New build mastic for homes and businesses in Lindsell
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 reaches anything behind it. If you are dealing with plot mastic for developers ahead of handover and sealant that never bonded to the surface, we can put it right, on kitchens, skirting & floors and plot handovers alike.
In a village or hamlet like Lindsell, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
All of our work is guaranteed for twelve months.

Advice
DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, 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.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
What we’re called out for in Lindsell
Fresh sealant can be knocked or cut by trades finishing off. A bead disturbed before it has cured may never seal properly and it shows once the home is in use.
Most people get in touch when they notice something like this:
- Leaking shower tray seals in a new home
- Cracked sealant around new window and door frames
- Plot mastic for developers ahead of handover
- Gaps opening as the house dries out and settles
In and around Lindsell, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Different surfaces, different methods
Show homes
We seal show-home bathrooms, kitchens and frames to a tidy standard. Tell us when the home is open so we can plan around it.
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
Why deal with it now?
A quick bead over the top of the old sealant can look fine at first, but it won’t bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. Around Lindsell, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

- White, clear, grey or coloured to suit, where the product allows

Aftercare tips
Looking after new joints is easy:
- Keep water off fresh sealant until it has cured
- Raise failed sealant with the developer while you’re covered
- Check bath and shower seals every few months as the house settles
- Keep photos and emails about snagging items
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant.
New build mastic around Lindsell
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Whether the job is in Lindsell itself or nearby, the right material for each joint matters as much as a neat finish.
