About our new build mastic in Long Ditton
We never seal over a failed new-build bead. Fresh silicone can’t bond to the old layer, so the joint is cut out, cleaned, dried and resealed. If you’re dealing with sealant applied over dusty or wet surfaces and new-build shower sealant that has already split, we can put it right.
From brand-new flats to converted terraces with new flooring, London has every kind of floor. Every joint between floor, skirting and threshold has to cope with some movement.
A 12-month guarantee comes as standard, so you’re not left on your own once the job is done.

New build mastic around Long Ditton
Many of London’s new homes are flats in bigger developments, where snags may need reporting through the developer or the managing agent. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you’ve bought a new home near Surbiton station, the sealant around baths, showers and frames is worth checking in the first year or two.

Long Ditton: your questions answered
Is parking an issue for new build mastic in Long Ditton?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
Is Long Ditton in your area for new build mastic?
Yes. Our work covers London and the South East, and Long Ditton is part of that. Just call 0345 464 0079 or email us with a few details of the job.
How long will you be here?
A typical job takes a few hours in a single home. We’ll confirm how long when we quote.
Who should fix failed sealant in a new build?
Start with your builder while their snagging or warranty period runs. After that, or if their repair keeps failing, we can do it and our work is guaranteed for a year.
Can you match the sealant colour to my new kitchen or bathroom?
That depends on what the joint meets: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We agree the colour before work begins.
What do you need from me for a quote?
A short description and the location, with photos by email if possible. If we need more, we will ask.
Which products do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We’ll tell you what we’re using and why.
I’m a tenant. Can you help?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.
The process
There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes a few hours in a single home. In Long Ditton, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- The old bead comes out in full, with no layer left behind.
- Each joint is cleaned of dust and grit, then primed if required.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you’re given the cure time.
Getting ready for the visit
- Tell us about any water getting in
- Try not to wet indoor joints just before the visit
- Move anything stored near the joints

Do you need new build mastic in Long Ditton?
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 and the sealant has to cope with the movement.
Signs it’s time to call us include:
- Gaps opening as the house dries out and settles
- Internal frame sealant that has split
- Sealant applied over dusty or wet surfaces
- Shower seals failing in the first year or two
Long Ditton is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
How to look after the new joints
So the new joints stay in good condition:
- Use the extractor fan every time you shower
- Do not seal over failed sealant yourself
- Report sealant problems to your builder during the snagging period
- Do not wait for the house to settle if water is getting through
Avoid standing on the rim of the bath or the edge of the tray while the sealant cures. If a bath or tray moves when you stand in it, get it looked at.
Early snagging is easier snagging. Small faults turn into leaks if left in a busy bathroom.
