Bush Hill Window Mastic
Problem with your window and door frames in Bush Hill? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Leaking joints at the ends of sills
- Rushed sealant from a window installation
- Draughty joints inside around the window
What we do, step by step
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a morning for a couple of windows and a door. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Mention any parking rules near the property
- Move anything stored near the joints

Advice
Window mastic in Bush Hill
Homes in Bush Hill have every kind of window: from uPVC casements to timber and aluminium, along with patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. We work on timber windows & doors, uPVC windows and composite doors, and the jobs we see most are mastic that has split away from the wall and draughty joints inside around the window.
London’s Victorian and Edwardian terraces were built with timber sash windows, and many still have them or their replacements. Whatever is in the opening now, the joint between frame and wall is what keeps the weather out, in Bush Hill as anywhere.
The work is covered for a year after we finish. If anything isn’t right with it, call 0345 464 0079 or email us.

Common problems we fix in Bush Hill
Sills take more water than any other part of a window, so the sill ends and the joint below the frame are common leak points. Failed sealant there lets rain into the wall or behind the frame.
It’s worth asking for a quote if you see:
- Hard, cracked sealant around windows
- Old mastic that has gone black or come away
- Damp patches on the reveal after heavy rain
- A bead that doesn’t match the frame
As a London address, Bush Hill can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Landlords, agents and businesses in Bush Hill
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.
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.
When it isn’t the sealant
Sealant is not the answer to every problem, and we’ll tell you before any work starts. Sealant will not put right:
- Condensation trapped between the panes
- Damp problems in the wall away from the window
- 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.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Check the mastic once a year
- Ventilate rooms so frames don’t stay wet inside
- Clean frames with a soft cloth and soapy water
- Do not use solvent cleaners on the joint
Keep sill grooves and drainage slots clear, so water can run away instead of sitting against 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.
Why deal with it now?
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 London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler for homes in Bush Hill.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

Common questions in Bush Hill
Do you cover Bush Hill for window mastic?
Yes, Bush Hill is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear price.
Is parking a problem for a job in Bush Hill?
Parking in Bush Hill, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
Is it OK to seal over old sealant?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
Do I need to be at home?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
I’m a tenant. Can you help?
We can work for tenants, landlords or agents. Just make sure your landlord agrees.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.
How long does it take to reseal the windows on a house?
A few frames take a few hours. You will get a timescale with the quote.
What do you need from me for a quote?
Let us know what needs doing and where, with pictures by email if possible. If we need more, we will ask.
Should I try it myself first?
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Window mastic in Bush Hill: local notes
In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking. With historic houses such as Forty Hall (about 2.1 miles north) nearby, there’s older building stock in the area around Bush Hill as well as newer homes. 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.
For landlords with property near Grange Park station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. For an older house near a landmark such as Grange Park Methodist Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
