Floor joint sealing for Hither Green sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

About our floor joint sealing in Hither Green

Across Hither Green and the rest of Greater London, it runs the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Approximate joint lengths, a few photographs and a floor plan are enough for a quick quote and a visit can be arranged where that is easier. We work on saw-cut induced joints, construction joints and retail and showroom floors, and what we are called in for most is untidy open joints in a retail unit and failing joints at loading bays and dock doors. Most enquiries from Hither Green start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

Most London buildings can’t shut a car park, loading bay or warehouse floor for long. We work through joints a section at a time, closing small areas in turn.

We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application.

What happens if it’s left?

Waiting for a site-wide shutdown often means the joints keep getting worse. Phased in zones, the busiest routes can be treated first while the rest of the floor carries on. Getting scaffold, permits or access booked in Hither Green takes effort, so it makes sense to deal with every failing joint while access is in place.

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

For managing agents and facilities managers

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.

When you manage a building on behalf of an owner, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

When something else is needed

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

  • Unstable slabs moving under traffic
  • Level or flatness problems across the floor
  • Cracks across panels caused by settlement or overload

If you’re not sure, just give us a call on 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.

Joints and surfaces we work on

  • Construction joints
  • Forklift and pallet-truck routes
  • Joints along racking aisles
  • Saw-cut induced joints
  • Loading bays
  • Retail and showroom floors

Warehouse floors and decks around Hither Green

Basement car parks and service yards in London tend to be in use all working day, which is why we work a few bays at a time. Less than 3 miles from Hither Green there are at least three named estates and business parks. Their warehouses, yards and car parks are exactly where joints take the most punishment.

For estates staff at a university like University of Greenwich - Greenwich Campus, 2.1 miles to the north of Hither Green, building and paving joints are part of the planned maintenance list. Across sites such as Greenwich Centre Business Park, 2 miles north of Hither Green, floor and movement joints can be sealed in phases so units keep working. Hospitals like University Hospital Lewisham, 0.8 miles to the west of Hither Green, have multi-storey or surface car parks whose joints carry vehicles round the clock.

On site: what to expect

Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. For a job in Hither Green, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.

  1. A floor survey records every joint, its edges and what crosses it.
  2. You receive a fixed quote showing products and phasing.
  3. Each joint is cut or routed back to clean, sound concrete.
  4. Dust is vacuumed out and primer applied where specified.
  5. Filler or sealant is placed to depth and finished flush.
  6. We hand each phase back when it can take traffic.

Getting the site ready

  • Share the asbestos register for older buildings
  • Confirm the product named in the specification
  • Move anything stored against the joints

Ask for a quote

Send us photos, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.

Related advice

How the quote is worked out

These are the things that shape the price:

  • Which sealant the job calls for
  • Joint width, depth and condition
  • Removal of failed or old sealant
  • Travel to remote or island sites

Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

What to include in your enquiry

A few photographs plus some basic facts will normally do. It helps to include:

  • Clear photos of the problem areas
  • Where the site is, with the postcode
  • Access details, including height
  • Any dates the work must fit around

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, phone 01277 525 020 or email us.

Hither Green: questions and answers

Is hospital work, at somewhere like University Hospital Lewisham, something you do?

Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.

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

Yes, we plan every London job around the building’s own access rules. The building manager’s rules go straight into our method.

What information helps you price floor joint sealing?

Use our quote form, or email photographs and a plan, with the traffic on each area. We then send a fixed quote that shows the products and zones.

What if there’s asbestos in the old mastic?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

Do you use semi-rigid filler or flexible sealant on floor joints?

It depends on the traffic and the movement. Forklift routes generally call for a semi-rigid filler that holds the arrises and joints with more movement take a flexible sealant.

When can forklifts run over new joint filler?

Cure times vary with the product and how cold the slab is. You’ll get a reopening time for each area when we agree the phasing.

Which sealant will you use?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Surface by surface

Flexible floor sealants

A flexible sealant suits perimeter and movement joints away from the heaviest traffic. Closed-cell backing rod goes in first, keeping the bead shallow and gripping only the two faces.

Construction joints

Day joints on busy routes are prone to edge damage. We look at how much they are moving before choosing the treatment.
