About our sand mastic in Snaresbrook
Our applicators renew the sand mastic around sash and case windows and doors set in stone or brick. The old mastic is raked out, and new mastic is applied and shaped by hand. Common call-outs are for old cement repairs round a window that have failed and gaps round a timber door in stone or brick, across timber door frames, tenement windows and period & listed homes.
London has a lot of flats and conversions, where windows are often on upper floors. In a converted house or block, the lease usually says who is responsible for the windows, so it’s worth checking before booking, and access in Snaresbrook is something to talk through when you book.
You get a one-year guarantee, the same in Snaresbrook as everywhere else we work.

Why act early in Snaresbrook
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic suits the building and blends with the stone or brick. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble for homes in Snaresbrook.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Why us?
- Approved under the ARBOMaster scheme
- Anti-fungal silicone where joints get wet
- 20+ years of sealant experience
- We never seal over old sealant

Windows and doors in Snaresbrook
With historic houses such as Valentines Mansion (about 2.4 miles south-east) nearby, there’s older building stock in the area around Snaresbrook as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking.
Rented homes near Wood Street station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. In the older streets around Church of St Peter in the Forest, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.

What else we do in Snaresbrook
Common problems we fix in Snaresbrook
Previous repairs in cement or silicone often trap water or crack away. They do not move with the timber, and they generally need raking out.
The most common problems we see are:
- Mastic that needs renewing before redecorating
- Mastic round period door frames that has failed
- Cement or filler used on old window joints that has cracked
- Mastic worn away on windows facing the weather
As a London address, Snaresbrook can be tricky for parking: let us know about parking bays, permits or a driveway.

Looking after it afterwards
After the cure time, these simple habits help:
- Go gently near the mastic when preparing windows
- Clear gutters so water doesn’t pour onto the windows
- Find out about consent before window work on a listed home
- Get any rot dealt with first
Avoid sealing over the mastic with silicone. If anything cracks, get it looked at rather than patching it.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens as more mastic falls out.
DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
