Windows and doors in Little Chesterford
With historic houses such as Audley End House (about 2.3 miles south) nearby, there’s older building stock in the area around Little Chesterford as well as newer homes. In older buildings, 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, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For an older house near a landmark such as Church of St Mary the Virgin, frames set in older brick or stone need a sealant that suits the wall as well as the frame. If you let a flat or house near Great Chesterford station, any sash windows need sound mastic to keep draughts and rain out.

Sand mastic for homes and businesses in Little Chesterford
Burnt sand mastic is a traditional material that sits naturally against stone and brick. It suits period and listed homes where a modern sealant bead would stand out. Typical jobs include mastic dropping out of the joint and wind and rain getting in round a sash window, on brick reveals, period & listed homes and timber door frames.
In a village or hamlet like Little Chesterford, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
There’s a 12-month guarantee on every job.

Landlords, agents and businesses in Little Chesterford
Letting agents often deal with us directly. Tell us the address, the job and how access works.
In hotels, rooms out of use cost money, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.
DIY versus a professional finish
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
What a professional job adds is preparation and the right 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.

How we quote for sand mastic
Every job gets its own quote. These are the things that affect it:
- When we can work, for business premises
- How easy the joints are to reach

- Whether it has been sealed before

- Where the job is, and your postcode
- How many joints, rooms or windows are involved

Related advice
Keeping the joints in good condition
So the new joints stay in good condition:
- Look over the window mastic once a year
- Ask the planning authority about consent for listed or conservation-area homes
- Ask a joiner to look at soft timber first
- Sort the mastic before the decorators arrive
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
