    If I could give Shane a 10 I would. It was a big job. Well pump, water softnet/filtration and plumbing kitchen sink excellent quality work. Took one day and left the areas spotless. Will definitely call for Shane for future projects

    Had service performed on our HVAC system by Amir. He did a fantastic job, checked and cleaned our inside system, checked all of our vents, and checked and cleaned our outside unit. Amir also made great recommendations for keeping everything in good running condition to ensure the system stays at its proper performance. Highly recommended.

    Donnelly's diagnosed the cause of our septic system failure and had a crew, led by Joe Madden on-site the very next day. The excavation team did a great job, both at initial digging and at final soil replacement and grading. Plumber Joe Madden replaced our broken pipe, paying close attention to details of proper fit and seal that make us very confident of the work performed by him and assistants. They also added a clean out port. The entire crew was very professional, competent and clearly took pride in their work. Excellent job!

    Jeremy did a beautiful job of replacement of our old, leaky basement sink faucets and supply lines. He also replaced our non-functional shut-off valves. Donnelly's has such great service. Jeremy was professional, diligent and careful. We are very pleased with this job.
