Expansion joint sealing for commercial buildings in Old Heath

Floor movement joints in warehouses, retail and public buildings carry wheeled traffic. Unsupported edges break up under wheels so the product has to suit both the traffic and the movement. If the arrises are already broken, we will say so before sealing, and phased work keeps areas in use. If you’re dealing with torn sealant in brick or block movement joints and expansion joints filled with dirt and stones, we can put it right, on podiums and floor movement joints, cladding panel joints and precast concrete panel joints alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Old Heath, that means joint design, primers and backing rod as standard.

Small units near places like Old Heath are often converted farm buildings with new concrete floors. Saw-cut and construction joints in those floors need the right filler or sealant for the forklifts and trolleys that use them.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Different surfaces, different methods

Cladding panel joints

Cladding panels move more than masonry as they heat and cool. A sealant with the right movement class is chosen in a colour confirmed for that product.

Internal floor movement joints

Forklift and pallet-truck wheels break unsupported joint edges. We match the product to the traffic and the movement flagging broken arrises before sealing.

Diagnose, treat, sign off

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Several jobs near Old Heath can be grouped on one trip. Tell us your site hours and we will plan around them.

  1. First the joints are inspected, widths measured and the type of failure noted.
  2. You receive a fixed quote stating the product and the movement it is rated for.
  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. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
  6. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

What we need from you

  • Confirm the product named in the specification
  • Move anything stored against the joints
  • Agree which areas must stay open

Request a quote

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

Aftercare for building managers

To get the most from the new sealant:

  • Keep stones and debris out of open joint lines
  • Report split or peeling joint sealant early
  • Reopen bays and walkways only after the stated cure time
  • Record the sealant used and the date in the O&M file

Floor joints on main traffic routes need watching more closely than the rest. Avoid standing heavy loads or racking legs on the joints.

External wall joints that fail let rain into the masonry and cavity. It can surface inside as damp a long way from the joint. Resealing promptly prevents internal damage.

FAQs: Old Heath

Does your area include sites such as Grange Way Business Park, near Old Heath?

Yes. Our area takes in Old Heath and its surroundings, with estates and business parks such as Grange Way Business Park included. To start, just ring 01277 525 020 or send photos by email with the unit, the joints involved and your access times.

Is a hospital such as Oaks Hospital somewhere you can work?

Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.

Are you fully insured?

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

Can you work while the building is occupied?

Usually, yes. Phased work can be planned so areas stay in use.

How do I request a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.

Does weather matter for sealant work?

Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Does the weather affect joint sealing?

Sealing onto a damp surface leads to adhesion failure so we’d rather rearrange than seal in the rain. We agree a revised date with you.

When to call us in Old Heath

Some joints were never sealed with the right product. A stiff or general-purpose sealant across a joint with large movement won’t cope. BS EN ISO 11600 classifies building sealants by movement capability.

Most enquiries start with something like this:

  • Debris jammed in movement joints
  • Damp inside where a wall movement joint has failed
  • Water dripping through deck or ramp joints
  • Hardened, cracked sealant on exposed facades

For buildings at a park such as Grange Way Business Park, under half a mile to the north-east of Old Heath, brick and panel movement joints are easy to forget until one leaks.

Before you book anyone

  • Proof of insurance
  • How the joint faces will be prepared and primed
  • Whether old or failed sealant will be cut out, not overlaid
  • Their approach to joint depth and backing

How to choose a sealant contractor

Work for main contractors and building owners

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

Expansion joint sealing around Old Heath: how the place shapes the job

Old Heath sits close to the coast, within about 3 miles. Open joints in coastal car parks and yards let in salt-laden water as well as grit, so a failed joint lets more in and the edges break up sooner. Rainfall across the South East, Old Heath included, is lower than in many parts of the UK. External slab and deck joints still need a dry, clean joint to seal, and winter de-icing salt on car parks and ramps works into any open joint.

Sites like Oaks Hospital (to the north-west of Old Heath) carry ambulances, deliveries and visitors’ cars over their road and deck joints. University campuses such as University of Essex, 0.9 miles north-east of Old Heath, have car parks, paved walkways and building elevations with movement joints.

Old Heath is about 1 mile south of Greenstead, in Essex. Across the CO2 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Our Essex coverage takes in 644 places. We also cover London, around 51 miles from Old Heath.

When it isn’t the sealant

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Concrete or masonry repairs along the arrises
  • Waterproofing layers buried beneath the sealant
  • Cracking or settlement that calls for an engineer’s assessment

If you are not sure, just ring 01277 525 020 or email us and we will give you a straight answer.
