Different surfaces, different methods
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. The movement joint takes that up, so its sealant has to stay flexible.
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.
External mastic in Lawford, done properly
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall so the line blends in. If you have brick movement joints where the sealant has split and weeds or debris growing in open joints, we can help, on brickwork movement joints, render & cladding joints and concrete & block alike.
In and around Lawford, older properties sit alongside newer ones, each with its own outside joints. Older homes need their gutter and trim joints kept tight, newer ones their movement joints.
We stand behind the work with a one-year guarantee.

What affects the cost of external mastic
For a quick quote, just ask. What matters most is:
- Access and height
- Whether there’s mould to deal with
- How many areas need sealing
- Working hours on commercial sites
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we’ll explain what it covers.
What we need to know
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- How we’d reach the joints
- Roughly how big the job is
- The problem you’ve noticed
- A few photos by email, if you can
For a quote, phone 0345 464 0079 or send us an email with the location and a short description of the problem. You’ll have a clear quote before work begins.
Honest limits
Some problems need a builder, plumber or other trade rather than us:
- Structural movement, which needs a surveyor or engineer
- Damp that is not coming from the joint
- Cracking across the wall rather than at a joint
If you’re not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer.
What we seal

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
What we do, step by step
The work is kept neat and contained to the joints we’re treating, so you can get on with your day. The job usually takes a few hours to a few days, depending on the length of joint and the access, and we tell you how long to leave it before we go. A visit to Lawford is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Mention any tricky access
- Keep children and pets away from the work area

Lawford: your questions answered
Will you come out to Lawford?
Yes, Lawford is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you work for landlords with property near Manningtree station?
Yes. We work for landlords and agents as well as householders, and several properties can go on one quote. You can phone 0345 464 0079 or email us with the details for a clear quote.
What sealant do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status.
Can I add another job to the visit?
Yes. Just list everything you need and we will quote it together.
Can you match the colour of my brickwork?
The sealant colour is picked to suit the wall, so the joint sits quietly in the wall. There’s a wide choice of exterior colours.
When will the joints need doing again?
It varies from wall to wall: joints on exposed walls or with a lot of movement age sooner. A yearly look will tell you when they need doing. Every job carries our one-year guarantee.
Will there be a smell?
Some sealants have a smell while they cure. Ventilation helps.
External mastic in Lawford: local notes
Lawford is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Rented homes near Manningtree station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets. Schools such as Manningtree High School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For an older house near a landmark such as St Mary's Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Why it’s worth doing now in Lawford
A properly done movement joint is an even line in a colour that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner, so it pays to do it properly once. Around Lawford, 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.
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. The price is agreed before we begin.
