Ask for the written scope, current license and insurance details, and recent project references before booking, especially for a major system replacement.
GS Pro Plumbing installed a new Lochinvar combi boiler for us, and we couldn’t be happier with the entire experience from start to finish. Outside of our failing tankless hot water heater, our previous system also had been installed so poorly that it needed to be completely repiped. George worked tirelessly day in and day out to build a brand-new system that not only performs flawlessly but also looks incredibly clean and professional. His attention to detail and craftsmanship were outstanding. When the job was finished, you would have never known he had been there, aside from the immaculate new boiler system he left behind. We highly recommend George to anyone looking for quality work and true professionalism.
