How to tell if an agency understands basement finishing

Late February is a sensible time for a basement company to interview agencies. The winter’s jobs are framed or nearly finished, the thaw has not yet shown anyone where their walls leak, and the September booking window is far enough away that a new plan can be built properly rather than rushed. Most pitches you will hear are written for remodeling in general. Basements differ enough that a handful of questions will separate the agencies that have done this work from the ones guessing, and that includes us.

Ask which Local Services category they would use

Google’s Local Services Ads have no basement finishing category. An agency that knows the trade will say so before you ask, then walk you through the options. General contractor is the nearest fit for finishing. Foundations services covers waterproofing basements and crawl spaces, not finishing. Carpenters covers drywall and remodeling work.

Each choice carries consequences. Under General contractor, Google requires a business check and an owner check for every advertiser, general and professional liability insurance, state-level business and owner licenses where the law calls for them, and a public, verified Business Profile. Google’s own estimate for that screening is three to four weeks after the paperwork goes in. Since last October, every advertiser carries the same Google Verified badge, which replaced the old guarantee and screening badges.

Then ask the follow-up question: what happens when that General contractor listing rings with someone who wants a new house built or a roof replaced? Google’s credit rules now exclude leads tagged “job type not serviced” or “geo not serviced”, so those calls stay on your bill. A good answer covers narrow job types, a tight service area and a person reviewing every lead each week. A vague answer means you will pay for the misfits.

Ask where they would draw your service area, and why

An agency should know that basements are regional before it suggests a single keyword. NAHB’s analysis of 2024 Census data found basements under 67.2% of new single-family homes in New England, 62.3% in the West North Central states and 50.3% in the East North Central states, while 97.9% of new homes in the West South Central division sat on slabs. A radius drawn by drive time alone can pour money into suburbs where nobody has a basement to finish.

Google’s own rules set the outer limits: one Business Profile for each staffed location, and a service area within about two hours of driving time. Inside those limits, the primary category outweighs every other setting you control. Whitespark’s 2026 Local Search Ranking Factors survey ranks it first among map pack factors. Ask the agency what your primary category should be, which secondary categories it would add, and how it would prove the change worked.

Ask what will be on your site besides the gallery

Photos sell basements, but the questions that get a homeowner to pick up the phone are about code and process. Listen for these in any agency’s plan:

• An egress page. Under the 2021 International Residential Code, a basement bedroom needs an escape opening of at least 5.7 square feet with a sill no higher than 44 inches, and a well of at least 9 square feet, with a fixed ladder or steps once it is deeper than 44 inches.
• A moisture and radon page, built on the code’s dampproofing rule and on EPA’s advice to test for radon before converting a basement and again afterward.
• A permit page written for your county, with the inspections in the order they happen.
• Your license number, everywhere your state wants it.

That last item is not decoration. Minnesota’s Department of Labor and Industry says license numbers must appear on business cards, contracts and all other advertising including websites, and on building permit applications. Pennsylvania’s Attorney General requires registered home improvement contractors to print their number, in the format PA123456, in advertisements, contracts, estimates and proposals. Michigan requires a license for any job totaling $600 or more in labor and materials. If an agency writes a single ad before asking for your number, it has not worked in those states.

Ask how they would earn reviews, and what they would refuse to do

A basement company finishes far fewer jobs in a year than a service trade runs calls in a month, so each review carries more weight. In BrightLocal’s Local Consumer Review Survey, out earlier this month, nearly half of consumers (47%) said they would pass over a business with fewer than 20 reviews, and three in four (74%) said only reviews from the last three months matter. The same survey found 45% now use ChatGPT and other generative AI tools for local recommendations, up from 6% a year earlier, and 82% read AI-generated summaries of reviews.

The answer you want is a request after every final walkthrough, a reply to every review and nothing paid. The FTC’s final rule of August 2024 bans offering money or any other reward on the condition that a review comes out positive or negative. An agency that suggests gift cards for five stars is offering you a federal problem along with the reviews.

What the first 90 days and the monthly report should show

For a basement company, order matters, because the leads are few and the jobs are large. A plan we would be comfortable signing:

• Weeks 1 to 2: call and form tracking by source, with every lead tagged as a full finish, a bathroom, an egress job or an apartment.
• Weeks 1 to 6: the profile’s category and service area set, separate pages for finishing, egress and bathrooms, and the Local Services application started if you hold the licenses.
• Weeks 2 to 8: galleries sorted by room type, a price range drawn from your own jobs, and the code and permit pages.
• Weeks 6 to 12: a follow-up sequence for consults who are not ready yet, and referral asks to past clients.

The monthly report should follow a lead all the way to a contract: calls answered and missed, site visits booked, estimates sent and signed, each split by source and by project type. Impressions and clicks belong in a footnote. If the report cannot tell you which source produced last winter’s signed basements, it is not measuring your business.

What to do this month

• Write down your license or registration number, then check every page, profile and ad that carries your company name.
• Ask each agency you interview which Local Services category it would use and how it would handle wrong-job leads.
• Ask to see the service area it would draw, town by town, with its reasoning.
• Count your Google reviews from the last three months, and if there are only a few, start asking at every walkthrough this week.
• List last winter’s signed jobs with the source of each one, so any agency’s plan can be judged against real numbers.

The agency worth hiring for a basement company talks a little like an inspector and a little like an estimator: it knows the code, the regional split and the platform rules, and it can explain how each one moves the next signed job. Our basement finishing page shows how we would plan the year, and our Google Business Profile work covers the category and service area questions above.
