Windows and doors in Leckford
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you look after a building such as Test Valley School, its window and door frames need their mastic kept sound, just like a home’s.

How we handle sand mastic in Leckford
Burnt sand mastic is a traditional material that sits naturally against stone and brick. It suits period and listed homes, where modern sealant can look out of place. Common call-outs are for old sand mastic that has cracked, crumbled or fallen out and weathered mastic on the most exposed windows, on sash and case windows, timber door frames and stone surrounds.
Somewhere as small as Leckford, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
The work is covered for a year after we finish. If anything is not right with it, phone 0345 464 0079 or send us an email.

Common problems we fix in Leckford
Some old mastic was never deep enough. Mastic that is too thin cracks and drops out so we make sure the new mastic is the right thickness.
Most people get in touch after spotting something like this:
- A silicone bead on a sash window that spoils the look
- Gaps where the frame meets the masonry
- Mastic round period door frames that has failed
- Tired mastic found when preparing windows for paint
Homes close to Church of St Nicholas include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Questions to ask before booking
- Is the old sealant removed completely?
- What preparation is included
- How the colour is chosen
- Whether VAT is included

Common questions in Leckford
Will you come out to Leckford?
Yes, Leckford is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is sand mastic in Leckford guaranteed?
All our work, in Leckford and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Should I check with the council before work on a listed or conservation-area home?
It’s best to ask your local planning authority first. Sand mastic is often favoured as like for like but the decision is theirs.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
How do I get a quote for sand mastic in Leckford?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before we start.
Is sand mastic better than silicone for my windows?
For period timber windows in stone or brick, sand mastic is often the better fit. On modern frames, we’d normally use a flexible sealant.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
How long does sand mastic take to harden?
The surface skins quite quickly, then hardens over a longer period. The weather and joint depth both affect it.
Why it’s worth doing now in Leckford
Draughts round a sash window aren’t always the sashes. Gaps between the frame and the wall can be just as bad, and renewing the mastic closes them. Around Leckford, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

The process
On the day, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before any work begins. Most jobs take a few hours for a single window, longer for several. For a village or hamlet like Leckford, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.

How the job changes by surface
Tenement and terrace windows
Upper-floor windows need access planning. Tell us the height and we’ll confirm what’s needed.
Stone surrounds
Stone surrounds suit sand mastic well. The finish blends with the masonry.
What we cannot put right
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Masonry that needs repairing
- Rotten sashes, sills or window boxes (a joiner’s job)
- Sashes that rattle, stick or won’t open
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think before you book.
What we seal
- Period & listed homes
- Timber door frames
