"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 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

Roughing in and connecting utilities are the hardest parts of finishing a basement, and they’re the parts we typically don’t recommend doing as a DIY project. Unfortunately, your finishing timeline can be extended by weeks while you wait for contractors and inspectors to install electrical wiring, plumbing lines, and heating/cooling equipment and carry out inspections.

You technically can paint wires in a basement ceiling, but there are several important safety and code considerations. It's safe to paint non-metallic sheathed cable as long as the labeling remains visible. You can also paint low-voltage wires and conduit and junction boxes to help them blend into your basement. 

However, you should not paint damaged or deteriorated wiring is a fire hazard because it poses a fire hazard. The same goes for painting over high-heat wires that connect to heat-generating appliances or systems. Be sure to avoid painting multiple coats onto any wires, as that traps heat and poses fire risks.

Yes, most general contractors require an initial down payment. A reasonable deposit is typically between 10% and 25% of the total project cost, although this can vary by project size and location. This upfront payment helps the contractor cover initial costs like materials, permits, licensing, and hiring subcontractors. The remaining balance is usually billed according to a schedule outlined in your contract, often tied to project milestones or completion dates. Be cautious of contractors who ask for a large deposit of 50% or more, as this could be a red flag for a scam.

Whether it’s more affordable to gut a house than build a new one depends on the markets where you'd be buying and selling. However, it’s usually less expensive to renovate a home than to build new construction. 

Most homeowners pay between $100,000 and $200,000 for demolition and remodeling costs, whereas the average cost to build a new home is between $139,000 and $531,300.

If you have the woodworking experience to build a bar from scratch and you have the time, DIYing the work is a no-brainer and can save a few thousand dollars. However, if you’re looking to include a sink, additional lighting fixtures, or high-end bar tops and cabinets, it’s usually a better idea to call in a pro. It will cost more, but the finished product will likely be worth it.
