Floor joint sealing for commercial buildings in Old Chiswick

We have been sealing commercial joints since 2005. Applicators carry CSCS cards and work to your site rules, and the business is CHAS accredited and a Constructionline member, with public liability insurance in place. Completed joints come with a 12-month guarantee on our workmanship. We work on joints along racking aisles, construction joints and retail and showroom floors, and the usual reasons a site gets in touch are open saw cuts full of debris and flexible sealant torn out by wheels. Searching for sealant specialists in Old Chiswick? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

Areas such as a loading bay or car park deck in Old Chiswick normally have to stay in use. Joints are done in sections, with bays coned off one after another, so the site keeps operating, at times agreed with the building manager.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

What we can’t put right

Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is any of the following:

  • A failing floor coating, which is a flooring contractor’s job
  • Spalled arrises, which need an edge repair first
  • A floor that rocks at the joints, which needs a structural fix

If in doubt, call the office on 01277 525 020 or email us and we’ll say what we think before you book.

Surfaces we seal

  • Forklift and pallet-truck routes
  • Retail and showroom floors
  • Construction joints
  • Saw-cut induced joints
  • Loading bays
  • Joints along racking aisles

Common questions from Old Chiswick clients

Would you work within a site like Charing Cross Hospital?

Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Do you work in London buildings with loading restrictions?

Yes, most London buildings have access rules of some kind, and we plan around them. Share the building’s contractor rules and we will work to them. All of Greater London is inside the ULEZ, and our planning allows for it

Do you seal on top of existing sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

How do you choose the sealant?

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 use semi-rigid filler or flexible sealant on floor joints?

We decide joint by joint. Hard wheels need edge support, which points to a semi-rigid filler and perimeter or movement joints need flexibility. The quote sets out what goes where.

Do you work in Old Chiswick?

Yes. We cover Old Chiswick, and the simplest way to start is to phone 01277 525 020 or email drawings and photos.

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. A top-up normally puts it right.

Where floor joints take the most wear near Old Chiswick

The 3 miles around Old Chiswick take in at least three named trading estates, business parks or retail parks. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest. In London, decks, bays and service yards normally have to keep running, so the work is broken into short sections agreed with the building manager.

Phasing is what makes joint work possible on busy sites such as Berghem Mews Business Village (1.6 miles north-east of Old Chiswick): one bay, aisle or car park row at a time. For estates staff at a university like Richmond American University London, 1.1 miles to the north-west of Old Chiswick, building and paving joints are part of the planned maintenance list. For a school such as The William Hogarth Primary School, playground and building joints can be done in the holidays.

Diagnose, treat, sign off

Site rules come first: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, we take the joints in the sequence agreed with you. In Old Chiswick, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.

  1. We walk the floor and mark up joint widths, edge damage and traffic routes.
  2. The treatment and the zones are set out in a fixed quote.
  3. Old fill and packed debris come out until both faces are sound.
  4. We extract the dust and prime the faces if the product needs it.
  5. The joint is filled to its specified depth and trimmed level.
  6. Zones reopen once cured and the work moves on.

Before we start on site

  • Tell us which areas need to stay in use
  • Explain the parking and delivery arrangements
  • Let building users know which areas are affected

Getting a fixed quote

Advice

Why it’s worth doing now in Old Chiswick

Every jolt over a broken joint passes into the truck, the load and the driver. Wheels and bearings wear faster and loads can shift, adding costs nobody plans for. A filled joint takes most of that out. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

What you get with us

  • Public liability insurance in place
  • One contact handling all your sites
  • 12 months’ guarantee on every job

Different surfaces, different methods

Semi-rigid joint fillers

On industrial routes, a semi-rigid filler is often the right choice. We place them to depth and trim them level with the slab.

Loading bays and dock areas

We usually work through dock areas a few bays at a time so deliveries keep moving. Tell us your site hours and access windows and we’ll plan around them.

What sets the cost

Your fixed quote is built from the real scope. It takes account of:

  • Location, for remote and island sites
  • The total length or number of joints
  • Backing rod, priming and other preparation
  • Removal of failed or old sealant

A quote for floor joints depends on quantities, condition and access, plus any specification you are working to. Call for a quote.

Before you send an enquiry

A few photographs plus some basic facts will normally do. Please tell us:

  • Whether an asbestos survey exists
  • A wide shot and a close-up of the area
  • Anything awkward about access or site hours
  • Any specification or named product

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.
