Testimonials
We have remodeled and built on many occasions and have never had such a positive experience. Tom and his whole team made the experience fun and exciting. We built our home 25 years ago and it needed a major remodel and refresh. We also had some things that we wanted to add or change based on our changing lifestyle. Not only was the project on budget and largely on time, the communication and interaction with Tom, Jason, Brian and many subcontractors was so professional. As with any construction project, things came up that needed creative solutions and when we wanted some changes or additional scope, the answer was always “we can make that work”. The budget was managed carefully and we never felt “change order fatigue”. We so appreciated the professionalism and would welcome the opportunity to work with Gallagher again. Thanks to the whole team for making our home one that we can love for another 25 years.
Brad & Stephanie Creswell
Tom and Leanne Gallagher were wonderful to work with. Tom is the consummate professional-quality without compromise, easy to work with, approachable, and tremendous management of the job. He tended to the smallest details as the project progressed to bring our home in on time and move-in ready without a punch list. Leanne, as a designer, has a fabulous eye and chose finishes, designed cabinets, and set the tone for the look of our home that gets compliments from every guest. This is the third home we have built and in our experience, Gallagher Co. builds the most beautiful, highest quality product out there. We love our home and can’t imagine a better building experience and a more lovely end product.
Nan Burton
You have created the most beautiful yet livable home we’ve ever owned. Lots of thought went into the features: outdoor living area with overhead heaters, fireplace, and complete bathroom for lakeside living. The interior spaces are perfect for a family and also for entertaining. The cabinetry, lighting and finish details are timeless and elegant, but not too formal. The dock material is awesome, very low-maintenance and discourages ducks from lounging on the dock.
Elizabeth Huber
You have creat Jennifer and I couldn’t be more please with the gorgeous home you built for us. It is absolutely everything we ever dreamed and more. From the moment we saw the black and white house from the outside we were captivated, and the attention to detail on the interior is unlike anything we have seen. Your sense of style plus quality construction results in a home that we home to live in for the rest of our lives. Thank you for your help in resolving some of the very minor issues that any new house would have. We appreciate your honesty, professionalism, and the quality of your work. It has been an absolute please becoming your neighbor and friend. I would be happy to discuss your work and our home with anyone.

I just wanted to say a big thank you for helping my dream of a new bathroom/laundry/mud room come to life! Our new master bathroom is an oasis of luxury – I feel like I am stepping into a four star hotel when I come through the door. The laundry and mudroom function so much better for our family now too.

We hired Tom for a renovation project to our home in the summer of 2010. The project included building out new windows and replacing old ones, demolishing and rebuilding a deck system, tearing down existing stucco and replacing it with wood siding, and all of the finishes required once the work was completed (such as interior drywall repair, wood flooring repair and interior/exterior painting & trim).
Because the job required that the new renovations blend and interface functionally and aesthetically with the part of the house that was not renovated, we needed a contractor with superior expertise and attention to detail. Tom’s broad experience, creativity and integrity made him a perfect fit for our needs and he didn’t disappoint us. His solutions were creative and cost effective and were delivered on schedule with the highest quality. We highly recommend Tom for any renovation project of any size and complexity.
Mark & Elaine Bolger
Everything is great. Thank you very much for taking care of it. You go out of your way to make sure everything is right… and that is very rare these days. I’ve had several compliments. I love it and only wish I’d done it years ago. All of the men you selected to work here were delightful. First of all, they were prompt! And pleasant, courteous, neat. Thank you for taking the customer’s concern seriously. We would be honored to have you see the finished project. Bring your folks too!
