Common questions from Orpington clients

Will you take on work at estates like Halo Business Park, close to Orpington?

Yes, sites like Halo Business Park are within our area, along with the rest of Orpington. Send details of the unit and the work through our quote form for a quick quote.

Can you work in a London building with booked loading and goods-lift slots?

Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly. We allow for the ULEZ, which covers every borough

What guarantee do you give on joint filling?

There is a 12-month guarantee on our workmanship and the work is covered by public liability insurance.

Are you fully insured?

Yes. Our insurance certificate can be sent alongside the quote.

What do you need from us to quote?

A rough joint length, a few photographs and a site plan are typically enough for a quick quote. For larger floors, a site visit is often best, and you can ring 01277 525 020 or send details through our quote form to arrange it.

Will you just go over the old sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

Which is better for warehouse joints, filler or sealant?

There isn’t one answer for a whole floor. Where hard wheels cross, a semi-rigid filler is typically right and perimeter or movement joints need flexibility. You’ll see the choice for each area in the quote.

Floor joint sealing for commercial buildings in Orpington

We work on warehouse aisles, dock areas, factory floors, retail units and showrooms. Pricing depends on the length of joint, how worn the edges are and when we can get in and the figure is fixed before work begins. We work on retail and showroom floors, saw-cut induced joints and forklift and pallet-truck routes, and what we’re called in for most is a gap opening alongside old joint filler and unfilled floor joints collecting dirt and grit. Whoever orders the work in Orpington, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Distribution and trade units on London’s edges, and deck car parks across the city, hold most of its floor and slab joints. Planning a job in Orpington means thinking about access, loading times and the ULEZ as well as the joints.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

After the work

To get the most from the new sealant:

  • Keep trucks off new joints until we say they’re ready
  • Walk the main routes and inspect joint lines on a regular cycle
  • Put loading bays at the top of the list
  • Stop forks and pallets being dragged across joints

Keep traffic off fresh joints until the time we give you, and it’s worth enforcing. Cones or barriers stop the first driver cutting the corner.

Joints are easiest to look after when someone checks them regularly. A phased plan, worst routes first, spreads the work out so nothing is left to fail.

What we can’t put right

We check first that sealant really is the fix. It isn’t the answer for:

  • Worn screed or surface finishes
  • Uneven floors that need grinding or levelling
  • Joint edges that have already broken away, which need repairing before filling (we will tell you if so)

If you’re not sure, just phone 01277 525 020 or email the details over and we’ll give you a straight answer.

Joints and surfaces we work on

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

Doing it in-house

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

What affects the price in Orpington

The price varies from site to site. It mainly depends on:

  • Which sealant the job calls for
  • Any access equipment needed
  • Quantities, in metres or numbers
  • Phasing around occupants

Pricing floor joints depends on quantities, condition and access, and any specification that applies. Call for a quote.

Before you send an enquiry

There’s no need for a formal survey. A few details are enough to get going:

  • Access details, including height
  • Specification clauses that apply
  • The postcode of the building
  • When you need the work done

Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to ring 01277 525 020 or use the quote form with what you know.

Our process

We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. 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 agree the traffic routes and phasing with your site team.
  2. We point out joints whose edges need repairing first.
  3. We clear each run back to clean concrete.
  4. The chosen filler or sealant goes in flush with the slab.
  5. Each area is handed back when ready for traffic.

What we need from you

  • Tell us what induction or permit system the site runs
  • Share the asbestos register for older buildings
  • Arrange parking or a loading space

Quotes

The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or call the office on 01277 525 020 or send details through our quote form to discuss it first.

What the job involves on each surface

Retail and showroom floors

Retail work is phased around trading. Give us your opening pattern and access windows and the phasing follows.

Forklift and pallet-truck routes

Truck routes take traffic all day, so their joints wear fastest. Semi-rigid fillers are widely used on these routes to hold the edges up.
