"You can't go wrong working with Chip. He installed a new water softener and my reverse osmosis water filtration system. Chip brought a wonderful young man named Sean to install the softener while Chip installed the Reverse Osmosis system. What a great team they made. Both men very knowledgeable and personable. They job was done very quickly with both men working. They worked together to figure the best way to install the RO system under my sink with plenty of room left to keep my garbage bin and other supplies in easy reach inside the cabinet. What a great experience!"

"Dave came in and created a new, ADA compliant (for my wife), small bathroom layout that solved a host of issues including a larger shower footprint. After seeing how well the larger shower fit, we decided to continue with all new fixtures, beadboard sheathing, crown molding, new window, and LVP flooring (see attached New Bath pics). No chasing subcontractors, it was all Dave. He also increased the water flow in the kitchen and bathroom by tuning the water pump, implementing a new crawl space plumbing design, and increased the water intake out in the lake. He offered the opportunity of re-locating the hot water heater out of the crawlspace where the old one had rusted and increasing the HW capacity. We couldn’t say yes fast enough. All of this and not one leak! Dave also identified and corrected several issues with our electrical panel when he was installing the water heater and baseboard heat. I don't often write reviews, but we were just so impressed with Dave. We were incredibly happy with his work, but what we were most impressed with was how quickly he responded and followed up with us, how competitively priced he was, and how professional and friendly he was. He listened to what we wanted, he researched requests, made recommendations, and selected quality products for our changes. We made incremental changes after we started that added to the project scope but he always sent us an estimate for those changes via email beforehand so we could formally agree or contact him to discuss any questions or changes that we had. He takes a lot of pride in his work and wants to make sure he provides you with what you want. I wish all contractors did business like this!"

"This was the second time I had Al's Plumbing come out & do the work -- he has proven that he is the "master" in the universe of plumbers. I am so very impressed with his expertise. Wish I could have found him years ago..............He knows his stuff & he is my plumber for life."

"I had an Absolutely Fantastic Experience!! My husband & I were so lucky to have gotten Jason Scharf to come out to our home, he was very insightful, helpful, courteous and very professional. Jason explained step-by-step what he was doing along the way & what would work best within our home with 4 different price ranges that would work for us. Jason was very informative. He mentioned and advised me on some items that would require attention on a monthly basis which I was grateful for. Upon completion, he reviewed the bill and explained any questions that I had. I was very pleased. Overall, Jason’s work was outstanding. I would recommend Jason from Astar to anyone I know that is in need of a central air system in their home. He was one of the kindest, funny and coolest Design Specialists by far. Thanks again Jason you're the Best! We can't wait for everything to be completed."

"If I was able to give more than 5 stars, I would! I cannot thank Al enough for coming out to replace my hot water tank. He is very professional and took the time to explained things to me. The job he took on was not an easy one, Al showed great resourcefulness in finding a solution and I'm very thankful he did not walk away from this challenging job, when I'm certain others would have. Al is the consummate professional as well as being both friendly and courteous. I would highly recommend this company!"
