Kerry and his assistant did fantastic work on two big projects in our house recently. I can't say enough great things about their professionalism, attention to detail, and craftmanship. Kerry is a talented carpenter, is extremely knowledgeable, and is very experienced. His assistant, Albert, is equally as talented. Albert handled the first job almost entirely himself, which involved tearing out a closet in our downstairs bedroom to turn it into an office. It sounds easy, but believe me, it was a huge job and took several days. After the closet walls were smashed, cut, and torn out, the walls needed to be re-taped, plastered, textured and repainted. When finished, it was absolutely perfect. It is impossible to tell that there was ever a closet there.
Next, we hired Kerry to put together a group of cabinets and drawers we ordered from Lowe's, which was to become our new kitchen island. Again, it sounds simple, but it is anything but that. None of the cabinets and drawers fit exactly together, so Kerry had to precisely cut many finishing pieces of wood and veneers to make it all fit together, as well as anchoring it all to the floor. He also had to run an electrical outlet to the side of it.
He finished it all in one day, including getting all of the handles installed. It was an amazing feat of precision carpentry and it looks impeccable right down to the trim around the bottom of the island. I highly recommend Kerry and Albert to anyone needing any kind of carpentry done in their home.

We hired Kerry to build a closet in a spare room as well as install a barn door between our master bath and bedroom. Both of these jobs were completed on time and with a lot of attention to detail. Kerry had wonderful design ideas for the closet and made sure to check in often to get our feedback. For example, on the barn door he made sure we like the positioning of the door handle before he attached it. We will definitely call him every time we need work done on our home.

We found Kerry on yelp.
Our job seemed simple to us-build a bench for seating and storage. His questions and recommendations revealed his experience and eye for function and decoration.
The completed work is simply beautiful.
Only issue was time line which was pushed back several times.
Husband and I agree the wait was well worth the wait given the price and beauty of the finished product.
We will use Kerry in the future and establish a complete by date that we all agree on before job is commissioned.

Can't say enough great things about Kerry... So happy I found him by chance doing a search on yelp! What started as some basic handyman work has turned into the only guy I call when I need any work done on my home. I know he will be on time and give realistic expectations on job completion and cost estimates. His work is impeccable and he's also very good with cleaning up. Rates are reasonable--especially for the quality of work he has done for me. I highly recommend him...no job ever seems too big or too small. You can tell he takes pride in what he does and he also offers some great suggestions whenever I need it.

Needed a quick electrical repair at my place, found Kerry on yelp, he was able to come out right away and fix the problem. He was fast, knowledgeable, had the parts on the truck, and best of all he has great prices. Didn't take advantage of my emergency situation. I would highly recommend using him for any home repair needed.

I will post some pictures soon to show you some examples of his work. If you are looking for a craftsman, then this is your guy. Kerry does the work himself and he is a perfectionist, even more so than I am for my own house. I have had so many unremarkable jobs completed by carpenters that were ok, but had little annoying errors that smacked me in the eyes every time I looked at the work. This guy is a master carpenter and his work is flawless, greatly exceeding my expectations. I imagine you could probably find someone to do the work cheaper (his prices are more than fair) and you could probably find someone who has no work who could run over to you house immediately and make a big mess... but if you want superior work at at fair price, this is your guy. Be patient, get in line and he will get to you! He is busy for a reason.

After Kerry finished my job, a neighbor who is a contractor asked to come in and see his work... he had been observing him while he worked and wanted to see the finished product... he was blown away with the quality of the work. That in itself is quite an endorsement.

I'll let you know what I think once he follows through with a phone call or an email, both of which he has yet to do. I have had to make the calls and do the asking and so far received no bid and no calls back. Guess he doesn't want the work.

Kerry is great, very creative and is a master craftsman! On time, prices are fair and does awesome work! He can do Kitchen, Bath remodels, Plumbing, Carpentery, Electrical etc... He is a one stop shop all in one. He helped install a Tankless Water Heater to replacing my toilets, He also helped in lighting in our kitchen and put a nice Andersen French door in. He is very meticulous and goes beyond great service. I highly recommend him...
