Sand mastic in Canning Town, done properly
Sand mastic doesn’t last for ever and gaps open up round the frame. Renewing it closes the gap and tidies the surround. If you have window mastic to renew ahead of painting and cracked mastic round a front door frame, we can help, whatever the surface.
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, which is when draughts and damp patches appear in homes in Canning Town.
The work is covered for a year after we finish. If anything isn’t right with it, phone 0345 464 0079 or email us.

Why deal with it now?
Not every draught comes from the sashes themselves. Open mastic joints round the box can let air in and new mastic seals them. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we will go through it with you.

When it is not the sealant
We will not take on work that will not last, so here’s what sealant can’t put right:
- Planning or listed building consent (your local planning authority decides)
- Timber that has rotted
- Sash cords, weights and draught-proofing of the sashes
If in doubt, call 0345 464 0079 or send us an email and we will say what we think.

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. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Managing a site like Rosetta Primary School? Then the mastic around its windows and doors needs looking after like any other building’s. Letting a property close to Custom House station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.

The process
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the work takes anything from a few hours to a full day, depending on how many windows in most cases. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic isn’t too thick.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
Preparing for the visit
- On commercial sites, let us know about site rules

Should I try it myself first?
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.
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.
What affects the cost of sand mastic
For a quick quote, just ask. The main things that affect it are:
- The number of rooms or windows
- How easy the joints are to reach
- Whether there’s mould to deal with
- The type of sealant required
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.
Helping us quote
Photos by email are helpful but not essential. Please mention:
- How we’d reach the joints
- The type of property
- How many joints, rooms or windows are involved
- Pictures of the joints, sent by email
It all starts with a short chat. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. When it suits you, phone 0345 464 0079 or email us.
Canning Town questions
Do you cover Canning Town for sand mastic?
Yes, Canning Town is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear price.
Do you work for landlords with property near Custom House station?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.
When will the new mastic be hard?
Not straight away. The skin forms first, and the full set comes later, and we will tell you what to expect.
Do I need permission for sand mastic on a listed building?
Check with your local planning authority. They’ll tell you if consent is needed for work to your windows.
Which products do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
What is sand mastic?
It’s a mix of sand and a linseed-oil-based binder. It’s built up in the joint by hand and finished to sit neatly against the masonry.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Can you work on commercial sites?
Yes, regularly. Larger jobs can be planned room by room or area by area.
What we’re called out for in Canning Town
Scraping and sanding before painting can loosen old mastic. Many people find it crumbling when they prepare the windows.
The problems people usually mention when they call include:
- Weathered mastic on the most exposed windows
- Open joints round the window box
- A silicone bead on a sash window that spoils the look
- Wind and rain getting in round a sash window
In the older streets around St Cedd's Church, the joint between an old wall and a newer frame is generally the first place rain gets in.
What your quote should include
- How the surfaces are prepared before sealing
- Whether they’re fully insured
- Whether all the old sealant comes out first
- How the colour is chosen
