Frames and glazing around West Green
With historic houses such as Stratfield Saye House (about 4.6 miles north-west) nearby, there’s older building stock in the area around West Green as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. 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.
Homes close to St Mary's Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For site and facilities teams at buildings such as Greenfields Junior School, the mastic around its windows and doors needs looking after like any other building’s.

Sand mastic in West 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 gaps round a timber door in stone or brick and gaps between timber frames and stone or brick, we can help, on tenement windows, sash and case windows and brick reveals alike.
Around West Green, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
All our work is covered by our 12-month guarantee, wherever you are in Hampshire.

Do you hold any approvals?

When it is not the sealant
New sealant cannot fix everything, and we will tell you before work begins. Sealant won’t put right:
- Decayed frames that need repair
- Sashes that need overhauling
- Masonry that needs repairing
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly.

- Stone surrounds
- Period & listed homes
- Brick reveals
- Sash and case windows
- Tenement windows
- Timber door frames
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Avoid patching sand mastic with silicone
- Avoid heavy scraping on the mastic joint
- Keep sills and gutters clear so water drains away
- Find out about consent before window work on a listed home
Don’t touch or press the mastic while it hardens. It forms a skin fairly soon, but takes longer to harden fully.
An open joint round the box lets weather through. Left, the gap tends to get bigger.
What we do, step by step
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a single window, longer for several, and the area is left clean. Somewhere as small as West Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- Large voids are packed out first, so the mastic is not too thick.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The mastic is finished to sit tidily against the stone or brick.
How to prepare
- For business premises, tell us about site rules or sign-in
- Let us know if you’ve seen damp or leaks
- Mention any parking rules near the property
How to get a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email pictures if that is easy.

Why deal with it now?
Not every filler suits an old window surround. Sand mastic is the like-for-like choice, which can matter on listed and conservation-area homes. Older cottages and farmhouses around West Green can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote.

For landlords and businesses
For anyone letting property in or around West Green, jobs at different addresses can go on one quote. Send us the addresses and the work at each.
We work for letting agents and landlords as well as householders. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.

Common problems we fix in West Green
Water gets into small cracks in the mastic and pushes it out. Exposed elevations normally fail first.
It’s worth asking for a quote if you see:
