About our new build mastic in Broom Hill
Dust is the enemy of new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the sealant actually sticks. If you are dealing with sealant that never bonded to the surface and sealant work across a run of new homes, we can put it right.
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 Broom Hill and beyond.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

New homes and floors in Broom Hill
Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent. 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.
As a London address, Broom Hill can be tricky for parking: let us know about parking bays, permits or a driveway.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Avoid scourers and strong chemicals on sealant
- Open a window or run the fan after bathing
- Photograph failed sealant before it’s redone
- Don’t seal over failed sealant yourself
Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it, which can damage the surface.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak over time.
Common problems we fix in Broom Hill
If plaster or screed was still damp when it was sealed, the bond suffers. On a busy site, joints aren’t always given time to dry before the sealant goes on.
The problems people normally mention when they call include:
- Gaps between new skirting and floors
- Untidy sealant flagged on a snagging list
- Second-fix sealing on new plots
- Cracks appearing as a new home settles
For new homes near Orpington station, it’s worth checking the sealant early, while snags are still fresh.
What your quote should include
- How the joint is cleaned and prepared
- Whether they seal over old material or remove it

- When the joint can take water or movement
How we quote for new build mastic
The quote reflects the job in front of us. We look at:

What to tell us for a quote
You don’t need to know the technical terms. It helps if you can tell us:
- If someone has resealed it before
- Pictures of the joints, sent by email
- Whether it’s a home or a business
- How we’d reach the joints
We quote each job on its own. Simply ring 0345 464 0079 or drop us an email and describe the job.
DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We cut it out and start again.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
When something else is needed
We’ll always be straight with you, so here’s what new sealant will not do:
- Broken tiles or a split tray
- Movement caused by a poorly fitted tray or bath
- Structural cracks in walls or ceilings
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think.
What we seal
- Plot handovers
- Skirting & floors
- Bathrooms & en suites
- Kitchens
- Windows & doors
- Show homes

What else we do in Broom Hill
Different surfaces, different methods
Skirting and floors
New homes often develop a gap between skirting and floor. A flexible sealant closes it without cracking like caulk.
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We cut out the cracked bead and reseal with a flexible sealant in a matching colour.
