"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."

"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!"

Basement Remodel FAQs, answered by experts

In addition to overseeing new home builds, construction managers work on large renovations and major remodels. For example, they may work with designers and oversee the construction of a finished basement, kitchen renovation, or a home addition. They may also oversee large-scale remodels, such as the update of a historic home. Construction managers step into small projects for more specific assistance, such as building budgets and compiling the team.

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.

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.

Kitchens and bathrooms are typically the most expensive rooms to renovate. The high cost is due to several factors, including expensive appliances like ranges, hoods, and refrigerators, as well as costly fixtures. The 'bones' of the room, such as electrical and plumbing, are also expensive to move or replace. Because of the vast amount of prep work, finishing, and specialized labor involved in a relatively small footprint, these projects can cost double or more than a living space remodel. Even when trying to renovate on a budget, kitchens and bathrooms will likely carry a hefty price tag.

The cost of finishing a basement is about $18,400 on average. As you can see, the framing portion of this project costs less, because you’re essentially just dealing with laying the foundation for a finished basement. The finishing portion of the project involves a lot more intricate work and design, as well as high-end materials.
