How we handle window mastic in Norwood New Town
Most frames have an outside joint and an inside one. The external joint is the weather seal; inside, the joint between frame and plaster stops draughts and tidies the reveal. Either or both can be done. We work on timber windows & doors, composite doors and aluminium frames, and the jobs we see most are white mastic on grey or black frames and mastic that’s falling out in pieces.
Many London homes are flats, with windows high above the street. In a converted house or block, the lease generally says who is responsible for the windows, so it’s worth checking before booking, and access in Norwood New Town is something to talk through when you book.
All of our work is guaranteed for twelve months.

Different surfaces, different methods
Patio & French doors
Door frames take knocks and movement every time the doors are used. The sealant must cope with it, where a rigid one would crack.
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. We cut it out, back any deep gaps and reseal properly.

What we are called out for in Norwood New Town
A lot of older mastic was never designed to stay flexible. Once it has hardened, the frame’s movement tears it from the wall, leaving a hairline gap down one side.
Most people get in touch when they notice one of these:
- Draughty joints inside around the window
- Mastic that has split away from the wall
- Damp patches on the reveal after heavy rain
- Leaking joints at the ends of sills
For site and facilities teams at buildings such as Rockmount Primary School, its window and door frames need their mastic kept sound, just like a home’s.

How the visit works
Every visit runs the same way: we check the joints, protect the area around them, carry out the job and clear up. It generally takes most of a day for a typical house, less for a few frames. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Tell us if parking is tricky

Advice
Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Check the mastic once a year
- Repaint timber before it’s bare
- Wash the frames with mild soapy water
- Keep drainage slots and sill grooves clear
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 resealing works best in dry conditions. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
