Why deal with it now?
DIY kits do not solve the main problems with new-build sealant: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. Older cottages and farmhouses around Clapper Hill 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 amount of work, how much old material has to come out and access to the work. You will have a clear quote before any work starts.

About our new build mastic in Clapper Hill
A new build should have a neat, sound bead at every joint. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water gets into the floor or walls. If you’re dealing with shower seals failing in the first year or two and cracked sealant around new window and door frames, we can help.
Somewhere as small as Clapper Hill, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
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.

Send us the schedule and any sealant specification. Sealant work across the plot is covered to the agreed spec.
Signs you need new build mastic in Clapper Hill
New homes are full of moisture from plaster, screed and concrete, which takes a year or two to dry out. Drying timber shrinks and pulls joints apart.
Look out for these signs:
- Frame joints opening as the plaster dries
- Skirting joints opening in the first winter
- Plot mastic for developers ahead of handover
- Untidy sealant flagged on a snagging list
In and around Clapper Hill, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
What to look for in a quote
- What happens if they find a problem under the old sealant
- Whether VAT is included
- Which sealant they’ll use, and why
- What guarantee comes with the work
What sealant work cannot fix
New sealant can’t fix everything, and we’d rather say so up front. Sealant will not put right:
- A tray or bath that is not properly supported, until it’s fixed
- Settlement cracks that need a surveyor
- Cracked trays, tiles or worktops
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think before booking.

How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Keep pictures and emails about snagging items
- Ventilate bathrooms well, especially in the first year
- Clean sealant with mild detergent, not abrasives
- Raise failed sealant with the developer while you’re covered
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
Report failed sealant to the builder while you’re in the snagging period. Once it ends, the repair may be down to you, so raise it early.
How it works
We keep the work tidy and contained to the joints we are treating, so you can carry on as normal. The job normally takes anything from a few hours to several days, depending on the number of plots, and we tell you how long to leave it before we go. In a small place like Clapper Hill, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- We cut out every bit of the failed or messy sealant.
- We clean off dust from the build and prime the surfaces where the product needs it.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you’re given the cure time.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Mention any parking rules near the property
- Mention any leaks or damp you’ve noticed

Advice
For landlords and businesses
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
We work for landlords and letting agents as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.
