Expansion joint sealing across Colchester

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

Doing it in-house

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

How we handle expansion joint sealing in Colchester

Our movement joint work takes in walls, panels, decks and floors: vertical joints in brick and block facades, joints between precast or cladding panels, concrete slab and deck joints, ramps, podiums and internal floors. The product depends on the movement, the weather and anything that runs over it. The enquiries we see most involve spalled or broken joint edges in floors and decks and joints packed with grit and debris, on blockwork control joints, brickwork movement joints and cladding panel joints. Facilities teams, main contractors and managing agents in Colchester tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Industrial estates, retail parks and multi-storey car parks are typical of a place the size of Colchester. Their floor joints take forklifts, pallet trucks and cars every day, and the right filler or sealant depends on the traffic and the movement.

Work we carry out comes with a 12-month guarantee. If an installation problem shows up, call 01277 525 020 or send photos by email and we will arrange a return visit.

When to call us in Colchester

Weathering wears down sealant on exposed elevations and decks. UV hardens the surface, and the sealant loses its ability to stretch and opens at the next temperature swing.

Clients usually get in touch after noticing something like this:

  • Rain penetration at brick or block movement joints
  • Spalled or broken joint edges in floors and decks
  • Hardened, cracked sealant on exposed facades
  • Debris jammed in movement joints

For an estate such as Oaks Hospital (1.1 miles north of Colchester), the joints in ramps, decks and long building elevations all need attention over time.

Before you book anyone

  • Who will actually carry out the work
  • What site paperwork they can supply
  • The terms of the workmanship guarantee
  • Their pre-qualification and accreditations

Questions to ask before you appoint anyone

What we can’t put right

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
  • Changing the joint layout or spacing of a structure
  • Waterproofing layers buried beneath the sealant

If you’re not sure, just ring 01277 525 020 or send details through our quote form and we’ll give you a straight answer before you book.

What we seal

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

Common questions from Colchester clients

Will our site in Colchester have to close for joint sealing?

In most cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. We agree the sequence and timings with you before we start.

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

Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Can you seal joints in cold or wet weather?

Outside work depends on conditions because a damp or frozen joint won’t take a proper bond. Internal floor joints are far less affected.

What site paperwork can you supply?

Each site asks for different documents, so tell us what you need and we will confirm it when we quote.

How do I request a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.

Why do our movement joints keep failing?

The way it has failed typically tells us why: a split through the middle points to over-stretching, while peeling from one face points to preparation or primer. Sometimes the edge material itself has failed.

Do you guarantee expansion joint work?

Our workmanship on movement joints carries a 12-month guarantee. Damage from later works or traffic loads outside the joint’s design isn’t a workmanship fault.

Cost factors for movement joints

To price the job, we consider:

  • The total length or number of joints
  • Travel to remote or island sites
  • Access and working height
  • Specialist products, such as fire-rated or hygienic sealants

The price depends on how many linear metres there are, what has to come out first and the access. Call for a fixed quote once you have the details.

Details that help us quote

For an accurate fixed quote, we need a clear picture of the site. Useful things to include:

  • The type of building and who uses it
  • Asbestos survey details if the building is older
  • Specification clauses that apply
  • Rough lengths or quantities, or drawings if you have them

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, speak to us on 01277 525 020 or email a schedule or drawings.

What happens if it’s left?

A torn seal left alone usually gets worse. Water and debris get in, the joint jams and the edges spall. Acting at the first split keeps the cost down. A leaking joint in a commercial building in Colchester can damage stock, ceilings and finishes, and putting that right typically costs more than the reseal. It’s worth fixing at the first sign.

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Slabs, ramps and loading bays in Colchester

The South East is one of the drier parts of the UK. External joints still wait for dry conditions, and where de-icing salt is spread in winter, open joints let it in. The 3 miles around Colchester 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.

Schools like Colchester Sixth Form College often have long brick elevations with movement joints that age quietly. Across sites such as Cowdray Trade Park, 0.6 miles to the north of Colchester, floor and movement joints can be sealed in phases so units keep working.

Colchester is in Essex. Across the CO4 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Colchester is one of 644 places in Essex on our list for movement joints. We also cover London, some 50 miles away.

Business premises anywhere in CO4, CO3, CO2 and CO1 are within our area for movement joints. For a building on High Street, North Station Road and Durham Square or nearby, send details and we will quote for movement joints. Colchester sits on or close to the A12 and A120, useful when we plan access and materials. Just outside Colchester, we also work in Camulodunum (1 mile west), Braiswick (1 mile west), Abbey Field (1 mile south), Lexden (1 mile west) and Beacon End (3 miles west). Nearby towns on our patch include Braintree (14 miles west), Clacton-on-Sea (12 miles south-east), Maldon (15 miles south-west), Witham (13 miles south-west), Halstead (12 miles west) and Heybridge (14 miles south-west).

How a job runs

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Town-centre jobs in Colchester can mean limited parking and loading, while out-of-town estates typically have yards and car parks. Either way, tell us what’s available.

  1. We look at the joints, their width and how they’ve failed.
  2. A fixed quote follows, naming the sealant and its movement class.
  3. Old sealant and filler are cut out and the joint faces cleaned back to sound material, and we tell you if any edges need repairing first.
  4. We control the depth with backing rod or, in shallow joints, bond-breaker tape.
  5. Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
  6. Finished joints are checked and backed by our 12-month guarantee.

Preparing the site

  • Send your site hours and access windows
  • For older buildings, check the asbestos register before work
  • Explain the parking and delivery arrangements
