Why act early in Sevenoaks Weald
For developers, getting the sealant right first time saves return visits. Snagging visits for failed sealant cost time on every plot and most come down to preparation. Older cottages and farmhouses around Sevenoaks Weald can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Doing several joints on one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. We will send you a clear quote for the lot.
Why us?
- Neat joints and a tidy finish
- Experience in homes, commercial sites and hotels
- Approved under the ARBOMaster scheme
- Colour picked to suit the job

New build mastic in Sevenoaks Weald
Dust is the enemy of new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the new bead bonds properly rather than sitting on a layer of grit. If you’re dealing with beads laid onto grit and dust from the build and gaps between new skirting and floors, we can help, whatever the surface.
Around Sevenoaks Weald, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Report sealant problems to your builder during the snagging period
- Photograph failed sealant before it’s redone
- Follow the cure time we give you
- Ventilate bathrooms well, especially in the first year
Do not stand on the bath edge or the lip of the tray. Report any movement in a bath or tray.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in keeps the job straightforward.
Do you need new build mastic in Sevenoaks Weald?
If plaster or screed was still damp when it was sealed, the bond suffers. On a busy site, joints aren’t always given time to dry before the sealant goes on.
Most people get in touch when they notice something like this:
- Sealant that never bonded to the surface
- Cracked caulk along new skirting
- Gaps opening as the house dries out and settles
- Frame joints opening as the plaster dries
Around Sevenoaks Weald, as everywhere, new build mastic is only as good as the preparation behind it.
What to look for in a quote
- How long to leave it before use
- Which colour the sealant will be
- Whether all the old sealant comes out first
- Which sealant they’ll use, and why
For landlords and businesses
We also work for property managers and facilities teams. We can quote a run of properties together, and we’re fully insured.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
What affects the quote in Sevenoaks Weald
There’s no set price list, because no two jobs are the same. The quote depends on:
- The type of sealant required
- The number of rooms or windows
- Whether there’s mould to deal with
- Any working-time requirements on site
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.
What to tell us for a quote
Photos by email are helpful but not essential. Try to tell us:
- Whether it’s a home or a business
- The problem you’ve noticed
- How many joints, rooms or windows are involved
- Any previous sealing or DIY work
