Sand mastic in Steephill, done properly
If your home is listed or in a conservation area, check with your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. We work on period & listed homes, timber door frames and stone surrounds, and people most often call us about old cement repairs round a window that have failed and cracked mastic round a front door frame.
Outdoor sealant needs dry, clean surfaces, so work on frames around Steephill is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
The work is covered for a year after we finish. If anything is not right with it, call 0345 464 0079 or email us.

Steephill: your questions answered
Does living near the coast affect sand mastic in Steephill?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Is Steephill within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status, and we are fully insured.
How long does sand mastic take to go off?
A skin forms quite soon, but full hardening takes longer. We’ll explain what to expect before we leave.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done and you will get one quote.
How do I get a quote for sand mastic in Steephill?
Size, access and the old material all affect the cost. Ask us for a quote and we’ll talk you through it.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Is it possible to take out silicone and use sand mastic instead?
In most cases. We remove the silicone and clean the joint, then point it with sand mastic.
What we’re called out for in Steephill
Most of it is simply age. Sand mastic is a maintenance item like any pointing and how long it lasts depends on the weather it faces.
It’s worth asking for a quote if you see:
- Failed mastic on an exposed elevation
- Draughty sash windows at the surround
- Mastic round period door frames that has failed
- Patchy fillers round a sash window
Managing a site like St Francis Catholic and Church of England Primary Academy? Then its window and door frames need their mastic kept sound, just like a home’s.
Questions to ask before you book
- What happens if the job turns out different
- How the surfaces are prepared before sealing
- Whether VAT is included
- What guarantee comes with the work
Why it’s worth doing now in Steephill
Filling over old, loose mastic does not last. We remove the loose material first so the new work lasts. Where a wall is exposed, as many are in small places like Steephill, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
We do not show prices on the website, because each job is priced on what it involves. For a quick quote, please ring 0345 464 0079 or drop us an email and we will talk you through it.

What we do, step by step
Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes anything from a few hours to a full day, depending on how many windows, depending on the amount of work. In a small place like Steephill, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic is not too thick.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
Getting ready for the visit
- Clear items away from the joints we are working on
- Mention any leaks or damp you’ve noticed
- Try not to wet indoor joints just before the visit

What sand mastic looks like in Steephill
Steephill is close to 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. With historic houses such as Rylstone Manor (about 3.2 miles north-east) nearby, there’s older building stock in the area around Steephill 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 is traditional sand mastic.
If you let a flat or house near Shanklin station, cracked sand mastic around sash windows lets in the draughts tenants complain about. For an older house near a landmark such as Church of St. Alban-the-martyr, the joint between an old wall and a newer frame is generally the first place rain gets in.
Steephill is about 3 miles south-west of Shanklin, in the Isle of Wight.

What affects the cost of sand mastic
Every job gets its own quote. This is what makes a difference:
- The number of rooms or windows
- The number and length of the joints
- Working hours on commercial sites
- Any mould that needs treating
A failed joint rarely gets cheaper to fix by waiting. If you are not sure whether it needs doing, call 0345 464 0079 or email us and we will give you an honest view and a quote.
Helping us quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- The problem you’ve noticed
- If it’s domestic, commercial or a hotel
- If someone has resealed it before
- Where the job is, and your postcode
There’s no standard price list, because every job is different. Instead, your job gets its own clear quote. To arrange one, ring 0345 464 0079 or email us.
Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Go gently near the mastic when preparing windows
- Make sure water runs off the sill
- Plan mastic work ahead of painting
- Leave the new mastic unpainted
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.
DIY versus a professional finish
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.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
