New build mastic in Ashtead
Some new-home owners let the house settle before resealing. That makes sense for small gaps that are just cosmetic, but a failed shower or bath seal shouldn’t wait. If you have gaps between new skirting and floors and gaps behind new kitchen upstands, we can help, whatever the surface.
In a town like Ashtead, skirting and floor joints open up as homes settle and floors move with the seasons. Those joints need a flexible sealant, as rigid filler soon cracks out.
Whatever the size of the job, you get the same 12-month guarantee in Ashtead and across Surrey.

- The failed sealant is removed completely.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.

Advice
For landlords and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we’ll quote.
When to call us in Ashtead
Sealant is often one of the last jobs before handover. Dusty, unprimed joints are common, and the sealant sits on grit instead of the surface.
Signs it’s time to call us include:
- Skirting joints opening in the first winter
- Gaps behind new kitchen upstands
- Leaking shower tray seals in a new home
- Frame joints opening as the plaster dries
In and around Ashtead, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
