Questions from Dymchurch
Does the coastal weather in Dymchurch affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are usually the first to need attention.
Do you work for landlords with property near Westenhanger station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before work begins.
Do you come to Dymchurch?
Yes. We work in Dymchurch and the rest of Kent, as part of our work across South East England, London and Scotland. To book, phone 0345 464 0079 or send us an email.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
How long will you be here?
Most jobs take anything from a few hours to several days, depending on the building, including preparation and clearing up. Your quote will say how long we expect yours to take.
Can you reach joints on upper floors?
It depends on the building. Tell us the height, the number of joints and what’s below them and we’ll confirm how they can be reached safely.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
External mastic in Dymchurch, done properly
Movement joints let brickwork, render and cladding expand and shrink without cracking. Its sealant has to flex with the building, season after season, and when it fails, the wall takes the strain and water finds a way in. If you are dealing with joints with sealant missing in places and hard, crazed mastic that has stopped moving, we can help.
In a smaller place like Dymchurch, some homes face open ground, and walls and rooflines facing the weather take the worst of it. That is where gutter joints and wall joints tend to fail first.
All our work is covered by our one-year guarantee, wherever you are in Kent.

How to look after the new joints
A little care helps the new joints last. Our advice:
- Keep high-pressure jets off the joints
- Make sure movement joints aren’t pointed over
- Keep water from gutters off the wall
- Keep soil, plants and ivy away from the joints
Follow the cure time we give you before the joint is knocked or disturbed. Most exterior sealants skin fast but take longer to cure right through.
An open movement joint lets rain into the wall every time it pours. Over time it can mean damp inside, stained render or frost-damaged brick which cost more to put right than the joint.
What we’re called out for in Dymchurch
Weeds, moss and debris in a joint are a sign the sealant has gone. Dirt and roots then trap moisture in the joint.
If you can see any of these, it’s time to have the joints looked at:
- Movement joints with cracked, split or missing sealant
- Rigid filler in a joint that should flex
- Panel joints letting water in
- Joints where the bead has come unstuck
If you look after a building such as Dymchurch Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

How we quote for external mastic
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Which sealant suits the joint
- The old material and how stubborn it is
- How many rooms, windows or areas are involved
- The number and length of the joints
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, call 0345 464 0079 or send us an email for an honest opinion and a quote.
Helping us quote
Photos by email are helpful but not essential. Try to tell us:
- Pictures of the joints, sent by email
- The address or postcode of the job
- What the problem is, such as mould, gaps, leaks or cracking
- Whether it has been sealed before
If you are in Dymchurch and need external mastic, ring 0345 464 0079 or email us. A short description of the job and where it is helps us quote, and you will get a clear quote before any work starts.
For landlords and businesses
We work for landlords and agents as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
The process
Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it normally takes a few hours to a few days, depending on the length of joint and the access. In a smaller place like Dymchurch, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- The old mastic and anything lodged in the joint is removed.
- We clean both faces of the joint and prime them where the product calls for it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Mention any leaks or damp you’ve noticed
- Let us know about parking restrictions
How to get a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.

Surface by surface
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. We size the backing rod to the gap.
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. The movement joint takes that up, so the sealant in it must stay soft and stretchy.

External mastic in Dymchurch: local notes
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. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. 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. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
For an older house near a landmark such as Church of St Peter and St Paul, old and new materials meet at the roofline and walls, which is where sealant earns its keep. For landlords with property near Westenhanger station, outside joints that have cracked can let damp into a rental, so check them between lets.
Dymchurch is about 4 miles south-west of Hythe, in Kent. Homes, rented property, offices and hotels in Dymchurch can book us for external mastic, old or new, large or small.

What’s near Dymchurch
Locally, jobs take us to homes and businesses close to The Ship Inn, among other places. Dymchurch’s nearest station is Westenhanger station, about 4.6 miles north. A little further out are Lympne Castle (2.9 miles north).
Why it’s worth doing now in Dymchurch
Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. In an older home around Dymchurch, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and agree the price before starting.
