Illinois Plumbing & Mechanical Company

Illinois Plumbing & Mechanical Company has served Grayslake and Lake County homeowners for decades, building a reputation as the neighborhood plumber families return to year after year. With a near-perfect 4.9-star rating drawn from ten verified client reviews, this locally-rooted business combines old-school reliability with modern diagnostic know-how. Whether handling a routine kitchen drain adjustment or responding to a gas leak emergency, the team operates Monday through Friday from 7 AM to 3 PM, ensuring daytime plumbing needs across residential properties are addressed promptly and professionally.

What distinguishes this contractor is their commitment to comprehensive backflow prevention services, an essential safeguard for businesses and municipal properties across the region. The company maintains separate expertise for residential callers and commercial or municipal clients, allowing each project to receive focused attention from specialists who understand the distinct requirements of each sector. This dual-track approach means homeowners receive personalized care while commercial property managers benefit from a team accustomed to navigating larger-scale compliance and safety standards.

Customer reviews consistently spotlight technician Elliot, who has resolved problems that stumped other contractors. One Grayslake homeowner describes how Elliot traced a gas leak multiple companies failed to locate, arriving prepared with the right equipment and completing permanent repairs at a fair price. Another client notes Elliot lowered a kitchen drain to fit a new garbage disposal, supplied the unit himself, and took the additional step of insulating exterior walls to prevent frozen pipes. When a broken water heater demanded emergency replacement, Elliot installed a new 40-gallon unit within two hours, transforming a crisis into a solved problem.
