Sand mastic for sash & case windows in Hyde, Hampshire

Sand mastic for homes and businesses in Hyde
Across Hyde, we renew sand mastic around sash and case windows. Every joint is cleaned out and filled by hand, finished to suit the masonry. We work on sash and case windows, period & listed homes and brick reveals, and common reasons people get in touch are mastic round period door frames that has failed and a silicone bead on a sash window that spoils the look.
In a smaller place like Hyde, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. That is hard on the mastic around frames and sills.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

What happens on the day
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a single window, longer for several. Parking around Hyde is usually easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.
How to prepare
- Let us know about stairs, lifts or work at height
- Tell us if parking is tricky
- Clear the area around the work

Windows and doors in Hyde
London and the South East are among the drier parts 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 Winchester station, cracked sand mastic around sash windows lets in the draughts tenants complain about. Homes close to St Bartholomew'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 St Bede Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s.

Near you in Hyde
Typical jobs here are in homes near Peter Symonds College, Leigh House Hospital and The King Alfred pub and the streets around them. There’s a railway station in Hyde itself: Winchester station. Well-known places in the area include Winchester Castle (0.6 miles south-west) and Royal Observer Corps Museum (0.5 miles north). Open spaces near Hyde include Winnall Moors and Twyford Down.
What happens if it’s left?
Gaps round a sash window let in rain and draughts. Water can get to the frame and the masonry so renewing it early protects the window. Around Hyde, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
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 doesn’t work out, we can still put it right.
What we can’t put right
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Broken panes
- Planning or listed building consent (your local planning authority decides)
- Crumbling stone or brickwork round the window
If you’re not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer.

Aftercare tips
Aftercare is simple, and it makes a real difference:
- Have rotten timber repaired before new mastic goes in
- Check the mastic when you check the paintwork
- Don’t paint over the new mastic
- Renew mastic before redecorating the windows
Look at the mastic when you look over the windows. Catching cracks early keeps repairs small.
An open joint round the box lets weather through. Left, the gap tends to get bigger.

The box of a sash and case window sits in the stone or brick opening. Sand mastic seals the joint round it.
Brick reveals
