Sand mastic for sash & case windows in Privett, Hampshire
We cover Privett for traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old sealant removed completely, joints prepared properly.
- Weathered mastic on the most exposed windows
- Open joints round the window box
- Cracked mastic round a front door frame
What we do, step by step
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and tidy away. It usually takes a few hours for a single window, longer for several. In a smaller place like Privett, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- 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.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- On commercial sites, let us know about site rules
- Clear items away from the joints we are working on

Sand mastic for homes and businesses in Privett
Fresh sand mastic forms a skin quite soon, but it takes longer to harden fully. Traditional guidance is not to paint over it, so ask us before you decorate. We are often asked to deal with mastic round period door frames that has failed and draughts and rain around sash boxes, across timber door frames, brick reveals and stone surrounds.
In a smaller place like Privett, some walls face open ground and catch the full force of the weather. That’s hard on the mastic around frames and sills.
You are covered for a year from the day we finish. If anything isn’t right with it, phone 0345 464 0079 or drop us an email.

Windows and doors in Privett
Privett is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Schools such as Gomer Infant School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. For an older house near a landmark such as St Faith's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For landlords with property near Portsmouth Harbour station, older sash windows in a rental need their mastic kept sound to keep the weather out.

Questions from Privett
Can you help a landlord with a rental near Portsmouth Harbour station?
Yes. We work for landlords and agents as well as householders. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear price.
Is Privett within the area you cover?
Yes, Privett is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us.
Where do you work from?
We work from Crawley. Our applicators cover Privett, along with the rest of our area.
Do you have insurance?
Yes, we’re fully insured for every job we do.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Can sand mastic be painted?
It’s traditionally left unpainted, which is what traditional guidance recommends. Talk to us before any painting near it.
Can new sealant go over the old?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
What sealant work can’t fix
Some problems need a builder, plumber or other trade rather than us:
- Timber that has rotted
- Sash cords, weights and draught-proofing of the sashes
- Masonry that needs repairing
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly before you book.
What we seal
- Sash and case windows
- Period & listed homes
- Timber door frames
- Tenement windows
- Stone surrounds
- Brick reveals
Different surfaces, different methods
Tenement and terrace windows
In shared buildings, the windows may be part of a wider repair so it’s worth checking responsibilities.
Sash and case windows
A sash window’s box frame sits in the masonry opening. The gap round it is pointed with sand mastic.
Why act early in Privett
Not every filler suits an old window surround. Sand mastic matches what was there, which can matter on listed and conservation-area homes. In a smaller place like Privett, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first.

- Old sealant always removed completely
- Trusted Arbo and Everbuild sealants

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Look over the window mastic once a year
- Avoid patching sand mastic with silicone
- Ask a joiner to look at soft timber first
- Don’t paint over the new mastic
Make sure water drains away from the window surround. Constant wetting wears the mastic faster.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens as more mastic falls out.
