Floor joint sealing near Upper Walthamstow

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

Our process

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. Planning a London job such as one in Upper Walthamstow starts with access. Give us the hours we can be on site and we will schedule to suit.

  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.

Preparing the site

  • Explain the parking and delivery arrangements
  • Clear stock, furniture or equipment away from the joints
  • Tell us your opening times and when work is allowed

Getting a fixed quote

Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to call the office on 01277 525 020 or email the details over.

Floor joint sealing for commercial buildings in Upper Walthamstow

Open joints take a beating from forklift and pallet-truck wheels. Each crossing knocks the unsupported edge until a crisp saw cut becomes a wide, broken groove. A properly filled joint carries the wheel over and protects both arrises. It also smooths the route for drivers and stock. Site teams most often ask us about chipped and spalling edges along forklift routes and old filler gone hard, cracked or loose, on forklift and pallet-truck routes, joints along racking aisles and loading bays. One point of contact handles commercial sealant work in Upper Walthamstow from the first photos to the final walk-round, for single jobs and planned programmes alike.

Most London buildings can’t shut a car park, loading bay or warehouse floor for long. Joints are done in sections, with bays coned off one after another, so the site keeps operating, at times agreed with the building manager.

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Leave it or put it right?

Painting or coating straight over joints rarely lasts. Joints need their own treatment, whether or not the floor is coated. In Upper Walthamstow, each extra visit means more notices, permits and disruption, so cutting the old sealant out fully and doing it right once is the better route.

What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a quote once you have the details.

Your questions answered

Yes. We cover Upper Walthamstow, and the simplest way to start is to call 01277 525 020 or send photos by email.

Can the sealant be colour-matched?

In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.

Is it normal for joint filler to separate?

It can be shrinkage, contamination on the joint faces or a product unsuited to the movement. We look at which it is before recommending anything.

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.

When it isn’t the sealant

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

  • Uneven floors that need grinding or levelling
  • Joint edges that have already broken away, which need repairing before filling (we’ll tell you if so)
  • Unstable slabs moving under traffic

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 before you book.

What we seal

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

Maintenance after handover

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Put loading bays at the top of the list
  • Tell us about strong cleaning chemicals before we quote
  • Clear packed debris from open joints regularly
  • Make joint checks part of your floor inspections

Dragged forks and pallets gouge joints and edges alike. Even a well-filled joint can be damaged by steel scraping along it.

Edges tend to break slowly at first, then quickly. Once the first piece is out, wheels drop further and hit harder so early treatment saves a lot of trouble.

How the job changes by surface

Flexible floor sealants

Where joints move more, a flexible polyurethane floor sealant is often used. They give less edge support than semi-rigid fillers, so they suit lighter traffic or movement joints.

Construction joints

Where a day joint crosses a truck route, its edges take heavy punishment. We look at how much they are moving before choosing the treatment.
