What new build mastic looks like in Golders Green
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent.
For new homes near Cricklewood station, it’s worth checking the sealant early, while snags are still fresh.

New build mastic in Golders Green, done properly
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, because that’s what rushed new-build sealant usually lacks. We work on windows & doors, kitchens and bathrooms & en suites, and people most often call us about joints pulling apart as timber shrinks and sealant applied over dusty or wet surfaces.
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, in Golders Green and beyond.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

What else we do in Golders Green
Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Act quickly if a seal starts to leak
- Record problems with dated pictures
- Put sealant faults on your snagging list early
- Watch for new gaps as the house dries out
Avoid standing on the rim of the bath or the edge of the tray while the sealant cures. Report any movement in a bath or tray.
Early snagging is easier snagging. Left alone, a small crack can become a leak over time.
DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
What happens if it’s left?
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 a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Combining jobs into one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll give you a clear quote for the lot.

FAQs for Golders Green
Do you work for landlords with property near Cricklewood station?

How long before the joint can be used?

Do you use white or clear sealant?
Most bathroom joints are white or clear, but other colours are available. We choose one to suit the room.
Should I wait before resealing?

What do you need from me for a quote?

Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We’ll tell you what we are using and why.
When to call us in Golders Green
Baths and trays settle under load once the home is lived in. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used.
It’s worth asking for a quote if you see:
- Sealant work across a run of new homes
- Sealant that never bonded to the surface
- Cracked sealant around new window and door frames
- Messy sealant that spoils new finishes
Golders Green is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Advice
Landlord and commercial work in Golders Green
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
