"Ron is very responsive to texts, emails and calls. He did a great job describing how he would take care of our siding and trim needs. Everything looks great! He was also able to recommend someone to handle our gutter needs(they did a terrific job). We will hire him back in the future without hesitation."

Meeting somebody, being invited into their house, and listening to their ideas of how they would like to transform their space to better suit their needs excites me. It brings me immense pleasure to be welcomed on an idea based visual journey in creating a customized dwelling in order to improve the quality of function in somebody's daily home life. Bringing ideas to fruition is my specialty. With equal enjoyment in making those popcorn ceilings that you've adored for so long disappear in an array of smoothness, gutting the kitchen where nothing seems to fit anywhere, including the cook, and installing cabinets and lights that transform the "heart of the home" into a space you don't want to step out of, or erecting that garage and mudroom to get your cars out of the weather and the clutter out of your foyer. At Magic Frog Carpentry & Woodworks I live in a solutions based mentality.

"Excellent work and priced very reasonably. Would hire them again."

"Aubrey and Son came out to do multiple jobs to my home starting with new flooring in two bedrooms. I needed a whole new bedroom built in my garage for my mom and he completed that job quickly and thoroughly. She stays warm in the winter and cool in the summers and is very comfortable and happy with her room, it came out lovely. Beau also built a custom shed and picnic table which also he did in a needed time frame and they both came out beautiful. Easy communication and solid work. I would definitely recommend this company to family and friends and strangers alike. "

"To start off I?ve never hired a contractor to complete any tasks on my home so I was worried that things wouldn?t go well as I?ve heard nightmare after nightmare scenarios about contractors. When I first met John I knew things would get done right. He was straight forward and honest about everything. What resources he could work with and how things would honestly go. We came up with a design the was realistic together, (pencil to paper always works best). We measured everything together, he came up with a quote and my wife and I signed. I had interviewed seven contractors prior to John and he was the only one who gave me the right answers and straight talk. We had a clear cut plan and it was executed wonderfully. No problems just weather causing delays and I plan on asking for John?s services in the future. I have already recommended John to several of my colleagues and associates. Also if he ever gets a chance to read this, thank you and Cesar?s family for all the hard work you did. "
