What the job involves on each 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 and baths are filled before sealing.
Skirting and floors
Gaps under skirting are one of the most common new-build snags. We seal it with a flexible sealant that copes with the movement.
New build mastic for homes and businesses in Letcombe Bassett
Some owners wait for the first year’s movement before having joints redone. For small cosmetic gaps, that’s reasonable, but a seal that’s letting water through needs doing now. We work on skirting & floors, bathrooms & en suites and show homes, and people most often call us about messy sealant that spoils new finishes and worktop and upstand sealant coming away.
For a small place like Letcombe Bassett, the journey and access are planned in advance, and the work itself is the same as on any site.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

Common questions in Letcombe Bassett
Is there a guarantee on new build mastic in Letcombe Bassett?
All our work, in Letcombe Bassett and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Can you do new build mastic in Letcombe Bassett?
Yes, Letcombe Bassett is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or email us with a few details of the job.
What does new build mastic cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we’ll talk you through it.
How long should I leave it?
Different products cure at different speeds, so please follow the time we give you.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
Can new sealant go on top of the old bead?
No. We always remove the existing bead, then clean and prime the joint, and a new bead applied.
Why has my new-build shower seal failed already?
New homes dry out and move in their first couple of years, and sealant is often rushed onto dusty, unprimed surfaces. Both lead to early failure.
Do you take out the old sealant first?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
What new build mastic looks like in Letcombe Bassett
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.

It normally takes a few hours in a single home. For a village or hamlet like Letcombe Bassett, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- We cut out every bit of the failed or messy sealant.
- We clean off dust from the build and prime the surfaces where the product needs it.
- New sealant suited to each joint is applied and tooled neatly.
- Each area is checked and left with its cure time.

DIY sealant or a professional job?
If you’re set on DIY, put the effort into 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.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

How we quote for new build mastic
You will get a clear quote before work begins. It takes into account:
- When we can work, for business premises
- The size of the job
- The old material and how stubborn it is
- Which sealant suits the joint
Doing several joints on one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.
What we need to know
Before you ask for a quote, have a think about:
- The rough size of the job
- What’s wrong with the joints now
- Photos by email, if that’s easy
- If it’s domestic, commercial or a hotel
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. When it suits you, ring 0345 464 0079 or email us.
Work for landlords, hotels and businesses
We work for landlords and letting agents as well as householders. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Honest limits
We’d rather tell you now than do work that won’t last, so these are the limits:
- Structural cracks in walls or ceilings
- Deciding who is responsible under a builder’s warranty
- Leaking fittings rather than failed sealant
If you’re not sure, just phone 0345 464 0079 or email us and we will give you a straight answer before booking.
