A campus such as Buckinghamshire New University, 3.8 miles to the south-west of Ley Hill, has long runs of movement joint in its buildings, decks and paving. In a school such as Ley Hill School, movement joints in brick, block and hall floors tend to be forgotten until they leak.

What we can’t put right

Being straight saves everyone time. Fresh joints won’t solve:

  • A joint that has to be widened or re-detailed before it can work
  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
  • Movement on a scale no sealant is meant to absorb

Not sure which it is? You can call the office on 01277 525 020 or email a schedule or drawings and we’ll tell you honestly before you book.

What we seal

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

When to bring in a specialist

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

When to call us in Ley Hill

Car park decks and floors face loads that walls never see. Tyres and wheels press on the edges and the sealant, while de-icing salts and grit attack the seal. The product has to be suited to the traffic.

Most enquiries start with one or more of the following:

  • Leaks through car park deck joints onto the level below
  • Spalled or broken joint edges in floors and decks
  • Brittle, chalky sealant on external joints
  • Rain penetration at brick or block movement joints

At places like Fairview Industrial Estate (2.4 miles south of Ley Hill), joints are sealed a section at a time so operations carry on.

Choosing a commercial sealant contractor

Owners, agents and contractors

Building owners and managing agents use us on sealant work across single buildings or whole portfolios. One quote can cover more than one site, which keeps the paperwork simple.

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.

Your questions answered

Is hospital work, at somewhere like Amersham Hospital, something you do?

Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.

Is Ley Hill too far out for you?

No. Small places get the same service as large ones. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Can the building stay open while you work?

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

When can the area be used after sealing?

Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.

Which sealant will you use?

A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Can you work on car park ramps and decks?

Yes. Let us know the opening hours and which levels or bays have to stay available.

When can you be on site?

We are in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.

After the work

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Raise snow-clearing blades over deck joints where possible
  • Avoid parking heavy plant or pallets on joint lines
  • Include every elevation and deck joint in periodic inspections
  • Inspect exposed joints once the cold weather has passed

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

Joints sealed at the same time generally fail around the same time. Inspecting the whole run is worth the effort, so the work can be planned rather than rushed. We can suggest an order, worst joints first.

From enquiry to sign-off

Occupied buildings need a little choreography. We sign and contain the area we’re in, with routes through the building left open and work section by section so the rest of the building stays in use. Smaller jobs around Ley Hill can be grouped with others nearby. A fixed quote is given before anything starts.

  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 and tell you if the design looks wrong for the movement.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  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. Areas reopen once cured, and the work carries our 12-month guarantee.

What we need from you

  • Point out any areas we must not close
  • Arrange parking or a loading space
  • Send asbestos survey details if the building is pre-2000

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.
