The 10 Best Irrigation Companies in Portland (2026)
Portland’s gardens and lawns see a long wet season and drier stretches in summer, so irrigation and sprinkler care matter whether you have a small yard or a commercial landscape. This list, updated for 2026, is built from Google review data using a Bayesian-style score that weights average ratings by review counts, which helps favor businesses with both high marks and sustained customer feedback. We limited the pool to companies that appear in Google under irrigation, sprinkler, landscape and related service categories, and present these results as a practical starting point for finding local providers.
This ranking is computed from Google reviews (our method). Listings marked Partner are paid advertising spots: they sit alongside the ranking without changing its order.

Frequently asked questions
How should I choose an irrigation company?
Look for a combination of strong reviews, relevant Google category listings, and transparent written estimates. Check whether the company has experience with systems like yours, ask about warranties and permits, and compare references or recent customer feedback before deciding.
What should I check before hiring someone to install or repair my irrigation system?
Confirm the contractor’s licensing and insurance status, request a detailed written estimate, and ask what parts and labor are covered. Also verify whether they handle permits, backflow testing, and seasonal services such as start-up and winterization if those matter to you.
How much does irrigation work typically cost?
Costs vary widely depending on system size, the type of components, site conditions, and labor needs. Get multiple itemized quotes and compare the scope of work rather than choosing solely on price.
