    "We hired David and Noah to do a gut renovation of our home in Santa Monica. We decided to hire them after interviewing six different contractors. From the initial phone call I had with the office I knew these guys were different. We were impressed to find that they were the only contractors to ask that I forward the blueprints we had so that he could come to the meeting prepared. When we met we immediately felt comfortable entrusting our new home to his company. Our project ended up being more difficult than we originally had thought. Some walls we wanted to remove were structural and almost every wall had plumbing. David and Noah, and their entire team handled each surprise like seasoned pros and these challenges did not stop their team from delivering the home we had envisioned. Santa Monica is also very strict with inspections. The office was scheduling inspections every time we needed and was very patient and professional working with the city. The quality of the work has been great and the team even occasionally reaches out to make sure everything is ok. I would not hesitate recommending them. At the end of the day they are really great people with a terrific team. They are professional and they stand by their work."

    "We were in need of a major master bathroom remodel and were referred to Horizon Construction by a friend who had been extremely please with their master bath remodel. The owner, Mark, came out on time and gave us many suggestions based on the space we have and an estimate of the cost. We visited their show room several times to make our selections and were ready to begin. The workers all arrived on time and Mark supervised the project from start to finish. Mark was meticulous in making sure all work was completed to his and our satisfaction. The result is a beautiful travertine and quartz bathroom that we will enjoy for many years to come. We highly recommend Horizon Construction and Remodeling and will use the company for other remodel projects in the future."

    "I am writing this DETAILED review, because I am sure most prospective customers will welcome and appreciate it. BACKGROUND: How many times had we seen TV shows about vendors winning a job, then disappearing half-way through the project, leaving the homeowners with a mess everywhere. We were hyper-sensitive to this fact, so we really did our due diligence. We interviewed five separate contractors. Opulent Design Build (ODP) got our business, because: 1. They thoroughly reviewed our project plans and provided guidance (without making us feel like an open ATM). 2. They were the ONLY vendor to line-item each major project item cost. 3. ONLY vendor that came in upfront and said all material was cost+ 20%. Nothing more and nothing less. 4. They even welcomed us purchasing some of the materials on our own, saving us some money. For example, when we saw toilets on sale at Home Depot, we purchased three, saved the receipt and they deducted it from the project cost. 5. Reputation: After reviewing ODB's business records and job history, they truly out-shined the rest. We were confident they would still be in business throughout the project, unlike some other vendors that showed up with questionable records and spotty history. 6. Mgmt availability was impressive, in that when we had some questions and I requested to speak with the owner to wrap things up, he met with me the next day. Not many owners take personal ownership of their business like Eddie. PROJECT DETAILS: After a month of reviewing contractors, we were very tight with our timeline, as we had 2 months to get this full-house major remodel completed. a) Payment Schedule: ODB came to us with a payment schedule aligned to project milestones, something you don't often find in the industry. Often vendors just expect their payment on a due date, regardless of whether or not they completed their previously-indicated project tasks. We had eight payments set up, with the first being larger to allow for them to buy materials needed to start the project. Everything worked out as promised and we honored our side by making timely payments too. b) Workers: Right from the start, their Senior Construction Manager, Johnny S. was onsite managing the start of the project. To my surprise, he would show up onsite almost EVERY DAY in the morning to answer any questions his team might have. One thing we loved about Johnny was that we had direct access to him too, via mobile phone. My wife and I would easily text him or call with any concerns or questions. His response time was usually within the hour. The other thing that impressed me is that consistently, we had 2-4 guys on our job site SIX days a week for the FULL two months. In the beginning, Johnny even had 6-7 guys working for a full two weeks, since most of the heavy lifting fell into those initial weeks. Oh, and these guys were really great too. Very respectful of my family and property. No smoking, drinking or profanity. Although many spoke Spanish, there was always someone their that could converse in English if needed. c) Work Quality: Johnny told me that the reason all his guys were super talented in their respective areas is because he is extremely focused on hiring only the best. These guys were truly amazing, and the quality really came through in all aspects. Johnny would back me up too, if we mutually agreed that something was not looking right and he would instruct his guys to do it over, regardless of the additional time and money required at his expense. d) The Unexpected: Three-quarters of the way thru the project, after all the walls were finished and painted, we developed TWO slab-leaks. Johnny calmed me down and instead worked with me to ensure that the problem got resolved in a timely fashion and a reasonable cost. We cannot recommend this company enough! HIRE THEM - PERIOD! :-)"

    "Super happy with our addition to IGS Construction! From start to finish, the process went smoothly. All the city inspections passed easily and quickly and the inspectors liked what they saw which gave us a lot of confidence along the way. The work was done in good time too. This was a very nice surprise for us because both my husband and I had expected it to take much longer and be more complicated. I am sure it was, but somehow they made it seem easy and we had no big issues. This was a build-or-move situation for our family, and so we could not be happier with our decision. After hearing of other peoples experiences with other contractors, I would say the thing that makes a difference about IGS is they have the skill and experience but they also care a great deal and make sure that you are satisfied. We refer them to everyone who asks us."

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.
