Expansion joint sealing for Kent Street sites

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

Expansion joint sealing for commercial buildings in Kent Street

Our movement joint work takes in walls, panels, decks and floors: vertical joints in brick and block facades, joints between precast or cladding panels, concrete slab and deck joints, ramps, podiums and internal floors. Every one calls for a sealant picked for its movement, exposure and traffic. Most enquiries involve weathered movement joint sealant that no longer flexes and expansion joints filled with dirt and stones, on blockwork control joints, car park decks and ramps and cladding panel joints. For commercial sealant work in Kent Street, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Halls, schools and small commercial buildings near places like Kent Street have movement joints in brick, block and concrete too. They’re easily forgotten until water gets in or an edge breaks.

Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

From enquiry to sign-off

Site rules come first: signing in, inductions and any permit to work. Once we’re cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Jobs in and around smaller places like Kent Street are typically planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.

  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 and tell you if the design looks wrong for the movement.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  4. Any broken arrises or friable edges are flagged before work goes further.
  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.

Getting the site ready

  • Explain the parking and delivery arrangements
  • Tell staff and tenants when we will be in
  • Share the asbestos register for older buildings

How the job changes by surface

Podium joints

On podiums, the joint can belong to a larger waterproofing detail. We reseal the joint where sealant is the specified fix, and tell you if the problem looks like the waterproofing below.

Internal floor movement joints

Wheeled traffic chips floor joint edges that aren’t supported. We match the product to the traffic and the movement.

What sets the cost

To price the job, we consider:

  • The site’s rules and procedures
  • Access and working height
  • Which sealant the job calls for
  • Travel to remote or island sites

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.

Before you send an enquiry

The more we know, the firmer the quote. When you get in touch, include:

  • Drawings or a marked-up plan, if available
  • Whether the building will be occupied during the work
  • Clear photos of the problem areas
  • Specification clauses that apply

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. The easiest way is to call 01277 525 020 or email us.

After the work

Keep the joints in good shape with a few simple steps:

  • Keep scrapers and ploughs from dragging across joint sealant
  • Reopen bays and walkways only after the stated cure time
  • Act on the first tear or lifting edge rather than waiting
  • Note which joints were done, when, and with what

Movement joints belong on the planned maintenance inspection list. A periodic look picks up tears and lifting before water gets in. If anything looks wrong, call 01277 525 020 or email drawings and photos with photographs.

Floor joints with failed fillers break up quickly under wheels. Damaged edges make the floor rough and wear wheels faster, and the damage spreads along the joint. Keeping the filler or sealant sound protects the floor.

FAQs: Kent Street

Will you take on work at estates like Oakendene Industrial Estate, close to Kent Street?

Yes. We cover Kent Street and the area around it, including industrial estates, business parks and retail parks such as Oakendene Industrial Estate. A few photographs and the unit address let us price the work.

Is Kent Street too small for you to travel to?

Not at all. Kent Street is within our area. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

What do you charge?

There isn’t a price list, as every site differs. Send photos or drawings and we’ll price it at a fixed figure.

How do I request a quote?

The quote form is the simplest route, though you can also call the office on 01277 525 020 or email drawings and photos. Photos, drawings or a joint schedule help us quote quickly.

Can you work on car park ramps and decks?

Yes. These joints take wheels, salt and water, so product choice matters.

What guarantee do you give on joint sealing?

The workmanship is guaranteed for 12 months from sign-off and we hold public liability insurance. Regular sweeping and inspection help the joints last.

Do you take on small jobs?

Small jobs are welcome alongside larger packages. Send details for a fixed quote.

General trades versus a specialist

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Common problems we fix in Kent Street

Three-sided adhesion is a common cause of early failure. Sealant fixed to the base and sides can’t flex, so it tears so backing is set before sealing.

Site and facilities staff are often the first to spot these:

  • Expansion joints split through the centre of the bead
  • Water dripping through deck or ramp joints
  • Arrises breaking up along floor joints
  • Joints where the bead has lost adhesion

Warehouse floors on estates like Oakendene Industrial Estate, 0.8 miles north of Kent Street, carry pallet trucks and forklifts over every saw-cut joint.

Before you book anyone

  • Whether old or failed sealant will be cut out, not overlaid
  • Who will actually carry out the work
  • How long is the guarantee, and what does it include?
  • Is the sealant right for the movement and the substrate?
