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:

"I initially thought I needed more attic insulation, but after an inspection by Tyler Durand, it turned out we had enough insulation, but poor ventilation. I replaced clogged eve vents on the west side of my home, and when Randall Bowman installed 6-foot air vent shoots in the attic, he also replaced the eve vents on the east side and added an extra vent. Randall went above and beyond, and I'm grateful for his extra effort. This should help keep more snow on the roof this winter. Overall, I'm highly satisfied and would recommend Lindus to others."

"Highest recommendation for Lindus Construction team. We started with a heat map analysis of our kitchen to address significant cold areas, and transitioned to a solution to insulate the walls and install hot water in floor heat as selected solution. Kitchen was demoed down to the studs to access walls from inside, which allowed for a complete remodel of 1960-70s kitchen. Lindus team provided design expertise, cabinet, flooring and countertop selections, plus drywall, electrical, HVAC and plumbing teams, along with skilled carpenters. Lindus team provided good communication of schedule and handled minor delays that happen with all projects with high customer service. Such a pleasure to work with Lindus Construction! Thank you for a significantly improved kitchen design."

"Mitch did an outstanding job at my home today. He made me feel extremely comfortable. He was extremely thorough. And explained everything down to the down to the bottom detail. I couldn't be more happier. And if I know anybody that needs any work done, I am certainly going to recommend Lindus Construction. So thank you very much."
