Expansion joint sealing for Farmoor sites

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

Expansion joint sealing in Farmoor

Our movement joint work takes in walls, panels, decks and floors: vertical joints in brick and block facades, joints between precast or cladding panels, concrete slab and deck joints, ramps, podiums and internal floors. Every one calls for a sealant picked for its movement, exposure and traffic, and we will confirm the choice in the quote. We work on car park decks and ramps, blockwork control joints and precast concrete panel joints, and the usual reasons a site gets in touch are weathered movement joint sealant that no longer flexes and leaks through car park deck joints onto the level below. Searching for sealant specialists in Farmoor? We have been sealing commercial buildings since 2005.

Smaller community and commercial buildings around Farmoor have their own movement joints in walls and floors. They’re easily forgotten until water gets in or an edge breaks.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application.

When to call us in Farmoor

Most movement joint failures come down to the joint stretching further than the sealant can take. Cohesive failure, a split through the centre, typically means the joint or product wasn’t right for the movement. The same product in the same joint tends to fail again unless width and product are reviewed.

Site and facilities staff are often the first to spot these:

  • Joints packed with grit and debris
  • Sealant pulling off the joint face
  • Chipped joint edges on forklift routes
  • Expansion joints split through the centre of the bead

Retail centres such as West Way Shopping Centre (to the east of Farmoor) have floors, service yards and car parks with joints under constant traffic.

Our contractor checklist

Owners, agents and contractors

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

General trades versus a specialist

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Diagnose, treat, sign off

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself 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, and we clear our waste as we work. Jobs in and around smaller places like Farmoor are usually planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. Joint widths and expected movement are checked against what the sealant can take.
  3. Old sealant and debris are cut out of every joint.
  4. Any broken arrises or friable edges are flagged before work goes further.
  5. The right sealant goes in at the right depth, bonded to the two sides only.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

What we need from you

  • Let us know about inductions and permits
  • Make sure the joints can be reached
  • Send any specification or drawings in advance

How the job changes by surface

Podium joints

Podiums take foot traffic, planters and weather. We choose a product that copes with feet, wheels and weather.

Brickwork and blockwork joints

A brick movement joint full of old mortar or debris can’t close. Everything is raked out before backing and sealant go in, and tell you if the joint looks too narrow for the movement.

FAQs: Farmoor

Does your area include sites such as Oakfields Industrial Estate, near Farmoor?

Yes, sites like Oakfields Industrial Estate are within our area, along with the rest of Farmoor. Send details of the unit and the work through our quote form for a quick quote.

Is Farmoor off your patch?

Not at all. Farmoor is within our area. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.

What about RAMS and site documents?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.

Can you seal car park deck joints?

Yes. Tell us how the car park is used and which areas must stay open, and we will plan the phasing around it.

How do I request a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.

Why has the sealant in our expansion joints split?

The common causes are poor preparation, three-sided adhesion, the wrong movement class and weathering. Working out the cause comes first since each needs a different fix.

Do you offer coloured sealant?

It depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.

What happens if it’s left?

Sealing over a failed movement joint is a common shortcut. A bead over the old seal can’t bond or flex. We cut out the old seal and prepare the faces every time. Older rural buildings around Farmoor move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

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 we will put a fixed figure on it.

What you get with us

  • Fully insured, including public liability cover
  • Work carried out by CSCS-carded applicators

Warehouse floors and decks around Farmoor

Less than 3 miles from Farmoor 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. Farmoor is in the South East, one of the UK’s drier regions. External slab and deck joints still need a dry, clean joint to seal, while winter salting gets into any joint left open.

Across sites such as Oasis Business Park, which lies north-west of Farmoor, floor and movement joints can be sealed in phases so units keep working. Large sites such as Radcliffe Infirmary, 3.7 miles east of Farmoor, have car parks, service roads and long elevations with movement joints in brick and panels.
