Irrigation System Installation in Hawaii

Q: A landscaper removed a tree from my yard and accidentally damaged my irrigation system. Who pays?

The landscaper — damaging your existing systems during their work is their liability. Document the damage immediately with photos and get a repair quote from an irrigation company. Present the bill to the landscaper. Their general liability insurance should cover it. This is why you verify insurance before anyone starts work.

Q: My sod was installed and half of it died within 2 weeks. Is this my fault for not watering enough?

Possibly — sod requires very frequent watering (2–3x daily) for the first 2–4 weeks. But a good landscaper should give you a specific watering schedule in writing and install sod that was freshly cut (within 24 hours). If they used old or stressed sod, or didn't communicate watering requirements, that's on them. Document the dead areas and have a conversation before the ground gets hard.

Q: I'm getting quotes from $3,000 to $18,000 for a basic backyard cleanup and landscaping project. How do I compare?

Break down each quote into: design/planning, plant materials (ask for specific plant list with sizes), soil amendment, labor, irrigation work, and any grading or drainage included. Very low quotes often skip soil prep or use small plant sizes that take years to fill in. Verify if the contractor has a landscape contractor license (required in most states for contracts over a certain dollar amount).

Q: My new plants all died after 6 months. Does the landscaper have any responsibility?

Most landscape contractors offer a 90-day plant warranty — some offer up to 1 year. Check your contract. Beyond the warranty period, plant death from disease or owner care issues is typically not covered. However, plants that die within the warranty period from root disease or installation problems (planted too deep, wrong drainage) should be replaced at no charge.

Q: Do I need permits for a large landscaping project?

Likely yes for retaining walls over 2–4 feet, significant grading changes, irrigation systems (in some municipalities), and work near property lines. Unpermitted retaining walls can be ordered to be removed by your city. Ask your landscaper to pull any required permits — if they're reluctant, that's a red flag.

Common questions

Frequently asked questions in HI

I paid a landscaper to fix my drainage problem and my yard is still flooding. What now?

Drainage solutions require proper grading calculations and sometimes French drain engineering. If the problem persists after a repair, request a written explanation of why their solution failed and what they'll do to correct it. A reputable landscaper should stand behind drainage work — it either solves the problem or it doesn't.
