Expansion joint sealing in Atherington
Floor movement joints in warehouses, retail and public buildings carry wheeled traffic. Without a sound filler, joint edges chip and spall under load, so the right filler or sealant for the traffic and movement matters. We will tell you if the edges need repairing before sealing. If you are dealing with rain penetration at brick or block movement joints and layers of sealant in a movement joint, we can help, whatever the surface. A specialist sealant contractor works differently from a general builder: on jobs in Atherington, preparation and product choice get the time they need.
For a site near Atherington, measurements and photographs up front mean one trip where possible, with the right materials on hand. Tell us the joint widths if you can, and what drives or walks over them.
Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Diagnose, treat, sign off
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases, and our waste is bagged and taken away as we go. Smaller jobs around Atherington can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.
- The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
- Next, we fix a price and confirm the sealant we propose for the movement.
- Old sealant and filler are cut out and the joint faces cleaned back to sound material, flagging any broken edges that need repair before sealing.
- Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
- Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
- We check every joint before sign-off, and the work carries our 12-month guarantee.
What we need from you
- Clear stock, furniture or equipment away from the joints
- For older buildings, check the asbestos register before work
- Send any specification or drawings in advance

Advice
Surface by surface
Cladding panel joints
Access to cladding joints is agreed before the price is fixed. Photos taken near the joints help us price accurately or a site visit fills the gaps.
Brickwork and blockwork joints
Mortar snots and debris in the joint stop it working. We clear the joint fully before sealing.
Maintenance after handover
A few simple habits keep the new joints working:
- Note which joints were done, when, and with what
- Look over external and deck joints after a hard winter
- Brief car park operatives to protect joint lines during winter clearance
- Reopen bays and walkways only after the stated cure time
Add every elevation, deck and floor joint to your inspection round. Early splits and edges starting to lift show up on a routine check, when they’re still cheap to deal with. Should you spot a problem, you can call the office on 01277 525 020 or use the quote form and send a picture.
Unsupported floor joint edges spall under forklift and pallet-truck wheels. Broken arrises jolt trucks, loads and drivers and the broken length grows with every pass. Keeping the filler or sealant sound protects the floor.
Leave it or put it right?
Leaving a failed movement joint rarely stays a small problem. Grit and water fill the gap and the material either side breaks up and the job grows to repairs as well as sealing. Acting at the first split keeps the cost down. For buildings around smaller places like Atherington, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

Expansion joint sealing around Atherington: points for this area
Atherington sits close to the coast, within about 1 mile. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, and edges left open tend to break up faster. At about 53 miles from central London, Atherington is within reach of the capital. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital.
A healthcare site such as Zachary Merton Hospital, 3.4 miles east of Atherington, depends on car parks, ramps and service yards whose joints take traffic all day. In a school such as St Mary's CofE Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak.

What we’re called out for in Atherington
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, which is why depth control matters.
Things that typically lead to an enquiry:
- Brittle, chalky sealant on external joints
- Sealant peeling off one face of the joint
- Spalled or broken joint edges in floors and decks
- Joints packed with grit and debris
For estates staff at a university like University of Chichester (Bognor Campus), 3.8 miles to the west of Atherington, building and paving joints are part of the planned maintenance list.

Questions about Atherington
Is Rudford Industrial Estate, near Atherington, within your area?
Yes. We cover Atherington and the area around it, including industrial estates, business parks and retail parks such as Rudford Industrial Estate. Photos and a short description are enough for a first look.
Can you work on a hospital site such as Zachary Merton Hospital?
Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.
What happens if it rains on the day?
The joint has to be dry, and the air and surface temperature inside the product’s limits. Frost, rain and condensation on steel or concrete can hold up external work, so we plan with the forecast in mind.
Do you cover Atherington?
Yes. Sites across Atherington are covered, and the same phone number covers every area.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
What’s the difference between an expansion joint and a movement joint?
Put simply, it’s a planned break in a wall, slab or deck so the materials can move. Many people call it an expansion joint, and either way it needs a sound seal.
Are your applicators CSCS-carded?
Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.
