"We hire Geico builders for our kitchen remodeling project, and I'm happy to share my experience: Working with Zaya and Geico Builders was a great decision. They were professional, friendly, and easy to work with. From the start, the process was smooth and efficient. The craftmanship of my remodel kitchen and attention to detail were exceptional, and the end result far exceeded my expectations. From the design phase to completion, their communication was excellent, and I felt completely at ease with them working in my home. The design solutions completely transformed my kitchen, making it both functional and beautiful. I highly recommend Geico Builders for anyone looking for a stress-free and satisfying remodeling experience."

"We found Cal Green Remodeling while searching for companies on google. After meeting a few companies, we decided Shay was the best choice for us. The main reason we went with Shay and Cal Green, was because of his honest appraoch to the the whole process. While it appeared the others were saying what we wanted to hear, Shay told us the facts without attempting to lighten the situstion. For example the timeline with Shay seemed realistc compared to the others and also he provided a very detailed estimate that covered all cost and potential cost involved. Simply stated Shay made us feel comfortable. As we expected, he was the best choice. The process was smooth and Shay kept us in constant communication with updates, and completed the work on schedule. Our kitchen came out amazing and we love it! I would highly recomend Shay and Cal Green Remodeling for your home renovation. Thanks again to Shay and Cal Green Remodeling!"

Basement Remodel FAQs, answered by experts

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.

In many homes, an unfinished basement is an ideal place for an in-ground pool. The concrete floors, protection against water damage, and access to the ground below your home make this a large contender. Speak with a local basement remodeling contractor to ensure your space is right for the large construction.

Any bowing in a basement wall indicates a problem that needs to be addressed by a professional. If your basement wall bows more than 1 inch, it's time for an inspection. Generally, a wall can bow up to 30% of its thickness (around 2.5 inches for an 8-inch-thick wall) before it becomes an urgent situation. Bowing of 2 to 4 inches is more straightforward to fix than bowing of more than 4 inches, which will require significant repairs. If the bowing is more than 6 inches, the wall will likely need to be replaced. The sooner you address the problem, the easier and less expensive the repair will be.

Home improvements that increase value offer a high return on investment (ROI) and can enhance your quality of life. Upgrades to your home’s curb appeal often add the most value, with garage door replacement having one of the best ROIs at 93%. Other high-value exterior projects include replacing your front door, upgrading siding and roofing, installing a stone veneer, adding new windows, and landscaping. For interior renovations, a fresh coat of paint provides an excellent ROI. Major projects like a kitchen remodel or upgrading appliances and HVAC systems also add significant value, as potential buyers appreciate the peace of mind that new equipment provides.

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.
