Why Choose Aviation Mechanical for Your Metal Fabrication Needs

Armstrong ProTeam Expertise

Our certified technicians combine training in HVAC installation and system design with hands-on metal fabrication skills. Every piece is engineered to match your specific equipment, ductwork configuration, and space constraints, ensuring airtight seals and proper airflow.

  • Precision Measurements & Exact Fit

    We take on-site measurements and test-fit components before final fabrication. Custom ductwork that doesn’t fit wastes time and money; we fabricate to your space, not to a standard template, so every run connects perfectly and performs exactly as designed.

  • Chimney Toppers & Chase Flashing Done Right

    Improperly installed flashing around chimneys causes leaks and draft problems. Our technicians fabricate and install toppers and chasers that deflect weather, maintain draft, and complement your roofline. We handle the critical seal between your chimney and roof structure.

  • Local Saskatoon Team Close to Home

    For on-site fabrication and repairs, we’re close by. For custom sheet metal pieces, we fabricate in-house without the delays of mail-order parts. As a locally rooted contractor, we understand Saskatoon’s climate and building codes. Learn more about our company.

  • Integrated HVAC Knowledge

    Most sheet metal shops work in isolation; we don’t. Our fabrication team works alongside our HVAC technicians, so every custom piece fits your heating, cooling, or ventilation system perfectly. No guesswork, no gaps, no retrofit costs.

  • Fair Pricing & No Hidden Costs

    We provide detailed quotes upfront and explain exactly what’s included: materials, labor, precision cuts, and installation. Custom fabrication is not off-the-shelf pricing, but we keep costs transparent and competitive. Financing is available through Finance It.

Know the Symptoms

Signs You Need Custom Fabrication Services

Poor Airflow in Renovated Spaces

If you’ve renovated your home and your HVAC system feels weak or uneven, the ductwork may not fit the new layout. Custom ductwork adapts your system to your space instead of forcing the system into an undersized or poorly routed run. Uneven temperatures, weak registers, and audible whistling are all signs that standard ductwork won’t work.

Chimney Chase Leaks or Draft Issues

Water stains near your fireplace, draft problems, or visible gaps around the chimney base point to failed flashing. A leaking chase or improper topper lets rain in and heat escape. We fabricate custom flashing and toppers that seal your chimney to the roof and maintain proper draft.

Unusual Equipment Installation Needs

Adding a mini-split, upgrading to a heat pump, or installing a heat recovery ventilator sometimes requires custom metal work. Standard connections may not match your existing space or equipment layout. We fabricate adapters, transition pieces, and protective enclosures on-site.

Retrofit Installation Around Obstacles

Renovations often create odd angles, tight spaces, and unforeseen obstacles. Rather than running ductwork inefficiently around them, we design and fabricate custom pieces that fit the actual space. Custom bends and junctions solve problems that off-the-shelf ductwork cannot.

Missing or Damaged Metal Components

If a damper housing is corroded, a junction is damaged, or you’re missing protective flashing, we fabricate replacement parts. New fabrication costs less than replacing entire sections of ductwork and can be completed in days, not weeks.

Industrial or Commercial HVAC Projects

New construction, commercial additions, or specialized spaces (shops, studios, warehouses) often need custom sheet metal. We work with contractors and facility managers to fabricate components that meet codes and match system specifications exactly.

Sweating Ducts and Condensation in Unconditioned Spaces

Bare single-wall duct running through an attic, crawlspace, or unheated garage often sweats when warm supply air meets cold metal, and that moisture drips onto framing, insulation, and finishes. If you see rust streaks on a duct exterior, damp insulation, or water staining below a run, the ductwork likely needs to be re-sealed and insulated rather than simply mopped up. Where condensation is the issue, we fabricate insulated or double-wall sections and seal every joint so the metal surface no longer drops below the dew point.

Our Process

Our Custom Fabrication Process at Aviation Mechanical

Site Assessment & Measurement

We visit your location to understand your ductwork layout, equipment, and space constraints. We take precise measurements, photograph the area, and identify any obstacles or unusual angles that affect the design. This step ensures every piece we fabricate fits perfectly the first time.

  • Detailed on-site inspection of existing ductwork and space
  • Precise measurements of all dimensions and angles
  • Assessment of existing equipment and connection points
  • Documentation of airflow requirements and access limitations
  • Discussion of timeline, budget, and special requirements

Design & Fabrication Plan

Using your measurements and HVAC system specs, we design the custom piece and create a fabrication plan. For chimney work, we assess roof pitch and flashing integration. For ductwork, we calculate the optimal path that minimizes bends and maintains airflow. We confirm the design with you before fabrication begins.

  • CAD layout or detailed sketch of the custom component
  • Material selection (galvanized steel, aluminum, or stainless steel)
  • Assessment of airflow, sizing, and efficiency impacts
  • Review of building code requirements
  • Confirmation of timeline and cost before work begins

Precision Fabrication

Our equipment and techniques allow us to cut, bend, and assemble custom sheet metal to exact specifications. For ductwork, we choose the seam and joint type to match the run, then seal every connection so it holds under working static pressure. For chimneys and flashing, we fabricate with proper overlaps and drains. Every piece is finished to prevent rust and ensure durability.

  • CNC cutting for straight edges and complex curves
  • Rolling and bending equipment for precise angles and diameters
  • Pittsburgh lock and snap-lock seams on rectangular duct for a tight, rigid corner
  • Drive cleats and S-cleats to join duct sections squarely and support the run
  • Gauge selection matched to duct size and static pressure so panels resist flexing and “oil-canning”
  • Mastic on interior joints and code-approved foil tape on exterior seams, rather than cloth duct tape that dries out and fails
  • Surface preparation and finish (paint, galvanizing, or coating)
  • Final inspection and quality check before delivery

Fit Test & On-Site Adjustment

Before final installation, we test-fit the piece on-site. If adjustments are needed, we make them immediately in our shop or at your location. This step catches fit issues before installation begins and ensures a seamless connection to existing components.

  • On-site fit verification and alignment check
  • Minor adjustments or refitting if needed
  • Connection compatibility with existing ductwork or equipment
  • Final approval before installation or handoff
  • Photo documentation of fit and clearances

Installation & Integration

We install the custom piece, seal all joints, and integrate it with your HVAC system. For ductwork, we test airflow and verify balanced performance. For chimneys, we seal the flashing, test draft, and ensure weather protection. You receive a walkthrough explaining the new component and any maintenance needs.

  • Professional installation of the custom component
  • Sealing and insulation as needed for efficiency
  • System testing and performance verification
  • Documentation of installation and specifications
  • Cleanup and removal of old materials
  • Written summary of work completed and warranty coverage

Questions

Frequently Asked Questions About Sheet Metal Fabrication

Most on-site fabrication projects take 1–3 days from measurement to installation. For complex pieces or larger projects, allow 5–7 business days for design, fabrication, and installation. We prioritize your project and keep you updated throughout.

Galvanized steel is our standard for ductwork—it resists rust, seals tightly, and lasts 20+ years. For chimney flashing and exterior work, we use galvanized steel or stainless steel for maximum corrosion resistance. We’ll recommend the best material for your application and climate.

Yes. Ductwork that fits your space properly reduces friction, minimizes bends, and maintains airflow. The result is better heating/cooling distribution, lower energy costs, and less strain on your equipment. A well-designed custom run can improve efficiency noticeably over undersized or poorly routed standard ductwork.

We fabricate toppers and flashing for masonry, metal, and composite chimneys. We assess your roof pitch, chimney type, and existing conditions to design a topper that sheds water, maintains draft, and lasts decades. If your chimney is unusual, we design around it.

Absolutely. If you’re upgrading to a heat pump, adding a mini-split, or installing an HRV, we fabricate adapters and transition pieces that integrate your new equipment with existing ducts. This saves the cost of rerouting entire sections and speeds up installation.

We test-fit on-site before final installation and make adjustments as needed. Our precision measurement and fabrication process catches fit issues early. If a problem arises during installation, we adjust or refabricate immediately at no additional cost.

Yes. All custom fabrication is covered by our workmanship guarantee. Materials carry manufacturer warranties. We stand behind every piece we fabricate and install.

Yes. We work with contractors and facility managers on new construction, retrofits, and complex installations. We understand commercial building codes, equipment specs, and tight timelines. Contact us to discuss your project scope.

Custom fabrication is priced per project based on materials, complexity, and labor. We provide detailed, upfront quotes after measuring your space. There are no hidden costs or surprises. Contact us for a quote.
