Expansion joint sealing in Fairlop

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

How a job runs

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. Planning a London job such as one in Fairlop starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we will schedule to suit.

  1. First, the joints are inspected for width, movement and the type of failure.
  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, and we tell you if any edges need repairing first.
  4. We control the depth with backing rod or, in shallow joints, bond-breaker tape.
  5. Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
  6. We check every joint before sign-off, and the work carries our 12-month guarantee.

Preparing the site

  • Send your site hours and access windows
  • Move anything stored against the joints
  • Have the specification and drawings to hand

Advice

Expansion joint sealing in Fairlop, done properly

Buildings and slabs are never completely still: temperature, moisture, shrinkage and loading all make materials grow and shrink. Movement joints are where that movement is absorbed. We seal and reseal movement joints in walls, panels, decks and floors for buildings in Fairlop. The enquiries we see most involve spalled or broken joint edges in floors and decks and water dripping through deck or ramp joints, across cladding panel joints, precast concrete panel joints and blockwork control joints. For commercial sealant work in Fairlop, you deal with one contact from quote to sign-off, whether it’s one building or several.

Areas such as a loading bay or car park deck in Fairlop normally have to stay in use. We work through joints a section at a time, closing small areas in turn, at times agreed with the building manager.

We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Cost factors for movement joints

Before we quote, we look at:

  • Removal of failed or old sealant
  • Travel to remote or island sites
  • The site’s rules and procedures
  • Backing rod, priming and other preparation

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.

Details that help us quote

However big the job, these details speed things up:

  • The type of building and who uses it
  • Whether an asbestos survey exists
  • Any specification or named product
  • Any dates the work must fit around

Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. The easiest way is to ring 01277 525 020 or email us.

Expansion joint sealing in Fairlop: the local picture

At least three named trading, business or retail sites lie within about 3 miles of Fairlop. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest. 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.

For an estate such as King George Hospital, which lies south-east of Fairlop, the joints in ramps, decks and long building elevations all need attention over time. Campuses like University of Portsmouth Walthamstow Campus (to the west of Fairlop) mix old and new buildings, with movement joints wherever they meet. Schools like Fairlop Primary School often have long brick elevations with movement joints that age quietly.

Fairlop is about 2 miles east of Woodford, in Greater London. Our applicators travel to Fairlop for work on movement joints, handled exactly as we handle every other area. Fairlop is one of 764 places in Greater London on our list. We also cover London, some 10 miles away.

We cover the IG6, IG7 and IG5 postcode districts. For a building on Hazel Lane, Hobart Road and Hughes Road or nearby, send details and we’ll quote for movement joints. Close to Fairlop, our area also takes in Fullwell Cross (1 mile south), Barkingside (1 mile south), Newbury Park (2 miles south), Gants Hill (2 miles south) and Redbridge (2 miles south-west).

Doing it in-house

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

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.

Your questions answered

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. The ULEZ covers the whole of Greater London, which we allow for

Can you take on a job at a hospital such as King George Hospital?

Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.

Can you work while the building is occupied?

Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.

Will you quote for a small job?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

Why has the sealant in our expansion joints split?

The common causes are poor preparation, three-sided adhesion, the wrong movement class and weathering. We diagnose which one it is before resealing, because the fix differs.

Do you seal on top of existing sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

Does weather matter for sealant work?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

Maintenance after handover

Keep the joints in good shape with a few simple steps:

  • Report split or peeling joint sealant early
  • Leave barriers in place until fresh joint sealant has cured
  • Keep scrapers and ploughs from dragging across joint sealant
  • Keep racking legs and heavy point loads off floor joints

Keep wheels, feet and water off new joints until the sealant has cured. The time varies with product, conditions and joint depth, and we confirm it for each area before we leave. Barriers left in place until then protect the finish.

A failed deck joint lets water straight through to the level below. Salty water dripping through stains soffits and lands on parked vehicles. Sealing the joint promptly stops it at source.

Leave it or put it right?

Re-sealing with the same product that failed is often a false economy. If the joint is too narrow or the product wrong for the movement, it needs a different approach and we’ll tell you honestly. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.

The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.

Different surfaces, different methods

Internal floor movement joints

Floor joints include saw-cut joints and construction joints. Trafficked floor joints often get a semi-rigid filler and a flexible sealant where the joint moves more.

Podium joints

On podiums, the joint can belong to a larger waterproofing detail. Where the specification calls for sealant, we reseal, and tell you if the problem looks like the waterproofing below.
