We loved working with Sam and having him build this wheelchair ramp! He came in under other bids in time frame and cost. Great communicating when he would be on site and when different materials would be available. Respectful of our home and cleaned up really well at the end of the job. Sherman contracting is our new go-to for any contracting job.

Sam came and took a gigantic cottonwood tree down for me at my front driveway. His services were prompt, quality, and affordable. Would recommend to 10/10. Thanks again Sherman General Contracting 🍻

Sherman General Contraction did some significant work on our home. They did a fantastic job and I would highly recommend them. Their lead carpenter was a very skilled craftsman at the highest level.

Look no further. Sam is your guy! We just had a full bathroom remodel done and have nothing but great things to say about Sam and his crew. My husband and I have had one bad contractor experience after another for the last 4 years and Sam restored our faith in the industry. All of them are kind, respectful and skilled at what they do. They did absolutely beautiful work; they paid attention to all of the small details and noticed everything before we did so we didn’t have to point out any touch ups. We had a large amount of tile work and it was executed flawlessly. They finished on time and slightly below the estimate. We couldn’t be happier.
