New-build mastic & snagging in Hanworth, Bracknell Forest
We cover Hanworth for plot mastic for developers and snagging failed sealant in new homes. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Cracks appearing as a new home settles
- Gaps between new skirting and floors
- Sealant work across a run of new homes
Looking after it afterwards
Aftercare is simple:
- Avoid running a DIY bead over the old one
- Wait for the cure time before using a resealed shower
- Photograph failed sealant before it’s redone
- Check bath and shower seals every few months as the house settles
Watch the joints as the house settles. Small gaps can appear as the house dries, and they’re simple to reseal once movement has slowed.
Report failed sealant to the builder while you’re in the snagging period. Once it ends, the repair may be down to you.
New build mastic for homes and businesses in Hanworth
Some owners wait for the first year’s movement before having joints redone. For small cosmetic gaps, that is reasonable, but a failed shower or bath seal shouldn’t wait. If you are dealing with gaps behind new kitchen upstands and frame joints opening as the plaster dries, we can put it right.
In and around Hanworth, floors range from older timber boards to tiles and newer finishes, from timber that moves with the seasons to tiles laid on concrete. Skirting and threshold joints need a sealant that suits the floor.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What new build mastic looks like in Hanworth

Show homes
We seal show-home bathrooms, kitchens and frames. We will plan around viewing times.
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.
Signs you need new build mastic in Hanworth
Baths and trays settle under load once the home is lived in. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and the sealant may split.
Most people get in touch when they notice one of these:
- Beads laid onto grit and dust from the build
- Messy sealant that spoils new finishes
- Kitchen sealant that has pulled off the wall
- Cracks appearing as a new home settles
Around Hanworth, as everywhere, new build mastic is only as good as the preparation behind it.

- Every bit of the old builder’s sealant is cut out.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
