"They are supposed to come tomorrow, they agreed on that. They called and told me that the job is too small and they refused to do the job. Meanwhile I described the job to the woman, the dimensions and the specifics and she agreed but still cancelled it."

"I recently had the pleasure of working with Daryl from American Construction on several home improvement projects and I couldn't be more pleased with the outcome. After the disappointment of another company's subpar flooring installation, Daryl stepped in and completely transformed the situation. Not only did he meticulously level and reinstall the flooring, but the craftsmanship was exceptional. The transformation didn't stop there; he expertly opened up a wall in our kitchen, added stairs, and installed new banisters that have truly elevated our home's aesthetic. The landing steps were another concern of mine, as I was anxious about the wood matching our existing vinyl. To my delight, Daryl matched it perfectly, exceeding all my expectations. Throughout the process, he was not only nice and friendly but also full of great ideas, demonstrating a perfectionist's attention to detail. American Construction is the epitome of professionalism and skill. I highly recommend them to anyone looking to enhance their home. Five stars!"

"Olvin contacted me very soon after I posted my request on Angi. He asked for pictures and quoted me a price. This was a Sunday and by Thursday he was working on the project. He arrived at the specified time and started the work. He covered the floor leading to the powder room with a tarp and started pulling up the old floor. He asked us about how we would like the new tile laid and began to lay the pattern we requested. He keep the work area very clean and was very personable as well as professional.

FAQs for attic insulation installation projects in Valley Stream, NY

The best attic insulation depends on where you live, the project stage, and your budget. New builds often benefit from structural insulated panels for top-tier efficiency, while homes in very warm regions can see big cooling savings with reflective insulation. Blown-in, loose-fill, and spray foam all excel at filling odd spaces in finished attics. Talk with a certified local pro to match the material to your climate, space, and wallet.

You’ll only need a licensed electrician if the project calls for moving existing wiring or adding new fixtures. For straightforward insulation jobs, your insulation installer can work around current cables. That said, never start insulating until a pro has checked any questionable wiring. If you suspect damaged or outdated circuits, book an electrician first to keep the project—and your home—safe and code-compliant.

Without air sealing, even the best insulation can underperform. Gaps let heated or cooled air leak out, forcing your HVAC system to work harder and driving up energy bills. Sealing those cracks before adding insulation locks in conditioned air, keeps moisture at bay, and helps the new material hit its full R-value. Ask your insulation pro to tackle sealing first so you enjoy consistent comfort and lower monthly costs.

Among readily available options, structural insulated panels and rigid foam boards top the charts with R-values that can reach 8.0. They’re ideal for new construction or very cold climates where maximum thermal resistance matters most. If you live in a milder zone, blown-in or loose-fill insulation may deliver plenty of performance at a lower price. Weigh the upfront cost against energy savings—and lean on a local pro’s guidance—to pick the smartest fit.
