About our new build mastic in Roffey
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. In both, preparation makes the difference, because that’s what rushed new-build sealant generally lacks. We work on skirting & floors, kitchens and bathrooms & en suites, and the jobs we see most are gaps between new skirting and floors and gaps behind new kitchen upstands.
Where new homes go up in smaller places like Roffey, it’s often a small development or a single plot. Each still needs its sealant and floor joints finished properly from day one.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Leave it or put it right?
The builder is usually the first port of call while the snagging or warranty period runs. If it keeps failing or isn’t dealt with, we can reseal it properly. In an older home around Roffey, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

What sealant work cannot fix
A few problems are outside what sealant work can do:
- Baths and trays that move too much for sealant to cope with
- Deciding who is responsible under a builder’s warranty
- Leaking fittings rather than failed sealant
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think.

How the job changes by surface
Skirting and floors
As timber and screed dry, skirting and floors shift. We use a flexible product rather than caulk.
Show homes
Show homes need sealant that looks right from day one. Every bead is neat and coloured to suit the room.
What new build mastic looks like in Roffey
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

FAQs for Roffey
Is Roffey within the area you cover?
Yes, Roffey is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Littlehaven station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear quote.
Can you work from my snagging list?
Yes. Send us the sealant items on the list, with pictures if you can, and we’ll quote. We will flag anything that needs another trade.
Do you work for hotels and businesses?
Yes. We can plan bigger jobs in stages to suit the site.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will tell you what we are using.
Why has my new-build shower seal failed already?
It’s common, and there are normally two reasons: movement as the house dries and settles, and sealant laid onto dust without primer. A proper reseal deals with both.
Who should fix failed sealant in a new build?
While the snagging or warranty period runs, the builder should be your first contact. If they’re slow or the fix doesn’t last, we can help.
How long will you be here?
Typically it takes a few hours in a single home. Bigger jobs take longer.

Related advice
Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
