Commercial clients in Great Kingshill

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

Expansion joint sealing for commercial buildings in Great Kingshill

Internal floor joints take trolleys, pallet trucks and forklifts. Without a sound filler, joint edges chip and spall under load, so the right filler or sealant for the traffic and movement matters. If the arrises are already broken, we’ll say so before sealing and phasing can keep areas working. We work on brickwork movement joints, blockwork control joints and car park decks and ramps, and what we are called in for most is leaks through car park deck joints onto the level below and new sealant over old, now failing. Looking for mastic applicators who cover Great Kingshill? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

Halls, schools and small commercial buildings near places like Great Kingshill have movement joints in brick, block and concrete too. They’re easily forgotten until water gets in or an edge breaks.

Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

What we can’t put right

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Leaks coming from the membrane rather than the joint seal
  • Damaged metal nosings or cover plates over a joint
  • Broken or spalled joint edges, which need repairing before any sealant goes in

If you are not sure, just phone 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer.

What we seal

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

Common questions from Great Kingshill clients

Will our site in Great Kingshill have to close for joint sealing?

Usually not: we work in sections and hand each one back once it has cured. The phasing plan comes with the quote.

Is Great Kingshill too far out for you?

No. Places such as Great Kingshill are covered as much as the big towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

When can the area be used after sealing?

We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.

Can one quote cover more than one building?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

Will you quote for a small job?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

Do you need to see the site first?

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

What do you charge?

We don’t publish prices, as every site differs. Send photographs or drawings and we’ll price it at a fixed figure.

Different surfaces, different methods

Joints between different materials

Hybrid or MS polymer sealants bond to many substrates. We pick the product for the materials and the movement, and confirm it in the quote.

Podium joints

On podiums, the joint can belong to a larger waterproofing detail. Where the specification calls for sealant, we reseal.

Cost factors for movement joints

The price varies from site to site. Expect it to depend on:

  • Induction, permit and paperwork requirements
  • How much existing material needs removing
  • The product specified
  • Working within restricted access windows

What a job costs comes down to how many linear metres there are, how much old material needs removing and the access. Call for a quote when you are ready.

What we need to price the job

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

  • The product your specification calls for
  • How the joints are reached, and at what height
  • The asbestos register, for older buildings
  • Approximate linear metres or a joint schedule

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, phone 01277 525 020 or send photos by email.

On site: what to expect

Tell us your site hours and access windows and we’ll plan around them. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. Rural sites near Great Kingshill may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  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.
  4. Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
  5. After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
  6. Finished joints are checked and backed by our 12-month guarantee.

Before we start on site

  • Tell us what induction or permit system the site runs
  • Have the specification and drawings to hand
  • Clear stock, furniture or equipment away from the joints

Getting a fixed quote

Let us know the site, the scope and your timescale, and a fixed quote will follow. To get it moving, give us a call on 01277 525 020 or email drawings and photos.

Maintenance after handover

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

  • Clear dirt from joint lines during routine cleaning
  • Keep traffic off new joints until the cure time is up
  • Inspect exposed joints once the cold weather has passed
  • Brief car park operatives to protect joint lines during winter clearance

On car parks, winter clearance can damage deck joint sealant. Raising blades over joints where possible protects the seal.

On a multi-storey car park, a failed joint usually shows up as a leak onto the deck underneath. That water often carries de-icing salts with it and it can affect the structure over time. Resealing early limits the damage.
