About our sand mastic in Binfield Heath
Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. Renewing it closes the gap and tidies the surround. Common call-outs are for gaps where the frame meets the masonry and a silicone bead on a sash window that spoils the look, across brick reveals, sash and case windows and tenement windows.
In a village or hamlet like Binfield Heath, 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.

Common problems we fix in Binfield Heath
Age is the main cause. Even well-laid mastic needs renewing in time and how long it lasts depends on the weather it faces.
It’s worth asking for a quote if you see:
- Mastic worn away on windows facing the weather
- Wind and rain getting in round a sash window
- Old cement repairs round a window that have failed
- Old sand mastic that has cracked, crumbled or fallen out
Managing a site like Shiplake Church of England School? Then larger buildings have plenty of frames, and the mastic around each one ages.

Which is right for my windows, sand mastic or modern sealant?
We’ll talk it through with you. Sand mastic suits many period homes, and modern sealants suit newer frames.
When will the new mastic be hard?
It forms a skin fairly soon and it hardens fully over a longer time. Timing depends on the weather and the joint.
Can you replace silicone on a period window with sand mastic?
Yes, we do this often. The old silicone has to come out completely so the mastic beds in well.
What should I tell you?
Let us know what needs doing and where. We will ask anything else we need to know.
Is it messy?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
What happens on the day
There isn’t much for you to do on the day. Point us to the joints and we’ll get on with it. The work itself takes a few hours per window, depending on the condition of the joints.

Advice
Why act early in Binfield Heath
Filling over old, loose mastic doesn’t last. We remove the loose material first so the new mastic stays put. In a small place like Binfield Heath, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we will explain what it covers.

Sand mastic in Binfield Heath: local notes
With historic houses such as Greys Court (about 3.3 miles north) nearby, there’s older building stock in the area around Binfield Heath as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s 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.
Letting a property close to Shiplake station? Then any sash windows need sound mastic to keep draughts and rain out. For an older house near a landmark such as All Saints Church, the joint between an old wall and a newer frame is generally the first place rain gets in.

How the job changes by surface
Sash and case windows
On a sash window, the mastic joint shows on the outside, so a neat, even finish matters.
Tenement and terrace windows
Windows above ground floor need the right access. Let us know the floor and we’ll confirm access.
Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
