Home Builder

“Can my current sealing methods cost-effectively meet the increasingly tighter duct leakage requirements for new home construction?” That’s a question that many Rochester-area home builders are asking as energy codes for duct leakage continue to tighten, seemingly year after year.

No Mastic copyMany are finding that traditional, manual methods of sealing – metal tape and/or mastic – can no longer reliably meet these codes. Even when they do, it often requires extraordinary efforts which translate to higher costs. Builders have told us that it’s costing them $1000 or more to manually seal… and, even then, they can’t be certain that they’ll meet code.

 

Using state-of-the-art Aeroseal® technology on properly constructed duct work, we guarantee that we’ll meet the rough-in specification of 4cfm per 100 square feet of conditioned floor area.  You’ll receive a Certificate of Completion that will often be accepted by the code enforcer.  Aesthetically, it will look much more professional. And we’ll do it at a price that’s usually less than what you’re paying for manual sealing.

Why not reduce your costs and eliminate the uncertainty?

Construction Requirements:

During the Aerosealing process, pressure inside the duct system may approach 600Pa (2.4” w.c.).  This may place additional requirements on the duct work construction:

  • All connections must be attached with mechanical fasteners (to prevent separation during the sealing process)
  • Any plenum widths greater than 18 inches must be reinforced with a 1”x 1” angle or bar lock (to prevent buckling)

Of course, there cannot be any major holes or gaps.  Aeroseal® will effectively seal leaks up to 5/8”.

Site Requirements:

To ensure you the lowest price possible, we have a few other requirements:

  • At least two separate 20A electrical outlets within fifty (50) feet of plenums in order to power our equipment
  • Clear access to all register openings, including all grilles removed (or not yet installed)
  • Duct work fully constructed, including return air drop and installed buffalo boot
  • Air handling unit not yet installed
  • Drive-up access for our 24-foot trailer
  • Windows and doors easily opened in order to ventilate and dissipate any overspray

We can often still do the job if one or more of these are not met; it just may cost you a little more.

In addition, if you can schedule us to seal the ducts in more than one home a day on adjacent or nearby sites, we can usually reduce our costs and pass those savings along to you.
