How we handle sand mastic in Oak Corner
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant and we will explain which is best for yours. If you have gaps where the frame meets the masonry and patchy fillers round a sash window, we can help.
Somewhere as small as Oak Corner, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
Each job carries a 12-month guarantee, whatever its size.

Your questions about sand mastic in Oak Corner
Can you help a landlord with a rental near Thorpe-Le-Soken station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just phone 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear quote.
Does the coastal weather in Oak Corner affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
How long does the job take?
As a guide, most jobs take a few hours for a single window, longer for several. Larger jobs naturally take longer.
Do you remove the old sealant?
Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Can you quote for more than one area?
Yes. More than one area can be quoted together.
Do you come to Oak Corner?
Yes, we do. Our applicators work in Oak Corner.
Are you fully insured?
Yes, we are fully insured for domestic and commercial work.
What is sand mastic?
A traditional pointing material made from sand and a linseed-oil-based binder for the joint between timber frames and masonry.
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Oak Corner homes and the weather
Oak Corner is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around older windows and doors, especially on the side facing the sea. Historic houses like Thorpe Hall (about 2.4 miles south) are a reminder that the area around Oak Corner 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.
Rented homes near Thorpe-Le-Soken station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.

Why deal with it now?
Replacing sash windows is a big decision for a period home and on a listed home, consent may be needed. Where the frames are in good order, new mastic seals the surround. Older cottages and farmhouses around Oak Corner can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first.
Why us?

Signs you need sand mastic in Oak Corner
Age is the main cause. Sand mastic is a maintenance item like any pointing, depending on exposure and upkeep.
People generally contact us when they notice one of these:
- Draughty sash windows at the surround
- Old sand mastic that has cracked, crumbled or fallen out
- Silicone on a period window that looks wrong
- Tired mastic found when preparing windows for paint
In the older streets around Parish Church of St Leonard, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
