Need expansion joint sealing in Orpington?

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

Our process

On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work normally takes a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints. Planning a London job such as one in Orpington starts with access: 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. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  2. A fixed quote follows, naming the sealant and its movement class.
  3. The failed seal is removed and both faces are cleaned until sound and dry, flagging any broken edges that need repair before sealing.
  4. Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
  5. After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
  6. Each joint is inspected and handed over with our 12-month guarantee.

About our expansion joint sealing in Orpington

Joints in car park decks and ramps are among the hardest-working in any building. Wheel loads, grit and de-icing salts attack the seal and the concrete either side, so failed seals soon lead to leaks onto the level below and broken edges. We reseal deck and ramp joints with a trafficable sealant chosen for the movement and the work can be phased so parts of the car park stay open. If you’re dealing with spalled or broken joint edges in floors and decks and hardened, cracked sealant on exposed facades, we can put it right. Facilities teams, main contractors and managing agents in Orpington tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Floor and movement joints in London take heavy use: car park decks, loading bays, shopping centre malls and podiums over occupied space. A failed joint lets water and debris in, and the edges soon spall, so it pays to act early.

We stand by our work with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

Leave it or put it right?

A torn seal left alone usually gets worse. Water and debris get in, the joint jams and the edges spall, so a reseal turns into an edge repair as well. Acting at the first split keeps the cost down. In Orpington, each extra visit means more notices, permits and disruption, so cutting the old sealant out fully and doing it right once is the better route.

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

FAQs: Orpington

Is a hospital such as Orpington Hospital somewhere you can work?

Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.

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

Yes, we plan every London job around the building’s own access rules. The building manager’s rules go straight into our method. All of Greater London is inside the ULEZ, and our planning allows for it

What sealant do you use in movement joints?

We choose a sealant with a movement capability that suits the joint, classified under BS EN ISO 11600. Hybrid or MS polymer products suit some mixed-material joints.

How long will the joint resealing take?

That depends on joint lengths, widths, access and how much old sealant or filler needs removing. As a guide, it usually takes a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints.

Can you quote from photos?

That depends on the size and complexity of the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.

Is Orpington in your area?

Yes. Orpington falls within our area, and you can phone 01277 525 020 or send details through our quote form to get started.

Can the sealant be colour-matched?

Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.

Joints that move: notes for Orpington

Orpington 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. 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.

Schools like Perry Hall Primary School often have long brick elevations with movement joints that age quietly. Across sites such as Nugent Retail Park (0.7 miles north-east of Orpington), floor and movement joints can be sealed in phases so units keep working. Business parks such as Halo Business Park, 0.6 miles north-east of Orpington, have car parks, paved areas and long brick and panel elevations, all with movement joints.

Quoting for work in Orpington

There’s no standard rate for sealant work, since sites vary so much. What we take into account:

  • Induction, permit and paperwork requirements
  • Whether the work must be split into stages
  • Travel to remote or island sites
  • Any access equipment needed

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

Sending details for a quote

We can often quote from photographs and a few details. Please tell us:

  • The postcode of the building
  • Clear photographs of the problem areas
  • Anything awkward about access or site hours
  • Approximate linear metres or a joint schedule

Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. The easiest way is to give us a call on 01277 525 020 or send photos by email.

After the work

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Keep product details with the building records for the next reseal
  • Treat a small split as a warning, not a cosmetic issue
  • Inspect movement joints alongside other routine building checks
  • Keep traffic off new joints until the cure time is up

Snow ploughs and scrapers catch on joint lines. Raising blades over joints where possible protects the seal.

Rain gets into walls through torn brick and block movement joints. It can surface inside as damp a long way from the joint, well after the seal first opened. Resealing promptly prevents internal damage.

Site staff or a sealant specialist?

Putting right a botched joint often costs more than sealing it well at the start, 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.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
