Why deal with it now?
A silicone bead can be quicker, but it can look wrong on a period surround. Sand mastic is the traditional material and blends with the stone or brick. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Kensal Town, the repair is bigger than a sealant job.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.

Sand mastic for homes and businesses in Kensal Town
If your home is listed or in a conservation area, check with your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. We work on period & listed homes, timber door frames and tenement windows, and the jobs we see most are draughty sash windows at the surround and old cement repairs round a window that have failed.
Many London homes are flats, with windows high above the street. Who looks after the outside of the frames can depend on the lease, so check that first, and access in Kensal Town is something to talk through when you book.
You are covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

What sand mastic looks like in Kensal Town
In a converted house or block, who looks after the windows depends on the lease, so it’s worth checking before booking. With historic houses such as Kensington Palace (about 1.6 miles south-east) nearby, there’s older building stock in the area around Kensal Town as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
For landlords with property near Queens Park (London) station, any sash windows need sound mastic to keep draughts and rain out. For site and facilities teams at buildings such as St Thomas' CofE Primary School, larger buildings have plenty of frames, and the mastic around each one ages. As a London address, Kensal Town can be tricky for parking: let us know about parking bays, permits or a driveway.

Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Sort the mastic before the decorators arrive
- Have rotten timber repaired before new mastic goes in
- Take care around the mastic when scraping paint
- Look over the window mastic once a year
When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens as more mastic falls out.
