- Damp patches on the reveal after heavy rain
- Untidy mastic left by window fitters
Window mastic in West Kingsdown, done properly
Colour matters on a frame. White, brown, anthracite grey, black and clear sealants are all available, so the bead blends with the window rather than framing it. We work on timber windows & doors, aluminium frames and window sills, and people most often call us about untidy mastic left by window fitters and damp patches on the reveal after heavy rain.
In smaller places like West Kingsdown, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. The right sealant depends on the frame and on what it sits in.
Each job carries a 12-month guarantee, whatever its size.

How we quote for window mastic
We quote each job individually. This is what makes a difference:
- Whether the work is at height
- The type of sealant required
- The size of the job
- How many areas need sealing
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
Asking for a quote
Before you ask for a quote, have a think about:
- Any previous sealing or DIY work
- A few photos by email, if you can
- What’s wrong with the joints now
- Where the property is
Getting a quote is simple: let us know the job and the location, and roughly how big it is. A few pictures by email make the job easier to understand.
When something else is needed
In fairness, some problems need a different trade:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Faulty window hardware
- Soft or decayed wood in the frame
If you’re not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer.

West Kingsdown: your questions answered
Can you do window mastic in West Kingsdown?
Yes, West Kingsdown is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or email us and let us know what needs doing, and we will give you a clear price.
Do you cover smaller places like West Kingsdown?
Yes, West Kingsdown is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We will give you the cure time for the product we used.
I’m a tenant. Can you help?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Will you leave a mess?
We keep the work tidy. We protect what’s around the joints.
Can you seal over the old sealant?
No, it won’t last. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Can I do it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Will new mastic stop draughts?
Often, yes. Air often gets in between the frame and the wall, and sealing the inside and outside joints closes that path.
What we’re called out for in West Kingsdown
Sun, frost and rain wear sealant out. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.
Signs it’s time to call us include:
- Hard, cracked sealant around windows
- Untidy mastic left by window fitters
- Leaking joints at the ends of sills
- Cracked internal joints between frame and plaster
For landlords with property near Eynsford station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Landlords, agents and businesses in West Kingsdown
Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
What happens on the day
There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The work itself takes a few hours for a few frames, or a day or more for a whole house, including the tidy-up. A visit to West Kingsdown is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We check how each frame can be reached safely.
- All the failed sealant is cut away, along with any loose debris.
- 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.
How to prepare
- Mention any leaks or damp you’ve noticed
- For business premises, tell us about site rules or sign-in
- For indoor joints, keep the area dry beforehand if you can

West Kingsdown homes and the weather
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Lullingstone Castle (about 2.8 miles west) are a reminder that the area around West Kingsdown 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.
For an older house near a landmark such as Church of Saint Edmund, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Schools such as West Kingsdown CofE VC Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

Why act early in West Kingsdown
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. Homes in smaller places like West Kingsdown can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Doing several joints on one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will give you a clear price for the lot.
