New build mastic for homes and businesses in Laleham
In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. Common call-outs are for untidy sealant flagged on a snagging list and plot mastic for developers ahead of handover, across bathrooms & en suites, windows & doors and show homes.
If you’ve bought a new home in or near Laleham, the first year or two is a good time to check the sealant. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.
You get a 12-month guarantee, the same in Laleham as everywhere else we work.

What affects the cost of new build mastic
Jobs vary more than people expect. The main factors:
- Any mould that needs treating
- How many areas need sealing
- Working hours on commercial sites
- Which sealant suits the joint
The cost reflects the work involved, not guesswork. That is why we ask a few questions first.
Asking for a quote
To help us quote quickly, let us know:
- Where the property is

- Photos by email, if that is easy

What we’re called out for in Laleham
Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint and the sealant may split.
Any of these means the joints need attention:
- Cracks appearing as a new home settles
- Skirting joints opening in the first winter
- Shower seals failing in the first year or two
- Untidy sealant flagged on a snagging list
Around Laleham, as everywhere, new build mastic is only as good as the preparation behind it.

What we cannot put right
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Leaking fittings rather than failed sealant
- Your warranty claim itself, which is between you and the builder
- Baths and trays that move too much for sealant to cope with
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think before booking.

DIY versus a professional finish
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Landlords, agents and businesses in Laleham
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.

Why deal with it now?
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it won’t bond to the old layer. A lasting seal starts with removing the old one completely. Around Laleham, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
