Why clients continue to call TRL Builders
"We've enjoyed the benefits of working with Tom and his team on a number of tenant, capital and repair improvements over the past ten years. His work has been completed successfully and in a professional manner each time. Tom has a wealth of experience and resources and uses those to come up with creative and effective solutions. I highly recommend TRL Builders for consideration in any commercial office building related project."
"Each time, they provided outstanding service throughout our projects. Their workmanship was excellent, they stayed on schedule, and their communication was clear and responsive every step of the way. Being a healthcare facility, we require our contractors to adhere to a high level of safety. They provided us with a written safety plan and followed it to a T. I would highly recommend TRL Builders to anyone looking for a dependable contractor."
"We've worked with TRL Builders on several major projects over the years. They rebuilt our home after the 2017 fires and also completed an expansion at our restaurant, Jackson's. Both projects turned out great. After trusting them with both our home and our business, I can confidently say they're the contractor I recommend to friends and family."
"Through every surprise, Tom was steady, professional, and highly competent. As the scope grew and plans changed, Tom never hesitated — every request was met with a calm, can-do attitude that's rare among builders. His pricing was clear and fair, and his communication outstanding. We recommend him without reservation and are deeply grateful for the home he helped us create."
"Working with Tom Lovold was an outstanding experience from start to finish. He made a complex process feel clear and manageable, brought in the right subcontractors, and truly listened — while also offering smart, cost-effective alternatives that helped us stretch our budget further — delivering exactly what we wanted. We love our home and would highly recommend him."
"We had a great experience working with Tom on our ADU build. He was extremely responsive and consistently followed through, which made the project feel well-run from start to finish. Pricing was transparent throughout, and expectations were clear from the beginning. Tom is reliable, professional, and delivers high-quality results. Highly recommended."
