"David and his team were very professional and the work they did was excellent---we could tell the difference the next day. The temperature on the 2nd floor is several degree lower than before due to the new insulation and feels much more comfortable. David has solid knowledge regarding insulation and he explains things clearly. Definitely would recommend David and Prudent Homes to my friends and neighbors."

"Comfenergy was very professional thorough from the in-person estimate thru installation. Even though we didnt have a full energy audit, they still go over your entire home and tell you what should and what needs to be done. Some of the little things we did ourselves, or had our handyman. Then Comfenergy did the big part, seal and insulate the attic. We still had late 80's insulation and never a sealing done. It ended up being over an 8 hour project. They were not the cheapest estimate, but definitely the most in-depth review and recommendations provided. The two man team that did the actual work were very professional, showed us the work as the progressed, and good clean up job after all was done."

"We had a great experience with Discount Energy Services. They insulated our entire attic and crawl space, and from start to finish they were professional, responsive, and easy to work with. The turnaround time was impressively quick, the quality of the work was excellent, and we felt the value was very good for the scope of the project. The team was efficient, knowledgeable, and clearly took pride in doing the job well. We really appreciated how smoothly the whole process went and would gladly recommend Discount Energy Services to anyone looking for high-quality insulation work."

"Fantastic experience with Kelvin. Very quick response for an initial estimate. Came out to check it out within a few hours. Also helped me out immensely by doing the job on the weekend which he normally doesn’t do! Definitely highly recommended!"

Company personnel scheduled to do the work on a semi holiday and they arrived on time/when they said they woudl.  They were very attentive to doing a good job - they lined the floor with plastic; they vacuumed up excess insulation).  They even phoned up days after completing the project to inform us that we might be able to take advantage of a tax benefit.  We would definitely recommend this company."

"Technician Howard Shires exceeded my expectations, i.e., not only was my immediate need met, i.e., the roof leak was patched, Mr. Shires calmly walked me through an inspection of the roof inside (attic) and outside, pointing out the additional problems in need of repair, which were essentially masked by my attic insulation. In addition, the repair and inspection were documented with photographs. Lastly, based upon the trust inspired by Mr. Shires' skill and professionalism, I have scheduled a follow-up appointment to get a roof replacement bid. Note, my roof was old when I moved in 20 years ago, and today's inspection and pictures taken by Mr. Shires indicate additional leaks and some questionable patching done before I moved in."

"The initial energy audit took ~4 hours and the technician, Andre was punctual, professional and sat down with me to explain the process at the beginning and end of the audit.
I then met with a manager the following week to review the results of the audit and the proposed services. I was also informed of the state energy rebate and the availability of a 0% interest rate loan to have the work performed. I qualified for a $2,000 rebate and a $5,000 loan. I elected to have all proposed services performed.
The loan process was automated, efficient and the scheduling process was efficient.
Mike and Devin arrived on time, were professional and considerate of my home as the spent 3 days insulating my garage ceiling, attic and crawl space. Baffles were installed in the rafters to ensure proper ventilation of the attic, whilst all areas contacting the inside of my home ("the envelope") were sealed and insulated to code(and then some), including foam and blown in insulation. In the garage ceiling (below the living room), the 10" space only had 6" of insulation. Holes were drilled in the drywall and insul ation was blown in. The holes were then patched and spackled (not sanded). All seams between the cinder block walls and drywall were sealed with foam and the exposed pipes were wrapped. 
A manager came out the following week to inspect the work performed. He noted several punchlist items and deferred the blower door test until these items were completed. This was scheduled promptly and completed achieving the targeted airflow reduction in the proposal. This report is being sent to the state to verify the rebate and my home may be selected for a state audit. 
Overall I am very pleased with the work performed. My home holds the heat much more effectively. I highly recommend the Mark Group.

"I called Evergreen Electric and setup an appointment for the next day to perform what I figured would be a couple small jobs and to receive an estimate to run cable into new rooms. The original appointment was delayed because of a power outage on another job, but speaking to Josh on the phone, he was willing to come by as soon as he was finished even though it would have been well into the evening. I told him the following day would work fine and we rescheduled the appointment.
Josh arrived the next day and examined our situation. Our house is nearly 40 years old and it turns out the problems were much deeper than I thought. Josh crawled into the attic and rewired the junction boxes that were not just loose but had previously been wired incorrectly. He also spent well over an hour attempting to diagnose why our breaker was tripping without much of a load on it. He was very thorough in his troubleshooting. He replaced the breaker with a higher amp version and the problem is fixed, but he also indicated there is likely more faulty wiring running through the attic buried under the insulation and someone should come back to assess the entire electrical system.
Josh was very courteous and professional and answered all of my questions. After spending about 2.5 hours with us, I was expecting a large bill. I was very pleased when he told me he would only be billing me for one hour.
About 30 minutes after he left, we noticed that a light in the hallway would not turn off. I called to report it and Evergreen responded immediately. Josh came back right away and fixed the problem. He even replaced the light switch free of charge. It is nice to see a company that stands by its work and acts so quickly when something is wrong.
I would highly recommend Evergreen Electric. They are prompt, thorough, and stand by their work.

"Overall it went well except I didn't get the other estimates I requested for insulation and gutters. This was not the low bid but they have done several cedar roofs in the area and have a good reputation. The end result looks really good.

Insulation questions, answered by experts

Canned spray foam has an R-value of R-3.7 per inch. However, it’s not great for use as insulation. Also known as single-component spray foam, it doesn’t expand as much as two-part types that work for insulating the whole house. Save the canned foam for gaps around doors and windows.

If you feel your energy bills are too high or your HVAC system is working harder than necessary to maintain the correct temperature in your home, you may have an under-insulated home. If you’re unsure, consider having your system’s efficiency assessed by a local independent energy auditor.

Yes, PEX pipes should be insulated in certain situations. While insulation is not always necessary for pipes running through insulated interior or external walls, it is recommended for any pipes located in uninsulated rooms, unheated areas, or outside, especially in regions with cold winters. The primary reason is to prevent freezing. Although PEX is more resistant to cracking from freezing than other materials, repeated freezing and thawing can weaken the pipes over time, increasing the risk of a burst.

Asbestos has many beneficial properties, including fire resistance, strength, and chemical resistance. It is also an excellent insulator, which is why it was used in pipe insulation and other building materials for decades. For all its benefits, asbestos is dangerous for human health, which is why it was eventually banned from use in certain products.

One of the clearest signs that your insulation isn’t working as well as it should be is a noticeable difference in temperature throughout your home. One room might feel icy while another is hot as Arizona—this indicates that some parts of your home are either retaining or losing heat more than others. Additionally, a sudden increase in your energy bills, evidence of pests or rodents, or evident water damage are other signals that warrant a thorough inspection of your insulation and potential replacement.
