How we handle sand mastic in Mill Meads
Silicone on a period window often looks wrong and does not suit the building. Sand mastic is the traditional choice and we can swap the silicone for it. We work on tenement windows, period & listed homes and sash and case windows, and the jobs we see most are silicone on a period window that looks wrong and tired mastic found when preparing windows for paint.
London has a lot of flats and conversions, where windows are often on upper floors. In a converted house or block, the lease generally says who is responsible for the windows, so it’s worth checking before booking.
You are covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

Mill Meads homes and the weather
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 Sutton House (about 2.4 miles north-west) are a reminder that the area around Mill Meads has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
For site and facilities teams at buildings such as East London Science School, the mastic around its windows and doors needs looking after like any other building’s. As a London address, Mill Meads can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Why deal with it now?
Replacing sash windows is a big decision for a period home and on a listed home, consent may be needed. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we will explain what it covers.

Signs you need sand mastic in Mill Meads
Age is the main cause. Sand mastic is a maintenance item like any pointing, depending on exposure and upkeep.
Look out for these signs:
- Old sand mastic that has cracked, crumbled or fallen out
- Window mastic to renew ahead of painting
- Gaps round a timber door in stone or brick
- Draughty sash windows at the surround
Rented homes near West Ham station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.
Questions to ask before you book
- Who does the work, and how experienced they are
- The length of the guarantee
- How hidden problems are handled
- Whether VAT is included
Aftercare tips
A little care helps the new joints last. We recommend:
- Keep modern sealant off the mastic
- Sort the mastic before the decorators arrive
- Make sure water runs off the sill
- Have rotten timber repaired before new mastic goes in
Check the mastic when you check the paintwork. Catching cracks early keeps repairs small.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
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, then guaranteed for a year.
Mill Meads questions
Is parking an issue for sand mastic in Mill Meads?
Parking in Mill Meads, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
I let a flat near West Ham station. Can you help?
Yes, we work for letting agents and landlords. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before any work starts.
Will the old sealant be removed?
Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Can sand mastic be painted?
Sand mastic is normally left unpainted, which is what traditional guidance recommends. Talk to us before any painting near it.
Is it messy?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
How much does sand mastic cost in Mill Meads?
We don’t 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 will get a clear quote before work begins.
What information do you need?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply phone 0345 464 0079 or email us.
What we do, step by step
When we arrive, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before any work begins. The work generally takes a few hours for a single window, longer for several. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Mill Meads. It helps if you can point us to a visitor permit or a bay close to the door.
- 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.
- 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.
Getting ready for the visit
- Keep children and pets away from the work area
- Tell us about any previous sealing or DIY attempts
- Mention any sign-in or site rules at work premises
