Sand mastic for homes and businesses in Woodford Wells
Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. Renewing it closes the gap so the surround looks right again. We work on period & listed homes, stone surrounds and tenement windows, and the jobs we see most are gaps round a timber door in stone or brick and mastic dropping out of the joint.
Much of London’s older housing was built with timber sash windows, some still in place and some long since replaced. Whatever is in the opening now, the joint between frame and wall is what keeps the weather out.
All our work is covered by our one-year guarantee, wherever you are in Greater London.

The process
You don’t need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the job takes a few hours per window, depending on the condition of the joints for a typical job. In Woodford Wells, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
How to prepare
- Tell us if parking is tricky
- Where the joints are inside, avoid wetting them before we arrive
- For business premises, tell us about site rules or sign-in

Advice
What affects the quote in Woodford Wells
Some jobs are bigger than they look, and some smaller. The main factors:
- How many areas need sealing
- Which sealant suits the joint
- How easy the joints are to reach
- Any working-time requirements on site
The cost depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts.
What to tell us for a quote
When you contact us, it’s useful to know:
- What’s wrong with the joints now
- How many joints, rooms or windows are involved
- If someone has resealed it before
- The address or postcode of the job
Every job is quoted individually, so start by telling us what you need. Simply ring 0345 464 0079 or email us and describe the job and send pictures if you have them.
Leave it or put it right?
New sash windows are a major, costly change and on a listed home, consent may be needed. Where the frames are in good order, new mastic seals the surround. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Woodford Wells, the repair is bigger than a sealant job.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
What you get with us

Frames and glazing around Woodford Wells
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Valentines Mansion (about 3.3 miles south-east) are a reminder that the area around Woodford Wells 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.
In the older streets around All Saints' Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. For site and facilities teams at buildings such as Wells Primary School, its window and door frames need their mastic kept sound, just like a home’s. For landlords with property near Highams Park station, any sash windows need sound mastic to keep draughts and rain out.

What the job involves on each surface
Period and listed homes
Sand mastic is the like-for-like choice for many period homes. If your home is listed, ask your local planning authority about consent.
Sash and case windows
The mastic round a sash window is on show, so a neat, even finish matters.
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Clear gutters so water doesn’t pour onto the windows
- Keep modern sealant off the mastic
- Take care around the mastic when scraping paint
- Have rotten timber repaired before new mastic goes in
Check the mastic when you check the paintwork. Catching cracks early keeps repairs small.
An open joint round the box lets weather through. Left, the gap tends to get bigger.
Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
