Sand mastic for homes and businesses in Oare
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s made from sand and a linseed-oil-based binder and built up by hand. On period homes, it looks right where silicone wouldn’t. We work on period & listed homes, sash and case windows and brick reveals, and people most often call us about cracked mastic round a front door frame and crumbling sand mastic round a window.
Outdoor sealant needs dry, clean surfaces, so work on frames around Oare is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Is there any odour?

Surface by surface
Timber door frames
Round a period front door, sand mastic gives the right look.
Sash and case windows
The box of a sash and case window sits in the stone or brick opening. Sand mastic seals the joint round it.
Oare homes and the weather
With historic houses such as Shaw House (about 4 miles south-west) nearby, there’s older building stock in the area around Oare as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you look after a building such as Hermitage Primary School, its window and door frames need their mastic kept sound, just like a home’s. Letting a property close to Newbury Racecourse station? Then any sash windows need sound mastic to keep draughts and rain out.

Landmarks near Oare
Around Oare, our work takes us to homes and buildings near The White Horse pub. For rail, the closest station is Newbury Racecourse station, about 4.7 miles south of the centre. Other landmarks nearby include Hampstead Norris Castle (1.8 miles north-east) and West Berkshire Community Hospital (4 miles south). Not far away are Snelsmore Common.
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Other services in Oare
Leave it or put it right?
Draughts round a sash window aren’t always the sashes. Gaps between the frame and the wall can be just as bad, and renewing the mastic closes them. Older cottages and farmhouses around Oare can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

How the visit works
When we arrive, we look over the joints with you first, so you know exactly what we’re doing. Surfaces next to the work are protected before work begins. The work usually takes a few hours per window, depending on the condition of the joints. For a village or hamlet like Oare, the journey is planned in advance: 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 check the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- Large voids are packed out first, so the mastic is not too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
Getting ready for the visit
- Clear the area around the work
- Keep children and pets away from the work area

When to call us in Oare
Paint, silicone or cement used over old mastic causes problems. They don’t suit the joint, and they generally need raking out.
Any of these means the joints need attention:
- A silicone bead on a sash window that spoils the look
- Mastic round period door frames that has failed
- Cement or filler used on old window joints that has cracked
- Gaps where the frame meets the masonry
For an older house near a landmark such as Church of St Bartholomew, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
