We take great pride in our extreme professionalism, timeliness, and superior customer service on every job. We make sure to develop a lasting relationship, so that the next time service is needed there will be no question on who to call. 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

A finished basement must have a heat and electrical supply with an entrance that meets building code requirements, such as a stairwell to the home's main living space. It often must include finished walls, ceilings, and floors. If the finished basement includes a bedroom, it should have a heat source, an egress window, and a closet.

Remodeling, as opposed to finishing, means altering an already finished basement by adding a bathroom, bedroom, or living area.

Renovation enhances functionality, increases home value, and can add new space for personal or family needs. It typically modernizes older unfinished basements for new uses.

Permits may be required for major repairs, structural work, or electrical and plumbing restoration after a flood. Check with your local building department to determine permit requirements and associated fees for your flooded basement cleanup project. Obtaining the correct permits helps ensure work is done safely and up to code.

Lifting a house and adding a basement is one way to add usable square footage. Lifting or jacking a house is a complex process, and it can be expensive, not to mention that you won’t be able to live in your house while it’s lifted, due to safety concerns. Lifting a house should only be done by experienced professionals.

Generally, a wall can bow up to 30% of its thickness, or around 2.5 inches for an 8-inch-thick structure, before it becomes an urgent situation. If your basement wall bows more than 1 inch, it's time to have a basement inspection to determine if a repair is necessary, depending on the soil conditions and structural specifics. Walls nearing 4 inches of bowing will require significant repairs. More than 6 inches of bowing usually means the wall will need replacing.
