New Build Mastic in Polegate
New build mastic for Polegate, by sealant specialists with 20+ years’ experience. Rated 4.9 on Google from 180+ five-star reviews.
- Cracked sealant around new window and door frames

- Second-fix sealing on new plots
How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Open a window or run the fan after bathing
- Wait for the cure time before using a resealed shower
- Record problems with dated photos
- Check bath and shower seals every few months as the house settles
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers so moisture does not sit on the sealant.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
How we handle new build mastic in Polegate
Building dust is behind a lot of failed new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the sealant actually sticks instead of bonding to the dust. Common call-outs are for cracked sealant around new window and door frames and sealant applied over dusty or wet surfaces, on bathrooms & en suites, plot handovers and show homes.
For a new home in or near Polegate, it’s worth checking the sealant early. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.
Our work is backed for twelve months.

What the job involves on each surface
Windows and doors
On new builds, external frame sealant can be patchy. It’s resealed with an exterior sealant suited to the frame and wall.
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
For landlords and businesses
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together.
For anyone letting property in or around Polegate, jobs at different addresses can go on one quote. Send us the addresses and the work at each, and pictures by email help.

- Leaking shower tray seals in a new home

- Gaps between new skirting and floors
- Frame joints opening as the plaster dries

How the visit works
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and tidy away. Most jobs take anything from a few hours to several days, depending on the number of plots. Parking around Polegate is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- Each joint is checked for movement before we start.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know if you’ve seen damp or leaks
- Keep pets and children clear of the area while we work

Related advice
What happens if it’s left?
A quick bead over the top of the old sealant can look fine at first, but it can’t bond to what’s underneath. A lasting seal starts with removing the old one completely. In a smaller place like Polegate, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, phone 0345 464 0079 or send us an email for an honest opinion and a quote.

Should I wait before resealing?
For failed seals that let water through, the best time is now. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
Where do you work from?

Can you reseal over the builder’s sealant?
No. The old sealant is cut out fully, then clean and prime the joint, before resealing.
Can you work from my snagging list?
Yes. Snagging lists are a common starting point for us. We’ll go through the sealant items and agree what we will do.
Do you guarantee your work?
Yes. Each job is guaranteed for twelve months, wherever you are.
DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
