Expansion joint sealing in Highams Park, done properly

Brickwork and blockwork walls have vertical movement joints at intervals that most people only notice when the sealant has gone. Once the seal fails, rain reaches the cavity and the joint can no longer close. 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 podiums and floor movement joints, blockwork control joints and brickwork movement joints, and the usual reasons a site gets in touch are hardened, cracked sealant on exposed facades and joints where the bead has lost adhesion. One point of contact handles commercial sealant work in Highams Park from the first photos to the final walk-round, for single jobs and planned programmes alike.

London’s floor joints are concentrated in warehouses and trade units, car parks, podiums and decks. Planning a job in Highams Park means thinking about access, loading times and the ULEZ as well as the joints.

The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Your questions answered

Do you take on jobs in Highams Park where loading and access are tightly controlled?

Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Send the building rules and access times with your enquiry. All of Greater London is inside the ULEZ, and our planning allows for it

Will you take on work at estates like Cork Tree Retail Park, close to Highams Park?

Yes. We cover Highams Park and the area around it, including industrial estates, business parks and retail parks such as Cork Tree Retail Park. A few photos and the unit address let us price the work.

Can a joint be sealed if the edges are broken?

Broken arrises have to be put right before resealing. Sealing over them leads to early failure.

Do you cover Highams Park?

Yes. Sites across Highams Park are covered, and the same phone number covers every area.

Can one quote cover more than one building?

Yes. A group of buildings can go on one quote, with one point of contact.

What happens if old sealant might contain asbestos?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

Will you quote for a small job?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

Should maintenance staff do it?

Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

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.

Owners, agents and contractors

We work for building owners and managing agents on sealant work across single buildings or whole portfolios. One quote can cover more than one site, which keeps the paperwork simple.

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Maintenance after handover

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

  • Raise snow-clearing blades over deck joints where possible
  • Note which joints were done, when, and with what
  • Treat a small split as a warning, not a cosmetic issue
  • Include every elevation and deck joint in periodic inspections

Every joint we seal is backed by a 12-month guarantee on workmanship. Record which product went into which joints in the building file.

Floor joints with failed fillers break up quickly under wheels. Damaged edges make the floor rough and wear wheels faster and the broken length grows with every pass. Sealing early protects the edges.

What sets the cost

Before we quote, we look at:

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

Pricing movement joints depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.

Sending details for a quote

The more we know, the firmer the quote. Helpful details to send:

  • Rough lengths or quantities, or drawings if you have them
  • Any specification or named product
  • Whether the building will be occupied during the work
  • The postcode of the building

A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or give us a call on 01277 525 020 or email a schedule or drawings if you’d rather talk the job through.

On site: what to expect

At the end of each section, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. In Highams Park, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.

  1. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  2. Next, we fix a price and confirm the sealant we propose for the movement.
  3. We strip out the old seal and prepare the faces, and we tell you if any edges need repairing first.
  4. Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
  5. Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
  6. We check every joint before sign-off, and the work carries our 12-month guarantee.

Before we start on site

  • Move anything stored against the joints
  • Explain the parking and delivery arrangements
  • For older buildings, check the asbestos register before work

Expansion joint sealing in Highams Park: the local picture

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. Less than 3 miles from Highams Park there are at least three named estates and business parks. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.

Schools such as South Chingford Foundation School have movement joints in their walls and floors that are easy to overlook. Another example is Walthamstow Business Centre, which lies south-east of Highams Park, where floors and yards would be done in stages around the occupiers. Places like Cork Tree Retail Park, 0.9 miles north-west of Highams Park, put trolleys over floor joints inside and cars over slab joints outside.

Highams Park is about 1 mile south of Chingford, in Greater London. Any commercial site in Highams Park is covered, for single jobs and planned programmes alike. 764 places across Greater London fall within our area, Highams Park among them. There’s a separate page for London, about 8 miles away.

We cover the E4, E17 and IG8 postcode districts for movement joints. For a building on May Road, Adam Road and Cecil Road or nearby, we can quote for movement joints. We also cover South Chingford (1 mile north-west), Hale End (1 mile east), Chingford Mount (1 mile north), Chingford Hatch (1 mile north-east) and Chingford (1 mile north) for movement joints. Bigger towns within reach include London (8 miles south-west), City of Westminster (9 miles south-west), Marylebone (8 miles south-west), Kensington (11 miles south-west), St Pancras (7 miles south-west) and Shoreditch (6 miles south-west).

Local landmarks in Highams Park

Nearby you will also find Walthamstow Pump House Museum (2.2 miles south) and Wanstead Hospital (2.3 miles south-east). The countryside around Highams Park includes Highams Park Lake and Pole Hill.

Honest limits

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Waterproofing layers buried beneath the sealant
  • Proprietary pre-formed expansion joint systems
  • Structural movement beyond what the joints were designed for (that needs a structural engineer)

Not sure which it is? You can phone 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.

Joints and surfaces we work on
