New build mastic for homes and businesses in Clayton
Building dust is behind a lot of failed new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the new bead bonds properly instead of bonding to the dust. We are often asked to deal with internal frame sealant that has split and sealant work across a run of new homes, on kitchens, bathrooms & en suites and windows & doors.
Work in a small place like Clayton just needs the journey and access planning, and the work itself is the same as on any site.
There’s a 12-month guarantee on every job, whatever its size.

DIY sealant or a professional job?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Looking after it afterwards
Aftercare is simple:
- Raise failed sealant with the developer while you’re covered
- Act quickly if a seal starts to leak
- Follow the cure time we give you
- Keep pictures and emails about snagging items
Avoid standing on the rim of the bath or the edge of the tray in the first few weeks. Report any movement in a bath or tray.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.

What the job involves on each surface
Kitchens
Worktops in new homes can move slightly as the house dries, opening gaps behind the upstand. A fresh flexible bead closes them.
Plot handovers
Good preparation at handover saves snagging later. Dust from the build is removed first and primer used where needed.
What we do, step by step
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. Most jobs take anything from a few hours to several days, depending on the number of plots. Somewhere as small as Clayton, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we work through your snagging list or plot schedule with you.
- Failed or untidy sealant is cut out completely.
- Surfaces are cleaned of building dust and primed where needed.
- We apply a sealant that suits each joint and tool it to a neat finish.
- We check every joint and tell you how long each needs to cure.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about stairs, lifts or work at height

Clayton questions
I let a flat near Hassocks station. Can you help?
Yes, we work for landlords and agents. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before any work starts.
Will you come out to Clayton?
Yes, Clayton is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint.
Why does sealant fail so quickly in new builds?
It’s common, and there are normally two reasons: the house moving as it dries, and sealant that never bonded properly. Cutting it out and resealing properly fixes both.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We’ll tell you what we are using and why.
Do you hold any approvals?
Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Is there any odour?
Some sealants have a smell while they cure. Opening a window helps.
How long does new build mastic take?
Most jobs take anything from a few hours to several days, depending on the number of plots. Your quote will say how long we expect yours to take.

What new build mastic looks like in Clayton
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Around Clayton, as everywhere, new build mastic is only as good as the preparation behind it. For new homes near Hassocks station, it’s worth checking the sealant early, while snags are still fresh.
