About our sand mastic in Bierley
Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. We rake it out and renew it so the surround looks right again. We work on stone surrounds, period & listed homes and timber door frames, and people most often call us about weathered mastic on the most exposed windows and modern sealant on a period surround.
Mastic can only go onto a dry, clean joint, so window work in Bierley is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Common problems we fix in Bierley
Age is the main cause. Even well-laid mastic needs renewing in time, depending on exposure and upkeep.
The problems people usually mention when they call are:
- Wind and rain getting in round a sash window
- Weathered mastic on the most exposed windows
- Crumbling sand mastic round a window
- Mastic round period door frames that has failed
If you live in an older home near Church of St. Mary and St. Radegund, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
What to look for in a quote
- Which colour the sealant will be
- What the cure time is
- Is the old sealant removed completely?
- What guarantee comes with the work
When something else is needed
In fairness, there are a few things sealant won’t fix:
- Sash cords, weights and draught-proofing of the sashes
- Rotten sashes, sills or window boxes (a joiner’s job)
- Damaged stone surrounds
If you’re not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer.

How the visit works
Before we leave, we go over the finished joints with you. The work normally takes anything from a few hours to a full day, depending on how many windows, depending on the amount of work. For a village or hamlet like Bierley, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- Large voids are packed out first, so the mastic isn’t too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
How to prepare
- Tell us about any water getting in
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about stairs, lifts or work at height

Related advice
Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Frames and glazing around Bierley
Bierley is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. With historic houses such as Sheat Manor (about 4.1 miles north) nearby, there’s older building stock in the area around Bierley as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
For site and facilities teams at buildings such as Niton Primary School, its window and door frames need their mastic kept sound, just like a home’s. For landlords with property near Shanklin station, any sash windows need sound mastic to keep draughts and rain out.

What affects the quote in Bierley
The quote reflects the job in front of us. We look at:
- Any working-time requirements on site
- How much old sealant there is and how hard it is to remove
- The type of sealant required
- Any mould that needs treating
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
What we need to know
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- A few pictures by email, if you can
- Any access issues, like height or stairs
- Whether it has been sealed before
- Whether it’s a home or a business
Quotes start with a quick conversation. Describe the problem, the location and the size of the job. When it suits you, ring 0345 464 0079 or drop us an email.
Why act early in Bierley
New sash windows are a major, costly change and on a listed home, consent may be needed. Where the frames are in good order, new mastic seals the surround. In a small place like Bierley, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we’ll explain what it covers.
