After many years as a licensed contractor doing remodel and refurbishing for my own company, I have decided to move to inspections so I can help homeowners to be aware of issues with their houses and for home buyers to be fully aware of any issues they may have missed in the homes they plan to buy. I take great pride in my professionalism, timeliness, and superior customer service on every job. I make sure to develop a lasting relationship, so that the next time service is needed, there will be no question on who to call.

"Jeff was responsive, easy to work with, and took the time to understand what my concerns were with the property we were considering."

"These guys were great. Professional and super responsive. I worked with them for a duplex in Gresham over the summer. They treated mold issues in the attic and the garage, performed duct work to fix the root cause of the problem, and also replaced sheet rock. I would strongly recommend this team. The owner was very understanding and was able to work with me to meet our aggressive timelines for closing the real estate transaction."

"Ambrosio was friendly and kind, made a thorough search through the attic and rooms of the house to evaluate the roof leak and resulting mold, and gave a detailed estimate of all the work that would be involved in remediation.
