How we handle expansion joint sealing in Barnston

We have been sealing expansion and movement joints for over 20 years, for main contractors, FMs, managing agents and building owners. CHAS accredited, Constructionline member, CSCS-carded applicators and five million pounds of public liability insurance. Workmanship is backed by our 12-month guarantee. The enquiries we see most involve brittle, chalky sealant on external joints and rain penetration at brick or block movement joints, on blockwork control joints, car park decks and ramps and precast concrete panel joints. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Barnston is the same: the right product in a properly prepared joint.

In and around smaller places like Barnston, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

When something else is needed

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Proprietary pre-formed expansion joint systems
  • A joint that has to be widened or re-detailed before it can work
  • Concrete or masonry repairs along the arrises

If you are not sure, just call 01277 525 020 or email the details over and we will give you a straight answer before you book.

Where we work in Barnston

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

Building owners, agents and FMs in Barnston

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

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

After the work

Problems stay small when the joints are checked regularly. In particular:

  • Look over external and deck joints after a hard winter
  • Treat a small split as a warning, not a cosmetic issue
  • Avoid parking heavy plant or pallets on joint lines
  • Include every elevation and deck joint in periodic inspections

Snow ploughs and scrapers catch on joint lines. Raising blades over joints where possible protects the seal and a look at the joints after winter catches any damage.

Unsupported floor joint edges spall under forklift and pallet-truck wheels. Broken arrises jolt trucks, loads and drivers. Keeping the filler or sealant sound protects the floor.

How a job runs

Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. For a building around Barnston, 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 look at the joints, their width and how they’ve failed.
  2. Next, we fix a price and confirm the sealant we propose for the movement.
  3. The failed seal is removed and both faces are cleaned until sound and dry, and we tell you if any edges need repairing first.
  4. We control the depth with backing rod or, in shallow joints, bond-breaker tape.
  5. Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
  6. Finished joints are checked and backed by our 12-month guarantee.

Getting the site ready

  • Tell staff and tenants when we’ll be in
  • Share the asbestos register for older buildings
  • Let us know about inductions and permits

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photographs and a description will do.

Advice

How the job changes by surface

Cladding panel joints

Metal and composite panels shift considerably as temperatures change. A sealant with the right movement class is chosen.

Podium joints

Podiums take foot traffic, planters and weather. We choose a product that copes with feet, wheels and weather.

Traffic, movement and joints around Barnston

Rainfall across the South East, Barnston included, is lower than in many parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, and gritting in cold spells finds its way into open joints. At about 32 miles from central London, Barnston is within reach of the capital. The roads out of London are lined with trade parks and distribution sheds; their floors carry heavy traffic every shift.

Another example is Hoblongs Industrial Estate, 0.7 miles to the north-west of Barnston, where floors and yards would be done in stages around the occupiers. For an occupier at a site such as Martels Industrial Estate, which lies south-west of Barnston, the joints at loading doors and dock levellers typically see the hardest wear.

Common problems we fix in Barnston

Sun, rain and frost age external movement joints. UV hardens the surface, and the sealant loses its ability to stretch.

Site and facilities staff are often the first to spot these:

  • Joints packed with grit and debris
  • Water dripping through deck or ramp joints
  • Water getting into the wall through a failed joint
  • Chipped joint edges on forklift routes

Schools such as Helena Romanes School and Sixth Form Centre have movement joints in their walls and floors that are easy to overlook.

Questions to ask before you appoint anyone

Questions we are asked in Barnston

Is Barnston too small for you to travel to?

No. Small places get the same service as large ones. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.

Will you take on work at estates like Martels Industrial Estate, close to Barnston?

Yes. Estates, retail parks and business parks around Barnston, Martels Industrial Estate among them, are all within reach. A few photos and the unit address let us price the work.

What causes movement joint sealant to fail?

Most often the movement is too much for the product or the joint width. That’s why we check width, depth and movement class before quoting, rather than replacing like for like.

Can one quote cover more than one building?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

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.

Can the sealant be colour-matched?

That depends on the product specified. Some ranges offer many colours, others very few, so we’ll confirm the colours available for the specified product with the quote.

Will you come and look before quoting?

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