Common Costs of Home Add-ons and Renovations

Your renovation’s scope and its complexity are huge factors in the price your home improvement company might charge. If you’re looking to add an additional room onto your property, for instance, your contractor has to dig, lay a foundation, build the new structure, add plumbing and electricity, then apply finishing touches such as paint and drywall. The national average for home additions is about $46,700.

A full kitchen renovation runs $13,500 to $38,200, and remodeling a basement can cost $12,200 to $33,300. An overall home remodel runs anywhere from $20,700 to $73,100.

The more difficult your job, the more you can plan to budget for it. For example, adding a second level to your house is costlier than adding a room on the first story. Adding a room is usually less affordable than renovating a pre-existing space. Upgrading a kitchen, which may necessitate electrical and plumbing work as well as carpentry, might cost more than a new entryway.

The easiest way to find out how much your renovation job may cost is to get quotes from local remodeling companies. Get in touch with prospective renovation contractors in Seattle to begin.

Kinds of Projects Neighborhood Home Improvement Businesses Help With

Home improvement contractors provide all types of services to help upgrade or revitalize your home, from entire overhauls to simple improvements.

Expanding the Home’s Size

Home improvement specialists might build additional rooms or other structures onto the home. For example, some home renovation contractors are more experienced in the addition of garages to properties that formerly only had carports. Other common add-ons include extra bathrooms or a bigger living space or kitchen.

Enhancing Indoor or Outdoor Elements

Often, your home requires a touch-up and not a whole new room, and home renovation companies can help with those types of jobs too. This might include hanging and framing doors, adding cabinetry, updating trim and molding, installing new windows, or replacing lighting fixtures.

Contractors don’t always perform all of the services that are possible with a home upgrade. A lot of contractors sub out work to others when it requires certain skills. For example, if you are planning a basement upgrade that includes theater seating, your remodeler may subcontract any electrical work to a credentialed 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.
