"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, the AC&R salesperson, was very knowledgeable and confident. They were the 2nd quote I got for work and came in even lower than I expected (which gave me pause as a low bid is a red flag). But true to her word, they did the work professionally (mostly...see below) and promptly. While I had another company do the energy audit for the Pepco rebate, AC&R took over the work, did the blown fiberglass one day and the spray foam the next.
For the blown fiberglass in the attics above our additions, they added spray foam (from a can) around any gaps per the contract and foam board baffles at the soffits. The installer noted that all our soffits were blocked and the batting insulation was too wide for the rafter channels, so he leveled it out as best he could to ensure an even coating of blown insulation. At the end, he sealed up the gaps between the attic and our to-be-finished upstairs (cape cod style, so all one room).
For the spray foam insulation, the team came in the next day, and I had to be out of the house due to fumes. I did come back around noon as they expected to be done well before then. They didn't know I came in and I went to the back of the house to watch TV on my work break. The one annoyance was during their cleanup, one of the installers came down into our kitchen and then saw me. He said he was looking for a vacuum cleaner to clean the stairs. I told him don't worry about the carpet as it was getting pulled up, but this was the one piece of unprofessionalism I noted above. Contractors should NEVER use the homeowner's property; they should bring their own tools, including vacuums!
While the spray foam can get very messy, they kept the splatter mostly contained to inside the crawlspace, not the finished flooring. However, I was surprised that they didn't tape off the outlet covers or light switched. since the particles are so small, we're going to have to replace the switches/receptacles at our cost. Also, there was a storm door screen that wasn't covered and now needs cleaned. Basically, I think they should have taken more care in covering the very few items we left upstairs and the outlets/switches.
They didn't spray around the window frames (large gaps where window weights used to be) because the open cell foam would expand too much. If I wasn't there, I think they would have just left, but it was clear in our contract discussions they needed to insulate those spaces too. They used a few cans of "Good Stuff" equivalent, but didn't fill in the gaps entirely. It did the job well enough, but it's a ding against them as I expected more preparation.
Lastly, I thought that AC&R would walk me through all the scheduling and final "test out" (for the Pepco rebate), but I had to contact them and schedule with someone different each time. They were always prompt, but I expect the experts to know to do this for/with me rather than expect me to know the process. I go through it once in a lifetime while they do it weekly.
While the end of the review sounds more negative than positive, I would definitely recommend AC&R out to others as they're priced right, they have been in business for over a century, and like any contractor, you just need to follow up to be sure everything is done to your satisfaction.

"
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.

"Unfortunately we found asbestos containing floor tiles under a laminent floor in our house. We made the decision to have the material abated and conduct a kitchen remodel (new cabinents) at the same time. There are not many options in the area when it comes to asbestos abatement contractors and even fewer who will provide both abatement and renovation services. We quickly decided to go with Contractors Unlimited because they offered both services and Bill was responsive, knowledgable and very personable - and we were not disapointed. Bill and his crew performed an excellent job, ontime, close to the originial estimate price (we expanded the scope slightly), and at a more than reasonable cost. Bill and his crew kept us in the loop as the demolition/abatement progressed, calling us throughout the day. After the work was competed he kept in touch as we worked to schedule our replacement kitchen and worked with us to accomodate our tight deadlines. As the new cabinets were installed, Bill and Dwayne oversaw the installation, insured that the floors weren't damaged and paid attention to the little details with respect to craftsmanship.
We would highly recommend Contractors Unlimited and will definitely consider them in the future for any renovation needs!
