AWC Energy
AWC Energy
AWC is a leading energy services company that provides a full compliment of services. We offer consulting services, general contracting, full scale integration, installation, sustainability services, and cost-effective energy solutions for commercial, industrial, residential, retail and non-profit customers.
"Lomont and his team were great to work with, simply professional, knowledgeable and so accommodating. I hired him based upon an energy audit we had done by another company. He basically "cleaned up their mess" since they did not do a thorough report in order for us to get our energy rebate etc. He went above and beyond the scope of what we hired him to do, always with a friendly greeting and smile. He reached out to the appropriate agency to push to get the credits we were due and did work that should have been done by the energy audit company. I highly recommend Lomont."

They did a great job and the new windows are perfect."

Nealon Insulation
Nealon Insulation
Your green home insulation company. We specialize in eco-friendly insulation to make your home more comfortable and energy efficient.
"Out 1957 home had minimal insulation in the attic. Over the years some had been added but there were many gaps which made for uneven temperatures throughout the house. Dave and his crew removed the old inefficient patchwork of insulation. They then added channels around the rafters to promote air-flow. Finally they added blown in insulation to achieve R49 or better. The insulation is already making a difference in even temperatures all through the house. Dave and his team were punctual, professional and unobtrusive. The office was very communicative keeping us aware of all phases of the work. We highly recommend Dave and his company."

Better Built Basements LLC
Better Built Basements LLC
Additional e-mail - [email protected]. Award winning. The Mission of Better Built Basements, LLC is to have Connecticut homeowners select us as their remodeling contractor by providing innovative and affordable basement solutions. We strive to build trust and confidence with our customers with precise quotes, honest and consistent communication, professional appearance and demeanor, and accurate time lines for every project.
"Unfortunately I give BBB a 1 star rating. The project began October of 2021 with demolition, upon completion of each phase I sent an email to Better Built Basement management thanking them for their work effort and identifying items that either required further explanation and/or resolution. As the project went on, I became increasingly frustrated with their lack of communication, lack of accountability, lack of caring, and lack of skill. The straw that broke my back was when Jim (an owner) called me a f’ing c’sucker. Randy, (an owner) sent me the following email: No one has time to read your 3-page condensing e-mails. You have done nothing but complaint. It's obnoxious and draining to everyone you come in contact with. There isn't one person who cant wait to have you out of our lives. I terminated Better Built Basements on June 7th, 2022, here are some of the details of my experience: - The demo crew was excellent in and out in a day and did a great job cleaning up - The electricians were very consultative in their approach to the project, providing input on lighting and outlet placements. - Framing was mediocre. Despite using laser equipment, one wall was wavy and the ceiling grid has a large gap. Pictures attached. - New steel stud framing and pre-hung doors should be dead on straight as an arrow instead, two of the doors has an aesthetically noticeable skew. - The replacement to an existing door resulted in using the wrong hinge set for the existing mortices, inclusive of color – all the other hardware is brass they used chrome. Picture attached. - 3 of the four doors were either chipped or cracked. BBB was notified before the ‘final’ paint job, but they failed to address the issue. - I returned home the day they applied joint compound to find glops of joint compound on the floor, which I tracked around my house, and glops on wood work on a floor where no work was occurring. Pictures attached - Following the flooring installation, they left garbage in my basement for 2.5 weeks, then did not take it when they came back – in frustration I disposed of it myself. - Many of joints on the ¼ round trim molding were caulked excessively to cover up sloppy miters. - Cracked switchhplate was not replaced. Picture attached. - Sub-contractors have sub-contractors, who seem to be able to sub contract – direct employees of BBB other than the demo and electrical were rare. BBB demands using a lock box, Many people have the combination, providing little sense of security over access to the home. Overall, BBB does a bad job communicating, managing expectations and fails to deliver on their stated objectives at best they are contractors not craftsman."
