About our sand mastic in Widley
Sand mastic does not last for ever and gaps open up round the frame. Renewing it closes the gap and tidies the surround. We work on stone surrounds, timber door frames and period & listed homes, and common reasons people get in touch are gaps where the frame meets the masonry and gaps round a timber door in stone or brick.
Around Widley, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
A one-year guarantee comes with the work, just as it does everywhere we cover.

FAQs for Widley
Will you come out to Widley?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is sand mastic in a coastal place like Widley any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll tell you what we are using.
How long does sand mastic take?
Typically it takes a few hours for a single window, longer for several. Larger jobs naturally take longer, and we will tell you how long to expect.
Can you quote for more than one area?
Yes, we can. More than one area can go on one quote.
Can new sealant go over the old?
No, because it fails. The old sealant always comes out first.
Do I need permission for sand mastic on a listed building?
Your local planning authority is the one to ask. They’ll tell you if consent is needed for work to your windows.

Why it’s worth doing now in Widley
Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic is the traditional material and finishes neatly against the masonry. Around Widley, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference.
What you get with us

Frames and glazing around Widley
Widley is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you live in an older home near Christ Church, the joint between an old wall and a newer frame is usually the first place rain gets in. If you look after a building such as Purbrook Park School, its window and door frames need their mastic kept sound, just like a home’s.
Widley is about 1 mile south-west of Purbrook, in Hampshire. Every kind of property in Widley is covered for sand mastic, old or new, large or small. The work is guaranteed for a year. 683 places in Hampshire are on our list.

What we do, step by step
The work is kept neat and contained to the joints we are treating. The job usually takes anything from a few hours to a full day, depending on how many windows, and we explain the cure time before we leave. Somewhere as small as Widley, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we look at the surrounds with you and agree what needs doing.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Mention any sign-in or site rules at work premises
- Tell us about any previous sealing or DIY attempts

Landlord and commercial work in Widley
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
Do you need sand mastic in Widley?
Shallow joints are a common cause. Mastic that’s too thin cracks and drops out so we make sure the new mastic is the right thickness.
The problems people generally mention when they call include:
- Weathered mastic on the most exposed windows
- Gaps where the frame meets the masonry
- Window mastic to renew ahead of painting
- Draughts and rain around sash boxes
If you let a flat or house near Cosham station, older sash windows in a rental need their mastic kept sound to keep the weather out.
Before booking anyone
- Whether they’re fully insured
- Is VAT in the price?
- What product goes in the joint
- How long to leave it before use
Should I try it myself first?
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.
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
