I was surprised the company won't provide to me information about the insulation they installed…read more They won't provide that or an invoice because they were a sub. I need this info for an Energy Tax Credit. Apparently this has to come through the contractor and mine refuses to cooperate.

I had a problem with my back bedrooms getting cold in the winter time and contacted them for help…read more From the beginning they were very polite and helpful and went out of there way to make sure I was satisfied. They were prompt and charged well below other companies. During my initial consult they provided me with a estimate and pictures of my attic. When they came to do the insulation they were on time, cleaned up their mess and did a great job. I would defiantly recommend contractor service of Iowa to handle all of your insulation problems!

Placed two calls to the office asking for a call to have some work done. It's been three weeks…read moresince the first call, and still no contact from Energy Nerds. On second call I was told that they would return call within 24 hours. It's been 72 hours and still no call. It seems as if they use a virtual receptionist or an answering service.

First off, they were nice to our cats. It really puts us off when contractors are rude to animals…read moreso we LOVED Loxley and how kind he was. They were able to get us insulated in a required period of time and even took extra time months later to help with our rebate. They are very kind, considerate, scientifically based, and show genuine concern for their clients. Thank you for being the best.

To any persons considering building a home or doing a remodel, the best investment you can make is…read moreto have Mark and his crew FOAM IT! I am in the process of building a house and you would be a fool not to make the very tiny incremental investment to go with foam. Your foamed house will be safer, healthier, and a helluva lot warmer/cooler by going with foam as opposed to nasty fiberglass. Do your research, fiberglass is like asbestos. It's a glass fiber that if it gets in your lungs NEVER goes away. It embeds in the tissue and doesn't disappear. In addition, the all star crew of Joe, Lucas, and Dakota are neat, precise, courteous, and enthusiastic about what they do. THE BEST MONEY you can spend on your house. It is absolutely baffling to me how anybody building a new house would not use the foam. If you care about the environment, it is VOC free and green guard certified. I cannot recommend these guys highly enough, they really love what they do. The best investment you can make in your house. Joe S.

Our Dec '14 and Jan '15 bills were terrible and that prompted an energy audit by our power company…read more Upon assessment, there was a definite need for ceiling insulation. I contacted Kinzler to come out and evaluate the upper space. During that time, they also agreed to coordinate with an existing garage renovation that I was working on to give them better attic access. On the day of install, they came and installed baffling down to the soffit and filled the space with insulation. We've already had 2 months of bills since the install and are seeing a considerable savings. I was impressed by their cooperation, the professional installation, and cleanup. Most of all, I appreciate my bills being noticeably lower. I whole-heartedly recommend their service to those who are under-insulated.
