How we handle window mastic in Hooley
Some gaps around frames are far deeper than they look. Packing it solid with sealant gives a joint that can’t flex, so deep gaps get backing rod first. The sealant then grips the two sides it should. We work on aluminium frames, timber windows & doors and composite doors, and people most often call us about a bead that doesn’t match the frame and gaps left after new windows were fitted.
London has a lot of flats and conversions, where windows are often on upper floors. In a converted house or block, the lease generally says who is responsible for the windows, so it’s worth checking before booking.
All our work comes with our 12-month guarantee, wherever you are in Greater London.

How the visit works
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. It generally takes most of a day for a typical house, less for a few frames. In Hooley, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- We check each frame and agree which ones need doing.
- The old mastic is cut out and the surfaces cleaned back.
- Deep gaps are filled with backing rod to set the depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Finally we tidy up and check each joint.
Getting ready for the visit

What else we do in Hooley
Keeping the joints in good condition
So the new joints stay in good condition:
- Wipe condensation off the frames
- Make sure the drainage slots are not blocked
- Avoid blasting the frames with a pressure washer
- Clean frames with a soft cloth and soapy water
Keep the new mastic undisturbed while it cures, following the cure time we give you. Don’t point a pressure washer at the joints.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. A new joint closes it up.
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. Keeping joints in good order 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.
Window mastic in Hooley: local notes
In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In the older streets around Church of St Margaret, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Letting a property close to Chipstead station? Then renewing tired window mastic between tenants heads off draught and damp complaints. As a London address, Hooley can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

How the job changes by surface
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so we use a flexible, low-modulus sealant. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A neat, narrow bead in a colour to match keeps the clean look.
Honest limits
Some problems need a builder, plumber or other trade rather than us:
- Condensation trapped between the panes
- Draughts through the window seals rather than the frame
- A frame that has rotted at the joint
Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly.

Can I do it myself?
If you’ve already had a go yourself, that is fine. We cut it out and start again.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Questions from Hooley
Is parking an issue for window mastic in Hooley?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
I let a flat near Chipstead station. Can you help?
Yes, we work for landlords and agents. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear quote.
Will it make a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Can new window sealant be painted?
Silicone generally won’t take paint. Let us know beforehand, and we will use a paintable product where it suits.
Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Can you get sealant to suit coloured frames?
Yes, we choose a colour to suit the frame. Anthracite grey, black, brown and white cover most frames, with clear as an option.
Can you do several jobs on one visit?
Yes. More than one area can be quoted together.
Do you seal inside as well as outside?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We do one or both.
Leave it or put it right?
Not every sealant suits a window. Interior caulk and bathroom silicone aren’t made for exterior frame joints. An exterior, low-modulus sealant stays flexible in sun and frost. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Hooley, the repair is bigger than a sealant job.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.
