"John put the new roof on my home. He was professional, efficent, and affordable. He has my repeat business."

- Howard D.

"My wife had been unhappy with the kitchen in our house since the day we bought it but it was just too costly to upgrade. John took the time to come in and explain to us what we could do to improve the look of the space without going overboard on our budget and my wife and I couldn't be happier."

- John S.

"I was nervous about buying an older home but a friend assured me that John could help me with any project, big or small. Now I feel like I live in the custom home I've always wanted."

- Michael L.

"I've heard about all the horror stories of contractors cutting corners and taking forever to get even small jobs done. John exceeded all of my expectations and more and I wouldn't hesitate to do another project with him."

- Misty B.

"When I inherited my parents house, I knew it would take some work to get it market ready. John and his team helped me make the improvements I needed while not going over budget. The house sold in 2 weeks!"

- Katie M.

"John was reliable and honest and he did quality work on my home. I would refer him to anyone."

- Sam R.

"I've been a homeowner for 12 years. Since then I have relied on John and his team on dozens of occasions - from additions, to my dining room makeover, and most recently - our new roof. Thanks again, John! Always affordable & reliable!"

- Sarah H.

"John, thanks again for delivering on your promises. My addition came together faster than I expected and under budget. Good old fashioned customer service. I'd recommended you guys with confidence!"

- Jon B.

"These guys are the real deal. They helped me remodel the upstairs of my house back in 2006, and they came back this year to help me with 2 new windows and new siding. Unlike other contractors we've used in the past, John was a class act from day one. No games, just honest good quality genuine service."

- Joe Z.

"When we originally built our house, I loved the green siding we choose. Needless to say, 35 years later I was not so fond of it. John redid the siding on our house and it came out so wonderful that two of my neighbors went to him for the same thing."

- Mary C.

"I was pretty upset by the damage the storm caused to my house. No one wants to have to deal with that. John made it as painless as I could have expected. Thank you."

- Tim O.

"I have an older house that I've lived in for about 30 years and I knew it was due for some costly updates. The replacement windows that John installed for me really were a great way to update my home and they saved me money on my energy costs at the same time. It really made the investment worth while."

- Mark M.

"My home was a 'fixer-upper' investment that I purchased in 2006. John and his experienced team helped me re-surface the entire exterior of my home. Roof. Siding. Windows. Doors. It looks like a new home and I made a healthy profit during an economic downturn when I sold my home in 2009!"

- Bob P.

"I decided to put an addition on our home becasue our family decided to unexpectedly grow. John really cared about the time constraints we were under and my wife was so excited that the nursury was ready for when we brought the baby home."
