Overall Karl and his team did a great job replacing attic insulation in my 80 year old home. Karl is a seasoned pro and very thorough. Gave us good options for our job and was upfront about certain aspects of the job that were not essential and would just inflate the price. His price point a fraction higher but worth it for piece of mind. Flexible in scheduling. Showed on time and completed a tough, dirty job in under 3 hours. Amazing.

Karl supervised and made sure the work is done properly. Karl provided a detailed estimate and executed a quality job. He worked on my attic and crawl space. I highly recommend him.

Karl, the owner, personally came to estimate the job and also when the job was actually being done. He provided very upfront, detailed estimate, explained every option and steps to be taken and did exactly what he promised (actually better, as he found ways to avoid some cuts in the ceiling - saving me money). The whole job was done very professionally, clean and right on time. Would definitely recommend.

Capital was fast in responding, took great care in performing quality work and made sure they addressed any requirements of concerns. The owner worked on my project with his crew and ensured things were done right. I was very impressed and highly recommend them to anyone seeking to install insulation.

Review by in Alexandria, VA
I had such a good first impression of the company from the very first phone call with their scheduler. The owner Karl came and gave us our estimate and then was here when the work was being completed, from start to finish. They came on a very rainy day and cleaned up behind themselves...all of the employees on site that day were very friendly. Karl answered our questions timely and was a real pleasure to work with. I would recommend Capital Insulation to anyone needing to replace or upgrade their current insulation.

Seal of Approval

What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.
  3. Verification of State Business Filings
    For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
  4. Criminal Records Search
    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
  7. Legal Search for Civil Judgments
    We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them.
  8. Liens Search
    We use 3rd party data sources to check the principal/owner of the business for liens placed against them.
  9. Identity Verification (SSN)
    HomeAdvisor verifies the social security number(s) of the owner/principal for identity check purposes. This check applies primarily to smaller business entities.
  10. Identity Verification (Reverse Phone Lookup)
    We conduct a reverse business phone lookup to identify records matching the phone number information provided by the business.

NOTE: Member service professional information confirmed as described above may change or expire over time; while HomeAdvisor attempts to maintain accurate and up-to-date information, and confirms changes when notified, we cannot guarantee that profile and screening information is accurate.
