    "Eli and the team have been amazing. They took on a massive project to make our home accessible for our kid who uses a wheelchair. They built an accessible bathroom, built ramps around the house and made sure the bathroom door was able to accommodate a wheelchair. They gave a visual lift to our house by redoing our floors, modernizing the fireplace and adding recessed lighting. It is worth mentioning that they delivered with VERY high quality and ON time as promised. I highly recommend Alon design and remodeling for your house project. And they did it all while always smiling and being positive - a quality hard to find in a contractor. You won't be disappointed working with them."

    "When it comes to any project related to oneâ s primary residence, while it is an important factor, cost cannot be the only variable one uses to select vendors. One also needs to factor in the relationship(s) into which he/she is entering and how those relationships are going to play out during the construction process. Arguably the most important one of these variables that helps to create a positive relationship â as in any relationship in life â is communication. With Lavan, we absolutely made the right decision. Their communication was candid and valuable, based on their knowledge and experience in not only construction, but interacting with the City, vendors, and other trade-partners involved in the project. Their many outstanding suggestions, bringing to our attention things we may not have considered on our own, allowed us to navigate potential pitfalls that could have impacted schedule and/or budget. They took our existing plan(s), provided constructive, nuanced opinion based on their years of experience and helped us to make the best, most informed decisions. Beyond that, their workmanship is solid. They are committed to ensuring the final product aligns with your vision(s). They genuinely care about the quality of the product they install and the subcontractors they choose to perform the actual installation, treating your home as their own."

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.
