POOL-ology runs a Georgetown page of its own, and the two companies answer a Georgetown homeowner's question in different ways: one is a full-service pool company that builds and then maintains, the other is a two-person gunite builder that designs, builds and renovates. Both are reasonable answers. Which one fits depends on what you want after the water goes in.
Everything in the POOL-ology column comes from their own website, read on October 28, 2026, and every Trinity row comes from Trinity's own pages on the same day. Nothing here is drawn from a review or a directory listing.

|---|---|---|
| Brand spelling on their own site | Written "Pool-ology" in the Georgetown page headings and "POOL-ology" in the site's own captions and page titles | Written "Trinity Pool Construction" throughout; the footer reads Trinity Pool Construction LLC |
| How the company describes itself | "Georgetown's full-service pool company. We design and build it, renovate it, and service it, for the life of your pool." | "Custom pools, built slow, the way they should be. Family-owned by Donna and Ben. Pools since 1987, built by the same two people start to finish." |

Where Trinity is the better call
- You want gunite, not a choice of shells. Every Trinity pool is sprayed on site, which is what lets the shape follow the yard instead of the yard taking a shape. There is no model range to pick from.
- Georgetown has its own rules and Trinity works them. The Georgetown page covers Sun City and HOA drawings prepared to pass review the first time, limestone and San Gabriel terrace soils read before the excavation is planned, and the City of Georgetown permit and stamped engineering pulled by Trinity.
- The owners are the whole company. Donna and Ben have kept the business the same size on purpose, and would rather do six pools right than twelve fast.
If what you want is one company on a weekly schedule for the next decade, that is a real difference and the table says which one lists it. If what you want is a one-off gunite pool drawn for your yard by the people who will build it, that is this side of the table.
Questions people ask
Does Trinity build fiberglass pools?
No. Every pool Trinity builds is gunite, sprayed on site over steel, which is what allows a true one-off shape. POOL-ology lists both fiberglass and gunite construction on its Georgetown page.
Who pulls the City of Georgetown permit?
Trinity does. The Georgetown page states that Trinity pulls the building permit, arranges the stamped engineering, handles the electrical and coordinates inspections end to end.
Where do the POOL-ology facts on this page come from?
Their own website, read on October 28, 2026. Their column is sourced to pool-ology.com and its Georgetown location page, and the fact sheet behind this page records the URL and the date for each row.
