Need expansion joint sealing in The Common?

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

Honest limits

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • Movement on a scale no sealant is meant to absorb
  • Proprietary pre-formed expansion joint systems
  • Changing the joint layout or spacing of a structure

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

What we seal

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

How we handle expansion joint sealing in The Common

A movement joint only works while its seal does. When the sealant splits or lets go, the gap fills with dirt and water, the joint can’t close properly and its edges begin to crumble. Dealt with early, it stays a sealant job rather than a concrete or masonry repair. We work on car park decks and ramps, brickwork movement joints and podiums and floor movement joints, and the usual reasons a site gets in touch are debris jammed in movement joints and joints where the bead has lost adhesion. A single leaking joint is often how a building in The Common first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Smaller community and commercial buildings around The Common have their own movement joints in walls and floors. They tend to be overlooked until something leaks or cracks.

We stand by our work: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

The Common: questions and answers

Is The Common too small for you to travel to?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.

Can you take on a job at a hospital such as Saffron Walden Community Hospital?

Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

What timescale should we allow for resealing expansion joints?

Expect a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints and phased work can stretch that to suit your site. Cure time before reopening is confirmed on the day.

Are expansion joints and movement joints the same thing?

It’s a deliberate gap that lets the structure move without cracking. Expansion joint is a name often used for the same thing, and either way it needs a sound seal.

Will your applicators have CSCS cards?

Yes. Should the site need card details in advance, let us know and we will send them with the quote.

What do you charge?

There isn’t a price list, because every site is different. With photographs or drawings, we can give you a fixed quote.

Is movement joint sealing guaranteed?

Each job is backed by a 12-month guarantee on the workmanship. Damage from later works or traffic loads outside the joint’s design isn’t a workmanship fault.

Expansion joint sealing around The Common: points for this area

The Common lies roughly 41 miles out from central London. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital. The Common sits in one of the drier corners of the country, the South East. External joints still wait for dry conditions, and gritting in cold spells finds its way into open joints.

Schools like Radwinter Church of England Voluntary Aided Primary School often have long brick elevations with movement joints that age quietly.

The Common is about 4 miles east of Saffron Walden, in Essex. We cover The Common and the rest of Essex, with the same fixed quotes and 12-month guarantee as everywhere else. Across Essex, 644 places are covered, The Common among them. We also cover London, around 41 miles from The Common.

If you need expansion joint sealing in CB10, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. We also cover Radwinter (1 mile south), Maple End (1 mile south-west), Wimbish (2 miles south-west), Hempstead (2 miles east) and Church End (3 miles north-west) for movement joints. Nearby towns on our patch include Braintree (13 miles south-east), Saffron Walden (4 miles west), Halstead (14 miles south-east), Great Dunmow (10 miles south), Stansted Mountfitchet (10 miles south-west) and Great Notley (14 miles south-east).

Local landmarks in The Common

Diagnose, treat, sign off

When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, with the work itself usually taking a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing. If others near The Common need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. First, the joints are inspected for width, movement and the type of failure.
  2. A fixed quote follows, naming the sealant and its movement class.
  3. The failed seal is removed and both faces are cleaned until sound and dry.
  4. Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
  5. Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
  6. Each joint is inspected and handed over with our 12-month guarantee.

Signs you need expansion joint sealing in The Common

The edges of the material can fail rather than the sealant. If the edge of the joint is friable, the bond fails with it.

These are often picked up first by site or facilities staff:

  • Layers of sealant in a movement joint
  • Water dripping through deck or ramp joints
  • Joints packed with grit and debris
  • Torn sealant in brick or block movement joints

Sites like Saffron Walden Community Hospital, 3.5 miles to the west of The Common, carry ambulances, deliveries and visitors’ cars over their road and deck joints.

How to choose a sealant contractor

Cost factors for movement joints

These are the things that shape the price:

  • The product specified
  • The site’s rules and procedures
  • Travel to remote or island sites
  • Access and working height

The price depends on the quantity of joints, what has to come out first and the access. Call for a fixed quote when you are ready.

What we need to price the job

However big the job, these details speed things up:

  • The type of building and who uses it
  • Access details, including height
  • Your programme or deadline
  • Asbestos survey details if the building is older

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.

Looking after the joints

Problems stay small when the joints are checked regularly. In particular:

  • Inspect movement joints alongside other routine building checks
  • Inspect exposed joints once the cold weather has passed
  • Record the sealant used and the date in the O&M file
  • Report split or peeling joint sealant early

Keep wheels, feet and water off new joints until the sealant has cured. How long that takes depends on the product, the temperature and the depth of the joint. Keeping the area coned off until then avoids tyre marks and damage.

An open joint fills with grit, and a joint full of grit can’t close. The edges then take the pressure and start to spall. A sound seal keeps the joint working.

What happens if it’s left?

Spot repairs can be useful on a tight budget. But if the rest of the run is the same age and product, it’s normally not far behind and repeated access costs add up. We can price a patch and a full reseal side by side. One visit to deal with every failing joint makes more sense than several trips to a place like The Common. Photos of every joint help us quote for the whole job.

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we will explain how it’s made up.
