Sand mastic in South Holmwood
Silicone on a period window often looks wrong and is not always the right material. Sand mastic is the traditional choice, and we can replace one with the other. Common call-outs are for mastic dropping out of the joint and window mastic to renew ahead of painting, across sash and case windows, brick reveals and period & listed homes.
Somewhere as small as South Holmwood, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Windows and doors in South Holmwood
Historic houses like Polesden Lacey (about 5 miles north-west) are a reminder that the area around South Holmwood has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For landlords with property near Holmwood station, cracked sand mastic around sash windows lets in the draughts tenants complain about. For an older house near a landmark such as Church of St Mary Magdalene, the joint between an old wall and a newer frame is normally the first place rain gets in.

FAQs for South Holmwood
Do you cover South Holmwood for sand mastic?
Yes. We work across London and the South East, and South Holmwood is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job.
Do you work for landlords with property near Holmwood station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Should I use sand mastic or silicone?
That depends on your windows. Period windows in stone or brick normally suit sand mastic, while modern frames normally get a flexible sealant.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
How long will you be here?
That depends on how much there is to do, but as a guide it takes a few hours for a single window, longer for several. We’ll give you a better idea when we quote.
Are you insured?
Yes, we are fully insured for every job we do.

What else we do in South Holmwood
Common problems we fix in South Holmwood
Most of it is simply age. Sand mastic is a maintenance item like any pointing and how long it lasts depends on the weather it faces.
If you can see any of these, it’s time to have the joints looked at:
- Cracked mastic round a front door frame
- Mastic that needs renewing before redecorating
- Crumbling sand mastic round a window
- Cement or filler used on old window joints that has cracked
If you look after a building such as The Priory CofE Voluntary Aided School, larger buildings have plenty of frames, and the mastic around each one ages.

Can I do it myself?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Why deal with it now?
Gaps round a sash window let in rain and draughts. Left, water can reach the timber and the wall so renewing it early protects the window. Around South Holmwood, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and agree the price before starting.

How it works
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours for a single window, longer for several and we leave things clean and tidy. In a small place like South Holmwood, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we look at the surrounds with you and agree what needs doing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic isn’t too thick.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The mastic is finished to sit tidily against the stone or brick.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- For business premises, tell us about site rules or sign-in
- For indoor joints, keep the area dry beforehand if you can
