New build mastic in Blackboys, done properly
Some new-home owners let the house settle before resealing. That makes sense for small gaps that are just cosmetic, but a seal that is letting water through needs doing now. Typical jobs include frame joints opening as the plaster dries and joints pulling apart as timber shrinks, across windows & doors, bathrooms & en suites and show homes.
For a small place like Blackboys, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or email us.

What happens on the day
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take a few hours in a single home.

We bring what the job needs, so it can be finished in one trip where possible.
- We go through the snagging list or plot schedule and agree the joints to do.
- The old bead comes out in full, with no layer left behind.
- Surfaces are cleaned of building dust and primed where needed.
- New sealant suited to each joint is applied and tooled neatly.
- Each area is checked and left with its cure time.

Honest limits
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Cracked trays, tiles or worktops
- Structural cracks in walls or ceilings
- Leaking fittings rather than failed sealant

Why it’s worth doing now in Blackboys
Small cosmetic gaps can wait for the house to settle, but a leaking seal cannot. Not sure whether yours can wait? You can ring 0345 464 0079 or drop us an email with a few pictures and we’ll tell you. In a small place like Blackboys, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.

Plot handovers
Good preparation at handover saves snagging later. We clean out building dust before sealing and prime where the product needs it.
Show homes
Show homes need sealant that looks right from day one. Every bead is neat and coloured to suit the room.
Common problems we fix in Blackboys
Sealant is often one of the last jobs before handover. Dusty, unprimed joints are common, and the sealant sits on grit instead of the surface.
The most common problems we see are:
- Messy sealant that spoils new finishes
- Beads laid onto grit and dust from the build
- Frame joints opening as the plaster dries
- Joints pulling apart as timber shrinks
Around Blackboys, as everywhere, new build mastic is only as good as the preparation behind it.
What your quote should include
- Are they insured?
- Whether the sealant suits the joint
- Which colour the sealant will be
- Whether they seal over old material or remove it
