This was a unique job. The first time we ever insulated a swimming pool. We are happy the owners are enjoying the results.

Drivers from across the globe give desert racing a try in the Baja 1000 01/17/2024

Cool news feature involving Contractor Nation founder Larry Janesky. Larry started Dr. Energy Saver which is our Comfenergy service and home performance sales platform along with the Basement Systems brand. Congrats to Larry and his team.

Drivers from across the globe give desert racing a try in the Baja 1000 The Baja 1000 is the oldest and most prestigious desert race in the world — and maybe the most dangerous. Teams and drivers try to prove their speed and resilience on the Baja Peninsula. CBS News' Jeff Glor has more, including his own taste of the trek.

With today’s snow, make sure and take a look at your roof. If you can see the roof or lines from the framing, that means you have uncontrolled air loss and are “leaking” conditioned hot air into your attic. This leads to high energy bills and is a great indicator of why your home may be uncomfortable. A well insulated and air sealed home will have snow on the roof and no lines.
