"I could not be more impressed with Jesse and his team. They were so responsive, so professional, and so incredibly helpful. Great communication throughout. Great work product. Pricing that was very competative and reasonable. The next time I have an insulation need I won't even both to get bids from other shops. I will just use Century. Highly recomend."

"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."

"Mark and his crew showed up on time (Friday morning) to perform the work. They initially laid down pads and painters sheets since blowing in cellulose insulation can get quite dusty/messy. They performed the work exactly as described in the bid. Insulating my attic to R60 (up from what it was of R12-15) and filled in all the joists, etc. They even build a wooden platform around an air handler in the attic so it can still be maintained with ease. One of Mark's co-worker spent most of the time in the basement fixing the frozen pipe issue. He applied insulation and sealant in a crawl space near the main water line and reseated an air vent behind the wall, while applying more insulation. He even went to a local hardware store and procured a vent to cover up a hole in the wall we wanted to leave exposed so warm air can flow through (didn't even ask or think to charge me for the vent). The job lasted about 6 hours (which was exactly what Mark quoted). They cleaned up with a shop vac so the house looked very clean when they left.
All in all, was very pleased with the professionalism, knowledge and service provided by Mark and his crew. I proudly displayed a sign in my front yard advertising his services to others and would recommend him to family/friends.

"Great, I could not find anyone willing to do this for us. Mark was running a little behind but had the courtesy to call and let me know that. He worked past 5pm to get the project done for us. Instead of running the cable on the outside of the house like others recommended, he ran the cable up a cold air return to the attic and then over to the bedroom. Along the way, he also gave us useful tips and tricks with the furnace, insulation and took a look at some other work will need in the future. He was clean, professional, friendly and honest."

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

Old insulation should be removed when it shows damage, contamination, or heavy deterioration. If you notice water stains, rodent droppings, mold, or large gaps, plan on taking it out to protect your home’s energy performance and indoor air quality. Removing compromised material eliminates health hazards, cuts energy loss, and sets the stage for a safer, more efficient attic—all while keeping utility bills in check.
R-value measures how well insulation resists heat flow—the higher the number, the better it slows heat transfer. The right R-value keeps your home warmer in winter and cooler in summer, saving energy year-round. Match the rating to your climate zone and have a pro verify performance over time, because moisture or settling can lower R-value and cut efficiency.
Attic insulation can stay in place for 80 to 100 years, but its performance often drops after the first 15. As dust, moisture, or mold build up, the material loses R-value and allows heat to escape. Schedule periodic inspections so a pro can tell you when replacement makes sense—helping you keep energy bills down and indoor comfort up.
You can over-insulate an attic. Beyond the recommended R-value, extra layers don’t add efficiency and can trap moisture, leading to mold or reduced performance. A local insulation pro can measure current levels, confirm the right target for your climate, and advise on any adjustments so you avoid future energy or maintenance headaches.
Insulation can be damaged by mold, pests, water leaks, or accidental electrical contact. When the material is compromised, it loses R-value and can introduce health hazards. Removing and replacing affected sections restores efficiency, while routine inspections from a qualified pro help you catch problems early and keep your attic safe and energy-smart.
