Sand mastic for homes and businesses in Chilbolton
We renew sand mastic around sash windows and doors in stone and brick. The old mastic is raked out, the joint is prepared and new mastic is shaped by hand. We’re often asked to deal with mastic dropping out of the joint and mastic worn away on windows facing the weather, across sash and case windows, period & listed homes and stone surrounds.
Mastic can only go onto a dry, clean joint, so window work in Chilbolton is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

The process
At the end, we look at the finished work together. The work normally takes a few hours per window, depending on the condition of the joints, depending on the size of the job. Somewhere as small as Chilbolton, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Getting ready for the visit

Advice
What affects the quote in Chilbolton
There’s no set price list, because jobs vary so much. The quote depends on:
- Any mould that needs treating
- The product the joint needs
- Whether old sealant or filler has to be cut out
- Whether the work is at height
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, phone 0345 464 0079 or email us for an honest opinion and a quote.
What we need to know
Before you ask for a quote, have a think about:
- How many joints, rooms or windows are involved
- Any access issues, like height or stairs
- Whether it has been sealed before
- Pictures of the joints, sent by email
If you are in Chilbolton and need sand mastic, ring 0345 464 0079 or drop us an email. A short description of the job and where it is helps us quote, and we’ll agree the price before any work begins.
What we can’t put right
We will not take on work that will not last, so here’s what sealant cannot put right:
- Sashes that rattle, stick or won’t open
- Decayed frames that need repair
- Planning or listed building consent (your local planning authority decides)
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly.
Surfaces we seal
- Tenement windows
- Timber door frames
