Frederick contractors at a glance

In Frederick, HomeProFax tracks 249 contractor profiles, which is the 45th-highest count for any city in Colorado, 73 of them with a lapsed license. 70% of them show an active license on file, above the Colorado-wide figure of 54% for the profiles we hold.

Because Colorado leaves roofing, general contracting and HVAC to cities, we also pull municipal license lists. Frederick firms hold 79 licenses on them (Arvada (33), Aurora (26) and Thornton (20)), among them 3 roofing licenses, 18 general contractor licenses and 9 HVAC/mechanical licenses. State licensing boards are the main source here: we count 141 electrical licenses (23 masters, 69 journeymen, 14 residential wiremen) and 72 plumbing licenses (22 masters, 26 journeymen) in Frederick.

Most entries are individual tradespeople (160), not companies. Only 22 active electrical contractor and 9 active plumbing contractor registrations are based here, and those are the businesses that can sell electrical or plumbing work to you directly. Board discipline: 6 Frederick records have a DORA discipline flag (4 electrical, 2 plumbing). 4 belong to licenses that are still active, so a current license alone doesn't rule out past discipline. Experience runs deep: half of the licensed pros here were first licensed in 2008 or earlier, and 18 active licenses date from before 2000. 25 are new since 2024.

We matched 7 Frederick companies to Colorado Secretary of State filings: 4 in good standing and 3 delinquent or dissolved. A dissolved entity can't back a warranty, so check the status before you sign. The busiest ZIP codes are 80530 (112), 80504 (95), 80516 (40), and 5 ZIPs are represented in total.

387 permits from City of Boulder open data trace back to 7 contractors based in Frederick. The leaders are Lord & Reynolds Electrical Services, Inc. (294), Axis Electrical Services, LLC (36), Titus Electrical Services (34). The newest is dated 2026-09-18, and at least 11 were issued in the past year. Most are electrical permit (152), fire permit (15), building permit - non-residential (10). These are jobs these firms did in Boulder or Denver. Frederick doesn't publish permits in a portal we cover yet, so no permits shown doesn't mean no permits pulled.

Hail, roofs and your contract

Frederick sits on the Front Range, in the heart of "Hail Alley." The Rocky Mountain Insurance Information Association says the region usually sees three or four catastrophic hailstorms a year, and the damaging season runs from mid-April to mid-September. After a storm, Colorado law lets you cancel an insurance-paid roofing contract within 72 hours of a written claim denial (C.R.S. 6-22-104), and a roofer may not offer to pay or waive your deductible (C.R.S. 6-22-105).
