Expansion joint sealing in Thorington Street

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

What we can’t put right

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
  • Structural movement beyond what the joints were designed for (that needs a structural engineer)
  • Leaks coming from the membrane rather than the joint seal

Not sure which it is? You can call 01277 525 020 or send photos by email and we’ll tell you honestly before you book.

What we seal

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

Expansion joint sealing in Thorington Street, done properly

Width, depth and product all have to work together. Joint width must suit the movement and the movement class of the sealant. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises. We work on car park decks and ramps, brickwork movement joints and cladding panel joints, and what we are called in for most is layers of sealant in a movement joint and arrises breaking up along floor joints. Most enquiries from Thorington Street start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

In and around smaller places like Thorington Street, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Cost factors for movement joints

Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:

  • How accessible the joints are
  • Specialist products, such as fire-rated or hygienic sealants
  • The total length or number of joints
  • Whether the work must be split into stages

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Before you send an enquiry

Good information means a firmer quote. When you get in touch, include:

  • What the building is and how it’s used
  • Any specification or named product
  • Photos of the joints, close up and from further back
  • Approximate linear metres or a joint schedule

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, call the office on 01277 525 020 or use the quote form.

Traffic, movement and joints around Thorington Street

Thorington Street sits in one of the drier corners of the country, the South East. Outside joints in yards and car parks still have to be dry before sealing, and gritting in cold spells finds its way into open joints. Thorington Street is about 55 miles from central London. Warehousing clusters around the motorways that ring and radiate from London; their floors carry heavy traffic every shift.

Office parks like Langham Barns Business Centre (2.8 miles south of Thorington Street) have decks, ramps and clad elevations whose joints take movement every day.

Thorington Street is about 6 miles north of Colchester, in Essex. We cover Thorington Street and the rest of Essex, with the same fixed quotes and 12-month guarantee as everywhere else. Thorington Street is one of 644 places we cover in Essex. There’s a separate page for London, about 55 miles away.

Signs you need expansion joint sealing in Thorington Street

Sun, rain and frost age external movement joints. UV hardens the surface, and the sealant loses its ability to stretch, so it can’t follow the movement any more.

Common reasons buildings call us in:

  • Sealant peeling off one face of the joint
  • Torn sealant in brick or block movement joints
  • Arrises breaking up along floor joints
  • Previous reseals laid over old sealant

Hospital campuses such as Severalls Hospital (to the south of Thorington Street) grow in stages, leaving movement joints wherever new blocks meet old.

Before you book anyone

  • The named product and why it was chosen
  • What level of public liability insurance do they hold?
  • Who will actually carry out the work
  • How the existing material will be dealt with

Our contractor checklist

Questions we are asked in Thorington Street

Is Langham Barns Business Centre, near Thorington Street, within your area?

Yes. Our area takes in Thorington Street and its surroundings, with estates and business parks such as Langham Barns Business Centre included. Send details of the unit and the work through our quote form for a quick quote.

Can you work on a hospital site such as Severalls Hospital?

Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.

What’s the difference between an expansion joint and a movement joint?

Put simply, it’s a planned break in a wall, slab or deck so the materials can move. Many people call it an expansion joint.

When can you be on site?

We are in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.

Can weather delay the job?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

Do you work in Thorington Street?

Yes. Sites across Thorington Street are covered, and the same phone number covers every area.

How much does the work cost?

That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote.

Should maintenance staff do it?

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

What happens if it’s left?

A torn seal left alone normally gets worse. Grit and water fill the gap and the material either side breaks up, so a reseal turns into an edge repair as well. Resealing early keeps the work to sealant. For buildings around smaller places like Thorington Street, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote when you are ready.

Diagnose, treat, sign off

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself usually takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access, and our waste is bagged and taken away as we go. For work around Thorington Street, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  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. We strip out the old seal and prepare the faces, and we tell you if any edges need repairing first.
  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. Finished joints are checked and backed by our 12-month guarantee.

Getting the site ready

  • Tell staff and tenants when we’ll be in
  • For older buildings, check the asbestos register before work
  • Send any specification or drawings in advance
