Expansion joint sealing in Broom Street, done properly

We’ve been sealing expansion and movement joints for over 20 years, for main contractors, FMs, managing agents and building owners. CHAS accredited, Constructionline member, CSCS-carded applicators and five million pounds of public liability insurance. Each job is backed by a 12-month guarantee on the workmanship. We work on precast concrete panel joints, blockwork control joints and car park decks and ramps, and what we are called in for most is water getting into the wall through a failed joint and chipped joint edges on forklift routes. A single leaking joint is often how a building in Broom Street first comes to us: we look at the rest while we are there and tell you what we find.

Smaller community and commercial buildings around Broom Street have their own movement joints in walls and floors. They tend to be overlooked until something leaks or cracks.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application.

What the job involves on each surface

Car park decks and ramps

Failed deck joints often show as leaks on the level below. We strip the old seal, prepare the edges and seal again, and we will tell you if any edges need repairing first.

Concrete and precast panel joints

Concrete edges can be weak or carry release agents that stop adhesion. Proper cleaning and primer where specified give a sound bond, so the new seal holds.

When it isn’t the sealant

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Cracking or settlement that calls for an engineer’s assessment
  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
  • Leaks coming from the membrane rather than the joint seal

If in doubt, call 01277 525 020 or email drawings and photos and we will say what we think.

Joints and surfaces we work on

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

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 easy to get wrong without experience.

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

Common questions from Broom Street clients

Can you work on a hospital site such as Whitstable and Tankerton 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.

Is Broom Street too small for you to travel to?

Not at all. Broom Street is within our area. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Do you work to architects’ specifications?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.

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

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

Can you fit around our working hours?

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

Which sealant will you use?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Can you handle several sites?

Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.

Traffic, movement and joints around Broom Street

The sea is no more than about 2 miles from Broom Street. Near the sea, external slabs, ramps and decks see salt air and driven rain as well as their usual loads, so it pays to keep them sealed. Rainfall across the South East, Broom Street 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.

On a site such as Waterham Business Park (2 miles east of Broom Street), the movement joints are in car park slabs, paving and building elevations. A healthcare site such as Whitstable and Tankerton Hospital (5.6 miles north-east of Broom Street) depends on car parks, ramps and service yards whose joints take traffic all day.

Quoting for work in Broom Street

To price the job, we consider:

  • Access and working height
  • Travel to remote or island sites
  • Removal of failed or old sealant
  • Phasing around occupants

What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote when you are ready.

Before you send an enquiry

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

  • Drawings or a marked-up plan, if available
  • Any dates the work must fit around
  • Photos of the joints, close up and from further back
  • The product your specification calls for

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. Smaller jobs need nothing more than photos and a few notes.

On site: what to expect

We begin with a short walk round with whoever looks after the building, 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. If others near Broom Street need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. We compare each joint’s width with the movement and the sealant’s capability.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  4. Edges are checked, and we tell you if any need repairing before sealing.
  5. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

Before we start on site

  • Confirm the product named in the specification
  • Tell us which areas need to stay in use
  • Send asbestos survey details if the building is pre-2000

Advice

When to call us in Broom Street

Sealant peeling cleanly off one side is an adhesion failure. Poor preparation, a skipped primer, or sealant bonded to the back of the joint are typical reasons.

Any of the following is a good reason to get the joints checked over:

  • Weathered movement joint sealant that no longer flexes
  • Debris jammed in movement joints
  • Layers of sealant in a movement joint
  • Car park joints leaking onto vehicles below

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

What to look for in a quote

  • Their pre-qualification and accreditations
  • Their approach to joint depth and backing
  • How long is the guarantee, and what does it include?
  • Can the work be phased to keep areas open?
