"We hired McCormick Home Builders to remodel our living room, and we are beyond pleased with the result. The team was professional, worked efficiently, and Aris design ideas made a huge difference. The room feels so much brighter and more spacious. This was the best decision we made for our home, and we were already planning our next remodel with them."

"Overall we had a really good experience with McQueen Construction. Scott was very professional and he managed the project really well. It was a very tight budget and even tighter timeline for the build and they completed everything in record time within our budget, which was incredible. Really nice family owned and operated business I would recommend to anyone in the local area. Cheers!"

"Alex did an absolutely wonderful job on the remodel of our home. We thought it would take a lot longer than it did! He is very honest, transparent and explained everything very well before starting so we were well-informed of what to expect. He took take of our home and the space he worked at diligently. We worked with various contractors in the past and he will be our go-to going forward! That says it all!"

"Fantastic work! Speedy work done with precision. Took time to be as careful as possible maneuvering a tractor around my yard without damaging anything. Would highly recommend."

"Very honest engineer. He performed a mandatory seismic inspection that was required for the city of Hayward. There was no foundation issue whatsoever. Before Mr Padir did the inspection I had a retrofit company look at my building and they told me it would cost $58k to fix the problem and I almost fell for it. It turns out that one joist was rotten from a sewer leak that was repaired. It is hard to find honest people these days. I am so glad it is only a cosmetic fix and a sister joist installed next to it to relieve the pressure on the building. Thank you once again Mr. Padir. Excellent job and quick turnaround."
