Choosing a pool resurfacing company in South Carolina shouldn’t feel like a gamble. But for most homeowners, it does.
Every company’s website says roughly the same thing — experienced, professional, quality work. The problem is figuring out who actually delivers on that and who disappears after the check clears.
After working on pools across the Charleston Lowcountry, we’ve seen what happens when homeowners hire the wrong company. Coatings that peel within a year. Prep work that was skipped. Warranties that turn out to be worthless. And pools that need to be resurfaced again in half the time because someone cut corners on materials.
These 10 questions are designed to help you avoid those outcomes. Ask them to any company you’re considering — including us. The answers will tell you everything you need to know.
1. Do you specialize in resurfacing, or is it one of many services you offer?
This is the most important question on the list.
A general pool company that also does resurfacing is not the same as a company that focuses on resurfacing and coatings as its primary trade. General contractors often subcontract the finish work to someone else — which means the crew applying your coating may not be the people you vetted.
Companies that specialize in resurfacing invest in training, specific equipment, and material relationships that generalists don’t. They also see more failure patterns, which means they’re better at diagnosing problems before coating over them.
What a good answer sounds like: “Resurfacing and coatings are our core business. We do it ourselves — no subcontractors.”
2. What surface preparation do you do before applying the new finish?
Prep work is where most resurfacing jobs succeed or fail. A new coating applied over a poorly prepared surface will delaminate, blister, or crack — sometimes within months.
Proper preparation includes draining the pool (with dewatering in high-water-table areas common across coastal SC), stripping the old finish completely, repairing structural cracks or blisters, and sanding or blasting the substrate to create a clean bonding surface.
Red flag: A company that quotes the job without inspecting the pool in person. They can’t know what prep work is needed from a phone call or photo.
3. What coating system do you use, and why?
Not all pool finishes perform the same — especially in South Carolina’s climate. Salt air, sustained humidity, and intense UV break down porous finishes like plaster and paint far faster than national averages suggest.
Ask specifically what product they apply, whether it’s porous or non-porous, how it’s applied (troweled, sprayed, thermally fused), and what its expected lifespan is in a coastal environment. A good company will explain the trade-offs between different systems without dodging the question.
What to listen for: Technical specifics, not marketing buzzwords. If they can’t explain how the product bonds to the surface and why it performs in your climate, they may not understand it themselves.
4. Can I see examples of pools you’ve resurfaced in my area?
Before-and-after photos are a minimum. What you really want is evidence of work done in conditions similar to yours — same pool type, same region, and ideally projects completed 2–3+ years ago so you can see how the finish is holding up.
Any company that’s been working in the Charleston Lowcountry for more than a season should have a portfolio of local work. If they can’t show you completed projects nearby, ask why.
Bonus: Ask if you can speak with one or two previous customers directly. Legitimate companies welcome this.
5. Are you licensed, insured, and willing to provide proof?
South Carolina requires contractors to carry appropriate licensing and liability insurance. This protects you if something goes wrong — property damage, injury, or defective work.
Ask for a copy of their certificate of insurance and verify it’s current. If they hesitate, that tells you what you need to know.
Non-negotiable: General liability insurance, workers’ compensation coverage, and a South Carolina contractor’s license appropriate for the scope of work.
6. What does your warranty actually cover?
“We offer a warranty” means nothing without specifics. Ask for the warranty document in writing before you sign anything, and read what’s covered and what’s excluded.
Key questions about the warranty: Does it cover materials only, or materials and workmanship? What maintenance requirements must you follow to keep it valid? Is it transferable if you sell the home? What’s the claim process if something fails?
A strong warranty from a company that stands behind its work is one of the best indicators of quality. A vague promise without documentation is not a warranty — it’s a hope.
7. How do you handle draining on properties with a high water table?
This question is specific to South Carolina — and it separates local experts from out-of-area contractors.
Many areas across the Lowcountry have water tables that sit close to the surface, particularly near the coast, rivers, and marsh. Draining a pool — especially a fiberglass shell — without active dewatering in these zones creates a real risk of hydrostatic uplift. The ground water pushes against the empty shell and can crack or shift it permanently.
What you want to hear: A specific description of how they assess ground water conditions, whether they use dewatering wells, and how they monitor the pool during draining. If they’ve never heard of hydrostatic uplift, they haven’t worked on enough coastal SC pools.
8. How long will the project take, and when can I swim?
Timelines vary by coating system. Traditional plaster requires a 28-day cure period with careful daily water chemistry management before swimming. Thermo-polymer coatings cure on contact and allow swimming within 24–48 hours.
Know what you’re getting before work starts. If a company tells you the project takes 7–10 days, ask why. If they say you can swim the same day, ask how the curing process works and what that means for water chemistry at startup.
Good benchmark for polymer coatings: 1–2 working days for most residential pools, swim-ready within 24–48 hours.
9. What happens if you find damage underneath the old surface?
No honest company can guarantee the price won’t change once they strip the old finish and see what’s underneath. Subsurface cracks, delamination, osmotic blistering, and plumbing issues often only become visible after the old surface is removed.
The question isn’t whether this can happen — it’s how the company handles it. A professional company will stop, show you the damage, explain what repair is needed, and give you a clear cost before proceeding. A questionable company will either coat over it without telling you or hit you with an inflated surprise charge.
Ask directly: “If you find something unexpected, what’s your process for communicating and pricing the repair?”
10. Will you give me a written estimate that breaks out every cost?
A lump-sum quote with no line items makes it impossible to compare companies or understand what you’re paying for. Ask for an itemized estimate that separates draining, surface prep, structural repairs, coating application, fittings, and any additional work.
This also protects you from hidden costs. If something isn’t in the estimate, confirm in writing whether it’s included or excluded before work begins.
What a professional estimate includes: Scope of work, materials specified by name, timeline, payment terms, warranty terms, and what’s not included.
The Checklist: Use This Before You Hire
Before signing with any pool resurfacing company in South Carolina, confirm all ten:
- Specializes in resurfacing (not a generalist)
- Explains their prep process in detail
- Names and explains their coating system
- Shows local portfolio with aged examples
- Provides current license and insurance proof
- Gives warranty terms in writing before signing
- Describes their draining protocol for high water table
- Provides a clear timeline with swim-ready date
- Has a documented process for handling hidden damage
- Delivers an itemized, line-by-line written estimate
If a company checks all ten, you’re in good hands. If they can’t answer three or more, keep looking.

Frequently Asked Questions
What should I look for in a pool resurfacing company?
Look for a company that specializes in resurfacing (not a general pool contractor), uses named coating systems with documented performance data, provides a written warranty covering both materials and workmanship, carries current South Carolina licensing and insurance, and can show you local examples of work completed 2+ years ago. Avoid companies that quote without an in-person inspection or can’t explain their surface preparation process.
Is SC Pool Resurfacing certified?
Yes. SC Pool Resurfacing is a certified applicator of ecoFINISH® polymer coating systems, including aquaBRIGHT™ for concrete and gunite pools and polyFIBRO® for fiberglass pools. We carry full South Carolina licensing and liability insurance, and every project is backed by a 10-year limited warranty on materials and workmanship. You can learn more on our About Us page or contact us for documentation.
How do I know if a pool resurfacing company is legitimate?
Verify three things: current South Carolina contractor licensing, active liability insurance with workers’ compensation, and a portfolio of completed local projects with verifiable customer references. Check Google reviews for consistent feedback over time — not just a handful of recent five-star reviews. A legitimate company will also provide a written, itemized estimate and warranty terms before any work begins.
What questions should I ask before hiring pool resurfacing?
At minimum, ask what coating system they use and how it performs in your climate, what surface preparation they do before applying the finish, what their warranty covers specifically, how they handle draining in high-water-table areas, and what happens if they discover hidden damage during the project. These five questions alone will eliminate most unqualified contractors. For the full list, see our FAQ page or the 10 questions above.
