Brompton: your questions answered
Can you do new build mastic in Brompton?
Yes. Our work covers London and the South East, and Brompton is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job.
Do you work for landlords with property near London Victoria station?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear price.
Do you use white or clear sealant?
That depends on what the joint meets: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We will agree it with you first.
Is there a guarantee?
Yes, for a year. If there’s a problem with our work in that time, tell us and we’ll put it right.
Will the old sealant be removed?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
When is the best time to reseal in a new build?
It depends on whether water is getting through. Failed seals in wet areas need doing now, but cosmetic gaps can wait for movement to slow.
What information do you need?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply phone 0345 464 0079 or send us an email.
Are you ARBOMaster approved?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
How we handle new build mastic in Brompton
Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover using the right product for each joint. Typical jobs include messy sealant that spoils new finishes and plot mastic for developers ahead of handover, on skirting & floors, plot handovers and kitchens.
Shops, offices and commercial units across London have hard-wearing floors with movement joints that need resealing as they wear, while new homes need a neat, sound finish around frames, baths and kitchens before handover, in Brompton and beyond.
You are covered for a year from the day we finish. If anything isn’t right with it, phone 0345 464 0079 or email us.

Landlord and commercial work in Brompton
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
We work for letting agents and landlords as well as householders. Resealing between tenancies keeps a property looking cared for.
Different surfaces, different methods
Kitchens
Beside the sink, the joint takes water every day. We use a sealant suited to kitchens.
Skirting and floors
As timber and screed dry, skirting and floors shift. Caulk cracks; a flexible sealant moves with it painted or coloured to suit.
When something else is needed
New sealant can’t fix everything, and we will tell you before work begins. It won’t solve:
- Cracking that points to a structural problem
- Your warranty claim itself, which is between you and the builder
- Baths and trays that move too much for sealant to cope with
If you’re not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer.
Joints and surfaces we work on
- Kitchens
- Windows & doors
- Show homes
- Plot handovers
- Skirting & floors
- Bathrooms & en suites
Looking after it afterwards
Looking after new joints is easy:
- Don’t wait for the house to settle if water is getting through
- Raise failed sealant with the developer while you are covered
- Wipe joints with warm soapy water
- Avoid running a DIY bead over the old one
Wipe the sealant with warm soapy water. Avoid abrasive pads and strong solvents as they wear the bead.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.

What happens if it’s left?
DIY kits don’t solve the main problems with new-build sealant: grit, unprimed surfaces and old layers underneath. Proper removal and preparation are what make it last. In a flat in Brompton, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we will go through it with you.

New build mastic around Brompton
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Many of London’s new homes are flats in bigger developments, where snags may need reporting through the developer or the managing agent.
As a London address, Brompton can be tricky for parking: let us know about parking bays, permits or a driveway. If you’ve bought a new home near London Victoria station, the sealant around baths, showers and frames is worth checking in the first year or two.
