5.0 Stanley R. Weston, WV

Great Job!!

1.0 Tim A. Rivesville, WV

They did show up in a timely manner but the only real work was done by my spouse, she was asked to look up the error code on our computer and they did read it but only told her what we had already wrote down for them. She was told it needed a main board at a cost of $600+or- plus labor, she asked them to provide a part number if possible and she was told they would look it up and she could call to get it and she did so the following day. No number and the person she spoke to had no idea what she was asking for. My spouse was told they would call back with the info and they never did. I worked many year ago with ac/hvac but have no means to diagnose modern mini split units but I did look at the mother board and found a schematic in plain view under the top of the unit, they had this off as well. It showed three fuses which are simple to test with a multi-meter and I did so and found a bad fuse replaced it and the unit works as new! No I would not recomend them at least for this type of unit, sorry but $93 for a service call would be fine if they just checked a fuse or two but that aparently isn't done anymore and no return call? Not doing business with them again. PS I work days and could not be home for the service call but my spouse is very intelligent so I trust she knew exactly what happened and acted kindly with an open mind and had it cost $93 for service and a .75 cent fuse I would have been fine but that did not happen.

5.0 Tom U. Morgantown, WV

Mike, the tech, had been doing this for 26 years and really knew what he was doing. I was worried about what I was going to get, never having heard of the company, but they were great.

Response from Company:

Thanks Tom! We appreciate the opportunity to service your home and look forward to working with you again!

5.0 Rebecca N. Parsons, WV

They came immediately after I called. They worked diligently and resolved the sewer problem expeditiously. They worked in below freezing and inclement weather conditions without complaint and worked for many hours before the problem was resolved and job completed. Simon-Graham Plumbing from the owner to the men doing the work were professional, courteous, respectful and they charged a fair price for the work that was done. I would and have recommended their business for their services.

Response from Company:

Rebecca, we truly appreciate your kind words! Thank you from all of us here at GSP!

5.0 Shawn G. Clarksburg, WV

very friendly and they know what they are doing

Response from Company:

Thank you Shawn!

5.0 Richard R. Grant Town, WV

Incredibly professional. On honest, time, knowledgeable, pleasant, fair. I can't recommend these guys enough. He had the problem accurately diagnosed and fixed without upselling parts. It was an old $2 switch, with no attempt to make the repair take longer or more expensive. You won't be disappointed, and you're problem will get fixed correctly and honestly. Pretty rare qualities these days. A++.

Response from Company:

Richard, we truly appreciate your kind words and rating! Graham-Simon Plumbing is happy to help anytime you're needing our services. (:

5.0 Brian and debra K. Camden, WV

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.
