How we handle new build mastic in Thong
Building dust is behind a lot of failed new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the sealant actually sticks rather than sitting on a layer of grit. We are often asked to deal with cracked caulk along new skirting and smeared, uneven beads picked up at snagging, across plot handovers, bathrooms & en suites and show homes.
Around Thong, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
A one-year guarantee comes as standard.

Common questions in Thong
I let a flat near Sole Street station. Can you help?
Yes, we work for landlords and letting agents. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Do you cover Thong for new build mastic?
Yes, Thong is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job, and we will send you a clear quote.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
Do you work through snagging lists?
Yes. Send the list and a few photos of the sealant items. We’ll tell you if anything on it isn’t a sealant job.
Who should fix failed sealant in a new build?
Your builder, if you’re still in their snagging or warranty period. If that doesn’t work out, we are happy to quote with our 12-month guarantee.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Can you reseal over the builder’s sealant?
No. Over-sealing traps mould and water and soon fails. All the old sealant comes out before any work starts.
Do you do commercial work?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
The process
We keep the work tidy and contained to the joints we are treating. Expect the work to take anything from a few hours to several days, depending on the number of plots, and we explain the cure time before we leave. Somewhere as small as Thong, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each joint is checked for movement before we start.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Let us know about stairs, lifts or work at height
- Let us know about earlier repairs to the joints

Advice
What we’re called out for in Thong
Once people move in, baths and trays take weight and bed down. A bath sealed empty drops slightly when filled, straining the joint.
Common reasons people contact us include:
- Leaking shower tray seals in a new home
- Cracked caulk along new skirting
- Kitchen sealant that has pulled off the wall
- Second-fix sealing on new plots
In and around Thong, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Questions to ask before booking
- How long the guarantee is
- When the joint can take water or movement
- What happens if they find a problem under the old sealant
- Which sealant they’ll use, and why
What affects the cost of new build mastic
Your quote is based on your job. We look at:
- The number and length of the joints
- Whether there’s mould to deal with
- Which sealant suits the joint
- Working hours on commercial sites
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we will explain what it covers.
What to tell us for a quote
Photos by email are helpful but not essential. Please mention:
- Pictures of the joints, sent by email
- Where the job is, and your postcode
- How many joints, rooms or windows are involved
- Any previous sealing or DIY work
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we’ll talk you through what we’d do. Whenever you’re ready, phone 0345 464 0079 or drop us an email.
Why it’s worth doing now in Thong
A hairline gap at a skirting can wait, but a leaking seal cannot. Not sure whether yours can wait? You can phone 0345 464 0079 or drop us an email with a few pictures and we will tell you. Around Thong, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and agree the price before starting.

We’d rather tell you now than do work that won’t last, so these are the limits:
- Movement caused by a poorly fitted tray or bath
- Damaged fittings that need replacing
- Leaks from pipes, valves or wastes, which need a plumber
If in doubt, call 0345 464 0079 or send us an email and we will say what we think.

New build mastic around Thong
Thong is close to the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you’ve bought a new home near Sole Street station, the sealant around baths, showers and frames is worth checking in the first year or two.

Can I do it myself?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
