"Ryan, Miguel, Luis and staff did a great job removing old insulation, inspect, clean & disinfect, spray foam, and blow in new insulation. They were efficient, kept me informed, cleaned up well, and addressed minor issues after the completion was complete. I had planned to also spray foam the basement, but we could not vacate the house (fumes) with a member in hospice. This will be done as soon as we are able. Highly recommended!"

"Ryan did our estimate, and was very efficient. Andrew and Evan did the insultation work and did a fantastic job! It was a large area to get prepped and then to insulate and they did a great job every step of the way! Our entire home is now at a R50+ insulation level, as opposed to the R25-30 and 0 values we had before. It will be interesting to see what sort of impact the newly insulated garage and 3 season porch has on the comfort level in the main house. The team did a great job for us and I would recommend them to anyone considering insulation!"

"My husband and I somehow have energy bills that are much higher on average than our neighbors according to the energy company. So we're interested in adding insulation to our home and possibly replacing some windows plus two patio doors. Before spending the money, we thought it would be smart to do a home energy audit first to see if it is worth the investment. We are generally comfortable in our home, but it seems we are overpaying to keep it that way.

There are several energy audits offered by Excel, which is what we were initially going to have done. However, my husband was referred by a colleague to Hoffman Weber Construction who had some attic insulation put in his home by the company over the winter. Since they offered free estimates and we heard the work was done well (he told my husband his bills have significantly improved), we scheduled an appointment to them to come out and give us a quote.

A gentleman from the company called to confirm the appointment and my husband asked what they do specifically to know how much insulation is needed. He told him he typically starts with a consultation and asks questions to determine why we believe insulation is needed, then checks for moisture issues and performs and attic inspection. My husband asked about the Excel Energy audit, and the guy mentioned their company is putting together a new service that is very similar and offered us the program for free if we'd allow them to do our inspection as training for some of their reps. We agreed and had them come over yesterday to do everything.

They started with a blower door test which helps determine how much air our home is leaking, which was a shocking amount (81 inches - basically like a big hole in the wall we can't see). One gentleman who seemed to be the most knowledgable of the group showed us how it takes the measurements and explained everything very well. They went around with what looked like speed detection guns, but were used to show infrared. They figured out that our electric fireplace chimney had a significant issue that could be resolved with some insulation. They also showed us how much air each bathroom fan and air duct was actually flowing out compared to what is code. Overall, it was very educational for my husband and I and every person that involved from Hoffman Weber was courteous and respectful. They gave a quote on the insulation and windows, and we are currently looking into financing options. When/if we are able to afford it, we will be delighted to have this company come back out for the actual projects."

Insulation FAQs, answered by experts

Your house may be cold even if the heat is on because of bad insulation, gaps in doors, small holes pulling hot air from the home, or excess humidity. The heater itself might be malfunctioning. For this problem, you’d need to talk to an HVAC pro. If you have a gas heating system (most do) this should be considered an urgent job as natural gas could be leaking in your home.

Bubble wrap is better for moving since it can be cut to size, whereas dish foam comes in precut sheets that are harder to manipulate. However, if you’re packing items like dishes, wine glasses, picture frames, or mirrors, dish foam will protect them better. Ensure you measure your box beforehand so you know what size dish foam to purchase. 

Carriage, sliding, folding, and trackless pivot doors all replace a standard roll-up door. Glass doors and roll-up screens work well when you convert the garage into living space. Match the style to your driveway clearance and climate.

A vapor barrier keeps moisture out of the crawl space, while insulation reduces the amount of unconditioned air—and sometimes moisture—that enters the space. Coupling a vapor barrier with insulation can help prevent humidity and related moisture damage in a crawl space while also making your home more energy-efficient. Just be sure to use insulation that won’t get damaged from moisture, like rigid foam board or expanding spray foam insulation.

Mineral wool wraps are the most affordable and effective insulation for crawl space ducts. They are easy to cut, last for a long time, and healthier for humans. Meanwhile, fiberglass wraps are cheaper but more hazardous and difficult to handle. If you do choose to use a fiberglass wrap, make sure you are wearing long sleeves and wear proper protective gear.
