Floor joint sealing across Preston

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

What the job involves on each surface

Forklift and pallet-truck routes

Truck routes take traffic all day, so their joints wear fastest. A semi-rigid filler is common here because it supports the arrises under hard wheels.

Flexible floor sealants

Polyurethane floor sealants are available in a range of colours, and we will confirm what the specified product offers.

About our floor joint sealing in Preston

Some joints reach us with their edges already broken. Filling against a crumbled arris won’t hold for long, so we will tell you if the joint edges need repairing first and explain how it affects the programme. Site teams most often ask us about joint fill separating from the concrete and untidy open joints in a retail unit, across retail and showroom floors, forklift and pallet-truck routes and joints along racking aisles. Most enquiries from Preston start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

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 behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant.

When something else is needed

We check first that sealant really is the fix. It won’t put right:

  • A failing floor coating, which is a flooring contractor’s job
  • Slab panels that rock or move under load
  • Joint edges that have already broken away, which need repairing before filling (we’ll tell you if so)

If in doubt, ring 01277 525 020 or email the details over and we will say what we think.

What we seal

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

Signs you need floor joint sealing in Preston

Unfilled joints soon pack with grit, shrink-wrap scraps and pallet splinters. That debris is hard and levers at the edges as wheels pass, speeding up the damage.

If one of these sounds familiar, it’s time for a closer look:

  • Filler that has parted from one face
  • Sealant pulled out along a truck route
  • A rough ride across broken joints
  • Open saw cuts full of debris

Phasing is what makes joint work possible on busy sites such as Stadium Retail Park (0.9 miles south-east of Preston): one bay, aisle or car park row at a time.

Choosing a commercial sealant contractor

When to bring in a specialist

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Slabs, ramps and loading bays in Preston

Less than 3 miles from Preston there are at least three named estates and business parks. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic. Basement car parks and service yards in London tend to be in use all working day, so the work is broken into short sections agreed with the building manager.

On a site such as East Lane Business Park, 0.5 miles south-west of Preston, the movement joints are in car park slabs, paving and building elevations. Hospital campuses such as Northwick Park Hospital (to the west of Preston) grow in stages, leaving movement joints wherever new blocks meet old.

Preston is about 1 mile north of Wembley, in Greater London. Businesses, contractors and managing agents in Preston use us for work on floor joints, as part of our coverage of Greater London. Across Greater London, 764 places are covered, Preston among them. Our London page has more on work in that area.

Cost factors for floor joints

Each job is priced on its own details. The main factors are:

  • Location, for remote and island sites
  • How much there is to seal
  • Site requirements such as inductions and permits
  • Any access equipment needed

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Before you send an enquiry

Diagnosis starts before we arrive. Let us know:

  • Photos of the joints, close up and from further back
  • How the joints are reached, and at what height
  • Whether an asbestos survey exists
  • Your programme or deadline

A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or phone 01277 525 020 or email us if you’d rather talk the job through.

Common questions from Preston clients

Do you work in London buildings with loading restrictions?

Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Send the building rules and access times with your enquiry. All of Greater London is inside the ULEZ, and our planning allows for it

Would you work within a site like Northwick Park Hospital?

Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Are you CHAS accredited and on Constructionline?

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

Is it normal for joint filler to separate?

Separation usually comes from slab shrinkage, poor preparation or the wrong product. We look at which it is before recommending anything.

Will your applicators have CSCS cards?

Yes. If you need card details for site access, let us know and we’ll send them with the quote.

What guarantee do you give on joint filling?

There is a 12-month guarantee on our workmanship and the work is covered by public liability insurance.

Will you just go over the old 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 a job runs

In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before the next one starts. Most London premises stay occupied while we are on site, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.

  1. First comes a walk of the floor to record joint sizes, broken edges and traffic routes.
  2. You get a fixed quote with the product and the phasing set out.
  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. Filler or sealant goes in to the right depth and is finished flush with the slab.
  6. We tell you when each zone can carry trucks again and move on to the next.

Preparing the site

  • Clear stock, furniture or equipment away from the joints
  • Have the specification and drawings to hand
  • Send asbestos survey details if the building is pre-2000
