- Open joints round the window box
- Cracked mastic round a front door frame
- Old sand mastic that has cracked, crumbled or fallen out
- Mastic that needs renewing before redecorating

How we handle sand mastic in Almshouse Green
A silicone bead around a sash window can look out of place and doesn’t suit the building. Sand mastic is the traditional choice and we can swap the silicone for it. If you’re dealing with open joints round the window box and failed mastic on an exposed elevation, we can help, on stone surrounds, tenement windows and brick reveals alike.
Somewhere as small as Almshouse Green, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

What we do, step by step
On the day, there’s very little for you to do. Show us the job and we will take it from there. The job generally takes a few hours per window, depending on the condition of the joints from start to finish. Somewhere as small as Almshouse Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Where the joints are inside, avoid wetting them before we arrive
- Keep children and pets away from the work area

How much does sand mastic cost in Almshouse Green?
Size, access and the old material all affect the cost. Ask us for a quote and we’ll talk you through it.
What the job involves on each surface
Timber door frames
Door frames get knocked and soaked and the mastic can crack early. We rake it out and renew it.
Tenement and terrace windows
Windows above ground floor need the right access. Tell us the height and we will confirm what’s needed.
Honest limits
A few problems are outside what sealant work can do:
- Decayed frames that need repair
- Masonry that needs repairing
- Decisions on consent for listed homes
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly.
Surfaces we seal
- Stone surrounds
- Timber door frames
- Tenement windows
- Brick reveals
- Sash and case windows
- Period & listed homes
Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Inspect the joints round the windows every year or so
- Renew mastic before redecorating the windows
- Make sure water runs off the sill
- Check with your local planning authority if your home is listed
Keep gutters and sills clear so water runs away from the surround. Water sitting against the mastic shortens its life.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.
Sand mastic in Almshouse Green: local notes
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Hedingham Castle (about 2.4 miles north-east) are a reminder that the area around Almshouse Green has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Managing a site like Hedingham School and Sixth Form? Then the mastic around its windows and doors needs looking after like any other building’s.
