Window Mastic in Canning Town
Mastic around window and door frames, sills and patio doors for homes and businesses in Canning Town and across Greater London. Fully insured, ARBOMaster approved and guaranteed for a year.
- Untidy mastic left by window fitters
- Black, perished sealant on frames
- Cracked internal joints between frame and plaster
Window mastic for homes and businesses in Canning Town
Most frames have an outside joint and an inside one. Outside, the mastic keeps rain out; inside, the joint between frame and plaster stops draughts and tidies the reveal. Either or both can be done. Typical jobs include rushed sealant from a window installation and whistling draughts around closed windows, on uPVC windows, timber windows & doors and aluminium frames.
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 Canning Town as anywhere.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

Do you need window mastic in Canning Town?
Joint shape matters as much as the product. A thin smear across a wide gap has nothing to it, while a joint packed solid can’t stretch. Backing rod sets the right depth.
Look out for any of the following:
- Whistling draughts around closed windows
- Gaps between the frame and the inside reveal
- Sealant in the wrong colour for the frame
- Hard, cracked sealant around windows
Managing a site like Rosetta Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.

Quotes for window mastic in Canning Town
Your quote is based on your job. We look at:
- The amount of work
- Mould in or behind the old joints
- The type of sealant required
- When we can work, for business premises
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
What we need to know
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- How many joints, rooms or windows are involved
- Photos by email, if that’s easy
- Any access issues, like height or stairs
- The address or postcode of the job
We do not publish a price list, as no two jobs are quite the same. Instead, we send you a clear quote for your job. To get started, ring 0345 464 0079 or send us an email.
What we cannot put right
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Penetrating damp from a failed cavity tray or render
- Draughts through the window seals rather than the frame
- Soft or decayed wood in the frame
If you’re not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer before you book.

Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Keep solvents and bleach off the sealant
- Repaint timber before it’s bare
- Paint up to the joint, not over it
- Air rooms to keep condensation down around windows
Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.
Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.
Frames and glazing around Canning Town
In a converted house or block, who looks after the windows depends on the lease, so check that before you book. Historic houses like Queen's House (about 2.7 miles south-west) are a reminder that the area around Canning Town has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Canning Town is in London, so parking needs planning: let us know about parking bays, permits or a driveway. If you let a flat or house near Custom House station, renewing tired window mastic between tenants heads off draught and damp complaints.

Canning Town questions
Is parking a problem for a job in Canning Town?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Do you cover Canning Town for window mastic?
Yes, Canning Town is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or email us and tell us what needs doing.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
Do you work for hotels and businesses?
Yes. Larger jobs can be planned room by room or area by area.
I’m a tenant. Can you help?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
Can new window sealant be painted?
That depends on the product. Some hybrid sealants can be painted; silicone cannot. Mention any painting plans before we start.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
How much does window mastic cost in Canning Town?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before we start.

Other services in Canning Town
Why deal with it now?
Not every sealant suits a window. Interior caulk and bathroom silicone aren’t made for exterior frame joints. An exterior, low-modulus sealant stays flexible in sun and frost. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and agree the price before starting.

What we do, step by step
There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours for a handful of frames, longer for a whole house in most cases. For a job in Canning Town, parking and access are the things to plan: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- 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.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
Preparing for the visit
- Clear items away from the joints we’re working on
- Tell us about access, such as stairs, a lift or high-level joints
- For indoor joints, keep the area dry beforehand if you can
