New build mastic for homes and businesses in Great Bookham
Snagging sealant properly means taking the failed bead out completely. New silicone will not bond to old silicone, so it all comes out before we clean, dry and reseal. Typical jobs include sealant work across a run of new homes and beads laid onto grit and dust from the build, on plot handovers, kitchens and show homes.
For a new home in or near Great Bookham, it’s worth checking the sealant early. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.
Your job is guaranteed for a year, as with all our work.

Leave it or put it right?
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it will not bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. In an older home around Great Bookham, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.
The cost depends on the amount of work, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts.
Why us?
- An ARBOMaster approved applicator
- Anti-fungal silicone where joints get wet

- A 12-month guarantee on all work

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
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.
Do you need new build mastic in Great Bookham?
When the heating goes on in the first winter, the house dries fast. Skirting, frames and worktops pull away slightly and cracks appear in the sealant.
The problems people generally mention when they call include:
- Messy sealant that spoils new finishes
- Internal frame sealant that has split
- Kitchen sealant that has pulled off the wall
- Joints pulling apart as timber shrinks
For new homes near Bookham station, it’s worth checking the sealant early, while snags are still fresh.

The process
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a few hours for most snagging lists, longer for a run of plots. Parking around Great Bookham is generally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We go through the snagging list or plot schedule and agree the joints to do.
- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Each area is checked and left with its cure time.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- Clear the area around the work

What the job involves on each surface
Skirting and floors
As timber and screed dry, skirting and floors shift. We use a flexible product rather than caulk in a colour to suit.
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We cut out the cracked bead and reseal with a flexible sealant in a matching colour.
