Swimming Pool & Spa Inspector

Why Experience Matters!

Showalter Property Consultants has a unique and detailed method for inspecting in-ground swimming pools, featuring the skills of Jack Gallagher. Jack has spent many years in the swimming pool construction and service industry. He has construction experience in both gunite and shotcrete structures and vinyl liner pool construction. Jack has inspected hundreds of swimming pools, including concrete, vinyl, and fiberglass.

Years of service experience allow Jack to comfort both experienced and first-time pool buyers. His comprehensive swimming pool inspection reports, including underwater color video of the complete pool shell, are well-regarded in the market from Potomac to Ocean City and Lutherville to Southern Maryland. Customer attention and clear communication are his focus.

The findings are presented in a manner so you can quickly obtain quotes for repairs by local pool service companies, and Jack is always available by phone to help you with any questions, sometimes while he is enjoying his own pool!
Leak Detection

Leak Detection

Jack uses state-of-the-art equipment for leak detection, bringing his experience and expertise to every job. The inspection can locate leaks in swimming pools, irrigation systems, radiant heating systems, and underground systems.
Mold Sampling

Mold Sampling

Jack has completed InterNACHI’s Mold Inspector Training and ADVANCED Mold Inspector Training courses. Having assisted in many mold investigations, Jack is fluent in all sampling areas, including air, swab, tape lift, and VOC sampling. Every report includes detailed documentation to inform the client of specific test results. A follow-up phone call is always made to ensure the client knows precisely what was found, possible health effects, and recommended next steps.
Radon Testing/Air Quality

Radon Testing/Air Quality

Jack has performed hundreds of radon tests in the Annapolis/Baltimore/Eastern Shore. Using the most comprehensive testing equipment available, our tests give you MUCH more than just a number. Each report includes at least 48 data points to enable you to see trends instead of a raw number. While usually associated with a real estate transaction, we have performed many tests for people who want to know the air quality they breathe in their homes.
Water Sampling
