Floor joint sealing across Hammersmith

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Floor joint sealing in Hammersmith

We work on warehouse aisles, dock areas, factory floors, retail units and showrooms. Pricing depends on the length of joint, how worn the edges are and when we can get in, and the quote is fixed before we mobilise. Site teams most often ask us about open saw cuts full of debris and scruffy, dirty joint lines on a shop or showroom floor, across retail and showroom floors, loading bays and saw-cut induced joints. A single leaking joint is often how a building in Hammersmith first comes to us: we look at the rest while we’re there and tell you what we find.

London’s floor joints are concentrated in warehouses and trade units, car parks, podiums and decks. In Hammersmith, as everywhere in London, access, loading and the ULEZ all come into the plan.

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant.

For managing agents and facilities managers

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, and our applicators hold CSCS cards.

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

How the quote is worked out

A fixed quote reflects the actual work. It takes account of:

  • Phasing around occupants
  • Removal of failed or old sealant
  • Backing rod, priming and other preparation
  • The site’s rules and procedures

What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.

Sending details for a quote

We can often quote from photographs and a few details. It helps to include:

  • Access details, including height
  • What the building is and how it’s used
  • Your programme or deadline
  • Photos of the joints, close up and from further back

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.

Our process

At the end of each section, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. Planning a London job such as one in Hammersmith starts with access. Send the building rules and access times with your enquiry.

  1. First, the zones and order of work are agreed with you.
  2. Any joints with broken edges are flagged before work starts.
  3. We clear each run back to clean concrete.
  4. The chosen filler or sealant goes in flush with the slab.
  5. Each area is handed back when ready for traffic.

Getting the site ready

  • Arrange parking or a loading space
  • Send any specification or drawings in advance
  • Make sure the joints can be reached

Request a quote

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, speak to us on 01277 525 020 or send photos by email.

Advice

Warehouse floors and decks around Hammersmith

In London, decks, bays and service yards typically have to keep running, so we seal in sections and hand areas back as each cures. Hammersmith has at least three named business or industrial parks inside a 3-mile radius. Their warehouses, yards and car parks are exactly where joints take the most punishment.

Phasing is what makes joint work possible on busy sites such as Stable Way Industrial Estate (1.4 miles north of Hammersmith): one bay, aisle or car park row at a time. Parks like Berghem Mews Business Village (to the north-east of Hammersmith) combine paved areas, car parks and building elevations, each with joints that move. Sites like Charing Cross Hospital, 0.7 miles south-east of Hammersmith, carry ambulances, deliveries and visitors’ cars over their road and deck joints.

Hammersmith is about 1 mile west of Kensington, in Greater London. Our applicators travel to Hammersmith for work on floor joints, handled exactly as we handle every other area. We work across 764 places in Greater London, large and small. Our London page has more on work in that area, about 6 miles away.

Hammersmith: questions and answers

Is Berghem Mews Business Village, near Hammersmith, within your area?

Yes. Estates, retail parks and business parks around Hammersmith, Berghem Mews Business Village among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

Can you work in a London building with booked loading and goods-lift slots?

Yes, we plan every London job around the building’s own access rules. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly.

Do you guarantee industrial floor joints?

Every job has our 12-month guarantee. It applies to our workmanship rather than structural movement or accidental damage.

Do your applicators hold CSCS cards?

Yes. Our applicators hold CSCS cards, which many sites require.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance.

Who decides which product is used?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Do you hold CHAS accreditation?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

General trades versus a specialist

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Different surfaces, different methods

Construction joints

Construction joints, sometimes called day joints, mark where one pour ended and the next began. They can move more than saw cuts and that shapes the choice of filler or sealant.

Loading bays and dock areas

Bays can be treated one or two at a time so goods in and out carry on. Your site hours and access windows set the order.

Why it’s worth doing now in Hammersmith

Holding off until the whole floor can close can take a long time. Phased in zones, the busiest routes can be treated first while the rest of the floor carries on. In a London building, a failed joint rarely affects only one party: water travels through shared structures, and a small leak becomes a dispute between occupiers. Putting it right early is less disruptive than dealing with the consequences.

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we’ll explain how it’s made up.
