  • “I can't recommend Trevor and his crew enough! Trevor sold us our home six years ago. He was the absolute best to work with. Always on time and flexible. Over the last six years Trevor has completed multiple projects on our home. Each and every one as completed with great care and very affordable. We have multiple bad experiences with contractors but not with Trevor!”

    Heather Tatum

  • “It was a pleasure having Trevor work on our home. He was honest and upfront about pricing and time frame. I will use his company for all of my contracting needs.”

    Shelley Strayhorn

  • “Trevor and Team has redone our entire home. From bathrooms, to kitchen to outside siding and decks. We can't say enough great things about them."

    Greg & Michelle Stayhorn

  • “Trevor does great work! I call him for most home reno things. He built a roof over my deck, he repaired some siding on the front of my house & he even hung a chandelier for me in a weird/hard to get to spot in my foyer. His pricing is fair, as well!”

    Brittany Himburg

  • “Trevor is awesome to work with. Not only did Trevor find the property but proactively managed the entire sales cycle, including helping me find a new lender, using my preferred closing attorney and helping securing contractors to do any repairs on the property. He was honest throughout the entire process, always keeping my needs first and foremost.”

    Mike Schultz

  • “I worked with Trevor not once, not twice.. but three times. Trevor is thoughtful, accommodating and willing to go the extra mile for his clients. Even my sibling used Trevor to purchase and sell a home. I would highly recommend Trevor as your realtor. It will be an experience you’ll never forget. Not only was Trevor our realtor, he became our personal friend."

    Jackie Oliveria

  • “Trevor and his crew at Johnstone & Co did a fantastic job on our project. They tore out our old two-level deck and built a brand new one with a shed-style roof and a screened-in upper level — it turned out amazing, transforming our open deck into a much more usable space for year round comfort. For me, it was the attention to detail.

    They also installed a new front door with sidelights and finished a basement bedroom for us, all at a very fair price. Everything was done to code, the team was professional, cleaned up and hauled away old material, and followed up to make sure we were happy. Couldn’t ask for better — I highly recommend Johnstone and Co.”

    Patrick P

  • “ Trevor was nothing short of perfect in helping me sell my home! He worked with me and went above and beyond to get my home sold the way I wanted to do it. He is a local with a lay of the land and knows the market very well. He listened to me and helped me get the price I wanted for my home. I highly recommend Trevor for buying, selling, or any real estate need.

    Dylan Scates

  • "Trevor is a true professional. We moved out of state and left our house in his hands. He maintained our house in our absence, taking care of everything that we couldn’t and provided us with updates along the way. We trusted him in selling our house and would not hesitate to do it again given the opportunity. We highly recommend him."

    Reena Feiertag

  • “Trevor built an attached back patio that runs the length of our house a few years ago. He did such an amazing job that we used him again to close off a 2 story foyer to make a play area and also to build a playroom under the staircase.”

    Ben Gibson

  • “We had a leak above our garage for many years and numerous contractors tried to repair it with no luck. Trevor and his team came in and fixed the issue first time. Everyone was courteous and neat. Would highly recommend him again”
