Custom Ductwork Design & Installation in {{City}}, {{State}}

Duct sealing repairs existing ducts by finding and sealing leaks with mastic sealant. It's cost-effective if your ducts are structurally sound but have minor leaks. Duct replacement removes old, damaged, or undersized ductwork and installs new custom ducts. If your ducts are severely damaged, crushed, or undersized for a new furnace, replacement is the better long-term investment and will give you better comfort and efficiency.

For most homes, installation takes 2–4 days depending on the scope. A basic duct sealing job might be one day. A full replacement in a larger home could take a week. We'll give you an exact timeline in your estimate. We coordinate around your schedule and ensure minimal disruption to your home.

Savings depend on how much leakage your current ducts have. If you're losing 30% of your conditioned air (EPA average), sealing or replacing ducts can cut those losses to 5–10%, saving 15–25% on heating and cooling costs. A typical homeowner saves $30–80 per month, which adds up to $360–960 per year. A new ductwork system pays for itself in 3–5 years through energy savings alone, plus you gain comfort improvements immediately.

We primarily use sheet metal (galvanized steel) for main runs because it's durable, doesn't flex or crush like flex duct, and provides better airflow. For certain applications, we use high-quality insulated flex duct. We never mix materials haphazardly. Every installation is designed specifically for your home and use case to maximize efficiency and durability.

Yes, but it's a more involved project. If you're switching from a boiler or baseboard heating or from ductless mini-splits, we'll design a new duct system, route it through your home (often through crawlspace or attic), and connect it to a new furnace or heat pump. We assess your home's structure to find the best routing. It's feasible in most homes but requires careful planning and custom fabrication.

Properly installed sheet metal ductwork lasts 20+ years with minimal maintenance. Flex duct typically lasts 10–15 years before insulation deteriorates and kinks develop. Unsealed or damaged ducts should be repaired or replaced as soon as problems are identified to prevent ongoing energy waste. We design systems built to last and back them with a 10-year warranty.

Absolutely. Sealed ducts prevent unconditioned air (which carries dust, mold spores, and allergens) from being drawn into your system from crawlspaces and attics. Properly insulated ducts prevent moisture buildup and condensation in our humid PNW climate. Combined with a high-quality furnace filter, sealed ducts significantly reduce allergens and improve indoor air quality for your family.

We use R-8 fiberglass wrap insulation on all ductwork, which is the standard for residential systems in our climate. R-8 provides excellent thermal protection, prevents heat loss in winter and heat gain in summer, and minimizes condensation risk in our damp crawlspaces. Some applications may call for higher R-values, which we'll discuss in your design.

Most jurisdictions require permits for new ductwork installation and replacement. We handle all permitting and coordinate with your local building inspector. Your installation will be code-compliant and documented. Permits protect you and ensure your system meets current safety and efficiency standards.
