"Very well. The housemate using it likes it. It works well and is a great improvement over the old, leaking and very noisy one. Will definitely have more work done in the house, as needed."

"Absolutely GREAT! I had places to go in December and ordinary bathing and laundry had become extremely time consuming and the problem was worsening. He came out on an already busy day for him and had the whole system (more complicated than some) removed, and the plumbing working again very well in a bit over an hour. Wonderful! I can't add enough superlatives! Left a clean area, besides!"

"Aldo was great. He came about two hours after I called him. I have an old AC unit that I wanted him to repair so it would last a couple of more months. The last HVAC guy told me there was nothing to be done and handed me an estimate for a new unit: $17,500. Aldo took care of the problem, and for a very reasonable price. I only wish I had called him first. He was very helpful and not rushed. It has been many years since I hired anyone to repair anything that impressed me as much as Aldo did. He's a star."

"I had a problem at my vacation rental. John contacted me quickly when I posted my problem for quotes online. I had a failing septic. It was no longer draining. John came out and accessed the the situation and based on faulty drawings I supplied, he gave me an estimate for repair. I agreed to the figure. When he discovered that the drawings were wrong and he only had to dig up 5 feet (not 14) between the septic tank and the seep box he lowered his estimate. You can't ask for more honesty and fairness. He and his worker completed the job in less than 2 days. Hire him!"
