New build mastic in North Street
Dust is the enemy of new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the new bead bonds properly instead of bonding to the dust. If you are dealing with sealant that never bonded to the surface and second-fix sealing on new plots, we can help, whatever the surface.
Somewhere as small as North Street, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
There’s a 12-month guarantee on every job, whatever its size.

Leave it or put it right?
Small cosmetic gaps can wait for the house to settle, but water getting through can’t. Not sure whether yours can wait? You can ring 0345 464 0079 or drop us an email with a few pictures and we’ll give you a straight answer. Where a wall is exposed, as many are in small places like North Street, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Leaving a failed joint normally makes the job bigger, not smaller. If you are unsure, call 0345 464 0079 or send us an email for an honest opinion and a quote.

Can I do it myself?
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, then guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Common problems we fix in North Street
If plaster or screed was still damp when it was sealed, the bond suffers. Site programmes do not always leave time for joints to dry before the sealant goes on.
It’s worth asking for a quote if you see:
- Kitchen sealant that has pulled off the wall
- Beads laid onto grit and dust from the build
- Gaps opening as the house dries out and settles
- Leaking shower tray seals in a new home
Around North Street, as everywhere, new build mastic is only as good as the preparation behind it.

How the job changes by surface
Skirting and floors
Floors and skirting move as the house dries and the heating runs. Caulk cracks; a flexible sealant moves with it painted or coloured to suit.
Plot handovers
Good preparation at handover saves snagging later. We clean out building dust before sealing and prime where the product needs it.
Joints and finishes in North Street homes
North Street is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. 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.
If you’ve bought a new home near Gillingham (Kent) station, the sealant around baths, showers and frames is worth checking in the first year or two.

North Street: your questions answered
Is North Street within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you do new build mastic in North Street?
Yes. Our work covers London and the South East, and North Street is part of that. Just ring 0345 464 0079 or email us with a few details of the job.
Why has my new-build shower seal failed already?
It’s common, and there are usually two reasons: movement as the house dries and settles, and sealant laid onto dust without primer. A proper reseal deals with both.
I’m a tenant. Can you help?
We’re happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before resealing.
Is it messy?
No. The area is protected while we work and cleaned up afterwards.
Do you work through snagging lists?
Yes. Snagging lists are a common starting point for us. We’ll go through the sealant items and agree what we’ll do.
Where are you based?
Our base is Crawley. We work across South East England, London and Scotland.
How it works
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on.

Everything for the job comes with us, so a second trip is avoided where possible.
