Sand mastic for sash & case windows in Broughton, Milton Keynes
Problem with your window and door surrounds in Broughton? We remove the old material, prepare the joints and seal them properly.
- Modern sealant on a period surround
- Wind and rain getting in round a sash window
- Mastic that needs renewing before redecorating
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.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Sand mastic for homes and businesses in Broughton
Burnt sand mastic is a traditional material blends with stone and brick surrounds. It’s a good fit for period properties where a modern sealant bead would stand out. We are often asked to deal with failed mastic on an exposed elevation and draughty sash windows at the surround, across tenement windows, period & listed homes and timber door frames.
Many houses in smaller places like Broughton have conservatories, garden rooms or patio doors. Those joints need the same attention as the main windows, and any older timber or sash windows need a sealant that suits them.
We stand behind the work with a one-year guarantee.

How it works
We bring everything the job needs with us, so there’s nothing for you to buy. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes anything from a few hours to a full day, depending on how many windows. For a job in Broughton, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First, we look at the surrounds with you and agree what needs doing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Preparing for the visit
- Tell us about any water getting in
- Mention any tricky access
- Let us know about parking restrictions

Windows and doors in Broughton
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Linford Manor (about 3.1 miles north-west) are a reminder that the area around Broughton has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
For site and facilities teams at buildings such as Broughton Fields Primary School, the mastic around its windows and doors needs looking after like any other building’s. In the older streets around St Lawrence's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Leave the new mastic unpainted
- Keep sills and gutters clear so water drains away
- Check with your local planning authority if your home is listed
- Don’t run silicone over sand mastic
When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.
Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger.
