New build mastic in Brent Cross
New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, and sealant applied in a hurry at handover can split. If you are dealing with untidy sealant flagged on a snagging list and internal frame sealant that has split, we can put it right.
Shops, offices and commercial units across London have hard-wearing floors with movement joints that need resealing as they wear, while new homes need a neat, sound finish around frames, baths and kitchens before handover.
Each job carries a 12-month guarantee, large or small.

What the job involves on each surface
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We cut out the cracked bead and reseal with a flexible sealant.
Skirting and floors
As timber and screed dry, skirting and floors shift. Caulk cracks; a flexible sealant moves with it painted or coloured to suit.
New homes and floors in Brent Cross
Many of London’s new homes are flats in bigger developments, where snagging may go through the developer or managing agent. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For new homes near Brent Cross West station, it’s worth checking the sealant early, while snags are still fresh.

How we quote for new build mastic
The quote reflects the job in front of us. We take into account:
- Working hours on commercial sites
- Mould in or behind the old joints
- Whether old sealant or filler has to be cut out
- How many areas need sealing
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.
Asking for a quote
Before you ask for a quote, have a think about:
- The rough size of the job
- The problem you’ve noticed
- Any previous sealing or DIY work
- Where the job is, and your postcode
We do not publish a price list, as no two jobs are quite the same. Instead, we give you a clear quote for your job. To get started, phone 0345 464 0079 or email us.

How to look after the new joints
So the new joints stay in good condition:
- Watch for new gaps as the house dries out
- Wipe joints with warm soapy water
- Open a window or run the fan after bathing
- Report sealant problems to your builder during the snagging period
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries.
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 we do, step by step
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours in a single home. In a London area like Brent Cross, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- Each joint is checked for movement before work begins.
- We remove the failed sealant and clean the joints.
- 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.
- The finished joints are checked and the cure times given.
Preparing for the visit
- Mention if the joints have been sealed before
- Plan for the work area to be out of bounds to pets and children
- On commercial sites, let us know about site rules

Related advice
Do you need new build mastic in Brent Cross?
A new house holds a lot of water from the build, which takes a year or two to dry out. Drying timber shrinks and pulls joints apart.
If you can see any of these, it’s time to have the joints looked at:
- Leaking shower tray seals in a new home
- Sealant that never bonded to the surface
- Smeared, uneven beads picked up at snagging
- Cracks appearing as a new home settles
As a London address, Brent Cross can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Will the old sealant be removed?
Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.
