If a salesperson left your kitchen table this week — a roofer after a hail storm, a solar installer, a windows pitchman, a basement-waterproofing contractor — and you signed something you are not sure about, you may have only a few days to back out cleanly. Move now.
Colorado law gives consumers a short, sharp right to cancel certain in-home solicitation sales. Used correctly, it costs you nothing. Used incorrectly — or used late — it can be very hard to recover.
The three-day rule, plainly stated
Under Colorado consumer-protection law governing home-solicitation sales, a buyer generally has the right to cancel — without penalty and without giving a reason — within three business days after signing a contract that was solicited at the buyer's home. The rule exists specifically because high-pressure in-home sales create predictable buyer's remorse, and the legislature has decided you should have a cooling-off period to think it through.
Three pieces of that sentence carry weight:
Home solicitation. The rule applies to sales solicited at your home (or, in many cases, away from the seller's regular place of business). It is the location of the sale that triggers the right.
Three business days. Weekends and Colorado state holidays do not count. The clock starts the business day after you sign.
Without penalty. You owe nothing — no restocking fee, no "preparation" fee, no commission. The seller's costs are the seller's problem.
There are exceptions. Real estate sales, insurance, and certain emergency repairs are typically outside the rule. But for the great bulk of in-home sales — roofs, windows, siding, gutters, solar, water treatment, security systems, vacuum cleaners, encyclopedias if anyone still sells them — the right applies.
What the seller was supposed to give you
Colorado law requires the seller to give you, at the time of the sale, a specific written notice of your right to cancel. The notice typically must:
Be on a separate, conspicuous document
State the three-business-day deadline
Include a tear-off or detachable cancellation form
Identify the seller's mailing address for cancellation
Be in the same language used in the sales presentation
How to cancel — actual mechanics
If you are inside the three-business-day window, do all of the following today:
Write the cancellation in plain language. "I am canceling our contract dated [date] for [service]. Please refund my deposit." Sign and date it.
Send it certified mail with return receipt to the seller's address listed on the notice (or on the contract). Yes, certified mail still matters. The return receipt is your proof of timely cancellation.
Send the same letter by email to whatever contact address you have. Two-track delivery is the cheap insurance.
Do not let the work begin. If the seller has already scheduled an install or a delivery, call and cancel it. If a crew shows up despite your cancellation, document it and turn them away.
Stop payment if you can. If you paid by check, call your bank. If you paid by credit card, dispute the charge immediately and reference the home-solicitation cancellation right in your dispute. If you paid cash — that is a harder recovery, but the law still entitles you to a refund.
Save everything. The signed contract, the cancellation notice the seller gave you (or did not give you), your cancellation letter, the certified-mail receipt, the dispute submission to your card issuer, any communications with the seller.
The seller is generally required to refund your money within a defined period (Colorado law sets a window, typically 10 days) and to pick up any goods delivered or, at the seller's option, to allow you to keep them at no cost if they are not retrieved within the statutory window.
High-pressure tactics — what to watch for
Most home-solicitation problems I see follow the same pattern. Recognizing the pattern is half the defense.
Storm-chasing roofers and gutter installers after a hail event, often pressuring same-day signatures and same-day "free" inspections
Solar installers with elaborate financing structures the homeowner does not fully understand at signing
Basement-waterproofing and foundation-repair contractors showing dramatic photos of unrelated failures
Water-treatment salespeople demonstrating "contamination" in your tap water that is actually a chemical reaction the seller introduced
HVAC and "free inspection" upsells that turn into multi-thousand-dollar replacement contracts before the salesperson leaves
If any of these landed in your kitchen this week and you signed something, the three-day clock is running. Cancel first; reflect later. Cancellation costs nothing. Buyer's remorse with no cancellation costs everything.
If you are past the three days
The cancellation right is not your only protection — it is just the cleanest. If you are outside the three-day window, several other paths remain open, depending on the facts:
Misrepresentation and consumer-protection claims. If the salesperson made specific false statements — about your existing systems, about manufacturer rebates, about the work that was needed — the Colorado Consumer Protection Act and the common law of fraud provide remedies independent of the three-day right.
Unconscionability and high-pressure-sale defenses. Contracts signed under genuinely coercive conditions can be challenged on those grounds. The bar is high but the doctrine is real.
Defects in the work itself. If the work was performed and the work is defective, you are now in construction-defect territory rather than cancellation territory. See our Colorado construction defect dispute resolution guide for what comes next.
The right move depends entirely on which path the facts support. If you are inside the three days, cancel today. If you are outside the three days, save every document and call before you talk to the seller again. The conversation you have with the seller after consulting a lawyer is dramatically different — and dramatically more effective — than the one you would have on your own.
