Expansion joint sealing in Lennoxtown

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

How a job runs

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access, and our waste is bagged and taken away as we go. For work around Lennoxtown, we aim for one trip, so photos, sizes and a full list matter. External joints need a dry spell as well.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. We compare each joint’s width with the movement and the sealant’s capability.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  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. Areas reopen once cured, and the work carries our 12-month guarantee.

Advice

Expansion joint sealing for commercial buildings in Lennoxtown

Floor movement joints in warehouses, retail and public buildings carry wheeled traffic. Unsupported edges break up under wheels so the product has to suit both the traffic and the movement. If the arrises are already broken, we’ll say so before sealing and phasing can keep areas working. We work on cladding panel joints, car park decks and ramps and blockwork control joints, and the failures we’re asked to look at most are expansion joints filled with dirt and stones and water getting into the wall through a failed joint. Looking for mastic applicators who cover Lennoxtown? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.

Weather windows decide external joint work around a place like Lennoxtown: sealant needs a dry joint and a temperature within its range. Internal floors can be done whenever suits the site.

Surface by surface

Internal floor movement joints

Floor joints include saw-cut joints and construction joints. A semi-rigid filler is common in trafficked industrial floors.

Brickwork and blockwork joints

Masonry faces are often porous, dusty or crumbly. Faces are prepared and primed wherever the sealant maker calls for it, then seal and tool the joint.

Expansion joint sealing around Lennoxtown: how the place shapes the job

The west of Scotland, where Lennoxtown is, gets more rain than the east. Open joints in car parks and yards let in more water than in drier areas. Dry spells are used for the external joints.

For an estate such as Broomhill Hospital, which lies south-east of Lennoxtown, the joints in ramps, decks and long building elevations all need attention over time.

Lennoxtown is about 3 miles north-west of Kirkintilloch, in East Dunbartonshire. Businesses, contractors and managing agents in Lennoxtown use us for work on movement joints, as part of our coverage of East Dunbartonshire. We work across 24 places in East Dunbartonshire, large and small. There’s a separate page for Glasgow, roughly 9 miles from Lennoxtown.

Work on movement joints is covered throughout G66, whatever the building. For a building on Main Street, Station Road and Slatefield or nearby, send details and we’ll quote for movement joints. Main routes into Lennoxtown include the A891, which helps when planning parking and deliveries for the job. We also cover Milton of Campsie (2 miles south-east), Birdston (2 miles south-east), Auchenreoch (3 miles east), Auchinreoch (3 miles south-east) and Kirkintilloch (3 miles south-east). Further afield, our area takes in Bearsden (6 miles south-west), Bishopbriggs (5 miles south), Milngavie (5 miles south-west), Westerton (7 miles south-west), Colston (5 miles south) and Cadder (4 miles south).

Common questions from Lennoxtown clients

Does a site in Lennoxtown have to shut while its joints are sealed?

In the majority of cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. Tell us which hours and entrances we can use and we will plan from there.

Is Lennoxtown too far out for you?

No. Small places get the same service as large ones. Every Scottish council area is within our area. Good photographs up front let us bring everything on the first visit.

Does the weather affect the work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

Can a joint be sealed if the edges are broken?

Broken arrises have to be put right before resealing. A bead on a broken edge soon lets go.

What sealant do you use in movement joints?

It depends on the movement, exposure and traffic. Facades often take a low-modulus silicone; floors and decks normally need a polyurethane.

When can you be on site?

We are in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.

Can staff carry on working while you are here?

Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.

Aftercare for building managers

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

  • Inspect exposed joints once the cold weather has passed
  • Treat a small split as a warning, not a cosmetic issue
  • Keep product details with the building records for the next reseal
  • Put movement joints on the planned maintenance inspection round

In warehouses, forklift and pallet-truck routes take the most wear. Keep racking feet and heavy point loads off joint lines and flag chipped arrises before they spread.

Once debris packs a failed joint, the structure has nowhere to expand. The arrises crack and break away under the load, turning a sealant job into a repair job. Keeping the seal sound avoids all of that.

Do you need expansion joint sealing in Lennoxtown?

Repeated failure often traces back to the wrong product. A stiff or general-purpose sealant across a joint with large movement won’t cope. Movement capability is set out in BS EN ISO 11600.

Look out for the following:

  • Expansion joints filled with dirt and stones
  • Torn sealant in brick or block movement joints
  • Joints where the bead has lost adhesion
  • New sealant over old, now failing

A campus such as University of the West of Scotland (4.9 miles south-east of Lennoxtown) has long runs of movement joint in its buildings, decks and paving.

How to choose a sealant contractor

Owners, agents and contractors

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, and each stage is agreed with your contact.

We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Lennoxtown. Several sites can go on one quote, which keeps the paperwork simple.

When something else is needed

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:

  • Leaks coming from the membrane rather than the joint seal
  • Broken or spalled joint edges, which need repairing before any sealant goes in
  • A joint that has to be widened or re-detailed before it can work

Not sure which it is? You can speak to us on 01277 525 020 or email the details over and we’ll tell you honestly.
