Sand mastic in Congelow, done properly
Our applicators renew the sand mastic around sash and case windows and doors set in stone or brick. The old mastic is raked out, the joint is prepared and new mastic is shaped by hand. We work on sash and case windows, tenement windows and brick reveals, and people most often call us about mastic round period door frames that has failed and wind and rain getting in round a sash window.
Homes in small places like Congelow 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.
All our work comes with our one-year guarantee.

What affects the quote in Congelow
We quote each job individually. These are the things that affect it:
- The number and length of the joints
- The number of rooms or windows
- Any working-time requirements on site
- The old material and how stubborn it is
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
What to tell us for a quote
When you call or email, it’s useful to know:
- Pictures of the joints, sent by email
- The rough size of the job
- Whether it’s a home or a business
- If someone has resealed it before

We regularly work with letting and managing agents. Tell us the address, the job and how access works and we’ll quote.
The process
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes anything from a few hours to a full day, depending on how many windows. For a village or hamlet like Congelow, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.

Advice

What else we do in Congelow
Why it’s worth doing now in Congelow
Before painting the windows, it pays to renew the mastic. Paint over cracked mastic will not stop the gaps, and the new mastic is traditionally left unpainted. Around Congelow, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
What it costs depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.

If you live in an older home near St Peter's and St Paul's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
