About our window mastic in Bickley
A cold draught around a closed window often comes from the frame edge. Resealing that joint can make a room feel noticeably less draughty and quietens the whistle on windy days. If the draught is through the window seals instead, we’ll tell you. If you have untidy mastic left by window fitters and black, perished sealant on frames, we can help, on composite doors, timber windows & doors and aluminium frames alike.
Many London homes are flats, with windows high above the street. In a converted house or block, the lease usually says who is responsible for the windows, so it’s worth checking before booking.
Our work is backed for twelve months.

What else we do in Bickley
Why act early in Bickley
Working on frames from a ladder with a sealant gun is not easy, especially on upper floors. A professional job is cut out properly, backed where needed and finished neatly, in a sealant suited to the wall. 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.
What it costs depends on how much there is to do, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts.

Common problems we fix in Bickley
On timber frames, paint and putty build up around the joint. Old mastic gets painted over and cracks under the paint, and timber moves with moisture as well as temperature.
Any of these means the joints need attention:
- Untidy mastic left by window fitters
- Gaps where the sill meets the wall
- Rain getting in at the frame or under the sill
- Sealant in the wrong colour for the frame
In the older streets around Church of St George, the joint between an old wall and a newer frame is generally the first place rain gets in.
What to look for in a quote
- Is the old sealant removed completely?
- What guarantee comes with the work
- How hidden problems are handled
- Whether the sealant suits the joint
Work for landlords, hotels and businesses
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
FAQs for Bickley
Is parking a problem for a job in Bickley?
Parking in Bickley, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
Is Bickley in your area for window mastic?
Yes. Our work covers London and the South East, and Bickley is part of that. You can phone 0345 464 0079 or send us an email and let us know what needs doing, and we’ll send you a clear quote.
How long before the joint can be used?
That depends on the sealant used, so please follow the time we give you when we finish.
Can I paint over the new sealant?
It depends on the sealant. Silicone is not paintable, but some hybrid sealants are. Tell us if you are decorating and we will choose accordingly.
Do you have insurance?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Can you match the sealant to my frames?
Usually, yes. Mention the frame colour when you ask for a quote and we’ll use the nearest match.
I’m a tenant. Can you help?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
Is it worth trying it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Wash the frames with mild soapy water
- Make sure the drainage slots aren’t blocked
- Keep jet washers away from the mastic
- Wipe condensation off the frames
Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and a cold room gets colder. A new joint closes it up.
The process
We bring everything the job needs with us, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes a few hours for a handful of frames, longer for a whole house. In a London area like Bickley, the main things to plan are parking and access: let us know about parking, the floor we will be working on and any lift or shared entrance.
- We check each frame and agree which ones need doing.
- The old mastic is cut out and the surfaces cleaned back.
- We fit backing rod in deep gaps so the sealant is the right depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- We clear up and check every joint is fully closed.
Before we arrive
- Move anything stored near the joints
- On commercial sites, let us know about site rules
- Let us know if you’ve seen damp or leaks

Related advice
Bickley homes and the weather
Historic houses like Bromley Palace (about 1.1 miles west) are a reminder that the area around Bickley 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. In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking.
Letting a property close to Bickley station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Managing a site like Bullers Wood School for Boys? Then larger buildings have plenty of frames, and the mastic around each one ages.
