Expansion joint sealing in Pollards Hill

Floor movement joints in warehouses, retail and public buildings carry wheeled traffic. Unsupported edges break up under wheels. We’ll tell you if the edges need repairing before sealing and phasing can keep areas working. We work on precast concrete panel joints, blockwork control joints and brickwork movement joints, and what we are called in for most is debris jammed in movement joints and sealant pulling off the joint face. A specialist sealant contractor works differently from a general builder: in Pollards Hill, that means joint design, primers and backing rod as standard.

Areas such as a loading bay or car park deck in Pollards Hill usually have to stay in use. Joints are done in sections, with bays coned off one after another, so the site keeps operating, at times agreed with the building manager.

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

Slabs, ramps and loading bays in Pollards Hill

London car parks, loading bays and podium decks often can’t close for long, so we seal in sections and hand areas back as each cures. Pollards Hill has at least three named business or industrial parks inside a 3-mile radius. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.

For an estate such as British Home & Hospital for Incurables (1 mile north of Pollards Hill), the joints in ramps, decks and long building elevations all need attention over time. University campuses such as King's College London (4.2 miles north of Pollards Hill) have car parks, paved walkways and building elevations with movement joints.

Pollards Hill is about 1 mile north of Thornton Heath, in Greater London. We send applicators to Pollards Hill for movement joints. 764 places across Greater London fall within our area, Pollards Hill among them. We also cover London, around 6 miles from Pollards Hill.

Postcode districts covered here: CR7, SW16 and SE19 for movement joints. We cover commercial and managed buildings on Green Lane, Croft Road and Downs Road. If your building is just outside Pollards Hill, we cover Norbury (1 mile north), Thornton Heath (1 mile south), Streatham (2 miles north-west), Streatham Park (2 miles north-west) and Mitcham (2 miles west). Further afield, our area takes in London (6 miles north), City of Westminster (8 miles north), Marylebone (8 miles north), Kensington (7 miles north-west), St Pancras (8 miles north) and Shoreditch (8 miles north).

Looking after the joints

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:

  • Act on the first tear or lifting edge rather than waiting
  • Put movement joints on the planned maintenance inspection round
  • Look over external and deck joints after a hard winter
  • Sweep decks, ramps and floors so grit doesn’t collect in the joints

Add every elevation, deck and floor joint to your inspection round. Early splits and edges starting to lift show up on a routine check. Should you spot a problem, you can give us a call on 01277 525 020 or email the details over and send a picture.

Floor joints with failed fillers break up quickly under wheels. Broken arrises jolt trucks, loads and drivers. Sealing early protects the edges.

Your questions answered

Do you take on work at healthcare sites like British Home & Hospital for Incurables?

Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.

Will you take on work at estates like Thornton Road Industrial Estate, close to Pollards Hill?

Yes. Our area takes in Pollards Hill and its surroundings, with estates and business parks such as Thornton Road Industrial Estate included. Send details of the unit and the work through our quote form for a quick quote.

How long do sealant joints last?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

Can a joint be sealed if the edges are broken?

The edges have to be sound. If they’re damaged, we’ll say so before any sealing.

When can you be on site?

We are in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.

Can you work on car park ramps and decks?

Yes. These joints take wheels, salt and water, so product choice matters, and we will tell you if any edges need repairing first.

Can staff carry on working while you’re here?

Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.

Do you need expansion joint sealing in Pollards Hill?

Three-sided adhesion is a common cause of early failure. Bonded on three faces, it can’t stretch evenly when the joint opens, which is why depth control matters.

If one of these sounds familiar, it’s time for a closer look:

  • Leaks through car park deck joints onto the level below
  • Expansion joints filled with dirt and stones
  • Previous reseals laid over old sealant
  • Brittle, chalky sealant on external joints

For a centre such as Whitgift Centre (2.3 miles south of Pollards Hill), the service yard and car park joints normally need attention first.

Questions to ask before you appoint anyone

When something else is needed

Honesty saves time and money. New sealant won’t cure:

  • Joints too narrow for the movement, which need redesigning by the engineer
  • Damaged metal nosings or cover plates over a joint
  • Concrete or masonry repairs along the arrises

If you are not sure, just call the office on 01277 525 020 or email the details over and we’ll give you a straight answer before you book.

Surfaces we seal

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

Our process

The first thing on site is a walk round with your contact, 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. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.

  1. We start with photos, approximate lengths and any drawings, visiting where needed.
  2. We compare each joint’s width with the movement and the sealant’s capability, and flag anything that needs an engineer.
  3. Old sealant and debris are cut out of every joint.
  4. Edges are checked, and we tell you if any need repairing before sealing.
  5. The right sealant goes in at the right depth, bonded to the two sides only.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

What we need from you

  • Move anything stored against the joints
  • For older buildings, check the asbestos register before work
  • Warn occupants and staff about the work

Advice

Leave it or put it right?

A torn seal left alone normally gets worse. Water and debris get in, the joint jams and the edges spall. Resealing early keeps the work to sealant. In a London building, a failed joint rarely affects only one party: water travels through shared structures, and a small leak becomes a dispute between occupiers. Dealing with it early is simpler for everyone.

A quote for movement joints depends on how many there are, their condition and the access, plus any specification you are working to. Call for a quote.
