1.0 Pete E. Spokane, WA

If I had only asked a general contractor friend of mine for a referral rather than Angi, I would have saved myself hundreds of dollars. I didn’t realize their employees worked on commission. They charge $ 80.00 to come out to give a bid. They billed me $885.88 for one hours work. After I returned their survey complaining about their obscene prices they issued a $188.00 credit. I will never have Mainstream do work for me again and I will certainly never recommend them to anyone.

Mainstream has done an amazing job. This was a large hvac job, and they have done a great job getting it done in a timely fashion.

5.0 Patrick J. Spokane, WA

Mainstream installed an undermount sink to replace one that another contractor broke. Mainstream did a great job. Their ability to do the job quickly allowed me to sell my house on time.

5.0 Clive T. Spokane Valley, WA

The carpenter and his helper did a fine job on the drywall repair and shower door installation. It all looks great, just like in a high-end new house. Recommended!

5.0 Juana/elsa P. Coeur D Alene, ID

They were great. Everything was done on time. The job required an electrican to arrive which he did. So the plummer and electrican worked together so the job was completed in one day.

4.5 Becky L. Spokane, WA

Excellent company to work with. Very customer service oriented, prompt and efficient work by service technicians. Highly recommend this company.

HomeAdvisor allows Service Professionals to post information about themselves and their business on their profile. HomeAdvisor does not review or verify the information representations set forth in those profiles as they are self-reported by the Service Professional.

HomeAdvisor verifies state-level licensing where applicable - note: some states require local or county level licensing and you should verify whether or not your pro is properly licensed.
To find more licensing information for your state, visit our Licensing Requirements page.

Seal of Approval

What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.
  3. Verification of State Business Filings
    For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
  4. Criminal Records Search
    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
  7. Legal Search for Civil Judgments
    We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them.
  8. Liens Search
    We use 3rd party data sources to check the principal/owner of the business for liens placed against them.
  9. Identity Verification (SSN)
    HomeAdvisor verifies the social security number(s) of the owner/principal for identity check purposes. This check applies primarily to smaller business entities.
  10. Identity Verification (Reverse Phone Lookup)
    We conduct a reverse business phone lookup to identify records matching the phone number information provided by the business.
