"Bartholomew did very poor work and greatly overcharged for installing a pellet stove, a very simple job. We waited a long time for them to come and do it, although the actual work took a very short time. They did not even plug in the stove or run it to see if it worked properly, and did not complete the required certificate as certified installer to prove the stove was installed to code and operating properly. We just failed the first inspection attempt, as inspector said that information was required to be onsite at time of inspection and Bartholomew knew (or should know) that. Reinspection fee now required, and another long delay to get completion. Bartholomew was very slapdash and unprofessional. I do not recommend them."

"Your home efficiency experts!" We are a construction company providing a wide variety of services including but not limited to: Insulation, Weatherization, Air Sealing, Windows, Doors, Siding, Gutters & Roofing. We also offer an exclusive no-cost, no-obligation Home Energy Assessment once annually to Michigan homeowners residing in our service area.

"We ordered our large front window (including 2 side windows) back in November 1923. They said it would be 6-8 weeks and that was fine with us as Christmas was around the corner. Come January 2024 we hadn’t heard any updates so my husband called them to check the status. They said it hadn’t been delivered yet (built in Ohio). In February, hubby called again and they reported the side windows had but the center one couldn’t be found… . We agreed to go ahead with the side window install mid February. They came and did a nice job, but they had to complete the frame in with new Quarter Round (plain wood color)! They left. The next report : it was coming in end of that week . Didn’t happen. Finally end of February it arrived from warehouse. Today it got installed on March 4th!! In the meantime my husband said for all the mix up in dates and install dates wonder if they would accept a deal? They agreed to paint the new Quarter Round instead of a $50 discount. And we agreed on White to match the Framing on window. The guys who came to finish/complete last install were very curtious and cleaned up after everything was done . We are very pleased with the work they performed and really love the Triple Pane windows. Looking to lower our energy bill as the last windows had no insulation!"

Energy Efficiency Auditing questions, answered by experts

While many states require all new construction to undergo blower door tests, it’s not a requirement for existing homes. But in both cases, a blower test helps confirm that the contractor has sealed the exterior, that the type of ductwork installed is functioning properly, and that your home is as efficient as possible.

There are several strategic ways to lower your home insurance premium. The primary one is to shop around and get quotes every few years to make sure you’re getting the best deal. Also, sometimes bundling your auto and homeowner’s insurance will get you a discount on both. Finally, try to keep your credit score up; many homeowner insurance companies use credit scores to generate quotes.

R-value is calculated by dividing the thickness of an insulation material by its thermal conductivity. The material's composition and density influence thermal conductivity. Materials with lower conductivity values provide better insulation. The higher the R-value, the better the material is at insulating, helping homeowners select insulation that meets the energy needs of their climate and home layout.

Some types of electric fireplaces use more electricity than others. Models that produce 1,500 watts will have more of an effect on your heating bill than 750-watt models. 

Electric fireplaces use an average of $1.85 of electricity every eight hours. These minimal operational costs aren’t likely to make a big difference in your electric bill—unless you’re using it as a primary heating source for your home and it’s running most of the time.

Yes, installing an attic fan can help lower your electric bill—particularly if you live in a hot and humid region. By replacing hot and stuffy air with cooler air, these fans help regulate the temperature in your attic and the rest of your home, taking some of the pressure off of your air conditioner.
