"The workman did a wonderful job. When confronted with an issue that they were not expecting, they quickly adapted the plan and installed the awning in a different way, that is even better. I would totally hire these gentlemen again. Really professional!"

"Came exactly on time, did a quick diagnosis, and had the necessary parts to repair my problem. Workmanship was clean and neat, and he vacuumed up the entire fireplace, and even gave me a short "refresher course", in the start-use-stop of the gas unit. Dan was a pleasure to work with and I would reach out to him again if needed."

"Work went very well. Marty with Countryside is a consummate craftsmen. His attention to detail is excellent. Good experience."

"Was awesome! Great excellent service. Had questions before install and walked me through step by step. Wonderful job! Would recommend to anyone looking for camera installation!"

"Everything was amazing. Chuck came in and did a wonderful job on Drywall left everything clean and ready for us to move forward with painting. I would hire them again in a minute, especially if I could work with Chuck."

"Great work! We were very satisfied by the job David did. We had a crack on the ceiling of our son's bedroom where the original drywall tape had pulled up and needed to be retextured. It looks great! Couldn't be happier. He was efficient and professional. We are excited to have him back to do more work for us."

"Let me start by saying that this was not an easy experience. Our furnace is not easily accessible in the crawlspace. However, Ernie and his son handled it well. I originally hired Ernie because we wanted a furnace tune-up. Just a simple replace the filter and do a quick cleanup procedure. Well...as it turned out, we ended having to replace almost the entire system as Ernie quickly discovered that the previous install was done in a very shoddy, cheap and even dangerous manner. Ernie worked with us through the purchase and finance process and afterwards, he and his son worked late into the nights to get our furnace up and running. It took a few tries and even some additional visits back, but Ernie was true to his word and the job was done right. Would highly recommend this business. Hard to find people with integrity, knowledge and also hard work ethic. 10/10 would recommend."

"Work was well done. Total final price was less than estimate. I have used before and was pleased with the quality of work then and this time."

"Service from Jacob was wonderful. He responded promptly and was very courteous and knowledgeable. He had my door knob installed and working again in no time! I would definitely use his handyman services again."
