Sand mastic in Beech Hill
Fresh sand mastic forms a skin quite soon, but it takes longer to harden fully. Traditionally, sand mastic is left unpainted and we will advise if you are redecorating. Common call-outs are for old cement repairs round a window that have failed and failed mastic on an exposed elevation, across timber door frames, stone surrounds and brick reveals.
Homes in small places like Beech Hill often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
Whatever the size of the job, you get the same one-year guarantee.

Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Avoid patching sand mastic with silicone
- Go gently near the mastic when preparing windows
- Plan mastic work ahead of painting
- Ask us before painting near the mastic
Leave the new mastic unpainted, which is the traditional advice. If you are redecorating, ask us first.
Sound mastic protects the frame. Failed mastic lets water reach the timber and timber that stays wet can rot.

What’s sand mastic made of?
Sand mastic is a traditional material for pointing round windows and doors. It’s made with sand and a linseed-oil-based binder.
Are you fully insured?
Yes, we are fully insured.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Is sand mastic better than silicone for my windows?
We’ll help you decide. Sand mastic suits many period homes, and modern sealants suit newer frames.
When to call us in Beech Hill
Some old mastic was never deep enough. A thin layer does not hold well, which is why we pack deep voids first and get the depth right.
If you can see any of these, it’s time to have the joints looked at:
- Mastic round period door frames that has failed
- Weathered mastic on the most exposed windows
- Window mastic to renew ahead of painting
- Open joints round the window box
Managing a site like Lambs Lane Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.

Sand mastic in Beech Hill: local notes
Historic houses like Stratfield Saye House (about 1.7 miles south) are a reminder that the area around Beech Hill has older buildings as well as new. 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, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Letting a property close to Mortimer station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about. In the older streets around Church of St Mary the Virgin, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Why act early in Beech Hill
Not every filler suits an old window surround. Sand mastic is the like-for-like choice, which can matter on listed and conservation-area homes. Older cottages and farmhouses around Beech Hill can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are unsure, phone 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.

What happens on the day
On the day, we start by going over the job with you, so you know exactly what we’re doing. We protect the surfaces around the joints before any work begins. The work usually takes anything from a few hours to a full day, depending on how many windows. Somewhere as small as Beech Hill, 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.
- The loose and crumbling mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- We dress the surface so it sits neatly against the masonry.

DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
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.
What affects the cost of sand mastic
You’ll get a clear quote before work begins. It takes into account:
- How much there is to do
- The type of sealant required
- Whether there’s mould to deal with
- How many rooms, windows or areas are involved
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part.
What to tell us for a quote
Photos help, but a description is a good start. Please mention:
- Access, such as stairs, a lift or height
- Pictures of the joints, sent by email
- Where the property is
- If someone has resealed it before
