What we’re called out for in Littlewick Green
A new house holds a lot of water from the build, which takes a year or two to dry out. As it does, timber shrinks and joints open and the sealant has to cope with the movement.
People normally contact us after spotting something like this:
- Joints pulling apart as timber shrinks
- Kitchen sealant that has pulled off the wall
- Internal frame sealant that has split
- New-build shower sealant that has already split
In and around Littlewick Green, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

New build mastic in Littlewick Green
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. If you’re still within the builder’s snagging or warranty period, tell them first and if that stalls, we can do it. If you’re dealing with joints pulling apart as timber shrinks and leaking shower tray seals in a new home, we can help, whatever the surface.
Older homes in small places like Littlewick Green often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
Every job is covered by our 12-month guarantee, wherever you are in Windsor and Maidenhead.

How it works
You don’t need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the job takes anything from a few hours to several days, depending on the number of plots for a typical job. Somewhere as small as Littlewick Green, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each joint is checked for movement before any work starts.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
Before we arrive
- Keep pets and children clear of the area while we work
- Let us know about earlier repairs to the joints
- Tell us about any water getting in

What else we do in Littlewick Green
Why it’s worth doing now in Littlewick Green
A quick bead over the top of the old sealant can look fine at first, but it cannot bond to what’s underneath. A lasting seal starts with removing the old one completely. Around Littlewick Green, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Doing several joints on one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

Different surfaces, different methods
Show homes
Tired or marked sealant in a show home can be renewed. The old bead comes out and a clean new one goes in.
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. We reseal once the old bead is fully out and baths are filled before sealing.

Looking after it afterwards
A little care helps the new joints last. We recommend:
- Use the extractor fan every time you shower
- Wait for the cure time before using a resealed shower
- Don’t wait for the house to settle if water is getting through
- Photograph failed sealant before it’s redone
Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry and can be resealed later.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant.
