About our sand mastic in Hillway
Sand mastic doesn’t last for ever, leaving gaps round the window. We rake it out and renew it and tidies the surround. If you have weathered mastic on the most exposed windows and tired mastic found when preparing windows for paint, we can help.
Around Hillway, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Sand mastic in Hillway: local notes
Hillway is within about 1 mile of 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. With historic houses such as Yaverland Manor (about 1.6 miles west) nearby, there’s older building stock in the area around Hillway 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.
Schools such as Bembridge Church of England Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. If you live in an older home near Bembridge Methodist Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

For landlords and businesses

We work for landlords and letting agents as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.
What affects the cost of sand mastic
The price is agreed before any work begins. It’s based on:
- How much old sealant there is and how hard it is to remove
- The size of the job
- How many areas need sealing
- The product the joint needs
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, phone 0345 464 0079 or email us for an honest opinion and a quote.
What to tell us for a quote
When you call or email, these details help:
- The address or postcode of the job
- Photos by email, if that’s easy
- Whether it’s a home or a business
- Any previous sealing or DIY work
Asking for a quote is easy: let us know what needs doing and where, and roughly how big it is. A few pictures by email make the job easier to understand.
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 the joint depth matters as much as the finish.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Questions from Hillway
Do you work for landlords with property near Brading station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll send you a clear quote.
Is Hillway within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status.
Is it OK to seal over old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
Can you quote for more than one area?
Yes. Just list everything you need.
Should I check with the council before work on a listed or conservation-area home?
Checking first is sensible. Your local planning authority can say if consent is needed for work on a listed home or in a conservation area.
How long does sand mastic take?
A typical job takes a few hours for a single window, longer for several. Your quote will say how long we expect yours to take.
Are you insured?
Yes, we are fully insured.
The process
Once we are on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a single window, longer for several. For a village or hamlet like Hillway, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We check the window surrounds and agree which joints need renewing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The mastic is finished to sit tidily against the stone or brick.
Before we arrive
- Move anything stored near the joints
- Where the joints are inside, avoid wetting them before we arrive
- Mention any leaks or damp you’ve noticed

When to call us in Hillway
Shallow joints are a common cause. Mastic that’s too thin cracks and drops out, which is why we pack deep voids first and get the depth right.
Most people get in touch when they notice one of these:
- Failed mastic on an exposed elevation
- Crumbling sand mastic round a window
- Draughty sash windows at the surround
- Patchy fillers round a sash window
For landlords with property near Brading station, cracked sand mastic around sash windows lets in the draughts tenants complain about.
Before you book anyone
- How long to leave it before use
- How long the guarantee is
- What the quote includes, VAT included or not
- How the surfaces are prepared before sealing
Why deal with it now?
New mastic over crumbling mastic will not hold. Raking out and preparing the joint gives it a sound base so the new mastic stays put. Around Hillway, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.
