Window Mastic in Limehouse

Window mastic for homes and businesses in Limehouse
The mastic around a window or door seals the gap between the frame and the wall. When it cracks, hardens or pulls away, draughts and rain get in. The old mastic is removed and the joint resealed with a flexible exterior sealant. We work on uPVC windows, patio & French doors and composite doors, and common reasons people get in touch are whistling draughts around closed windows and rain getting in at the frame or under the sill.
From mansion-block windows to modern glazing in new flats, London has every kind of frame. Over the years, the sealant around them shrinks, cracks and pulls away, letting in draughts and water.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

Windows and doors in Limehouse
In a converted house or block, who looks after the windows depends on the lease, so it’s worth checking before booking. With historic houses such as Sutton House (about 2.4 miles north) nearby, there’s older building stock in the area around Limehouse as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Limehouse 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 Limehouse station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

What’s near Limehouse
Locally, jobs take us to homes and businesses close to St Paul's Way Trust School, Stepney Green Mathematics and Computing College and Star Of The East Public House and the streets around them. Limehouse has its own railway station: Limehouse station. A little further out are Surrey Quays Shopping Centre (1.6 miles south-west) and Tower of London (2 miles west). Not far away are St. James's Park Lake and Tower Hill.
Landlords, agents and businesses in Limehouse
Hotels need rooms back in use, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
What we are called out for in Limehouse
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 cannot flex. Backing rod sets the right depth.
If you can see any of these, it’s time to have the joints looked at:
- Rushed sealant from a window installation
- Leaking joints at the ends of sills
- Mastic that’s falling out in pieces
- Water coming in at the bottom corners of a door
If you live in an older home near St Paul's Bow Common, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Before booking anyone

When it is not the sealant
Some problems need a builder, plumber or other trade rather than us:
- Rotten timber, which needs a joiner first
- Faulty window hardware
- Damp problems in the wall away from the window
If in doubt, phone 0345 464 0079 or email us and we will say what we think.
Surfaces we seal
- Patio & French doors
- Composite doors
- Window sills
- uPVC windows
- Aluminium frames
- Timber windows & doors
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Make sure the drainage slots aren’t blocked
- Do not aim a pressure washer at the joints
- Keep solvents and bleach off the sealant
- Clean frames with a soft cloth and soapy water
Wipe the frames with soapy water when you clean the windows, and keep solvents and harsh chemicals off the joint.
Leaks generally show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
Common questions in Limehouse
Can parking be tricky for a visit in Limehouse?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.
I let a flat near Limehouse station. Can you help?
Yes, rental work is part of what we do. 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 we start.
Can you quote for more than one area?
Yes. More than one area can be quoted together.
Are you insured?
Yes. We are fully insured, and we can confirm the details when we quote.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
When is the sealant fully cured?
That depends on the sealant used, so follow the cure time we give you.
Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first.
Why act early in Limehouse
A cracked joint around a frame lets rain into the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. Resealing now is a small job by comparison. In a flat in Limehouse, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.
Why Limehouse clients choose us
- A 12-month guarantee on all work
- Arbo and Everbuild products
- White, clear, grey or coloured to suit, where the product allows
- ARBOMaster approved applicator
