Quotes for new build mastic in Dumpford
There’s no set price list, because jobs vary so much. The quote depends on:
- Whether there’s mould to deal with
- How much old sealant there is and how hard it is to remove
- The number of rooms or windows
- Access and height
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.

New build mastic in Dumpford, done properly
Snagging sealant properly means taking the failed bead out completely. Fresh silicone cannot bond to the old layer, so the joint is cut out, cleaned, dried and resealed. We work on kitchens, show homes and skirting & floors, and people most often call us about sealant applied over dusty or wet surfaces and smeared, uneven beads picked up at snagging.
In a village or hamlet like Dumpford, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

How to look after the new joints
Good habits help new joints last longer. A few tips:
- Don’t seal over failed sealant yourself
- Record problems with dated photos
- Avoid scourers and strong chemicals on sealant
- Wait for the cure time before using a resealed shower
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day before water reaches them.
Report failed sealant to the builder while you’re in the snagging period. After that, putting it right may fall to you.
Leave it or put it right?
Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time and most come down to preparation. Older cottages and farmhouses around Dumpford can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.
