Expansion joint sealing near Chinbrook

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Looking after the joints

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Inspect exposed joints once the cold weather has passed
  • Record the sealant used and the date in the O&M file
  • Avoid parking heavy plant or pallets on joint lines
  • Report split or peeling joint sealant early

In warehouses, forklift and pallet-truck routes take the most wear. Keep racking feet and heavy point loads off joint lines, and report any chipped edges early.

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. Keeping the filler or sealant sound protects the floor.

Expansion joint sealing in Chinbrook

Few joints take as much punishment as those in a car park. Wheel loads, grit and de-icing salts attack the seal and the concrete either side; water dripping through to the deck below is often the first sign. A sealant suited to traffic and the expected movement goes in, phasing bays so the car park can stay in use. If you have new sealant over old, now failing and expansion joints split through the centre of the bead, we can help, on precast concrete panel joints, blockwork control joints and car park decks and ramps alike. Most enquiries from Chinbrook start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

Most London buildings can’t shut a car park, loading bay or warehouse floor for long. Joints are done in sections, with bays coned off one after another, so the site keeps operating.

Work we carry out comes with a 12-month guarantee. Should something we installed fail, call the office on 01277 525 020 or email us and we will come back to it.

When to bring in a specialist

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Expansion joint sealing around Chinbrook: points for this area

Few London car parks or loading bays can be taken out of use for more than a short spell, which is why we work a few bays at a time. At least three named trading, business or retail sites lie within about 3 miles of Chinbrook. Sites like these are full of saw-cut floor joints, yard slabs and car park joints.

A healthcare site such as Eltham Community Hospital, 1.6 miles north-east of Chinbrook, depends on car parks, ramps and service yards whose joints take traffic all day. For estates staff at a university like University of Greenwich - Avery Hill, which lies north-east of Chinbrook, building and paving joints are part of the planned maintenance list. At a retail site such as The Mall (2.1 miles south of Chinbrook), trolleys, cages and cars run over floor and slab joints all day.

Chinbrook is about 1 mile south-west of Eltham, in Greater London. Businesses, contractors and managing agents in Chinbrook use us for work on movement joints. Chinbrook is one of 764 places in Greater London on our list. There’s a separate page for London, about 7 miles away.

How the quote is worked out

We price every job individually. The things that drive the figure:

  • Joint width, depth and condition
  • How accessible the joints are
  • Location, for remote and island sites
  • Removal of failed or old sealant

What a job costs comes down to how many linear metres there are, how much old material needs removing and the access. Call for a quote when you’re ready.

Details that help us quote

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

  • The asbestos register, for older buildings
  • Photos of the joints, close up and from further back
  • When you need the work done
  • Rough lengths or quantities, or drawings if you have them

Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. To get it moving, call the office on 01277 525 020 or email a schedule or drawings.

How the job changes by surface

Internal floor movement joints

Warehouse and retail floors have saw-cut induced joints and construction joints. Trafficked floor joints often get a semi-rigid filler.

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.

Why act early in Chinbrook

Resealing is usually the answer, not replacing the element. Where the edges are sound, cutting out and resealing is enough. If the edges have broken up, we’ll tell you they need repairing first. Getting scaffold, permits or access booked in Chinbrook takes effort, so it makes sense to deal with every failing joint while access is in place.

Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Why us?

  • A range of standard colours, depending on the product
  • Fully insured, including public liability cover
  • CSCS-carded applicators

Questions about Chinbrook

Can you work at a site such as Green Lane Business Park, by Chinbrook?

Yes, sites like Green Lane Business Park are within our area, along with the rest of Chinbrook. Photos and a short description are enough for a first look.

Can you cope with the access rules in a London building?

Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Share the building’s contractor rules and we’ll work to them. We allow for the ULEZ, which covers every borough

Can you work on car park ramps and decks?

Yes, we do. Tyre loads, grit and de-icing salts make these some of the hardest joints to keep sealed, and we will tell you if any edges need repairing first.

What timescale should we allow for resealing expansion joints?

Expect a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints. We’ll confirm when each area can be used again.

Will you just go over the old sealant?

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.

How much does the work cost?

It depends on the job: quantities, access, the product and any phasing. Call for a quote.

Is movement joint sealing guaranteed?

Each job is backed by a 12-month guarantee on the workmanship. Damage from later works or traffic loads outside the joint’s design isn’t a workmanship fault.

How a job runs

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. Most London premises stay occupied while we are on site, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.

  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 flag anything that needs an engineer.
  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.

Preparing the site

  • Agree which areas must stay open
  • Clear stock, furniture or equipment away from the joints
  • Let building users know which areas are affected
