About our new build mastic in Bickley
Building dust is behind a lot of failed new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the new bead bonds properly. We work on kitchens, bathrooms & en suites and windows & doors, and the jobs we see most are cracks appearing as a new home settles and leaking shower tray seals in a new home.
Across London, commercial floors have movement joints that break down under heavy foot traffic, and new homes need their plot mastic finished properly before handover, in Bickley and beyond.
We stand behind the work with a one-year guarantee, so you’re covered after we’ve gone.

What we are called out for in Bickley
If plaster or screed was still damp when it was sealed, the bond suffers. On a busy site, joints aren’t always given time to dry.
The problems people usually mention when they call include:
- Internal frame sealant that has split
- Messy sealant that spoils new finishes
- Sealant work across a run of new homes
- Sealant that never bonded to the surface
If you’ve bought a new home near Bickley station, the sealant around baths, showers and frames is worth checking in the first year or two.

Questions from Bickley
Is parking an issue for new build mastic in Bickley?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Can you help a landlord with a rental near Bickley station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
How long does the job take?
A typical job takes a few hours for most snagging lists, longer for a run of plots, including the preparation. Your quote will say how long we expect yours to take.
Do you take on second-fix sealing for builders?
Yes. We seal plots to the developer’s programme ready for handover. Get in touch with the number of plots and the scope for a clear quote.
When is the best time to reseal in a new build?
That depends on the joint. Failed seals in wet areas need doing now, but cosmetic gaps can wait for movement to slow.
Should I try DIY first?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
What should I tell you?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply phone 0345 464 0079 or drop us an email.
New build mastic in Bickley: local notes
Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Different surfaces, different methods
Kitchens
Beside the sink, the joint takes water every day. We use a sealant suited to kitchens.
Skirting and floors
Wet-area floor joints need a flexible seal. We seal them with a sealant suited to wet areas.
The process
The work is kept neat and contained to the joints we’re treating, so you can carry on as normal. The job usually takes a few hours for most snagging lists, longer for a run of plots. In Bickley, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely, with no layer left behind.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Tell us about any previous sealing or DIY attempts
- Try not to wet indoor joints just before the visit

Related advice
What happens if it’s left?
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Resealing promptly protects the new finishes around it. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Bickley, the repair is bigger than a sealant job.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.
