What we do, step by step
When we arrive, we look over the joints with you first, so you know exactly what we are doing. Surfaces next to the work are protected before any work begins. The work generally takes anything from an hour or two to a full day, depending on how many frames there are. Somewhere like Asheridge needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away.
- Frame and wall are cleaned and must be dry before sealing.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Clear the area around the work
- Keep pets and children clear of the area while we work

Advice
What happens if it’s left?
Running fresh sealant over the old joint is tempting, but it will not grip old, dirty sealant. It peels before long, and water still gets in behind. Proper resealing starts with removing the old joint. Around Asheridge, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we’ll go through it with you.
Why book with us
- 4.9 on Google from 180+ five-star reviews
- White, clear, grey or coloured to suit, where the product allows
- Quality sealants from Arbo and Everbuild
- Neat joints and a tidy finish
Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Keep solvents and bleach off the sealant
- Clean frames with a soft cloth and soapy water
- Do not paint over the silicone
- Ventilate rooms so frames don’t stay wet inside
Keep the new mastic undisturbed while it cures, following the cure time we give you. Keep jet washers away from the frames.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. Resealing closes it.
Asheridge homes and the weather
Historic houses like Cholesbury Manor House (about 1.7 miles north) are a reminder that the area around Asheridge 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. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you let a flat or house near Great Missenden station, renewing tired window mastic between tenants heads off draught and damp complaints. In the older streets around St John's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you look after a building such as Chartridge Combined School, the mastic around its windows and doors needs looking after like any other building’s.

For landlords and businesses
Landlords and letting agents in Asheridge can book us as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.

How the job changes by surface
uPVC windows
We clean the frame edge carefully so the plastic isn’t marked, then the new bead is laid against the frame and the wall and tooled smooth.
Patio & French doors
Door frames take knocks and movement every time the doors are used. A flexible sealant copes with that.
When it is not the sealant
New sealant can’t fix everything, and we’d rather say so up front. Sealant will not put right:
- Penetrating damp from a failed cavity tray or render
- Faulty window hardware
- Soft or decayed wood in the frame
If you’re not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer.
