Expansion joint sealing in Upper Hartfield

Floor movement joints in warehouses, retail and public buildings carry wheeled traffic. Without a sound filler, joint edges chip and spall under load so the product has to suit both the traffic and the movement. We will tell you if the edges need repairing before sealing and phasing can keep areas working. We work on blockwork control joints, precast concrete panel joints and cladding panel joints, and what we are called in for most is torn sealant in brick or block movement joints and debris jammed in movement joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Upper Hartfield it comes down to the same thing: the right product in a properly prepared joint.

In and around smaller places like Upper Hartfield, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Diagnose, treat, sign off

On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself usually taking a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints. For a building around Upper Hartfield, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  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.
  4. Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
  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.

Before we start on site

  • Tell us your opening times and when work is allowed
  • Point out parking and an unloading spot
  • Have the specification and drawings to hand

Why it’s worth doing now in Upper Hartfield

Resealing is typically the answer, not replacing the element. If the material either side is sound, a properly prepared reseal restores the joint. If the edges have broken up, we will tell you they need repairing first. Around Upper Hartfield, it’s better to renew all the failing joints at once. Send photos of each area and we’ll quote for the lot.

Pricing movement joints depends on how many there are, their condition and the access. Call for a quote.

Do you need expansion joint sealing in Upper Hartfield?

Sometimes the sealant holds but the substrate breaks away. If the edge of the joint is friable, the bond fails with it, so we tell you if the edges need repairing first.

Look out for the following:

  • Rain penetration at brick or block movement joints
  • Leaks through car park deck joints onto the level below
  • New sealant over old, now failing
  • Sealant peeling off one face of the joint

At places like Riverview Business Park, which lies west of Upper Hartfield, joints are sealed a section at a time so operations carry on.

What your quote should include

  • Their pre-qualification and accreditations
  • The terms of the workmanship guarantee
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Who will actually carry out the work

Questions to ask before you appoint anyone

What sets the cost

What shapes the price:

  • Quantities, in metres or numbers
  • Site requirements such as inductions and permits
  • Backing rod, priming and other preparation
  • Phasing around occupants

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.

Before you send an enquiry

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

  • The type of building and who uses it
  • Drawings or a marked-up plan, if available
  • Photos of the joints, close up and from further back
  • The asbestos register, for older buildings

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.

Surface by surface

Cladding panel joints

Access to cladding joints is agreed before the price is fixed. Close-up photographs help us judge the joints, or we visit if they don’t show enough.

Internal floor movement joints

Forklift and pallet-truck wheels break unsupported joint edges. The right filler or sealant for the traffic and movement protects them flagging broken arrises before sealing.

Upper Hartfield: questions and answers

Do you take on work at healthcare sites like Crowborough War Memorial 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.

Is Upper Hartfield too far out for you?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

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

It’s a deliberate gap that lets the structure move without cracking. Expansion joint is a name often used for the same thing and both need a flexible seal.

Can you work while the building is occupied?

Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.

Is movement joint sealing guaranteed?

It’s backed by our 12-month guarantee. Tell us straight away if a joint we sealed gives trouble in that time.

When can you be on site?

The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.

Can you quote from photos?

Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we will arrange a visit.
