"Following discovery and repair of a roof leak, I needed to have my existing attic insulation removed, and new insulation installed. I received several quotes, and decided to choose Prudent based on David's timely and professional communications, honest appraisal of what the job would entail, and competitive pricing. David and his team did an excellent job throughout the process. They arrived on time, used drop cloths and plastic covers to keep everything clean, walked me through the process and progress, and shared pictures of areas I couldn't easily see or get to myself. At the end of the job, they thoroughly cleaned up all debris and left the house and property as they had found it. We discovered a minor issue later that evening, and David sent a member of the team out to fix it the next day. Excellent communication and work - very happy with the end result, and would hire again in a heartbeat."

"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."

"From initial contact with their sales department we've had a great experience, Corey did an excellent job of taking pictures and showing the problems in our attic. Their level of communication from emails to phone calls was precisely correct by contacting me when needed and not too much with pictures detailing each solution and its associated cost. On the first work day their crew called ahead of time, arrived promptly and came prepared with masks, plastic sheeting, full body outfits and cloth covering for the stairs. In just over 6 hours they had cleaned up the entire attic removing bad sub-floor and other insulation, laid out the foundation for building a large deck space and placed part of the first layer of materials down. They also sealed the attic door along with some of the air vents and ceiling fans. They completed insulating my front porch overhang and cleaned up all of their mess very well. Painters tape was used on corners where they we’re most likely to bump into it for protection and plastic sheeting was setup precisely where needed to keep dust off of our hallway things next to the attic entrance. Overall it was a great first day and they even spotted an issue from a previous vendor who failed to properly connect some of their duct work together (which was the original cause of my daughter’s room temperature being so hard to control the temperature and not easy to spot). The only complaint I have is that while I fully expected the need to finish our attic sub-floor, remaining layers of TruSoftTM Cellulose on the main floor and encapsulate the duct lines with Polyurethane Spray Foam all before finishing with blown-in insulation, they left a key piece incomplete. When leaving they left the duct work leading from our main trunk line to my daughter’s room off. This left a hole in the main trunk line reducing heat in all upstairs rooms but most important is that nothing was connected to my daughter’s room. So around 6:00am she woke up coughing as we noticed the upstairs was around 56 degrees. Overall a simple heads up would have solved everything as we have space heaters, however I did not look into the attic when they left so that’s my fault for not knowing a key piece of the duct line was missing. Based on the overall work complete I would still very much recommend them as Robert (onsite team lead) was very good at communicating and the crew we’re all quite friendly. Their work will last for the lifetime of my house and has already added value to the sale price. In the end they made a really nice attic deck leaving me with plenty of useable storage space. While this is not the cheapest company, the quality and knowledge that I never need to worry about my attic again is certainly worth it."

"The job went as quoted was , everything was great as I expected . The team was very hard-working and professional. They cleaned up and I could not tell they had been here. They were able to get everything done in a day. Other quotes I'd received said it would take 2 days. I am so happy to finally have the old blown insulation out of my house"

"The work was approached in a thoughtful way and executed carefully.  The repair anticipated trouble that had not yet developed into a problem.  The solution is attractive, simple and durable.  The cost of the job was very fair and reasonable.
In addition, +Energy had done work for us previously.  That was phase I of an energy efficiency "retrofit" of our dwelling, an inexpensive construction dating to the post WWII years which is pathetically inefficient from an energy perspective.  The house sits over a crawl space and phase I involved a significant upgrade to the vapor barrier over the soil "floor" of the space, closed-cell foam insulation of the foundation wall perimeter and installation of air circulation and venting so as to maintain a consistent level of humidity in the space and avoid mold and mildew formation that could produce odors that could affect air quality in the living space.  The pricing was very competitive with respect to other estimates and extras were thrown in for the originally-agreed price -- Wow! - we certainly didn't insist on that.  This work was done during the summer, but +Energy has been out a couple of times since to verify that the system is working properly, including this last visit to work on the dormer.  As a result of this visit, they are helping us trouble-shoot a plumbing problem that is unrelated to the crawl space ventilation problem.
In summary, they are enthusiastic, idealistic (they really believe in "green" and in doing a project right), competent and a pleasure to deal with.

"First, there are a lot of dubious roofers out there. We wanted a GAF Roof System with a 50 Year Warranty. American Home Contractors was the only one that was Master Elite Certified by GAF to install a 50 Year Warranty roof in our area. A lot of roofers said that they were, only to find out by the regional GAF Representative, that they were intentionally/unintentionally misleading. It is conceivable that quite a few people out there think they have a warranty, that won't and will find out from GAF that the number one reason they don't is because their installer wasn't certified to do so. Stop right here. American Home Contractors is the one of the very few Master Elite Installer in area. Shaun coordinated our installation. He is the very best at what he does, which is answer your questions honestly and make every request that we made to the owner. From the very first meeting to the signing of the contract to the day of and after the installation, he patiently and promptly answered all of our questions and addressed all of our concerns. Most that we got estimates from focused exclusively on the shingles, but if you want your shingles to last more than a few years, you need adequate ventilation in your attic. Their was a small miscommunication about the day of the installation, but they more than made up for it. We have a very steep roof (11/12 pitch). The day of the installation, the Carlos and his crew put down tarps and thoroughly cleaned after each day. Because the roof was large and pitched, it took two full days and a few hours on the third. The second day was Thanksgiving. That is right, they came out on Thanksgiving to finish but were a few shingles shy of completion. These were Slateline GAF shingles. They are not on the shelves at your big boxes and have to be ordered. But Shaun and his supplier were able to find a pack locally and delivered on Saturday before a big storm was moving in. They crew showed up, finished installation, and we were sealed tight well before the rain started. Everyone was polite and professional. The financing could not be easier. I would not hesitate to do it again. Thankfully, because of the warranty, I won't have to. We have other exterior projects, and these guys have more than earned my loyalty. I will give them first option on those projects. They also have 0% financing for 18 months. This was the longest of all roofers we received estimates from. American Home Contractors is top notch, you absolutely will not be disappointed. A new roof is a major expense and a potentially stressful renovation, but these guys made it a minor hassle. I am sure that all of their staff are great, but ask for Shaun. Probably don't need to ask for him, he likely will be your guy and you are going to be very happy at how easy he and AHC make this for you. Best Regards!"

"There was a problem initially with the radiant barrier installation - the first crew of two were installing 30" wide rolls lengthwise along the roof end to end  instead of from ridge to eave as the manufacturer recommends and made a couple of other minor mistakes which were easily corrected. After talking to the manufacturer, the sales rep offered to take out what had been installed and re-install according to spec or continue as already done with sealing of all seams and a discount on the job. Done this way, the foil would not have the insulation properties per spec but would provide the radiant barrier I desired. I chose the letter option and the barrier work was continued by another crew on the 2nd day. On the 3rd day the crew finished up with the barrier then blew in the installation.

With the exception of the initial problem, the work was done neatly and professionally by courteous workmen who cleaned up completely after the job was done.

"It went great... but this company is no longer in business in the US. So we could not have them do the home energy upgrades. If they were still around we likely would have went with them!
