About our new build mastic in De Beauvoir Town
New homes move as they dry out. Timber shrinks, plaster dries and baths and trays bed down, so sealant that was laid quickly before handover often cracks. Typical jobs include cracked caulk along new skirting and sealant work across a run of new homes, across windows & doors, plot handovers and kitchens.
London homes range from new-build flats to period conversions with new floors laid over old boards. Wherever a floor meets a wall, a skirting or a threshold, the joint has to allow for movement, in De Beauvoir Town as anywhere.
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.

Advice
What new build mastic looks like in De Beauvoir Town
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.
As a London address, De Beauvoir Town can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

De Beauvoir Town questions
Is parking a problem for a job in De Beauvoir Town?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Is De Beauvoir Town in your area for new build mastic?
Yes. Our work covers London and the South East, and De Beauvoir Town is part of that. Just phone 0345 464 0079 or email us with a few details of the job.
How long should I leave it?
It depends on the product and the conditions. Before we leave, we’ll tell you the cure time.
What colour sealant will you use?
That depends on what the joint meets: white or clear for most sanitary joints, colours for worktops, floors and frames. We agree the colour before work begins.
What information do you need?
The location, the problem and the rough size of the job. Photos by email help too.
Do you work for letting agents?
Yes, we do. We work in homes, commercial premises and hotels, and we’re fully insured.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
When is the best time to reseal in a new build?
If the seal has failed and water is getting in, do it now. Hairline cosmetic gaps can wait until the house has settled.
When something else is needed
We won’t take on work that won’t last, so here’s what sealant cannot put right:
- Your warranty claim itself, which is between you and the builder
- Leaking fittings rather than failed sealant
- Settlement cracks that need a surveyor
If you are not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer before you book.
Surfaces we seal
- Windows & doors

Why deal with it now?
It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times to plan around. In a flat in De Beauvoir Town, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first and send you a clear quote before work begins.
Why us?

- White, clear, grey or coloured to suit, where the product allows

What we’re called out for in De Beauvoir Town
Later trades and the final clean can damage fresh sealant. If it’s disturbed before curing, the joint can be left weak.
The problems people usually mention when they call include:
- Untidy sealant flagged on a snagging list
- Frame joints opening as the plaster dries
- Gaps between new skirting and floors
- Leaking shower tray seals in a new home
If you’ve bought a new home near Dalston Junction station, the sealant around baths, showers and frames is worth checking in the first year or two.
Before booking anyone
- Whether they seal over old material or remove it
- Are they insured?
- Is VAT in the price?
- What preparation is included
DIY versus a professional finish
If you’re set on DIY, put the effort into 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.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Landlords, agents and businesses in De Beauvoir Town
In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
