Bad experience. I hired them the first part of August. I was told my 34x24 pole barn would be done that October. All they had to do was set the posts, frame two overhead door openings and put up the metal siding. I asked the owner the 3rd week of October. He said the following week. I had a generator sitting on site the entire month of October. It was a waste. I had concrete flooring scheduled in November.

I had to reschedule. The end of November they finally delivered 4 posts. Ever since, I've been told tomorrow. Unfortunately, tomorrow never comes. I've have been told several completion dates. They even put up damaged sheets of metal, knowing that they would have to replace them. The quality is way below par, but at this time I just want it finished It's now the end of August(a year later) and the building still isn't done.

I've had to reschedule my overhead door installers numerous times. Now, I have to hire a contractor that can finish the building. My insulator and garage door installers won't put me on their schedule anymore, until they visually see that the building is ready.

We had KB build us a 34x36 shop with living space above. They did a great job on the building. They were easy to work with and got the project done in a prompt manner and on time. They are also very fair with their pricing. We would definitely have them build for us again. Thanks KB builders!

KB Building Supply ordered supplies for us over a year ago and will not pay there bill, we have been very accommodating in working out a payment plan they agree to but never follow through, payments have not been received (the checks in the mail). They deserve a 0 rating if anyone does business with this company has to be a fool. its unfortunate you have to give them any type of rating to post this they deserve a 0

Worst quality of work I have ever seen. They built a pole barn and is still not completed a year later. Installed all water lines for the barn at 2 feet instead of 6 feet all the hydrants they installed were not even half deep enough. All tin on roof is dented not one square cut on the entire building. Wouldn't have these guys build a birdhouse for a 3 week bird. I feel like one star is too much for them. Owner won't own up to a thing. Don't waste your time calling these guys!

I have been on a project where I had to attempt to fix things they claimed they did and did not do. For example, strip the top soil from the building site in which that could not be fixed. Install the poles for the structure poured in a footing which we went in and poured exterior footings which is also how I discovered that they did not strip the top soil from the building footprint. 0 stars

We keep coming back, but set aside a LOT of time between when you put down the deposit and the project is finally finished. Months. We have routinely found that they will take 6+ months between first order and finished product. Having said that, we have 3 three-sided livestock sheds that KB build in 1990 and 2000, 15 years old, and they are all in terrific shape. Cattle, horses, pigs- all are used 8-12 months a year by some class of livestock, and all the sheds are in the same condition in which they arrived.

These sheds are built to last, even in our horrific winter winds (just make sure they're staked down on the day they arrive- they roll and fly if the wind catches them wrong without staking). We like KB, and have ordered 6 sheds, 1 large hay shed, and 1 barn from them. Happy with everything but delivery promptness.

These guys are the best in the business! We had our tiny home moved by them and they really went above and beyond in every way. When a problem arose, their expertise and creativity in finding a solution really proved to be invaluable. This move was not an easy task as it was a large building, out of town, up a hill, in the mud. Sam and Kevin were not only professional, but knowledgeable and patient. I would highly recommend this company for anyone looking for a well-built shed, or to assist in your move. The turnaround time was within a few days.
