New build mastic for homes and businesses in East Garston
Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover. Common call-outs are for plot mastic for developers ahead of handover and gaps opening as the house dries out and settles, on bathrooms & en suites, kitchens and skirting & floors.
Somewhere as small as East Garston, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
Whatever the size of the job, you get the same 12-month guarantee.

Common questions in East Garston
Do you cover smaller places like East Garston?
Yes, East Garston 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.
Is new build mastic in East Garston guaranteed?
Every job comes with our one-year guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
How do I get a quote for new build mastic in East Garston?
Size, access and the old material all affect the cost. Ask us for a quote.
Will you just run a new bead over the existing one?
No. New silicone won’t bond to old silicone, so it soon lifts and traps water. We cut the old bead out completely.
When is the best time to reseal in a new build?
It depends on whether water is getting through. Failed seals in wet areas need doing now, but cosmetic gaps can wait for movement to slow.
Can I add another job to the visit?
Of course. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
Can I send you my snagging list?
Yes. Photos of each sealant item help us quote. If something is not sealant, we’ll say so.
Are you fully insured?
Yes, we’re fully insured.
DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
What sealant work cannot fix
To be straight with you, there are a few things sealant won’t fix:
- Broken tiles or a split tray
- A tray or bath that is not properly supported, until it’s fixed
- Settlement cracks that need a surveyor
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly.

Common problems we fix in East Garston
When the heating goes on in the first winter, the house dries fast. Gaps open along skirting, frames and worktops.
Keep an eye out for these signs:
- Cracked caulk along new skirting
- Sealant work across a run of new homes
- Beads laid onto grit and dust from the build
- Worktop and upstand sealant coming away
For jobs in and around East Garston, choosing the right material for each joint is as important as a tidy finish.

- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.

Why it’s worth doing now in East Garston
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it won’t bond to the old layer. A lasting seal starts with removing the old one completely. In a small place like East Garston, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Why book with us
- 20+ years of sealant experience
- White, clear, grey or another colour, product permitting
- We’re fully insured
- Sealant colour chosen to suit
