Boring Businesses That Make Money

I hear about these businesses more often than you might expect in founder interviews, usually from people who tried something exciting first. The appeal is not the work itself. It is that the customer already knows they have the problem, already knows roughly what it costs to fix, and mainly wants someone who shows up. That removes the hardest part of most new businesses, which is convincing people they need you at all.

Why boring businesses keep working

Most new ventures fail on demand. Paul Graham’s essay on startup ideas calls solving a problem nobody has the most common mistake founders make. A broken air conditioner, a roach problem or a dirty office does not have that issue. The buyer is already motivated.

The second reason is competition for attention. Graham describes “schlep blindness,” the tendency of founders to avoid messy, tedious problems. It applies even more strongly to physical services than to software. Many people who could run a good pest control company would rather build an app.

The third reason is repeat business. Cleaning contracts renew. Pest control often runs on scheduled visits. Heating and cooling systems need maintenance and eventually replacement. Storage units are rented month after month. A customer won once can pay for years.

None of this means easy. Most of these businesses are hard work with thin room for error, and the founders who do well in them tend to be the ones who treat operations, scheduling and hiring as the real product.

The list: what makes each one work and the main catch

The figures below come from the Bureau of Labor Statistics Occupational Outlook Handbook and from trade associations. Two notes before reading them. First, BLS median pay figures describe wages for workers in the occupation, not profits for owners; the BLS notes its wage survey does not cover the self-employed. Second, job growth projections are a proxy for demand, not a promise about any one local market.

A closer look at each

Cleaning

Cleaning is the most accessible business on the list, which is both its strength and its problem. BLS projects only 2% growth for janitors and building cleaners from 2025 to 2035, slower than average, but the occupation is so large that it still expects around 321,800 openings a year, mostly to replace people leaving. For an owner, that turnover is the real challenge: staffing is the business. BLS also notes that office buildings are often cleaned in the evening when they are empty, so the work runs on odd hours.

The founders who make cleaning work usually pick a niche (medical offices, post-construction, short-term rentals) where reliability is worth paying more for, rather than competing on the lowest hourly rate.

Pest control

BLS counts about 108,700 pest control workers in 2025 and projects 6% growth over the decade, faster than the average for all occupations. Around 88% work in exterminating and pest control services firms, and about 5% are self-employed. The license requirement in most states, usually training plus an exam, is a cost of entry. It is also a filter that keeps the market from filling with weekend operators.

HVAC and plumbing

These are the strongest demand stories in the data. From 2025 to 2035, BLS projects 11% growth for heating, air conditioning and refrigeration mechanics, much faster than average, and 7% for plumbers, pipefitters and steamfitters, faster than average. Median wages in May 2025 were $61,010 for HVAC mechanics and $63,800 for plumbers.

The catch is the path in. The EPA requires nearly all HVAC technicians to be certified in refrigerant handling. Most states license plumbers, licensing often takes 2 to 5 years of experience plus an exam, and some states require master plumber status before you can hold a contractor license. A founder without the trade either has to earn it or partner with someone who has it. Buying an existing shop with licensed staff is a common route for that reason.

Landscaping and grounds care

About a fifth of grounds maintenance workers are self-employed, according to BLS, which tells you small operators are a normal part of this market. Growth is projected at 5% from 2025 to 2035. The obvious catch is seasonality: BLS notes that many jobs are busier in spring, summer and fall, and some workers add snow removal in winter. Applying pesticides also needs a license in most states.

Laundromats

The Coin Laundry Association, the industry’s trade group, estimates about 29,500 coin laundries in the United States. It points to features investors like: no inventory, no receivables, leases that often run 10 to 25 years, and steady demand from renters and people without good laundry facilities at home. It says stores typically sell for three to five times net cash flow.

Treat these as a trade group’s figures, which the association itself says it cannot guarantee. The catch is in the details it also lists: performance depends on demographics, store condition, equipment, pricing, parking and nearby competition. Its own equipment guidance puts the useful life of topload washers at 5 to 8 years and most other machines at 10 to 15 years, so replacement is a cost you plan for, not a surprise.

Self-storage

The Self Storage Association describes itself as representing the industry’s 49,000 US facilities. Storage appeals because the daily labor is light and rent arrives monthly. But this is a property business first. Most of the risk sits in the price of land or the building, the cost of borrowing, and how many new facilities open nearby. Founders without capital or real estate experience usually enter by buying a small facility or partnering, not by building one.

Bookkeeping

Bookkeeping is the useful counterexample. Every business needs clean books, and the work recurs every month. Yet BLS projects a 6% decline in employment for bookkeeping, accounting and auditing clerks from 2025 to 2035, because software now automates much of the routine work. BLS also notes the role is shifting toward analysis and advising clients. A bookkeeping business can still work, but the version that lasts sells judgment, cleanup and advice, not data entry.

Boring businesses to be careful with

Some boring businesses are sold to founders more than they are built by them. Vending machines are the classic case. In 1997 the FTC announced a multi-state crackdown, Operation Yankee Trader, on sellers of candy vending machine ventures that advertised high monthly income and promised help finding locations that, according to the FTC, never materialized.

The protection today is the FTC’s Business Opportunity Rule. Sellers must give you a one-page disclosure document at least seven days before you sign or pay, and any earnings claim needs its own written statement showing how many buyers actually achieved it. If a “turnkey” boring business comes without those papers, that tells you what you need to know.

Start, buy or franchise

Many boring businesses are easier to buy than to start, because the hard parts (licenses, trained staff, a customer list, a location) already exist. The SBA sums up the trade-off: buying gives you more control and less guidance, while a franchise gives you more guidance and less control, under contracts that usually favor the franchisor. If you buy, the SBA suggests checking licenses and permits, zoning, environmental rules for any property, and getting an attorney and accountant to review the financials and agreements.

If you start from scratch, the advantage is cost and learning. The disadvantage is that you spend the first year building what a buyer would have paid for.

How to choose among them

The right boring business depends less on the industry average than on your own position. Ask four questions:

1. Do you already have the license or skill, or a realistic way to get it?
2. Can you reach the first twenty customers without paid ads, through people you know, a trade you worked in, or a neighborhood you understand?
3. Is it labor, capital or credentials that limit you? Choose the business whose bottleneck you can handle.
4. Would you still run it in three years if it worked? Boring businesses reward patience, and they punish owners who treat them as a stepping stone they resent.

From there, score your candidates with the criteria in How to Evaluate a Business Idea, then test demand before signing a lease or buying equipment, as covered in How to Validate a Business Idea. The wider question of where ideas come from is in the pillar guide, How to Come Up With a Business Idea. If you are weighing a small, owner-run service business on purpose, Lifestyle Business covers that choice.
