"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!"

"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."

Basement Remodel questions, answered by experts

If you’re not sure which method of raising the ceiling is best for you, here are a couple of considerations to help you make that decision. A professional ceiling company will be able to help you determine the best option for your home.

  • How long you are planning to live there: although raising the basement ceiling will increase the value of your home, if you’re planning to sell the house, then go for raising the house.

  • The condition of the foundation: to lower the floors, your foundation has to be intact whereas raising the house will allow you to restore the damaged foundation.

The best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.

Costs are guided by renovation scope, materials chosen, project duration, structural needs, and labor. Prioritizing tasks prevents unforeseen expenses.

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.

To determine if your basement walls are suitable for finishing, assess their structural integrity and moisture conditions. Look for any signs of damage, such as cracks, bowing, or excessive moisture. Ensure proper drainage and address any underlying issues before proceeding. 

Consult with a professional if you're uncertain about the structural stability or potential risks associated with finishing your basement walls.
