Sand mastic for homes and businesses in Oving
Silicone on a period window often looks wrong and doesn’t suit the building. Sand mastic gives a finish that matches the age of the house and we can swap the silicone for it. Typical jobs include cement or filler used on old window joints that has cracked and failed mastic on an exposed elevation, on stone surrounds, tenement windows and period & listed homes.
Around Oving, 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.
Big or small, you get the same 12-month guarantee.

What else we do in Oving
DIY sealant or a professional job?
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.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Work for landlords, hotels and businesses
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.
What the job involves on each surface
Period and listed homes
Many older homes were built with sand mastic round the windows. If your home is listed, ask your local planning authority about consent.
Brick reveals
We rake out the old mastic and pack deep voids before the new mastic goes in.
What sealant work can’t fix
Some problems need a builder, plumber or other trade rather than us:
- Masonry that needs repairing
- Whether work needs listed building consent
- Cracked or broken glass
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly.
What we seal
- Tenement windows
- Stone surrounds
- Timber door frames

Frames and glazing around Oving
Historic houses like Waddesdon Manor (about 4.5 miles south-west) are a reminder that the area around Oving has older buildings as well as new. Where a home is older, 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.
For landlords with property near Aylesbury Vale Parkway station, any sash windows need sound mastic to keep draughts and rain out. If you look after a building such as Whitchurch Combined School, its window and door frames need their mastic kept sound, just like a home’s.

When to call us in Oving
Paint, silicone or cement used over old mastic causes problems. They don’t suit the joint and we normally remove them.
Any of these means the joints need attention:
- Mastic dropping out of the joint
- Window mastic to renew ahead of painting
- Draughty sash windows at the surround
- Gaps between timber frames and stone or brick
If you live in an older home near Church of All Saints, the joint between an old wall and a newer frame is usually the first place rain gets in.
