Sand mastic for homes and businesses in Dyer's End
For a listed home or one in a conservation area, ask your local planning authority if consent is needed before window work. Like-for-like sand mastic is often the preferred finish. Common call-outs are for open joints round the window box and crumbling sand mastic round a window, across period & listed homes, sash and case windows and brick reveals.
Mastic can only go onto a dry, clean joint, so window work in Dyer's End is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Every job is covered by a one-year guarantee.

Honest limits
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Damaged stone surrounds
- Planning or listed building consent (your local planning authority decides)
- Putty and glazing repairs
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think before booking.

Frames and glazing around Dyer's End
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Hedingham Castle (about 4.4 miles south-east) are a reminder that the area around Dyer's End has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
For an older house near a landmark such as Parish Church of St Peter and St Thomas, the joint between an old wall and a newer frame is usually the first place rain gets in.

FAQs for Dyer's End

How do I get a quote for sand mastic in Dyer's End?
Size, access and the old material all affect the cost. Call for a quick quote and we will talk you through it.
Can I do it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Is it OK to seal over old sealant?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator and we are fully insured too.
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Work for landlords, hotels and businesses
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.
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Surface by surface
Sash and case windows
Most of our sand mastic work is on sash windows. Each joint round the box is raked out and renewed.
Period and listed homes
Materials matter on listed and conservation-area homes. Sand mastic is often the preferred finish.
What we’re called out for in Dyer's End
Over the years, sand mastic weathers. It hardens, cracks and starts to come away on the stone or timber.
Most people get in touch when they notice something like this:
- Gaps round a timber door in stone or brick
- Gaps where the frame meets the masonry
- Failed mastic on an exposed elevation
- Silicone on a period window that looks wrong
In and around Dyer's End, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

The process
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. Once we have agreed what’s being done, we protect the area and start. Most jobs take a few hours per window, depending on the condition of the joints. For a village or hamlet like Dyer's End, 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.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.
Preparing for the visit
- Clear the area around the work
- Let us know if you’ve seen damp or leaks
- Tell us if parking is tricky
