The Three Risks of the 'Gig Economy'

⚠️

Mechanic's Liens

In Williams Bay, if an unverified contractor doesn't pay their supplier, **you** are liable. The supplier can place a lien on your home, forcing you to pay for materials twice.

🏗️

Mandatory Tear-Downs

If work is done without inspection in Williams Bay, you may be forced to tear down walls or decks to prove compliance. The cost to 'do it twice' is astronomical.

🏚️

Property Damage Caps

If a cheap pro drops a tree on your roof, they can't pay for it. You pay the deductible and higher premiums. Verified Pros have General Liability for this exact reason.

Permit Requirements

Most exterior projects in Williams Bay (Decks over 30", Fences over 6', Additions) require a building permit from the local building department. Always ensure your contractor pulls the permit in their name.
