## The honest read

A late-day water-heater failure was followed by a new installation that same night, according to an August 2026 JLS Design customer. Plumbing jobs and repeat customers feature throughout the company’s reviews, from routine projects to urgent repairs. JLS says it has 24 years in business and is insured.

Google lists a 4.8-star average from 37 ratings. Recent customers praise clean work, respectful treatment of their property and pricing. A Farmington customer writing in October 2025 said they had used JLS three times for plumbing projects and appreciated punctuality, workmanship and reasonable prices. Another customer writing in May 2024 described years of work at multiple locations.

Customers also describe heating and remodeling work. In February 2026, a reviewer said John responded promptly and repaired their furnace. An August 2024 customer credited Jon with a water heater, a full kitchen and a completed half bath. A separate August 2025 customer praised the plumber’s problem-solving and explanations, saying they learned more about their home through the visit.

Follow-up is the subject of a March 2025 complaint. That customer said the installer came to inspect a problem with something he had installed, then stopped responding to text messages.

**Strengths:**
- Water heater response — August 2026 customer reported installation the night it failed
- Returning plumbing customers — October 2025 reviewer described three completed plumbing projects
- Clear repair explanations — August 2025 customer praised problem-solving and homeowner education

**Concerns:**
- Installation follow-up — March 2025 customer reported an inspection followed by unanswered texts
