Kelvin Company

I am really, ridiculously unhappy with Kelvin Company.
First, the good. The work is good. The gentlemen who showed up to dig my pathway and pour the concrete were professional, quick — clean up was great. At the end, it looked like the pathway had just always been there and there was little evidence that they had been there.
My problem with Kelvin is the time schedule that they operate on and the front office interactions.
This job was, and should have been really easy. A monkey could have installed this walkway if they had access to a cement mixer. After reviewing the site, Paul took 1 week to get me a quote. On the quote, he offered me a cheaper rate if I signed a contract and combined with work he was doing in the neighborhood. The problem, however, is that by the time he got me the quote and I had time to get a permit, that job was already gone.
No cheaper rate for me. And I had already signed a contract. When I asked about it, he essentially blamed me for not acting fast enough.
4 weeks after signing a contract, a crew shows up (unannounced) to dig a pathway. And they dug in the wrong spot. We actually wanted to push the walkway closer to the house, but they didn’t know this and dug where they thought it should go. Consequence: I had to cut some major tree roots we were trying to avoid.
During the pre-​pour inspection, Kelvin failed because they put down 1 inch of gravel instead of the standard 4 inches. Looking at my contract, I was paying for 4 inches. When questioned, Kelvin said they didn’t want to have to cut more tree roots and wanted me to call the inspector to appeal.
After I had them give me what I payed for, the walkway passed inspection and the concrete was poured within 1 day. The forms were taken off the next day. And it looks great.
3 weeks later — I“m still waiting for a final inspection, but am getting phone calls to pay my invoice. An invoice I’ve never received.
Kelvin’s front office is ridiculously and utterly, completely ill prepared to deal with people. They have no idea how to speak to their customers nor answer inquiries in a timely manner.
Perhaps this is because I was a small job and not worth their timely care — but every customer is a voice.
I would NEVER hire them and encourage anyone considering their lower prices as an indication of a deal to consider the old adage — you get what you pay for.
