"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

Some older homes have toilets in the basement to combat sewage backups. This type of toilet, also known as a Pittsburgh potty, acted as a safety valve over the incoming sewer line. If a line backed up, it would back up into the toilet because it was the lowest fixture in the home, keeping it out of sight and away from the finished areas of the house.

Basement toilets were also used by workers with messy jobs, like those who worked in coal mines or steel mills. This way, they could clean up and avoid tracking dirt through their home.

Permits may be required for major repairs, structural work, or electrical and plumbing restoration after a flood. Check with your local building department to determine permit requirements and associated fees for your flooded basement cleanup project. Obtaining the correct permits helps ensure work is done safely and up to code.

It’s less expensive to finish your basement than it is to build an addition to your home. The average cost to refinish a basement is $32,000 (between $7 and $23 per square foot) while building an addition to your home costs $50,325 ($80 to $210 per square foot). Depending on the size of your basement and other factors, like moving plumbing and electrical, refinishing a basement is a more cost-effective option in most cases.

Renovation enhances functionality, increases home value, and can add new space for personal or family needs. It typically modernizes older unfinished basements for new uses.

Yes, adding a walkout basement will usually bump up your property value. Most homeowners prefer walk out basements because the exposed wall that’s level with the ground provides more utility via a ground-level exterior entrance, and they can fit full windows, which adds natural light and ventilation to the basement area. The only exception might be in areas prone to tornadoes, as walkout basements aren’t as safe as regular basements during a tornado, particularly if they include large windows or glass sliding doors.
