Window mastic in Whyteleafe, done properly
Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that cannot flex, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. If you have black, perished sealant on frames and draughty joints inside around the window, we can put it right, whatever the surface.
Homes in small places like Whyteleafe often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
There’s a 12-month guarantee on every job.

What window mastic looks like in Whyteleafe
Historic houses like Addington Palace (about 3.9 miles north-east) are a reminder that the area around Whyteleafe has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Schools such as Whyteleafe Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. Rented homes near Upper Warlingham station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. For an older house near a landmark such as St Luke, the joint between an old wall and a newer frame is generally the first place rain gets in.

How the visit works
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a morning for a couple of windows and a door.

Everything for the job comes with us, so a second trip is avoided where possible.
- We start by checking each window and door with you.
- Next the failed sealant is cut away and the joint cleaned.
- Deep gaps are filled with backing rod to set the depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Finally we tidy up and check each joint.

How the job changes by surface
Patio & French doors
Door frames take knocks and movement every time the doors are used. A flexible sealant copes with that without cracking.
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the bottom joint sees the most water. We prepare and reseal every joint, backing the deep ones.
DIY versus a professional finish
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Air rooms to keep condensation down around windows
- Do not paint over the silicone
- Keep drainage slots and sill grooves clear
- Keep solvents and bleach off the sealant
Wipe the frames with soapy water when you clean the windows, and keep solvents and harsh chemicals off the joint.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.
