From enquiry to sign-off
Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before we move to the next. Smaller jobs around Offington can be grouped with others nearby. 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.
- A fixed quote follows, naming the sealant and its movement class.
- The failed seal is removed and both faces are cleaned until sound and dry.
- Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
- Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
- Finished joints are checked and backed by our 12-month guarantee.
Preparing the site
- Share your working hours and any access restrictions
- Arrange parking or a loading space
- Send asbestos survey details if the building is pre-2000

Expansion joint sealing in Offington
The seal is what lets a movement joint do its job. When the sealant splits or lets go, the gap fills with dirt and water, the joint can’t close properly and its edges begin to crumble. Dealt with early, it stays a sealant job rather than a concrete or masonry repair. If you are dealing with new sealant over old, now failing and leaks through car park deck joints onto the level below, we can put it right, whatever the surface. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Offington, that means joint design, primers and backing rod as standard.
Smaller community and commercial buildings around Offington have their own movement joints in walls and floors. They tend to be overlooked until something leaks or cracks.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Questions about Offington
Does a coastal location like Offington affect which sealant is used?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Is hospital work, at somewhere like Worthing Hospital, something you do?
Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.
What exactly is a movement joint?
Movement joint is the broad term for any joint built in to let a structure move. In everyday use the two names are often swapped, and the sealing method is much the same.
Can the building stay open while you work?
In the majority of cases, yes. We phase the work so most of the building stays in use.
Do you reseal car park expansion joints?
Yes. Deck and ramp joints are resealed with a trafficable sealant chosen for the movement with bays phased so the car park keeps operating.
Do you take on multi-site work?
Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.
What will the job cost?
Every job gets its own fixed quote. For yours, speak to us on 01277 525 020 or email a schedule or drawings with a description of the work.
Cost factors for movement joints
Each job is priced on its own details. The things that drive the figure:
- Location, for remote and island sites
- The site’s rules and procedures
- How much existing material needs removing
- Phasing around occupants
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.
What we need to price the job
For an accurate fixed quote, we need a clear picture of the site. Send us:
- Whether the building will be occupied during the work
- Any specification or named product
- Where the site is, with the postcode
- Asbestos survey details if the building is older
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.
When it isn’t the sealant
We check first that sealant really is the fix. It won’t put right:
- Cracking or settlement that calls for an engineer’s assessment
- Damaged metal nosings or cover plates over a joint
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
Not sure which it is? You can phone 01277 525 020 or email drawings and photos and we will tell you honestly.
Surfaces we seal
- Podiums and floor movement joints
- Blockwork control joints
- Brickwork movement joints
- Precast concrete panel joints
- Car park decks and ramps
- Cladding panel joints
After the work
Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:
- Treat a small split as a warning, not a cosmetic issue
- Put movement joints on the planned maintenance inspection round
- Record the sealant used and the date in the O&M file
- Clear dirt from joint lines during routine cleaning
Every joint we seal is backed by a 12-month guarantee on workmanship. Keep the handover details, product and date with your O&M records, so the next reseal starts with the facts.
A failed deck joint lets water straight through to the level below. Salty water dripping through stains soffits and lands on parked vehicles. Sealing the joint promptly stops it at source.
When to call us in Offington
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:
- Weathered movement joint sealant that no longer flexes
- Movement joints with split or torn sealant
- Debris jammed in movement joints
- Leaks through car park deck joints onto the level below
Phasing is what makes joint work possible on busy sites such as Goring Business Park (1.8 miles south-west of Offington): one bay, aisle or car park row at a time.
What to look for in a quote
- Will failed sealant be removed rather than covered?
- What the guarantee covers, and for how long
- What site paperwork they can supply
- Will CSCS-carded applicators be on site?
Traffic, movement and joints around Offington
Offington lies within about 2 miles of the sea. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, so a failed joint lets more in and the edges break up sooner. Offington is in the South East, one of the UK’s drier regions. Outside joints in yards and car parks still have to be dry before sealing, and where de-icing salt is spread in winter, open joints let it in.
A healthcare site such as Worthing Hospital, 1.6 miles south-east of Offington, depends on car parks, ramps and service yards whose joints take traffic all day. On a site such as Downlands Business Park (1.1 miles east of Offington), the movement joints are in car park slabs, paving and building elevations.
Offington is about 1 mile north-east of Worthing, in West Sussex. We cover commercial sites throughout Offington. Across West Sussex, 373 places are covered, Offington among them. For work in that direction, see our Brighton page.

Why it’s worth doing now in Offington
Doing joint resealing alongside other planned works can save on access. But joints already letting water in shouldn’t wait for a programme. Urgent joints now, the rest later, is often the sensible plan. For buildings around smaller places like Offington, 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 product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
