About our new build mastic in Canons Park
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. We work on windows & doors, show homes and skirting & floors, and people most often call us about frame joints opening as the plaster dries and sealant applied over dusty or wet surfaces.
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.
Whatever the size of the job, it’s backed by our one-year guarantee in Canons Park and across Greater London.

Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Honest limits
A few problems are outside what sealant work can do:
- Plumbing faults behind the sealant
- Baths and trays that move too much for sealant to cope with
- Broken tiles or a split tray

Common questions in Canons Park
Is parking an issue for new build mastic in Canons Park?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.
Do you cover Canons Park for new build mastic?
Yes. Our work covers London and the South East, and Canons Park is part of that. You can phone 0345 464 0079 or email us and tell us what needs doing, and we’ll give you a clear price.
Are you an approved applicator?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Should I go to my builder first?
Start with your builder while their snagging or warranty period runs. If that does not work out, we’re happy to quote and our work is guaranteed for a year.
Is it worth resealing while the house is still settling?
Where water is getting through, don’t wait. Hairline cosmetic gaps can wait until the house has settled.
Do you use white or clear sealant?
Most bathroom joints are white or clear, but other colours are available. We match the colour to the finish and agree it with you.
Does someone need to be in?
That depends on where the joints are. Inside work needs someone to give us access.
What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
When to call us in Canons Park
Not every new-build joint gets the right sealant: caulk where water collects, or a rigid product on a moving joint. Both fail early.
Keep an eye out for these signs:
- Kitchen sealant that has pulled off the wall
- Beads laid onto grit and dust from the build
- Plot mastic for developers ahead of handover
- Untidy sealant flagged on a snagging list
For new homes near Mill Hill Broadway station, it’s worth checking the sealant early, while snags are still fresh.

Joints and finishes in Canons Park homes
Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Canons Park is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
Canons Park is about 1 mile east of Stanmore, in Greater London. Jobs in Canons Park get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee. Our Greater London coverage runs to 764 places, Canons Park among them. There’s also a page for London, roughly 11 miles from Canons Park.
Here we cover the HA8 and HA7 postcode area for new build mastic. You’ll find streets such as Parr Road, Mead Road and Grove Road. We also cover Little Stanmore (1 mile south-east), Edgware (1 mile north-east), Burnt Oak (1 mile east), Broadfields Estate (1 mile north-east) and The Hale (1 mile north-east). We also work in nearby towns such as London (11 miles south-east), City of Westminster (9 miles south-east), Marylebone (9 miles south-east), Kensington (8 miles south-east), St Pancras (9 miles south-east) and Shoreditch (11 miles south-east).
Around Canons Park
Typical jobs here are in homes near Edgwarebury Park, Railway Hotel and Krishna Avanti Primary School and the streets around them. For rail, the closest station is Mill Hill Broadway station, about 1.7 miles east. A little further out are Hilfield Castle (3.7 miles north-west) and Broadwalk Centre (0.6 miles east). Open spaces near Canons Park include Edgware Way Grassland and Darland's Lake.
What happens if it’s left?
A tube of sealant from the DIY shop won’t fix the cause: dust, no primer and old sealant left in the joint. Cutting out, cleaning and priming are what make the difference. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Canons Park, 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. Call for a quick quote and we’ll explain what it covers.

What the job involves on each surface
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
Skirting and floors
Gaps under skirting are one of the most common new-build snags. A flexible sealant closes it without cracking like caulk.
