Sand mastic in Loxhill, done properly
Burnt sand mastic is a traditional material that sits naturally against stone and brick. It’s a good fit for period properties, where modern sealant can look out of place. If you’re dealing with draughty sash windows at the surround and old cement repairs round a window that have failed, we can put it right, on brick reveals, timber door frames and stone surrounds alike.
Mastic can only go onto a dry, clean joint, so window work in Loxhill is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
Every job is covered by our 12-month guarantee, wherever you are in Surrey.

Windows and doors in Loxhill
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Letting a property close to Witley station? Then older sash windows in a rental need their mastic kept sound to keep the weather out. For an older house near a landmark such as Church of St Peter, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

How it works
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes anything from a few hours to a full day, depending on how many windows. For a village or hamlet like Loxhill, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We check the window surrounds and agree which joints need renewing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Keep children and pets away from the work area
- On commercial sites, let us know about site rules

When something else is needed
In fairness, there are a few things sealant won’t fix:
- Timber that has rotted
- Sash cords, weights and draught-proofing of the sashes
- Planning or listed building consent (your local planning authority decides)
If you’re not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer.
Surfaces we seal
- Timber door frames
- Tenement windows
- Stone surrounds
- Brick reveals
- Period & listed homes
- Sash and case windows
Looking after it afterwards
So the new joints stay in good condition:
- Keep modern sealant off the mastic
- Have rotten timber repaired before new mastic goes in
- Inspect the joints round the windows every year or so
- Check with your local planning authority if your home is listed
Leave the new mastic alone while it firms up. It forms a skin fairly soon but needs longer to fully harden.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber and timber that stays wet can rot.
Loxhill questions
I let a flat near Witley station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Is Loxhill in your area for sand mastic?
Yes, Loxhill is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job, and we will send you a clear quote.
Are you fully insured?
Yes, we are fully insured for every job we do.
What is sand mastic?
Sand plus a binder based on linseed oil. It’s built up in the joint by hand and shaped to suit the surround.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
How long does the job take?
A typical job takes a few hours per window, depending on the condition of the joints, including preparation and clearing up. Your quote will say how long we expect yours to take.
Can you replace silicone on a period window with sand mastic?
Normally, yes. Once the silicone is out and the joint prepared, sand mastic is applied by hand.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
Can I do it myself?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
