"The company did an assessment that we did not need as much insulation as we thought. The gave us a better approach which was cheaper and more efficient."

"Accurate insulation came promptly at the specified time. They were thorough and so professional. The quality of work is fantastic. Couldn’t be more satisfied. This is the second time that we’ve used them and will not hesitate to use them again shall the need arises."

"Debbie showed up on time and seemed knowledgable about insulation. However she had a hard time answering my questions because she was overly fixated on price. That's not necessarily a bad thing but it got in the way of me really understanding the answers. When the quote came in it was very resonable but when i emailed with a follow-up question concerning warranties, the lack of record on Angies List (despite being in biz for 100+ yrs) and a sub-contractor she was going to use for an exhaust ventilation, she wouldn't put some of the answers in writing until after I committed to using her company. After reviewing all of the quotes we received we finally decided to take a leap of faith because she seemed knowledgable and the quote was fair. i emailed saying we wanted to move forward and asked if i could i now get the informatoin i requested in writing. Unfortunately it's now been 5 days so we are moving in another direction. I bet the company does quality work but it won't be with us.

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."

"Person who visited was very polite and noted that what I purchased was likely not something that would meet my expectations. I wanted an energy audit, how my systems could be improved in home, lighting, heating, insulation and air conditioners. What I got was a list of things they could work on and the price to do that work. The work list in no way was considered an energy audit, rather it was a punch list of things I could do based on their visual inspection. I did not have a comparison of work and benefit/savings calculation. There was no checklist of inefficiencies and how that translated into energy losses. For example, multiple hi hat lights in house, they spoke about boxing and insulating a few, less than 10, when I have almost 90 in house. Overall I was disappointed, the tech who came said the offering needed to be better presented prior to start of work."

"I wanted to use a locally owned electrical company, if possible, and was very happy to see the number of very good reviews for Evergreen Electric on Angie's list. I called early in the morning and Evergreen Electric was able to work me into their schedule on the same day which I was very grateful for due to the safety concerns of not having properly working smoke alarms in my house. Thad Sale and his assistant showed up at the appointed time and changed out the six smoke alarms very quickly. They also changed out one I had forgotten about (basement) while they were at my house. Also, Thad Sale gave me an estimate for a potential new electric project which seemed very reasonable. Evergreen was very professional and answered all my questions. The work was done very quickly and I feel much safer having properly working smoke alarms in my house. I would definitely call Evergreen Electric for my next electrical project.

"We had a horrendous situation with a basement floor installation that went wrong leaving our house full of fumes, and a week later we discovered our basement was contaminated by asbestos in the process. When we called Bill and Contractors Unlimited, they were extremely responsive. Although other companies gave us bids, Bill was able to work his schedule to fit us in weeks sooner than the others. Although the cost was a bit more, that saved us money because we were displaced and could not even go into our house because of the fumes. CU set up negative air machines to replace the air, they followed asbestos abatement laws, they cleaned every item that could be salvaged in our house. They even saved more than we thought which really reduced our overall expense. Bill and his team were extremely professional, friendly, helpful, and really went out of their way to ease our stress from this situation. At the end of their process, Bill arranged for a air quality inspection which we happily passed - able to return home. I would gladly recommend Contractors Unlimited for asbestos abatement. I just wish we had called them before the floor guys created such a disaster. Thank you Bill!
