Swingfield Minnis Sand Mastic
Our applicators work in Swingfield Minnis on traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old sealant removed completely, joints prepared properly and a one-year guarantee.
- Crumbling sand mastic round a window
- Draughty sash windows at the surround
- Mastic round period door frames that has failed
Sand mastic in Swingfield Minnis, done properly
Burnt sand mastic is a traditional material that sits naturally against stone and brick. It’s a good fit for period properties where a modern sealant bead would stand out. If you have cracked mastic round a front door frame and a silicone bead on a sash window that spoils the look, we can put it right.
Homes in small places like Swingfield Minnis often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
The work is covered for a year after we finish. If anything is not right with it, call 0345 464 0079 or send us an email.

Why it’s worth doing now in Swingfield Minnis
Gaps round a sash window let in rain and draughts. Left, water can reach the timber and the wall so renewing it early protects the window. Older cottages and farmhouses around Swingfield Minnis can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or drop us an email and we’ll talk you through it.

What affects the cost of sand mastic
We quote each job individually. This is what makes a difference:
- Mould in or behind the old joints
- The product the joint needs
- The size of the job
- The number of rooms or windows
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
What we need to know
What to tell us when you ask for a quote:
- Whether it’s a home or a business
- Access, such as stairs, a lift or height
- Any previous sealing or DIY work
- The rough size of the job
Every job is quoted individually. Just ring 0345 464 0079 or email us with the details, and photos are welcome.
DIY versus a professional finish
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.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

Advice
When to call us in Swingfield Minnis
Shallow joints are a common cause. A thin layer doesn’t hold well, which is why we pack deep voids first and get the depth right.

- Mastic round period door frames that has failed
- Weathered mastic on the most exposed windows
- Gaps where the frame meets the masonry
- Window mastic to renew ahead of painting
If you let a flat or house near Shepherds Well station, any sash windows need sound mastic to keep draughts and rain out.
What to look for in a quote
- Whether they seal over old material or remove it
- Which sealant they’ll use, and why
- Is VAT in the price?
- How hidden problems are handled
How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Ask a joiner to look at soft timber first
- Clear gutters so water does not pour onto the windows
- Check the mastic when you check the paintwork
- Avoid patching sand mastic with silicone
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber and timber that stays wet can rot.
Work for landlords, hotels and businesses
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we’ll quote.
