Windows and doors in Charney Bassett
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. Historic houses like Longworth House (about 2.9 miles north) are a reminder that the area around Charney Bassett 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.
Around Charney Bassett, as everywhere, window mastic is only as good as the preparation behind it.

Leave it or put it right?
A quick bead over the top of old mastic looks like an easy fix, but new sealant can’t bond to old, crumbling mastic. It soon lifts and the leak carries on behind it. The old mastic has to come out. Older cottages and farmhouses around Charney Bassett can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Doing several joints on one visit generally makes better use of the time than several visits. You will get one clear quote for the whole job.

What the job involves on each surface
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We can talk through the options.
Composite doors
Composite doors are normally hung in an uPVC-type frame, so its perimeter joint is sealed much like a window. The bead is colour-matched to the frame.
Common problems we fix in Charney Bassett
Frames are never completely still. Sun on a frame makes it expand, and it contracts again overnight, while the masonry beside it stays put. If the sealant cannot stretch, it splits.
The problems people generally mention when they call include:
- A bead that doesn’t match the frame
- Old mastic that has gone black or come away
- Rain getting in at the frame or under the sill
- Cracked or shrunken mastic around the frame
Homes close to Church of St Peter include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in.
Questions to ask before booking
- Whether VAT is included
- Are they insured?

Common questions in Charney Bassett
What guarantee comes with window mastic in Charney Bassett?
Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Do you cover Charney Bassett for window mastic?
Yes. We work across London and the South East, and Charney Bassett is part of that. You can phone 0345 464 0079 or send us an email and tell us what needs doing.
When is the sealant fully cured?
It depends on the product. We tell you how long to leave it before we go.
How much does window mastic cost in Charney Bassett?
It depends on the job, so we quote each one individually. For a quick quote, call 0345 464 0079 or send us an email with a short description of the job.
Do you seal inside as well as outside?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We can do either or both.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access.
Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little.
Can you reach windows above the ground floor?
Yes, if safe access is possible. For high or awkward windows, we’ll tell you what access is needed.
Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Wipe condensation off the frames
- Wash the frames with mild soapy water
- Check the mastic once a year
- Avoid harsh chemicals near the mastic
Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just phone 0345 464 0079 or email us.
Wet, windy weather is when failed mastic shows itself, but resealing works best in dry conditions. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.

The process
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it usually takes most of a day for a typical house, less for a few frames. For a village or hamlet like Charney Bassett, the journey is planned in advance: 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.
- Old, cracked mastic is removed completely.
- The surfaces are cleaned and left dry.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Before we arrive
- Clear items away from the joints we’re working on
- Mention if the joints have been sealed before
- Let us know about parking restrictions
