Our home inspection indicated several issues with the attic insulation. We interviewed a few companies and were deeply impressed by Capital Insulation. Karl and Jonathan are true experts. They undertook a thorough review of the entire attic structure, including not just the insulation but also the venting and overall construction, and identified several issues. They carefully documented every aspect of the proposed project and walked us through the recommendations. It was precise and thorough and gave us great confidence in their expertise. As the project got underway, there were several structural challenges - and with each one, they found a way to remediate and fully address it. The end result is excellent. The house has immediately felt warmer and, because they also added insulation to the walls where needed, the overall soundproofing in the house is greatly improved.
We have previously done an insulation project in another home. The difference in approach and execution was night and day. If you just want someone to take out old insulation and pump in some new stuff, go with anyone. If you want experts who understand how homes are constructed and every detail of how insulation should be installed for the strongest results, call Capital Insulation.
On a personal note, Karl and Jonathan and their team are awesome to work with. They are kind, honest, and very approachable. The team arrived on time and worked diligently all day, taking extremely good care with rugs, floors, etc, and leaving everything in great condition. Truly a 10 out of 10 on every measure. If you have an issue relating to insulation, you can absolutely do no better than calling these guys.
