"Not only was Teresa professional and knowledgeable, informing me of the details of the tests and recommendations for what fixes can easily be done myself or with simple fixes. But gave detailed notes of affordable and recommended options for more involved fixes. Additionally, Teresa accommodated my disability well, and discovered two minor gas leaks, aiding me in calling the utility and getting immediate repairs. I'd highly recommend 5 lakes to anyone looking to improve their home energy use, or prevent airflow problems."

We are a full service high performance insulation company. We also perform home performance audits that include infiltration testing and infrared imaging.

"Lee's team of insulation specialists did a phenomenal job of spray foam insulating a very, very small crawl space in our home (as well as some boxsills). We have had several construction professionals in our home recently, as we are considering a major renovation to our house, and they have all commented on how well done the job is, and how amazed they are that insulation specialists were able to access such a small space. The team arrived on time, did their work quickly, and the administrative team was very communicative, personable, and kind. We'd highly recommend Duerst to others!"

TDS Custom Construction specializes in custom remodeling and design in the greater Madison area. We are recognized for our strong emphasis on energy efficient and sustainable designs, and a commonsense approach to home performance and green building techniques. TDS is a full-service design-build contractor that employees 15 community members and has been in business since 1985.

"TDS provided excellent quality and service from start to finish. They removed the old brick chimney that was between the kitchen and dining room, and they did such an excellent job containing the demo debris that I didn’t even have to dust after! They also protected our existing flooring very well. You also can’t even see the patching on the ceiling. And at the end of the job, the PM let us know of a couple other issues he spotted in the attic (replacing vents) but didn’t pressure us in any way to sign them on for another project. I highly recommend them!"

Energy Efficiency Auditing questions, answered by experts

The extra insulation helps reduce energy costs by minimizing drafts and temperature exchange between indoors and outdoors.

ENERGY STAR®-certified windows are the most energy-efficient windows on the market. This certification means that the window meets strict efficiency guidelines set forth by the Environmental Protection Agency. While they might cost more upfront, they can save you money on your energy bills in the long run. ENERGY STAR®-certified windows lower household energy bills by an average of 12% annually.

While parts of the appraisal are out of your control, there are some things you can do to potentially raise the home’s value. You can make necessary repairs and upgrades before the appraiser visits—an appraiser can only value what is currently part of the home, not its potential. You can also provide the appraiser with the cost of recent upgrades. The appraiser will likely increase the value of your home by about 50% or more of what you paid for those improvements.

A couple of the best ways to find a reputable energy auditor is by determining whether they are HEP-certified by the Building Performance Institute (BPI). This certification will help you narrow down your list of professionals to the most qualified pros with the most relevant experience. 

You can also choose from the Department of Energy’s certified list of energy auditors or Angi’s contractor licensing tool to find pros in your area.

While you can perform many routine home maintenance jobs yourself, it’s often a good idea to bring pros in for certain tasks. HVAC maintenance, fireplace and chimney inspections, foundation repairs, and roof inspections and repairs should be handled by professionals who know what to look for and can safely perform repairs. You may also find it helpful to hire a local house cleaning service to help with deep cleaning.
