Sand mastic for homes and businesses in Old Malden
Silicone on a period window often looks wrong and does not suit the building. Sand mastic is the traditional choice and we can swap the silicone for it. If you have weathered mastic on the most exposed windows and tired mastic found when preparing windows for paint, we can put it right, on timber door frames, period & listed homes and stone surrounds alike.
In smaller places like Old Malden, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. Each frame material needs the right sealant against the right wall.
Every job is covered by a one-year guarantee, wherever you are in Surrey.

What happens if it’s left?
Draughts round a sash window aren’t always the sashes. Gaps between the frame and the wall can be just as bad and new mastic seals them. In a smaller place like Old Malden, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs. Ask us for a quote and we’ll explain what it covers.

What sand mastic looks like in Old Malden
Historic houses like Fitznells Manor (about 1.8 miles south-east) are a reminder that the area around Old Malden 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 is traditional sand mastic. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For site and facilities teams at buildings such as Knollmead Primary School, its window and door frames need their mastic kept sound, just like a home’s. Letting a property close to Tolworth station? Then any sash windows need sound mastic to keep draughts and rain out.

Questions from Old Malden
Is Old Malden in your area for sand mastic?
Yes. Our work covers London and the South East, and Old Malden is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear price.
Do you cover smaller places like Old Malden?
Yes, Old Malden is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is it OK to seal over old sealant?
No. The old sealant always comes out first.
Do you work for landlords and businesses?
Yes. Domestic, commercial and hotel work are all part of what we do.
Can I paint the new mastic?
It’s traditionally left unpainted, as guidance on traditional windows advises. Ask us before decorating.
Can tenants book the work?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Can you do several jobs on one visit?
Of course. Doing several areas at once is normally more efficient.
Do you remove the old sealant?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
For landlords and businesses
Letting agents and landlords in Old Malden can book us as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.
Letting agents often deal with us directly. Tell us the address, the job and how access works and we will give you a quote.
How the visit works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes anything from a few hours to a full day, depending on how many windows. In a smaller place like Old Malden, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- First, we look at the surrounds with you and agree what needs doing.
- Old, loose mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The mastic is finished to sit tidily against the stone or brick.
Getting ready for the visit
- Mention any parking rules near the property
- Mention if the joints have been sealed before
- Let us know about stairs, lifts or work at height
How to get a quote

When to call us in Old Malden
Decorating can disturb tired mastic. Many people find it crumbling when they prepare the windows, which is a good time to renew it.
People generally contact us after spotting one of these:
- Window mastic to renew ahead of painting
- Draughty sash windows at the surround
- Modern sealant on a period surround
- Patchy fillers round a sash window
In the older streets around Parish Church of St Mary the Virgin, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
