Sand mastic for homes and businesses in Frogham
Sand mastic does not last for ever and gaps open up round the frame. We rake it out and renew it and tidies the surround. We work on tenement windows, period & listed homes and brick reveals, and people most often call us about draughty sash windows at the surround and failed mastic on an exposed elevation.
In a village or hamlet like Frogham, 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.
You get a one-year guarantee, the same in Frogham as everywhere else we work.

Leave it or put it right?
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic is the traditional material and blends with the stone or brick. In a small place like Frogham, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
A failed joint rarely gets cheaper to fix by waiting. If you are unsure, call 0345 464 0079 or email us for an honest opinion and a quote.

Windows and doors in Frogham
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Breamore House (about 4 miles north) are a reminder that the area around Frogham has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Homes close to Church of the Holy Ascension include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
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.
What we cannot put right
A few problems are outside what sealant work can do:
- Sashes that rattle, stick or won’t open
- Cracked or broken glass
- Planning or listed building consent (your local planning authority decides)
If in doubt, ring 0345 464 0079 or email us and we will say what we think.
Surfaces we seal
- Timber door frames

What affects the cost of sand mastic
Every job gets its own quote. This is what makes a difference:
- Any working-time requirements on site
- Access and height
- The old material and how stubborn it is
- Any mould that needs treating
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.
What we need to know
There’s no need for technical detail. Just tell us:
- Where the property is
- The rough size of the job
- A few photos by email, if you can
- Whether it’s a home or a business
There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To get started, call 0345 464 0079 or email us.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Keep modern sealant off the mastic
- Avoid heavy scraping on the mastic joint
- Get any rot dealt with first
- Check the mastic when you check the paintwork
Leave the new mastic unpainted, as traditional guidance advises. If you are redecorating, ask us first.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.

Signs you need sand mastic in Frogham
Sand mastic slowly weathers. It dries out, cracks and loses its grip on the stone or timber.
Common reasons people contact us are:
- Silicone on a period window that looks wrong
- Gaps round a timber door in stone or brick
- Tired mastic found when preparing windows for paint
- Gaps where the frame meets the masonry
Schools such as Hyde Church of England Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.
