Expansion joint sealing for Maldon sites

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

Doing it in-house

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

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.

About our expansion joint sealing in Maldon

We cover the full range of movement joints: vertical joints in brick and block facades, joints between precast or cladding panels, concrete slab and deck joints, ramps, podiums and internal floors. The product depends on the movement, the weather and anything that runs over it and we name it in the quote. If you have damp inside where a wall movement joint has failed and brittle, chalky sealant on external joints, we can put it right, whatever the surface. Looking for mastic applicators who cover Maldon? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

Joints in town car parks and service yards take tyres, de-icing salt and standing water. Catching a joint before its edges break is the simpler route.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Questions we’re asked in Maldon

Will you take on work at estates like Riverside Industrial Estate, close to Maldon?

Yes, sites like Riverside Industrial Estate are within our area, along with the rest of Maldon. Send details of the unit and the work through our quote form for a quick quote.

Do you take on work at healthcare sites like St Peter's Hospital?

Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.

Can one quote cover more than one building?

Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.

Is Maldon in your area?

Yes. Maldon is in our area and the rest of Essex. For a quote, speak to us on 01277 525 020 or send photos by email.

What hours do you work?

Give us your site hours and any access windows in your enquiry, and we’ll schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.

How long does movement joint sealing take?

The metres of joint, the access and the amount of removal decide it. Typically it takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing.

Do you need to see the site first?

It depends on the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.

From enquiry to sign-off

In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before the next one starts. Most work in Maldon is one building at a time: a school, a unit, an office or a block. We start with your photographs, drawings or a site visit, then send a fixed quote.

  1. We assess the joints on site or from photos, noting widths and how each has failed.
  2. A fixed quote names the sealant we propose and its movement class.
  3. Where areas have to stay open, we agree a phased sequence before starting.
  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. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

Before we start on site

  • Tell us your opening times and when work is allowed
  • Make sure the joints can be reached
  • Share the asbestos register for older buildings

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.

Slabs, ramps and loading bays in Maldon

Maldon lies within about 1 mile of the sea. Open joints in coastal car parks and yards let in salt-laden water as well as grit, so it pays to keep them sealed. Maldon lies roughly 37 miles out from central London. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital.

On industrial estates such as Riverside Industrial Estate, which lies north of Maldon, saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic. Hospitals like St Peter's Hospital (to the west of Maldon) have multi-storey or surface car parks whose joints carry vehicles round the clock. Another example is Blackwater Retail Park, 0.6 miles to the north of Maldon, where floors and yards would be done in stages around the occupiers.

Maldon is about 15 miles south-west of Colchester, in Essex. We send applicators to Maldon for movement joints. Our Essex coverage takes in 644 places, large and small. For work in that direction, see our London page (37 miles or so).

Business premises anywhere in CM9, CM3, CM0 and CM8 are within our area for movement joints. Buildings on High Street, Market Hill and Brooke Square are within our area for movement joints. Maldon sits on or close to the A414 and B1010. Just outside Maldon, we also work in Heybridge (1 mile north), Langford (2 miles north-west), Curling Tye Green (2 miles west), Broad Street Green (2 miles north) and Hazeleigh (3 miles south-west). Nearby towns on our patch include Colchester (15 miles north-east), Chelmsford (8 miles west), Basildon (14 miles south-west), Braintree (12 miles north-west), Canvey Island (15 miles south) and Billericay (13 miles south-west). Maldon is one of the busier places in Essex, and we take on movement joints for its commercial and public buildings.

What the job involves on each surface

Car park decks and ramps

Car park joints are some of the hardest-working joints in any building. We use a sealant made for wheel loads and the expected movement.

Concrete and precast panel joints

Precast and concrete panel joints move daily. We use a sealant classed for the movement, laid over backing to depth.

When it isn’t the sealant

Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is one of these:

  • Proprietary pre-formed expansion joint systems
  • Broken or spalled joint edges, which need repairing before any sealant goes in
  • Joints too narrow for the movement, which need redesigning by the engineer

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

Surfaces we seal

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

Building owners, agents and FMs in Maldon

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Maldon can form part of a wider programme across Essex.

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.

Cost factors for movement joints

Each job is priced on its own details. The things that drive the figure:

  • Whether old sealant has to be cut out first
  • Access and working height
  • Induction, permit and paperwork requirements
  • Backing rod, priming and other preparation

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Before you send an enquiry

To price the job accurately, we need a clear picture of the site. Send us:

  • A wide shot and a close-up of the area
  • Drawings or a marked-up plan, if available
  • Access details, including height
  • What the building is and how it’s used

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.
