"We were very happy with Randy and his work. He did an excellent job and we couldn't be happier! Our job was a fairly large one, replacing carpet with new, finished in place hardwoods for almost 3700 sq feet. The job followed the timeline that Randy gave us ahead of time, as well as staying to the budget that he quoted us before the job started. When moving our furniture back into the house, a large object was dropped and it gouged our beautiful floors! I was devastated! I emailed Randy and Amber about it, and by the time I got home from work the next day, he had come over and fixed the scratch for us. That's what I call wonderful customer service! I would definitely recommend Rosell Hardwood."

"Snoqualmie Construction Services helped build an amazing home office in a pre-built shed outside my home. They were extremely professional and quickly came out to provide an estimate. I could tell JJ and Dan were excited to help my vision become reality. They gave me a great price and were able to finish the project in a matter of days. I love the results!"

"Marybeth and her crew were great. She stayed right on schedule and anything that was going to be overbudget was always discussed. She's a great resource for not only design but also project management and everything that entails. I would strongly recommend her and couldn't be happier with our selection. It's rare that a company lives up to their name but in the case of New Home Solutions they actually deliver solutions."

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.
