"Alpha insulation is a good choice. Their installation was great. The guys cleaned up all their mess. Which is a plus for me. Miguel was easy to talk to. I told him what I wanted done to my house and he gave me a great price for what I asked for. So I hired him. I would recommend alpha insulation to friends and family."

"Fibers Insulation was extremely professional right from the first call. I chose their service from Angie’s Lust and within minutes Geovany responded. He came out on a Saturday to provide a quote and followed up days later. Members of the company were here at the designated time and did a stellar job! I insulated my garage to add better barrier for my garage to enhance a new AC unit to offset summer heat. Geovany followed up after the installation to ensure all went well. To ensure a better look, taping will be added to keep it looking great. I will recommend them to others in my gated community as I am very pleased with the result."

"Good company to work with! They were very nice and seem to be honest over the phone as well. They came on time and did the job. My A/C system didn't work good and a strange smell came out of the ducts when I turned the A/C on. 
Jose that did the work, checked everything and connected a machine to the system letting it run for a while and added a cleaning chemical that made this smell gone.
I will hire them for the future. it was a hassle free with this company.

"Zohar at Best Builders Group came out to our house in order to check and see how and what to change in the existing kitchen. Zohar and his team of people did a wonderful remodeling job from A to Z. We were very impressed and surprised from the high quality of the work and from the professionalism of the workers. During the work, several issues came up during the remodeling project but the team and Zohar handled all of them with no effect to the completion date and with no additional cost. We are looking forward to hire them soon and to remodel all of our bathrooms."

Insulation questions, answered by experts

Because of the moisture concern, open-cell foam requires a vapor barrier. The barrier protects against high humidity and moisture exposure in rooms such as basements, bathrooms, or exterior walls. It wouldn't be necessary in dry interior spaces.

It’s best not to install a radiant barrier directly under insulation because it requires an air gap on at least one side to work properly. Instead, you should install the radiant barrier over your existing insulation to create an air space to reflect the radiant heat.

To cover your HVAC ducts and air vents during construction, use plastic sheets or drop cloths secured with painter's tape. Be sure to cover all supply vents on your floors and walls, as well as the larger HVAC return vent, which is typically on the ceiling. While canvas drop cloths can also be used, they may not catch all the fine dust. It is crucial to shut off your HVAC system or at least the zone where construction is happening. Running the system with vents sealed can put significant strain on the blower motor and air handler. For additional dust containment, you can also hang plastic sheets over doorways to separate the construction area from the rest of your home.

Yes. Proper, complete insulation will ensure that you trap the most cool or warm air inside your home, preventing high energy bills. In addition, insulation tends to settle and compress, leaving gaps over time; the more you insulate completely during the initial installation, the less you’ll need to do down the line.

One of the disadvantages of soffit vents is they can bleed warm air from the attic during winter, resulting in slightly higher energy bills and a colder house. There are ways to mitigate this effect—mostly just closing the vent in the fall. What’s most important is your attic is ventilated to some degree in the winter.
