EXCELLENT Based on 28 reviews Neil Hause2024-09-06Trustindex verifies that the original source of the review is Google. Schwanz did a great job repairing & painting my home. They are extremely organized and their communication was excellent throughout our project. I recently recommended them to a friend who is now also scheduled Schwanz to paint their home!

They provided pictures of their work and were responsive to questions and requests throughout. They were also very affordable. We will use their services in the future, and appreciate the hard work! Vince Pierri2024-04-25Trustindex verifies that the original source of the review is Google. I used Schwanz Construction for a project a few weeks ago. Called to get a quote, they were able to show up two days later. Promised me the quote in three days, but gave it to me the next day. They were able to start the actual work a week later. Work was perfect. Even had a crew come in a few days after to verify my satisfaction. They are reasonably priced, started the work quickly and didn't disrupt my house. Would use them again and recommend them to everyone. cameron getchell2024-02-05Trustindex verifies that the original source of the review is Google. Absolute terrible company with terrible management! Don’t Easter your time money or energy with these people Dawn Hodges2023-10-24Trustindex verifies that the original source of the review is Google. This company came to our home, scraped and painted all of our exterior woodwork. They did a fantastic job. We did a walk around and found a few spots that needed to be touched up. Without hesitation they set some guys by to do the touch ups and it looks fabulous. Great company to work with, and we will use them for future projects. Frank Dunlavey2023-08-30Trustindex verifies that the original source of the review is Google. They were on time and work very hard each day. They were very friendly and wanted to do the best job they could. Clean up each day before leaving for the day. They did a great job and we are very happy! Thanks Frank weldon zhang2023-07-31Trustindex verifies that the original source of the review is Google. They did a good job on repairing and painting the exterior corners of my house. The price was right and the painters are the right people.
