Jenkins' Green Sand Mastic
Sand mastic in Jenkins' Green from a team with over 20 years’ experience. Rated 4.9 on Google from 180+ five-star reviews.
- Mastic dropping out of the joint
- Window mastic to renew ahead of painting
- Weathered mastic on the most exposed windows
Looking after it afterwards
To keep the joints looking good and working properly:
- Renew mastic before redecorating the windows
- Don’t paint over the new mastic
- Keep sills and gutters clear so water drains away
- Get any rot dealt with first
Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens.
Sand mastic for homes and businesses in Jenkins' Green
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s made from sand and a linseed-oil-based binder and built up by hand. On older homes, it suits the building far better than silicone. We work on period & listed homes, sash and case windows and tenement windows, and common reasons people get in touch are open joints round the window box and modern sealant on a period surround.
In a village or hamlet like Jenkins' Green, 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.
There’s a 12-month guarantee on every job, whatever its size.

Jenkins' Green: your questions answered
Will you come out to Jenkins' Green?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Is sand mastic in a coastal place like Jenkins' Green any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Should I use sand mastic or silicone?
We’ll talk it through with you. Period homes often look best with sand mastic and newer frames suit modern sealant.
Where are you based?
Our base is Crawley. Our area covers South East England, London and Scotland.
Is it OK to seal over old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
What do you need from me for a quote?
The location, the problem and the rough size of the job. If you can, email a few pictures.
How do I get a quote for sand mastic in Jenkins' Green?

DIY versus a professional finish
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Why act early in Jenkins' Green
Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic is the traditional material and blends with the stone or brick. Older cottages and farmhouses around Jenkins' Green can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and agree the price before starting.

Windows and doors in Jenkins' Green
Jenkins' Green is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around St Luke's Church, the joint between an old wall and a newer frame is generally the first place rain gets in. Schools such as Hankham Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. Rented homes near Pevensey & Westham station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.
