Millennium Custom Pools

Millennium Custom Pools operates as a family-owned swimming pool contractor out of Montgomery, Texas, with Mario handling the day-to-day side of the business. The company lists more than 20 years building custom pools across the greater Houston area that includes Spring, Cypress, Tomball, The Woodlands, Missouri City, Sugar Land, Pearland and nearby towns. Services cover new pool construction, pool renovations, outdoor fireplaces, outdoor kitchens and custom patio covers, plus swimming pool repair work. The address on file sits at 5145 Castlebrook St in Spring.

Reviewers describe new pool builds that wrap up in six weeks and re-plaster jobs that keep downtime to about four days. Deck and tile replacements get mentioned for changing the look of older pool areas, while some customers note resurfacing work completed years earlier still holding up. On the other side, reports include pumps sized too small for the contract, missing salt systems and robot cleaners, spa heating failures, and overflow drains placed in the wrong spot that flooded side areas. One job left trash on site for weeks until repeated calls prompted pickup.

The company keeps customers informed during construction and walks through the steps before work begins. Jobs start and finish when promised in several accounts, with the crew adjusting plans to fit different budgets after quotes from other outfits. Service reaches the listed Houston suburbs, and reviewers note clear explanations on timelines and scope. Some projects ran into extra payment requests for items like fire bowls and controller programming that stayed unfinished, along with owner disputes over contract details.

Google shows a 4.3 rating even with low review counts listed. Common points across feedback include solid results on resurfacing and full builds paired with complaints about incomplete equipment installs and cleanup follow-through. Positive notes highlight quality on tile and deck additions, while negative ones focus on organization and contract execution.

“2 star for finished the pool. Be careful with the owner Mario, he blamed everything from the sale person. Left trashes for weeks before collecting, we had to keep reminding them to clean up. Still haven’t installed the wifi for the controller. Mario asked for more money to install the fire bowls. Didn’t give us the robot cleaner as in the contract, Mario blamed the sale person for messing up the contract. Be careful with him, we recommend using different companies if people want to build new pool.”

“I agree with the previous reviewer’s comment (“horrible company to deal with”). I had a nightmare experience myself. This company is disorganized, unprofessional, and unethical. If I could give them 0 stars, I would. • Installed a pump that was half the size of what was needed and in the contract, causing performance issues. • Spa doesn’t heat. Half the ports have no flow. Rotational jets not installed. • Pool overflow drains to side of pool (instead of street per contract and code), flooding my backyard alley • Salt water pool equipment never installed; various pumps/blowers never installed. • Pool autofill shoots out the deck, not in the pool. • Pool controller not programmed. • Chlorinator installed backwards (doesn’t add chlorine). Flange also leaks. • Filter backwash system piping left open in front flowerbed and not properly connected to sewer system. • Air temp and spa thermometers installed backwards. • Didn’t manage initial pool chemistry, provide cleaning equipment (including vacuum), or explain how equipment works or how to maintain it. • Pool sat first week without a pump or properly maintained chemicals. As a result, my plaster may be permanently compromised. • Tile wo”

“The new decking and tile that was just installed completely transformed our pool area from an ugly duckling to a beautiful swan. The job was done quickly and professionally and "on time". We used Millennium to resurface our pool a few years ago and the job was outstanding. Now we are a customer for life. Thanks for the high quality experience.”

“Super reliable, honest and comparable to competitors Millennium custom pools was on time, and explained to me all the steps of a new pool construction to me. I researched and got different quotes, but Millennium Custom Pools worked with me on what I was looking for based on my price. This company really knows what their doing and definitely goes out of their way to guarantee customer satisfaction.”

“Had a great experience re-plastering our pool! Project started and ended on time. Process was as described and we were only without a pool for about 4 days. Highly recommended. I will call them again when its time to update our patio and pool tile.”

“Such detail and quality of work! Beyond impressed! I love my new pool, thank you for your patience and helping a visioned dream come true! Summer ready!”

“Our beautiful pool was built and ready to go in 6 weeks! Mario had promised he could get it done and up and running and he certainly delivered. The pool is beautiful and complements our home so well.”

“First let me say this company is on point. Kept me updated throughout the whole process of my new pool. We love how you guys transformed our back yard and can’t wait to have a party to show it off.”

“We had our pool re-plastered and tiled and couldn't be more pleased. Excellent service and quality product. Choosing a contractor is always difficult but we are so happy we chose Millennium!”

“I really liked the renovations you guys did for my friend's pool, so I decided to use you to build my new pool. I must admit my expectations were extremely high, and you guys definitely exceeded those expectations!”
