About our expansion joint sealing in Addington

Width, depth and product all have to work together. The joint has to be wide enough for the expected movement and the sealant’s movement capability, and depth is controlled using closed-cell backing rod, or bond-breaker tape in shallow joints. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises, and the bead is tooled so it grips the two faces alone. Site teams most often ask us about chipped joint edges on forklift routes and rain penetration at brick or block movement joints, across car park decks and ramps, podiums and floor movement joints and blockwork control joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Addington is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

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, at times agreed with the building manager.

Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

For managing agents and facilities managers

Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first, with CSCS-carded applicators on site.

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Addington can form part of a wider programme across Greater London.

Why it’s worth doing now in Addington

Re-sealing with the same product that failed is often a false economy. A higher movement class, or a design change by the engineer, may be needed. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

Why appoint us

  • One number for every site we cover
  • RAL and finish matching where the product range allows
  • Joints cleaned back to sound surfaces
  • Standard and matched colours in many product ranges

Aftercare for building managers

For the best life from the joints:

  • Keep traffic off new joints until the cure time is up
  • Raise snow-clearing blades over deck joints where possible
  • Check joints after long freezing spells
  • Clear dirt from joint lines during routine cleaning

In warehouses, forklift and pallet-truck routes take the most wear. Avoid standing heavy loads or racking legs on the joints.

Unsupported floor joint edges spall under forklift and pallet-truck wheels. Broken arrises jolt trucks, loads and drivers, and the damage spreads along the joint. Keeping the filler or sealant sound protects the floor.

Traffic, movement and joints around Addington

Few London car parks or loading bays can be taken out of use for more than a short spell, so we seal in sections and hand areas back as each cures. At least three named trading, business or retail sites lie within about 3 miles of Addington. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.

With Addington inside the ULEZ and kerb space scarce, we sort access and loading before the first day on site. A healthcare site such as Bethlem Royal Hospital, 1.7 miles to the north of Addington, depends on car parks, ramps and service yards whose joints take traffic all day. Another example is Chaffinch Business Park (2.7 miles north of Addington), where floors and yards would be done in stages around the occupiers.

Addington is about 3 miles south-east of Ashburton, in Greater London. If you are looking for expansion joint sealing in Addington, we can help. Addington is one of 764 places in Greater London on our list for movement joints. London is covered too, some 10 miles away.

Commercial sites across CR0, CR2 and BR4 are covered. We cover commercial and managed buildings on Lodge Lane, Falconwood Road and Addington Village Road. Close to Addington, our area also takes in Coney Hall (1 mile north), Forestdale (1 mile south), Spring Park (1 mile north), New Addington (1 mile south-east) and Selsdon (1 mile south-west). Further afield, our area takes in London (10 miles north), City of Westminster (12 miles north-west), Marylebone (12 miles north-west), Kensington (12 miles north-west), St Pancras (12 miles north) and Shoreditch (12 miles north).

Common questions from Addington clients

Is Vulcan Way Industrial Estate, near Addington, within your area?

Yes. Estates, retail parks and business parks around Addington, Vulcan Way Industrial Estate among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

Would you work within a site like Bethlem Royal Hospital?

Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.

Will you come and look before quoting?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit.

Who decides which product is used?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

How long do sealant joints last?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

What site paperwork can you supply?

Requirements differ from site to site, so tell us what you need and we’ll confirm it when we quote.

How do we ask for 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 photos and a postcode.

From enquiry to sign-off

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. In Addington, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.

  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. Each joint is inspected and handed over with our 12-month guarantee.

Getting the site ready

Advice

What sets the cost

To price the job, we consider:

  • Induction, permit and paperwork requirements
  • Distance, for remote addresses
  • How much there is to seal
  • Any access equipment needed

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

What we need to price the job

Good information means a firmer quote. When you get in touch, include:

  • Any dates the work must fit around
  • Where the site is, with the postcode
  • How the joints are reached, and at what height
  • Asbestos survey details if the building is older

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

General trades versus a specialist

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.

For most general trades, sealant is a sideline. 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.
