New build mastic around Brimsdown

As a London address, Brimsdown can be tricky for parking: let us know about parking bays, permits or a driveway.

About our new build mastic in Brimsdown
Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover using the right product for each joint. Typical jobs include sealant that never bonded to the surface and cracked caulk along new skirting, across show homes, plot handovers and windows & doors.
From brand-new flats to converted terraces with new flooring, London has every kind of floor. Wherever a floor meets a wall, a skirting or a threshold, the joint has to allow for movement.
Every job is covered by a one-year guarantee, wherever you are in Greater London.

- Leaking shower tray seals in a new home
- Sealant applied over dusty or wet surfaces
For new homes near Brimsdown station, it’s worth checking the sealant early, while snags are still fresh.

Common questions in Brimsdown
Is parking a problem for a job in Brimsdown?
Parking in Brimsdown, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
I let a flat near Brimsdown station. Can you help?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear quote.
What information do you need?
The location, the problem and the rough size of the job. If you can, email a few pictures.
Can you do several jobs on one visit?
Yes. Just list everything you need and you will get one quote.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us.
Can you work from my snagging list?
Yes. Snagging lists are a common starting point for us. We’ll go through the sealant items and agree what we’ll do.
Should I try DIY first?
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.
Is the work guaranteed?
Yes. All our work carries a one-year guarantee.
Leave it or put it right?
It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times for the lot. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Brimsdown, the repair is bigger than a sealant job.
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.

How the job changes by surface
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. A proper reseal keeps water in the tray.
Skirting and floors
Gaps under skirting are one of the most common new-build snags. A flexible sealant closes it without cracking like caulk.
What we do, step by step
Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for most snagging lists, longer for a run of plots. For a job in Brimsdown, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Getting ready for the visit
- On commercial sites, let us know about site rules
- Tell us if parking is tricky
- Mention if the joints have been sealed before

Related advice
Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

What else we do in Brimsdown
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Wipe joints with warm soapy water
- Open a window or run the fan after bathing
- Watch for new gaps as the house dries out
- Keep water off fresh sealant until it has cured
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing.
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.
