Sand mastic in Hoe Gate, done properly
If your home is listed or in a conservation area, check with your local planning authority if consent is needed before window work. Sand mastic is often favoured as a like-for-like material. We work on sash and case windows, period & listed homes and stone surrounds, and the jobs we see most are wind and rain getting in round a sash window and old sand mastic that has cracked, crumbled or fallen out.
In a village or hamlet like Hoe Gate, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
Our work is backed for twelve months.

Why act early in Hoe Gate
Filling over old, loose mastic does not last. Raking out and preparing the joint gives it a sound base so the new work lasts. Around Hoe Gate, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, phone 0345 464 0079 or send us an email for an honest opinion and a quote.

Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Ask a joiner to look at soft timber first
- Leave the new mastic unpainted
- Renew mastic before redecorating the windows
- Go gently near the mastic when preparing windows
Avoid sealing over the mastic with silicone. If anything cracks, get it looked at rather than patching it.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber, which can lead to rot.
What sealant work cannot fix
In fairness, there are a few things sealant won’t fix:
- Damaged stone surrounds
- Sashes that rattle, stick or won’t open
- Putty and glazing repairs

Do you need sand mastic in Hoe Gate?
Paint, silicone or cement used over old mastic causes problems. They do not move with the timber, and they usually need raking out.
The most common problems we see are:
- Weathered mastic on the most exposed windows
- Cement or filler used on old window joints that has cracked
- Tired mastic found when preparing windows for paint
- Mastic round period door frames that has failed
Homes close to Church of the Holy Trinity include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in.
Questions to ask before booking
- What happens if they find a problem under the old sealant
- What insurance they hold
- How much experience the applicator has
- When the joint can take water or movement
What we do, step by step
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours for a single window, longer for several, and the area is left clean. Somewhere as small as Hoe Gate, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- Deep voids are packed so the mastic is the right thickness.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
