They demolished everything, then put in new tiles for shower wall and floor, changed the tub, replaced all faucets, vanities, lights and painted the rooms. They are professional and patient, they attend to my requests and give suggestions. The job has been completed on time and in good quality. Will let them do my floor next year. Thank you!"

    "About a year ago I moved into a new home that had a screened porch with a beautiful view. I had left behind a traditional constructed porch that was enclosed and had casement windows. My white wicker furniture was waiting for a home, but hadn't been constructed to deal with rain and snow. I proceeded to get four estimates - two for a traditional porch structure and two for a sunroom structure. All came in amazing close in price. I decided on the Garrety Glass Betterliving sunroom option due to the openness of the view, the professionalism of their staff, the quality of their materials, and recommendations by former customers. I was extremely pleased with the entire process. The first thing I noticed was their concern for the stability and safety of the porch, which was on wood pillars, to be able to sustain the additional weight of their high quality and heavy glass. They were the only group to carefully assess the current posts and point out some major splits. They also were concerned that two posts may not meet building codes due to the distance between them. I was glad that remediation was addressed at the onset and included in their estimate, and that I could be comfortable with guests and grandkids being safe on the second story structure. The quality of the total structure, I felt, definitely exceeded that of their sunroom competition. The salesman worked with me on the details I wanted including the white framing to go with my wicker, the ceiling beadboard, reusing the current ceiling material to enclose the insulation under the porch, and putting damp resistant drywall as well as window/door casing to have the porch match the interior rooms in the house. Also included was a mini split HVAC system to make the room usable year round. Not only was I impressed with the company's materials, the two young men who did the construction were wonderfully collegial, organized (they gave me a daily list of what they would be doing for the two weeks of construction), flexible, attentive to detail, and excellent craftsmen. I would highly recommend them to anyone building a porch; the project was completed when scheduled and the cost was as agreed upon. I now have a beautiful room with an overall unobstructed view of the area along with breathtaking sunsets. I'm very happy with the finished porch and would highly recommend Garrety Glass Betterliving sunrooms as well as their team of salesmen and carpenters."

Jerry was our primary point of contact and he was extremely customer oriented throughout the entire process. He came by every day that work was ongoing and he was in contact with us in person, by phone and via email. All of the subcontractors brought in (demolition, electrician, plumber, drywall installer, mud and sanding, painter, HVAC) were all extremely professional and the quality of work was first rate."

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.
