Your general contractor is the single most important person in any major home renovation — their competence, honesty, and management skill determines whether your project comes in on time, on budget, and without defects. These essential tips protect you from the most common contractor pitfalls.
Most states require general contractors to hold active contractor licenses. Verify through your state contractor board that the license is current, covers the scope of your project, and has no disciplinary actions. Also confirm they carry $1M+ general liability insurance and workers' comp — never waive this requirement.
Your contract must specify scope, materials (by brand and model where applicable), timeline, payment schedule, and warranty terms. Just as importantly, every subsequent change — however minor — must be captured in a signed change order with cost and timeline impact. Verbal agreements are unenforceable.
Many GCs win bids with impressive portfolios but then delegate all on-site work to subcontractors you've never met. Ask specifically who will be on-site daily, how the GC supervises subcontractor work quality, and how often you'll see the person you hired versus their crew.
Ask specifically: if something fails or looks wrong after completion, how long is your warranty and how do you respond to warranty claims? State law typically requires a minimum 1-year workmanship warranty. Contractors who resist discussing post-completion responsibilities are telling you something important.
Ask for 3 references from projects completed within the past 2 years of similar scope to yours. Visit at least one completed job to see finish quality in person — a walkthrough reveals floorwork, trim work, and paint quality that photographs routinely disguise with lighting and angles.
Search your contractor on the Better Business Bureau, your state contractor licensing board's complaint database, and local court records for liens or judgments. A pattern of unresolved complaints, expired licenses, or multiple project liens is disqualifying regardless of how low their bid is.
Structure payment in installments tied to completion of specific, verifiable milestones: foundation complete, framing inspected, rough electrical approved, etc. This schedule gives you financial leverage throughout the project and prevents contractors from taking your money and slowing work once their next job demands attention.
Provide identical project specifications to at least three contractors and compare bids line by line — not just total price. Dramatically lower bids typically reflect missing scope items, lower-grade materials, or planned use of unlicensed subcontractors. Understanding what's different between bids is as important as the prices themselves.
State law in many jurisdictions limits contractor deposits to 10% or $1,000 (whichever is less) for home improvement contracts. Any contractor demanding 30–50% upfront before demonstrating any work should be declined — substantial advance payments are the primary tool of fraudulent contractors.
Retain 5–10% of total project cost until the punch list — a documented list of items requiring correction or completion — is fully resolved. This retention is your most powerful leverage for ensuring every detail is addressed before the financial relationship concludes.
Your contractor should pull all required permits and manage all inspections — this is a legal requirement and a quality safeguard, not optional overhead. Contractors who suggest skipping permits to 'save money' expose you to massive risk: unpermitted work can require demolition and prevents sale of your home.
Agree upfront on daily work hours, how waste is handled and contained, who has property access, and how you'll communicate (daily end-of-day text, weekly site meeting). Contractors who establish and respect clear protocols treat your home with the same care they'd want in their own renovation.
