What we do, step by step
There is not much for you to do on the day. Show us the job and we will take it from there. The job generally takes a few hours for a single window, longer for several, including the tidy-up. Somewhere as small as Atherfield Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- 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.
Getting ready for the visit
- On commercial sites, let us know about site rules
- Tell us about any water getting in
- Tell us about access, such as stairs, a lift or high-level joints

How we handle sand mastic in Atherfield Green
Our applicators renew the sand mastic around sash and case windows and doors in stone and brick. Out comes the old, loose mastic, and new mastic is applied and shaped by hand. If you’re dealing with gaps between timber frames and stone or brick and modern sealant on a period surround, we can help.
Mastic can only go onto a dry, clean joint, so window work in Atherfield Green is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
All our work comes with our 12-month guarantee, wherever you are in the Isle of Wight.

Atherfield Green homes and the weather
Atherfield Green is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around older windows and doors, especially on the side facing the sea. Historic houses like Wolverton Manor (about 2 miles north-west) are a reminder that the area around Atherfield Green 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.
Historic houses such as Wolverton Manor, about 2 miles north-west, show how far back building around Atherfield Green goes, and older homes nearby need a sealant that suits their walls.

FAQs for Atherfield Green
Does living near the coast affect sand mastic in Atherfield Green?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Is Atherfield Green 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.
Is it messy?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Can old silicone round a sash window be swapped for sand mastic?
Often, yes. With the silicone removed and the joint cleaned, sand mastic is applied by hand.
Can landlords and businesses book you?
Yes. Domestic, commercial and hotel work are all part of what we do, and we’re fully insured.
What does sand mastic cost?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before we start.
What sealant do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we’re using.
Do you guarantee sand mastic work?
You get our one-year guarantee on every job.
Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Check with your local planning authority if your home is listed
- Don’t run silicone over sand mastic
- Ask a joiner to look at soft timber first
- Clear gutters so water doesn’t pour onto the windows
Avoid painting over the new mastic, which is the traditional advice. Ask us before any decorating around it.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.

- If it’s domestic, commercial or a hotel
- How we’d reach the joints
- The rough size of the job

Why deal with it now?
New sash windows are a major, costly change, and in listed buildings it may need consent. Where the frames are in good order, new mastic seals the surround. In a small place like Atherfield Green, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
Why us?
- Every job guaranteed for a year
- Anti-fungal silicone where joints get wet
- We leave the area clean and tidy
- Domestic, commercial and hotel work

Signs you need sand mastic in Atherfield Green
Previous repairs in cement or silicone often trap water or crack away. They don’t suit the joint, and they generally need raking out.
Most people get in touch after spotting one of these:
- Mastic dropping out of the joint
- Cement or filler used on old window joints that has cracked
- Gaps between timber frames and stone or brick
- Mastic round period door frames that has failed
In and around Atherfield Green, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.
