"Terrible just terrible don’t ever use this company, I hired Innovative to help level my concrete they did a horrible job. Now my driveway has more and even bigger cracks, also I was over charged by the representative who gave me the quote, I specifically asked him that I did not want any cracks filled that I would do it that myself but he ended up charging me for a portion without my knowledge, I found out after it was filled with caulk. I tried calling them about it a few times since I have a 5 year warranty but know one has bothered to pickup my call or respond back. They will easily over charge you to get an extra few 1000 from your pockets. DON’T EVER USE THIS COMPANY they don’t care about you nor bother to even know your name, not once did the representative bother to ask or know my name even though I took the time to know his I was known as “Hey” the entire interaction. Stay away from this company use any other."

Insulation questions, answered by experts

Fiberglass is considered a favorite garage insulation choice due to its combination of affordability, ease of installation, and overall effectiveness. Fiberglass provides good thermal resistance, helping regulate garage temperatures and minimize heat transfer. Additionally, fiberglass is moisture-resistant, reducing the risk of mold or mildew formation.

Unless your cellulose insulation is wet, moldy, or showing signs of mildew or pests, there’s no need to remove it before adding new insulation on top of it. Inspect your insulation thoroughly before adding the new insulation, and if you’re unsure how to assess the presence of mold or mildew, talk to a mold remediation specialist near you.

In some areas, insulation companies require a special license, while some states only require them to hold general contractor licenses. Some municipalities may not mandate any license, although you should always ensure a contractor is fully insured. You can use Angi’s license lookup tool to confirm whether or not an insulation contractor you’re considering holds the necessary license for your area. You can also contact the company for information regarding licenses, certifications, and insurance.

Your home's location, budget, and the type of insulation you’re using are just a few of the factors that can help you choose the right insulation. For example, blown-in insulation is typically used in attic spaces, while batts and rolls are ideal for floors and walls. Blown-in insulation is usually a good option if you're adding more insulation to an area that already has some, but not enough.

Installing insulation helps reduce energy usage, improve home comfort, and lower utility bills by maintaining stable indoor temperatures year-round.
