We live in a three story town home…read morewith southwest facing windows and on a 90 degree day like today the A/C has barely had to turn on. We are so much more comfortable and I can already tell we are going to save hundreds on our power bill every year. We are just blown away at the quality of work that was done; it really feels like the biggest life hack. We love that it came with a pearl certification too so we can have documentation in case we ever want to sell. Just an unbelievable value and we can't believe we didn't do it sooner. Thank you so much HESS! Such a great experience! Wanted to see the best way we could improve the comfort level of our three story townhome and now we know how to do that and so much more. Mohammed was so knowledgeable and professional and truly was a pleasure to work with. An home energy audit is a must for every homeowner and Home Energy Saving Solutions truly feels like the gold standard of that.

Recently a company connected with Dominion contacted my husband and me to offer a home energy…read morereview and estimate on weatherizing our house in time to take advantage of the tax credits available until the end of the year. Since we did not know enough to evaluate the proposal he provided after his review, we talked with someone we knew who was volunteering with a climate advocacy group in this area. He suggested we contact Mohammed at Home Energy Solutions for an energy audit. We did so and were able to schedule it very quickly with Mohammed spending a great deal of time doing a thorough inspection of our three attics and our many windows and doors. We were surprised at just how bad the situation was in general air leakage, in the ductwork, and in the insulation over one part of our house where, from the pictures Mohammed took, it looked like a raccoon had gotten into the attic and torn up the insulation. When Mohammed sent us a contract to fully insulate our three attics, removing the insulation in parts, sealing the edges and around lights, and more, and we had a ton of questions, he promptly responded with clarifying information and willingness to adjust the work and add on caulking our windows and weatherstripping a door and more. Also, the price was most reasonable -- significantly less than the other company with more items included. He then scheduled the work at our convenience and his team of three, led by Eric, arrived promptly at 8 AM and worked hard until 5:30 pm. In the 53 years we have been in the house we have done about five major remodeling jobs/additions, and a whole bunch more of minor improvements. We have been very happy with most of the firms and workers, and a couple less so. Of all the crews that have worked in our home, Eric and his team were outstanding in every way -- so helpful, courteous, hardworking, quiet, neat, patient in answering questions, and so much more!!! They cleaned up afterwards and it was great to wake up this morning and feel the notable difference in the especially leaky part of the house. We cannot say enough good things about HESS -- Mohammed, Eric and the other technicians!!! And, we are looking forward to significantly lower energy costs. If you want a great job, at a reasonable price, HESS is the place to go!

After getting several quotes, I chose Founders insulation to remove my old fiberglass insulation…read moreand replace it with cellulose. I would give them five stars for their prompt communication setting up the initial appointment, for providing a competitive quote and then answering all my questions about the insulation product they were going to use. I felt my concerns were heard and responded to respectfully, especially by the owner Brian. The crew that did the removal and installation were also punctual, friendly and took good care of my property. Despite working long hours in 100 plus degree conditions. The only reason I dropped a star was because after the dust settled and we were able to access the attic we noted a few things that bothered us. Most of these issues could have been easily addressed if the installation crew had been more communicative with us throughout the process. Instead we had to deal with these issues afterwards which was rather frustrating and took several weeks to resolve and required us to call in other contractors. I would still recommend this company for all the things that they did well. But more and better communication from the work crew would have made this an overall five star experience.

Needless to say, the last several (hot summer) weeks have been miserable.

The house is already so much more comfortable than before. Thank you, HESS!

I called Pride Insulation to give me an estimate on adding insulation to my home. Hal called and…read moregave me a time and date for the estimate. Warning sign #1 - Hal arrived 20 minutes late but I thought oh well things happen. Warning sign #2 - When I showed him where the attic hatch was he informed me he didn't have a ladder and asked if I had one he could use. Warning sign #3 - Hal then informed me that the light on his phone wasn't working well and asked if I had a flashlight he could borrow. After supplying Hal the items needed he finished and gave me an estimate. Afterwards I had several questions and tried to reach Pride Insulation. I left several voice mail and email messages. No response. Finally, I left a deserved review on Yelp and quickly received a call from Hal (Pride Insulation). Hal said that this review would hurt their business and asked if there was anything he could do to help the situation. I explained that I had called and sent email and had no response. And if this is how they treat a potential customer image what kind of response you would get if there were problems once the job was finished. Hal agreed to work and correct the problems. We agreed for him to do the work on Monday February 27, 2017. I paid him 50% after he argued that he usually gets 100% of the money up front! Hal then said he would call me the next day to set up the insulation install. So I waited all day Tuesday. All day Wednesday. All day Thursday. No call. Tonight, Thursday evening I called Hal and canceled any insulation install and requested a refund of the deposit. Be careful doing business with any insulation company that: (1) Arrives late with no call. (2) Doesn't have a ladder. (3) Needs to borrow a flashlight. (4) Won't return phone calls or email. (5) Asks for 100% deposit. (6) Doesn't do what they say they will do.

I have called both my point of contact and the office multiple times with no response. As a result I am having to go with another company to have the rest of our work done which is extremely unfortunate.

However, the evaluation mainly focused on upstairs ducts, and bathroom vents, but didn't address my primary concerns. When I received the quote, it was extremely high, so I decided to go with a different company--a decision I ultimately regretted. When I tried to return and schedule service with the company, I was told Luke doesnt work there anymore, so I was assigned to Ben. I requested to do another energy audit because the initial evaluation didnt provide CFM readings from Living Room and Dining room which is a colder area of the house. He was going to charge another $595 for another full audit, I asked for a discount and he said no. He said its not needed as he has all the information. When I agreed, he emails me back the following day to cancel because I had previously hired another provider due to Budget reasons. I find it disappointing that service would be refused based on my past decision to explore other options. This approach doesn't reflect the level of customer care I would expect.
