Expansion joint sealing for businesses in Enfield Lock

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

Leave it or put it right?

Re-sealing with the same product that failed is often a false economy. If the joint is too narrow or the product wrong for the movement, it needs a different approach. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Expansion joint sealing for commercial buildings in Enfield Lock

Every structure moves a little, all the time: they expand in the heat, shrink as they dry, and shift under load. Expansion and movement joints are built in so the structure can move without cracking and the seal across each one keeps out water and grit. We seal and reseal movement joints in walls, panels, decks and floors for buildings in Enfield Lock. Site teams most often ask us about debris jammed in movement joints and weathered movement joint sealant that no longer flexes, across cladding panel joints, podiums and floor movement joints and brickwork movement joints. Facilities teams, main contractors and managing agents in Enfield Lock tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Areas such as a loading bay or car park deck in Enfield Lock usually have to stay in use. We work through joints a section at a time, closing small areas in turn, at times agreed with the building manager.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Building owners, agents and FMs in Enfield Lock

For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules.

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

FAQs: Enfield Lock

Do you work in London buildings with loading restrictions?

Yes, we plan every London job around the building’s own access rules. Say when the building is occupied and when it’s quiet, and we will plan accordingly. The ULEZ covers the whole of Greater London, which we allow for

Does your area include sites such as Waterways Business Centre, near Enfield Lock?

Yes, sites like Waterways Business Centre are within our area, along with the rest of Enfield Lock. A few photos and the unit address let us price the work.

Do the joint edges need to be sound before sealing?

Sound edges are essential. Where they’ve broken up, we will tell you they need repairing first.

Are expansion joints and movement joints the same thing?

The terms overlap a great deal. Both let materials grow and shrink with temperature, moisture and load, and the seal across it keeps water and debris out.

Do you need to see the site first?

Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit.

What guarantee do you give on joint sealing?

It’s backed by our 12-month guarantee. If a joint we sealed fails inside the 12 months, let us know.

Do you take on multi-site work?

Yes. A group of buildings can go on one quote, and you deal with one contact throughout.

Keeping the joints sound

After handover, these steps help:

  • Raise snow-clearing blades over deck joints where possible
  • Avoid parking heavy plant or pallets on joint lines
  • Reopen bays and walkways only after the stated cure time
  • Note which joints were done, when, and with what

Snow ploughs and scrapers catch on joint lines. Lifting the blade at each joint avoids tearing the bead.

When one joint fails, others of the same age are rarely far behind. Inspecting the whole run is worth the effort. We’ll tell you which movement joints need doing now and which can wait.

What sets the cost

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

  • The total length or number of joints
  • Whether old sealant has to be cut out first
  • Which sealant the job calls for
  • The size and state of each joint

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we’ll explain how it’s made up.

Before you send an enquiry

Good information means a firmer quote. Helpful details to send:

  • Access details, including height
  • Asbestos survey details if the building is older
  • Your programme or deadline
  • Any specification or named product

Send us photos, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.

Surface by surface

Concrete and precast panel joints

Joints between precast panels open and close with temperature and loading. We use a sealant classed for the movement, laid over backing to depth.

Brickwork and blockwork joints

Masonry faces are often porous, dusty or crumbly. Faces are prepared and primed wherever the sealant maker calls for it before the bead goes in.

Joints that move: notes for Enfield Lock

Less than 3 miles from Enfield Lock there are at least three named estates and business parks. Sites like these are full of saw-cut floor joints, yard slabs and car park joints. Basement car parks and service yards in London tend to be in use all working day, so we seal in sections and hand areas back as each cures.

Another example is Brimsdown Industrial Estate, which lies south of Enfield Lock, where floors and yards would be done in stages around the occupiers. Schools such as Prince of Wales Primary School have movement joints in their walls and floors that are easy to overlook. At a retail site such as Enfield Highway Shopping Centre, which lies south-west of Enfield Lock, trolleys, cages and cars run over floor and slab joints all day.

Enfield Lock is about 2 miles south-west of Waltham Abbey, in Greater London. We send applicators to Enfield Lock for movement joints. Enfield Lock is one of 764 places in Greater London on our list for movement joints. Our London page has more on work in that area.

Sites close to Enfield Lock are covered too, including Enfield Island Village (1 mile east), Freezywater (1 mile north), Enfield Wash (1 mile west), Brimsdown (1 mile south) and Enfield Highway (1 mile south-west). Further afield, our area takes in London (12 miles south), City of Westminster (12 miles south-west), Marylebone (12 miles south-west), Kensington (14 miles south-west), St Pancras (11 miles south) and Shoreditch (10 miles south).

On site: what to expect

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. For a job in Enfield Lock, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. We compare each joint’s width with the movement and the sealant’s capability.
  3. Old sealant and debris are cut out of every joint.
  4. Edges are checked, and we tell you if any need repairing before sealing.
  5. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Each area is handed back after its cure time, under our 12-month guarantee.

Preparing the site

  • Let building users know which areas are affected
  • Make sure the joints can be reached
  • Send any specification or drawings in advance
