"We hire Geico Builders for our kitchen remodeling project, and I'm happy to share my experience: working with Zaya and Geico Builders team was a great decision. They were professional, friendly, and easy to work with. Form 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 top 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 highly recommend Cal Green Remodeling and mainly Shay! We originally hired him for our kitchen and master bathroom project. Shay had awesome ideas and he did a stunning job, much more beyond our expectations! After the kitchen project was completed… we decided to have him continue and to also remodel our two bathrooms, some structural changes to the ceiling and installing new roof, raising the ceiling (in 12”) at the entry, completely modernizing our living room by opening walls, removing old flooring, removing old rock fireplace and replacing with modern, classic tile. Exquisite. We developed a trusting relationship with Shay and his team of workers and craftsmen. They helped us with design ideas and helped us stay within our budgets, and were honest when they felt they could not accommodate. They gained our trust and respect. We recommend them with confidence and look forward to using them in future projects!"

"Every remodeling project comes with surprises, and ours was no exception. Instead of making excuses, Builders Group came up with practical solutions and kept the project moving. They were honest about costs, transparent about timelines, and handled every challenge professionally. That’s the kind of contractor you want on your side."

"We hired McCormick Home Builders to remodel our living room, and we are beyond pleased with the result. The team was professional, worked efficiently, and Aris design ideas made a huge difference. The room feels so much brighter and more spacious. This was the best decision we made for our home, and we were already planning our next remodel with them."

"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."

"My project was a major renovation of a 1985 Victorian home that suffered a devastating fire. Erik and his team did a beautiful job following my architect’s plans, and was also proactive about calling out necessary changes. He was very patient with all of my changes and very specific requests, and was a very calming influence when unexpected surprises inevitably arose during construction. The final results are beautiful, and an historic house has been saved. I look forward to working with Erik again in the future!"

"Leo did a very extensive plumbing repair that required digging through my bathroom floor and replacing a huge pipe to the outside. He also prepared and installed piping and fixtures for a bathroom remodel. Always showed up when he said he would and had a great crew. Cleaned up as well. Would highly recommend."

Basement Remodel questions, answered by experts

Yes, barndominiums can have basements. Barndominiums are typically built over concrete slabs, so barndo basements are not very common. However, it is possible to include a basement in a barndominium blueprint as long as you’re building completely from scratch. Barndos can have the same types of basements as traditional homes, including full or walk-out basements.

Yes, in most cases, finishing a basement is worth the cost. The project adds valuable, usable square footage to your home and typically provides a return on investment (ROI) of 70% to 75%. For example, an average basement refinishing project costing $32,000 could add between $22,400 and $24,000 to your property's value. The final value added depends on factors like your location, the quality of materials and workmanship, and the features you include, such as a living space, bedroom, or bathroom. To be officially counted in your home's total square footage, the finished space must comply with all local building codes, including requirements for points of egress. However, in areas prone to flooding, a finished basement might be seen as a liability by potential buyers and could potentially decrease your home's value.

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.

Finishing a basement can provide a great return on investment, by increasing the market price of your home when you want to sell. Beyond that, there are many reasons to finish your basement. Doing so expands the usable square footage of your home, so you can enjoy it more, even as your family grows. Renovating your basement costs less in terms of time, energy, and money than having to search for and buy a new home.

Yes, most general contractors require an initial down payment, typically between 10% and 25% of the total project cost. This upfront payment helps cover the costs of materials, permits, and subcontractors. The remaining project costs are usually billed after specific project milestones are reached or on set completion dates, as outlined in your contract. Be wary of contractors who require a significant deposit of 50% or more upfront, as this could be a red flag for a scam.
