New build mastic for homes and businesses in Litlington
We work in new homes and on new-build sites across Litlington. Whether it’s one en suite or a run of plots, the method is the same: cut out, clean, prime where needed and reseal neatly. We work on show homes, kitchens and skirting & floors, and common reasons people get in touch are kitchen sealant that has pulled off the wall and sealant applied over dusty or wet surfaces.
In a village or hamlet like Litlington, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
You get a 12-month guarantee, the same in Litlington as everywhere else we work.

Signs you need new build mastic in Litlington
Sealant is often one of the last jobs before handover. Joints are not always cleaned of dust or primed, and the sealant sits on grit instead of the surface.
Any of these means the joints need attention:
- Gaps opening as the house dries out and settles
- Leaking shower tray seals in a new home
- Smeared, uneven beads picked up at snagging
- Sealant that never bonded to the surface
In and around Litlington, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Questions to ask before you book
- How the joint is cleaned and prepared
- How much experience the applicator has
- How long the guarantee is
- When the joint can take water or movement
New build mastic in Litlington: local notes
Litlington is within about 3 miles of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. Rainfall in the South East is lower than in much 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 Berwick (Sussex) station, the sealant around baths, showers and frames is worth checking in the first year or two.
Litlington is about 3 miles north-east of Seaford, in East Sussex. From the centre of Litlington to the outskirts, new build mastic is available for homes and businesses alike. Across East Sussex, we cover 289 places, Litlington among them. You can also see our page for Brighton, about 13 miles away.

When it isn’t the sealant
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Leaks from pipes, valves or wastes, which need a plumber
- Deciding who is responsible under a builder’s warranty
- A tray or bath that is not properly supported, until it’s fixed
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think before booking.

- Kitchens
- Plot handovers
- Show homes
- Bathrooms & en suites
- Skirting & floors
- Windows & doors
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Open a window or run the fan after bathing
- Avoid running a DIY bead over the old one
- Don’t wait for the house to settle if water is getting through
- Watch for new gaps as the house dries out
Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it.
Report failed sealant to the builder while you are in the snagging period. After that, putting it right may fall to you so report it promptly.

How the job changes by surface
Kitchens
Worktops in new homes can move slightly as the house dries, opening gaps behind the upstand. We reseal them with a flexible sealant.
Show homes
Tired or marked sealant in a show home can be renewed. The old bead comes out and a clean new one goes in.
Should I try it myself first?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
What we do, step by step
Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for most snagging lists, longer for a run of plots. In a small place like Litlington, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Let us know about stairs, lifts or work at height
- Let us know if you’ve seen damp or leaks

Is Litlington within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is it messy?
No. We protect the surfaces around the joints, and we tidy up before we go.
Can you do plot mastic on a new development?
Yes. Plot mastic and second-fix sealing for developers is part of our work. Send us the plot schedule and we’ll quote.
Will the old sealant be removed?
Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.
Do you guarantee your work?
Yes. Each job is guaranteed for twelve months, wherever you are.
Why has my new-build shower seal failed already?
A new house dries and settles for a year or two, and sealant is often rushed onto dusty, unprimed surfaces. Both lead to early failure.
Do you hold any approvals?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
