"Erick is a truly good man who stands by his word/price. I had two bathrooms remodeled and I am thrilled with the end result. Erick made sure that any inconvenience to my family was minimal and at the end of every day their clean up incredible. After getting three other estimates, I had Erick come over to estimate the price and his price was 20% lower than some of the other estimates. Erick is my go to contractor, I trust him and I intend to have him do some more work this spring. Feel safe hiring Erick, you will not be sorry."

"We hired LionHeart Finish Carpentry for an interior painting project, and we are very happy with the results. Gustavo and his crew were punctual, respectful, and careful with our home. They protected the floors and furniture, fixed small imperfections before painting, and left the rooms looking fresh and professionally finished. The quality of the work made a big difference in the appearance of the house. We would definitely use them again."

"I needed plans for a two-car garage of a certain size and roof pitch. I could not find stock plans of specifically what I wanted. Richard was very prompt and helpful, produced the plans and arranged for an engineer's stamp."

"We are trying to sell our house and are on a strict timeline. Max responded to my inquiry immediately and was very professional. He was able to come to our house the next day, and start the work within 48 hours of our inquiry. Him and his team were efficient, and gave us peace of mind going into the selling of our house. Could not recommend Makyson Building more!"

"To be fully honest, at first I was a little skeptical, as I am with most contractors, but they came in on time, were very clean, and were punctual about the things I asked for and needed done. The crew was efficient and the work was done correctly. They even helped and built my elderly neighbor a garage bathroom after seeing the work at my house. I definitely will have them back to build my ADU for my in-laws."

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.
