"I am so thankful for choosing blue rock remodeling! Could not ask for more! I bought my house in a pretty bad shape I had a couple of companies come to give me different estimates but this company came and gave me such a beautiful idea the work is gorgeous, the prices were fair and I would recommend them to my friends and family."

"I recently hired Solid Foundation Construction LLC to replace my carpet with vinyl flooring, and the results are absolutely perfect. I’m a very detail-oriented, high-maintenance client who is rarely fully satisfied — yet this project exceeded all my expectations. The quality of the work is outstanding. The crew worked incredibly hard from morning until evening, moved quickly without sacrificing precision, and delivered flawless results. My floors look stunning, and I truly couldn’t be happier. The owner is also a pleasure to work with — professional, responsive, and genuinely committed to making sure everything is done right. I would recommend Solid Foundation Construction to absolutely anyone looking to improve their home. Do not hesitate to hire them. I already can’t wait to work with them again on my next project!"

"Jimmy Jimenez is a very honest person. He was extremely flexible all with the many changes we wanted as during the renovations. He worked around our schedule. He did a complete gut of our kitchen and master bathroom. Did a fantastic floor tiling in both areas. The back splash for the kitchen and shower came out great!! He also added a guest powder room, re-finished the wood floors, painted the entire house. We also had recessed lights and ceiling fans installed. He removed the long wall between the kitchen and the family room and made the area so much bigger. Also installed (5) roman pillars in the dinning room and the living. He also did some plumbing work. Jimmy did an excellent job for us. We are really pleased with his work. If I ever want to make any changes again, I will not hesitate to hire him again."

"We were long overdue updating our bathrooms and our kitchen was far from what we envisioned our dream to be. Scott and his team at Abode Construction listened to our concerns with the current build and what our vision was for the future. From day 1 they were easy to work with, always ahead of schedule, and completed work that far exceeded our expectations. I cant wait to use the Abode team again."

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.
