What is sand mastic?
It’s the traditional filler for the joint round timber windows and doors. It’s made with sand and a linseed-oil-based binder.
Will there be a smell?
That depends on the sealant. Some products have a noticeable smell, others very little.
What does sand mastic cost?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Is it worth trying it myself?

Is the work guaranteed?
All our work has a one-year guarantee.
Can you match the sealant colour?

What sand mastic looks like in Cadmore End
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as West Wycombe Park House (about 2.8 miles east) nearby, there’s older building stock in the area around Cadmore End as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
For an older house near a landmark such as Church of St Mary Le Moor, frames set in older brick or stone need a sealant that suits the wall as well as the frame. If you look after a building such as Cadmore End CofE School, the mastic around its windows and doors needs looking after like any other building’s.

What affects the cost of sand mastic
Your quote is based on your job. We look at:
- How easy the joints are to reach
- Working hours on commercial sites
- The product the joint needs
- Mould in or behind the old joints
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference.
What to tell us for a quote
When you call or email, it’s useful to know:
- How many joints, rooms or windows are involved
- Where the job is, and your postcode
- What the problem is, such as mould, gaps, leaks or cracking

Why it’s worth doing now in Cadmore End
New mastic over crumbling mastic will not hold. Raking out and preparing the joint gives it a sound base so the new work lasts. In a small place like Cadmore End, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or send us an email.
