New build mastic in Langley, done properly
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first, and if it isn’t put right, get in touch with us. If you are dealing with skirting joints opening in the first winter and cracks appearing as a new home settles, we can help, on bathrooms & en suites, plot handovers and show homes alike.
Somewhere as small as Langley, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
Whatever the size of the job, it’s backed by our 12-month guarantee in Langley and across Kent.

Work for landlords, hotels and businesses
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
Hotels need rooms back in use, so we plan the work room by room. We’ve worked in hotels as well as homes and businesses.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Keep photos and emails about snagging items
- Raise failed sealant with the developer while you are covered
- Follow the cure time we give you
- Do not wait for the house to settle if water is getting through
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day to cure enough for use.
Early snagging is easier snagging. Left alone, a small crack can become a leak over time.
Your questions about new build mastic in Langley
Is Langley in your area for new build mastic?
Yes, Langley is within the area we cover. Our work covers 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.
Do you work for landlords with property near Bearsted station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just ring 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear price.
Will you just run a new bead over the existing one?
No. Fresh silicone does not stick to the old layer, so it soon lifts and traps water. The old sealant always comes out first.
Can you quote for more than one area?
Yes. Just list everything you need.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Do you remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Where are you based?
We work from Crawley. Our applicators cover Langley.
Surface by surface
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. The joint is stripped back before the new bead goes in.
Kitchens
Sink joints are wet all the time. We use a sealant suited to kitchens, food-safe where it’s needed.
How we quote for new build mastic
The quote reflects the job in front of us. We take into account:
- The size of the job
- How many areas need sealing
- Any working-time requirements on site
- Mould in or behind the old joints
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
What to tell us for a quote
You don’t need to know the technical terms. It helps if you can tell us:
- If it’s domestic, commercial or a hotel
- Roughly how big the job is
- Any previous sealing or DIY work
- The address or postcode of the job
For a quote, call 0345 464 0079 or send us an email and tell us where the job is and what the problem looks like. We’ll give you a clear price before any work starts.
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, 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.
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.
Honest limits
A few problems are outside what sealant work can do:
- Deciding who is responsible under a builder’s warranty
- Damaged fittings that need replacing
- Leaks from pipes, valves or wastes, which need a plumber
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly before you book.
What we seal
- Plot handovers
- Windows & doors
- Kitchens
- Bathrooms & en suites
- Skirting & floors
- Show homes
