Home Performance Evaluation & Energy Assessments

Blower Roof Testing

A blower door uses a powerful fan that we will mount in the frame of one of your exterior doors. The purpose of the fan is to pull air out of your home, which will lower the pressure inside, allowing the outside air pressure to flow through any unsealed cracks and openings that exist in your home. Our trained specialist will walk through your home with a smoke pencil that will allow them to pinpoint your troublesome areas when conducting the energy assessment.

FLIR Thermography Audit To Identify Air Leaks

We use a FLIR Infrared Imager that will take thermographic scans of your home which measure surface temperatures by using infrared video. Using this energy efficiency audit, in conjunction with our blower door testing, will help find air leaks in your home by showing up as black streaks on the infrared imager. This technique can also help detect roof leaks because wet insulation conducts heat faster than dry insulation.


Energy Audit Checklist For Homeowners 

  • If you burn wood in your home, make sure that your fire is completely out. This includes even any coals, before your specialist arrives.
  • Make sure that your attic, crawl space, closets and any unused rooms are easily accessible.
  • All air inlets in your home will need to be closed such as fireplace dampers, doors, windows etc.
  • Fossil fuel appliances will need to be shut down temporarily, so they don’t fire during the test.
  • Be sure to set aside a few hours for the test to allow the technicians to be as thorough as possible.

Our Insulation Services Reviews:

"Lindus Construction has done several projects for us over the years: LeafGuard® Gutters, new roof, new doors, new soffits and facia on the upper level, residing of a portion of the upper level, re-insulation of the attic to help us reduce/eliminate ice dams. They've performed admirably on all of these projects and have been great to work with. We've been pleased with all their work and gladly recommend them to others."

"I was very happy with the free insulation estimate I received from the Lindus rep. He took the time to walk me and my father-in-law through a thermal scan of all the leaky spots in my attic - and basement, bonus! - and was honest and forthright about the work they do and the best and most economical options available to us to improve ambient temperature control in these areas."

"Lindus Construction has been my go-to resource for a number of projects at my home, including gutter installation, window replacement and re-insulation of my attic, a bathroom remodel, and a total remodel of my basement. Each of these projects was planned and executed with the greatest care in conjunction with the specific needs of my property. The quality of the work has been exceptional. Moreover, each of team members have been pleasant in answering any questions l may have had. Lindus truly deserves a 5-star rating!"
