Sand mastic in Hillyfields, done properly
Burnt sand mastic is a traditional material blends with stone and brick surrounds. It suits period and listed homes where a modern sealant bead would stand out. If you’re dealing with mastic worn away on windows facing the weather and old sand mastic that has cracked, crumbled or fallen out, we can put it right, on timber door frames, sash and case windows and brick reveals alike.
In a smaller place like Hillyfields, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. The mastic around frames on those walls tends to age faster.

FAQs for Hillyfields
Can you help a landlord with a rental near Redbridge station?
Yes, we work for landlords and letting agents. You can phone 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before we start.
Is sand mastic in a coastal place like Hillyfields any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Is consent needed for window work on a listed home?
It’s best to ask your local planning authority first. Sand mastic is often favoured as like for like but the decision is theirs.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status.
What exactly is sand mastic?
Sand plus a binder based on linseed oil. It’s applied by hand and finished to sit neatly against the masonry.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
Can you seal over the old sealant?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. We remove it all first.
What sand mastic looks like in Hillyfields
Hillyfields is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. Historic houses like Southampton Tudor House and Garden (about 3.7 miles south-east) are a reminder that the area around Hillyfields has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Homes close to All Saints include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame. Schools such as Holy Family Catholic Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

What we do, step by step
A visit follows a simple pattern: we check the joints, protect the area around them, do the work and tidy away. Most jobs take a few hours for a single window, longer for several. In a smaller place like Hillyfields, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- Each surround is checked first.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic isn’t too thick.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Let us know about earlier repairs to the joints
- Move anything stored near the joints

What we’re called out for in Hillyfields
Previous repairs in cement or silicone often trap water or crack away. They don’t suit the joint, and they generally need raking out.
If you can see any of these, it’s time to have the joints looked at:
- Window mastic to renew ahead of painting
- Crumbling sand mastic round a window
- Mastic round period door frames that has failed
- Weathered mastic on the most exposed windows
Letting a property close to Redbridge station? Then any sash windows need sound mastic to keep draughts and rain out.
What to look for in a quote
- Whether all the old sealant comes out first
- What product goes in the joint
- What preparation is included
- Whether you can choose the colour
Leave it or put it right?
If you’re redecorating, renew the mastic first. Painting over failed mastic doesn’t seal it, and the new mastic is traditionally left unpainted. Around Hillyfields, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.
