How we estimate costs

Every QuoteRuler guide answers one question: what does this job usually cost in the United States, and what should it cost where you live? This page explains how we get those numbers.

1. We compare several published sources

For each project we collect prices from at least four independent sources. These include national cost guides (such as Angi, HomeGuide and Fixr), retailer and manufacturer price pages, trade associations and government agencies. We record the exact figure each source gives and link every source at the end of the guide.

Sources rarely agree exactly. They measure different things: some report national averages from contractor quotes, others report ranges from a single market or exclude permits. When they differ, we explain why in the article and report a range that reflects where most sources overlap.

2. We report three numbers

• Typical cost: the range most homeowners pay for a standard version of the job.
• National average: the middle of the sources' reported averages.
• Full range: the cheapest simple jobs to the most complex ones.

3. We adjust labor by state

Labor is the part of a home project that changes most from place to place. Each guide states what share of the total is labor, based on its sources. We adjust only that share using the U.S. Bureau of Economic Analysis Regional Price Parities (2023), which measure how price levels in each state compare with the national average. Materials are treated as national prices.

This is a model, not a survey. It is good at showing how a state compares with the national average. It cannot see local factors such as a shortage of licensed contractors, local permit fees or a recent storm that raises demand.

4. The calculator and quote checker

The calculator adds the cost ranges for the options you choose, applies quality or complexity factors, then applies your state adjustment. When you enter a quote, we compare it with your estimate:

• More than 15% above the top of your estimate: we suggest asking for an itemized quote and getting more bids.
• More than 20% below the bottom: we suggest checking what is excluded and confirming licensing and insurance.
• Otherwise the quote is within a normal range.

5. What we don't do

We don't sell leads, we don't take payment from contractors to appear in a guide, and we don't publish invented reviews or testimonials. Our numbers are informational. Always get written quotes from licensed, insured local contractors before you decide.

Updates and corrections

We review prices at least once a year and when a major source updates its data. If you think a number is wrong, tell us through the contact page and include the source.
