About our sand mastic in Horseman Side
Sand mastic skins over fairly quickly but full hardening takes longer. Traditionally, sand mastic is left unpainted, so ask us before you decorate. We work on sash and case windows, period & listed homes and stone surrounds, and people most often call us about a silicone bead on a sash window that spoils the look and gaps where the frame meets the masonry.
Mastic can only go onto a dry, clean joint, so window work in Horseman Side is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
There’s a 12-month guarantee on every job, large or small.

Why act early in Horseman Side
An open joint round the frame lets weather in. Left, water can reach the timber and the wall, so dealing with it now protects both. Older cottages and farmhouses around Horseman Side can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please phone 0345 464 0079 or drop us an email.

Landlord and commercial work in Horseman Side
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can go on one quote.
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
When something else is needed
A few problems are outside what sealant work can do:
- Broken panes
- Sashes that rattle, stick or will not open
- Planning or listed building consent (your local planning authority decides)
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly.

We bring what the job needs, so it can be finished in one trip where possible.

Aftercare tips
After the cure time, these simple habits help:
- Go gently near the mastic when preparing windows
- Keep modern sealant off the mastic
- Leave the new mastic unpainted
- Look over the window mastic once a year
Make sure water drains away from the window surround. Constant wetting wears the mastic faster.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
Common problems we fix in Horseman Side
Over the years, sand mastic weathers. It hardens, cracks and starts to come away on the stone or timber.
These are the problems we are asked about most:
- Mastic dropping out of the joint
- Patchy fillers round a sash window
- Tired mastic found when preparing windows for paint
- Failed mastic on an exposed elevation
Homes close to Church of St Paul include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in.

What sand mastic looks like in Horseman Side
With historic houses such as Hill Hall (about 4.2 miles north-west) nearby, there’s older building stock in the area around Horseman Side as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you let a flat or house near Brentwood station, older sash windows in a rental need their mastic kept sound to keep the weather out. Schools such as Drapers' Academy are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.
