Just moved into a house with an older but very nice concrete pool. I am not real satisfied with knowledge or quality of work from local companies. Had to use them this year because of such little time. But I plan to become self sufficient next year, and will thank everyone in advance for taking the time to look over my future and current (just placed one on closing) questions and provide input when able. I have already gained a tremondous amount of knowledge from this site, and hope to be able to give back as my experience and expertise grows.
