    "This is what I posted. A kitchen and bath remodel can be a major upheaval in a home, so having an experienced and conscientious firm and crew is essential. Tomer Edelson of S&L worked with us on the planning and made several suggestions that were helpful in laying out our new kitchen within the bounds of a 50 year old house. Tomer brought in Amy from Canaan Cabinets, who furnished the cabinets to discuss what was important to us make suggestions, define what can and cannot be done in our budget, and of course bring samples. Because my wife and I are both north of 60 we needed the additional perspectives of those much younger than us and Tomer was part of this group that helped. This careful and collaborative planning resulted in a new kitchen that married our traditional tastes (wood grain cabinets) with modern cues (subway tile backsplash, quartz counters, and spice drawers) in a cohesive manner and the finished product was beautiful. The workers, Roberto (lead) and Domingo, were skilled and efficient. They also got on well with our pets (dog and cat), which we found a major plus. The entire project was completed in 3 weeks, which is exactly what Tomer estimated. The few little changes we asked for and flaws we noticed were addressed and corrected without arguments or change orders, Also important was that Roberto and Domingo cleaned up the work area every day, and followed coronavirus protocols. For price, S&L was very competitive though not the cheapest. The operative word from our perspective is we received terrific value in materials, craftmanship, planning, organization of work, adherence to schedule, and safety. We highly recommend S&L Remodeling and Tomer Edelson"

    "My backyard project included installing a new redwood side fence, replacing old redwood fence boards on the back fence, removing the lawn and brick walkway and installing a new concrete patio in those areas, installing a new wood safety guard rail and installing a new ADA compliant handrail to use when walking down the backyard steps to the laundry room. I am so happy and pleased with the results! Babylon Builders transformed my backyard into a beautiful, safe space that I will enjoy for many years to come. It was a pleasure working closely with Ron on my project. Juan and his crew performed excellent, outstanding work and they always cleaned up very well. I feel so blessed and fortunate that I found Babylon Builders. I highly recommend them! Many thanks for a job well done, Babylon Builders!"

    "I had a great experience working with Mike, Ken, Keren and the Palm Construction crew on the remodel of my 1 bedroom, 1 bathroom apartment in San Francisco. They did major work on my bathroom (completely gutted it) and kitchen (beautiful new cabinets and countertop/backsplash) with updated plumbing and electricity. They also installed recessed light in all the rooms and updated the floors throughout. My apartment feels so much more spacious and light, and I love being home. Every person I interacted with was professional and kind. Mike was extremely patient with me and my countless questions along with mini anxiety attacks as this was my first remodel. Ken was also very communicative and between him and Mike, I felt like I was in the care of friends. The designer they work with, Keren, is also amazing, kind and has fantastic taste. One of the most impressive parts (among many) is that they were able to complete all this work in six weeks, all up to SF code, and would have been faster had shelter in place not started. I highly recommend Palm Construction and would work with them again in the future!"

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.
