Get three contractors to look at the same pool and you’ll often get three numbers that don’t sit anywhere near each other. That’s not one company overcharging and two undercutting. A pool resurfacing quote isn’t a price for a fixed product — it’s a price for a specific job. The job changes depending on the pool’s size, its finish, and what’s actually under the old surface. Two quotes that both say “resurfacing” can be pricing genuinely different amounts of work.
Once you understand what drives the number, comparing quotes stops being guesswork.
A 10×5 metre pool has more than twice the surface area of a 6×4 metre one. You might assume the price should roughly double too. It doesn’t.
Some costs are fixed regardless of size. Setting up on site, moving equipment in, and protecting paving all take similar effort whether the pool is small or large. The material and labour that do scale — the marbelite plaster or the fibreglass resin and matting — go up with area. But the fixed portion doesn’t multiply the same way.
This is why a bigger pool often looks proportionally cheaper per square metre than a small one. It isn’t a discount. It’s the fixed costs spreading over more surface.
This is the biggest reason two quotes for the same pool diverge. A contractor who only looks at the pool from the deck, full of water, is quoting blind. Old marbelite hides spider cracks. Old fibreglass hides blisters that haven’t broken through.
A proper resurfacing quote follows a site inspection. Ideally, the contractor looks at the shell once it’s drained, not a number given over the phone. If the concrete underneath needs patching, or substrate has moved, that work gets added before any new finish goes down.
Skip that step at quote stage and you get a suspiciously low number. Then it becomes a change order once the crew is on site and sees the real condition. This is why two honest quotes for the “same” job can still differ. One contractor priced what they could see. The other priced what they expect to find, based on pool age and coping condition. The second number is usually closer to what you’ll actually pay.
The finish you choose changes both the price and what that price covers. Marbelite is a cement-and-marble-aggregate plaster, applied by hand and left to cure overnight. Most of its cost is labour — skilled hands mixing and troweling a consistent finish across the whole shell.
Fibreglass involves plastering the surface, letting it dry completely, then applying resin and a gelcoat top layer. More of that cost sits in material, because resin and gelcoat aren’t cheap inputs. On a standard 6×4 metre pool, re-marbelite runs around R18,000. Refibreglassing costs around R25,000. Both jobs take roughly three to five days on site. The time is similar. The price difference reflects what goes into the finish itself.
Finish
What drives the cost
Time on site (6×4m)
Marbelite
Skilled labour, hand application, overnight cure
3–5 days
Fibreglass
Resin, matting and gelcoat material, staged curing
3–5 days
Neither finish is the “wrong” choice. Neither quote is padded just because the numbers don’t match a competitor’s. They’re pricing two different sets of materials and two different skill sets.
Most jobs get one overall figure rather than a line-by-line breakdown. That’s normal and isn’t a sign someone’s hiding something. Minor adjustments — a different light colour, a change in sand grade — usually sit inside that overall price.
What you should ask, whatever the format, is what finish is specified and whether the quote followed an actual look at your pool. A single number from an inspection is worth more than an itemised one that didn’t. When one pool refinishing quote comes in noticeably lower than the others, the gap rarely reflects profit margin. It’s usually scope.
A cheaper resurfacing estimate often means the contractor hasn’t allowed for patching cracks in the substrate. It can mean plans for a thinner coat than the finish needs to last years, not months.
It can also mean older fittings and piping get reused rather than replaced, even where they’re due for renewal. None of that shows on the quote sheet. It shows eighteen months later, when the surface starts failing in the same places.
Before you set two numbers side by side, check that they answer the same question. Ask these four things:
Did the quote follow a site visit, or was it given over the phone?
Does it specify marbelite or fibreglass, or just say “resurfacing”?
Does it mention allowance for patching or substrate repair?
Who’s doing the work — the same team that quoted, or a subcontractor?
A quote that answers all four honestly is worth more than one that’s simply lower.
The cheapest quote isn’t always wrong, and the most expensive isn’t always right. What matters is whether the person who wrote it actually looked at your pool, named the finish, and priced for what they expect to find once the old surface comes off.
Trademen Pools has been building and resurfacing pools across Gauteng since 2013. We handle every job in-house with our own team, which means the people who quote your work are the people who do it. We’ll inspect your pool properly, specify marbelite or fibreglass based on your shell and budget, and give you an honest quote for pool resurfacing that accounts for what we expect to find.
We offer pool remarbeliting and refibreglass services with three to five-day timelines and warranties that back the work we do. No surprises, no hidden costs, no change orders because we didn’t look closely enough at the start.

Frequently asked questions
Why do pool resurfacing quotes vary so much?
Pool resurfacing quotes can differ significantly because each quote is for a specific job, not a fixed product. Factors like the pool’s size, the chosen finish (marbelite or fibreglass), and the condition of the underlying shell all influence the final price. Two quotes for the ‘same’ pool might be pricing genuinely different amounts of work.
How does pool size affect the resurfacing cost?
While you might expect the price to double for a pool twice the size, it doesn’t work that way. Some costs, like site setup and equipment protection, are fixed regardless of pool size. The materials and labor that do scale with area are only part of the total cost, so larger pools often appear proportionally cheaper per square metre because those fixed costs are spread over a greater surface.
What’s the biggest reason for differing resurfacing quotes?
The biggest reason for differing quotes is the condition of the pool’s shell beneath the old surface. A contractor who only looks at the pool from the deck without draining it is essentially quoting blind. Old marbelite can hide cracks, and old fibreglass can hide blisters. A proper quote requires an inspection of the drained shell to identify any necessary patching or substrate repairs, which adds to the cost.
What’s the difference in cost and process between Marbelite and Fibreglass finishes?
Marbelite is a cement-and-marble-aggregate plaster, with most of its cost attributed to skilled labor for hand application. Fibreglass involves plastering, drying, and then applying resin and a gelcoat top layer, making material costs a larger component. For a standard 6x4m pool, re-marbeliting costs around R18,000, while refibreglassing is about R25,000, even though both jobs take a similar amount of time on site.
What should I ask before comparing pool resurfacing estimates?
Before comparing estimates, you should ask: Did the quote follow a site visit or was it given over the phone? Does it specify marbelite or fibreglass, or just say ‘resurfacing’? Does it mention allowance for patching or substrate repair? And who is doing the work – the quoting team or a subcontractor? A quote that answers these questions honestly is more valuable than one that is simply lower.
Where do cheaper pool resurfacing quotes typically cut corners?
Cheaper resurfacing estimates often mean the contractor hasn’t accounted for patching cracks in the substrate, may apply a thinner coat of the finish than is needed for longevity, or might plan to reuse older fittings and piping that are due for replacement. These shortcuts aren’t visible on the quote but can lead to surface failures later.

Put one clear price next to the other two
Trademen Pools prices a remarbelite or refibreglass job as one overall price, with minor changes like a light or sand change included, so you can compare it line for line with the quotes you already hold. The team can start without a waiting list, and most resurfacing jobs take three to five days.
