    Posted by Catherine F.on 30/11/2022

    We are so pleased with our new shower, and the professionalism of the entire West Home staff from beginning to end of this project. Robert was an excellent, informative consultant when we were first exploring the options available to us, and our installers Fabio and Marvin were careful, detail oriented, and so polite. They clearly take pride in their work and we can see why. I recommend them and I would hire them again myself.

Services Provided by Area Remodeling Businesses

Home remodeling companies provide all kinds of services to help upgrade or enhance your home, from entire renovations to simple improvements.

Expanding a Home’s Square Footage

Home improvement specialists may construct additional rooms onto a home. For instance, some home renovation contractors specialize in adding garages for properties that previously only had carports. Other common add-ons include additional bathrooms or an extended entertaining area or kitchen.

Upgrading Indoor or Outdoor Elements

Sometimes, your property needs an update and not a whole new room, and renovation providers can help with those sort of jobs too. That may include framing and hanging doors, hanging cabinetry, upgrading trim, hanging new windows, or replacing lighting fixtures.

Renovators don’t always provide all of the services that are possible with a home renovation. Many remodelers sub out work to others when the project requires certain skills. For instance, if you are planning a basement refresh that includes theater seating, your service provider may sub out any electrical work to a licensed electrician.

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.
