Remodels, Deck Builds
"We hired Ruxton and his helper to repair our backyard deck and remodel the front porch. We are happy with his design suggestions. Both men worked hard and quietly. Ruxton was always easy to reach to answer questions and he was easy-going when I changed something. Both structures feel very sturdy when I walk on them. The railings are strong and give me confidence in using them. Ruxton and Chris were very polite and professional. When they were working in front, they brought all packages delivered to the house to the covered door on the backyard deck. The jobsite was cleaned up very well, all I found was 2 pairs of their work boots under the deck. I will hire them again."

The detail to attention, easy and seamless communication and the trust we had for his crew are among the many reasons we will always use Zach for our home projects."

"I recently had the pleasure of working with Keystone Remodeling on a major full house remodel in Bellevue, and I could not be happier with the results. From the very beginning, their team demonstrated a high level of professionalism, attention to detail, and dedication to quality that exceeded my expectations. The project involved a complete overhaul of my home, including updating the kitchen, bathrooms, living spaces, and exterior. Keystone Remodelings team was incredibly communicative throughout the entire process, keeping me informed of progress and any necessary adjustments. They were always responsive to my concerns and worked diligently to ensure that every detail was executed to perfection. The craftsmanship and quality of work were exceptional. Each aspect of the remodel, from the cabinetry and flooring to the fixtures and finishes, was completed with precision and care. The crew was respectful of my home, always keeping the work area clean and minimizing disruption to my daily life. What impressed me the most was their commitment to sticking to the timeline and budget we initially agreed upon. Despite the challenges that often come with a full house remodel, Keystone Remodeling managed to stay on track, delivering a beautiful and functional living space that truly feels like a new home. I highly recommend Keystone Remodeling to anyone in need of high-quality renovation work. Their professionalism, expertise, and dedication to customer satisfaction make them a top choice for any home improvement project. I am thrilled with my newly remodeled home and grateful for the outstanding job they did."

Frequently asked questions
- It’s important that you verify their license is still in good standing. Also keep in mind that certain states or provinces don’t require licensing if the job is under a certain dollar amount.
- You can find a list of your state’s licensing requirements on the HomeAdvisor website. Before you get to work with the pro, make sure their qualifications are current and acceptable to you.
- It is always a good idea to get a copy of the pro’s insurance certificate for future records, and in case anything happens. This is a good way to feel more secure in your home project, and to weed out potential scammers.
HomeAdvisor makes it easy to connect with pros near you. You can read reviews, get quotes and book appointments all in one place.
Depending on the type of project, you may find subtle differences in the hiring process. Here’s a look at task-specific advice.
You can use HomeAdvisor to help evaluate a contractor’s qualifications. We put pros through a screening process, and award badges to high-performing contractors. You can find these badges on a pro’s HomeAdvisor profile, and sometimes, his or her website.
Your research doesn’t stop here. Once you’ve found a few prospective companies, make an call to ask a few questions about work history, licensure and more:
- Have you completed a job like this before?
- Do you have a list of references I can contact?
- When are you able to start the job?
In most cases, the responses you get to these three questions will give you a very good idea of the right pro for your project. If you have more than one front-runner, these additional questions can help you narrow it down.
- How many years of experience do you have?
- What’s your permanent business address?
- Are you licensed to work in my area?
- When did you earn your business license?
- How do you handle warranty service complaints?
- Do you have worker’s compensation, property damage and personal liability insurance?
Any good contractor will answer these questions, and most will appreciate dealing with a client that takes such an active interest in finding good service. On the other hand, if a contractor gives you a hard time with these questions, you probably want to find someone else.
