We recently hired Gavin and his crew for a basement construction project, and we couldn’t be more pleased with the results! From start to finish, Gavin’s communication was outstanding—he kept us informed every step of the way, answering all our questions and addressing any concerns promptly. His crew was equally impressive: polite, punctual, and professional. They always showed up on time and left the work site spotless at the end of each day, which was a huge plus for us. The quality of their work is top-notch, and we would highly recommend Gavin and his team to anyone looking for a reliable, efficient, and skilled contractor. Five stars all the way!
You will not find anybody better. Gavin is truly remarkable. There is nothing that could happen that Gavin and his partners in building and remodeling will not resolve. They are amazing. They go beyond what anyone else would do to satisfy your needs. So if you want a builder that you can trust, Murphy Building and Remodeling is the one for you. We are not the only ones that feel this way. Read his reviews. We hope to use him again if he is willing?
Gavin is not only a professional craftsman but also a great communicator which is extremely important when working with other contractors. I am the operations manager for CT Basement Systems and Murphy's Building and Remodeling worked seamlessly with our team when we discovered major floor joist damage that required someone who really knew what they were doing on a recent project at Amston lake. I would HIGHLY recommend this team and plan on using them moving forward as our go to solution provider!! Thank you Gavin and team! Bill Anderson
We have had Gavin work on two bathrooms in our house and most recently, he replaced our windows and siding. His work is excellent and he is very trustworthy. He is upfront with costs and is always there when he says he will be. I would recommend him highly and would not hesitate to have him back for future projects.
Gavin and his team have been a pleasure to work with. They did a wonderful job with transforming the exterior of our old house. Gavin was patient and professional, working within the timeline we needed for our project. Due to factors on our end, we ended up having to push it and slow it down and he was completely understanding and willing to work with us. He communicated well with us whenever there was a day they showed up early, or were coming at an obscure time. He let us know what was happening, when, and even helped us understand better how the project worked. Overall a wonderful experience. I would absolutely use him again on a future project!
