Norm's Plumbing, Heating and Supply, INC

Norm's Plumbing, Heating and Supply, INC has earned a 4.7-star rating across 29 verified reviews, positioning the company among Boulder's most recommended plumbers. The family-operated business serves residential clients throughout Boulder proper and unincorporated Boulder County, an area many competitors overlook despite advertising local coverage. Technicians Ernie, Doug, and Samantha have handled plumbing and heating needs for multiple generations of the same households, according to one reviewer who described the team as exceptionally honest and dedicated. The company maintains weekday service hours from 8 AM to 4 PM, with reduced hours on Friday, and has built its reputation on responding to customer concerns whenever they arise.

Reviewers consistently praise Norm's for practices that contradict the industry's less trustworthy actors. One customer contrasted their experience with another company that quoted a higher price and then failed to follow through, while Norm's arrived after hours to address an urgent water heater leak within 24 hours and came in 20 percent under the competing estimate. The team reportedly informs homeowners about code requirements that others overlook, such as expansion valve needs for high-efficiency water heaters, without using these discoveries to inflate final costs. Cleanup after completed work receives repeated mention, with reviewers noting spaces were left exactly as they found them.

Customer stories from the review record highlight specific scenarios where Norm's differentiated itself through action rather than promises. Ernie completed a high-efficiency water heater installation after discovering an overlooked expansion valve requirement, retrieving the part and finishing the job faster than the homeowner expected. For another customer facing a Friday boiler failure, technicians Ernie and Samantha responded with what one reviewer described as expert knowledge combined with empathy for the homeowner's situation. A reviewer in unincorporated county noted the team performed emergency after-hours work that required traveling to an area other companies refused to service.
