Expansion joint sealing for commercial buildings in Old Blair

Long runs of brick or block have movement joints built in that most people only notice when the sealant has gone. Failed sealant here lets rain into the wall and can leave the joint full of debris. The old seal is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled. Site teams most often ask us about torn sealant in brick or block movement joints and joints packed with grit and debris, on podiums and floor movement joints, brickwork movement joints and cladding panel joints. A single leaking joint is often how a building in Old Blair 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.

In smaller places such as Old Blair, the joints we’re asked about sit in workshops, farm sheds, schools and halls. Slabs and yards take vehicles, rain and frost.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

When it isn’t the sealant

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

  • Structural movement beyond what the joints were designed for (that needs a structural engineer)
  • Crumbling edges that would give a new bead nothing sound to grip
  • 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 email the details over and we will say what we think before you book.

Joints and surfaces we work on

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

Expansion joint sealing around Old Blair: what changes locally

Old Blair is on Scotland’s drier eastern side. Cold winters and gritting are hard on any yard or deck joint left open. Resealing before the cold months helps protect the edges.

A joint near Old Blair that has lost its sealant lets in water and grit, and the edges suffer next. Around Old Blair, each joint gets a filler or sealant matched to what crosses it and how much it moves.

Why it’s worth doing now in Old Blair

Leaving a failed movement joint rarely stays a small problem. Water and debris get in, the joint jams and the edges spall and the job grows to repairs as well as sealing. Resealing early keeps the work to sealant. Exposed buildings in Scotland take a lot of weather, and for a smaller place like Old Blair, a repair visit takes planning, so it’s better to act early.

The price depends on the quantity of joints, what has to come out first and the access. Call for a quote once you have the details.

Different surfaces, different methods

Car park decks and ramps

Deck and ramp joints take tyre loads, grit and de-icing salts. We use a sealant made for wheel loads and the expected movement with bays done in phases so the car park keeps running.

Brickwork and blockwork joints

A brick movement joint full of old mortar or debris can’t close. We clear the joint fully before sealing, and tell you if the joint looks too narrow for the movement.

Old Blair: questions and answers

What documents will you need to give us for a job in Old Blair?

RAMS, insurance certificate, CSCS details: list what the site needs and we’ll confirm it with the quote. We hold £5m public liability insurance, are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded.

Is Old Blair off your patch?

Not at all: smaller places are covered as well as towns. We cover the whole of Scotland. We plan jobs in smaller places so return trips are kept to a minimum.

How long will the new sealant last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

Can a joint be sealed if the edges are broken?

The edges have to be sound. If they’re damaged, we’ll say so before any sealing.

Do you seal on top of existing sealant?

No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

Do you offer coloured sealant?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

What if there’s asbestos in the old mastic?

Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.

Doing it in-house

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

Our process

When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself normally taking a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints. For a building near Old Blair, directions, keys and a contact on the day are worth sorting early. That goes into the plan alongside the quote.

  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. We strip out the old seal and prepare the faces, flagging any broken edges that need repair before sealing.
  4. Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
  5. Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
  6. We check every joint before sign-off, and the work carries our 12-month guarantee.

Getting the site ready

  • Point out any areas we must not close
  • For older buildings, check the asbestos register before work
  • Have the specification and drawings to hand
