HAIL BRINGS THE STORM.
SOLICITORS BRING THE SECOND ONE.

Companies obtain real-time radar data mapping the exact path of hail impact zones and deploy canvassing teams directly to those zip codes — often before the storm system has cleared the state. What follows is relentless, aggressive, and in many cases deceptive.

🌨️
Storm Chasers Track Your Neighborhood
Roofing contractors use live hail radar to identify impacted zip codes and deploy teams within hours of a storm. Front Range homeowners report being approached by multiple contractors in a single day — all before their insurance adjuster has even called.
#1 Solicitor Type in Denver
Solar Teams Use Deception
Denver solar solicitors have been documented wearing Xcel Energy vests and falsely claiming to be utility employees. They request personal information — including full name, date of birth, and bank account numbers — under the guise of "verifying Xcel accounts."

Frustration Has Reached a Breaking Point
In April 2023, a Highlands Ranch resident was charged after constructing a booby trap on his front steps that injured a door-to-door salesman. A Douglas County judge issued an arrest warrant. This is what happens when homeowners have no real recourse.

Signs Don't Work. Even Good Laws Fall Short.
Colorado cities have some of the strongest municipal ordinances in the country — yet enforcement remains nearly impossible. By the time a resident calls police, the canvasser has moved to the next block. The laws exist. The protection doesn't.

I'm so sick of door to door sales people. Solar, pest control, window washing, cleaners, yard work — I get dozens a week. They just ignore the No Soliciting sign completely.

THE FRONT RANGE SUBURBS GETTING HIT HARDEST

Canvassing teams don't knock randomly — they use demographic mapping and radar impact zones to target specific communities. These are the Front Range suburbs with the highest documented solicitor activity.

Highlands Ranch
Homeowner frustration reached criminal levels — a resident built a booby trap targeting a solicitor. CBS News covered the story in April 2023.
Extreme Frustration
Castle Rock
Implemented a formal No Knock List (Municipal Code 5.04) due to persistent solicitation. One of the most advanced registry systems in the country.
Registry Exists
Aurora
Residents report aggressive D2D activity across all categories. City passed updated solicitor regulations in September 2023 due to resident pressure.
New 2023 Ordinance
Arvada
Frequent Reddit complaints about solicitors explicitly ignoring posted "No Solicitors" signs. City makes it unlawful to solicit at signed homes — rarely enforced.
Sign Ignored
Thornton
High solicitor activity across roofing and solar categories. City codified solicitor rules through Ordinance No. 3760, January 2026.
Jan 2026 Ordinance
Westminster
Police actively advise residents to post "No Solicitor" signs — indicating the problem is persistent enough to require official guidance.
Police Advisory
Lakewood
Adopted a new door-to-door soliciting ordinance in December 2025 in direct response to escalating resident complaints.

COLORADO HAS THE BEST LAWS.
THEY STILL AREN'T ENOUGH.

The Front Range has some of the most advanced municipal solicitor frameworks in the country — digital registries, background checks, financial penalties. And yet homeowners still report dozens of solicitors per week. Enforcement is the gap.

Castle Rock, CO
Municipal Code 5.04 (Ordinance 2013-43) — maintains a digital No Knock List requiring a $35 fee and background check. Solicitors must review the list daily and face strict penalties for knocking on registered addresses.
✓ Digital Registry + Background Check
Aurora, CO
Municipal Code Sections 86-226 through 86-233 — requires solicitors to obtain a license and carry a city-issued ID card. Updated September 29, 2023 following resident complaints.
✓ License + City ID Required
Commerce City, CO
Sections 12-5005 & 6-2001 — classifies unauthorized solicitation as a civil infraction carrying fines up to $2,650. Among the highest financial penalties for solicitation violations in Colorado.
✓ Fines Up to $2,650
Lakewood, CO
New door-to-door soliciting ordinance adopted December 9, 2025 at City Council meeting — clarifying hours and conduct expectations in response to resident complaints.
✓ New Dec 2025 Ordinance
Thornton, CO
Ordinance No. 3760 adopted January 27, 2026 — codifying solicitor rules and sign-based opt-out protections for residents.
✓ Jan 2026 Ordinance
Denver, CO
Municipal Code 47-18c makes it unlawful to solicit at any place displaying a visible sign indicating solicitation is undesired. Enforcement relies entirely on police availability.
⚠ Sign Law — Hard to Enforce
⚠️
The enforcement gap: Even Castle Rock's advanced digital registry can't stop a solicitor who hasn't checked the list. Police cannot proactively remove permitted solicitors from sidewalks and rarely arrive before the canvasser has left the neighborhood. KnockBlock creates the private enforcement layer these laws are missing.

WHO'S KNOCKING ON FRONT RANGE DOORS

Ranked by prevalence and aggressiveness across the Denver metro and surrounding Front Range communities.

01
Roofing & Storm Chasers
The dominant threat on the Front Range. Companies use live radar to identify hail impact zones and deploy teams within hours of a storm. Interstate Roofing and Premier Roofing are among the documented firms using aggressive post-storm canvassing tactics across Denver suburbs.
Extreme Threat
02
Solar Sales
Highly deceptive tactics documented across the metro. Solar solicitors have been caught wearing Xcel Energy vests and falsely claiming to be utility employees while requesting sensitive personal and financial information. Denver Solar Brokers cited for ongoing violations of Municipal Code 47-18a.
High Threat
03
Smart Home & Security
Year-round D2D deployments from companies including Smart Home Pros and ADT. Security solicitors target planned communities and new developments, often implying neighborhoods have elevated crime risk to generate urgency.
High Threat
04
Pest Control
Summer saturation campaigns targeting planned communities. Aptive Environmental and Moxie Pest Control documented using "neighborhood discount" tactics and ignoring posted signs across Highlands Ranch, Centennial, and Parker.
Moderate Threat

THEY'VE BEEN WHERE YOU ARE

These are documented community complaints from Denver and Front Range homeowners — pulled from Reddit, local news, and community groups.

I'm so sick of door to door sales people. Solar, pest control, window washing, cleaners, yard work — I get dozens a week. The No Soliciting sign means nothing to them.

r/Denver — May 5, 2023

Solar reps were wearing Xcel Energy vests and asking for my date of birth and bank account information. They said it was to verify my account for community solar credits. It felt like identity theft, not a sales pitch.

A Highlands Ranch homeowner was so fed up with solicitors that he built a physical booby trap on his front steps. A door-to-door salesman was injured. A judge issued an arrest warrant. This is where we are.

WHY WILL KNOCKBLOCK WORK
WHEN THE BEST LAWS DON’T?

Colorado has the strongest municipal solicitor ordinances in the country — background checks, city badges, fines up to $2,650. A Highlands Ranch homeowner built a booby trap out of frustration. The laws are there. Here’s why KnockBlock works where they fall short.

01
It Operates Where Laws Can’t Reach.
Castle Rock’s digital No Knock List requires solicitors to check it daily and act in good faith. Solar reps wearing Xcel Energy vests and requesting bank account numbers aren’t checking lists. KnockBlock is a private system — no good faith required. Your registration works whether the solicitor knows the law or not.
02
It Changes the Signal at Your Door.
Front Range homeowners have posted signs, registered with cities, and called police. Solicitors still come daily. A KnockBlock founding sign communicates something signs and city stickers can’t: this address is part of a verified, documented private registry. That’s a different calculation for a canvasser than a generic sticker.
03
Verified Contractors Still Reach You.
After years of deceptive storm chasers and solar reps impersonating Xcel Energy, Denver homeowners deserve a way to identify legitimate contractors before opening the door. KnockBlock’s verified directory gives you that — companies that meet verification can still approach registered homes. The ones racking up complaints can’t.

THE PRIVATE PROTECTION LAYER THE FRONT RANGE IS MISSING

Colorado has the best municipal ordinances in the country. Solicitors still ignore them. KnockBlock creates what the city can't — a verified, private protection layer that puts the burden back on the contractor.

01
Register Your Address
Your home is entered into the KnockBlock protected registry. You receive a physical founding sign — verified, not just printed.
02
Solicitors Are on Notice
Unverified solicitors who approach KnockBlock-registered homes know they're on record. The sign communicates what a generic sticker never could.
03
Verified Contractors Keep Access
Legitimate contractors who complete KnockBlock verification can still approach registered homes — giving you a trusted local directory and giving them earned access.
