Every homeowner has a story. The contractor who took a large deposit and disappeared. The electrician who left the job half-done. The roofer whose work failed inspection and who couldn't be reached afterward. The renovation that ended in small claims court.

These aren't rare outcomes — they're common enough that most homeowners approach contractor hiring with a mixture of anxiety and resignation. The problem is that most homeowners don't have a systematic way to vet contractors before they commit. They rely on gut feel, a referral from a friend, or the first contractor who actually called them back.

A systematic approach to contractor vetting reduces these outcomes dramatically. Here's the checklist.

Before You Even Call a Contractor

Define the scope in writing first

The most expensive words in home improvement are "while you're here." Scope creep is the primary driver of cost overruns, and scope creep happens when the scope isn't defined before work begins. Before calling anyone, write down exactly what you want done, what materials you want used, what the finished result should look like, and any constraints (timeline, access, disruption to the household).

The more specifically you can define the scope, the more accurately you'll be able to compare bids — and the harder it is for a contractor to expand scope without your explicit agreement.

Know your budget range before requesting bids

You don't need to disclose your budget to contractors, but you need to know it internally. This lets you quickly disqualify bids that are outside your range and understand whether the bids you receive are realistic or whether your scope needs adjustment.

The License and Insurance Verification Most Homeowners Skip

Most homeowners ask to see a contractor's license. Almost none of them verify it. The difference matters.

A contractor can show you a license card that expired two years ago, belongs to someone else, or covers a different trade than the work you're hiring for. Verifying independently — through your state's contractor licensing board website — takes 5 minutes and confirms the license is current, in the contractor's name, and covers the work being performed.

The same logic applies to insurance. An insurance certificate is only as good as the policy it represents — and policies can be canceled after the certificate is issued. For projects over $5,000–$10,000, a brief call to the insurer to verify the policy is active is time well spent.

The unlicensed contractor trap: Unlicensed contractors typically bid lower because they don't carry the overhead of licensing fees, insurance premiums, and compliance costs that licensed contractors do. If your project requires a permit (most structural, electrical, plumbing, and HVAC work does), an unlicensed contractor can't pull it — which means either it goes unpermitted (a significant liability when you sell), or you're left holding the permit in your name with a contractor you can't verify.

Contracts: What Must Be in Writing

Any project over a few hundred dollars should have a written contract. For significant projects (anything over $1,000–$2,000), the contract should include:

When to Use a Managed Marketplace vs. Finding Your Own Contractor

For straightforward, defined-scope projects in your area, a managed bid marketplace handles several steps of the vetting process for you — license and insurance verification, competitive bidding, and escrow payment management. You get multiple bids from contractors who've already been vetted, with payment protection built in.

For specialized or complex projects where you need a contractor with specific experience (custom millwork, historic restoration, high-end kitchen builds), a direct search with the full vetting checklist above may produce better results than a marketplace's available pool.

Boojee Maintenance: vetted contractors, escrow protection

Post your project, receive competitive bids from pre-vetted contractors, and release payment only after your sign-off on completed work.

Post a Project

The homeowners who never get burned by contractors aren't luckier than the ones who do. They're more systematic. They verify what they're told, define scope before asking for bids, hold final payment until work is done, and don't let urgency or salesmanship override their vetting process.

The checklist above is the entire system. Use it every time, and the odds of a bad contractor experience drop to near zero.
