About our new build mastic in Upper Green
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. If you’re dealing with sealant applied over dusty or wet surfaces and gaps behind new kitchen upstands, we can help, on kitchens, plot handovers and skirting & floors alike.
Somewhere as small as Upper Green, 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.
You get a 12-month guarantee, the same in Upper Green as everywhere else we work.

DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What we cannot put right
It helps to know what we can’t do too:
- Disputes or warranty claims with your builder
- Leaking fittings rather than failed sealant
- Damaged fittings that need replacing
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think.
What we seal

- Skirting & floors

What else we do in Upper Green
Leave it or put it right?
DIY kits do not solve the main problems with new-build sealant: dust, no primer and old sealant left in the joint. Cutting out, cleaning and priming are what make the difference. In a small place like Upper Green, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
What you get with us
- Domestic, commercial and hotel work
- We never seal over old sealant
- Anti-fungal sanitary silicone in wet areas
- Neat joints and a tidy finish
How the job changes by surface
Plot handovers
Send us the schedule and any sealant specification and we’ll quote. Sealant work across the plot is covered to the agreed spec.
Kitchens
Beside the sink, the joint takes water every day. We use a sealant suited to kitchens suited to the job.
