About our new build mastic in Betsham
In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. If you have kitchen sealant that has pulled off the wall and new-build shower sealant that has already split, we can put it right.
Around Betsham, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

FAQs for Betsham
Can you do new build mastic in Betsham?
Yes. Our work covers London and the South East, and Betsham is part of that. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear quote.
Do you work for landlords with property near Longfield station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can phone 0345 464 0079 or email us with the details for a clear quote.
How long will you be here?
As a guide, most jobs take anything from a few hours to several days, depending on the number of plots. Larger jobs naturally take longer.
Is it messy?
No. The area is protected while we work and cleaned up afterwards.
Can you quote for more than one area?
Yes. Just list everything you need and you will get one quote.
Do the sealants smell?
Some sealants have a smell while they cure. Opening a window helps.
Can you reseal over the builder’s sealant?
No. Fresh silicone does not stick to the old layer, so sealing over the top fails quickly. The old sealant always comes out first.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.
Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
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.
What affects the quote in Betsham
The price is agreed before any work begins. It’s based on:
- Working hours on commercial sites
- Which sealant suits the joint
- How many rooms, windows or areas are involved
- Whether there’s mould to deal with
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts.
Asking for a quote
What to tell us when you ask for a quote:
- Where the job is, and your postcode
- How we’d reach the joints
- The rough size of the job
- A few pictures by email, if you can
Every job is quoted individually, so start by telling us what you need. Just phone 0345 464 0079 or drop us an email with the details, and pictures are welcome.
Signs you need new build mastic in Betsham
If plaster or screed was still damp when it was sealed, the bond suffers. Site programmes don’t always leave time for joints to dry before the sealant goes on.
Common reasons people contact us are:
- Sealant that never bonded to the surface
- Skirting joints opening in the first winter
- Gaps opening as the house dries out and settles
- Messy sealant that spoils new finishes
In and around Betsham, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Leave it or put it right?
The builder is usually the first port of call while the snagging or warranty period runs. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. Around Betsham, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
