Advice
New build mastic in Dunsfold, done properly
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. In both, preparation makes the difference, because that is what rushed new-build sealant normally lacks. If you have gaps behind new kitchen upstands and untidy sealant flagged on a snagging list, we can help, on bathrooms & en suites, windows & doors and kitchens alike.
Older homes in small places like Dunsfold often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
Each job carries a 12-month guarantee, whatever its size.

What else we do in Dunsfold
DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Different surfaces, different methods
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
Skirting and floors
New homes often develop a gap between skirting and floor. We seal it with a flexible sealant that copes with the movement.

Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Keep photos and emails about snagging items
- Ventilate bathrooms well, especially in the first year
- Get a leaking seal dealt with straight away
- Look at the sealant regularly in the first couple of years
Keep photos of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
Report failed sealant to the builder while you are in the snagging period. Once it ends, the repair may be down to you.
Signs you need new build mastic in Dunsfold
Not every new-build joint gets the right sealant: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Both fail early.
The problems people generally mention when they call are:
- Frame joints opening as the plaster dries
- Sealant that never bonded to the surface
- Sealant work across a run of new homes
- Messy sealant that spoils new finishes
For new homes near Witley station, it’s worth checking the sealant early, while snags are still fresh.
