Do you need new build mastic in Aldersbrook?
Later trades and the final clean can damage fresh sealant. If it’s disturbed before curing, the joint can be left weak.
Most people get in touch when they notice one of these:
- Joints pulling apart as timber shrinks
- Kitchen sealant that has pulled off the wall
- Skirting joints opening in the first winter
- Sealant applied over dusty or wet surfaces
Aldersbrook is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

New build mastic in Aldersbrook, done properly
Snagging sealant properly means taking the failed bead out completely. New silicone will not bond to old silicone, so it all comes out before we clean, dry and reseal. Common call-outs are for second-fix sealing on new plots and frame joints opening as the plaster dries, on skirting & floors, kitchens and bathrooms & en suites.
Across London, commercial floors have movement joints that break down under heavy foot traffic, and new homes need their plot mastic finished properly before handover.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Different surfaces, different methods
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
Kitchens
New-kitchen sealant is often applied in a rush. We take it out and reseal neatly, colour-matched where it shows.
Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What we do, step by step
Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to several days, depending on the number of plots. In a London area like Aldersbrook, the main things to plan are parking and access: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- We go through the snagging list or plot schedule and agree the joints to do.
- The old bead comes out in full, with no layer left behind.
- Surfaces are cleaned of building dust and primed where needed.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Each area is checked and left with its cure time.
Getting ready for the visit
- On commercial sites, let us know about site rules
- Keep children and pets away from the work area
- Tell us if parking is tricky

New homes and floors in Aldersbrook
Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For new homes near Wanstead Park station, it’s worth checking the sealant early, while snags are still fresh.

Why act early in Aldersbrook
If you’re still in the builder’s snagging or warranty period, ask them to put it right first. If it keeps failing or is not dealt with, we can reseal it properly. 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 Aldersbrook.
What you pay reflects the work, not guesswork. That is why we ask a few questions first and send you a clear quote before any work starts.
