Frames and glazing around Cubitt Town
With historic houses such as Queen's House (about 1.1 miles south) nearby, there’s older building stock in the area around Cubitt Town as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. In a converted house or block, who looks after the windows depends on the lease, so check that before you book.
Rented homes near Canary Wharf station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Cubitt Town is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. For an older house near a landmark such as Christ Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Window mastic in Cubitt Town
Behind a thin line of old mastic there’s sometimes a deep void. Filling it with sealant alone leaves a joint that can’t move properly, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. If you’re dealing with cold air getting in at the frame edge and cracked sealant at the sill ends, we can help.
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 Cubitt Town.

Your questions about window mastic in Cubitt Town
Can you do window mastic in Cubitt Town?
Yes. Our work covers London and the South East, and Cubitt Town is part of that. You can ring 0345 464 0079 or email us and tell us what needs doing, and we’ll send you a clear quote.
Is parking a problem for a job in Cubitt Town?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Can you match the sealant to my frames?
Yes, in most cases. Tell us the frame colour when you get in touch and we’ll match it as closely as we can.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. Indoors, that normally means someone at home.
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.
Is it messy?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.
Can I add another job to the visit?
Yes. Just list everything you need.
Are you fully insured?
Yes. We’re fully insured, and we have been doing sealant work for more than 20 years.
Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.
When it is not the sealant
We will not take on work that will not last, so these are the limits:
- A sash or casement that won’t close properly
- Damp coming through the wall itself rather than the frame joint
- A door that needs adjusting, rehanging or new seals
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think.
Surfaces we seal
- Timber windows & doors
- uPVC windows
- Aluminium frames
- Window sills
- Patio & French doors
- Composite doors
Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
How the job changes by surface
Composite doors
An exposed front door gets wind-driven rain. Those corners get the most care.
Patio & French doors
Heavy door frames can move more than windows. A flexible sealant copes with that.
How it works
We bring everything the job needs with us, so there’s nothing for you to buy. Once we have agreed what’s being done, the area is protected and the work begins. It normally takes a morning for a couple of windows and a door. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Cubitt Town. It helps if you can point us to a visitor permit or a bay close to the door.
- 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.
How to prepare
- Let us know about parking restrictions
- Tell us about any previous sealing or DIY attempts
- Clear items away from the joints we are working on

Advice
What affects the quote in Cubitt Town
Every job gets its own quote. This is what makes a difference:
- Access and height
- Which sealant suits the joint
- The number and length of the joints
- How many areas need sealing
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.
Asking for a quote
Before you ask for a quote, have a think about:
- The problem you’ve noticed
- How many joints, rooms or windows are involved
- If someone has resealed it before
- Pictures of the joints, sent by email
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.
Places near Cubitt Town
What else we do in Cubitt Town
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Wash the frames with mild soapy water
- Check the mastic once a year
- Keep paint and stain on wooden frames in good order
- Don’t aim a pressure washer at the joints
Wipe the frames with soapy water when you clean the windows, and avoid solvent cleaners on the sealant.
On timber windows, water behind the joint can lead to rot. Once wood has rotted, it needs repair before it can be sealed, so early resealing is worth it.
