Sand mastic in Hunny Hill, done properly
Traditional burnt sand mastic blends with stone and brick surrounds. It’s a good fit for period properties where a modern sealant bead would stand out. If you’re dealing with window mastic to renew ahead of painting and weathered mastic on the most exposed windows, we can put it right.
Many houses in smaller places like Hunny Hill have conservatories, garden rooms or patio doors. Their glazing joints and frame seals are as much a part of the job as the windows.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

What sand mastic looks like in Hunny Hill
Historic houses like Carisbrooke Castle (about 1.3 miles south-west) are a reminder that the area around Hunny Hill 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. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Carisbrooke Castle, about 1.3 miles south-west, is one of the historic houses in the wider area around Hunny Hill. For site and facilities teams at buildings such as Hunnyhill Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

Why it’s worth doing now in Hunny Hill
New mastic over crumbling mastic will not hold. We remove the loose material first so the new work lasts. Homes in smaller places like Hunny Hill can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.

How to look after the new joints
Good habits help new joints last longer. A few tips:
- Check the mastic when you check the paintwork
- Keep sills and gutters clear so water drains away
- Avoid patching sand mastic with silicone
- Ask a joiner to look at soft timber first
When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber and timber that stays wet can rot.

Mouldy or split sealant often shows up at the end of a tenancy. Several properties can go on one quote.
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Common questions in Hunny Hill
Is there a guarantee on sand mastic in Hunny Hill?

Is Hunny Hill in your area for sand mastic?
Yes, Hunny Hill is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or drop us an email and tell us what needs doing.

Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.

Can you match the sealant colour?
We’ll suggest a colour to suit the surroundings. The product needed can limit the range.
How long will you be here?
As a guide, most jobs take a few hours per window, depending on the condition of the joints. Larger jobs naturally take longer, and we will tell you how long to expect.
Can sand mastic be painted?
Traditional guidance is not to paint over sand mastic. If you are redecorating the window, ask us first and we will talk you through it.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
How it works
A visit follows a simple pattern: we check the joints, protect the area around them, do the work and clear up. Most jobs take anything from a few hours to a full day, depending on how many windows. Parking around Hunny Hill is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
