Expansion joint sealing for Longcroft sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Expansion joint sealing in Longcroft, done properly

A movement joint only works while its seal does. When the sealant splits or lets go, the gap fills with dirt and water; the joint jams, its edges take the load and the arrises spall. Resealing at the first signs of failure is far cheaper than repairing the material either side. Site teams most often ask us about rain penetration at brick or block movement joints and water dripping through deck or ramp joints, across podiums and floor movement joints, blockwork control joints and brickwork movement joints. A single leaking joint is often how a building in Longcroft first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Weather windows decide external joint work around a place like Longcroft: dry faces and the right temperature are essential, so dates have some give. Internal floors can be done whenever suits the site.

A 12-month guarantee applies to all our work. If an installation problem shows up, speak to us on 01277 525 020 or use the quote form and we’ll arrange a return visit.

Where floor joints take the most wear near Longcroft

Being in the east of Scotland, Longcroft gets less rain than the west coast. Freezing weather and salt still attack open external joints. Resealing before the cold months helps protect the edges.

Hospitals like Forth Valley Royal Hospital (to the north-east of Longcroft) have multi-storey or surface car parks whose joints carry vehicles round the clock. Estates like Chattan Industrial Estate, 2.1 miles to the east of Longcroft, combine warehouse slabs, yards and loading bays, all with joints under wheels.

What affects the price in Longcroft

To price the job, we consider:

  • Travel to remote or island sites
  • The total length or number of joints
  • Whether the work must be split into stages
  • How much existing material needs removing

We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we will price your job on its own details.

What to include in your enquiry

It doesn’t need to be a full survey. These details are enough to start:

  • The asbestos register, for older buildings
  • The product your specification calls for
  • A wide shot and a close-up of the area
  • Drawings or a marked-up plan, if available

The quickest route to a quote is a few photos and the site postcode. Send them through the quote form, or speak to us on 01277 525 020 or send details through our quote form if you’d rather talk the job through.

Diagnose, treat, sign off

Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. Where we can, we combine work around Longcroft with other jobs nearby, to make the most of each trip. Tell us how flexible your dates are.

  1. First the joints are inspected, widths measured and the type of failure noted.
  2. A fixed quote names the sealant we propose and its movement class.
  3. Phasing is agreed so decks, floors or entrances can stay in use where needed.
  4. The failed seal is cut out and both joint faces cleaned back to sound material.
  5. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
  6. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

What we need from you

  • Share your working hours and any access restrictions
  • Share the asbestos register for older buildings
  • Point out parking and an unloading spot

Getting a fixed quote

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to call the office on 01277 525 020 or email drawings and photos with what you know.

What the job involves on each surface

Car park decks and ramps

Water coming through deck joints is the usual first sign. We strip the old seal, prepare the edges and seal again, and we’ll tell you if any edges need repairing first.

Internal floor movement joints

Forklift and pallet-truck wheels break unsupported joint edges. We match the product to the traffic and the movement.

Maintenance after handover

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:

  • Check joints after long freezing spells
  • Report split or peeling joint sealant early
  • Keep stones and debris out of open joint lines
  • Include every elevation and deck joint in periodic inspections

Our workmanship on movement joints carries a 12-month guarantee. Keep the handover details, product and date with your O&M records, so the next reseal starts with the facts.

Floor joints with failed fillers break up quickly under wheels. Broken arrises jolt trucks, loads and drivers and the broken length grows with every pass. Sealing early protects the edges.

Site staff or a sealant specialist?

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Do you need expansion joint sealing in Longcroft?

The edges of the material can fail rather than the sealant. If the edge of the joint is friable, the bond fails with it.

What tends to prompt an enquiry:

  • Water dripping through deck or ramp joints
  • Expansion joints split through the centre of the bead
  • Brittle, chalky sealant on external joints
  • Expansion joints filled with dirt and stones

Schools such as Denny High School have movement joints in their walls and floors that are easy to overlook.

What your quote should include

  • Whether primer will be used where the manufacturer specifies it
  • Can the work be phased to keep areas open?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Will failed sealant be removed rather than covered?

Questions about Longcroft

Is Chattan Industrial Estate, near Longcroft, within your area?

Yes, sites like Chattan Industrial Estate are within our area, along with the rest of Longcroft. A few photos and the unit address let us price the work.

Is Longcroft too small for you to travel to?

Not at all. Longcroft is within our area. Every Scottish council area is within our area. Where we can, we group nearby jobs to make the most of each trip.

How long will the new sealant last?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

Can staff carry on working while you’re here?

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

How long will the joint resealing take?

That depends on joint lengths, widths, access and how much old sealant or filler needs removing. Typically it takes a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints.

Can you seal joints in cold or wet weather?

The joint has to be dry, and the air and surface temperature inside the product’s limits. Frost, rain and condensation on steel or concrete can hold up external work.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and we will price the work to it.
