Expansion joint sealing for businesses in Crews Hill

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

Your questions answered

Do you work in London buildings with loading restrictions?

Yes, we plan every London job around the building’s own access rules. Share the building’s contractor rules and we will work to them. All of Greater London is inside the ULEZ, and our planning allows for it

Do you cover business parks and estates near Crews Hill, such as Sopers Road Industrial Estate?

Yes. Estates, retail parks and business parks around Crews Hill, Sopers Road Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.

Do you guarantee expansion joint work?

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

How do I request a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.

Will you come and look before quoting?

That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.

Do you have public liability insurance?

Yes. We’re fully insured, including public liability cover.

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

Expansion joint sealing for commercial buildings in Crews Hill

Our movement joint work takes in walls, panels, decks and floors: brickwork and blockwork joints, precast and cladding panel joints, concrete joints, car park decks and ramps, podiums and floor movement joints. The product depends on the movement, the weather and anything that runs over it. If you are dealing with debris jammed in movement joints and leaks through car park deck joints onto the level below, we can help, whatever the surface. One point of contact handles commercial sealant work in Crews Hill from the first photographs to the final walk-round, for single jobs and planned programmes alike.

Areas such as a loading bay or car park deck in Crews Hill 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.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

How a job runs

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Most London premises stay occupied while we’re 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 the joints are inspected, widths measured and the type of failure noted.
  2. A fixed quote names the sealant we propose and its movement class.
  3. Phasing is agreed so decks, floors or entrances can stay in use where needed.
  4. We strip the old sealant or filler and prepare each face until it’s sound and dry.
  5. Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
  6. We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.

Before we start on site

  • Arrange parking or a loading space
  • Send your site hours and access windows
  • Move anything stored against the joints

Warehouse floors and decks around Crews Hill

London car parks, loading bays and podium decks often can’t close for long, which is why we work a few bays at a time. Crews Hill has at least three named business or industrial parks inside a 3-mile radius. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.

Access in Crews Hill needs thought: the ULEZ covers all of Greater London, and loading and parking are rarely simple. If you manage units on an estate such as Sopers Road Industrial Estate, which lies north of Crews Hill, the floor joints under forklifts and pallet trucks and the slab joints in the yard are the ones to watch. For a school such as St John's CofE Primary School, playground and building joints can be done in the holidays.

Surface by surface

Podium joints

Podium joints often sit within a waterproofing system. Where the specification calls for sealant, we reseal and flag it if the membrane looks like the source.

Cladding panel joints

Metal and composite panels shift considerably as temperatures change. The joints need a low-modulus sealant with enough movement capability.

Looking after the joints

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:

  • Plan racking layouts so feet don’t land on a joint
  • Keep stones and debris out of open joint lines
  • Treat a small split as a warning, not a cosmetic issue
  • Keep product details with the building records for the next reseal

Add every elevation, deck and floor joint to your inspection round. Early splits and edges starting to lift show up on a routine check. If anything looks wrong, ring 01277 525 020 or email us with photographs.

A failed deck joint lets water straight through to the level below. That water often carries de-icing salts with it, which is bad news for the concrete and the people parking below. Resealing early limits the damage.

What sealant work can’t fix

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

  • Joints too narrow for the movement, which need redesigning by the engineer
  • Broken or spalled joint edges, which need repairing before any sealant goes in
  • Leaks coming from the membrane rather than the joint seal

If in doubt, ring 01277 525 020 or send photos by email and we’ll say what we think before you book.

Surfaces we seal

  • Blockwork control joints
  • Brickwork movement joints
  • Precast concrete panel joints
  • Cladding panel joints
  • Car park decks and ramps
  • Podiums and floor movement joints

How the quote is worked out

What shapes the price:

  • Site requirements such as inductions and permits
  • Removal of failed or old sealant
  • How much there is to seal
  • Backing rod, priming and other preparation

The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

Sending details for a quote

To price the job accurately, we need to understand the site. Send us:

  • Specification clauses that apply
  • Anything awkward about access or site hours
  • Rough lengths or quantities, or drawings if you have them
  • Photos of the joints, close up and from further back

Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.
