Expansion joint sealing in Herne Common, done properly

Every structure moves a little, all the time: they expand in the heat, shrink as they dry, and shift under load. Expansion and movement joints are built in so the structure can move without cracking, and the sealant in them keeps water and debris out. We seal and reseal movement joints in walls, panels, decks and floors on sites in Herne Common. We work on blockwork control joints, precast concrete panel joints and podiums and floor movement joints, and the failures we’re asked to look at most are expansion joints filled with dirt and stones and sealant pulling off the joint face. One point of contact handles commercial sealant work in Herne Common from the first photographs to the final walk-round, whether it’s one building or several.

Halls, schools and small commercial buildings near places like Herne Common have movement joints in brick, block and concrete too. They tend to be overlooked until something leaks or cracks.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Maintenance after handover

Regular inspection catches problems early. In particular:

  • Keep product details with the building records for the next reseal
  • Clear dirt from joint lines during routine cleaning
  • Plan racking layouts so feet don’t land on a joint
  • Keep traffic off new joints until the cure time is up

Fresh joint sealant needs its full cure time before it takes traffic or water. The time varies with product, conditions and joint depth, and we confirm it for each area before we leave. Barriers left in place until then protect the finish.

When one joint fails, others of the same age are rarely far behind. 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.

Common questions from Herne Common clients

Does the sea air around Herne Common change the choice of sealant?

It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We check the specified product suits the exposure and pay close attention to preparation.

Is Herne Common too far out for you?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Will your applicators have CSCS cards?

Yes. Our applicators hold CSCS cards.

Are you fully insured?

Yes. We are fully insured, including public liability cover.

What if there’s asbestos in the old mastic?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

How long will the joint resealing take?

Expect a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing, with phasing where areas must stay open. We will confirm when each area can be used again.

Can you quote from photographs?

It depends on the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs normally get a visit.

How the quote is worked out

The price varies from site to site. It mainly depends on:

  • Which sealant the job calls for
  • Backing rod, priming and other preparation
  • Travel to remote or island sites
  • Quantities, in metres or numbers

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

However big the job, these details speed things up:

  • Where the site is, with the postcode
  • The asbestos register, for older buildings
  • When you need the work done
  • Anything awkward about access or site hours

A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or phone 01277 525 020 or email drawings and photos to discuss it first.

Surface by surface

Cladding panel joints

Metal and composite panels shift considerably as temperatures change. The joints need a low-modulus sealant with enough movement capability.

Brickwork and blockwork joints

Long brick and block elevations have movement joints at intervals. They take a low-modulus sealant with a movement class to suit.

Do you need expansion joint sealing in Herne Common?

Sealant peeling cleanly off one side is an adhesion failure. Poor preparation, a skipped primer, or sealant bonded to the back of the joint are typical reasons, and it’s common on joints sealed in a hurry.

Things that usually lead to an enquiry:

  • Joints packed with grit and debris
  • New sealant over old, now failing
  • Sealant peeling off one face of the joint
  • Rain penetration at brick or block movement joints

Phasing is what makes joint work possible on busy sites such as St. Augustine's Business Park (2.3 miles north-west of Herne Common): one bay, aisle or car park row at a time.

Our contractor checklist

What sealant work can’t fix

A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be any of the following:

  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
  • Cracking or settlement that calls for an engineer’s assessment
  • Concrete or masonry repairs along the arrises

If in doubt, phone 01277 525 020 or send details through our quote form and we will say what we think.

Where we work in Herne Common

Diagnose, treat, sign off

Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. For a building around Herne Common, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. We start with photographs, approximate lengths and any drawings, visiting where needed.
  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.

Preparing the site

  • Share the asbestos register for older buildings
  • Let building users know which areas are affected
  • Confirm the product named in the specification
