Posted on Carol TikkanenTrustindex verifies that the original source of the review is Google. I have had James Alexander to my home on several occasions for plumbing issues. James Alexander replaced a garbage disposal, he installed a new faucet, and he fixed a leaking shut off valve under my sink. He was very professional. His responsiveness and communication was excellent. He was on time, and he left the work areas very clean when he was finished. I would definitely call on James again, and I highly recommend him for your plumbing needs.Posted on Desirae EchevarriaTrustindex verifies that the original source of the review is Google.

Melr Alexander was on time for an estimate gave me real insight and some fair pricing. Other local big name plumbing companys seemed pushy.

I would call this service in the future.Posted on Denise ScagliariniTrustindex verifies that the original source of the review is Google. Excellent work, finished in a very timely manner! Couldn’t be happier with Alexander plumbing and will definitely be using them again!Posted on Jenn LykeTrustindex verifies that the original source of the review is Google. We had Kuper in our home today. He should be commended for his professionalism and top notch communication skills. He took the time to explain his findings along the way instilling confidence and trust. He even put up with our kitten licking his face as he was at our table finalizing the invoice. Seems to be an all around good guy. I appreciate our friends at JD sewer for recommending Alexander Plumbing to us.Posted on Donna BellTrustindex verifies that the original source of the review is Google. Alexander Plumbing (Cooper) did a great job for us. They fixed the problem and did it all promptly and correctly. I’m not sure what else they could’ve done to provide customer service.
