Floor joint sealing for commercial buildings in St John's Wood
Some joints reach us with their edges already broken. Filling against a crumbled arris won’t hold for long, so we’ll tell you if the joint edges need repairing first and explain how it affects the programme. We work on construction joints, saw-cut induced joints and loading bays, and the usual reasons a site gets in touch are open saw cuts full of debris and untidy open joints in a retail unit. For commercial sealant work in St John's Wood, you deal with one contact from quote to sign-off, whether it’s one building or several.
London’s floor joints are concentrated in warehouses and trade units, car parks, podiums and decks. Planning a job in St John's Wood means thinking about access, loading times and the ULEZ as well as the joints.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

Questions about St John's Wood
Do you take on jobs in St John's Wood where loading and access are tightly controlled?
Yes. Inductions, permits and timed loading are routine for us in London. The building manager’s rules go straight into our method.
Can you work on a hospital site such as Hospital of St John and St Elizabeth?
Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Why is there a gap next to the joint filler?
On newer slabs, the concrete keeps shrinking after the joints are filled, so a semi-rigid filler can part from one face. It is usually dealt with by topping up.
Should floor joints be filled or sealed?
The answer comes from the traffic and the joint’s movement. Trafficked joints on truck routes typically need a semi-rigid filler to support the edges, while joints that move more take a flexible sealant.
Are you fully insured?
Yes. Our insurance certificate can be sent alongside the quote.
How many days will you need on site?
That varies with the scale of the job, though a typical visit normally takes a day for smaller units, with bigger warehouse floors programmed over several visits. For bigger or phased jobs, we’ll set out a timescale with the quote.
What guarantee do you give on joint filling?
Every job has our 12-month guarantee. It covers our workmanship, not later slab movement or damage from impacts.

From enquiry to sign-off
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Planning a London job such as one in St John's Wood starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we will schedule to suit.

- We point out joints whose edges need repairing first.

What we can’t put right
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Worn screed or surface finishes
- Unstable slabs moving under traffic
- Structural cracking in the slab
If in doubt, call 01277 525 020 or use the quote form and we’ll say what we think.
Surfaces we seal
- Joints along racking aisles
- Loading bays
- Construction joints
- Retail and showroom floors
- Forklift and pallet-truck routes
- Saw-cut induced joints
Work for main contractors and building owners
Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.
Different surfaces, different methods
Retail and showroom floors
In retail, joints take trolleys, castors and cleaning machines rather than forklifts. The product is chosen for that traffic and the finish matters as much as the performance.
Loading bays and dock areas
We usually work through dock areas a few bays at a time so deliveries keep moving. Your site hours and access windows set the order.
What sets the cost
Before we quote, we look at:
- Which sealant the job calls for
- Joint width, depth and condition
- Phasing around occupants
- Removal of failed or old sealant
There’s no price list, since every building and every scope is different. Call for a quote and we’ll price your job on its own details.
Details that help us quote
A few photos plus some basic facts will normally do. Please tell us:
- Whether the building will be occupied during the work
- When you need the work done
- Approximate linear metres or a joint schedule
- Specification clauses that apply
Pricing a project or setting a maintenance budget? We’ll quote against your scope and drawings that you can work with. For a chat about it beforehand, call the office on 01277 525 020 or email a schedule or drawings.
After the work
Cleaning and maintenance staff play a part too. Pass these on to them:
- Record damaged joints with a photo and a location
- Walk the main routes and inspect joint lines on a regular cycle
- Remind operators to lift rather than drag
- Treat loading bay joints first if they’re failing
Ask drivers not to drag forks or pallets along the floor. Even a well-filled joint can be damaged by steel scraping along it.
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.
