We absolutely love our pool done by Ultimate Pools by Fetter! Ross is by far the most knowledgeable pool contractor out there and we had quotes from 6 different contractors. Ross went above and beyond researching laws to allow us to change our backyard, that other contractors wanted myself to do. He is definitely a step a head of the game at all times. I highly recommend this company to any one thinking about building a pool. Ross was with us a 100% of the way and a phone call away at all times if needed. We will have a lifetime of memories in our backyard due to what Ross created for us.

Four years in and this pool still delivers on every promise made at the start. From the first consultation through swim day, the process was smooth and the crew was great to work with. They built exactly what we envisioned — the right shape, the right features, and a bubbler the kids love. When our pool light went out years later, they replaced it at no charge with a smile. Best decision we ever made.

My wife and I are very happy we went with Ultimate pools by Fetter for our pool. We talked to a couple of other companies and were impressed by Fetter because they didn’t try to talk us into anything we didn’t want. They were patient with us during our design phase as we started out wanting a spa and water feature and then changing our minds to just getting a pool. At no time did they try to talk us into into getting a particular pebble finish or plaster finish for the interior. Ross was straight forward about what he thought would work best for us and told us the pros and cons for every decision we made. He was great at explaining the process and what to expect each step of the way. Once the pool was complete, they have been great at answering all of our questions about pool chemistry too! We would definitely recommend using them to put in your pool! We went with a French Gray plaster and love the way the water color turned out.

Frequently Asked Questions
Does my HOA need to approve the pool design before I apply for a permit? +
Yes. Mountain House HOAs require architectural review and approval before pool construction can begin, and this review typically needs to be completed before or alongside county permit submission. Fetter prepares the submittal documentation — site plan, design drawings, equipment placement, fencing details — structured to address the specific items Mountain House HOAs evaluate.
How does expansive clay affect pool design in Mountain House? +
Mountain House’s expansive clay is active to significant depth, meaning the soil around the pool shell moves seasonally whether or not it’s visible at the surface. The pool design accounts for this through heavier steel reinforcement, drainage provisions that manage moisture levels around the shell, and careful structural connections between the shell and attached features like raised spas or deck walls. All of this is incorporated before construction, not discovered during it.
Why does Fetter recommend pebble or quartz finishes in Mountain House? +
Mountain House’s water supply from the Byron-Bethany Irrigation District is notably hard — high in minerals that accelerate the degradation of traditional plaster pool interiors. Pebble aggregate and quartz aggregate finishes are significantly more durable in hard water conditions, hold their appearance longer, and require less corrective chemistry to maintain proper water balance. For Mountain House pools, the upgrade in finish pays for itself in reduced long-term maintenance.
Does hard pan on the east side of Mountain House affect design? +
Yes. Hard pan in east-side neighborhoods affects excavation planning and drainage design. Excavation through hard pan requires the right equipment and technique, and drainage provisions must account for how water moves (or doesn’t move) in and around a cemented layer. Fetter identifies hard pan during the site assessment and adjusts the design and construction approach accordingly.
Can Fetter design a pool that meets both HOA and county standards? +
Yes — and this is exactly where experience matters. Mountain House HOAs may impose design constraints — fencing style, equipment screening, setback distances — that go beyond county minimums. Fetter designs to satisfy both sets of requirements from the start rather than designing for county code and then reworking for the HOA. One design process, one set of revisions, one path to approval.
