New build mastic in Barkingside
Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover. We’re often asked to deal with messy sealant that spoils new finishes and shower seals failing in the first year or two, on bathrooms & en suites, show homes and windows & doors.
Shops, offices and commercial units across London have hard-wearing floors with movement joints that need resealing as they wear, and new homes need their plot mastic finished properly before handover.
There’s a 12-month guarantee on every job, large or small.

The process
We keep the work tidy and contained to the area we’re working on, so you can carry on as normal. Expect the work to take a few hours in a single home, and we tell you how long to leave it before we go. For a job in Barkingside, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
How to prepare
- Mention if the joints have been sealed before
- Clear the area around the work
- Let us know if you’ve seen damp or leaks

Why act early in Barkingside
Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time and most come down to preparation. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and agree the price before starting.
Why Barkingside clients choose us
- White, clear, grey or coloured to suit, where the product allows

Barkingside questions
Do you work for landlords with property near Seven Kings station?
Yes. We work for letting agents and landlords as well as householders. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Can you do new build mastic in Barkingside?
Yes. We work across London and the South East, and Barkingside is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear quote.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll tell you what we are using.
Is it messy?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Is it worth resealing while the house is still settling?
If the seal has failed and water is getting in, do it now. Small gaps that are just cosmetic can be resealed once movement has slowed.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
My new home is still under warranty. Should I contact you?
Report it to the builder first while you’re covered. If it isn’t resolved, we can reseal it properly.
Common problems we fix in Barkingside
New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. As it does, timber shrinks and joints open, and sealant that cannot keep up splits.
Look out for these signs:
- Cracked caulk along new skirting
- Smeared, uneven beads picked up at snagging
- Cracked sealant around new window and door frames
- New-build shower sealant that has already split
If you’ve bought a new home near Seven Kings station, the sealant around baths, showers and frames is worth checking in the first year or two.

Quotes for new build mastic in Barkingside
We quote each job individually. This is what makes a difference:
- The number and length of the joints
- How easy the joints are to reach

What we need to know
You don’t need to know the technical terms. It helps if you can tell us:
- If someone has resealed it before
- The rough size of the job
- How we’d reach the joints
- Where the job is, and your postcode
If you’re in Barkingside and need new build mastic, phone 0345 464 0079 or email us. A short description of the job and where it is helps us quote, and we will agree the price before any work begins.
What sealant work can’t fix
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Leaks from pipes, valves or wastes, which need a plumber
- Your warranty claim itself, which is between you and the builder
- Structural cracks in walls or ceilings
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly.
What we seal
- Windows & doors
- Skirting & floors
- Plot handovers
- Kitchens
- Show homes
- Bathrooms & en suites
Different surfaces, different methods
Show homes
Tired or marked sealant in a show home can be renewed. We cut it out and reseal neatly.
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. Resealing properly keeps water where it belongs.
For landlords and businesses
Hotels need rooms back in use, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.
New homes and floors in Barkingside
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.
Barkingside is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
