Frames and glazing around Ditton Hill
In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking. Historic houses like Hampton Court Palace (about 2 miles north-west) are a reminder that the area around Ditton Hill 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.
Ditton Hill is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. Homes close to Church of St Mary include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Window mastic in Ditton Hill
From a single sill to a whole house of windows, the work is priced before anything is done. Just phone 0345 464 0079 or send us an email and tell us how many frames there are and how they’re reached. Common call-outs are for rain getting in at the frame or under the sill and mastic that has split away from the wall, across uPVC windows, patio & French doors and window sills.
London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. The mastic around them dries out and cracks with age, letting in draughts and water.
Big or small, you get the same one-year guarantee in Ditton Hill and across Greater London.

- Broken hinges, locks or handles

How the job changes by surface
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. We cut it out, back any deep gaps and reseal properly.
Timber windows & doors
Wood swells when it’s wet and shrinks when it dries, so a flexible sealant is essential. The paint or stain needs to be sound where the sealant meets it.
What we do, step by step
There is not much for you to do on the day. Show us the job and we will take it from there. The job generally takes anything from an hour or two to a full day, depending on how many frames there are from start to finish. 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 look at every frame and agree the list.
- We remove the old mastic and clean the frame and the wall.
- Where gaps are deep, backing rod goes in first.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- For business premises, tell us about site rules or sign-in
- Clear the area around the work

Common problems we fix in Ditton Hill
Timber windows bring their own problems. Old mastic gets painted over and cracks under the paint, and timber moves with moisture as well as temperature.
It’s worth asking for a quote if you see:
- Untidy mastic left by window fitters
- Leaking joints at the ends of sills
- Damp patches on the reveal after heavy rain
- Black, perished sealant on frames
Schools such as Long Ditton Infant and Nursery School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
Questions to ask before booking
- What happens if they find a problem under the old sealant
- How the surfaces are prepared before sealing
- When the joint can take water or movement
- How the colour is chosen
DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
