How it works

1

Measure and source

We measure the duct opening size and match it to the correct cover, accounting for face size that overlaps the opening.

2

Remove and clean

We pull the old cover, vacuum debris from the duct neck and clean the surrounding surface.

3

Install and secure

We snap or screw in the new cover, verify it seals against the wall or floor and doesn't rattle.

We can help

Problems we fix

  • Covers painted shut over multiple renovation cycles, blocking the adjustment damper
  • Plastic covers yellowed and brittle with age, cracking when touched
  • The wrong-size cover installed, leaving a visible gap around the duct opening
  • Floor registers lifted by foot traffic and sitting crooked

Good to know

Vent Cover Replacement — FAQ

What size vent cover do I need?

Vent covers are labeled by the duct opening size, not the face size. A 4"×10" cover fits a 4"×10" duct opening — the face overlaps by about an inch on each side. We measure the opening, not the old cover.

Can I get decorative vent covers that match my decor?

Yes. We can install cast-iron, brass, brushed nickel and wood-grained vent covers to match your flooring or hardware style.

Should vent covers be open or closed in unused rooms?

Modern HVAC systems are balanced for all vents open. Closing them can increase duct pressure, reduce efficiency and lead to comfort problems elsewhere.
