    "TL:DR - Pegasus is a top tier contractor and I will absolutely go to them for any and all work in the future. Reasonably priced with above and beyond service/care and correct/proper/by the book workmanship across the board. It's not the cheapest, but if you want it done right, it's a top notch deal to work with Pegasus. This review is a bit overdue as work finished over the summer a few months ago, but I cannot recommend Mike and the Pegasus team enough. After meeting with several contractors for my load bearing wall removal project, I felt the most secure and comfortable with Mike and chose Pegasus for the work. They were middle/upper middle of the pricing but I knew I was in good hands. I had a comparatively small project to what they normally do, but Mike didn't hesitate to help me take on this project after discussing my needs and wants, and for that I'm truly grateful. Speaking with him, you can just tell he's a stand up guy. Mike was professional and always attentive and detailed in explanations, which I appreciated. Communication from the whole team was excellent throughout the project and they were accommodating with my schedule needs. Knowing our pet situation and also that my wife had a night shift schedule, Mike always remembered and always made sure all of his workers and subs were aware to minimize disruption. Of course, major housing projects of any size are difficult to deal with and ours was an ordeal with some surprises, but it was definitely unavoidable and impossible to have figured out prior to work starting. Pegasus made it as painless as possible and gave us time to figure out the best path forward and guidance on any issues or concerns we had. Ultimately, I have zero regrets with starting the project, choosing Pegasus, or with the final results. Everything came together and our project came to completion before the projected date. Definitely give Mike and his team a call if you're looking to do any sort of work."

    "We were in need of a major master bathroom remodel and were referred to Horizon Construction by a friend who had been extremely please with their master bath remodel. The owner, Mark, came out on time and gave us many suggestions based on the space we have and an estimate of the cost. We visited their show room several times to make our selections and were ready to begin. The workers all arrived on time and Mark supervised the project from start to finish. Mark was meticulous in making sure all work was completed to his and our satisfaction. The result is a beautiful travertine and quartz bathroom that we will enjoy for many years to come. We highly recommend Horizon Construction and Remodeling and will use the company for other remodel projects in the future."

    "Have done multiple major renovation projects with Ignacio and IGS Construction over the years. They are always there, never change the budget, no hassle, no sales, finish in great time, just straight-forward, honest good people. I love the kitchens, bathrooms and exterior work Ignacio has done for me. Not only does he have an amazing eye for design and layout, he cares so much and is so fun to work with because he works so hard and loves what he does. I actually look forward to doing remodels with them! Since my background is in design, I know what I am seeing, and they do beautiful work. Very easy for me to recommend this company. 10 stars."

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.
