Why the Mountain House flock is persistent
This town sits between open agricultural ground and a new low-rise housing stock, which is close to ideal feral pigeon geography: feed on one side, unlimited fresh ledges on the other.
Feed comes off the fields west and north toward Byron and Grant Line. Water is not a limit either, between irrigation and the residential landscape.
The housing stock supplies the rest. Rail-mounted arrays over flat tile, patio covers, and articulated elevations with recesses give a flock more sheltered ledge per block than an older neighborhood with simpler rooflines.
That is the honest framing for control here: you are not going to reduce the local population, so the objective is to make your specific building not worth the trip.

The three things that actually change pigeon behavior on a property
Remove the roost, remove the accumulated scent and staining that marks the site as established, and remove the incidental food and standing water.
Closing the ledge is the main move and it is permanent. Everything else supports it.
Cleaning matters more than people expect. An established site carries dropping accumulation and residue that reads as a proven roost, so leaving it in place keeps the flock investigating even after the ledge is meshed.
The third piece is on you, and we will say it plainly: uncovered feed, spilled birdseed, open compost and standing water on the patio all keep the flock local. Proofing works regardless, but the flock stops circling faster without them.

What we do not do, and why
No poisons, no lethal trapping, and no products that rely on the bird's discomfort — all three either fail, create new problems, or both.
Poison on a residential roof is a bad idea on every axis, including where the bird then dies and what eats it. It also does nothing about the ledge, so the vacancy is filled.
Trapping has the same structural flaw. Remove individuals from an attractive site and the site is simply re-colonized, which turns control into a subscription.
Discomfort products — spikes, gel, tape, sonics — get habituated to. We have removed enough spike strips with nests behind them in the Central Valley to be blunt about it.

What a control visit costs in 95391
Most residential pigeon control here is a cleanup line from $200, plus array mesh at $58 per module and any ledge closures quoted on site, with a $297 standalone minimum.
An array-only problem is fully predictable: count modules, multiply by 58, add cleanup. A 16-module array with a moderate colony lands around $1,128.
Whole-home work with patio pockets and eave tile ends needs the walk, and that is where the site-quoted closures come in.
Adding the stucco soft wash at $0.36 per square foot is usually worth it on the same visit, because dropping streaks on a village elevation are the part your neighbors and your HOA actually notice.
