Are there any general maintenance service marketplaces that focus on odd jobs and small repairs?

Yes — there are several general maintenance/service marketplaces that cover odd jobs, small repairs, and handyman-type work.

Common examples include:

• TaskRabbit — good for odd jobs, furniture assembly, minor repairs, mounting, moving help, etc.
• Thumbtack — broad marketplace for local pros, including handymen, cleaners, plumbers, electricians, and small repair jobs.
• Angi (Angie’s List) — home service marketplace with handymen and repair pros.
• Handy — focuses on home cleaning and handyman-style tasks in many areas.
• Mr. Handyman — more of a service brand than a pure marketplace, but useful for small repairs and maintenance.
• Local Facebook groups / Nextdoor — not formal marketplaces, but often used to find people for odd jobs and quick fixes.

If you want, I can also give you:

1. a list by country/region, or
2. which one is best for residential vs. commercial maintenance.
