Window Mastic in Dymchurch
Problem with your window and door frames in Dymchurch? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.

- Rain getting in at the frame or under the sill
About our window mastic in Dymchurch
The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. If you are dealing with cold air getting in at the frame edge and untidy mastic left by window fitters, we can help, whatever the surface.
Many houses in smaller places like Dymchurch have conservatories, garden rooms or patio doors. Their glazing joints and frame seals are as much a part of the job as the windows, and any older timber or sash windows need a sealant that suits them.
We stand behind the work with a one-year guarantee, so you’re covered after we’ve gone.

We do not publish a price list, because no two jobs are the same. What we look at:
- Whether old sealant or filler has to be cut out
- Any mould that needs treating
- Any working-time requirements on site
- The amount of work
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

Photos by email are helpful but not essential. Please mention:
- What the problem is, such as mould, gaps, leaks or cracking

How it works
We bring everything the job needs with us. Once we’ve agreed what’s being done, we protect the area and start. It normally takes a few hours for a handful of frames, longer for a whole house. In a smaller place like Dymchurch, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We start by checking each window and door with you.
- We remove the old mastic and clean the frame and the wall.
- Where gaps are deep, backing rod goes in first.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- We clear up and check every joint is fully closed.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Let us know about earlier repairs to the joints
- Tell us about access, such as stairs, a lift or high-level joints

Questions from Dymchurch
I let a flat near Westenhanger station. Can you help?
Yes, we work for letting agents and landlords. You can call 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before we start.
Does the coastal weather in Dymchurch affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Can resealing stop a draught around my window?
Often, yes. Air often gets in between the frame and the wall, and sealing the inside and outside joints closes that path.
Is it OK to seal over old sealant?
No, it won’t last. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
How long does it take to reseal the windows on a house?
Allow a few hours for a handful of frames, longer for a whole house. Access and how stubborn the old mastic is affect the time most.
What do you put in the joint?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
How long should I leave it?
It depends on the product and the conditions. Before we leave, we will tell you the cure time.
Is there any odour?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
What happens if it’s left?
A quick bead over the top of old mastic looks like an easy fix, but it won’t grip old, dirty sealant. It peels before long, and water still gets in behind. The old mastic has to come out. Around Dymchurch, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.

What the job involves on each surface
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A tidy bead in anthracite grey, black or a matching colour suits the frame.
Window sills
Stone and concrete sills have their own joints, and the joint under the frame can let rain run behind. Those are sealed with a product suited to stone or concrete.
Common problems we fix in Dymchurch
Older frames were often sealed with products that set hard. Once it has hardened, the frame’s movement tears it from the wall, leaving a hairline gap down one side.
Keep an eye out for any of the following:
- Gaps where the sill meets the wall
- Hard, cracked sealant around windows
- Old mastic that has gone black or come away
- Damp patches on the reveal after heavy rain
Rented homes near Westenhanger station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Dymchurch homes and the weather
Dymchurch is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. With historic houses such as Westenhanger Castle (about 4.5 miles north) nearby, there’s older building stock in the area around Dymchurch as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
In the older streets around Church of St Peter and St Paul, frames set in older brick or stone need a sealant that suits the wall as well as the frame. If you look after a building such as Dymchurch Primary School, the mastic around its windows and doors needs looking after like any other building’s.
