Expansion joint sealing in Lexden, done properly

We have been sealing expansion and movement joints for over 20 years for contractors, facilities managers and owners. Our applicators are CSCS-carded, we’re CHAS accredited and a Constructionline member, and we carry five million pounds of public liability insurance. Each job is backed by a 12-month guarantee on the workmanship. Most enquiries involve water getting into the wall through a failed joint and previous reseals laid over old sealant, across cladding panel joints, podiums and floor movement joints and blockwork control joints. One point of contact handles commercial sealant work in Lexden from the first photographs to the final walk-round, whether it’s one building or several.

Around places the size of Lexden, joints that need sealing tend to be in rural business units, farm buildings put to commercial use, schools and community buildings. Concrete floors and yards in these buildings move and crack like any others.

Work we carry out in Essex comes with a 12-month guarantee. If an installation problem shows up, speak to us on 01277 525 020 or send photos by email and we’ll arrange a return visit.

Common problems we fix in Lexden

Sun, rain and frost age external movement joints. UV hardens the surface, and the sealant loses its ability to stretch.

Common reasons buildings call us in:

  • Arrises breaking up along floor joints
  • Expansion joints split through the centre of the bead
  • Sealant peeling off one face of the joint
  • Leaks through car park deck joints onto the level below

Phasing is what makes joint work possible on busy sites such as Angora Business Park (1 mile south-west of Lexden): one bay, aisle or car park row at a time.

Questions to ask before you book

  • How joint depth will be controlled
  • Are they CHAS accredited or on Constructionline?
  • The terms of the workmanship guarantee
  • The named product and why it was chosen

Questions to ask before you appoint anyone

Questions we’re asked in Lexden

Can you work at a site such as Stanway Retail Park, by Lexden?

Yes, sites like Stanway Retail Park are within our area, along with the rest of Lexden. Photos and a short description are enough for a first look.

Is hospital work, at somewhere like Oaks Hospital, something you do?

Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Will you quote for a small job?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

Do you reseal car park expansion joints?

Yes. Tell us how the car park is used and which areas must stay open, and we will plan the phasing around it.

How do I request a quote?

There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photographs and a postcode.

Why has the sealant in our expansion joints split?

Adhesion failure, cohesive failure, edge breakdown and UV ageing account for most cases. Working out the cause comes first since each needs a different fix.

Is colour matching possible?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

What sealant work can’t fix

Some faults sit outside our scope, and we say so rather than covering them up:

  • Structural movement beyond what the joints were designed for (that needs a structural engineer)
  • Changing the joint layout or spacing of a structure
  • Waterproofing layers buried beneath the sealant

If you’re not sure, just phone 01277 525 020 or email us and we will give you a straight answer before you book.

What we seal

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

What sets the cost

Quotes vary with the job. Expect it to depend on:

  • Location, for remote and island sites
  • Site requirements such as inductions and permits
  • Phasing around occupants
  • Any access equipment needed

The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.

Sending details for a quote

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

  • Where the site is, with the postcode
  • How the joints are reached, and at what height
  • Approximate linear metres or a joint schedule
  • Photos of the joints, close up and from further back

A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or call the office on 01277 525 020 or email us if you’d rather talk the job through.

Warehouse floors and decks around Lexden

The South East is one of the drier parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, and gritting in cold spells finds its way into open joints. Central London is about 49 miles from Lexden. The South East has large numbers of industrial estates and warehouses along the motorway corridors.

University campuses such as University of Essex (3.4 miles east of Lexden) have car parks, paved walkways and building elevations with movement joints. Hospitals like Oaks Hospital (2 miles north-east of Lexden) have multi-storey or surface car parks whose joints carry vehicles round the clock.

Maintenance after handover

A few simple habits keep the new joints working:

  • Treat a small split as a warning, not a cosmetic issue
  • Include every elevation and deck joint in periodic inspections
  • Plan racking layouts so feet don’t land on a joint
  • Note which joints were done, when, and with what

Our workmanship on movement joints carries a 12-month guarantee. Keep the handover details, product and date with your O&M records.

Rain gets into walls through torn brick and block movement joints. The first sign is often a damp patch indoors by which time the joint has been open for a while. Catching it early keeps the water outside.

Our process

Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. Several jobs near Lexden can be grouped on one trip. Tell us your site hours and we’ll plan around them.

  1. First, the joints are inspected for width, movement and the type of failure.
  2. Next, we fix a price and confirm the sealant we propose for the movement.
  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. Each joint is inspected and handed over with our 12-month guarantee.

Preparing the site

  • Confirm the product named in the specification
  • Explain the parking and delivery arrangements
  • Clear stock, furniture or equipment away from the joints

Related advice

Site staff or a sealant specialist?

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
