Sand mastic for sash & case windows in Shalden, Hampshire

Sand mastic for homes and businesses in Shalden
Sand mastic doesn’t last for ever and gaps open up round the frame. We rake it out and renew it so the surround looks right again. Common call-outs are for a silicone bead on a sash window that spoils the look and crumbling sand mastic round a window, across brick reveals, timber door frames and period & listed homes.
In a village or hamlet like Shalden, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
A one-year guarantee comes as standard.

Why it’s worth doing now in Shalden
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. Where a wall is exposed, as many are in small places like Shalden, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
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. You will have a clear quote before any work starts, so you know where you stand.

How it works
On the day, we look over the joints with you first. Surfaces next to the work are protected before any work starts. Most jobs take anything from a few hours to a full day, depending on how many windows. Somewhere like Shalden needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- 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 finish is dressed so it sits neatly against the stone or brick.
Getting ready for the visit
- Mention any parking rules near the property
- Mention any sign-in or site rules at work premises
- Clear the area around the work

For sand mastic in Shalden, ring 0345 464 0079 or send us an email. A short description of the job and where it is helps us quote, and we’ll agree the price before any work begins.
Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.

Your questions about sand mastic in Shalden
Can you help a landlord with a rental near Alton station?
Yes, we work for landlords and agents. You can call 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before any work starts.

Do you offer different sealant colours?
Generally, yes. Sealants come in white, clear, grey and other colours for many products, and we agree the colour with you before work begins.
Should I check with the council before work on a listed or conservation-area home?
Checking first is sensible. Ask your local planning authority whether consent is needed for listed or conservation-area properties.
Is sand mastic better than silicone for my windows?
We’ll help you decide. Period homes often look best with sand mastic, and modern sealants suit newer frames.
Is it possible to take out silicone and use sand mastic instead?
Often, yes. Once the silicone is out and the joint prepared, sand mastic is applied by hand.
Are you insured?
Yes, we’re fully insured for every job we do.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.

Sand mastic in Shalden: local notes
Historic houses like Hall Place (about 2.5 miles south-west) are a reminder that the area around Shalden has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around Church of St Peter and St Paul, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you let a flat or house near Alton station, older sash windows in a rental need their mastic kept sound to keep the weather out.

Timber door frames
Round a period front door, sand mastic gives the right look.
Stone surrounds
Stone openings are rarely perfectly straight, so the gap isn’t the same all the way round. Sand mastic is shaped by hand to suit.
