Methodology and Sources

Our guides are a rigorous, comprehensive, and trustworthy reference for homeowners and potential home buyers. This page provides you with information about our editorial process. We also include a selection of our most important sources.
Our Content cost guides provide national average costs for several home remodeling projects and aim to present all the information necessary for our users to make the best decisions about their homes and properties. We have also created other comprehensive resources, such as comparison guides and a home remodeling glossary to answer every question that homeowners, potential home buyers, and home renters may have. Additionally, the blog is a space for homeowners, industry professionals, and even home buyers and sellers to keep up to date with the latest home construction industry news, trends, and helpful advice.
Since 2008, our mission has been to make the tedious process of home remodeling easier. We strive to provide the best information for consumers, and we pride ourselves on being:
Instructive provides cost guides, comparison guides, trends reports, articles, and custom illustrations to help users gain a deeper understanding of home-related projects.
Authoritative content is written by cost researchers and writers with provable experience in the home improvement industry, and constantly reviewed by industry experts.
Unbiased is a vendor-independent resource. We do not have ads on our site.
Editorial Process

Fixr employs a team of specialized writers and cost researchers who are subjected to a rigorous selection process, where they prove not only their experience in the home remodeling industry but also their research and writing skills. Most have worked as contractors, designers, interior decorators, and architects for years, and they use a wide variety of professional resources, which are listed below.

These writers and researchers work closely with the editorial team at, who also have experience in the home remodeling industry. Our team edits, proofreads, and checks that all the prices and information at are consistent and provides all the necessary information to homeowners and potential home buyers.

Once the guides and articles are written, their credibility and comprehensiveness are strengthened by the reviews and feedback of our industry-leading experts, who ensure that our content is accurate, up-to-date, instructive, and backed by current research. Costs are reviewed yearly and usually remain up-to-date until the next year. If any radical change occurs in the price of one project or material before that period of one year, the editorial team will inform the reader of the changes in all the cost guides affected.

Our editorial team also works closely with the network of 90,000+ local contractors, who provide a unique source of information for our cost guides. When contacting contractors and local service providers to ask about prices, we choose cities where the cost of services are in line with the U.S. national average, such as:

Ithaca, NY; Sarasota, FL; Cincinnati, OH; Dayton, OH; Iowa City, IA; Montgomery, AL; Tyler, TX; Houston, TX; Rochester, NY; Atlanta, GA; Birmingham, AL; Austin, TX; Dallas, TX; Tulsa, OK; Durham, NC; Marietta, GA; and Raleigh, NC.

This means that we do not show local costs for sites that are significantly more expensive than the national average, such as New York City, NY or Boston, MA, or cheaper like Omaha, NE or Harlingen, TX.

Home Improvement Experts works hard in collaboration with top-leading experts in the home improvement industry who write, edit, review and contribute to our cost guides and trends reports.
