Your questions about sand mastic in Wembley Park
Is parking an issue for sand mastic in Wembley Park?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.

Should I check with the council before work on a listed or conservation-area home?
Your local planning authority is the one to ask. They’ll tell you if consent is needed.
Can you do several jobs on one visit?
Yes. Just list everything you need and you’ll get one quote.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
Do the sealants smell?
Some sealants have a smell while they cure, but it fades. Opening a window helps.

Sand mastic for homes and businesses in Wembley Park
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s made from sand and a linseed-oil-based binder and built up by hand. On period homes, it looks right where silicone wouldn’t. Common call-outs are for tired mastic found when preparing windows for paint and old cement repairs round a window that have failed, across timber door frames, stone surrounds and tenement windows.
From mansion-block windows to modern glazing in new flats, London has every kind of frame. The mastic around them dries out and cracks with age, letting in draughts and water.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or email us.

Windows and doors in Wembley Park
In a converted house or block, who looks after the windows depends on the lease, so it’s worth checking before booking. Historic houses like Pitzhanger Manor (about 3.8 miles south) are a reminder that the area around Wembley Park has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you look after a building such as Michaela Community School, the mastic around its windows and doors needs looking after like any other building’s. Rented homes near Wembley Stadium station change hands often, and any sash windows need sound mastic to keep draughts and rain out.

What affects the cost of sand mastic
Every job gets its own quote. This is what makes a difference:
- Working hours on commercial sites
- Whether the work is at height
- The number and length of the joints
- How many rooms, windows or areas are involved
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
What to tell us for a quote
There’s no need for technical detail. It helps if you can tell us:
- How we’d reach the joints
- The rough size of the job
- Pictures of the joints, sent by email
- Where the property is
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is. Whenever you’re ready, call 0345 464 0079 or drop us an email.

How the visit works
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it usually takes a few hours per window, depending on the condition of the joints. In Wembley Park, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose 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 finish is dressed so it sits neatly against the stone or brick.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about any previous sealing or DIY attempts
- Plan for the work area to be out of bounds to pets and children

Advice
Different surfaces, different methods
Tenement and terrace windows
Tenements and terraces often have many sash windows with ageing mastic. We work on single windows or whole elevations.
Sash and case windows
On a sash window, the mastic joint shows on the outside, so a neat, even finish matters.
Signs you need sand mastic in Wembley Park
Previous repairs in cement or silicone often trap water or crack away. They do not move with the timber and we normally remove them.
Signs it’s time to call us include:
- Cement or filler used on old window joints that has cracked
- Window mastic to renew ahead of painting
- Gaps between timber frames and stone or brick
- Modern sealant on a period surround
Wembley Park is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
What to look for in a quote
- Whether VAT is included
- When the joint can take water or movement
- Which colour the sealant will be
- How the surfaces are prepared before sealing
Should I try it myself first?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Work for landlords, hotels and businesses
Landlords and letting agents in Wembley Park can book us as well as homeowners. Sealant work between tenants keeps a property looking cared for.
