About our new build mastic in Hildenborough
Building dust is behind a lot of failed new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the new bead bonds properly instead of bonding to the dust. Typical jobs include messy sealant that spoils new finishes and gaps opening as the house dries out and settles, across windows & doors, kitchens and show homes.
Older homes in small places like Hildenborough often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
We stand behind the work with a one-year guarantee, so you’re covered after we’ve gone.

Why deal with it now?
A tube of sealant from the DIY shop will not fix the cause: dust, no primer and old sealant left in the joint. Cutting out, cleaning and priming are what make the difference. Older cottages and farmhouses around Hildenborough can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.

Will there be a smell?

How much does new build mastic cost in Hildenborough?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
How long before the joint can be used?
Different products cure at different speeds, so follow the cure time we give you when we finish.
Can you match the sealant colour to my new kitchen or bathroom?
That depends on what the joint meets: white or clear for most sanitary joints, colours for worktops, floors and frames. We agree the colour before any work starts.
Signs you need new build mastic in Hildenborough
Later trades and the final clean can damage fresh sealant. If it’s disturbed before curing, the joint can be left weak.
If you can see any of these, it’s time to have the joints looked at:
- Smeared, uneven beads picked up at snagging
- New-build shower sealant that has already split
- Cracks appearing as a new home settles
- Sealant applied over dusty or wet surfaces
If you’ve bought a new home near Hildenborough station, the sealant around baths, showers and frames is worth checking in the first year or two.

Different surfaces, different methods
Windows and doors
On new builds, external frame sealant can be patchy. It’s resealed with an exterior sealant suited to the frame and wall.
Show homes
We can refresh show-home sealant that has discoloured or been knocked. The old bead comes out and a clean new one goes in.
What we cannot put right
We won’t take on work that won’t last, so here’s what sealant can’t put right:
- Structural cracks in walls or ceilings
- Deciding who is responsible under a builder’s warranty
- Leaking fittings rather than failed sealant
If you’re not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer.
Surfaces we seal

- Windows & doors
