Sand Mastic in Peper Harow
Sand mastic across Peper Harow and nearby, with old sealant always removed completely.
- Mastic worn away on windows facing the weather
- Tired mastic found when preparing windows for paint
- Draughty sash windows at the surround
Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Get any rot dealt with first
- Don’t run silicone over sand mastic
- Sort the mastic before the decorators arrive
- Check with your local planning authority if your home is listed
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
Sand mastic for homes and businesses in Peper Harow
Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. Renewing it closes the gap so the surround looks right again. If you have old sand mastic that has cracked, crumbled or fallen out and mastic worn away on windows facing the weather, we can put it right, whatever the surface.
Around Peper Harow, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
Big or small, it’s backed by our 12-month guarantee in Peper Harow and across Surrey.

Why it’s worth doing now in Peper Harow
Before painting the windows, it pays to renew the mastic. Paint over cracked mastic will not stop the gaps, and the new mastic is traditionally left unpainted. Around Peper Harow, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not guesswork. That is why we ask a few questions first and agree the price before starting.

Frames and glazing around Peper Harow
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Wanborough Manor (about 3 miles north) are a reminder that the area around Peper Harow has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Homes close to Church of St Nicholas include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in. For site and facilities teams at buildings such as St Mary's CofE Voluntary Controlled Infant School, its window and door frames need their mastic kept sound, just like a home’s.

Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
Do you need sand mastic in Peper Harow?
Paint, silicone or cement used over old mastic causes problems. They don’t suit the joint and we normally remove them.
If you can see any of these, it’s time to have the joints looked at:
- Silicone on a period window that looks wrong
- Tired mastic found when preparing windows for paint
- Draughts and rain around sash boxes
- Cracked mastic round a front door frame

Peper Harow: your questions answered
I let a flat near Godalming station. Can you help?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear price.
Do you cover Peper Harow for sand mastic?
Yes. We work across London and the South East, and Peper Harow is part of that. Just ring 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear quote.
Will there be a smell?
Possibly a little. It fades as the sealant cures, and ventilation helps.
What information do you need?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned.
Can I do it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Are you an approved applicator?
Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
What we do, step by step
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes a few hours per window, depending on the condition of the joints from start to finish. In a small place like Peper Harow, access is generally 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.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic isn’t too thick.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
Getting ready for the visit
- Mention if the joints have been sealed before
- Move anything stored near the joints
- Mention any leaks or damp you’ve noticed
