Floor joint sealing for Lower Clapton sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

What affects the price in Lower Clapton

There’s no standard rate for sealant work, because every site is different. What we look at:

  • Any access equipment needed
  • Induction, permit and paperwork requirements
  • Location, for remote and island sites
  • Whether old sealant has to be cut out first

There’s no price list, because the scope varies so much from one building to the next. Call for a quote.

Before you send an enquiry

To price the job accurately, we need a clear picture of the site. Send us:

  • Whether an asbestos survey exists
  • Your programme or deadline
  • The product your specification calls for
  • What the building is and how it’s used

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, call 01277 525 020 or email the details over.

About our floor joint sealing in Lower Clapton

A working floor can rarely be closed for days on end, so we phase the work aisle by aisle or bay by bay. Tell us your site hours and access windows and we will plan around them, with goods still moving in the areas we aren’t in. We work on loading bays, forklift and pallet-truck routes and joints along racking aisles, and the usual reasons a site gets in touch are joint fill separating from the concrete and joint edges breaking up under truck wheels. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Lower Clapton it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Around Lower Clapton, as across London, joints are under constant load, from basement car parks and loading bays to podium decks and busy mall floors. When a joint fails, grit and water get in and the arrises start to break up, so it pays to act early.

A 12-month guarantee applies to all our work in Greater London. Should something we installed fail, call 01277 525 020 or use the quote form and we’ll come back to it.

What we can’t put right

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Unstable slabs moving under traffic
  • Spalled arrises, which need an edge repair first
  • Cracks across panels caused by settlement or overload

Not sure which it is? You can speak to us on 01277 525 020 or email drawings and photos and we’ll tell you honestly.

Joints and surfaces we work on

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

Signs you need floor joint sealing in Lower Clapton

Small, hard wheels put a lot of load through a very small area. Crossing an open joint, the wheel drops and knocks the opposite arris and those knocks chip the edge apart bit by bit.

It’s worth sending us details if you spot any of the following:

  • Scruffy, dirty joint lines on a shop or showroom floor
  • Flexible sealant torn out by wheels
  • Unfilled floor joints collecting dirt and grit
  • A gap opening alongside old joint filler

A campus such as Loughborough University London, 1.1 miles to the east of Lower Clapton, has long runs of movement joint in its buildings, decks and paving.

Before you book anyone

  • Can the work be phased to keep areas open?
  • Will failed sealant be removed rather than covered?
  • Which product they’ll use, and why it suits the joint
  • How the joint faces will be prepared and primed

Our contractor checklist

Common questions from Lower Clapton clients

Will you take on work at estates like Bayford Street Industrial Centre, close to Lower Clapton?

Yes, sites like Bayford Street Industrial Centre are within our area, along with the rest of Lower Clapton. Send details of the unit and the work through our quote form for a quick quote.

Can you take on a job at a hospital such as Homerton University Hospital?

Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.

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.

How do you choose the sealant?

A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Is it normal for joint filler to separate?

Young concrete carries on shrinking for a long time and a stiff filler can separate down one side. It is normally dealt with by topping up.

Is it fine to apply new sealant on top of old?

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

Do you offer coloured sealant?

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.

How the job changes by surface

Forklift and pallet-truck routes

Open route joints are hard on equipment and drivers. Filling them gives a smoother run and protects the floor.

Isolation joints at walls and columns

Where racking or plant sits near column joints, access is agreed before we start.

Floor joint sealing in Lower Clapton: the local picture

The 3 miles around Lower Clapton take in at least three named trading estates, business parks or retail parks. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic. 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 Victoria Park Industrial Centre (1.1 miles south-east of Lower Clapton): one bay, aisle or car park row at a time. Retail centres such as Leyton Mills Retail Park (1.6 miles east of Lower Clapton) have floors, service yards and car parks with joints under constant traffic.

Lower Clapton is about 2 miles north-east of Hoxton, in Greater London. Lower Clapton sits inside our coverage and the rest of Greater London, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Across Greater London, 764 places are covered, Lower Clapton among them.

We cover the E5, E9 and E8 postcode districts. We cover commercial and managed buildings on Glyn Road, Rowe Lane and Ward Lane. If your building is just outside Lower Clapton, we cover Homerton (1 mile north), Hackney (1 mile south), Clapton (1 mile north-west), Lea Bridge (1 mile north) and Hackney Marshes (1 mile north-east). Further afield, our area takes in London (4 miles south-west), City of Westminster (5 miles south-west), Marylebone (5 miles south-west), Kensington (8 miles south-west), St Pancras (4 miles south-west) and Walthamstow (3 miles north-east).

For a walk, there’s Tower Hill and Hollow Pond.

What happens if it’s left?

Waiting for a site-wide shutdown often means the joints keep getting worse. Zone by zone, the worst aisles can be dealt with now and the remainder follows on a plan that suits you. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.

The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site rules also count.

What you get with us

  • One phone line for London, the South East and Scotland
  • Joints cleaned back to sound surfaces
  • Clear, fixed quotes
  • Health and safety: CHAS accredited

How a job runs

Site rules come first: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you. All of Greater London is in the ULEZ, and kerbside space in Lower Clapton can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.

  1. We agree the traffic routes and phasing with your site team.
  2. We point out joints whose edges need repairing first.
  3. We clear each run back to clean concrete.
  4. The chosen filler or sealant goes in flush with the slab.
  5. You get a time for each zone to reopen.

Getting the site ready

  • Make sure the joints can be reached
  • Send asbestos survey details if the building is pre-2000
  • Point out any areas we must not close

Getting a fixed quote

A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or give us a call on 01277 525 020 or send details through our quote form to discuss it first.
