"We hired Thorsen Construction to do major work on our 19th Century historic townhouse on Capitol Hill and found them to be outstanding partners in a very complicated project...They were very sensitive to working in a house that had lots of antiques that needed to be protected and made sure dust and dirt did not penetrate the rest of the house...The team was always prepared to answer questions and quickly address concerns along the way in a courteous and professional manner...They are a world class construction company in our estimation.
