Hi Anil, Thank you for sharing your feedback. We're sorry to hear that the experience didn't meet your expectations. Our pricing was provided before the work began, and we're glad we were able to step in quickly and help complete the installation. Since the bidet was supplied by the customer, its design and positioning options were determined by the product itself. Those requirements must be adhered to or you'd have even bigger problems. Our goal is always to leave you in a better position than we came -- and complete the job to ensure you won't have issues when we leave.
We take pride in the quality of our work and always strive to provide professional, reliable service. We appreciate the opportunity to help and are sorry the value didn't meet your expectations. If you have any further concerns about the installation, please contact our office. We'd welcome the opportunity to discuss them with you.

Just had my home converted from oil to gas with Jim Dorsey and Son. Excellent service and they did a great job cleaning the area after removing my old system. I had gotten other prices but went with the reviews. I made a great choice. This is the only plumber I will be using in the future.
Update**" 10/5/2026
Still have the same heating system they installed! Still works fantastic!! Had an addition put on and needed to split a zone. Jim Dorsey and sons came out, split the zone. Cost less than the quote from Gem and was done in a day! Best install and service ❤️
Price assessment: Great price
