## The honest read

Maxum Irrigation & Plumbing opens, fixes, installs and closes down in-ground sprinkler systems, and on Google it holds 4.9 stars from 232 ratings. The company says it has been in business 20 years.

A recent customer said the owner was on-site working alongside his crew for most of an irrigation install, and that the job was finished ahead of schedule. A customer who had moved into a house with a 12-zone system that wasn't working said Lance and Jay got it up and running. One customer who could not get into an irrigation system for over a year said Tim started it up, figured out the password and checked the heads and zones, and Jay and Kevin K then disconnected a faulty controller connection. Russell and Jason adjusted heads so a recent customer's new gardens are covered, and replaced a head. Lance winterized a recent customer's irrigation system quickly. A recent customer said the company manages both their irrigation system and their lawn care, and a recent customer said they had used it for six years for lawn irrigation and plumbing.

A 2025 customer said Bob reconfigured several sprinkler heads to make room for a new patio and walkway on a yard with slopes and rocky ground. A 2024 customer said the heads stopped popping up three weeks after the seasonal turn-on; that customer said Jason D. found a clogged filter and fixed it, and that Maxum did not charge for the visit. A 2022 customer said the crew installed 16 zones of in-ground irrigation over 2.5 days.

A recent customer said concerns about service and billing were never resolved and that emails asking for an answer went unanswered. A recent customer called the company unreliable and said it never answers phones or emails. A recent customer asked about a credit and a head replacement and heard nothing back from July 2 to August 31; that customer later wrote that Nicole called after the review and the issue was believed resolved. In a 2023 review, a customer with a system in Mystic said a new line to water stoop pots was billed $702.45, did not work, and a second visit to correct it brought a $264.01 bill.

Connecticut lists its home improvement contractor registration, HIC.0640606, held by Maxum Irrigation, LLC, as expired.

**Strengths:**
- Owner on the job — a recent customer said he worked alongside his crew
- A 16-zone install — a 2022 customer said it took 2.5 days
- A free repair visit — a 2024 customer was not charged for a clogged filter fix

**Concerns:**
- Unanswered emails — a recent customer said billing concerns were never resolved
- A slow callback — a recent customer heard nothing from July 2 to August 31
- A billing dispute — a 2023 customer was billed twice for a watering line
