Most people assume a real business needs a storefront. These seven boring garage businesses need one shelf and one cheap tool. Each one fixes gear the customer already owns: a torn window screen, a slick golf grip, a snapped glove lace, a broken racquet string, rusty ski edges, a grinding reel or a frayed bow string. Most towns have few or no shops doing this work, and the gear wears out on a schedule, so the same customers come back.

This list runs from the easiest garage business to the best in the category, and every entry shows the income first, before any cost. Prices below come from published operators and are not guarantees.

Key Takeaways

  • All seven businesses run on one model called the Owned Gear Fee: the customer already paid for the expensive part, you keep it working, and wear brings them back.
  • The cheapest start is window and door screen repair, with a rescreening kit at about $13 at Home Depot. A typical shop charge starts at $40 a screen.
  • The biggest month on the list is bow restringing and tuning: about $2,360 from 12 string jobs and 8 setups.
  • Racquet restringing has the most repeat visits, since an old rule says to restring as many times a year as you play in a week.
  • Before picking one, ask three questions: does the customer already own and use the gear every season, can you learn the tool on your own stuff first, and does the whole business fit on one shelf?

The Owned Gear Fee: Why These Boring Businesses Work

Boring business ideas that make money tend to share one trait: they sell a small service, not a product. Harry, who runs a moving crew and sees whole garages every Saturday, noticed that golf bags with slick grips, skis with rusty edges and bows with frayed strings sit untouched because nobody fixes them. He calls the model the Owned Gear Fee. You do not sell a product and you do not carry inventory. You charge a small fee to keep gear people already own in play, and because that gear wears out on a schedule, the same customer returns.

This is for educational purposes only and is not financial advice. Prices change from town to town, and some cities ask for a home business permit, so check your local rules before you start. For more low-cost ideas, see our guide to 6 boring businesses that make money under $500 to start.

1. Window and Door Screen Repair (The Easiest Start)

What it pays: Tiny Luster in Tampa charges from $40 for a standard window screen and $55 for a large one. Colfax Glass puts professional rescreening at $25 to $75 a screen, with most standard sizes at $35 to $55. San Diego Mobile Screens lists $45 to rescreen a standard window and $95 for a sliding screen door.

Forty screens at $40 is $1,600 a month. That is only about four driveways at ten screens a house. Colfax Glass says a batch of ten screens from one customer brings in about $350 to $650.

The one cheap tool: a Prime-Line screening kit with mesh, spline and rolling tool, about $13 at Home Depot. Colfax puts materials at $5 to $15 a screen, so on a $40 screen you keep roughly $25 to $35 before your time. Breeze Screens, a San Diego repair shop, says a standard window screen takes about 10 to 15 minutes on the bench.

How to start: in week one, rescreen your own windows and time each one. In week two, set a price near $40, create a Google Business Profile and post before-and-after photos in local Facebook groups. In week three, ask neighbors, realtors and property managers for batches of five to ten screens. Home Depot's Pro Referral page lists $20 to $30 a window when several are done at once, so a bundle price feels normal. In week four, finish your first paid batch and ask for reviews.

The demand is real: Screenmobile runs a national franchise around screen repair, with a typical price of $75 to $110 a screen in Gretna, Nebraska. Smart screen pros price the whole house, not one screen, because nobody wants one new screen next to nine faded ones.

2. Golf Club Regripping

Golf Pride, the grip maker, says most golfers should regrip at least once a year, or about every 40 rounds. The National Golf Foundation counts 29.1 million on-course golfers in the US in 2025, and each carries about 13 grips that wear out.

On the GolfWRX forum, golfers put the cost at about $5 for the grip plus $5 for labor. On Reddit's golf forum, the highest labor price one poster had seen was $4 to $5 a club. At $5 a club in labor, 13 clubs is $65 a set, and 20 sets a month is $1,300, with the grips billed on top.

GolfWorks sells a Grip Essentials Kit for about $70, with solvent, tape, a hook blade and a rubber shaft clamp. A cheaper supplies kit is about $15. Add a bench vise and you are set up. Regrip your own bag first, then take flyers to a local league night or the driving range. Month one might be three or four sets; by spring, 20 sets a month could be within reach.

3. Baseball and Softball Glove Relacing

GloveRelace.com charges $60 for a full relace, $70 with new padding and $45 for partial work. Golomb in New York charges $100 for a full fielder's glove and $115 for a catcher's or first base mitt. One eBay seller charging $48 a glove has sold 82 of them.

The Sports and Fitness Industry Association counted 15.6 million baseball players in 2021, plus about 6 million slow pitch and 2.1 million fast pitch softball players. A glove is the one piece of gear a player hates to replace, because they broke it in. Fifteen gloves at $60 is $900 a month; twelve at $100 is $1,200. Spring is the rush.

The cost may be the lowest on the list. Franklin's Doctor Glove relacing kit is about $25 at Walmart, and a pro relacing needle runs about $38 at The Glove Lab. The Craftsman's Works offers an optional glove relacing certification and directory listing. Relace your own old glove, then a friend's, then show up where the parents are: youth leagues, travel teams and local Facebook groups.

4. Tennis Racquet Restringing

StringGoat puts labor at about $10 to $25 a racquet, with a total including string around $30 to $40. Superstringer, a home-based pro shop in Chesapeake, Virginia, posts $27.50 for stringing labor alone. The USTA says US tennis reached 27.3 million players in 2025.

Aspen Hill Club repeats an old rule of thumb: restring as many times a year as you play in a week. A player who plays three times a week needs three string jobs a year. Forty racquets a month at $35 is $1,400. String runs about $7.50 to $17.60 a racquet, so most of the bill is your labor.

On a Reddit tennis thread, a longtime home stringer says about 30 minutes on a drop weight machine, while newer stringers say 45 minutes to an hour. The one cheap tool is a drop weight machine: the Klippermate runs about $379 new, StringGoat models an entry drop weight setup at about $430 and a crank machine at about $900. One Reddit poster paid about $300 on eBay plus $75 shipping. The USRSA Certified Stringer test is about $279 for non-members, including a year of membership. It is optional, but serious players notice it.

To find customers, go where players are: tennis clubs, leagues, high school coaches and local Facebook groups. Ask one club if you can keep a drop-off box at the front desk, string the racquet that night and return it the next morning. Real families do this: Stringers Corner in Apple Valley, Minnesota, has been a home-based service run by the Sommers family since 1983. A pro tip: write the tension and string on a small tag inside the throat, so the player comes back to you.

5. Ski and Snowboard Tuning

Resort shops set the price. Crystal Mountain charges $80 for a standard tune and $95 for a performance tune. Christy Sports charges $75 to $80 for a full tune and $50 for an edge and wax, and The Starting Gate lists $85. Christy also puts wax-only jobs at about $25 to $30, a cheap first offer.

The National Ski Areas Association says US downhill skiing and snowboarding have historically hovered around 9.5 million people. Twenty-five tunes at $80 is $2,000 in a peak winter month. IdeaCrystal estimates about $650 to $1,000 for vises, edge tools and a hot waxer. Wax-only takes about $50 to $80 in tools. Big belt grinders run thousands, even used, so skip them; hand tuning is the garage version.

Tune your own skis, then a friend's, and post in local ski club and Facebook groups before the first snow. Plenty of skiers would rather drop skis off down the street than wait in line at the mountain.

6. Fishing Reel Cleaning and Repair

Valley Reel Works charges from $25 to service a freshwater reel, $35 for saltwater spinning and $40 to $45 for lever drag. Doug's Reel Repair starts at $40 a reel and $50 for a two-speed. Rod and Reel Repair Guy in Valley, Alabama, lists an overhaul clean at $30, parts extra.

The Recreational Boating and Fishing Foundation says 57.7 million Americans went fishing in 2023. Twenty-five reels at $40 is $1,000 a month. At Valley Reel Works, customers pay for parts up front, so you are not floating inventory.

SmallBusinessIdea puts a full start at $500 to $3,000, but the core is cheap: Harbor Freight sells an ultrasonic cleaner for about $100 and a precision screwdriver set for about $15. Small tackle shops that stopped doing repairs can send people your way.

The bench rule: test every item before it leaves the bench.

Harry learned this the hard way. A neighbor asked him to clean a reel, and he packed it with too much grease. The drag felt sticky and the reel came back. He wiped the gears, oiled them again and tested the drag himself. The neighbor returned the next month with two more reels. Harry also took a lesson from Robert Pirsig's Zen and the Art of Motorcycle Maintenance (1974): quality comes from the person who actually cares about the thing in front of them. He wrote one word on tape above his bench: CARE.

7. Bow Restringing and Tuning (The Best on the List)

Pine and Marsh, which writes about archery pro shops, says a new string and cable set runs about $80 to $180 installed. Setup sessions bill at $50 to $150 and tuning at $20 to $80. Hill Country Bow Garage advertises a complete bow tune from $100 and new strings and cables from $100.

Twelve string jobs at $130 is $1,560. Add eight setups at $100 and the month reaches $2,360, the biggest on the list. Hoyt, the bow maker, recommends a new string every two years or 2,000 shots, whichever comes first, and sooner if it shows wear. Every bow is on a clock.

The Archery Trade Association counted 9.9 million US bowhunters and 17.6 million recreational archers in its 2020 survey. ArcheryRangeAtlas lists over 41,000 ranges and sporting stores, but only about 770 flagged as pro shops. Pine and Marsh cites the trade association's count at about 2,500 to 3,000 pro shops. Millions of archers, a few thousand benches.

The one cheap tool is a bow press. Lancaster Archery sells the portable Ram Ratchet Loc press for about $125, the bench-mounted Last Chance EZ Green for $479 and the Last Chance EZ Press for $689. Mike Countryman runs Arrow and Pine Archery in Prineville, Oregon, as an appointment-only, garage-based pro shop, after about a year of research and testing.

Learn on your own bow first, then do friends' bows before you charge anyone. Target archery clubs, bowhunter Facebook groups and pro shops that fill up before the season. A pro tip: check the bow maker's approved press list before you buy. Hoyt publishes press guidance and warnings.

What a Combined Month Can Look Like

In Harry's example, screens paid for the first year, and before his second fall he bought a bow press and a waxing iron. His best month came in month 20: 25 ski tunes at $80 ($2,000), 15 bow string jobs at about $130 ($1,950), 30 racquets at about $40 ($1,200) and 12 reel cleanings at $25 ($300). That totals $5,450. After about $413 for string, wax and parts, he kept about $5,037, while still running the moving crew. This is one example, not a promise.

How to Choose Your First Business

Run three filters. Does the customer already own the gear and use it every season? Can you learn the tool on your own stuff first, for free? Can the whole business fit on one shelf in your garage? Three yeses mean your first tag could go on the shelf this month. The cheapest start is screens, the most repeat visits come from racquets, and the biggest month is the bow. If you prefer a different lane, our article on rental business ideas is a good next read.

One free step for the next 24 hours: walk into your own garage and find one item with a torn screen, a slick grip or a frayed string. Then look up who fixes it near you, what they charge and how far you would drive. That one search tells you whether your town is waiting for a shelf like Harry's.
