    "Chris is a pleasure to work with: He came when he said he would, explained what he thought needed to be done, returned and fixed the problem--and explained again what he had done and why. We are very pleased with his work, feel his prices were fair, and will hire him again. He cleaned during and after each project. We also gave him some more jobs to give us an estimate."

    "We used Mike as a general contractor for our commercial store ReLeaf Cannabis and we couldn't be any happier with how things came out. Mike handled everything quickly, efficiently, and helped educate me and my team along the way. He's very knowledgeable of his craft and was always keeping an open line of communication with us regarding progress and the next steps to expect. Mike handled communication with the twp and organized the inspections for us. It was a very seamless process working with Treglown Contracting!"

    "Tammy Jones 1 review My husband & I couldn't of asked for a better group of people to do the work on our home. You see our experience isn't quite like many other's. Due to solar panels causing leaks in our roof for far to long, we had extensive damage to our whole home. Frank, John, Dan, Mike, Kenny, Dom, Dave, Dave, and so many more. We had the best experience and top notch service. From the replacement of our roof to them referring a mold remediation company, to demoing our house, and then putting it all back together, the guys Marty, Frank & Chris who painted, all of it was such a great experience. Don't let anyone ever tell you there aren't hiccups in construction either, because there are, but all of those we're taken care of professionally and executed quickly. We are looking forward to them coming back in a few months to do our kitchen. If you are looking for a company that truly cares about their customers, then look no further. We highly recommend Daniel Robert Remodeling for any and all your remodeling, repairs, roofing, and anything else in their expertise. Thank You To All Of The Daniel Robert Team......You All Rock â ¤ï¸ ð ð Love Mike & Tammy Jones"

    "As a realtor, my clients often require handyman services to help prepare their homes for sale. I have referred LMA (Lou) to my clients several times and have received great feedback on the quality of his work and competitive pricing. He listens to the client's needs, contributes his thoughts on possible solutions, and delivers superior results. Lou is reliable and courteous, which makes him my "go to" guy when recommending his services to my clients."

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.
