    Illini Home Improvements - Attic Insulation

    Illini Home Improvements

    (4 reviews)

    I asked Illini Home Improvements to insulate a room that is above our garage. This room was very…read morecold in the winter, and very hot in the summer. They came out and inspected what insulation I already had, and explained clearly why that insulation wasn't working. Basically, the builder had not insulated properly, either due to not knowing the proper way to insulate this type of room, or due to cutting corners. They explained to me what they would recommend, and why, and gave a firm estimate and time frame for when they could do the job. I agreed and their team showed up when they said they would, did the job, and cleaned up after themselves. They stuck to their quote even though the job took a significant amount more of insulation than expected. I was able to inspect their work via the attic, and they did exactly what they told me they would do. So far this room is warmer in the winter, but will never be as warm as the rest of the house due to being over a cold garage, and due to having inadequate heating vents. But at least the room is usable now and we can use a space heater as needed. My thanks to the team, and I'll call them again when I need something insulated. Note that despite the name of this company, they don't do EVERY kind of home improvement; this company specializes in weather-proofing/ insulation.

    Had a multiple door install job for them, since the job was "too small", they recommended one of…read moretheir contractors. I was unhappy with the way the installer (his name was Chuck) handled the job. The screens were torn (not his fault), but instead of replacing them and coming back to finish the job as he said he would, he returned the broken screens to my porch about a month later with a note taped to it with a disconnected phone number. He didn't leave the packaging materials or instructions, so returning them to the company wasn't an option for me. I had to pay $90 for replacement parts, and Illini Home Improvement refused to accept responsibility for the job since the contractor was no longer employed with them. Frustrating to say the least and my doors are still not in working order.
