The project was delivered on time and exactly as we had discussed with them. Where we were most impressed though was in the level of customer service they provided. After removing the insulation in our basement, we found a few surprises that were covered up by the old insulation. Founders was extremely accommodating as we worked with other contractors to get those issues (unexpected and unrelated to insulation) squared away. I realize having the other contractors come in was probably pretty disruptive to their workflow, and Brian and his team said he understood our situation and did everything he could to help us out. I will certainly reach out to them again with our next insulation project.
