New build mastic in Shooter's Hill, done properly
Across Shooter's Hill, we work for both new-home owners and the builders handing those homes over. Whether it’s one en suite or a run of plots, the method is the same: remove, clean, prime where needed, then a neat new bead. We’re often asked to deal with second-fix sealing on new plots and worktop and upstand sealant coming away, across plot handovers, skirting & floors and windows & doors.
Shops, offices and commercial units across London have hard-wearing floors with movement joints that need resealing as they wear, and new homes need their plot mastic finished properly before handover, in Shooter's Hill and beyond.
Your job is guaranteed for a year, as with all our work.

Can I do it myself?
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.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
When to call us in Shooter's Hill
Once people move in, baths and trays take weight and bed down. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used.
These are the problems we are asked about most:
- Cracks appearing as a new home settles
- Sealant that never bonded to the surface
- Gaps between new skirting and floors
- Worktop and upstand sealant coming away
As a London address, Shooter's Hill can be tricky for parking: let us know about parking bays, permits or a driveway.

What we can’t put right
We won’t take on work that won’t last, so these are the limits:
- Your warranty claim itself, which is between you and the builder
- Plumbing faults behind the sealant
- Baths and trays that move too much for sealant to cope with
If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think before you book.

Shooter's Hill questions
Can you do new build mastic in Shooter's Hill?
Yes. We work across London and the South East, and Shooter's Hill is part of that. You can phone 0345 464 0079 or email us and tell us what needs doing, and we’ll send you a clear quote.
Can parking be tricky for a visit in Shooter's Hill?
Parking in Shooter's Hill, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
What does new build mastic cost?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before work begins.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done.
Why does sealant fail so quickly in new builds?
It’s common, and there are usually two reasons: the house moving as it dries, and sealant that never bonded properly. A proper reseal deals with both.
What sealant do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we are using.
Do you work for landlords and businesses?
Yes. We work for homeowners, landlords, letting agents, businesses and hotels across Greater London.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures.
Landlord and commercial work in Shooter's Hill
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
In hotels, rooms out of use cost money, so we plan the work room by room. We have worked in hotels as well as homes and businesses.
New homes and floors in Shooter's Hill
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent.
If you’ve bought a new home near Falconwood station, the sealant around baths, showers and frames is worth checking in the first year or two.

What else we do in Shooter's Hill
What happens if it’s left?
A quick bead over the top of the old sealant can look fine at first, but it cannot bond to what’s underneath. A lasting seal starts with removing the old one completely. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Shooter's Hill, the repair is bigger than the sealant job would have been.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Call for a quick quote and we’ll go through it with you.
