We hired Master Builders Const NW LLC as the General Contractor for a very large Standard 203k HUD project. Master Builders was unable to complete our 230k project because Bill refused to acknowledge the Specification of Repairs (this document defines the scope of the project) which he signed via DocuSign at the project’s inception. Accountability is not one of Bill’s strong suits, and it runs downward throughout his company. This made an already stressful experience very, very frustrating as well.
It became beyond evident that Bill and his crew could not complete our project as agreed upon and he ended up quitting and accusing someone of changing the SOR documentation (even after the lender provided him with proof of his signature). After he quit the project, he was then asked to provide electrical permits for the work that had been completed so we could move forward with another contractor. Bill replied via email:
“…. There is nothing in our invoice that would require additional permits. If there was anything that would have required additional permits we would have made sure the permits were obtained.”
Well, the electrical inspector from Washington State L&I disagreed with Bill and issued three citations to Master Builders Const NW LLC:
- Failing to obtain an electrical/telecommunications work permit (RCW/WACWAC 296-46B-901 5)
- Employing an individual for the purposes of chapter 19.28 RCW who does not possess a valid certificate of competency or training certificate to do electrical work (RCW/WAC19.28.271)
- Offering to perform, submitting a bid for, advertising, installing or maintaining cables, conductors or equipment that convey or utilize electrical current without having a valid electrical contractor license (RCW/WAC19.28.041)
Link to Washington State L&I’s ‘Verify a Contractor’ website where the violations can be viewed: https://secure.lni.wa.gov/verify/Detail.aspx?UBI=602997629&LIC=MASTEBC903JE&SAW=
My experience with this company was horrible and I would never hire Master Builders Const NW LLC for another project again.
