Ductwork Services We Provide
Our licensed and insured technicians handle the full range of duct system work for both residential and commercial properties. Whether you’re building a new system, replacing deteriorated duct runs, or tracking down where conditioned air is escaping, we have the service to match.
- Duct Installation: We install complete duct systems for new construction, additions, and full replacements. When existing ductwork has deteriorated beyond repair or is incompatible with a new HVAC system, we design and install a replacement system sized to your space.
- Duct Repair: Leaking seams, disconnected sections at registers or plenums, and crushed or kinked flex runs all reduce airflow and drive up energy costs. We locate the problem and repair it directly, helping restore your system’s performance.
- Duct Sealing: Conditioned air escaping into attics, crawlspaces, or wall cavities is wasted energy. Sealing those gaps helps keep your heating and cooling where it belongs, improving comfort throughout the building.
- Custom Sheet Metal Fabrication: When standard fittings don’t meet your system’s requirements, we fabricate custom ductwork and sheet metal components using high-grade materials, sized and shaped to fit your specific installation.
Signs Your Ductwork Needs Attention
Some duct problems are visible. Others show up as comfort or billing issues before you ever see the damage. Common indicators that it’s time for a professional inspection include:
- Uneven heating or cooling from room to room
- Unexplained increases in heating or cooling bills
- Weak airflow from registers or vents
- Musty or stale odors when the system runs
- Visible sagging, gaps, or damage to duct sections
New England’s seasonal temperature swings put steady demand on duct systems year-round. Joints and seals wear faster under that cycle of heat and humidity. Older homes in southern New Hampshire often have original ductwork that has developed leaks, corrosion, or insulation breakdown over decades of use.
One Provider for Ductwork & Every Trade It Touches
Ductwork problems don’t always stay contained to the duct system. A damaged run near an electrical chase, a repair that requires plumbing access, or an HVAC component tied to the same comfort issue usually means coordinating multiple contractors. With Cornerstone Services, it doesn’t. Our single-provider model covers ductwork alongside electrical, plumbing, HVAC, cleaning, and handyman services, all under one warranty and one pricing structure.
Every job we complete is backed by a signed workmanship warranty under our quality assurance policy. We price by the job, not the hour, so the number we quote you is the number you pay at completion. No adjustments, no hourly overruns, no surprises. Every technician we send to your property is licensed, insured, and has passed a background check before arrival.
More than 1,250 five-star reviews across Google, HomeAdvisor, Facebook, and Yelp reflect what that model produces in practice. Our service vehicles are staged from multiple locations to support on-time arrival, and our technicians clean up completely before leaving the job site. Financing options are available, and we run monthly promotions that can reduce costs on scheduled services.
Frequently Asked Questions
How do I know whether to repair or replace my ductwork?
It depends on how widespread the damage is and how old the system is. Isolated leaks at a joint or seam are usually repairable. Widespread deterioration, failed insulation throughout, or ductwork that’s incompatible with a new system typically calls for replacement. A professional inspection can tell you which situation you’re dealing with before any work begins.
Is duct sealing different from duct repair?
Yes. Sealing closes gaps and leaks in otherwise structurally sound ductwork to keep conditioned air from escaping. Repair addresses physical damage, disconnected sections, or collapsed runs. Many systems benefit from both, but they’re separate scopes of work.
How disruptive is a duct repair job?
Most duct repairs are straightforward when the ductwork runs through a basement, attic, or crawlspace. Accessible sections can often be reached and corrected without opening walls. We can let you know during the inspection if anything more involved is required.
Do you serve commercial properties in Salem, NH?
Yes. We handle ductwork installation, repair, and sealing for commercial properties throughout Salem and the surrounding southern New Hampshire and northern Massachusetts service area. Per-job pricing and our signed workmanship warranty apply to commercial work just as they do to residential jobs.
