Stock fittings assume a standard building, but very few buildings are standard, and that gap is where many airflow problems begin.

We run our own sheet metal shop, so a duct run is fabricated to the space available rather than assembled from whichever stock elbows come closest to fitting. Fewer joints and turns mean less resistance, and a system that moves the air it was rated for.

Having our own shop also saves time. A transition for a new furnace cabinet or a custom plenum for an awkward closet is made here rather than ordered and waited for. On a commercial job where the business is open, that can make all the difference.

We take on residential and commercial work, from new fabrication to modifications of existing ductwork.

At a glance

Made in our Church Hill shop

The ductwork we make is installed by the same crew that made it.

Duct runs and plenums
Fabricated to the space available, instead of pieced together from stock elbows.
Transitions
A new unit almost never matches the old opening. The transition is made here instead of ordered and waited for.
Existing ductwork
Modified as readily as new work — adding return air, resizing a starved trunk, replacing crushed flex with hard pipe.
Why it matters
Every unnecessary elbow, reducer and flex-duct sag adds resistance, and resistance costs airflow.
How it works

From our shop to your ductwork

  1. Made to the space

    Each duct run is fabricated to the space available, not assembled from stock elbows.

  2. Made in our shop

    Plenums, transitions and duct runs are fabricated here, so there is no waiting on an order.

  3. Fitted by the same crew

    The crew who fabricate your ductwork are the crew who install it.

  4. Air where it should go

    With less resistance in the run, the system delivers the airflow it was designed for.

Why it matters

Stock fittings or ductwork made to fit

Every unnecessary elbow, reducer and flex-duct sag adds resistance, and resistance costs airflow.

A duct run assembled from stock fittings: four elbows, a reducer and a sagging flex section on the way around a beam, with the airflow weakening at each joint.
Assembled from stock fittings Built from whichever stock elbows come closest to fitting, with more joints, more turns and more resistance.
The same run fabricated to the space: one smooth offset under the beam, two joints, and full airflow at the register.
Fabricated to the space One smooth run with fewer joints and turns, so the air reaches the register at full strength.

Common questions

Before you book

Why does custom ductwork matter?

Because every unnecessary elbow, reducer and flex-duct sag adds resistance, and resistance costs airflow. A system starved of airflow is less efficient, less comfortable, and harder on its own components. Fabricating to the space removes those compromises.

Can you make a part for another contractor’s job?

Please ask. Our own installation schedule comes first, but we can often help. Call the shop and describe what you need.

Do you modify existing ductwork or only make new?

Both. Many of our jobs involve correcting an existing system: adding return air, resizing a starved trunk, replacing crushed flex with hard pipe.
