How we handle new build mastic in Beckton
For builders and developers, we work through plots to the schedule you give us. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over. If you are dealing with plot mastic for developers ahead of handover and cracked caulk along new skirting, we can help, whatever the surface.
New flats are going up across London, many of them in larger developments. In a new development, snags are often reported through the developer or the managing agent, and failed shower seals, open skirting joints and gaps at thresholds are typical.
We stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

Beckton: your questions answered
Do you cover Beckton for new build mastic?
Yes, Beckton is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or send us an email and tell us what needs doing.
Is parking a problem for a job in Beckton?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
Is there any odour?
There can be a smell while the sealant cures. Opening a window helps.
Can you match the sealant colour to my new kitchen or bathroom?
White and clear are the most common, but other colours are available. We match the colour to the finish before we begin.
Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Where are you based?
We’re a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Are you fully insured?
Yes. Full insurance covers our work.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Aftercare tips
Aftercare is simple:
- Ventilate bathrooms well, especially in the first year
- Raise failed sealant with the developer while you’re covered
- Photograph failed sealant before it’s redone
- Clean sealant with mild detergent, not abrasives
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing.
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 sealant work can’t fix
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Deciding who is responsible under a builder’s warranty
- Structural cracks in walls or ceilings
- A tray or bath that isn’t properly supported, until it’s fixed
If you’re not sure, just phone 0345 464 0079 or email us and we will give you a straight answer before you book.

How it works
We bring everything the job needs with us, so there’s nothing for you to buy. Once we’ve agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours for most snagging lists, longer for a run of plots. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Beckton. It helps if you can point us to a visitor permit or a bay close to the door.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
Getting ready for the visit
- For business premises, tell us about site rules or sign-in
- Plan for the work area to be out of bounds to pets and children
- Mention if the joints have been sealed before

Advice
How the job changes by surface
Skirting and floors
Wet-area floor joints need a flexible seal. We seal them with a sealant suited to wet areas.
Kitchens
New-kitchen sealant is often applied in a rush. We take it out and reseal neatly, colour-matched where it shows.
Can I do it myself?
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 doesn’t work out, we can still put it right.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Why deal with it now?
The builder is normally the first port of call while the snagging or warranty period runs. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Beckton, the repair is bigger than a sealant job.
What it costs depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.

Joints and finishes in Beckton homes
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 snagging may go through the developer or managing agent.
If you’ve bought a new home near Woolwich station, the sealant around baths, showers and frames is worth checking in the first year or two. Beckton is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
