Window mastic for homes and businesses in West Silvertown
Whether it’s one leaking patio door or every frame on the house, the work is priced before anything is done. Just ring 0345 464 0079 or drop us an email and tell us how many frames there are and how they’re reached. If you are dealing with white mastic on grey or black frames and hard, cracked sealant around windows, we can put it right.
London’s Victorian and Edwardian terraces were built with timber sash windows, and many still have them or their replacements. Either way, the mastic between frame and brickwork is what stops draughts and rain getting in, in West Silvertown as anywhere.
Big or small, you get the same one-year guarantee in West Silvertown and across Greater London.

Leave it or put it right?
Draughts and leaks do not always mean new windows. Where the frames are sound, new mastic normally deals with draughts and leaks at the edges. Problems with the glass or gaskets are for a window company, and we’ll say so. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler for homes in West Silvertown.

What else we do in West Silvertown
DIY versus a professional finish
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.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Frames and glazing around West Silvertown
Historic houses like Queen's House (about 2 miles south-west) are a reminder that the area around West Silvertown 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. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Schools such as Britannia Village Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. Homes close to St Barnabas' Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

The process
You don’t need to clear the whole room or building, just the space around the work. We protect the rest, and the job takes anything from an hour or two to a full day, depending on how many frames there are for a typical job. For a job in West Silvertown, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Preparing for the visit
- Mention any parking rules near the property
- Let us know about earlier repairs to the joints
- Let us know about stairs, lifts or work at height

How we quote for window mastic
The price is agreed before any work begins. It takes into account:
- How much old sealant there is and how hard it is to remove
- How many areas need sealing
- How much there is to do
- Mould in or behind the old joints
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Where the property is

We quote each job on its own. Just ring 0345 464 0079 or send us an email with the details.

FAQs for West Silvertown
Can you do window mastic in West Silvertown?
Yes, West Silvertown is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or drop us an email and let us know what needs doing.
Do you work for landlords with property near Custom House station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear price.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. Indoors, that usually means someone at home.
What information do you need?
The location, the problem and the rough size of the job. If you can, email a few photos.
Where do you work from?
Our base is in Crawley, and we work across South East England, London and Scotland.
How long before the joint can be used?
That depends on the sealant used, so please follow the time we give you.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Common problems we fix in West Silvertown
Joints that are too thin or too deep fail early. A skim of sealant over a wide gap soon tears, and a gap filled solid can’t flex. Backing rod sets the right depth.
People usually contact us when they notice something like this:
- Hard, cracked sealant around windows
- Water coming in at the bottom corners of a door
- Cracked internal joints between frame and plaster
- Sealant in the wrong colour for the frame
As a London address, West Silvertown can be tricky for parking: let us know about parking bays, permits or a driveway.
