How we handle sand mastic in Bishopsbourne
We work across Bishopsbourne renewing sand mastic on sash windows and doors. Every joint is cleaned out and filled by hand for a neat, traditional finish. Common call-outs are for a silicone bead on a sash window that spoils the look and wind and rain getting in round a sash window, on stone surrounds, timber door frames and period & listed homes.
Mastic can only go onto a dry, clean joint, so window work in Bishopsbourne is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

What affects the cost of sand mastic
Jobs vary more than people expect. What affects the quote:
- How much there is to do
- Working hours on commercial sites
- Whether old sealant or filler has to be cut out
- Access and height
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first.
Asking for a quote
You do not need to know the technical terms. It helps if you can tell us:
- How many joints, rooms or windows are involved
- The address or postcode of the job
- If it’s domestic, commercial or a hotel
- If someone has resealed it before
There’s no standard price list. Instead, your job gets its own clear quote. To arrange one, phone 0345 464 0079 or email us.

Frames and glazing around Bishopsbourne
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Goodnestone Park (about 4.1 miles east) are a reminder that the area around Bishopsbourne 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.
Homes close to Church of St Mary include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
Looking after it afterwards
So the new joints stay in good condition:
- Find out about consent before window work on a listed home
- Make sure water runs off the sill
- Inspect the joints round the windows every year or so
- Renew mastic before redecorating the windows
Avoid sealing over the mastic with silicone. If anything cracks, get it looked at rather than patching it.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall, so renewing it early is worth it.
Do you need sand mastic in Bishopsbourne?
Paint, silicone or cement used over old mastic causes problems. They don’t suit the joint, and they usually need raking out.
Signs it’s time to call us include:
- Silicone on a period window that looks wrong
- Crumbling sand mastic round a window
- Open joints round the window box
- Cracked mastic round a front door frame
For landlords with property near Bekesbourne station, any sash windows need sound mastic to keep draughts and rain out.
