FAQs for Whitton
Is parking an issue for new build mastic in Whitton?
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.
Do you cover Whitton for new build mastic?
Yes. We work across London and the South East, and Whitton is part of that. You can call 0345 464 0079 or send us an email and tell us what needs doing, and we will give you a clear quote.
Can tenants book the work?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
How long should I leave it?
It depends on the product and the conditions. We tell you how long to leave it before we go.
What information do you need?
Just the basics: where it is, what you’ve noticed and how we reach it. Then phone 0345 464 0079 or send us an email.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status, and we are fully insured.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
How we handle new build mastic in Whitton
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. While the builder’s snagging or warranty period runs, report it to them first and if that stalls, we can do it. If you have gaps behind new kitchen upstands and sealant that never bonded to the surface, we can put it right, whatever the surface.
New flats are going up across London, many of them in larger developments. Snagging there often goes through the developer or managing agent, and failed shower seals, open skirting joints and gaps at thresholds are typical.
There’s a 12-month guarantee on every job, large or small.

DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Surface by surface
Skirting and floors
Wet-area floor joints need a flexible seal. They get a flexible, water-resistant sealant.
Windows and doors
Draughts around new frames are often a sealant gap. We look at the joints and reseal where needed.
The process
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for most snagging lists, longer for a run of plots and we leave things clean and tidy. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about any water getting in
- Clear the area around the work

Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Use the extractor fan every time you shower
- Act quickly if a seal starts to leak
- Photograph failed sealant before it’s redone
- Report sealant problems to your builder during the snagging period
Do not stand on the bath edge or the lip of the tray in the first few weeks. Report any movement in a bath or tray.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant.
