DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
New build mastic for homes and businesses in Sheerness
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. While the builder’s snagging or warranty period runs, report it to them first and if that stalls, we can do it. We work on show homes, windows & doors and bathrooms & en suites, and the jobs we see most are shower seals failing in the first year or two and sealant applied over dusty or wet surfaces.
For a new home in or near Sheerness, it’s worth checking the sealant early. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.
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.

FAQs for Sheerness
Do you cover Sheerness for new build mastic?
Yes. We work across London and the South East, and Sheerness is part of that. Just call 0345 464 0079 or email us with a few details of the job.
Do you cover smaller places like Sheerness?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Is it worth resealing while the house is still settling?
Any seal that is leaking should be redone right away. Cosmetic gaps can wait until the first year or two of movement has passed.
Can you work from my snagging list?
Yes. Photos of each sealant item help us quote. If something isn’t sealant, we will say so.
Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. Indoors, that generally means someone at home.
How long does the job take?
Most jobs take a few hours for most snagging lists, longer for a run of plots, including the preparation. Your quote will say how long we expect yours to take.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Can landlords and businesses book you?
Yes. We work in homes, commercial premises and hotels, and we’re fully insured.

What new build mastic looks like in Sheerness
Sheerness is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In and around Sheerness, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

How the job changes by surface
Skirting and floors
As timber and screed dry, skirting and floors shift. We use a flexible product rather than caulk.
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. The joint is stripped back before the new bead goes in and baths are filled before sealing.
What happens if it’s left?
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Resealing promptly protects the new finishes around it. Around Sheerness, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before work begins.
