Caulking and Waterproofing Services Sydney | JG Vertical

Leaks spread fast. Repairs shouldn’t drag. At JG Vertical, we offer rope access caulking and waterproofing services in Sydney that keep buildings sealed tight and looking sharp.

We go where ladders can’t. Our crew works high and clean, sealing weak spots that others leave behind. That means fewer delays and better results. Whether you’re dealing with a leaking joint on the 20th floor or patchy seals across an entire facade, we’ve got the gear and the grit to fix it right.

Caulking Services for High-Rise Buildings

Air, water, pests — they all sneak in through the smallest cracks. Caulking blocks them out. It keeps buildings more energy-efficient and helps extend the life of materials that would otherwise wear out too fast.

We seal:

  • Glazing and frames
  • Precast concrete joins
  • Rooftop trims and flashing
  • Expansion gaps
  • External building cracks
  • Brick joints and cladding seams

What we use:

  • Acrylic latex
  • Silicone
  • Polyurethane
  • Fire-rated sealants

We match the product to the problem. That’s how we keep it sealed. We also make sure the old sealant is properly removed and the edges are clean to ensure maximum bond strength.

High-Rise Waterproofing

Sydney weather is wild. Sun one hour. Pouring rain the next.

Our waterproofing helps buildings stand up to it all. It’s not just about leaks. It’s about stopping deterioration before it spreads.

We treat:

  • Concrete walls and panels
  • Glazed windows and mullions
  • Metal and composite cladding
  • External joints
  • Brick facades and parapets

All work is carried out by rope. No scaffolding means we get in fast and get out with less hassle.

Why Invest in Commercial Waterproofing and Caulking Services?

Water damage doesn’t wait. But it leaves signs:

  • Cracks in concrete
  • Loose or discoloured sealant
  • Leaks near windows
  • Damp smells in upper units

We seal things before they turn serious.

You get:

  • A drier, safer building
  • Lower energy bills
  • Fewer mould problems
  • A cleaner facade
  • Longer-lasting surfaces

We also solve:

  • Poor drainage staining the walls
  • Expansion joints shifting out of place
  • Gaps around old window seals

Routine caulking and waterproofing save thousands in long-term repair costs, especially for high-rise buildings.

What Our Process Looks Like

We don’t guess. We check everything.

  1. Site Check: We inspect the building top to bottom. Joints, seals, surfaces.
  2. Clean-Up: Surfaces get cleared of dust, paint flakes, or old product.
  3. Seal It Up: We use the right caulk or membrane. Applied by hand. Spot by spot.
  4. Final Review: We look over every seam. You get the report. We fix what needs fixing.

Photos? No problem. We can send before-and-after shots if needed.

We also provide guidance on how often to reseal or re-inspect, depending on your building’s condition and exposure.

Rope Access, Done Right

We’re not new to this. Our crew is IRATA-certified. They know how to move, anchor, and seal at height. Every member is trained to do the job right — and safely.

We meet the rules. We respect your space. We finish the job without making a scene. We also work around building access hours and occupancy restrictions, so your operations can continue with minimal interference.

    FAQs

    What is caulking?

    Filling cracks and joints with a flexible material to keep water and air out.

    How does weatherproofing help?

    It blocks leaks and stops weather damage. It also helps seal in heating and cooling.

    Can caulking stop mould?

    Yes. Dry walls don’t grow mould. Seal them properly, and moisture stays out.

    What do you use to seal gaps?

    We use caulk or sealant, depending on how much movement the area sees.

    How big a crack can caulk fix?

    Up to 6mm wide. Bigger than that? We add filler first.

    How do you know where leaks are?

    We check around windows, cracks, joints, and stained spots.

    Do I need scaffolding?

    No. Rope access covers most buildings. Faster and cheaper, too.

    Will tenants be disturbed?

    Not much. We don’t block access or leave tools lying around.

    How long does it last?

    5 to 20 years, depending on the sealant and weather. Sun-facing sides wear faster.

    Can I get a quote?

    Of course. Just contact us. We’ll take a look and get back to you.

    Do you offer service reports?

    Yes, and you’ll get photos and recommendations with every job if you request them.

    Can you work after hours?

    We can. For commercial buildings, we offer flexible scheduling options.
