New-build mastic & snagging in Higham Hill, Greater London
We cover Higham Hill for plot mastic for developers and snagging failed sealant in new homes. Old sealant removed completely, joints prepared properly.
- Gaps between new skirting and floors
- Untidy sealant flagged on a snagging list
- Shower seals failing in the first year or two
New build mastic for homes and businesses in Higham Hill
Developers send us the plot schedule and we work through it. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over with a sealant suited to each area. We work on kitchens, plot handovers and show homes, and common reasons people get in touch are gaps behind new kitchen upstands and sealant work across a run of new homes.
Much of London’s new housing is flats in larger developments. In a new development, snags are often reported through the developer or the managing agent, and failed shower seals, open skirting joints and gaps at thresholds are typical.
Big or small, it’s backed by our one-year guarantee.

- Movement caused by a poorly fitted tray or bath
- Leaking fittings rather than failed sealant

DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
How it works
Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from a few hours to several days, depending on the number of plots. In Higham Hill, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Mention any tricky access
- Mention any sign-in or site rules at work premises

Where are you based?

Will you just run a new bead over the existing one?
No. Sealing over old sealant looks fine for a few weeks, then lifts. We remove every bit of the old bead before resealing.

Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Is there any odour?
Possibly a little. It fades as the sealant cures.

New homes and floors in Higham Hill
Many of London’s new homes are flats in bigger developments, where snags may need reporting through the developer or the managing agent. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For new homes near Northumberland Park (London) station, it’s worth checking the sealant early, while snags are still fresh.

Look out for any of the following:
- Untidy sealant flagged on a snagging list
- Skirting joints opening in the first winter
- Second-fix sealing on new plots
- Sealant that never bonded to the surface

Keeping the joints in good condition
So the new joints stay in good condition:
- Use the extractor fan every time you shower
- Avoid scourers and strong chemicals on sealant
- Raise failed sealant with the developer while you’re covered
- Act quickly if a seal starts to leak
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries, and they’re simple to reseal once movement has slowed.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black keeps the job straightforward.
