Floor joint sealing for Lagness sites
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Floors, slabs and movement joints in Lagness
Lagness sits close to the coast, within about 2 miles. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, so it pays to keep them sealed. The South East is one of the drier parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, and winter de-icing salt on car parks and ramps works into any open joint.
University campuses such as University of Chichester (to the north of Lagness) have car parks, paved walkways and building elevations with movement joints. Sites like Bognor Regis War Memorial Hospital (to the east of Lagness) carry ambulances, deliveries and visitors’ cars over their road and deck joints.
Lagness is about 2 miles west of Bognor Regis, in West Sussex. Any commercial site in Lagness is covered. Across West Sussex, 373 places are covered, Lagness among them. Portsmouth is covered too, some 15 miles away.

What else we do in Lagness
Owners, agents and contractors
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.
Whether you are a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.
Diagnose, treat, sign off
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes a day or more, depending on the metres of joint and how many zones the floor is split into, and our waste is bagged and taken away as we go. If others near Lagness need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- A floor survey records every joint, its edges and what crosses it.
- You receive a fixed quote showing products and phasing.
- Each joint is cut or routed back to clean, sound concrete.
- We extract the dust and prime the faces if the product needs it.
- The joint is filled to its specified depth and trimmed level.
- We hand each phase back when it can take traffic.
Before we start on site
- Point out parking and an unloading spot
- Tell us what induction or permit system the site runs
- For older buildings, check the asbestos register before work
Getting a fixed quote
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, speak to us on 01277 525 020 or email us.
Advice
When something else is needed
Being straight saves everyone time. Fresh joints won’t solve:
- A floor that rocks at the joints, which needs a structural fix
- A failing floor coating, which is a flooring contractor’s job
- Joint edges that have already broken away, which need repairing before filling (we will tell you if so)
If in doubt, phone 01277 525 020 or email us and we will say what we think.
What we seal
- Loading bays
- Construction joints
- Forklift and pallet-truck routes
- Saw-cut induced joints
- Retail and showroom floors
- Joints along racking aisles
Maintenance after handover
After handover, a little attention goes a long way:
- Let us know what the floor is cleaned with
- Keep photographs of joints that look like they’re failing
- Stop forks and pallets being dragged across joints
- Expect fillers on young slabs to need a top-up
Normal floor cleaning is fine once the product has cured. Tell us about aggressive cleaning products or hot washing at quote stage so we choose something that tolerates them.
Regular inspection catches failing fills before the edges go. A phased plan, worst routes first, spreads the work out and keeps on top of the rest.
How the job changes by surface
Loading bays and dock areas
Joints at dock doors need a product that copes with the traffic and the conditions. Phasing is planned around your delivery schedule.
Semi-rigid joint fillers
Semi-rigid fillers are designed to support joint edges under hard wheels. They tolerate little movement so timing matters on newer slabs.
Common problems we fix in Lagness
A soft, flexible sealant on a forklift route can’t hold the arrises up and the edges fail regardless. The opposite mistake happens as well: a stiff filler in a joint that keeps moving splits or comes away from the sides.
Things that typically lead to an enquiry:
- Loading bay joints breaking down
- Old filler gone hard, cracked or loose
- Open saw cuts full of debris
- Sealant pulled out along a truck route
Across sites such as Durban Road Industrial Estate, 2.5 miles east of Lagness, floor and movement joints can be sealed in phases so units keep working.

Questions about Lagness
Is Quarry Lane Industrial Estate, near Lagness, within your area?
Yes. We cover Lagness and the area around it, including industrial estates, business parks and retail parks such as Quarry Lane Industrial Estate. Photos and a short description are enough for a first look.
Does a coastal location like Lagness affect which sealant is used?
It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
How long does a job like this take?
We plan the time on site around your programme and access. You’ll have an expected duration with the quote.
When is resealing likely to be due?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
How do you choose the sealant?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Do you have public liability insurance?
Yes. We’re fully insured, including public liability cover.
