What we do, step by step
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours per window, depending on the condition of the joints and we leave things clean and tidy. For a job in Bordon, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We check each window surround and the condition of the joint.
- 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.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Try not to wet indoor joints just before the visit
- Let us know about stairs, lifts or work at height

Advice
Sand mastic in Bordon, done properly
Old sand mastic cracks, crumbles and falls out over time, leaving gaps round the window. Renewing it closes the gap so the surround looks right again. Typical jobs include old cement repairs round a window that have failed and wind and rain getting in round a sash window, across sash and case windows, brick reveals and period & listed homes.
Homes around Bordon range from older properties to newer houses, and their windows range just as widely. The right sealant depends on the frame and on what it sits in.
We stand behind the work with a one-year guarantee, so you are covered after we’ve gone.

Bordon homes and the weather
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For landlords with property near Liphook station, older sash windows in a rental need their mastic kept sound to keep the weather out. If you live in an older home near St Mark's Sacred Church, the joint between an old wall and a newer frame is generally the first place rain gets in. If you look after a building such as Bordon Infant School, larger buildings have plenty of frames, and the mastic around each one ages.

Why it’s worth doing now in Bordon
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic is the traditional material and finishes neatly against the masonry. Around Bordon, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.

Keeping the joints in good condition
After the cure time, these simple habits help:
- Renew mastic before redecorating the windows
- Avoid patching sand mastic with silicone
- Check with your local planning authority if your home is listed
- Have rotten timber repaired before new mastic goes in
Leave the new mastic unpainted, which is the traditional advice. If you’re redecorating, ask us first.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.

Do you cover smaller places like Bordon?
Yes, Bordon is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
What’s sand mastic made of?
It’s the traditional filler for the joint round timber windows and doors. It’s made with sand and a linseed-oil-based binder.
Is it possible to paint over sand mastic?
It’s traditionally left unpainted, as guidance on traditional windows advises. Ask us before decorating.
How long does sand mastic take to harden?
It forms a skin fairly soon and it hardens fully over a longer time. Timing depends on the weather and the joint.
Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Does someone need to be in?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.
How much does sand mastic cost in Bordon?
It depends on the job, so we quote each one individually. For a quick quote, phone 0345 464 0079 or drop us an email with a short description of the job.
When it is not the sealant
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:

- Planning or listed building consent (your local planning authority decides)
- Sash cords, weights and draught-proofing of the sashes
If in doubt, ring 0345 464 0079 or email us and we will say what we think before booking.
