If you are expecting a written report, forget it. William just comes out and says you have issues. Then he proceeds to verbally tell you what the issues are using words you have never heard before. I would not recommend using this person and I will never contact him again.

William went above and beyond what was expected of him for the structural inspection. I have had structural inspections for properties all over the country and his was the most thorough report I have ever received. I cannot recommend him highly enough.

We needed a structural engineer to tell us if a wall we wanted to remove was load bearing. William came out right away, showed up on time and charge a very modest fee. I would highly recommend using him, if you need a structural engineer. 6 out of 5 stars.

William provided me with a Architectural and Structrual set of plans for a kitchen expansion. He was very knowledgable, professional and fast. I would recommend him to anybody that needed this type of work done.

William was a life saver. We needed plans done quickly to restart a home remodel that had been shut down because of permit issues. William came out within a few days, was incredibly knowledgable, worked on our project over a holiday weekend and delivered a professional set of plans for a very reasonable rate. I know it's sometimes weird finding people on the internet but I have nothing but positive things to say about William!

Overall I was very impressed with the value for money, my only reservation was that nothing written was provided post inspection. Then again at half the price of the home inspector and only 33% more than the pool inspector I can't complain too muc, he saved me from buying a home I couldn't afford to repair.

Mr. McCarthy called me immediately and had lengthy discussion about the project and set up an appointment to come out & evaluate the scope of work. He is extremely professional & knowledgeable. He offer many options and was quite pragmatic about things that would accomplish what we need without going overboard on costs. Unfortunately, the scope of work is going to be more expensive than we had anticipated so we are going to put the add-on off for a while. I will hire William when we are ready to proceed.

Mr. McCarthy was very informative, proffesional, and helpful to us with making an informed decision on whether we should risk buying an as is, HUD home. The home needs alot of work, and didn't come with many disclosures. We had to get many inspections and estimates, so we would know what we were getting ourselves into. The foundation and structural information was invaluble, since this is basic to the integrity of the home. I would reccomend Mr. McCarthy to anyone who is contemplating buying a home, since it is an expensive venture and should be a well informed one.

Performed task well. I had an architect draw conceptions and Mr. McCarthy do the plans. Wish alternative ways of construction were explained by one or the other. After getting bids from the first set of plans, I had to have them redrawn so the structure did not need expensive retaining walls. It would be helpful if professionals would give advice or warn of potential expensive methods and offer alternatives.
