    "This was our second major project with Primework Construction and we couldnâ t be happier. It was so easy for us, Ben and his team handle everything. They took care of the architect plans, the engineering, permits, facilities for the crew, and clean up. They worked within our budget and completed the project ahead of schedule. They really go out of their way to treat us well. We highly recommend using them for any of your projects, big and small."

    "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!"

    "Unleashing the magic in my kitchen was made possible by IY Development & Renovation! From concept to completion, their team worked wonders. The attention to detail in the design phase was impressive, and the end result is a kitchen that not only looks stunning but also functions seamlessly. Kudos to the IY team for turning my culinary dreams into reality!"

    "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!"

    "Tomer did an excellent job of project managing the following: 1) replacement of a bathtub with a walk-in shower; 2) replacement of the bathroom sink, countertop and side splash; 3) replacement of the door to the bathroom; and 4) replacement of the ceiling light/fan. He stayed in close communication throughout, beginning with providing an estimate and including applying for permits and inspections, and checking the progress of the work. Roberto came up with an innovative pattern for the shower tiles that I really love, provided good advice on the products I needed to purchase, e.g., the shower drain and the ceiling fan light, and picked the products up from Home Depot. He kept his worksite inside the bathroom neat and clean and made sure the pathway to the bathroom along hallways and stairs was also neat and clean after equipment and products were brought inside and taken to the bathroom on the second floor. I am highly satisfied with the work of S and L and plan to use their services again for my next home improvement project."

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.
