Stanley Louis reviews
• last updated FEB 26, 2026Loading map...
The Verdict
Stanley Louis has a track record on boiler and plumbing work, but their solar service raises red flags. One homeowner called six times for a no-hot-water problem, and the company kept leaving after declaring it fixed, only for the issue to return days later. Another paid for a solar water heater diagnosis, was promised a return visit with the replacement part, then never saw the technician again (though accounting called the next day to collect). We found a pattern of unresolved solar issues and disputed billing. Four reviews describe recurring problems or broken follow-up promises, and one customer paid over $4,000 only to learn labor coverage ends at 30 days. On the boiler side, eight reviewers call Stanley Louis their go-to for hydronic heating, and one property manager has relied on them for 15 years after they fixed a rooftop broiler for $450 instead of the quoted $20,000 replacement. If you need a Raypak boiler repaired, their technicians know the systems cold. If you're considering them for solar water heating, the record suggests you'll be chasing them for callbacks.
If you're hiring Stanley Louis for traditional boiler or plumbing work, their long-term customers vouch for their expertise. But if your project involves solar water heating, expect unresolved issues and a 30-day labor warranty that won't cover the follow-up visits you're likely to need.
Reviews That Shaped Our Verdict
Sharonrivka paid for more than $4,000 worth of work at the end of August on her home’s system. When she called today to request a follow-up technician because problems persisted, she discovered the company only backs labor for 30 days. Frustrated, she warned others to "beware of this community." The clearest takeaway: after a costly late‑August job, the only firm protection she received was a 30‑day labor warranty.
Vykeenb brought the company out to their condo complex six times to deal with a recurring lack of hot water. Each visit ended with technicians leaving claiming the issue was fixed, but within a few days the hot water would fail again. After the sixth short-lived repair, the HOA started actively pursuing replacement of the system. The lasting impression: repeated temporary fixes rather than a durable solution, which pushed the association toward replacing the equipment.
Peter Huh called the company when his home's solar water heater stopped working; a technician showed up to inspect. He was told the tech would return with a replacement part, but the tech never came back. Instead, the very next day the company's accounting department phoned to collect payment for the visit. He ended up with no repair and a bill demand for time spent on an unfinished job — the standout problem being that the company tried to collect despite not following through on the fix.

What You Can Expect
Shawn met Stanley Louis nearly 15 years ago while managing a 40-unit complex, and recently ran into a major hot-water failure: a roof-mounted boiler had gone bad. A regular plumber pushed for a full replacement that would have cost nearly $20,000, but Stanley Louis stepped in, found a repair solution, and completed parts and labor for $450. The fix restored hot water across the building immediately and avoided the hefty replacement. With 25 years in property management, he judged the company’s performance against a long experience — they proved they’re at least as dependable as they were a decade and a half ago, if not more so. The lasting image Shawn remembers is simple and concrete: a working boiler and a $450 bill where someone else wanted almost $20,000.
Jenny Y. had a small, 10-minute boiler repair in an HOA building where several plumbers are approved. She called and spoke to Patrick, the manager, to confirm that a single hourly service call would cover shutting off the building water, letting her contractor do the quick repair, and turning the water back on; Patrick confirmed it was doable if the plumber knew the system. They booked the company, but ended up billed for two hours because the crew took nearly two hours to turn the building water off and on — in the very building they installed and visit regularly. An update from Jenny clarified that handing the tech the key to unlock the valve only took five minutes, so that wasn’t the cause of the delay. The memorable detail: despite a pre-booking assurance, the job ran long and was billed as two hours, so anyone scheduling a short shutoff with this crew should get an explicit, written one-hour cap if they want to avoid surprise charges.
Erick discovered water leaking from his water heater and reached out to SLC for help. He found their communication prompt and the service efficient; Scott showed up, diagnosed the problem quickly, and handled the replacement with clear expertise. This was Erick’s second time working with the company, and he walked away tremendously pleased again. The detail that stood out was the combination of speedy, transparent communication and Scott’s confident, proficient work—turning an urgent leak into a straightforward fix that reinforced why he returned to them.
