Expansion joint sealing for Redbridge sites

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

When it isn’t the sealant

Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:

  • Changing the joint layout or spacing of a structure
  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)

If in doubt, ring 01277 525 020 or email the details over and we will say what we think.

Surfaces we seal

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

Expansion joint sealing for commercial buildings in Redbridge

Long runs of brick or block have movement joints built in, and they’re easy to miss until the sealant fails. Failed sealant here lets rain into the wall and can leave the joint full of debris. The old seal is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled, primed where the manufacturer specifies. We work on precast concrete panel joints, podiums and floor movement joints and car park decks and ramps, and what we are called in for most is expansion joints filled with dirt and stones and sealant peeling off one face of the joint. A specialist sealant contractor works differently from a general builder: on jobs in Redbridge, preparation and product choice get the time they need.

For a site near Redbridge, measurements and photos up front mean one trip where possible. Tell us the joint widths if you can, and what drives or walks over them.

We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

General trades versus a specialist

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

How the quote is worked out

Your fixed quote is built from the real scope. It allows for:

  • The size and state of each joint
  • Site requirements such as inductions and permits
  • Phasing around occupants
  • Removal of failed or old sealant

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Sending details for a quote

A good diagnosis starts with the right details. Let us know:

  • Rough lengths or quantities, or drawings if you have them
  • Anything awkward about access or site hours
  • Asbestos survey details if the building is older
  • Clear photographs of the problem areas

Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to phone 01277 525 020 or use the quote form with what you know.

Redbridge: questions and answers

Does the sea air around Redbridge change the choice of sealant?

It can. Coastal exposure works external joints harder than inland weather. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.

Is a hospital such as Western Community 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.

Can you seal joints in cold or wet weather?

Sealant needs a dry joint and a temperature within the product’s range. Cold, damp or frosty mornings can stop work outside, so we plan with the forecast in mind.

Is it fine to apply new sealant on top of old?

No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

How long will the new sealant last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

What hours do you work?

Give us your site hours and any access windows in your enquiry, and we will schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.

Are you insured?

Yes. We’re fully insured, and the certificate can go with your quote.

When to call us in Redbridge

Repeated failure often traces back to the wrong 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, and specifications often refer to it.

Most enquiries start with one or more of the following:

  • Joints packed with grit and debris
  • Spalled or broken joint edges in floors and decks
  • Damp inside where a wall movement joint has failed
  • Expansion joints split through the centre of the bead

Schools like Redbridge Primary School often have long brick elevations with movement joints that age quietly.

Questions to ask before you book

  • Will CSCS-carded applicators be on site?
  • Health and safety accreditation such as CHAS
  • How joint depth will be controlled
  • How the joint faces will be prepared and primed

Choosing a commercial sealant contractor

Floors, slabs and movement joints in Redbridge

The sea is no more than about 1 mile from Redbridge. Near the sea, external slabs, ramps and decks see salt air and driven rain as well as their usual loads, so a failed joint lets more in and the edges break up sooner. Redbridge has at least three named business or industrial parks inside a 3-mile radius. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic.

Large sites such as Western Community Hospital, 1.2 miles east of Redbridge, have car parks, service roads and long elevations with movement joints in brick and panels. If you manage units on an estate such as Manor Park Industrial Estate, less than half a mile to the west of Redbridge, the floor joints under forklifts and pallet trucks and the slab joints in the yard are the ones to watch.

Redbridge is about 1 mile east of Totton, in Southampton. Across the SO40 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. 30 places across Southampton fall within our area, Redbridge among them.

We cover the SO40, SO16 and SO15 postcode districts for movement joints. If your site is on Mill Road, Test Lane and Tate Road or close by, send details and we’ll quote for movement joints.

Nearby places we also cover include Eling (1 mile south-west), Millbrook (1 mile east), Hillyfields (1 mile north), Maybush (1 mile north-east) and Regents Park (1 mile east) for movement joints. A short drive away, we cover Southampton (3 miles east), Midanbury (5 miles east), Thornhill (6 miles east), Harefield (6 miles east), Itchen (5 miles east) and Sholing (5 miles east).

On site: what to expect

On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work usually takes a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints. Smaller jobs around Redbridge can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.

  1. First the joints are inspected, widths measured and the type of failure noted.
  2. A fixed quote names the sealant we propose and its movement class.
  3. Phasing is agreed so decks, floors or entrances can stay in use where needed.
  4. The failed seal is cut out and both joint faces cleaned back to sound material.
  5. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
  6. We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.

Before we start on site

  • Arrange parking or a loading space
  • Send asbestos survey details if the building is pre-2000
  • Move anything stored against the joints

Advice

Different surfaces, different methods

Concrete and precast panel joints

Concrete edges can be weak or carry release agents that stop adhesion. We prepare the faces thoroughly and prime where the maker calls for it, so the new seal holds.

Internal floor movement joints

Warehouse and retail floors have saw-cut induced joints and construction joints. A semi-rigid filler is common in trafficked industrial floors and a flexible sealant where the joint moves more.
