How we handle new build mastic in Motspur Park
Building dust is behind a lot of failed new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the sealant actually sticks rather than sitting on a layer of grit. We work on windows & doors, plot handovers and skirting & floors, and common reasons people get in touch are shower seals failing in the first year or two and second-fix sealing on new plots.
Shops, offices and commercial units across London have hard-wearing floors with movement joints that need resealing as they wear, while new homes need a neat, sound finish around frames, baths and kitchens before handover, in Motspur Park and beyond.
Every job comes with a 12-month guarantee, wherever you are in Greater London.

- Every bit of the old builder’s sealant is cut out.

Why act early in Motspur Park
It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times for the lot. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
The cost depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts.

What we’re called out for in Motspur Park
New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart, and sealant that cannot keep up splits.
Most people get in touch after spotting one of these:
- New-build shower sealant that has already split
- Internal frame sealant that has split
- Sealant that never bonded to the surface
- Second-fix sealing on new plots
Motspur Park is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

What affects the quote in Motspur Park
For a quick quote, just ask. The main things that affect it are:
- Access and height
- Mould in or behind the old joints
- When we can work, for business premises
- Which sealant suits the joint
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, call 0345 464 0079 or send us an email for an honest opinion and a quote.
What to tell us for a quote
To help us quote quickly, please include:
- Access, such as stairs, a lift or height
- The problem you’ve noticed
- Where the job is, and your postcode
- Pictures of the joints, sent by email
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.
What we cannot put right
In fairness, there are a few things sealant won’t fix:
- Cracked trays, tiles or worktops
- Your warranty claim itself, which is between you and the builder
- Settlement cracks that need a surveyor
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly.
Surfaces we seal
- Skirting & floors
- Plot handovers
- Bathrooms & en suites
- Kitchens
- Windows & doors
- Show homes
Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Do not wait for the house to settle if water is getting through
- Keep photos and emails about snagging items
- Put sealant faults on your snagging list early
- Open a window or run the fan after bathing
Watch the joints as the house settles. Small gaps can appear as the house dries and can be resealed later.
Don’t let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you.
Joints and finishes in Motspur Park homes
Many of London’s new homes are flats in bigger developments, where snagging may go through the developer or managing agent. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For new homes near New Malden station, it’s worth checking the sealant early, while snags are still fresh.
