Ductwork Repair and Sealing in Newark, NJ

Ductwork Repair and Sealing in Newark

Equipment in Newark has to cover a wider range than most of the country asks for — hard winter cold at one end and humid stretches in the eighties and nineties at the other. A system sized for the middle of that range disappoints at both ends of it.

About 23% of homes in Newark were built before 1940 — old enough to have been built with radiators and no ductwork at all; 72% of them heat with natural gas, so furnace and boiler work is the bulk of what comes up here. (US Census ACS 2022)

What repair actually involves

Less dramatic than it sounds, and usually a day or two.

Sealing joints properly

Mastic — a brushed-on compound — at every joint, boot and plenum connection. Cloth duct tape, despite the name, dries out and releases within a few years, and finding it hanging off a joint in an attic is routine. Foil tape is acceptable; mastic is better.

Insulating what runs through unconditioned space

A duct crossing a 130-degree attic in July, or a 20-degree crawl space in January, is losing energy through its walls even where it does not leak. Insulating those runs is cheap and immediately effective.

Fixing the flex duct problems

Flexible duct is fine installed properly and terrible installed badly. Sags, sharp bends and compression where it passes a joist all restrict airflow substantially. Supporting and straightening runs is unglamorous work that frequently solves the complaint on its own.

Balancing

Adjusting dampers so each branch gets its intended share. Free, if the dampers exist and someone takes the time.

Repair or replace the ductwork?

Replacement is occasionally right but it is proposed more often than it is warranted.

Repair, usually

Sealing, insulating and rehanging existing ducts addresses most complaints at a fraction of replacement cost, and it is far less disruptive.

Replace where the design is wrong

If the system was extended room by room over decades into additions and finished attics, the trunk may simply be too small for what now hangs off it. No amount of sealing fixes an undersized main. That is a design problem and it needs redesigning.

Ask for both, quoted

A contractor proposing full replacement should be willing to price the repair alternative and explain why it will not do. If they will not, get a second opinion — this is an area where the gap between the two options is large.
