Sand mastic in Compton, done properly
Across Compton, we renew sand mastic around sash and case windows. Each joint is raked out, prepared and pointed by hand for a neat, traditional finish. We work on tenement windows, sash and case windows and timber door frames, and common reasons people get in touch are a silicone bead on a sash window that spoils the look and draughts and rain around sash boxes.
Around Compton, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
Every job is covered by a one-year guarantee, wherever you are in Surrey.

When to call us in Compton
Age is the main cause. Sand mastic is a maintenance item like any pointing and how long it lasts depends on the weather it faces.
Look out for any of the following:
- Old sand mastic that has cracked, crumbled or fallen out
- Cracked mastic round a front door frame
- Window mastic to renew ahead of painting
- Weathered mastic on the most exposed windows
If you look after a building such as South Farnham School, larger buildings have plenty of frames, and the mastic around each one ages.
What your quote should include
- Whether they’re fully insured
- When the joint can take water or movement
- What product goes in the joint
- How the colour is chosen
Sand mastic in Compton: local notes
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. With historic houses such as Farnham Castle (about 1.8 miles west) nearby, there’s older building stock in the area around Compton as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you let a flat or house near Farnham station, cracked sand mastic around sash windows lets in the draughts tenants complain about. For an older house near a landmark such as St Marys Parish Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What we do, step by step
On the day, we look over the joints with you first, so you know exactly what we’re doing. We protect the surfaces around the joints before we start. Most jobs take a few hours for a single window, longer for several. Somewhere as small as Compton, access is often the only tricky part. 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.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
Before we arrive
- Mention any parking rules near the property
- Where the joints are inside, avoid wetting them before we arrive
- For business premises, tell us about site rules or sign-in

Advice
Can I do it myself?
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 fails, we can still redo it.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Different surfaces, different methods
Period and listed homes
Period homes look their best with traditional materials.
Timber door frames
Doors face weather and wear and the mastic can crack early. We rake it out and renew it.
