New-build mastic & snagging in West Street, Kent
Plot mastic for developers and snagging failed sealant in new homes for householders, landlords and businesses in West Street. Fully insured, ARBOMaster approved and guaranteed for a year.
- Messy sealant that spoils new finishes
- Gaps behind new kitchen upstands
- Sealant work across a run of new homes
How to look after the new joints
Looking after new joints is easy:
- Resist patching a failed seal with a tube from the DIY shop
- Wipe joints with warm soapy water
- Raise failed sealant with the developer while you are covered
- Wait for the cure time before using a resealed shower
Follow the cure time we give you before the area gets wet. Silicone is normally left for about a day.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Small faults turn into leaks if left over time.
How we handle new build mastic in West Street
A new house keeps drying out and settling for its first couple of years. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. We work on kitchens, windows & doors and plot handovers, and common reasons people get in touch are untidy sealant flagged on a snagging list and kitchen sealant that has pulled off the wall.
Older homes in small places like West Street often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

What happens if it’s left?
DIY kits do not solve the main problems with new-build sealant: dust, no primer and old sealant left in the joint. Cutting out, cleaning and priming are what make the difference. In a small place like West Street, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

What the job involves on each surface
Kitchens
Worktops in new homes can move slightly as the house dries, opening gaps behind the upstand. We reseal them with a flexible sealant.
Windows and doors
External mastic around new windows and doors is sometimes rushed or missed. It’s resealed with an exterior sealant suited to the frame and wall.
Common problems we fix in West Street
If plaster or screed was still damp when it was sealed, the bond suffers. On a busy site, joints are not always given time to dry before the sealant goes on.
Common reasons people contact us are:
- Sealant work across a run of new homes
- Gaps opening as the house dries out and settles
- Kitchen sealant that has pulled off the wall
- Messy sealant that spoils new finishes
In and around West Street, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Questions to ask before booking

Related advice
Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you are 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 fails, we can still redo it.
