    We are repeat customers and Alex and Svetlana continue to do excellent work promptly at very reasonable prices. This time in addition to window replacement they also did some outside painting of metalwork, inside waterproofing and finishing of our basement apartment and painting. The work progressed rapidly without delays and their crew always kept things very clean and dust to a minimum. They work collaboratively on discussing options for solving problems that arise during any remodeling of an older building. We recommend them highly and will be using him again in the future.

    I worked with John James Properties to remodel my son and daughter-in-law’s bathroom. I was doing this long distance and John James Properties made a difficult situation easy. They were very communicative throughout the process, which went smoothly. The result is beautiful! Well done and in exactly the time frame they stated. Thanks!

    Jason and his team were extremely helpful throughout the whole process of renovating two bathrooms in my home. They walked me through every step, and ensured I got the bathrooms I've been wanting. I searched between many different companies before starting my remodeling projects and Hometech was the best by far. The whole team is extremely attentive, professional, and caring in general. it was a pleasure working with them and I would highly recommend for any remodeling projects.

    The work was done the next day. The contractor NEEDS to inform the customer of all that needs to be done before giving a price. Don't wait and call after leaving to give you a list of other problems that he forgot to tell you. So far, the roof is not leaking as of 2/20/16. He does have an outgoing personality.

    I hired AHI, LLC Oct. 18, 2021 to perform renovation of standard size bathroom that was really do for an upgrade. Both the construction contractor Omar and project manager Pam came out to review the work that needed to be performed and wrote up the contractor accordance to what I wanted to have done. I gave a time for them to report on site and Omar came on time each day as requested. We discussed how I wanted certain things to be placed. Pam worked with me with picking out the floor tiles and backsplash. She was very patient as we looked for the perfect tiles as well as selecting a paint color. Pam and Omar coordinated with the electrician and the contractor to perform the tub restoration which turned out looking brand new. If there were any issues with the construction of the project, I called Pam and she made sure that it was taken care of before the final punch list; job completed on Nov. 15, 2021. I would hire AHI, LLC to perform other projects.

    We worked with Banks & Son in 2021 to renovate our first floor. From the very beginning, Sam Banks was responsive, helpful, and courteous. When I contacted him, he replied the same day, offering references from recent jobs, and was flexible as to meeting time. Throughout construction he was hands-on with his workers and met weekly with us and our architect to make sure everything was going smoothly. When we ran into problems like very old plumbing or supply chain issues Sam promptly provided options to solve the issue. His workers were tidy, competent, and professional. It was obvious that they had good communication with Sam and his foreman. We were dubious about being able to renovate during a pandemic, but Sam was very well connected with suppliers and when there was a backorder (specifically, there were supply chain problems with procuring cabinets) he was very flexible about making deliveries and finishing up around our schedules. In the end, the finished product is GORGEOUS. Sam and his crew produced a beautiful, well-crafted, renovation for a reasonable price with minimal disruption to our family. They gutted the kitchen, knocked down a wall to join it with the dining room, raised the floor in the den, created two new doorways to improve flow through the entire first floor, and put down new, hardwood flooring throughout. They also installed a gas line, moved radiators, replaced antiquated pipes, created a special alcove for a treasured neon sign, and rewired the entire kitchen and dining room. They completed this project in under seven months which would have been sooner if not for pandemic glue shortages. We honestly cannot say enough positive things about Sam and his crew. If you want a beautiful renovation with pleasant, professional, highly skilled craftsmen to work with, Banks & Son is your contractor.

    This is one of the best experiences I ever have had with an installation/repair service. The owner was extremely responsive to my needs, making several efforts to reach me to schedule the job. The young installer arrived early, was exceptionally pleasant and polite, installed the new dryer after removing the old one and cleaning the area. He was quiet and efficient and made a point of showing me everything I needed to know once the dryer was installed. I can not recommend this company highly enough. Dr. Gail C. Weigl

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.
