"I had the service this morning and the Technician was in the building for 10 minutes. The bill was $342.25. Last year's test through a different company was $97.00, they weren't available this year. I called to schedule the appointment and wass told there would be a $70 dispatch charge and the couldn't give me a price on the testing, even though I supplied them the needed info. I call ed to see if the could do anything on the price and I was told the price was discussed in advance, even though they said they couldn't give me a price. I know I won't be calling them for any other needs we may encounter. Would not recomend at all. Would give 0 stars but able."

"There was water in the basement. The plumbers came and said there was something clogging the drain and that the terra cotta sewer pipes had collapsed. They gave me an estimate to fix it. I was upset that it was so high and they asked for a down payment. I asked why it cost so much and they said they didn't know the extent of the problem yet. They did come on Nov. 11th to fix it, but they left half of the concrete they dug up there. They didn't have room in their truck because they had to go buy a hot water heater for someone else and while they were in Butler, they wanted to get it since they live in Karns City. About 2 or 3 days later they came and picked up the concrete, but they left dust all over the floor. They did not bring a shop vac, and they used my broom to clean up the dust. There are still pieces of concrete on the floor, the floor is dusty, and there is a sewer gas smell. I didn't notice it right away because I had a sinus infection which impaired my sense of smell. One of them came out to fix it, but the smell came back. They have never come back after repeated calls. I only got a receipt for the down payment of $1368.75. I never got a receipt for the work done on Nov. 11th and no contract at all which they initially discussed. I don't know if they charged me the balance of $2833.31 or only $1500 which was what came out of my bank account. My card wasn't working right, so I may have paid the balance from another card. I want an accounting of the payment from Nov. 11th."

Pittsburgh Remodeling Company is built on the principles of customer service and craftsmanship. Through partnership with homeowners, the team at PRC can help achieve any vision for your home remodeling project. While every home and every project is different, when Pittsburgh Remodeling Company is involved there are certain constants: The work looks amazing and the customers are satisfied. So if you’re looking for more than a contractor, for a company that will care about your project and final product as much as you do, let’s start a conversation .

"It is on the verge of 2026 and I am still finding examples of the terrible work we received from PRC back in 2019! I have constant reminders of the regret that I have from hiring this company. The latest is an exposed outlet that we were never told about and that I recently discovered because I had to remove a cabinet drawer. Please see the the attached photo and I recommend reading my entire review. Proceed with caution, if you decide to use PRC. I will never understand why they could not provide us the same level of quality that others mentioned in their reviews. Poor work is one thing, but this is a safety issue, and I am grateful that we have not had a fire. I will be consulting with an attorney to determine if any action is possible. I wasn't planning on writing a review about our experience with PRC, but after finding more examples of poor workmanship on a project that was supposed be completed 10 months ago, I've changed my mind.
