Sand Mastic in Tatsfield

Sand mastic for homes and businesses in Tatsfield
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s a mix of sand and a linseed-oil-based binder and built up by hand. On older homes, it suits the building far better than silicone. If you have open joints round the window box and cracked mastic round a front door frame, we can help, whatever the surface.
London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. The mastic around them dries out and cracks with age, letting in draughts and water.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

Aftercare tips
So the new joints stay in good condition:
- Get any rot dealt with first
- Go gently near the mastic when preparing windows
- Keep sills and gutters clear so water drains away
- Don’t paint over the new mastic
Do not run silicone over the new mastic. If anything cracks, get it looked at before trying a quick fix.
An open joint round the box lets weather through. Left, the gap tends to get bigger.
What we can’t put right
Sealant is not the answer to every problem, and we will tell you before work begins. It will not solve:
- Sashes that need overhauling
- Crumbling stone or brickwork round the window
- Planning or listed building consent (your local planning authority decides)
If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before you book.

Questions from Tatsfield
Can you help a landlord with a rental near Oxted station?
Yes. We work for landlords and agents as well as homeowners, 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 parking be tricky for a visit in Tatsfield?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
Can sand mastic be painted?
The usual advice is to leave sand mastic unpainted. Ask us before you decorate around it and we’ll advise.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
Should I use sand mastic or silicone?
We’ll talk it through with you. Period homes often look best with sand mastic and newer frames suit modern sealant.
Can new sealant go over the old?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Frames and glazing around Tatsfield
In a converted house or block, who looks after the windows depends on the lease, so it’s worth checking before booking. With historic houses such as Titsey Place (about 1.4 miles south-west) nearby, there’s older building stock in the area around Tatsfield as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Tatsfield is in London, so parking needs planning: let us know about parking bays, permits or a driveway. Rented homes near Oxted station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. In the older streets around Church of St Mary the Virgin, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Many older homes were built with sand mastic round the windows. On listed buildings, check with your planning authority first.
