About our expansion joint sealing in Broadstone

We cover the full range of movement joints: brickwork and blockwork joints, precast and cladding panel joints, concrete joints, car park decks and ramps, podiums and floor movement joints. Every one calls for a sealant picked for its movement, exposure and traffic and we name it in the quote. If you are dealing with layers of sealant in a movement joint and rain penetration at brick or block movement joints, we can put it right, whatever the surface. Whoever orders the work in Broadstone, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.

Smaller community and commercial buildings around Broadstone have their own movement joints in walls and floors. They’re easily forgotten until water gets in or an edge breaks.

Our workmanship is guaranteed for 12 months, in Broadstone as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

General trades versus a specialist

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

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 easy to get wrong without experience.

Your questions answered

Will you take on work at estates like Roebuck Business Park, close to Broadstone?

Yes. We cover Broadstone and the area around it, including industrial estates, business parks and retail parks such as Roebuck Business Park. A few photographs and the unit address let us price the work.

Do we have to stop operations in Broadstone while the joints are sealed?

Normally not: we work in sections and hand each one back once it has cured. Tell us which hours and entrances we can use and we’ll plan from there.

Are you insured?

Yes. We’re fully insured, and the certificate can go with your quote.

Can one quote cover more than one building?

Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.

Does weather matter for sealant work?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

How long before the joints can be used?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

How long do sealant joints last?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

What sealant work can’t fix

We check first that sealant really is the fix. It isn’t the answer for:

  • Cracking or settlement that calls for an engineer’s assessment
  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
  • A joint that has to be widened or re-detailed before it can work

If in doubt, give us a call on 01277 525 020 or use the quote form and we will say what we think before you book.

What we seal

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

Different surfaces, different methods

Internal floor movement joints

Wheeled traffic chips floor joint edges that aren’t supported. We match the product to the traffic and the movement, and tell you if edges need repairing first.

Joints between different materials

Some mixed-material joints suit a hybrid sealant. We pick the product for the materials and the movement, and confirm it in the quote.

Aftercare for building managers

Keep the joints in good shape with a few simple steps:

  • Leave barriers in place until fresh joint sealant has cured
  • Avoid parking heavy plant or pallets on joint lines
  • Brief car park operatives to protect joint lines during winter clearance
  • Act on the first tear or lifting edge rather than waiting

Floor joints on main traffic routes need watching more closely than the rest. Keep racking feet and heavy point loads off joint lines and flag chipped arrises before they spread.

External wall joints that fail let rain into the masonry and cavity. It can surface inside as damp a long way from the joint. Catching it early keeps the water outside.

Why act early in Broadstone

Some quotes just add sealant over the old bead. A bead laid on top of the failed one neither grips nor flexes properly, so it fails quickly. Full removal and preparation is in every quote. Around Broadstone, it’s better to renew all the failing joints at once. Send photographs of each area and we’ll quote for the lot.

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

Why clients in Broadstone choose us

  • Our applicators hold CSCS cards
  • Coloured sealants to suit the setting, where available
  • Old sealant cut out, never sealed over
  • RAL and finish matching where the product range allows

From enquiry to sign-off

Tell us your site hours and access windows and we’ll plan around them. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. Rural sites near Broadstone may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  1. We look at the joints, their width and how they’ve failed.
  2. You get a fixed quote with the product and its movement capability stated.
  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. Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
  5. Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
  6. Finished joints are checked and backed by our 12-month guarantee.

Preparing the site

  • Let us know about inductions and permits
