotes that differ by 40% between builders. Timelines are routinely understated. And the mistakes that are most expensive to correct — wrong builder, wrong design, wrong scope expectations — are made at the beginning of the process when homeowners have the least information.
The opacity is partly cultural — the pool industry has historically relied on high-pressure sales environments where the goal was to get a commitment before the homeowner had time to research. That model is changing, but slowly. The homeowners who navigate this process best are the ones who arrive informed enough to recognize vague answers for what they are.
Scott Payne Custom Pools was founded in 2014 by a builder with 25+ years of personal industry experience who holds certification from the International Watershape Institute (IWI). This guide reflects what we see homeowners get right — and get wrong — in real buying conversations, on real projects, in real municipalities across PA and NJ.
Clarifying Your Vision and Budget
The most productive thing a homeowner can do before talking to any builder is get genuinely clear on two things: what they want the pool and outdoor environment to do for their life, and what they are realistically able and willing to invest.
Stage 1: Clarifying Your Vision and Budget
What Do You Actually Want the Pool to Do?
Not "I want a pool." That is not a vision. That is a category. The vision is the specifics: Is this primarily for children's play, family swimming, fitness laps, adult entertaining, or some combination? How often do you realistically expect to use it? Who uses it most and what does that use look like? Is the pool the centerpiece of a broader outdoor living transformation, or is the pool the primary investment with minimal surrounding environment planned?
These questions are worth sitting with seriously before any design conversation begins. The answers shape every design decision that follows. The most common design regret in pool ownership is not that the pool was poorly built. It is that it was designed for the wrong purpose — or designed without a clear purpose at all.
Establishing a Realistic Budget Range
A realistic budget range for a custom inground pool in the Philadelphia suburbs and Lehigh Valley starts in the mid-$70,000s for a small, straightforward design on an accessible site with minimal patio. Most homeowners planning a well-designed pool with a functional patio and quality equipment are working in the $82,000–$110,000 range. Pool-plus-spa-plus-outdoor-living projects typically start around $125,000. Full estate-level backyard transformations represent $250,000–$500,000+ investments.
Budget conversations make people uncomfortable. But a homeowner who avoids the budget conversation until they have received proposals is setting up a very specific kind of frustration: falling in love with a design that cannot be built within their actual means, or receiving accurate proposals that feel deceptive because they anchor to a number that was never realistic.
Understanding Pool Types
Before you talk to builders, understand the three pool construction types — gunite, fiberglass, and vinyl — at a structural level. The differences are more fundamental than most homeowners realize.
Stage 2: Understanding Pool Types
Gunite / Concrete Pools are constructed entirely on your property. A steel rebar framework is formed to the pool's exact design dimensions — shape, depth, features, steps, benches, spa, and any custom elements. Concrete is then applied pneumatically. The defining characteristic is that every dimension is determined during design, not by a manufacturer. The pool can be any shape, any size, any depth profile. This flexibility comes with corresponding complexity — more trades, more phases, more time, and more skill.
Fiberglass Pools are manufactured in a factory as a single molded shell and set into an excavated hole using a crane. The defining characteristic is consistency and predictability. The constraint is equally fundamental: you choose from shapes and sizes that exist in a manufacturer's catalog. You cannot specify a custom geometry or a shape that responds to your specific property dimensions.
Vinyl Liner Pools use a structural frame with a replaceable vinyl liner as the interior surface. They offer the lowest upfront cost among inground pool types. The liner will need to be replaced periodically — typically every 8–15 years at a cost of $4,000–$10,000. This ongoing replacement cost must be factored into any honest total cost of ownership comparison.
The most productive question is not which pool type is best. It is which pool type fits your specific situation — your site, your design vision, your timeline, your budget, and your long-term ownership expectations. Scott Payne Custom Pools specializes exclusively in custom gunite construction. For a full comparison, see our Pool Types Guide.
Researching and Selecting a Builder
Builder selection is the single most consequential decision in the pool buying process. The quality of the finished project is determined more by the builder than by any other variable.
Stage 3: Researching and Selecting a Builder
Most homeowners underinvest in builder research. They get two or three proposals, compare the numbers, and choose based primarily on price. This approach selects against quality. The builders who compete most aggressively on price are frequently the ones who exclude scope, plan for change orders, and manage projects loosely.
Where to Start Your Research
- Portfolio review — Look at completed projects, not just renderings. Renderings show what a builder imagines. Completed projects show what they actually deliver.
- References — Ask for references from projects similar to yours in scope and market. Call them. Ask specifically: did the project come in on budget, on timeline, and on scope?
- Credentials — Verify license and insurance. IWI certification from the International Watershape Institute reflects advanced training in design, hydraulics, and construction standards.
- Online presence and reviews — Look for patterns, not outliers. A builder with 40 reviews averaging 4.8 stars with a consistent theme of strong communication is providing more useful information than a builder with 5 perfect reviews.
- The conversation quality — Do they ask thorough questions about your site, your goals, and your budget? Or do they immediately pivot to showing you designs and talking about price? Builders who lead with education tend to manage projects better than builders who lead with sales.
Questions to Ask Every Builder
| Question | What the Answer Reveals |
|---|---|
| How do you handle change orders? | Process discipline — documented changes prevent disputes |
| Can you provide a certificate of insurance? | Financial stability and professionalism |
| Who pulls the permits and who pays the fees? | Experience with local municipalities |
| What does your payment schedule look like? | Large upfront deposits transfer risk to the homeowner |
| Can I speak with three recent clients? | Confidence in their track record |
| What is your warranty coverage? | Commitment to standing behind their work |
| How do you communicate during construction? | Whether you'll be informed or left to wonder |
Red Flags: What to Watch for When Evaluating Builders
- Pressure to sign before you have had time to review the proposal carefully
- Reluctance to provide references from recent, comparable projects
- Vague or verbal commitments that are not reflected in the written proposal
- Payment schedules requiring large deposits before any work begins
- No clear change order process described in the contract
- Inability or unwillingness to provide a certificate of insurance on request
- Timelines that describe only the construction phase, not the full project journey
- Proposals that do not include an explicit exclusions list
Reading and Evaluating Proposals
A pool proposal is a legal document and a project management tool. The way a builder writes their proposal reveals how they think about their projects and their clients.
Stage 4: Reading and Evaluating Proposals
What a Complete Proposal Includes
- Detailed scope with specific dimensions and materials
- Patio scope in square footage and material type
- Equipment by specific make and model
- Explicit exclusions list
- Permit responsibilities clearly stated
- Documented change order process
- Payment schedule tied to milestones
- Written warranty terms
- Realistic project timeline
Warning Signs in a Proposal
- "Custom pool" without dimensions or specs
- Patio described as "included" without square footage
- "Premium equipment" without brand or model
- No exclusions list at all
- Permits described as "handled" without specifics
- No change order language
- Large upfront deposit before work begins
- Verbal warranty promises not in writing
- "8–12 weeks" with no permitting timeline
How to Compare Proposals Accurately
The most common comparison mistake is price comparison between proposals that do not include the same scope. A $95,000 proposal that includes 800 square feet of natural stone patio, a spa, and full automation is not comparable to an $85,000 proposal that includes a minimal concrete deck, no spa, and standard equipment. The $85,000 proposal is not cheaper. It is incomplete.
When proposals are genuinely scope-comparable, price differences become meaningful. A 5–10% difference on comparable scope is within normal range. A 20–30% difference requires explanation — either something is excluded, something is underspecified, or the lower-priced builder has a different approach to how the difference will be recovered.
Negotiating a Pool Proposal
Negotiation in pool projects is more productive when focused on scope than on price. Common scope adjustments that reduce cost without sacrificing essential quality: simplifying pool geometry, choosing a pebble aggregate finish instead of glass tile, selecting standard coping instead of custom stone, choosing a smaller spa footprint, or phasing outdoor living elements into a later project.
Permitting, Pre-Construction, and What to Expect
The pre-construction phase is the one that surprises homeowners most. Everything has been decided, the deposit has been paid — and then weeks pass and nothing visible happens. This is normal.
Stage 5: Permitting, Pre-Construction, and What to Expect
Inground pool construction requires permits across the entire PA and NJ service area. In Pennsylvania, permits are issued at the township or borough level. In New Jersey, they are issued under the statewide NJ Uniform Construction Code framework through the municipal construction office.
The time between permit submission and approval varies significantly. In straightforward PA townships, 2–3 weeks is achievable on a complete submission. In Lower Merion Township or municipalities with detailed review processes, 6–10 weeks is realistic. In NJ, 3–6 weeks is typical for complete submissions. These are not failures. They are the realities of regulated residential construction.
What You Can Do During This Phase
- Make your remaining selections. Interior finish color, coping material, tile selection, outdoor living specifications, equipment upgrades — all of these need to be decided before construction begins. Defer them and they become change orders.
- Arrange financing. Home equity loans, HELOCs, and pool-specific financing products all have their own approval timelines. Start the financing process before the permit is approved.
- Communicate with your HOA if applicable. HOA review should be initiated concurrently with the municipal permit application, not sequentially after it.
Active Construction Through Completion
The active construction phase is the most visible and emotionally charged part of the project. Progress is measurable. And the inconveniences are real. Knowing what to expect makes the experience significantly better.
Stage 6: Active Construction Through Completion
Construction phases in a custom gunite pool project follow a defined sequence: excavation, steel and rebar framework, gunite application and curing, plumbing and electrical rough-in, tile and coping, hardscape and patio, equipment installation, interior finish application, and startup. Each phase has dependencies. Progress is not always linear.
Gaps in visible activity are normal and expected. A 5–7 day gap after gunite application is the curing period. A gap before hardscape begins is typically trade coordination and material staging. Homeowners who understand this context experience construction very differently from those who interpret every quiet day as a problem.
How to Communicate During Construction
Asking your builder for a weekly update on what happened that week and what is planned for the coming week is a reasonable request. Being reachable for decision requests within 24 hours is a reasonable reciprocal commitment. When something concerns you, say so directly and promptly. A concern addressed at week two of construction is a conversation. The same concern raised at week ten is a dispute.
The Punch List and Completion
Do not release final payment until the punch list is complete. This is standard practice and every legitimate builder expects it. Final payment is your leverage to ensure completion. Use it appropriately.
Startup and Learning Your Pool
The startup period — approximately the first 28–30 days after interior finish application — requires specific chemistry management to protect the new surface. Your builder should manage this process and teach you to maintain it. Take the homeowner orientation seriously. These things are taught once well or learned slowly through expensive mistakes.
The Most Common Pool Buying Mistakes
Starting with price instead of vision
The homeowner who asks "how much does a pool cost" before they have defined what they want is setting themselves up for a frustrating comparison process. Define the vision first. Price follows from scope.
Choosing the lowest bid
The lowest bid is almost never the lowest total cost. The proposal that excludes scope, underestimates site conditions, or plans to recover margin through change orders will cost more than a complete proposal at a higher starting price.
Rushing the design phase
Design is the cheapest time to make decisions. Changes during construction are expensive. Changes after construction are very expensive. Time invested in thorough design is time that prevents change orders.
Underbudgeting for the outdoor environment
The pool is the centerpiece. The patio, outdoor kitchen, lighting, and landscaping are the environment. Most homeowners budget carefully for the pool and then discover that the outdoor environment they actually want costs as much or more.
Not checking references
Portfolio photography is a marketing tool. References are evidence. Calling three recent clients and asking specific questions about budget, timeline, and communication takes 30 minutes and can save months of problems.
Deferring selections until construction
Every decision deferred to construction is a potential delay. Interior finish selection, coping material, equipment upgrades, and outdoor living specifications all have lead times and construction sequence dependencies. Make them during permitting.
What Your Pool Contract Should Include
- Complete scope description with specifications — not just "custom pool" but full dimensions, materials, and feature list
- Explicit list of what is excluded
- Equipment specifications by make and model
- Patio and hardscape scope stated in square footage and material
- Permit responsibilities — who applies, who pays fees, who manages revisions
- Change order process — how changes are documented, approved, and priced
- Payment schedule tied to construction milestones, not calendar dates
- Project timeline with specific start estimate and expected completion range
- Warranty terms — structure, equipment, and workmanship, stated specifically
- Lien waiver provisions
- Dispute resolution process
How Scott Payne Custom Pools Approaches the Buying Process
This section exists not to sell you on one builder but to show you what a buying process grounded in education and transparency actually looks like in practice — so you know what to look for in any builder conversation.
At Scott Payne Custom Pools, every project begins with a real conversation about goals, property, and budget — not with a design presentation or a price discussion. Design does not begin until the site has been evaluated and the homeowner's vision is clearly understood. No construction begins until the design is approved and the permit is in hand. Change orders are documented and approved in writing before any changes are executed. The punch list is complete before final payment is accepted.
This is not a unique or proprietary approach. It is what disciplined project management looks like in residential construction. The reason it is worth describing explicitly is that not every builder operates this way — and knowing what good looks like helps homeowners recognize it.
Scott brings 25+ years of personal industry experience to every project and holds IWI certification from the International Watershape Institute. Scott Payne Custom Pools was founded in 2014 and serves homeowners across nine counties in southeastern PA and western NJ. If a conversation about your specific property and goals is useful, that option is always available.
