Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
Sand mastic in Istead Rise, done properly
If your home is listed or in a conservation area, check with your local planning authority if consent is needed before window work. Sand mastic is often favoured as a like-for-like material. If you’re dealing with old cement repairs round a window that have failed and mastic round period door frames that has failed, we can put it right, on timber door frames, sash and case windows and brick reveals alike.
Homes in small places like Istead Rise 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.
There’s a 12-month guarantee on every job, large or small.

Frames and glazing around Istead Rise
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. With historic houses such as Cobham College (about 2.3 miles south-east) nearby, there’s older building stock in the area around Istead Rise as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
In the older streets around Saint Barnabus Church, the joint between an old wall and a newer frame is usually the first place rain gets in. If you look after a building such as Istead Rise Primary School, the mastic around its windows and doors needs looking after like any other building’s.

FAQs for Istead Rise
I let a flat near Meopham station. Can you help?

Do you cover Istead Rise for sand mastic?

How long will you be here?
It depends on the size of the job, but as a guide it takes a few hours per window, depending on the condition of the joints. We will tell you when we quote.
Can you match the sealant colour?
In most cases you can choose. We will explain which colours are available and agree one before we start.
How much does sand mastic cost in Istead Rise?

Can old silicone round a sash window be swapped for sand mastic?
Usually, yes. With the silicone removed and the joint cleaned, sand mastic is applied by hand.
Will it make a mess?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we are done.
Can sand mastic be painted?
Sand mastic is normally left unpainted, as guidance on traditional windows advises. Ask us before decorating.
What happens if it’s left?
New sash windows are a major, costly change and on a listed home, consent may be needed. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. In a small place like Istead Rise, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Why us?
- Full insurance on every job
- Trusted Arbo and Everbuild sealants

Looking after it afterwards
To keep the joints looking good and working properly:
- Avoid heavy scraping on the mastic joint
- Clear gutters so water does not pour onto the windows
- Sort the mastic before the decorators arrive
- Inspect the joints round the windows every year or so
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.
