Sand mastic in Chalkhouse Green, done properly
Our applicators renew the sand mastic around sash and case windows and doors in stone and brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. If you’re dealing with gaps between timber frames and stone or brick and mastic that needs renewing before redecorating, we can put it right, whatever the surface.
Mastic can only go onto a dry, clean joint, so window work in Chalkhouse Green is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
A one-year guarantee comes as standard, so you are covered after we have gone.

Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.

Surface by surface
Tenement and terrace windows
Upper-floor windows need access planning. Tell us the height and we’ll confirm what’s needed.
Sash and case windows
A sash window’s box frame sits in the masonry opening. Sand mastic seals the joint round it.
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 new mastic seals them. Older cottages and farmhouses around Chalkhouse Green can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or send us an email and we’ll talk you through it.

Sand mastic in Chalkhouse Green: local notes
With historic houses such as Mapledurham House (about 2.6 miles west) nearby, there’s older building stock in the area around Chalkhouse Green as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. 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.
Homes close to Saint Barnabas Emmer Green include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you look after a building such as Emmer Green Primary School, larger buildings have plenty of frames, and the mastic around each one ages. For landlords with property near Reading station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we are done.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
What’s sand mastic made of?
Sand mastic is a traditional material for pointing round windows and doors. It combines sand with a linseed-oil-based binder.
I’m a tenant. Can you help?
We can work for tenants, landlords or agents. Just make sure your landlord agrees.
How long does sand mastic take?
That depends on how much there is to do, but most jobs take anything from a few hours to a full day, depending on how many windows. We’ll give you a better idea when we quote.
Looking after it afterwards
To keep the joints looking good and working properly:
- Check with your local planning authority if your home is listed
- Sort the mastic before the decorators arrive
- Take care around the mastic when scraping paint
- Look over the window mastic once a year
Leave the new mastic alone while it firms up. It forms a skin fairly soon, but takes longer to harden fully.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
