About our window mastic in Kilndown
From a single sill to a whole house of windows, the work is priced before anything is done. To get one, ring 0345 464 0079 or email us with the number of frames and any access details. If you have old mastic that has gone black or come away and whistling draughts around closed windows, we can help, whatever the surface.
Around Kilndown, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
A 12-month guarantee comes as standard.

Kilndown: your questions answered
What guarantee comes with window mastic in Kilndown?
Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Do you cover smaller places like Kilndown?
Yes, Kilndown is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Is it OK to seal over old sealant?
No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
Can landlords and businesses book you?
Yes, regularly. We can quote for several properties at once, and between tenancies is a good time for the work.
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.
Do you have sealant for grey or black windows?
Yes. We can use white, brown, anthracite grey, black or clear, so the joint suits the frame.
I rent my home. Can I book you?
We can work for tenants, landlords or agents. Just make sure your landlord agrees.

How the job changes by surface
Window sills
Sills catch the water running down the glass, so the joints at each end and underneath matter. Each is cleaned out and resealed.
Composite doors
Draughts round the door leaf normally come from worn seals or adjustment, not the mastic. We will tell you if that’s what we find.
What we do, step by step
We keep the work tidy and contained to the area we are working on, so you can get on with your day. The job usually takes a few hours for a few frames, or a day or more for a whole house, and we explain the cure time before we leave. Somewhere as small as Kilndown, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we look at every frame and agree the list.
- Next the failed sealant is cut away and the joint cleaned.
- Where gaps are deep, backing rod goes in first.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Finally we tidy up and check each joint.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Keep children and pets away from the work area
- For indoor joints, keep the area dry beforehand if you can
Getting a quote
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email photos if that is easy.
Advice
When to call us in Kilndown
Timber windows bring their own problems. Old mastic gets painted over and cracks under the paint, and the wood moves with damp as well as heat.
Most people get in touch after spotting one of these:
- White mastic on grey or black frames
- Black, perished sealant on frames
- Cracked sealant at the sill ends
- Gaps left after new windows were fitted
In and around Kilndown, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.
Questions to ask before booking
- How much experience the applicator has
- When the joint can take water or movement
- What product goes in the joint
- Whether VAT is included
When something else is needed
We will not take on work that will not last, so these are the limits:
- Draughts through the window seals rather than the frame
- Damp coming through the wall itself rather than the frame joint
- Rotten timber, which needs a joiner first
If you’re not sure, just call 0345 464 0079 or email us and we will give you a straight answer before booking.
Joints and surfaces we work on
- Patio & French doors
- Composite doors
- Timber windows & doors
- Window sills
- Aluminium frames
- uPVC windows
Leave it or put it right?
Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished, and it’s easier while the walls are being worked on anyway. Older cottages and farmhouses around Kilndown can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and send you a clear quote before any work starts.
Why us?
- Approved under the ARBOMaster scheme
- White, clear, grey or coloured to suit, where the product allows
- Old sealant always removed completely
- Homes, businesses and hotels

Frames and glazing around Kilndown
Historic houses like Scotney Castle (about 0.8 miles west) are a reminder that the area around Kilndown has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. 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.
In the older streets around Christ Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
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.
Aftercare tips
A little care helps the new joints last. We recommend:
- Keep paint and stain on wooden frames in good order
- Air rooms to keep condensation down around windows
- Don’t aim a pressure washer at the joints
- Keep paint off silicone joints
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak, and if anything looks wrong, just call 0345 464 0079 or drop us an email.
Leaks normally show up in wet, windy weather, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.
