Our Story

St. Croix Pools has been in business since 2009. We design, build and oversee the production of custom pools designed to fit your needs and wants while staying within your budget.

Here at St. Croix Pools, we are active both in the office and out on the job.  Using our subcontractors, we ensure the production of your pool goes smoothly and efficiently. Working out in the field with our in-house employees allows us to have a higher degree of quality control on your pool project, as well as proper control of materials, communication and scheduling.

St. Croix Pools is here to help you, and teach you, how to properly and economically run your pool. We guarantee that doing it right the first time will save you money, extend the life of your pool and equipment, and make your experience that much more enjoyable!

We view communication with our clients as absolutely essential to both their satisfaction and the quality of the final project. We keep clients informed of all new developments. We also maintain open lines of communication so that you can tell us about any changes you’d like to make as the project goes on.

St. Croix Pools offers 2 months of free pool cleaning services with the production of your pool project.

At St. Croix Pools, we value quality over quantity. Our goal isn’t to pump out as many cookie cutter pools as possible. Instead, we stick to a reasonable amount of projects that we focus intensely on. This allows us to create beautiful, original designs for each pool and backyard. It also allows us to provide on-the-spot, personalized customer service to each and every client. Whether you need pool construction, maintenance or any other pool service for your Houston area home, we are ready to help.
