Our master craftsmen are highly skilled in kitchen and bathroom remodeling, carpet and flooring, roofing, room additions, siding removal and installation, decking, and more!

"Ovation Restoration did an excellent job with our home improvement project. In our master bedroom, to take advantage of a fantastic view, they removed a large window from one wall, sealing it up like new, and installed a similar window on another wall. The work was performed quickly and skillfully, with great results. They also turned the double door leading into that room into a single door, creating more space in the room. Concurrently, in the guest bathroom, the old tub was removed, and a beautiful walk-in tiled shower was installed, along with a window with a fantastic view. The project manager Rick was a pleasure to work with, and his team were all professional, conscientious, and friendly. Everything turned out just as we imagined. We would highly recommend Ovation Restoration."

We have been in the construction industry for over 10 years. From building ADUs, high-end kitchen remodels, bathroom remodels and home extensions, we have done just about everything under general construction. Our company prioritizes safety, quality and transparency.

"Me and my wife decided recently to get our kitchen remolded. After some time searching for the right guys to do the job we settled on RG Construction. Richard, who is the owner, is a great guy and super informative. He never left any question unanswered or left us uncertain about anything. His crew works quick, and they pay attention to the tiniest detail. They absolutely are worth every dollar and I would recommend RG Construction to any homeowner, and I for sure will be giving them a call back for any work I need done in the future. Me and my wife are absolutely in love with our remodel."

"Jose, Jesus, and the whole crew are awesome. They put in the foundation, framed, and sided a new addition and did a great job. I have worked with a lot of contractors and Alvarado and Son are amazing. Their price was reasonable, the speed of getting the project done was lightning fast, and the whole crew are really nice people that you just like to have around. I have never had a foundation come out as dimensionally correct as they built it and their framing was outstanding. I literally had the city inspectors giving them compliments ... which just doesn't happen normally. If you have a similar project, look no further! "

Basement Remodel questions, answered by experts

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.

You should plan on waiting at least a year and ideally two to three years after construction before finishing your basement. This will give the foundation time to settle in response to the weight of your home and the expansion of the surrounding soil. You can then repair your foundation and seal any cracks as needed before finishing it to reduce your risk of future leaks or other issues.

Joists and beams are both part of the flooring system above your basement, with the beams spanning the length of your home and getting support from vertical posts underneath, and joists usually spanning half the width of your home with no support posts underneath. The floor joists provide even support to the subflooring and flooring above, and they distribute that load to the beams. The beams then distribute that load down through the support posts to the foundation.

Yes, you can add a door to your basement—it might even be required, depending on building codes in your area and whether or not you’re using the basement as a bedroom. A basement contractor can give you some advice on installation and help you add a door to your basement.

Basements with persistent moisture problems or flooding shouldn’t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage.
