Sand mastic for homes and businesses in Wyke
Old sand mastic cracks, crumbles and falls out over time, leaving gaps round the window. We rake it out and renew it so the surround looks right again. We are often asked to deal with gaps round a timber door in stone or brick and mastic that needs renewing before redecorating, on tenement windows, sash and case windows and stone surrounds.
In a village or hamlet like Wyke, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
Big or small, it’s backed by our one-year guarantee in Wyke and across Surrey.

Questions from Wyke
Do you work for landlords with property near Ash station?
Yes. We work for landlords and letting agents as well as homeowners. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear quote.
Is Wyke within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
How long does sand mastic take?
Most jobs take anything from a few hours to a full day, depending on how many windows, including the preparation. We will confirm how long when we quote.
Where are you based?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
What exactly is sand mastic?
Sand plus a binder based on linseed oil. It’s applied by hand and finished to sit neatly against the masonry.
Can I do it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
How much does sand mastic cost in Wyke?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we will talk you through it.
DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Do not paint over the new mastic
- Get any rot dealt with first
- Plan mastic work ahead of painting
- Keep modern sealant off the mastic
Do not touch or press the mastic while it hardens. It skins over quickly but needs longer to fully harden.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.
Wyke homes and the weather
Historic houses like Wanborough Manor (about 2.2 miles south-east) are a reminder that the area around Wyke has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you live in an older home near Church of St Peter, frames set in older brick or stone need a sealant that suits the wall as well as the frame. For site and facilities teams at buildings such as Wyke Primary School, the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near Ash station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

What the job involves on each surface
Sash and case windows
On a sash window, the mastic joint shows on the outside, so a neat, even finish matters.
Brick reveals
Gaps between frame and brick let in rain and draughts. New mastic seals the gap.
What happens on the day
Before we leave, we go over the finished joints with you. The visit itself generally takes a few hours for a single window, longer for several, depending on how much there is to do. In a small place like Wyke, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic is not too thick.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
How to prepare
- Keep pets and children clear of the area while we work
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any water getting in

What happens if it’s left?
Filling over old, loose mastic doesn’t last. Raking out and preparing the joint gives it a sound base so the new work lasts. Around Wyke, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
