How we handle sand mastic in Bury
For a listed home or one in a conservation area, ask your local planning authority if consent is needed before window work. Like-for-like sand mastic is often the preferred finish. If you have silicone on a period window that looks wrong and mastic round period door frames that has failed, we can put it right.
Somewhere as small as Bury, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
All of our work is guaranteed for twelve months.

Why deal with it now?
Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic suits the building and finishes neatly against the masonry. In a small place like Bury, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What it costs depends on the amount of work, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.
What you get with us
- Neat joints and a tidy finish
- We never seal over old sealant

Frames and glazing around Bury
Historic houses like Bignor Roman Villa (about 1.7 miles north-west) are a reminder that the area around Bury has older buildings as well as new. Where a home is older, 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 let a flat or house near Amberley station, cracked sand mastic around sash windows lets in the draughts tenants complain about. If you look after a building such as Bury CofE Primary School, its window and door frames need their mastic kept sound, just like a home’s. Homes close to The Parish Church of St John the Evangelist include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Do you cover smaller places like Bury?

Can I add another job to the visit?

How long does sand mastic take to go off?
It takes a while. The skin forms first, and the full set comes later and we will give you an idea for your job.
What’s sand mastic made of?
A traditional pointing material made from sand and a linseed-oil-based binder for the joint between timber frames and masonry.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all.

- How much there is to do
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we will go through it with you.

Stone surrounds
We take care not to mark the stone while raking out the old mastic.
Timber door frames
Doors face weather and wear, so their mastic can fail sooner. It’s renewed by hand.

We regularly work with letting and managing agents. Tell us the address, the job and how access works.
If you manage several properties in or around Bury, several properties can go on one quote. Send us the addresses and the work at each.

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
