Home Performance Evaluation & Energy Assessments

Blower Door 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 Twin Cities & Western WIsconsin 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:

"We had a free inspection of our attic insulation by Logan. He said our insulation was just fine and would not recommend any work be done on it. So great to have an honest contractor who does not want to push product. Thank you for your honesty!"

"Tyler with Lindus did an amazing job of looking over my home and identifying some critical areas of need regarding insulation. I’ve spent my whole career in the trades and always enjoy learning new things and I definitely learned from Tyler. If you’re looking for honest and insightful help with insulation issues with your home, I would highly recommend Tyler at Lindus."

"Tyler was professional in his assessment of our house condition and did a great job explaining my options all without overselling. It turned out for my situation I did not need to book a big project.  Thank you all for being real about what is needed rather than trying to sell me something that I did not need."

"Brian came out to check the attic insulation in our home that we recently purchased. His opinion was we were up to par and code, but we could always use more. The consensus was we would go through our first winter and see how the heat bills were. Thanks to Brian and Lindus for your free analysis of our home."

"My house is 30 years old, and I've never had my attic insulation evaluated. I felt I was overdue to get an inspection and I contacted Lindus Construction via their website. I received a call in a matter of minutes to schedule an inspection. A few days later, Kevin came out and conducted a thorough inspection. The good news was that I had adequate insulation and there was no need to add any more. The bad news was that he identified some mouse activity that I will need to address. Highly recommended contractor!"
