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."
"My wife and I have worked with TRL Builders on several major projects over the years. They rebuilt our home after the 2017 Tubbs fire. Several years ago they also completed an expansion to our restaurant, Jackson's Bar & Oven. Both the expansion and the rebuilding of our house turned out great! The quality of the workmanship and attention to detail throughout the process were outstanding. Tom Lovold and his team were organized, talented craftsmen and delivered what they promised. Our home turned out beautifully and was even recently featured in Sonoma Magazine. After the fire, many contractors had to do a lot of juggling and prices for materials were going up rapidly. TRL Builders navigated through the process and even saved us some money on materials by pre-ordering them. I can confidently say that I would recommend TRL Builders to friends and family. If you're looking for an honest, dependable contractor who takes pride in their work; I wouldn't hesitate to recommend TRL Builders."
"My company, Sonoma Second Home, has worked with Tom for many years on projects ranging from small upgrades and renovations, to full custom homes and guest house builds. Throughout every project, he has been professional and dependable. His team consistently delivers high quality craftsmanship while working with subcontractors who share the same high standards. Our clients have always been very happy with the quality of the finished product and their overall experience working with him. Tom communicates well, stands behind his work, and is someone we confidently recommend whenever our clients need a contractor they can trust."
"I have worked with Tom Lovold from TRL Builders on multiple projects, both residential and commercial. Tom brings calm to every construction site through his strive for excellence and clear communication. As an interior designer, I especially respect his attention to detail, quality of workmanship, smooth collaboration with the design team and achieving an optimal outcome for our clients."
"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."
