Expansion joint sealing in Riverside of Blairs

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

How the job changes by 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 flagging broken edges along the way.

Brickwork and blockwork joints

Masonry faces are often porous, dusty or crumbly. We clean them back to sound material and prime where the manufacturer specifies.

Expansion joint sealing in Riverside of Blairs

Buildings and slabs are never completely still: temperature, moisture, shrinkage and loading all make materials grow and shrink. Expansion and movement joints are built in so the structure can move without cracking and the seal across each one keeps out water and grit. We seal and reseal movement joints in walls, panels, decks and floors. We work on blockwork control joints, brickwork movement joints and cladding panel joints, and the usual reasons a site gets in touch are expansion joints split through the centre of the bead and joints packed with grit and debris. Looking for mastic applicators who cover Riverside of Blairs? We’ve been sealing commercial buildings since 2005.

Travel to smaller places like Riverside of Blairs is planned so the work is done in one trip where possible. Photos, approximate widths and what uses the floor help us bring the right materials.

We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

After the work

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

  • Check joints after long freezing spells
  • Sweep decks, ramps and floors so grit doesn’t collect in the joints
  • Keep scrapers and ploughs from dragging across joint sealant
  • Note which joints were done, when, and with what

Add every elevation, deck and floor joint to your inspection round. Early splits and edges starting to lift show up on a routine check, when they’re still cheap to deal with. If anything looks wrong, call the office on 01277 525 020 or email drawings and photos with photos.

On a multi-storey car park, a failed joint usually shows up as a leak onto the deck underneath. Salty water dripping through stains soffits and lands on parked vehicles, which is bad news for the concrete and the people parking below. Sealing the joint promptly stops it at source.

Common questions from Riverside of Blairs clients

Is Riverside of Blairs off your patch?

No. Small places get the same service as large ones. Every Scottish council area is within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Would you work within a site like Woodend Hospital?

Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.

How do I request a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.

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. Removing asbestos is a job for asbestos specialists, not us.

What timescale should we allow for resealing expansion joints?

It typically takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing. We confirm the timescale with the quote, including any phasing.

What exactly is a movement joint?

It’s a deliberate gap that lets the structure move without cracking. Expansion joint is a name often used for the same thing, and either way it needs a sound seal.

Can you work to our specification?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.

Owners, agents and contractors

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

How a job runs

Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. Where we can, we combine work around Riverside of Blairs with other jobs nearby, to make the most of each trip. Tell us how flexible your dates are.

  1. We assess the joints on site or from photos, noting widths and how each has failed.
  2. You receive a fixed quote stating the product and the movement it is rated for.
  3. Where areas have to stay open, we agree a phased sequence before starting.
  4. The failed seal is cut out and both joint faces cleaned back to sound material.
  5. Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
  6. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

Getting the site ready

  • Make sure the joints can be reached
  • Tell us your opening times and when work is allowed
  • Point out parking and an unloading spot

Site staff or a sealant specialist?

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

What we can’t put right

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

  • Movement on a scale no sealant is meant to absorb
  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
  • Leaks coming from the membrane rather than the joint seal

If in doubt, ring 01277 525 020 or email drawings and photos and we will say what we think before you book.
