Robin Renovation believes in more than just construction. Family-owned and operated, we pride ourselves on producing a truly quality product, maintaining open and honest interactions with all customers, and empowering our employees to succeed both on and off the job site. While we specialize in bathroom and kitchen remodels, we offer full-service framing or finish carpentry, including tiling, drywall, window/door projects, cabinets, etc. overseen by formally-trained Journeyman carpenters with decades of on-the-job experience. The mission of Robin Renovation is to hire and train people of all backgrounds and to provide them with wages that will support home ownership and with the skills necessary to turn fixer uppers into dream homes. To us, community comes before profit, and we work hard to cultivate a work culture that encourages each employee to do things the right way and never to cut corners. We promise you will not find another remodeling company that cares about your home as much as we do. We’d be honored to work with you, so please reach out to us.

"We are so happy that we went with Isaiah and his team at Robin Renovation! The projects included new hardwood flooring in two rooms and on stairs, gas fireplace insert replacement, lots of tiling and drywall. All of the employees who came to our home did exceptional work along with being communicative, tidy and patient with our dogs. I received continual updates from scheduling manager Jodi who kept meticulous details about all of the simultaneous projects. The cost of the work was well worth it the quality. I highly recommended Robin Renovation for anyone needing renovations!"

With over 20 years of experience serving Washington and Oregon , Ovation Restoration, LLC is the solution for all your construction needs. 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!

"We recently had our master bathroom renovated by Ovation Restoration, LLC. We discussed what we were looking for and our budget and Rick indicated he could do the job within that budget. We are very happy with the bathroom now. The old bathroom was very builder basic and now it is much more us with our choice of items (flooring, tile, cabinets, countertops, sinks, tub, faucets, etc.). We encountered a few minor bumps in the road and the project ended up taking just a little longer than expected but I have heard stories from others on their projects taking two or three times longer with other contractors so not bad at all. All the delays were outside the control of Ovation. We did encounter an extra cost on some replumbing, but Rick helped us out a bit by giving us a discount in the end. The workers and contractors were easy to talk with, but we did have issues from time to time communicating with one of the workers. It all worked out in the end. Joshua had great attention to detail, and he continually kept us updated on the progress. His assistance in helping us to decide the layout for the shower walls was important to our satisfaction with the bathroom. We were told that they would clean up a bit at the end of each day but that seldom happened on our project. We have a couple of minor issues that I am sure will be taken care of soon but overall, a better experience than I expected. We will contact Rick and Ovation Restoration for our next project and would recommend him for your next project. Thanks again Rick."

Basement Remodel questions, answered by experts

Adding an extension or addition to your home costs more than a loft conversion in all but the rarest cases where the home's structural integrity is lacking. Because a home addition requires a new foundation section or significant structural upgrades to handle a cantilevered portion, the cost compared to almost any loft conversion is significantly greater for the same square footage.

Yes. Renovating your basement has a return on investment (ROI) of 75%, meaning your remodel investment will significantly increase the value of your home. Besides the ROI, your family can enjoy a larger, more usable space while you live there. 

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.

Envision the type of bar experience you'd like to create for your guests. For example:

  • Does your basement have enough finished space for bar stools or seating?

  • What type of additional lighting would set the tone for the room?

  • Are there basement windows or an HVAC system?

  • Do you need new plumbing in your basement for a proper wet bar?

  • Could you be happy with a built-in wall cabinet bar rather than a full-scale wet bar?

Rebar is an essential part of reinforcing a basement floor, as not having it can impact its structural integrity. It helps absorb the tension factors that contribute to cracks in your floor and strengthens its load-bearing capabilities by evenly distributing the weight. Not including rebar could lead to an unstable floor, so don’t skip it!
