Welcome to the area.
I don't know what kind of pool company you need, repair or maintenance, but for the former I highly recommend Pool Works. They are a family-owned company, highly professional, very patient with nosey/picky customers like me. This past summer they resurfaced the pool, installed a doubledrain, installed a buffer between the patio and the pool and painted the pool deck. It was all done within 5 days, having started one week after we signed the contract and it was all done as promised. The sons of the owner came out several times, both on their own and when I requested their input. The workers who came were courteous and cleaned up after themselves. Really great company. They were recommended to me by a friend who is also nosey and picky. Their telephone number is ###-###-####.
For appliance repair I really like the guys at 1960 Appliance Service. Another small, family-owned company, they usually come out to make repairs the same day I call. Wow. What really impressed me is their honesty. i.e. When our 3-year-old front loader washing machine developed a slow leak in the drum, the repairman gave us two options. A - we could pay him $300 to replace the little plastic piece that may or may not need to be replaced again in three more years. B - we could go to Home Depot and buy a plastic water-heater tray for $35 to put under the washer. It's been 4 years and the machine is still working well with a slow leak sitting on the $35 tray. Their telephone number is ###-###-#### and they do service The Woodlands. They have a BBB rating too and take checks or credit cards.
Good luck.
