Window mastic in Bailey Green, done properly
Every window and door frame has a gap around it, and mastic is what closes it. Once that seal fails, wind and rain find the gap. Our applicators cut it out and replace it with a flexible, weatherproof sealant. Common call-outs are for mastic that’s falling out in pieces and leaking joints at the ends of sills, on aluminium frames, window sills and timber windows & doors.
Somewhere as small as Bailey Green, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
We stand behind the work with a one-year guarantee.

DIY sealant or a professional job?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Common problems we fix in Bailey Green
A lot of older mastic was never designed to stay flexible. Once it has hardened, the frame’s movement tears it from the wall, and a gap opens along one edge.
The most common problems we see are:
- Cracked sealant at the sill ends
- Whistling draughts around closed windows
- Damp patches on the reveal after heavy rain
- Gaps left after new windows were fitted
In and around Bailey Green, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.
Questions to ask before you book
- How much experience the applicator has
- Is VAT in the price?
- What happens if they find a problem under the old sealant
- Which sealant they’ll use, and why
For landlords and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
If you manage several properties in or around Bailey Green, several properties can be quoted together. Just tell us the addresses and what each one needs, and pictures by email help.
Frames and glazing around Bailey Green
Historic houses like Hinton Ampner House (about 4.7 miles west) are a reminder that the area around Bailey Green 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. 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.
Homes close to Holy Trinity Church include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in.

Different surfaces, different methods
Patio & French doors
Heavy door frames can move more than windows. A flexible sealant copes with that without cracking.
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.
How to look after the new joints
So the new joints stay in good condition:
- Ventilate rooms so frames don’t stay wet inside
- Walk round the house once a year and look at the joints
- Avoid blasting the frames with a pressure washer
- Do not paint over the silicone
Silicone can’t normally be painted, so mention any painting plans before work begins. We can use a paintable sealant where that matters.
Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so early resealing is worth it.
Your questions about window mastic in Bailey Green
What guarantee comes with window mastic in Bailey Green?
All our work, in Bailey Green and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Is Bailey Green in your area for window mastic?
Yes. We work across London and the South East, and Bailey Green is part of that. You can ring 0345 464 0079 or drop us an email and tell us what needs doing, and we will send you a clear quote.
Will the old sealant be removed?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
How many windows can you do in a day?
A handful of frames is a short visit, while a whole house takes longer. We confirm the timing with your quote.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints.
Can you do several jobs on one visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Are you fully insured?
Yes. Full insurance covers our work.
Do you seal inside as well as outside?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We can do either or both.
How the visit works
There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the work takes anything from an hour or two to a full day, depending on how many frames there are in most cases. For a village or hamlet like Bailey Green, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away, along with any loose debris.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Clear items away from the joints we are working on
- For indoor joints, keep the area dry beforehand if you can
