Needless to say, the last several (hot summer) weeks have been miserable. After having an energy audit completed by HESS, we received a very fair quote for all of the work that needed to be completed. We did have to wait about a month for the next appointment to get the work done, but it was totally worth it. The men who completed the job yesterday were professional and friendly. The house is already so much more comfortable than before. Thank you, HESS!

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!

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.

We had the provide insulation in the attic of our house and were told afterwards that they would follow up with us to make sure the other rooms in the house were taken care of. Once they completed the larger more expensive project in the attic they stopped answering my calls, texts, and emails. They had someone come over to the house to check the other rooms had them pull up our floor boards to take a look then never followed up to actually provide the service. 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.

In 2022, I requested an energy assessment for temperature differences. Luke the technician was…read moreprofessional, and did a thorough job. 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.

The project was delivered on time and exactly as we had discussed with them. Where we were most impressed though was in the level of customer service they provided. After removing the insulation in our basement, we found a few surprises that were covered up by the old insulation. Founders was extremely accommodating as we worked with other contractors to get those issues (unexpected and unrelated to insulation) squared away. I realize having the other contractors come in was probably pretty disruptive to their workflow, and Brian and his team said he understood our situation and did everything he could to help us out. I will certainly reach out to them again with our next insulation project.

Zion Insulators was the most thorough in their estimate, as well as most competitively priced. I wish all our estimates for home improvements had this same combination of quality and affordability. Felix and Jose replaced the fallen baffles, air sealed everything, created a dam for the attic hatch to maximize the insulation around the hatch, brought our blow-in insulation up to R-49, and took pictures of their finished work. The degree difference is now just 3 degrees, and much more comfortable. To top it off, Felix gave me a ring about a month later to see how the insulation was performing, and will stop by to make some very minor improvements around the attic hatch that I would not have demanded or expected. So I give them all the credit for being amazing professionals who go above and beyond. I'd say I did plenty of research, and can recommend Zion Insulators without hesitation. Thanks again!
