West Wickham New Build Mastic
Plot mastic for developers and snagging failed sealant in new homes for homes and businesses in West Wickham and across Greater London. ARBOMaster approved applicators, fully insured, with a one-year guarantee.
- Sealant work across a run of new homes
- Cracks appearing as a new home settles
- Smeared, uneven beads picked up at snagging
How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Clean sealant with mild detergent, not abrasives
- Open a window or run the fan after bathing
- Keep water off fresh sealant until it has cured
- Look at the sealant regularly in the first couple of years
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
Early snagging is easier snagging. Left alone, a small crack can become a leak in a busy bathroom.
About our new build mastic in West Wickham
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. Both get the same care over preparation since hurried prep is behind a lot of new-build failures. We work on plot handovers, skirting & floors and windows & doors, and common reasons people get in touch are second-fix sealing on new plots and skirting joints opening in the first winter.
Across London, commercial floors have movement joints that break down under heavy foot traffic, while new homes need a neat, sound finish around frames, baths and kitchens before handover.
Big or small, it’s backed by our one-year guarantee in West Wickham and across Greater London.

Why deal with it now?
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. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler for homes in West Wickham.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, call 0345 464 0079 or drop us an email for an honest opinion and a quote.

New build mastic in West Wickham: local notes
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Many of London’s new homes are flats in bigger developments, where snagging may go through the developer or managing agent.
For new homes near West Wickham station, it’s worth checking the sealant early, while snags are still fresh.

The process
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and clear up. It usually takes a few hours in a single home. In West Wickham, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Before we arrive
- Clear the area around the work
- Where the joints are inside, avoid wetting them before we arrive
- Keep pets and children clear of the area while we work
How to get a quote

Related advice
Common problems we fix in West Wickham
Once people move in, baths and trays take weight and bed down. A bath sealed empty drops slightly when filled, straining the joint and the sealant may split.
It’s worth asking for a quote if you see:
- Untidy sealant flagged on a snagging list
- Kitchen sealant that has pulled off the wall
- Shower seals failing in the first year or two
- Gaps opening as the house dries out and settles
West Wickham is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.
