New-build mastic & snagging in Windlesham, Surrey
Plot mastic for developers and snagging failed sealant in new homes for homeowners, landlords and businesses in Windlesham. Fully insured, ARBOMaster approved and guaranteed for a year.
- Worktop and upstand sealant coming away
- Gaps between new skirting and floors
- Smeared, uneven beads picked up at snagging
New build mastic in Windlesham, done properly
We never seal over a failed new-build bead. New silicone will not bond to old silicone, so the joint is cut out, cleaned, dried and resealed. If you are dealing with cracks appearing as a new home settles and kitchen sealant that has pulled off the wall, we can put it right, on windows & doors, bathrooms & en suites and kitchens alike.
If you’ve bought a new home in or near Windlesham, the first year or two is a good time to check the sealant. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.
Every job is covered by a 12-month guarantee.

How the visit works
We keep the work tidy and contained to the joints we’re treating, so you can get on with your day. Expect the work to take anything from a few hours to several days, depending on the number of plots. For a job in Windlesham, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out down to clean surfaces.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Mention any sign-in or site rules at work premises
- Mention if the joints have been sealed before

- Deciding who is responsible under a builder’s warranty
- Broken tiles or a split tray
- Plumbing faults behind the sealant

Why act early in Windlesham
A quick bead over the top of the old sealant can look fine at first, but it cannot bond to what’s underneath. A lasting seal starts with removing the old one completely. In an older home around Windlesham, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference.
