About our window mastic in West Hythe
Colour matters on a frame. We can seal in white, brown, anthracite grey, black or clear, so the bead blends with the window rather than framing it. We work on timber windows & doors, composite doors and patio & French doors, and people most often call us about gaps where the sill meets the wall and mastic that has split away from the wall.
Homes in small places like West Hythe often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
We stand behind the work with a one-year guarantee.

Can I do it myself?
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 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.

What we do, step by step
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes most of a day for a typical house, less for a few frames. For a village or hamlet like West Hythe, 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.
- Old, cracked mastic is removed completely, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Move anything stored near the joints
- For indoor joints, keep the area dry beforehand if you can

Advice
Your questions about window mastic in West Hythe
Is West Hythe within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you work for landlords with property near Westenhanger station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
What does window mastic cost?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before work begins.
Can you seal over the old sealant?
No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Can you match the sealant to my frames?
Yes. Grey and black frames get grey or black sealant, and wood-effect frames normally suit brown.
Which products do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll explain our choice.
Where are you based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Can I add another job to the visit?
Of course. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.

- A sash or casement that won’t close properly
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly before you book.

Frames and glazing around West Hythe
West Hythe is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around window and door frames, especially on the side facing the sea. Historic houses like Westenhanger Castle (about 1.8 miles north) are a reminder that the area around West Hythe 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.
If you look after a building such as Lympne Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages. For landlords with property near Westenhanger station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Common problems we fix in West Hythe
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.
Signs it’s time to call us include:
- Old mastic that has gone black or come away
- Untidy mastic left by window fitters
- Gaps where the sill meets the wall
- Draughts coming in around windows and doors
If you live in an older home near Church of St Stephen, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

How to look after the new joints
So the new joints stay in good condition:
- Keep timber frames painted
- Check the mastic once a year
- Keep drainage slots and sill grooves clear
- Wash the frames with mild soapy water
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak.
Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
Why deal with it now?
Resealing frames is a short job: the visit takes anything from an hour or two to a full day, depending on how many frames there are. Wait for damp to appear and there may be plaster and decorating to sort out too. In a small place like West Hythe, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, phone 0345 464 0079 or drop us an email for an honest opinion and a quote.
