Expansion joint sealing in Lagness, done properly
Long runs of brick or block have movement joints built in that most people only notice when the sealant has gone. Once the seal fails, rain reaches the cavity and the joint can no longer close. The old seal comes out, backing goes in and a sealant with the right movement class is applied with primer where the maker calls for it. If you have weathered movement joint sealant that no longer flexes and damp inside where a wall movement joint has failed, we can help. Whether you call it commercial sealant work, mastic application or joint sealing, in Lagness it comes down to the same thing: the right product in a properly prepared joint.
Jobs around smaller places like Lagness are planned so the whole job is done in one visit, with the right materials on hand. Tell us the joint widths if you can, and what drives or walks over them.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Traffic, movement and joints around Lagness
Lagness is within about 2 miles of the coast. External movement joints in car parks, ramps and yards near the coast take salt and wind-driven rain on top of traffic, which is why split joints are worth sealing before the edges deteriorate. Lagness is about 56 miles from central London. The roads out of London are lined with trade parks and distribution sheds.
If you manage units on an estate such as Quarry Lane Industrial Estate, which lies north-west of Lagness, the floor joints under forklifts and pallet trucks and the slab joints in the yard are the ones to watch. For estates staff at a university like University of Chichester (1.3 miles north of Lagness), building and paving joints are part of the planned maintenance list.

When to bring in a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
Different surfaces, different methods
Podium joints
Podiums take foot traffic, planters and weather. We choose a product that copes with feet, wheels and weather.
Brickwork and blockwork joints
Long brick and block elevations have movement joints at intervals. We use a sealant rated for the movement, normally low-modulus laid over backing rod at the correct depth.

What else we do in Lagness
When to call us in Lagness
With no backing rod or bond-breaker in place, sealant grips the base of the joint too. Sealant fixed to the base and sides can’t flex, so it tears.
Look out for the following:
- Sealant pulling off the joint face
- Water dripping through deck or ramp joints
- Damp inside where a wall movement joint has failed
- Spalled or broken joint edges in floors and decks
At a retail site such as Arun Retail Park, 2.7 miles to the east of Lagness, trolleys, cages and cars run over floor and slab joints all day.

On site: what to expect
Working in a building that stays open takes some planning. We sign and contain the area we’re in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Rural sites near Lagness may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.
- The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
- A fixed quote follows, naming the sealant and its movement class.
- Old sealant and filler are cut out and the joint faces cleaned back to sound material.
- We control the depth with backing rod or, in shallow joints, bond-breaker tape.
- Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
- Each joint is inspected and handed over with our 12-month guarantee.
Before we start on site
- Agree which areas must stay open
- Confirm the product named in the specification
- Make sure the joints can be reached

Questions about Lagness
Can you work at a site such as Quarry Lane Industrial Estate, by Lagness?
Yes. Estates, retail parks and business parks around Lagness, Quarry Lane Industrial Estate among them, are all within reach. To start, just speak to us on 01277 525 020 or email us with the unit, the joints involved and your access times.
Is a smaller place like Lagness outside your area?
Not at all. Lagness is within our area. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
What will the job cost?
There isn’t a price list, as every site differs. Send photographs or drawings and we will price it at a fixed figure.
What causes movement joint sealant to fail?
It depends on how the sealant has let go: a split through the middle points to over-stretching, while peeling from one face points to preparation or primer. Broken edges are a third possibility.
Can weather delay the job?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Are you CHAS accredited?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
Will your applicators have CSCS cards?
Yes. If you need card details for site access, let us know and we will send them with the quote.
Aftercare for building managers
Your facilities or cleaning team can help the joints last. Share these points with them:
- Keep traffic off new joints until the cure time is up
- Avoid parking heavy plant or pallets on joint lines
- Put movement joints on the planned maintenance inspection round
- Look over external and deck joints after a hard winter
Keep wheels, feet and water off new joints until the sealant has cured. How long that takes depends on the product, the temperature and the depth of the joint, and we confirm it for each area before we leave. Barriers left in place until then protect the finish.
Joints sealed at the same time generally fail around the same time. It pays to check every joint, not just the obvious one so you can prioritise and budget. We will tell you which movement joints need doing now and which can wait.
