About our sand mastic in Rackham
Sand mastic doesn’t last for ever, leaving gaps round the window. Renewing it closes the gap and tidies the surround. We are often asked to deal with mastic round period door frames that has failed and a silicone bead on a sash window that spoils the look, on brick reveals, tenement windows and sash and case windows.
Somewhere as small as Rackham, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
Each job carries a 12-month guarantee, whatever its size.

How the visit works
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. It normally takes a few hours per window, depending on the condition of the joints. Somewhere as small as Rackham, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each surround is checked first.
- The joint is raked out and cleaned.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.

Do you need sand mastic in Rackham?
Most of it is simply age. Sand mastic is a maintenance item like any pointing and how long it lasts depends on the weather it faces.
Look out for these signs:
- Cracked mastic round a front door frame
- Draughty sash windows at the surround
- Mastic dropping out of the joint
- Gaps where the frame meets the masonry
If you live in an older home near Church of St Peter, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Why it’s worth doing now in Rackham
A silicone bead can be quicker, but on period stone or brick it often looks out of place. Sand mastic suits the building and finishes neatly against the masonry. Around Rackham, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Rather than a set price list, 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 book with us
- Every job guaranteed for a year
- Arbo and Everbuild products
- Anti-fungal sanitary silicone in wet areas
- We leave the area clean and tidy

Frames and glazing around Rackham
Historic houses like Parham House (about 0.7 miles north-east) are a reminder that the area around Rackham has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Should I try it myself first?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
