Booked mitigation jobs, not form fills.

Radon is invisible, odorless, and the second-leading cause of lung cancer. That makes your marketing fundamentally different from a general home services contractor. Your customer is not shopping for a nicer faucet or a lower utility bill. They are buying a health risk assessment and a fix for a problem they cannot see, taste, or feel. The sale depends on trust, urgency, and the credibility of your testing protocols and mitigation guarantees.

Most radon companies run on real estate transaction work. A home sale falls through, a buyer backs out, or a seller gets a surprise test result at the eleventh hour. That demand is real, but it is erratic. You cannot build a crew schedule around the closing calendar of every realtor in your service area. The companies that grow steadily are the ones who capture demand from homeowners who are not in a transaction at all, the ones who decide to test because they heard a public service announcement, read a news article, or saw a neighbor's mitigation system being installed.

Your Real Customer Is the Homeowner, Not the Realtor

Realtors send you business. They are an important referral source. But they are not your customer. They are an intermediary who wants a problem solved fast so a deal closes. They do not care about your brand, your service area growth, or your crew utilization. They care about a certificate of mitigation in under 72 hours.

If your marketing strategy is built entirely on realtor relationships and real estate agent referral fees, you are one market slowdown away from a dead month. When mortgage rates spike and transactions drop by 30 percent, so does your lead volume. The owner who built a book of business on realtor handshakes watches their pipeline evaporate. The owner who built a direct-to-homeowner marketing machine keeps crews busy through the slowdown.

Homeowners who call you directly are a different customer. They own the problem. They are not under a 48-hour escrow deadline. They have time to compare companies, read reviews, check your certifications, and ask questions about fan placement and pipe routing. They are more likely to buy a whole-house mitigation system at full retail price, not a negotiated realtor discount. And they are far more likely to become a repeat customer for testing in a new home, a rental property, or a relative's house.

Google Search Ads: Capturing the Moment of Awareness

The homeowner who searches "radon testing near me" or "radon mitigation cost" is in the middle of a decision process. They may have just received a test kit result, read a local news story about radon in their county, or had a friend recommend testing. They are not tire-kicking. They are looking for a credible company to solve a health problem.

Google Search Ads let you appear at the exact moment that search happens. You bid on the terms that signal intent: "radon mitigation system installation," "radon levels of 4 pCi/L what to do," "continuous radon monitor rental." You do not bid on "what is radon" unless you have a content offer that captures that traffic for retargeting later.

Your ad copy needs to answer the unspoken question: "Can I trust this company?" Mention your NRPP or NRSB certification. Mention your warranty on the mitigation system. Mention that you are licensed and insured. The homeowner is scared. Your ad should sound like a professional who has done this hundreds of times, not a salesman.

Google Local Services Ads: The Google Guaranteed Advantage

For radon work, Local Services Ads are nearly mandatory. Google places a "Google Guaranteed" badge next to your listing at the very top of local search results. You pay per lead, not per click. And Google vets your licensing and insurance before they let you run.

This matters because radon mitigation is a trust-based purchase. The homeowner is letting you drill a hole in their basement slab and install a fan that runs 24/7 for the life of the house. They need to believe you know what you are doing. The Google Guaranteed badge is a third-party credibility signal that no amount of website copy can reproduce.

The catch: LSA requires fast response times. If your CSR does not answer within a few minutes, the lead goes to the next provider. You need a system, a person or an automated triage, that picks up every LSA lead within minutes. Letting an LSA lead go to voicemail is throwing money away.

Radon Seasonality Is Real. Plan for It.

Radon testing follows a predictable seasonal curve. Testing volume spikes in the fall and winter when homes are closed up and indoor radon levels are highest. Homeowners who test in October and find elevated levels become mitigation customers in November and December. Spring and summer are slower for testing but can be busy for mitigation installations if the homeowner has been sitting on a test result from the previous winter.

You cannot treat every month the same. A flat monthly marketing budget wastes money in the off-season and starves you in peak season. You need a campaign calendar that shifts spend and channel mix by month.

Seasonal Campaigns: Timing the Spend

Your seasonal campaign for radon testing starts in late August. That is when homeowners are thinking about fall, sealing up the house, and running the furnace. Run Google Search Ads on "fall radon testing" and "winter radon test." Target homeowners in counties with known radon geology. Use Display Ads with retargeting to reach people who visited your site but did not book.

In November and December, your campaign shifts to mitigation. The testing leads from September and October who did not convert are now your highest-intent audience. Retarget them with a specific offer: "Winter mitigation installation, schedule now for priority service." Direct mail to the same audience with a simple card: "Your test showed elevated radon. We can fix it. Call for a quote."

January through March is your peak installation season. Your marketing job is to keep the pipeline full enough to maintain crew utilization without overbooking and disappointing customers. This is where customer reactivation shines.

Customer Reactivation: The Quiet Pipeline

Every homeowner who tested with you in the last three years is a reactivation lead. They tested once. They may have tested below the action level and forgotten about it. Or they tested high, got a quote, and did not pull the trigger because the timing was wrong.

A reactivation mailer or email sequence to that list is the highest-converting channel you have. The cost per booked job from a reactivation campaign is a fraction of what you pay for a cold lead. You already have their address, their test result, and their history. You are not introducing yourself. You are reminding them of a problem they already know about.

Send a letter in late September: "Your 2021 test showed 3.2 pCi/L. Levels can change. Retest this fall." Or send one in January to the list of people who tested high but did not mitigate: "We can still install at winter pricing. Your health risk has not changed."

The Commercial and B2B Side Is Underserved

Most radon companies focus entirely on residential work. Commercial radon testing and mitigation is a separate market with less competition, bigger job tickets, and longer sales cycles. Schools, daycare centers, office buildings, and multi-family properties are required to test in some states and strongly encouraged in others.

A commercial radon mitigation job for a 50,000 square foot school can run five figures. The decision maker is a facilities manager, a school superintendent, or a property management firm. They are not searching Google for "radon mitigation near me." They are responding to RFPs, attending trade shows, and asking peers for referrals.

Cold Email: Reaching the Commercial Buyer

Cold email is the most direct way to reach commercial decision makers. You need a targeted list of facilities managers, school district maintenance directors, and commercial property managers in your service area. Your email is not a sales pitch. It is a brief, factual message: "We specialize in radon testing and mitigation for commercial buildings. We are NRPP-certified and have completed work in schools and office buildings. If you need a proposal for your properties, reply to this email."

The key is volume and persistence. A single email gets ignored. A sequence of three to five emails over three weeks, with a follow-up phone call, turns a cold contact into a conversation. You are not spamming. You are providing a solution to a regulatory and health risk they may not have prioritized.

Direct Mail for High-Value Commercial Targets

Direct mail to commercial property addresses works because it is physical. A facilities manager gets hundreds of emails a day. They get maybe ten pieces of mail. A simple postcard or letter with your certifications, a map of your service area, and a phone number stands out.

Target commercial properties built before radon-resistant construction codes were adopted. Older buildings in radon-prone counties are your highest-probability prospects. Mail to the property address, not the corporate headquarters. The mail goes to the person who actually manages the building.

Your Google Business Profile Is Your Front Door

For residential radon work, your Google Business Profile is the single most important piece of digital real estate you own. It is the first thing a homeowner sees when they search for radon mitigation. It shows your rating, your reviews, your phone number, your hours, and your photos.

If your profile has three reviews and the last one is from two years ago, you are telling every prospect that you are a side hustle. You need a steady stream of reviews from every completed mitigation job. Ask every customer. Send them a link. Make it part of your closeout process.

Post to your profile weekly. A photo of a completed mitigation system. A short update about radon awareness month. A reminder about fall testing. Google rewards active profiles with higher placement in the map pack.

Retargeting: The Second Chance

Most homeowners who visit your website do not call on the first visit. They are researching. They want to know what a mitigation system looks like, how much it costs, and whether you are legit. They leave. They get distracted. They forget.

Retargeting brings them back. A display ad that follows them around the web for a week, showing your logo and a simple message: "Radon mitigation. Free estimate. Call today." The cost per impression is pennies. The conversion rate on retargeted visitors is multiples higher than cold traffic.

Pair retargeting with a content offer. A downloadable guide: "What Every Homeowner Should Know About Radon Mitigation." A video walkthrough of a typical installation. Give them a reason to come back to your site, and then retarget them until they call.

The Math of a Radon Marketing Budget

You are allocating dollars across channels to produce a predictable number of booked jobs per month. The cost per booked job is the only number that matters. You do not care about clicks, impressions, or cost per lead as standalone metrics. You care about how many jobs your crews install and what each job cost to acquire.

Start with your target. If you need ten mitigation jobs per month to keep two crews busy, and your average job ticket is $1,500, you need $15,000 in booked revenue per week. Your marketing budget should be 10 to 15 percent of that revenue, roughly $1,500 to $2,250 per week.

Allocate that budget across channels based on what works in your market. In a competitive metro area, Local Services Ads and Google Search Ads will take the largest share. In a smaller market where you are one of two providers, direct mail and reactivation may dominate. Test, measure, shift. The channel mix that works in Denver will not be the same one that works in Cedar Rapids.

Marketing Turnaround: When It Is Broken

If your marketing is not producing predictable leads, the problem is rarely a single channel. It is usually a system problem. Your website does not convert. Your CSR is not qualifying leads properly. Your follow-up is slow or nonexistent. You are spending money on channels that do not match your customer's buying behavior.

A marketing turnaround starts with an audit. What channels are you running? What is your actual cost per booked job on each one? Where are leads dropping out of your process? Are you losing them before they call, during the phone call, or after the estimate?

Fix the leaks before you add more spend. A 10 percent improvement in your close rate is worth more than a 10 percent increase in your ad budget. The fastest path to more revenue is not more leads. It is not losing the leads you already have.

The Long Game: Building a Radon Brand

The companies that dominate their market are the ones homeowners think of first when they hear the word radon. That is not an accident. It is the result of consistent, long-term investment in visibility and trust.

Sponsor a local health fair. Speak at a realtor association meeting. Write a column for the community newspaper. Put a radon test kit in every new home purchase in your county. Do the things that make your name synonymous with radon in your service area.

That brand equity protects you when a competitor opens up down the street. It protects you when Google changes its algorithm. It protects you when the real estate market slows down. The homeowner who knows your name and trusts your reputation does not need to comparison shop. They call you.

And that is the point. A marketing machine that produces predictable, profitable leads is not a luxury for a radon company. It is the difference between a crew that stays busy and an owner who spends every winter wondering where the next job is coming from. Build the machine. Run the numbers. Keep the pipeline full.
