How we handle sand mastic in Lacey Green
Sand mastic does not last for ever, leaving gaps round the window. Renewing it closes the gap so the surround looks right again. If you have mastic that needs renewing before redecorating and draughts and rain around sash boxes, we can put it right.
In a village or hamlet like Lacey Green, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
You’re covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or send us an email.

Windows and doors in Lacey Green
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like West Wycombe Park House (about 3.8 miles south) are a reminder that the area around Lacey Green 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.
If you look after a building such as St John's Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near Saunderton station, older sash windows in a rental need their mastic kept sound to keep the weather out.

Other services in Lacey Green
Work for landlords, hotels and businesses
We work for letting agents and landlords as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Make sure water runs off the sill
- Find out about consent before window work on a listed home
- Keep modern sealant off the mastic
- Don’t paint over the new mastic
Leave the new mastic unpainted, as traditional guidance advises. If you’re redecorating, ask us first.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.
When something else is needed
We’ll always be straight with you, so here’s what new sealant won’t do:
- Sashes that need overhauling
- Crumbling stone or brickwork round the window
- Timber that has rotted
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly.

The process
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours per window, depending on the condition of the joints. Somewhere as small as Lacey Green, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- Mention any leaks or damp you’ve noticed
- Tell us about access, such as stairs, a lift or high-level joints

What the job involves on each surface
Sash and case windows
The box of a sash and case window sits in the stone or brick opening. Sand mastic seals the joint round it.
Brick reveals
An open joint at a brick reveal lets weather in. Renewing the mastic closes it.
Why act early in Lacey Green
Cement-based fillers and modern sealants do not always suit a period surround. Sand mastic matches what was there and that can be important for listed homes. Where a wall is exposed, as many are in small places like Lacey Green, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
