- How long does installation take?
- Highly variable. One 32k gallon system was installed quickly once the tank arrived; gutters took one month to schedule; underground pipes took 10-12 weeks. Many customers report long waits between deposit and start date (4+ months in two cases).
- Do they handle the full project or do I need other contractors?
- IWS coordinates tree clearing, electrical, plumbing, and gutter work in-house, so you usually do not need multiple companies for a complete drainage or rainwater system.
- Will they return if something goes wrong?
- Five recent customers report ignored warranty requests via email and phone over weeks to months; older customers report 24-hour responses. Current responsiveness to post-project issues is unreliable.
