What we do
From the first stake in the ground to the last winterization, we handle every part of your sprinkler system so you don't have to think about it.
Custom-designed sprinkler systems for any yard size. Trenched, plumbed, and programmed — typically completed in 1–2 days.
Broken heads, leaking valves, dead zones, controller issues. We diagnose the real problem and fix it — no guesswork or upselling.
Get your system back online safely after winter. We pressurize, test every zone, replace what's broken, and program your schedule.
Protect your investment. We blow every line clear with commercial compressors before the first hard freeze — no cracked pipes in spring.
Wi-Fi enabled controllers that water your lawn from your phone and adjust to local weather automatically. Save water, save money.
Annual backflow preventer testing required by Virginia code. We test, certify, and submit paperwork to your water authority.
Our story
Montes Irrigation LLC is a family-owned irrigation company based right here in Manassas, Virginia. We started with one truck, one shovel, and a simple promise: do honest work for honest people, and the rest takes care of itself.
Over 20 years later, that's still how we operate. No high-pressure sales. No subcontracted crews. When you call, you get the owner. When we install your system, we install it the way we'd install it at our own house.
We work with Rain Bird because they're the gold standard — the same components used on golf courses and commercial properties. You're not getting box-store parts that fail in two seasons. You're getting equipment built to last 20+ years.
“If it's not done right, it doesn't leave your yard. That's the rule.”
How it works
A clear, no-surprise process from the first phone call to the day your system runs itself.
We come to your property, walk the yard with you, and give you a clear written quote — usually within a day or two.
We map out zones based on your yard's layout, sun exposure, and water pressure. No cookie-cutter setups.
Most installs take 1–2 days. We protect your lawn, trench carefully, and clean up like we were never there.
We program your controller, walk you through every zone, and answer every question. You're set for the season.
