"My sewage ejector pump in basement would not stop running and I was looking to replace it. I texted Dean two pictures of the pump, he was able to give me a quote over text and the price was quite reasonable. He received a new pump on 5/22/2023 and came over to my house. After opening up the old pump and checking, he told me that the only thing that is really broken is the check valve, the switch got stuck but is still functioning, and the pump itself works fine. I ended up asking him to only replace the check valve and the switch and this saved me about $1000 from the original plan. I appreciate Dean's honesty, professionalism, and a job well done."

"In response to my project dtd 10/31/2025 posted on Angie, I was contacted by Steve with phone number +1 (347) 425-5862. I was given a contract with Yellowstone Constructions and Waterproofing which was signed. The contractor showed up with Jay Cunningham on 11/17 who was paid $1550 as advance. The crew of 2 men removed the bluestone and found underlying structure that was uneven. Jay then told me that the stones cannot be put back and asked for $12k to fix the walkway. When I told them I don t have that kind of budget, he told me that the advance is non-refundable and they cannot do anything until I come up with more money. They left the site. Over the next couple of weeks of back and forth, I told them I cannot arrange for those funds. As a way to close out the contract, I asked to demolish the remaining walkway and remove the debris. The last phone call took place on 11/25. Since then I have not received any response from them. On contacting Angie.com today, I was told that they do not have any records for Yellowstone contractors but they could map the phone number to Marinko Radakovic who was also matched with my original requirements. The other phone number provided for Jay Cunningham 203-528-2009. Both these phone numbers have gone without response. I am out of the advance paid and a half demolished walkway. This looks like a bait and switch done by this contractor and attempt to fraud."
