Window mastic for homes and businesses in Hythe
The new joint doesn’t have to be white. 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 aluminium frames, window sills and patio & French doors, and common reasons people get in touch are cracked or shrunken mastic around the frame and mastic that’s falling out in pieces.
Walls in Hythe that face the prevailing wind take the most weather, so the mastic there tends to fail first. It’s worth looking at every frame, not just the one that leaks.
Whatever the size of the job, it’s backed by our one-year guarantee.

When it isn’t the sealant
Some problems need a builder, plumber or other trade rather than us:
- Broken hinges, locks or handles
- Worn gaskets, brush seals or a door that has dropped
- Damp problems in the wall away from the window
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think.
Joints and surfaces we work on

Can I do it myself?
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.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
Landlord and commercial work in Hythe
Housing providers, facilities teams and property managers book us too in Hythe and across Kent. We can quote a run of properties together, and we’re fully insured for the work.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
Aftercare tips
So the new joints stay in good condition:
- Use gentle cleaners on frames and sealant
- Do not use solvent cleaners on the joint
- Repaint timber before it’s bare
- Paint up to the joint, not over it
Silicone can’t normally be painted, so mention any painting plans before any work starts. There are paintable sealants for joints that need it.
A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.
What else we do in Hythe
Questions from Hythe
Can you do window mastic in Hythe?
Yes, Hythe is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or drop us an email and let us know what needs doing.
I let a flat near Sandling station. Can you help?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used before we leave.
Can resealing stop a draught around my window?
Yes, if the air is getting in around the frame. If it’s through the window’s own seals or a hinge, that is a different fix, and we will say so.
How much does window mastic cost in Hythe?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Can you get sealant to suit coloured frames?
Yes. White, brown, anthracite grey, black and clear sealants are all available, so the joint suits the frame.
Can you do upstairs windows?
Usually, yes. We plan safe access before the job.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is usually more efficient.
Frames and glazing around Hythe
Hythe is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. 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.
For an older house near a landmark such as Church of St Michael and All Angels, the joint between an old wall and a newer frame is usually the first place rain gets in. Managing a site like Hythe Bay CofE Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. For landlords with property near Sandling station, renewing tired window mastic between tenants heads off draught and damp complaints.

What happens on the day
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself normally takes a few hours for a handful of frames, longer for a whole house, depending on the size of the job. Parking in a town like Hythe is generally straightforward, but tell us if there’s a driveway or any restrictions, and mention if the work is upstairs, in a flat or high on the outside.
- We check how each frame can be reached safely.
- All the failed sealant is cut away.
- The surfaces are cleaned and left dry, 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.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- Plan for the work area to be out of bounds to pets and children
- On commercial sites, let us know about site rules

Advice
Why deal with it now?
Working on frames from a ladder with a sealant gun is not easy, especially upstairs. A professional job is cut out properly, backed where needed and finished neatly, using a product chosen for the frame and wall. Draughts from a gap round a frame, damp under a sill or water behind a bath panel all start small, and early is when they’re cheapest and quickest to sort.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote.
