New build mastic in North Street
Some new-home owners let the house settle before resealing. For small cosmetic gaps, that’s reasonable, but a failed shower or bath seal shouldn’t wait. We work on show homes, kitchens and bathrooms & en suites, and people most often call us about skirting joints opening in the first winter and untidy sealant flagged on a snagging list.
In a village or hamlet like North Street, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
All our work comes with a 12-month guarantee.

What to tell us for a quote

When to call us in North Street
Sealant is often one of the last jobs before handover. Dusty, unprimed joints are common, and the sealant sits on grit instead of the surface.
Common reasons people contact us are:
- Gaps behind new kitchen upstands
- Leaking shower tray seals in a new home
- Gaps opening as the house dries out and settles
- Gaps between new skirting and floors
In and around North Street, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

What happens if it’s left?
It often makes sense to do all the sealant items on a snagging list together. You get one visit and one clear quote for the lot. Older cottages and farmhouses around North Street can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, phone 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

DIY sealant or a professional job?
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 doesn’t work out, we can still put it right.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
How the job changes by surface
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. The joint is stripped back before the new bead goes in and baths are filled before sealing.
Kitchens
Worktops in new homes can move slightly as the house dries, which opens gaps along the back. A fresh flexible bead closes them.

Your questions about new build mastic in North Street
What guarantee comes with new build mastic in North Street?
All our work, in North Street and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Is North Street within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Is it normal for sealant to crack in a new home?
Lots of new homes see sealant crack early, because the house is drying and settling. Poor preparation at handover adds to it.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Can landlords and businesses book you?
Yes, we do. We work in homes, commercial premises and hotels.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
Are you fully insured?
Yes. We’re fully insured, and we can confirm the details when we quote.
