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

If you install LED bulbs, they will use much less energy than incandescent bulbs. LED light strips also use less power. Battery-operated puck lights use no electricity at all, but you will need to replace the batteries as needed. They are beneficial if your power goes out, too, as they will remain on as a light source. 

Audits typically take 2-4 hours, depending on the property size and energy systems.

The difference between an energy auditor and a home inspector is primarily in the purpose of the inspection. The energy auditor conducts tests in your home to determine the energy efficiency levels in areas like windows, insulation, and doorways. The auditor then makes recommendations for ways to improve a home’s energy efficiency. 

A home inspector examines various structures of your home to determine that everything is up to code and gauge the condition of features like the roof, foundation, HVAC, and electrical. The home inspector reports on the overall home and makes repair recommendations.

Yes, these services often increase home value by preventing moisture-related issues and enhancing the usable space in basements or crawlspaces.

Motion-sensor lights use one watt while on standby and five watts while turned on. They’re usually on for one hour over a 24-hour period, bringing the total wattage to about 28 watts per day. LED lights use around 6.5 to 8 watts while on. If you leave an LED light on all night, with night ranging from 10 to 14 hours, you’re looking at using 65 to 112 watts a night. You can minimally cut your wattage in half by switching to a motion-sensor light.
