Expansion joint sealing in Harlow

Few joints take as much punishment as those in a car park. Wheel loads, grit and de-icing salts attack the seal and the concrete either side, so failed seals soon lead to leaks onto the level below and broken edges. We reseal deck and ramp joints with a trafficable sealant chosen for the movement, phasing bays so the car park can stay in use. If you’re dealing with debris jammed in movement joints and hardened, cracked sealant on exposed facades, we can help, on brickwork movement joints, podiums and floor movement joints and precast concrete panel joints alike. For commercial sealant work in Harlow, you deal with one contact from quote to sign-off, whether it’s one building or several.

Joints in town car parks and service yards take tyres, de-icing salt and standing water. Resealing before the edges break up is far less disruptive than repairing them later.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

When to bring in a specialist

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Traffic, movement and joints around Harlow

At about 21 miles from central London, Harlow is within reach of the capital. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital. Less than 3 miles from Harlow there are at least three named estates and business parks. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.

A healthcare site such as Princess Alexandra Hospital, 1.2 miles to the west of Harlow, depends on car parks, ramps and service yards whose joints take traffic all day. Business parks such as Harlow Innovation Park (0.8 miles north-east of Harlow) have car parks, paved areas and long brick and panel elevations, all with movement joints.

How the job changes by surface

Internal floor movement joints

Wheeled traffic chips floor joint edges that aren’t supported. The right filler or sealant for the traffic and movement protects them flagging broken arrises before sealing.

Cladding panel joints

Access to cladding joints is agreed before the price is fixed. Photos taken near the joints help us price accurately.

Our process

Working in a building that stays open takes some planning. We sign and contain the area we’re in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Parking and loading for town-centre jobs in Harlow are worth mentioning when you send details. On estates and business parks it’s typically simpler.

  1. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  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, flagging any broken edges that need repair before sealing.
  4. We control the depth with backing rod or, in shallow joints, bond-breaker tape.
  5. Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
  6. We check every joint before sign-off, and the work carries our 12-month guarantee.

What we need from you

  • Send asbestos survey details if the building is pre-2000
  • Let us know about inductions and permits
  • Arrange parking or a loading space

Advice

What we can’t put right

Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be one of these:

  • Crumbling edges that would give a new bead nothing sound to grip
  • Damaged metal nosings or cover plates over a joint
  • Movement on a scale no sealant is meant to absorb

Not sure which it is? You can call the office on 01277 525 020 or email a schedule or drawings and we’ll tell you honestly.

Your questions answered

Will you take on work at estates like Harlow Innovation Park, close to Harlow?

Yes. Estates, retail parks and business parks around Harlow, Harlow Innovation Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

Our unit in Harlow is decades old: is it worth resealing the floor joints?

Generally yes, provided the arrises are still in reasonable shape. We will advise on the product for your traffic and flag any edges that need repair first.

Do you work to architects’ specifications?

Yes. Send it with your enquiry, and we will price the work to it, flagging anything that needs clarifying.

Can one quote cover more than one building?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

Can the building stay open while you work?

In the majority of cases, yes. We phase the work so most of the building stays in use.

How do we ask for a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photographs and a postcode.

Do you cover Harlow?

Yes. We take on work across Harlow, and the same phone number covers every area.

What we are called out for in Harlow

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

Common reasons buildings call us in:

  • Joints packed with grit and debris
  • Spalled or broken joint edges in floors and decks
  • Previous reseals laid over old sealant
  • Damp inside where a wall movement joint has failed

At places like Bush Fair Shopping Centre, which lies south of Harlow, joints are sealed a section at a time so operations carry on.

What your quote should include

  • Will failed sealant be removed rather than covered?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • What site paperwork they can supply
  • Whether their applicators hold CSCS cards

How to choose a sealant contractor

Why act early in Harlow

Patching the worst lengths of a joint can make sense short term. But if the rest of the run is the same age and product, it’s typically not far behind and repeated access costs add up. Where it helps, we quote both options. For businesses and landlords in Harlow, a tidy, sound joint also matters for appearance. Renewing it keeps the building looking cared for.

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Why choose Mastic Doctor in Harlow

  • Over 20 years of commercial sealing
  • One number for every site we cover
  • Constructionline member for supplier checks
  • RAL and finish matching where the product range allows
