5 Questions to Ask Before Hiring
These questions cut through the sales pitch and surface the information that matters. Write them down — bring them to every consultation.
- 1
How many plumbers projects like mine have you completed in the last year?
Volume and recency matter. A provider who handles dozens of similar cases per year has refined their process and is less likely to encounter surprises. Ask for specific numbers — vague answers like "many" are a yellow flag.
- 2
Can you provide references from clients with similar needs?
References from comparable projects are far more useful than general testimonials. When you call references, ask: Was the work completed on time? Were there unexpected costs? Would you hire them again?
- 3
What does your process look like from start to finish?
A professional who can clearly walk you through each step of their process demonstrates genuine expertise. Vague or evasive answers suggest a lack of structure — or an intention to make changes after you've signed.
- 4
What is your availability and expected timeline?
Unrealistic timelines and poor availability are leading causes of client dissatisfaction. Get the projected timeline in writing. Ask who will be your primary contact and how quickly they respond to questions.

Red Flags to Watch For
These warning signs appear frequently in cases where consumers report a poor experience — or worse, fraud.
High-pressure sales tactics
"This price is only good today" is a classic manipulation technique. Reputable plumbers professionals don't need to pressure you into an immediate decision. Take as much time as you need.
No verifiable reviews or references
If you can't find independent reviews on Google, Yelp, or BBB — and the provider can't supply references — that's a serious concern. New businesses should be transparent about their background.
Unable to provide proof of insurance
A legitimate professional carries liability insurance and can provide a Certificate of Insurance on request. If they can't or won't — walk away.
Significantly lower bid than all competitors
What to Expect to Pay
Pricing varies by location, complexity, and provider tier — but these ranges give you a baseline for evaluating quotes.
Typical Plumbers Cost Range
$200-$5,000
Basic / Entry-Level
Straightforward scope, no complications. Ideal for standard projects with clear requirements.
Mid-Range ← Most Common
Moderate complexity. Expect a thorough process, quality materials, and a defined warranty or guarantee.
Premium / Complex
High-stakes or specialized work. Premium providers often include additional services and faster response times.
* Cost ranges are national averages. Your actual quote will depend on your location, the severity of the issue, and the provider's tier. Always confirm pricing in writing before work begins.
Check Contractor License & Insurance
Most states require plumbers contractors to carry a state license, liability insurance, and workers' compensation coverage.
- 1.Look up contractor license status through your state's contractor licensing board
- 2.Verify the license is in your state and covers the scope of work
- 3.Request a Certificate of Insurance (COI) naming you as an additional insured
- 4.Confirm workers' comp coverage so you're not liable for on-site injuries
- 5.Check the Better Business Bureau and state consumer protection office for complaints
Getting Multiple Quotes
The single most effective way to protect yourself financially is to get competing quotes before committing to a plumbers professional.
How many quotes?
Get a minimum of 3 quotes for any project. Five is better for large or complex work. This gives you a statistically meaningful range and exposes outliers in either direction.
What to compare
Don't just compare the bottom-line number. Compare what's included: materials spec, warranty length, timeline, cleanup, and follow-up support. Identical prices can represent very different value.
Timing matters
Off-peak season often brings lower prices — providers are more flexible when demand is lower. Non-emergency work scheduled 2–4 weeks out typically costs less than same-day bookings.
Use quotes as leverage
Once you have quotes in hand, it's reasonable to go back to your preferred provider and ask if they can match a competitor's price. Most professionals will work with you rather than lose the job.

Frequently Asked Questions
Common questions from consumers choosing a plumbers professional for the first time.
How many plumbers quotes should I get?
Get at least 3 written quotes for any project over $500. This gives you a realistic price range, helps you spot outliers (suspiciously low bids often cut corners), and gives you leverage in negotiations.
Should I hire the cheapest contractor?
Not automatically. The lowest bid can indicate underinsurance, unlicensed workers, or plans to use substandard materials. Evaluate the full picture: license status, reviews, warranty terms, and what's included in the quote.
What should a written contract include?
The contract should specify scope of work, materials (brand and grade), start and completion dates, payment schedule, warranty terms, and a process for handling change orders. Never pay more than 10–30% upfront.
What is a lien waiver and do I need one?
A lien waiver is a document where the contractor (and subcontractors) waive their right to file a mechanic's lien on your property after payment. Request lien waivers for every payment milestone on projects over $2,000.
Can I verify a contractor's insurance myself?
Yes. Ask for a Certificate of Insurance (COI) and call the insurer directly to confirm the policy is active. Don't accept a COI that is expired or lists a different company name.
