How we handle floor joint sealing in Northwood
For sites in Northwood and across Greater London, the process is short: you send details, we send a fixed quote, the joints are done and the 12-month guarantee follows. A rough length of joint, photos of the worst areas and a site plan let us give a quick quote, or we can arrange a site visit. We work on saw-cut induced joints, loading bays and retail and showroom floors, and the failures we’re asked to look at most are brittle joint filler breaking up and broken arrises where pallet trucks cross. A specialist sealant contractor works differently from a general builder: on jobs in Northwood, preparation and product choice get the time they need.
London’s floor joints are concentrated in warehouses and trade units, car parks, podiums and decks. Planning a job in Northwood means thinking about access, loading times and the ULEZ as well as the joints.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Honest limits
Not every problem is a sealant problem, and we’re upfront when that’s the case. It won’t fix:
- Level or flatness problems across the floor
- A floor that rocks at the joints, which needs a structural fix
- Structural cracking in the slab

How a job runs
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Planning a London job such as one in Northwood 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’ll schedule to suit.
- Each area is assessed for joint width, arris damage and the wheels that cross it.
- You get a fixed quote with the product and the phasing set out.
- Each joint is cleared of old fill and dirt and taken back to clean, sound edges.
- We vacuum each run and prime it if the chosen product requires a primer.
- We fill each joint to depth and finish it flush so wheels roll straight across.
- The area is handed back once it has cured enough to take traffic.
What we need from you
- Explain the parking and delivery arrangements
- Send asbestos survey details if the building is pre-2000
- Tell us what induction or permit system the site runs
Request a quote
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.
Advice
How the job changes by surface
Loading bays and dock areas
Bays can be treated one or two at a time so deliveries keep moving. Your site hours and access windows set the order.
Retail and showroom floors
Retail joints see trolleys, footfall and scrubber-driers. We pick a filler or sealant to suit and the appearance is part of the brief.
Northwood: questions and answers
Do you take on work at healthcare sites like Watford General Hospital?
Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.
Can you cope with the access rules in a London building?
Yes. Inductions, permits and timed loading are routine for us in London. Send the building rules and access times with your enquiry. We allow for the ULEZ, which covers every borough
What if there’s asbestos in the old mastic?
Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
Do you hold CHAS accreditation?
Yes. We’re CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
Do you repair broken joint edges?
Filling against broken edges doesn’t last. We will tell you if the joint edges need repairing first, so you can decide how to proceed.
What site paperwork can you supply?
Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.
Which is better for warehouse joints, filler or sealant?
It depends on the traffic and the movement. Forklift routes generally call for a semi-rigid filler that holds the arrises, while joints that move more take a flexible sealant.
What happens if it’s left?
A floor coating laid over open joints soon cracks along the joint lines. The joints have to be filled or sealed as joints before or alongside any coating work. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.
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 will put a fixed figure on it.

Common problems we fix in Northwood
Joints near dock doors see colder air, rain blown in and water off vehicles on top of the heaviest turning movements. They are often the first on a site to break down.
Look out for the following:
- Filler that has parted from one face
- Brittle joint filler breaking up
- Soft sealant dragged out of trafficked joints
- Grimy joint lines spoiling a showroom floor
In a school such as Frithwood Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak.
What to look for in a quote
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
