33 Years of Locally-Owned Operation Across Arapahoe and Douglas Counties
RMW Plumbing Services has operated as a locally-owned firm since 1993. The 33-year operating tenure covers two Colorado counties: Arapahoe (Aurora, Centennial, Englewood, Greenwood Village) and Douglas (Highlands Ranch, Lone Tree, Parker, Castle Rock, Larkspur). The deeply-invested community-service positioning sets apart RMW from larger franchise operators in the Denver Metro market.
Larkspur and Aurora Operating Base
RMW operates from a Larkspur base supporting the Douglas County corridor plus an Aurora working radius covering the eastern Arapahoe County market. The dual-county service structure supports the I-25 south Denver corridor plus the eastern Aurora-and-Centennial residential market. Service extends through more than 12 named Denver Metro south communities.
Colorado Plumbing Contractor Compliance
RMW Plumbing operates under Colorado Plumbing Contractor licensing through DORA State Plumbing Board. BBB Accreditation provides third-party reputation verification. Service mix covers plumbing repair, drain cleaning, water heater installation, fixture installation, and the broader plumbing-trade scope across Arapahoe and Douglas Counties.
Reference Notes
Colorado plumbing licensing runs through the Department of Regulatory Agencies (DORA) State Plumbing Board. DORA issues Master Plumber, Journeyman Plumber, and Residential Plumber credentials through sequentially numbered records. Verification runs through dora.colorado.gov. The City of Aurora Building Division issues building permits within Aurora city limits. Aurora Water handles water service connections plus annual backflow-prevention testing. Surrounding Arapahoe County, Adams County, and Douglas County jurisdictions administer their own building-permit frameworks.
Aurora-area residential housing reflects the post-1945 Denver Metro growth pattern. Pre-war housing is limited; Aurora remained a small Adams County community through the 1940s. Postwar tract construction built out central Aurora through 1945-1975 tied to Buckley Air Force Base (originally Buckley Field, established 1942) plus the Aurora-side Denver Metro residential expansion. The 1970s-1980s drove the Heather Ridge, Aurora Knolls, and central Aurora corridor expansion. The 1990s-2000s saw Saddle Rock, Tollgate, Mission Viejo, and the southeastern Aurora master-planned-community surge. Murphy Creek, Highlands at Saddle Rock, and the southeastern Aurora arc extended outer-suburban growth through the 2000s. Cold-climate freeze-protection plus expansive-clay-soil substrate plus high-altitude pressure considerations shape recurring service categories.
The four firms profiled cover four positions on the Aurora market arc. Bill Smith Plumbing & Heating leads tenure with Bill Smith’s WWII-veteran 1956 founding plus three generations of family ownership across 70 years, supported by Colorado PC.0001448 plus MP.00178988 and BBB A+ Accreditation. Allen Service follows with 64 years of three-generation family operation since 1962 plus dual Colorado licensing under PC.0000729 plus EC.0102432, with a Front Range service map covering Aurora through Fort Collins. Royalty Plumbing brings 39 years of Leon Zokovski Master Plumber operation since 1987, with CO Master Plumber License #180274 from a southeast Aurora South Jericho Court base. RMW Plumbing Services runs 33 years of locally-owned operation since 1993, covering Arapahoe and Douglas Counties from a Larkspur and Aurora dual base.
Verification paths run through dora.colorado.gov, BBB Denver-Boulder listings, the PHCC of Colorado directory, and the City of Aurora Building Division contractor records. Pre-1975 central Aurora housing tilts toward Bill Smith’s 70-year three-generation depth. Front Range plus Northern Colorado multi-trade work fits Allen Service. Owner-operator Master Plumber service in southeast Aurora fits Royalty. Dual-county Arapahoe-and-Douglas service fits RMW.
Selection Methodology
Selection follows four criteria. First, continuous family ownership or founder-operator continuity outside the national rollup pattern. Second, verifiable Colorado Master Plumber license cross-checked via the Colorado DORA State Plumbing Board public lookup. Third, BBB Accreditation or equivalent third-party rating. Fourth, minimum 10-year continuous operating tenure with documented Aurora service coverage. Firms acquired by national franchise networks (Authority Brands’ Benjamin Franklin Plumbing, Neighborly’s Mr. Rooter, Service Experts, Roto-Rooter, Wrench Group, Redwood Services, Master Trades Group, ARS) are excluded.
Frequently Asked Questions
How do I verify an Aurora plumber’s license?
Use the Colorado DORA State Plumbing Board public licensee database at dora.colorado.gov. Search by license number or business name. Confirm active status, classification, bonding, and insurance before authorizing work.
What credentials should an Aurora plumber hold?
At minimum: Colorado Master Plumber credential plus general liability insurance and workers’ compensation coverage. Specialty work (gas line, backflow prevention, fire sprinkler, sewer lateral) requires additional credential layers.
How can I tell if an Aurora plumber is locally owned versus a national rollup?
Check ownership disclosures and acquisition history. National franchise brands typically operate under parent-company branding. Search the firm name plus “acquired” or “parent company” to surface ownership structure. The four firms in this directory all run as independent locally-owned operators.
When should I call an emergency plumber in Aurora?
Burst pipes, sewer backups, gas leaks, no-water events, and water heater failures justify after-hours dispatch. Cold winter snaps drive freeze-burst pipe demand across the Denver Metro. Each firm in this directory offers either 24/7 emergency service or structured after-hours response.
