Expansion joint sealing across Clachamish

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

Expansion joint sealing in Clachamish

Brickwork and blockwork walls have vertical movement joints at intervals, and they’re easy to miss until the sealant fails. 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 with primer where the maker calls for it. We work on car park decks and ramps, podiums and floor movement joints and cladding panel joints, and the failures we’re asked to look at most are joints where the bead has lost adhesion and damp inside where a wall movement joint has failed. Looking for mastic applicators who cover Clachamish? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.

For floor or movement joints around smaller places like Clachamish, we plan to finish in one visit where we can. Send photos, joint widths and details of the traffic first.

The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Signs you need expansion joint sealing in Clachamish

On trafficked joints, wheels and salts do the damage. Wheel loads stress the sealant and the arrises, while grit and salts work into any gap. The product has to be suited to the traffic.

Clients usually get in touch after noticing something like this:

  • Hardened, cracked sealant on exposed facades
  • Movement joints with split or torn sealant
  • Damp inside where a wall movement joint has failed
  • Leaks through car park deck joints onto the level below

A joint near Clachamish that has lost its sealant lets in water and grit, and the edges suffer next; we will tell you if the edges need repairing first.

What your quote should include

  • How the existing material will be dealt with
  • What site paperwork they can supply
  • Can the work be phased to keep areas open?
  • Proof of insurance

Questions about Clachamish

Is Clachamish too far out for you?

No. Places such as Clachamish are covered as much as the big towns. We work across every Scottish council area. We plan jobs in smaller places so return trips are kept to a minimum.

Can being near the sea in Clachamish affect the sealant we need?

It can. Coastal exposure works external joints harder than inland weather. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.

What’s the quickest route to a quote?

The quote form is the simplest route, though you can also speak to us on 01277 525 020 or email drawings and photos. Photos, drawings or a joint schedule help us quote quickly.

What if there’s asbestos in the old mastic?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.

What site paperwork can you supply?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.

Do you need to see the site first?

That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.

How do you choose the sealant?

A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Different surfaces, different methods

Brickwork and blockwork joints

Vertical movement joints in brick and block walls let the masonry grow and shrink. They take a low-modulus sealant with a movement class to suit laid over backing rod at the correct depth.

Cladding panel joints

Cladding panels move more than masonry as they heat and cool. A sealant with the right movement class is chosen in a colour confirmed for that product.

What sealant work can’t fix

Honesty saves time and money. Fresh joints won’t solve:

  • Cracking or settlement that calls for an engineer’s assessment
  • Leaks coming from the membrane rather than the joint seal
  • Proprietary pre-formed expansion joint systems

If in doubt, ring 01277 525 020 or email drawings and photos and we’ll say what we think.

Joints and surfaces we work on

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

Building owners, agents and FMs in Clachamish

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Joints that move: notes for Clachamish

With the shore within about 1 mile, Clachamish counts as a coastal location. Near the sea, external slabs, ramps and decks see salt air and driven rain as well as their usual loads, so a failed joint lets more in and the edges break up sooner. Clachamish is in the west of Scotland, the wetter side of the country. Open joints in car parks and yards let in more water than in drier areas. External sealing is booked for dry spells, with some give in the dates.

Around Clachamish, each joint gets a filler or sealant matched to what crosses it and how much it moves.

What affects the price in Clachamish

Before we quote, we look at:

  • Location, for remote and island sites
  • How accessible the joints are
  • The site’s rules and procedures
  • Joint width, depth and condition

Pricing movement joints depends on how many there are, their condition and the access, plus any specification you are working to. Call for a quote.

What we need to price the job

There’s no need for a formal survey. These details are enough to start:

  • Whether an asbestos survey exists
  • Whether the building will be occupied during the work
  • A wide shot and a close-up of the area
  • Any specification or named product

The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or call 01277 525 020 or send photos by email to discuss it first.

How a job runs

When we get to site, we report to your site contact and complete whatever induction the building runs. 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 Clachamish, directions, keys and a contact on the day are worth sorting early. We will confirm the plan with the fixed quote.

  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 and tell you if the design looks wrong for the movement.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  4. Any broken arrises or friable edges are flagged before work goes further.
  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.

Before we start on site

  • Point out any areas we must not close
  • Confirm the product named in the specification
  • Explain the parking and delivery arrangements
