"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."

"Bear Remodeling did an amazing job on my bathroom remodel. The team was nice, courteous and worked hard to get what I wanted. They paid attention to every detail and made sure the design matched my idea. They also did some interior painting and made the whole room look cohesive and stylish. I was so impressed I asked about adding a room to my house and they gave me some great ideas. If you need a contractor for any remodeling project, call Bear Remodeling!"

"We were looking to remodel our kitchen or bath for a few years. We kept getting estimates from different companies and always felt the price was off or the person was not a good fit. Then, finally, we met Shai with Cal Green Remodeling. What a great guy! He is very upfront and honest about what we can expect in terms of cost and work flow. Because of his honest approach, we hired him. We felt he gave us the good and bad and how to resolve the bad as well. In the end, the process was fairly smooth, and the few hick-ups we had, for example, the city and their permit process, were well explained to us at the beginning, so we were ready. Our kitchen or bath looks amazing, and I plan to work with Cal Green Remodeling again. Thanks Shai!"

"Our roof was in bad shape and we needed to have it replaced. I had gotten estimates and decided to go with Home Pro Remodeling. Emil and Brian were our contact people for the project. Emil was very professional and paid attention to our concerns. He worked with us through the entire project to our complete satisfaction. Brian is extremely courteous and helpful as well! The project went very smoothly, was completed before the initial project end date, and the results were beyond our expectations. The job turned our beautifully! Our new roof looks FANTASTIC! Our neighbors have commented to us how great it looks. We are very pleased with our experience with Home Pro Remodeling and would definitely recommend them."

Basement Remodel questions, answered by experts

Yes, you can add a bathroom to an unfinished basement, but you’ll want to take proper precautions if doing so. As with any bathroom addition, you’ll need to make sure that it’s approved by local building authorities first. With unfinished basements, you especially need to keep an eye on proper ventilation practices.

Yes. Renovating your basement has a return on investment (ROI) of 75%, meaning your remodel investment will significantly increase the value of your home. Besides the ROI, your family can enjoy a larger, more usable space while you live there. 

Physically, the most challenging part of finishing a basement is installing egress windows or doors when the space is below ground level. Mentally, the hardest part may be envisioning the project and planning around load-bearing and mechanical obstacles.

The most challenging part of finishing a basement is addressing moisture control. Basement waterproofing is an essential task that requires a professional’s skills and knowledge. If you don’t properly waterproof your finished basement, it’ll be vulnerable to dampness, water damage, and mold growth. Ensuring proper insulation and ventilation to combat these issues while meeting building codes adds complexity to your remodeling project.

Anything having to do with the structure of your home, such as raising the ceiling, is usually the most expensive part of finishing a basement. Another project component that could be a surprisingly high expense is adding an exterior entrance. 

The cost of a walkout basement can be anywhere from $5,000 to $35,000.
