"Originally, I had a great review because the finished work looked great and when I was able to, I didn't see any shortcuts as the team that was hired by the contractor (Mohamed) was there during the week while I was at work. It was good...contracts signed and lifetime warranty was signed of the life of the work. Who wouldn't be happy. Just 2-3 months after the project was completed, problems started to occur. The shower items had minor low flow because of the water that was coming in from the street. They came. Then the handle that held up the shower hand device malfunctioned, the toilet installed was having sealing issues, and the sliding door for the shower was jamming. It took some time for them to look into the issue but when they came, they patched the shower device or seal (later to find out, it was just in drywall with a wood screw on no wood), told me they won't fix the toilet, and shifted and patched the sliding door. I had to get these fixed on my own then the ceiling light they installed doesn't work. I will have to get this fix on my own. I am very disappointed as they gave me all smiles until the last payment then after it was like them visiting to fix the issues was a problem. Again, the problems start in under 3 months. Let me not start on the kitchen. All I have to say is if your were going to take shortcuts and use crappy material, why waste each others time. I have photos of all the problems as well as the contractor."

"I am thrilled to share my overwhelmingly positive experience with this exceptional contractor. Their team recently completed work in my home, transforming the kitchen and installing a bathroom along with an expert job in painting. The quality of their work is simply outstanding, with meticulous attention paid to every detail. The workers were a pleasure to interact with - neat, polite, and extremely professional. They always took the time to answer my questions and explain the process, which made me feel involved and at ease throughout the project. Their respect for my home and dedication to keeping the work area clean and organized was truly appreciated. As for Robert, the owner, working with him was a breeze. His commitment to customer satisfaction was apparent from our first conversation. He ensured everything was running smoothly, maintaining open communication and offering helpful advice when needed. Our first interaction with Kaitlin, the assistant, was just as impressive. She consistently answered calls promptly and courteously. Her responsiveness and professional demeanor made every interaction a pleasure. I wholeheartedly recommend this contractor to anyone in need of home improvement services. Their commitment to quality work and outstanding customer service is truly unmatched. You can expect your project to be handled with the utmost competence and care."

Basement Remodel questions, answered by experts

Costs are guided by renovation scope, materials chosen, project duration, structural needs, and labor. Prioritizing tasks prevents unforeseen expenses.

Adding an extension or addition to your home costs more than a loft conversion in all but the rarest cases where the home's structural integrity is lacking. Because a home addition requires a new foundation section or significant structural upgrades to handle a cantilevered portion, the cost compared to almost any loft conversion is significantly greater for the same square footage.

The cost of finishing a basement is about $18,400 on average. As you can see, the framing portion of this project costs less, because you’re essentially just dealing with laying the foundation for a finished basement. The finishing portion of the project involves a lot more intricate work and design, as well as high-end materials.

Living in a finished basement is acceptable, but only if the space has the proper points of egress and includes smoke and carbon monoxide (CO) detectors to ensure the safety of the occupants. A good way to ensure your finished basement is suitable for use as living space is to get the basement finishing project properly permitted.

Yes, you’ll use a macerator pump to install a basement bathroom without breaking concrete. The purpose of breaking into concrete is to connect the drain pipes to the main sewer line. But a macerator pump will bypass this step and break up solids until they are soft enough to pass through a discharge pipe. That pipe will carry the waste to the sewage line.
