    "This our second time hiring Allen for a remodel project. He did our kitchen in 2024 and it turned out great. This time it was two bathrooms which were completely remodeled. Allen is great to work with. I am always impressed with Allen's clear communication about what the project will involve and his ability to balance the needs of the homeowner with the needs of the project while the work is going on. This is especially important for my spouse and me since we both work from home. Not once did we ever feel like a burden while the work was going on. At the end of each day, the work areas are organized and neatened up so our home was still completely functional on evenings and weekends. I also appreciate how Allen manages all parts of the project. He deals with all the individual vendors and oversees all aspects of the work to ensure quality for the customer. This makes a complex renovation project much easier to cope with and why Allen is always our go to guy for home projects."

    "I recently hired Solid Foundation Construction LLC to replace my carpet with vinyl flooring, and the results are absolutely perfect. I’m a very detail-oriented, high-maintenance client who is rarely fully satisfied — yet this project exceeded all my expectations. The quality of the work is outstanding. The crew worked incredibly hard from morning until evening, moved quickly without sacrificing precision, and delivered flawless results. My floors look stunning, and I truly couldn’t be happier. The owner is also a pleasure to work with — professional, responsive, and genuinely committed to making sure everything is done right. I would recommend Solid Foundation Construction to absolutely anyone looking to improve their home. Do not hesitate to hire them. I already can’t wait to work with them again on my next project!"

    "When we moved into our newly purchased townhouse in Germantown, Md, we quickly realized that our kitchen is very old and outdated. We spend a lot of quality time in our kitchen and it had to be remodeled. When we met Willis Builders and their amazing project manager, Willie Acosta, we got our own designers and best advisors too. Everyone on their team was professional, courteous, kind, polite and knowledgeable. We are happy with our new countertops, beautiful backslash and kitchen floors. They also helped us fix our deck and bring it back to code and best condition. Thank you guys for everything ❤️"

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.
