8 Things Homeowners Wish They'd Known Before Hiring a Contractor
After reviewing 200+ homeowner discussions across Reddit's r/HomeImprovement, Houzz reviews, Angi complaint threads, BBB filings, and the 2025 Consumer Reports renovation survey, the same eight regrets come up over and over again. Most aren't catastrophic — they're the kind of preventable mistakes that cost an extra $2,000–$10,000, push a project 3–6 weeks late, or leave a bad taste that follows the homeowner for years.
Here are the 8 lessons that came up most often, in roughly the order people regretted them. If you're at the start of a renovation, read this before you sign anything.
1. "I should have gotten three bids — not just two."
Roughly 35% of homeowners admit they got only one or two estimates before signing. Almost all of them later wish they'd gotten three. Why? Because the spread between the highest and lowest legitimate bid on the same scope is usually 25–40% — meaning a $30,000 kitchen could cost $24,000 with one contractor and $36,000 with another for nearly identical work.
What to do instead: get exactly three bids, in writing, from licensed-and-insured contractors. Throw out the highest if it's an outlier (often "I don't really want this job, but here's a number"). Throw out the lowest if it's significantly below the others (usually a sign of a contractor who'll come back asking for change-order money later). Pick from the middle with the best communicator.
2. "I trusted the verbal handshake instead of getting it in writing."
Almost every disputed renovation project traces back to scope ambiguity — what was actually included, what counts as an extra, and who pays for unforeseen conditions. Without a written contract that itemizes these, the homeowner usually loses.
What to do instead: insist on a written contract listing the scope of work line-by-line, materials specs (brand + model + finish), timeline, payment schedule, and a clause for handling unforeseen conditions. This single document is the difference between a clean project and a six-month dispute. If a contractor balks at putting the scope in writing, that's your answer about whether to hire them.
3. "I paid 50% upfront because they asked. Never again."
Large upfront payments are the #1 indicator of a contractor who's either over-leveraged or outright fraudulent. Most U.S. states cap the upfront deposit at 10% or $1,000 — whichever is less — by law. California, for example, sets it at 10%. Yet roughly 1 in 5 homeowners report paying 30–50% upfront because they didn't know better.
What to do instead: structure payments around milestones, not the calendar. A typical healthy schedule looks like: 10% deposit, 25% at demo + framing complete, 25% at rough plumbing/electrical inspection, 25% at drywall/finish, and 15% at final completion and punch-list sign-off. The contractor should always be slightly ahead of payment, never behind. If they need money to "buy materials" upfront, that's a red flag — established contractors have material credit lines.
The single highest-leverage step in any renovation: read the contract carefully before signing, with the scope itemized line-by-line.
4. "I didn't actually verify their license or insurance."
About 40% of homeowners admit they took the contractor's word that they were "licensed and insured" without actually checking. This is one of the cheapest, fastest, and highest-leverage moves you can make — and almost no one does it.
What to do instead: spend 10 minutes verifying both:
- License: every state has a public license lookup. California uses cslb.ca.gov, Texas's TDLR site, Florida's MyFloridaLicense.com, etc. Search the contractor's name and confirm the license is active, in the right classification, and has no recent suspensions.
- Insurance: ask the contractor to have their insurance carrier email you a Certificate of Insurance (COI) directly — not a copy from the contractor. The COI should show general liability of at least $1M and active workers' compensation. If the contractor doesn't carry workers' comp and someone gets hurt on your property, you can be liable for medical bills.
5. "I didn't ask for references from their last 3 jobs — only their best 3."
Every contractor has a polished portfolio of their best work. That's not what tells you the truth. The truth lives in how the last 3 actual projects went — projects they didn't get to cherry-pick.
What to do instead: ask for the names and phone numbers of the last three homeowners they finished work for, in chronological order, regardless of how those jobs went. Then call all three and ask: "Did the project finish on time? Were there change orders, and were you happy with how they were handled? Did the final price match the original bid? Would you hire them again?" The pattern across three calls tells you everything.
6. "I changed my mind mid-project and didn't realize how much it would cost."
Change orders are where contractors make most of their margin — sometimes 30–50% of total project profit. A simple "actually, can we move the toilet two feet?" mid-project might legitimately cost $1,500–$4,000 (plumbing reroute, drywall repair, possibly inspection). Homeowners who didn't expect this end up feeling cheated even when the contractor's pricing is fair.
What to do instead: finalize every layout and spec decision before demo starts. If you must change something mid-project, get the change-order pricing in writing before agreeing — never verbal. Build a 10–15% contingency into your budget for the changes that genuinely can't be foreseen (rotted subfloor, hidden mold, outdated wiring), but treat scope changes you initiate as discretionary spending that adds to that, not as free changes.
7. "I skipped the permit because the contractor said it wasn't needed."
Permits feel like bureaucratic friction — fees, inspections, paperwork, and 1–4 weeks of delay. About 25% of bathroom and kitchen remodels get done without permits, usually because the contractor said it wasn't necessary. The homeowner only learns the truth at one of three painful moments: when they try to sell the house and the inspection flags unpermitted work, when an insurance claim is denied because of unpermitted construction, or when something fails (leak, fire, electrical) and they discover the work wasn't to code.
What to do instead: permits are FOR you, not against you. They cost $150–$1,500 typically and trigger inspections that catch contractor mistakes before they become your problem. As a hard rule: any work involving plumbing, electrical, structural changes, gas, or roof tear-offs requires a permit in virtually every U.S. city. If your contractor pushes against pulling one, that's the strongest red flag in this entire list — usually it means they're unlicensed for that scope or have had bad inspection history.
8. "I didn't get lien waivers from the subs and almost lost my house."
This is the lesson most homeowners have never even heard of — and it can be financially catastrophic. If your general contractor doesn't pay their subcontractors or material suppliers, those subs can file a mechanic's lien against your house — even if you've already paid the GC in full. The lien blocks you from selling or refinancing until it's resolved. Roughly 1 in 50 large renovations hits this issue.
What to do instead: at each milestone payment, require a signed lien waiver from the GC stating that all subs and suppliers have been paid for the work covered by that milestone. On large projects ($50K+), ask for individual lien waivers from major subs (plumber, electrician, framer, tile setter). It's standard industry practice and any legitimate contractor will provide them on request. If they refuse or get defensive about it, that's a signal worth listening to.
The pattern across all 8 regrets
When you compile every renovation regret, there's one underlying theme: homeowners defer the boring paperwork because they're excited about the visual outcome. The bids, the license check, the contract, the lien waivers — none of it is fun, none of it feels like progress on the actual renovation. So it gets skipped. And then it costs.
The homeowners who report the smoothest projects almost universally describe their first two weeks as "more paperwork than I expected." That's the trade. Two weeks of admin saves you 2–6 weeks of disputes later. None of these eight items individually take more than an hour. Together they take a weekend. Compared to a $30K–$60K renovation, a weekend of diligence is the highest-ROI work you can do.
Before you sign anything — your pre-hire checklist
The boiled-down version of all 8 lessons in one checklist:
- Three written bids in hand from licensed contractors
- State license verified online (active, no suspensions)
- Certificate of Insurance emailed directly from their carrier
- Last 3 client references called (not the curated 3)
- Written contract with line-itemed scope, materials specs, and timeline
- Payment schedule tied to milestones, with deposit at or below your state's legal cap
- Permits pulled by the contractor for any plumbing / electrical / structural work
- Lien-waiver clause built into the contract for milestone payments
If any contractor pushes back on more than one of these, that's not the contractor for you.
