New build mastic in Wareside
New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, and sealant applied in a hurry at handover can split. If you are dealing with skirting joints opening in the first winter and second-fix sealing on new plots, we can help.
Somewhere as small as Wareside, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
A one-year guarantee comes as standard, so you are covered after we’ve gone.

Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What the job involves on each surface
Show homes
Show homes need sealant that looks right from day one. Every bead is neat and coloured to suit the room.
Plot handovers
Plot mastic is carried out to the developer’s schedule. Each joint is cleaned and primed where needed.
What we do, step by step
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself usually takes a few hours in a single home, depending on the size of the job. For a village or hamlet like Wareside, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Before we arrive
- Mention any tricky access
- Mention any leaks or damp you’ve noticed
- Clear items away from the joints we’re working on

Do you need new build mastic in Wareside?
Not every new-build joint gets the right sealant: caulk where water collects, or a rigid product on a moving joint. Both fail early.
Common reasons people contact us include:
- Joints pulling apart as timber shrinks
- Shower seals failing in the first year or two
- Second-fix sealing on new plots
- Kitchen sealant that has pulled off the wall
Around Wareside, as everywhere, new build mastic is only as good as the preparation behind it.

Landlord and commercial work in Wareside
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Failed sealant is one of the commonest items on a check-out report. Several properties can go on one quote.
Why act early in Wareside
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it will not bond to the old layer. A lasting seal starts with removing the old one completely. Where a wall is exposed, as many are in small places like Wareside, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Combining jobs into one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
