John gave me a free inspection and came up with a solutions tailored to our home. He gave us a very reasonable quote and I’m so glad we went with Capital. They’re a veteran owned business, and they took very good care of us. Spotted a lot of issues in our attic from previous contractors and remediated them. Since the installation and seal, our AC is effortlessly keeping our home cooled through this historically hot summer. We’ve had a lot of contractors over the years and have often been disappointed by the quality of their work. John was extremely professional in diagnosing our issue, coming up with reasonable, affordable options, and executing an immaculate insulation removal and replacement. You will be glad you chose this business.

Karl and crew were excellent. Showed up on time (7am) and finished reinsulating my attic by mid-afternoon. Karl thoroughly explained the procedure for removing old insulation and debris plus installing the new insulation. When crew member John discovered our two upstairs bathrooms venting needed to be fixed, he told me exactly what needed to be done and redid the venting. Afterwards he provided photos of the attic and a short video showing the crew at work. Great job by all.

Karl and his team did a great job. Their communication was great and they set proper expectations (told us to expect 2 days but their team managed to get it all done on one day). His team also was very educational on how to improve my attic airflow and what additional items that I should consider getting someone else to look at.
