Floor joint sealing for commercial buildings in Windsor

A working floor can rarely be closed for days on end, so the work is split into zones and treated one area at a time. Share your site hours and access windows and the programme is built around them, with goods still moving in the areas we aren’t in. We work on forklift and pallet-truck routes, construction joints and retail and showroom floors, and what we are called in for most is brittle joint filler breaking up and drivers complaining about joints on a route. Facilities teams, main contractors and managing agents in Windsor tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Car parks and yards in towns like Windsor take tyre loads and, in winter, de-icing salt. Resealing before the edges break up is far less disruptive than repairing them later.

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 are clear about what is covered before work starts.

Why it’s worth doing now in Windsor

While the arrises are intact, filling a joint is straightforward. Wait until the edges have spalled and the concrete needs repairing before the joint can be filled, with longer closures to match. In a town like Windsor, a split, stained or mouldy joint is often the first thing visitors notice. Fresh sealant makes a building look maintained.

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 you’ll have a fixed figure to work with.

How a job runs

When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work typically takes a day for smaller units, with bigger warehouse floors programmed over several visits. For a town like Windsor, we try to group jobs for the same client into one visit. Give us your access times and we’ll fit the work in.

  1. Each area is assessed for joint width, arris damage and the wheels that cross it.
  2. A fixed quote follows, listing the treatment for each area and the order of work.
  3. Old filler, debris and contamination are cut or routed out back to clean concrete.
  4. Dust is extracted from the joint and primer applied where the manufacturer specifies it.
  5. The chosen product is placed to its specified depth and trimmed level with the floor.
  6. The area is handed back once it has cured enough to take traffic.

Getting the site ready

  • Confirm the product named in the specification
  • Flag any permit to work we’ll need
  • For older buildings, check the asbestos register before work

We plan shop-floor work so trading can continue. Give us your opening pattern and access windows and the phasing follows.

Flexible floor sealants

A flexible sealant suits perimeter and movement joints away from the heaviest traffic. Closed-cell backing rod goes in first, keeping the bead shallow and gripping only the two faces.

FAQs: Windsor

Will you take on work at estates like Portland Business Park, close to Windsor?

Yes, sites like Portland Business Park are within our area, along with the rest of Windsor. Photos and a short description are enough for a first look.

Must our site in Windsor stop work while the joints are done?

In the majority of cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. We agree the sequence and timings with you before we start.

Do you work in Windsor?

Yes. Sites across Windsor are covered, with one number for every area we cover.

Should floor joints be filled or sealed?

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.

Do your applicators hold CSCS cards?

Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.

Can the warehouse stay open while you work?

The work is phased. Areas are taken out of use a section at a time around the site hours and access windows you give us.

Is colour matching possible?

Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We will confirm the colours available for the specified product.

Common problems we fix in Windsor

Joints near dock doors see colder air, rain blown in and water off vehicles on top of the heaviest turning movements. That is usually where joint failure starts.

Things that normally lead to an enquiry:

  • Grimy joint lines spoiling a showroom floor
  • Loading bay joints breaking down
  • Brittle joint filler breaking up
  • Saw-cut joints left open and packed with grit

In a school such as St Edward's Catholic First School, movement joints in brick, block and hall floors tend to be forgotten until they leak.

Before you book anyone

  • How they’ll work around occupants
  • Whether their applicators hold CSCS cards
  • Will failed sealant be removed rather than covered?
  • How joint depth will be controlled

Questions to ask before you appoint anyone

Where floor joints take the most wear near Windsor

At about 23 miles from central London, Windsor is within reach of the capital. The South East has large numbers of industrial estates and warehouses along the motorway corridors, and their floor joints take forklift and pallet-truck traffic all day. The 3 miles around Windsor take in at least three named trading estates, business parks or retail parks. Sites like these are full of saw-cut floor joints, yard slabs and car park joints.

Business parks such as Portland Business Park (2.3 miles east of Windsor) have car parks, paved areas and long brick and panel elevations, all with movement joints. Phasing is what makes joint work possible on busy sites such as Slough Retail Park (2.5 miles north of Windsor): one bay, aisle or car park row at a time.

Windsor is about 3 miles south of Slough, in Windsor and Maidenhead. Across the SL4 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Our Windsor and Maidenhead coverage takes in 60 places, large and small. Reading is covered too, some 15 miles away.

When it isn’t the sealant

Being straight saves everyone time. New sealant won’t cure:

  • A floor that rocks at the joints, which needs a structural fix
  • Uneven floors that need grinding or levelling
  • Broken concrete either side of the joint

If you’re not sure, just speak to us on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer.
