    "I had a great experience with Tanner and the whole team from start to finish. I came to them with an idea for an outdoor office now that I'm working from home. After they came out and surveyed the property, we went over some design options to ensure it had what I needed, not just what I had them bid on. It wasn't an upsell either - we made changes that lowered the overall cost while increasing the durability of materials by sacrificing an aesthetic design choice I had made earlier, not realizing it was a large cost factor. The scheduling was great - they showed up and left when they said and kept the site clean between work days. I was able to watch them do a lot of their work, and it was done with skill and quality. The final product looks amazing and I'm already planning two other projects where I'm going to have them bid."

    "Breyden is very on time and on schedule with everything! He is very organized and has amazing communication skills. I recommend him and to everyone I know! The quality of his work speaks for itself, he pays attention to details and is a perfectionist. I have hired his for multiple projects and also my guest home addition! He is my go to contractor and now I hire him for any home projects. He goes above and beyond and also is a very honest professional."

    "The construction process went extremely smoothly. The crew was professional, efficient, and kept an incredibly tidy worksite. They took the time to understand my vision for the addition and made helpful suggestions to optimize the design and layout. The craftsmanship of their work was outstanding - the new second story blends seamlessly with the original structure. Perhaps most impressive was how quickly they were able to complete the project. I was expecting the addition to take months, but Umbrella Bill LC had it done in just 10 weeks. This was a major time and cost savings for me."

    "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."

    "He did wonderful job with my floors! I had someone come in one year before he did and installed linoleum flooring in my bathroom but they absolutely ruin my whole floor, and I wound up getting a lot of water damage. Marco came in and did a Spectacular job with the same exact flooring."

    "They did a remodel of our laundry room and did an immaculate job! Worked closely with us on design suggestions and gave good feedback on materials and colors we were thinking and balanced our ideas with theirs. The work was very precise. They take great in the smallest detail and the work is of the highest quality!"

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.
