Expansion joint sealing in Friday Hill, done properly

The seal is what lets a movement joint do its job. Once it fails, water, grit and debris get in; the joint jams, its edges take the load and the arrises spall. Dealt with early, it stays a sealant job rather than a concrete or masonry repair. Most enquiries involve movement joints with split or torn sealant and new sealant over old, now failing, on precast concrete panel joints, cladding panel joints and brickwork movement joints. Searching for sealant specialists in Friday Hill? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

London’s floor joints are concentrated in warehouses and trade units, car parks, podiums and decks. Planning a job in Friday Hill means thinking about access, loading times and the ULEZ as well as the joints.

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

What sealant work can’t fix

Honesty saves time and money. New sealant won’t cure:

  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
  • Crumbling edges that would give a new bead nothing sound to grip
  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)

If in doubt, call the office on 01277 525 020 or email a schedule or drawings and we will say what we think.

Joints and surfaces we work on

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

Should maintenance staff do it?

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

Questions about Friday Hill

Can you work at a site such as Cork Tree Retail Park, by Friday Hill?

Yes, sites like Cork Tree Retail Park are within our area, along with the rest of Friday Hill. A few photographs and the unit address let us price the work.

Can you cope with the access rules in a London building?

Yes, we plan every London job around the building’s own access rules. Say when the building is occupied and when it’s quiet, and we will plan accordingly. We allow for the ULEZ, which covers every borough

Is Friday Hill in your area?

Yes. Sites across Friday Hill are covered.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and we will price the work to it.

What if the joint edges are damaged?

The edges have to be sound. Where they’ve broken up, we will tell you they need repairing first so you’re not paying for a bead that won’t hold.

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 will plan around them.

When can you be on site?

The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.

Slabs, ramps and loading bays in Friday Hill

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.

Places like Cork Tree Retail Park (to the west of Friday Hill) put trolleys over floor joints inside and cars over slab joints outside. Schools such as Longshaw Primary School have movement joints in their walls and floors that are easy to overlook.

Surface by surface

Brickwork and blockwork joints

Brick and block edges need careful preparation. We clean them back to sound material and prime where the manufacturer specifies.

Concrete and precast panel joints

Joints between precast panels open and close with temperature and loading. The sealant needs the right movement capability and a controlled depth.

Owners, agents and contractors

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

Common problems we fix in Friday Hill

Weathering wears down sealant on exposed elevations and decks. In time the bead chalks, stiffens and cracks.

If one of these sounds familiar, it’s time for a closer look:

  • Rain penetration at brick or block movement joints
  • New sealant over old, now failing
  • Debris jammed in movement joints
  • Expansion joints split through the centre of the bead

University campuses such as University of Portsmouth Walthamstow Campus (2.9 miles south-west of Friday Hill) have car parks, paved walkways and building elevations with movement joints.

Questions to ask before you appoint anyone

How a job runs

Site rules come first: signing in, inductions and any permit to work. Once we’re cleared to begin, we take the joints in the sequence agreed with you. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.

  1. We start with photographs, approximate lengths and any drawings, visiting where needed.
  2. Joint widths and expected movement are checked against what the sealant can take and tell you if the design looks wrong for the movement.
  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. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Each area is handed back after its cure time, under our 12-month guarantee.

Preparing the site

  • Arrange parking or a loading space
  • Share your working hours and any access restrictions
  • Agree which areas must stay open
