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:

"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!"

"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."

"Lindus Construction has lived up to its promises and more. We had the Insulation in our roof replaced. They showed up on time, completed their work in two days, cleaned up so that you would never believe they had been there. Randall, the Supervisor came often to check on the progress and helped as well.  We would highly recommend this company to anyone considering some type of home remodeling. Grading AAA+."

"We did a major re-insulation which included vacuuming out old insulation, spraying a layer of foam, and blowing in additional insulation. A different crew performed each operation. All did an excellent job. We'd use Lindus again for insulation work, though we hope never to need it again."
