How we handle sand mastic in Hursley
Silicone on a period window often looks wrong and does not suit the building. Sand mastic gives a finish that matches the age of the house and we can swap the silicone for it. We work on stone surrounds, timber door frames and sash and case windows, and the jobs we see most are silicone on a period window that looks wrong and mastic worn away on windows facing the weather.
Mastic can only go onto a dry, clean joint, so window work in Hursley is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Whatever the size of the job, it’s backed by our 12-month guarantee in Hursley and across Hampshire.

Frames and glazing around Hursley
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Homes close to Church of All Saints include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you look after a building such as John Keble Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s.

What else we do in Hursley
Why act early in Hursley
An open joint round the frame lets weather in. Water can get to the frame and the masonry so renewing it early protects the window. Older cottages and farmhouses around Hursley can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

Hursley questions
Can you help a landlord with a rental near Shawford station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before work begins.
Is Hursley within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can I choose the sealant colour?
We help you choose a colour that suits. The product needed can limit the range.
How long does sand mastic take to harden?
Not right away. It skins first and hardens fully later and we’ll give you an idea for your job.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.
Can you replace silicone on a period window with sand mastic?
Yes, it’s a common request. All the old silicone is removed first so the mastic can sit properly.
Can I do it myself?
You can, for simple jobs. 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.
Where is Mr Mastic based?
We work from Crawley. Our applicators cover Hursley.

For a quote, call 0345 464 0079 or send us an email and tell us where the job is and what the problem looks like. We will give you a clear quote before any work starts.
Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What happens on the day
The work is kept neat and contained to the area we are working on, so you can carry on as normal. The job usually takes a few hours for a single window, longer for several, and we explain the cure time before we leave. Somewhere as small as Hursley, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each surround is checked first.
- The joint is raked out and cleaned.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Move anything stored near the joints
- Plan for the work area to be out of bounds to pets and children
