How we handle expansion joint sealing in West End

Width, depth and product all have to work together. Joint width must suit the movement and the movement class of the sealant. For wider joints, many sealant makers recommend a width-to-depth ratio, often around 2:1 and the bead bonds to the sides, never the back. If you have water getting into the wall through a failed joint and debris jammed in movement joints, we can put it right, on car park decks and ramps, precast concrete panel joints and podiums and floor movement joints alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in West End, preparation and product choice get the time they need.

Most London buildings can’t shut a car park, loading bay or warehouse floor for long. Joints are done in sections, with bays coned off one after another, so the site keeps operating, at times agreed with the building manager.

Every job we finish is backed by a 12-month workmanship guarantee, in West End as everywhere else we work. If our installation lets you down in that time, we return and fix it.

How the quote is worked out

Your fixed quote is built from the real scope. It takes account of:

  • Whether the work must be split into stages
  • Access and working height
  • Joint width, depth and condition
  • The total length or number of joints

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Details that help us quote

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

  • What the building is and how it’s used
  • Photos of the joints, close up and from further back
  • How the joints are reached, and at what height
  • The asbestos register, for older buildings

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, call the office on 01277 525 020 or send details through our quote form.

Common questions from West End clients

Is Grand Vitesse Industrial Estate, near West End, within your area?

Yes. Our area takes in West End and its surroundings, with estates and business parks such as Grand Vitesse Industrial Estate included. Send details of the unit and the work through our quote form for a quick quote.

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

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 will plan accordingly.

Is any job too small?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

Can you work while the building is occupied?

Yes, as long as we plan it. Tell us your site hours and access windows and we’ll plan around them.

Can weather delay the job?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

Do you seal on top of existing sealant?

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

How do you deal with asbestos in old sealant?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

Different surfaces, different methods

Joints between different materials

Some mixed-material joints suit a hybrid sealant. The choice depends on the substrates and how much the joint moves.

Concrete and precast panel joints

Precast panels often have surface residues that sealant won’t bond to. Proper cleaning and primer where specified give a sound bond, so the new seal holds.

Joints that move: notes for West End

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. The 3 miles around West End take in at least three named trading estates, business parks or retail parks. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.

A campus such as University of Notre Dame, less than half a mile to the south of West End, has long runs of movement joint in its buildings, decks and paving. Another example is Southwark Bridge Business Centre, 1.6 miles to the south-east of West End, where floors and yards would be done in stages around the occupiers.

West End is about 1 mile east of City of Westminster, in Greater London. Our applicators travel to West End for work on movement joints. Our Greater London coverage takes in 764 places, large and small.

We cover the W1F, W1D and W1T postcode districts for movement joints. If your site is on Duck Lane, Drury Lane and Bridle Lane or close by, we can quote for movement joints. Being close to the A301 and A400, West End is easy to get to with materials and equipment. Nearby places we also cover include Seven Dials (1 mile east), St Giles (1 mile north-east), Soho (1 mile west), Chinatown (1 mile south-west) and Covent Garden (1 mile east). A short drive away, we cover Kensington (3 miles west), Walthamstow (7 miles north-east), Whitechapel (3 miles east), Hampstead (4 miles north-west), Ruislip (13 miles west) and Stockwell (3 miles south).

Signs you need expansion joint sealing in West End

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, so we check width and movement before quoting.

Any of the following is a good reason to get the joints checked over:

  • Water dripping through deck or ramp joints
  • Brittle, chalky sealant on external joints
  • Torn sealant in brick or block movement joints
  • Layers of sealant in a movement joint

At a retail site such as Brunswick Centre, which lies north of West End, trolleys, cages and cars run over floor and slab joints all day.

Questions to ask before you book

  • Will failed sealant be removed rather than covered?
  • Whether their applicators hold CSCS cards
  • What site paperwork they can supply
  • The terms of the workmanship guarantee

Questions to ask before you appoint anyone

On site: what to expect

At the end of each section, we remove the tape, clean down and inspect every joint with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. In West End, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. We compare each joint’s width with the movement and the sealant’s capability.
  3. Old sealant and debris are cut out of every joint.
  4. Edges are checked, and we tell you if any need repairing before sealing.
  5. The right sealant goes in at the right depth, bonded to the two sides only.
  6. Each area is handed back after its cure time, under our 12-month guarantee.

Getting the site ready

  • Send your site hours and access windows
  • Point out any areas we must not close
  • Point out parking and an unloading spot

Honest limits

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Broken or spalled joint edges, which need repairing before any sealant goes in
  • Changing the joint layout or spacing of a structure
  • Cracking or settlement that calls for an engineer’s assessment

Not sure which it is? You can ring 01277 525 020 or email a schedule or drawings and we’ll tell you honestly.

Joints and surfaces we work on

  • Precast concrete panel joints
  • Car park decks and ramps
  • Podiums and floor movement joints
  • Cladding panel joints
  • Brickwork movement joints
  • Blockwork control joints

Why it’s worth doing now in West End

A torn seal left alone typically gets worse. Grit and water fill the gap and the material either side breaks up, so a reseal turns into an edge repair as well. Resealing early keeps the work to sealant. Getting scaffold, permits or access booked in West End takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
