Pool service in Northwest Hills
Northwest Hills has the heaviest concentration of pools we service, and most of them are no longer young. Sullivan’s covers Northwest Hills — Highland Park West, Bright Leaf and the streets off Balcones Drive. If your pool went in with the house, its pump, heater and plaster are all somewhere in the second half of their lives, and the useful thing we can do is tell you which one is closest to the end before it decides for you.

The ground under Northwest Hills
Johnson Creek and Taylor Slough cut down off Mount Bonnell through these streets, so the lots run in steps rather than flats.

What we see in Northwest Hills
The pools here are old enough that equipment failure, not water chemistry, is what most calls are about.
The ground under Northwest Hills
Thin soil over rock, steep lots, and a canopy of live oak and Ashe juniper. Decks stay put, but the leaf and pollen load is heavy from December through April and skimmer baskets fill fast.

Northwest Hills — questions people ask
Do you service pools in Northwest Hills, Austin?
Yes. Northwest Hills is one of the areas Sullivan’s Pool Service covers, and our routes already run through it — Northwest Hills, Highland Park West, Bright Leaf and the streets around them, on a weekly schedule. Because your pool sits on a fixed route with a technician assigned to it, we can usually come back the same week when something breaks.
What should I expect from a pool in Northwest Hills?
The pools here are old enough that equipment failure, not water chemistry, is what most calls are about. Age is the single best predictor of what any pool needs: under about ten years it is mostly chemistry and cleaning, and past fifteen the pump, heater, salt cell and plaster all start coming due one after another. Knowing which of those is closest is most of what a good weekly service gives you.
What ground is Northwest Hills built on, and why does it matter for a pool?
Edwards limestone, west of the Balcones Escarpment. Thin soil over rock, steep lots, and a canopy of live oak and Ashe juniper. Decks stay put, but the leaf and pollen load is heavy from December through April and skimmer baskets fill fast.
