About our sand mastic in Passfield
We work across Passfield renewing sand mastic on sash windows and doors. Each joint is raked out, prepared and pointed by hand, finished to suit the masonry. We are often asked to deal with modern sealant on a period surround and draughty sash windows at the surround, across sash and case windows, tenement windows and timber door frames.
Around Passfield, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
Our work is backed for twelve months, in Passfield and everywhere else we cover.

How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Check with your local planning authority if your home is listed
- Keep sills and gutters clear so water drains away
- Ask a joiner to look at soft timber first
- Take care around the mastic when scraping paint
Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look rather than patching it.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall so early renewal protects both.
When it isn’t the sealant
Some problems need a builder, plumber or other trade rather than us:
- Sash cords, weights and draught-proofing of the sashes
- Crumbling stone or brickwork round the window
- Decisions on consent for listed homes
If you are not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer before booking.

DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Common questions in Passfield
I let a flat near Liphook station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear quote.
Do you cover smaller places like Passfield?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
What guarantee comes with the work?
Our 12-month guarantee applies to all our work.
Can new sealant go over the old?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Do you take out the old sealant first?
Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.
How long does sand mastic take?
A typical job takes a few hours for a single window, longer for several. Your quote will say how long we expect yours to take.
Should I check with the council before work on a listed or conservation-area home?
Speak to your local planning authority before work starts. Sand mastic is often favoured as like for like, but they decide.
Why it’s worth doing now in Passfield
If you are redecorating, renew the mastic first. Paint over cracked mastic will not stop the gaps, and the new mastic is traditionally left unpainted. Around Passfield, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.
Why us?
- 20+ years of sealant experience

What else we do in Passfield
How it works
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes anything from a few hours to a full day, depending on how many windows, including the tidy-up. Somewhere as small as Passfield, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Preparing for the visit
- Tell us if parking is tricky
- Mention any leaks or damp you’ve noticed
- For business premises, tell us about site rules or sign-in
Ask for a quote
Getting a quote is simple: tell us what needs doing and where. A few pictures by email make the job easier to understand, and we’ll take it from there.

Sand mastic in Passfield: local notes
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Schools such as Mill Chase Academy are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near Liphook station, cracked sand mastic around sash windows lets in the draughts tenants complain about.
