Window & door mastic in West Farleigh, Kent
Window mastic across West Farleigh and nearby, with every bit of old sealant taken out first and a 12-month guarantee.
- Whistling draughts around closed windows
- Gaps between the frame and the inside reveal
- Mastic that has split away from the wall
How we handle window mastic in West Farleigh
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. That way the new bead bonds to the frame and the wall only. If you’re dealing with sealant in the wrong colour for the frame and gaps where the sill meets the wall, we can help, whatever the surface.
Mastic can only go onto a dry, clean joint, so window work in West Farleigh is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
We stand behind the work with a 12-month guarantee, so you’re covered after we have gone.

The process
We keep the work tidy and contained to the joints we are treating, so you can carry on as normal. Expect the work to take a morning for a couple of windows and a door. Somewhere as small as West Farleigh, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check each frame and agree which ones need doing.
- We remove the old mastic and clean the frame and the wall.
- Deep gaps are filled with backing rod to set the depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- We clear up and check every joint is fully closed.
Getting ready for the visit
- Mention any parking rules near the property
- Clear the area around the work
- Mention any leaks or damp you’ve noticed

Should I try it myself first?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
Questions from West Farleigh
Do you cover smaller places like West Farleigh?
Yes. West Farleigh is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you do window mastic in West Farleigh?
Yes. We work across London and the South East, and West Farleigh is part of that. You can ring 0345 464 0079 or email us and let us know what needs doing, and we will give you a clear price.
Are you ARBOMaster approved?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
What information do you need?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
Do you take out the old sealant first?
Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
How long will my window job take?
A handful of frames is a short visit. You’ll get a timescale with the quote.
Can you reach windows above the ground floor?
Yes, where it’s safe. Higher or awkward frames may need extra access, and we will confirm what’s needed.
When it is not the sealant
A few problems are outside what sealant work can do:
- Draughts through the window seals rather than the frame
- A frame that has rotted at the joint
- A sash or casement that won’t close properly
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think before you book.
What we seal
- Timber windows & doors
- uPVC windows
- Composite doors
- Window sills
- Patio & French doors
- Aluminium frames
What happens if it’s left?
Once mastic fails, rain can get between the frame and the wall. Over time that can mean damp patches, damaged plaster and rotting timber. A reseal is a much smaller job. Where a wall is exposed, as many are in small places like West Farleigh, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first.

Surface by surface
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the bottom joint sees the most water. We prepare and reseal every joint, backing the deep ones.
Composite doors
Front doors take the weather head on. Those corners get the most care.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Keep timber frames painted
- Air rooms to keep condensation down around windows
- Avoid blasting the frames with a pressure washer
- Wash the frames with mild soapy water
On timber frames, keep the paintwork in good order, because bare, wet timber moves more and pulls at the joint. Keep paint off the silicone itself.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and heat escapes around the frame. A new joint closes it up.

Do you need window mastic in West Farleigh?
Joints that are too thin or too deep fail early. A skim of sealant over a wide gap soon tears, while a joint packed solid can’t stretch. Backing rod sets the right depth.
Most people get in touch after spotting something like this:
- Draughty joints inside around the window
- Mastic that’s falling out in pieces
- Untidy mastic left by window fitters
- White mastic on grey or black frames
If you live in an older home near All Saints Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
