Get matched with top insulation pros in Marshalltown, IA

"The owner was the first to respond to my inquiry. I only wanted to insulate my attached three-car garage that was not insulated, but I knew that even though the house was two years old, all of the insulation was done poorly. Jason offered to either do just the garage space, or take on all spaces for what I considered a very reasonable price. The insulation was blown in and is now very uniform. Rulers placed in the attic showing 19 or 20 inches throughout. The soffit issues were remedied. Carpentry work was done around the attic access hatch to allow for this depth of fill and some siding that was not secured properly and venting that was done poorly was remedied. These additional tasks were done for no additional charge. The crew was anxious for me to check-out their work, so that means they care about what they do. You are always kind of anxious when picking a contractor to do work that you may not be entirely familiar with. I felt very good at the end of this project and would use Affordable Foam again."

"David was extremely knowledgeable about his insulation project! He insulated the two outer walls of our garage, and the three car ceiling! The job was done quickly, cleaned up completely, in a morning! I would recommend this company to everyone! They did fabulous work!"

"Prevailing came in to insulate my basement and attic. The workers were professional and worked the entire time they were here (which seems like a low standard, but I've had situations where 4 people come to work and 2 stand around talking for most of it from other companies). More importantly, they explained what they were doing as they did it, and cleaned up after themselves before they left! Scheduling the service was quick and easy since they were able to use our Alliant Energy quote to avoid a second home assessment, and they came in under budget. Very satisfied - plan to have them back to blow insulation in the exterior walls before winter."

"Jeff Smith is based at the Waterloo office. He was very good at customer service & responded to my emails in a reasonable time given this is probably a busy time of the year (November) for them. I am having additional blow in insulation behind a knee wall & in the attic to bring me up to code. The work has not been completed yet. I am waiting for an energy audit. That is why I can only rate the company as a 3."
