"I called at 8:00pm on a Tuesday night. The plumber came before 10:00pm as promised. He replaced a leaking shut-off valve and associated pipe within an hour. Cost was as quoted for one hour labor plus parts which were less expensive than expected. No extra costs for travel time or anything else. We will definitely use again."

"Mr. McDowell is an expert in this area and had the fireplace serviced, up to code & working quickly. I can now have it inspected for the purpose of our homeowners insurance. I had hired him to provide a second opinion about the fireplace repair. He saved me the cost of replacing the fireplace-$3,000.00; and from a predatory salesman who had red flagged the unit."

"It was great finding Washington Home Doctor Inc. Our water heater started to leak. We found them on Angi.com. The next day the company installed a new energy efficient water heater. The gentleman were on time and professional. One week later they were hired again to replace a copper pipe. Will definitely use them again for our plumbing needs."

"The technician arrived promptly at 9 a.m. as scheduled. However, the 50-gallon water heater that I purchased would not fit in the space so the technician had to wait hours for a new one to be brought to my home. He was very courteous and professional. He apologized several times for the delay. A short time after the new water heater arrived, he had everything up and running. This was my first time using Sila, and I would certainly consider contacting the company in the future."
