How to Hire a Remodeling Contractor in Denver (Without Getting Burned)
Hiring a contractor is the most important decision you'll make in your remodel. A good one makes the process almost enjoyable. A bad one turns it into a nightmare that costs you money, time, and sanity.
After years of working in the Denver market, here's what actually matters when choosing a contractor—and the red flags that should make you walk away.
The Denver Contractor Landscape
Denver has a lot of contractors. Some are excellent. Some are terrible. Most are somewhere in between.
The challenge: the excellent and terrible ones often look similar at first glance. Both have websites. Both give estimates. Both say the right things. The difference shows up in execution—and by then you've already paid deposits.
Here's how to tell them apart before you commit.
What to Look For
1. Proper licensing
In Colorado, general contractors need a state license for projects over $500. Specialized trades (electrical, plumbing) require separate licenses. Denver has additional requirements.
Ask for: License number. Then verify it at the Colorado DORA website (dora.colorado.gov). This takes two minutes and rules out unlicensed operators immediately.
Red flag: "I'm licensed, don't worry about it" without providing the actual number.
2. Insurance that actually protects you
A contractor should carry:
- General liability insurance: Minimum $1 million. Covers damage to your property.
- Workers' compensation: Covers injuries to workers on your site. Without this, you could be liable if someone gets hurt.
Ask for: A certificate of insurance naming you as additionally insured. Call the insurance company to verify it's active.
Red flag: "I'm insured" with resistance to showing proof. Or insurance that expired last month.
3. An established local presence
Fly-by-night contractors exist. They blow through town, collect deposits, do shoddy work (or disappear), and move on. You want someone with roots.
Look for:
- Physical address (not just a PO box)
- Years in business in Denver (5+ is good, 10+ is better)
- Online presence that shows actual projects
- Reviews on multiple platforms over time
Red flag: New company with no history, contractor who "just moved to Denver," or no online footprint at all.
4. References you can actually contact
Any contractor can cherry-pick happy clients. The question is whether they have enough of them.
Ask for: 5-10 references from projects similar to yours. Contact at least three. Ask:
- Did the project finish on budget?
- Did it finish on time?
- How did they handle problems?
- Would you hire them again?
Red flag: "I don't give out client information" or only two references who are clearly friends/family.
5. A detailed written estimate
A proper estimate isn't one number on a napkin. It's a document that breaks down:
- Labor costs
- Material costs (with allowances specified)
- Permits
- Timeline
- Payment schedule
- What's included and what's not
The allowance trap: Watch for unrealistically low allowances. If the estimate shows $50/sq ft for tile but every tile you like costs $15/sq ft, that low number is meaningless.
Red flag: Vague estimates, verbal-only quotes, or pressure to sign before you've had time to review.
What to Watch Out For
The lowball bid
If one bid is dramatically lower than others (20%+ difference), something is wrong. They're either:
- Missing something major
- Planning to hit you with change orders later
- Cutting corners on materials or labor
- Not paying their subs properly (which creates lien risk for you)
Rule of thumb: Get three bids. Throw out the lowest if it's far below the others. The best contractor is rarely the cheapest.
Pressure to decide immediately
"This price is only good today" or "I've got another big job starting next week" are high-pressure tactics. Good contractors have steady work; they don't need to pressure you.
Walk away from: Any contractor who won't give you time to think, compare bids, or check references.
Large upfront deposits
Standard in Denver: 10-30% upfront deposit, with the rest tied to milestones. Never pay more than 30% before work begins.
Absolutely not: Paying 50%+ upfront, paying in cash with no paper trail, or paying for materials yourself to "save the markup."
No written contract
A contract protects both parties. It should include:
- Scope of work (detailed)
- Total price with payment schedule
- Timeline with key dates
- Change order process
- Warranty terms
- Permits (who pulls them)
- Insurance requirements
- Dispute resolution
Red flag: "We don't need a contract, we'll just shake on it." Yes, you do need a contract. Always.
The "while we're at it" escalation
Some contractors make their money on change orders. They bid low, then "discover" problems that require expensive fixes. Or suggest additions once work is underway when you're too committed to say no.
Protection: Detailed scope upfront, clear change order process, and willingness to push back on unnecessary additions.
The Interview Process
When you meet potential contractors, you're interviewing them. Treat it that way.
Questions to ask:
About their business:
- How long have you been in business in Denver?
- What types of projects do you specialize in?
- How many projects do you typically run simultaneously?
- Who will be on-site daily? (Not the owner—the actual crew)
- What subcontractors do you use regularly?
About your project:
- Have you done projects similar to mine?
- What challenges do you see with my project?
- How do you handle permits?
- What's your typical timeline for this type of work?
- How do you handle communication during the project?
About problems:
- Can you tell me about a project that went wrong and how you handled it?
- What's your warranty on workmanship?
- How do you handle disputes?
Listen for: Specific answers, not vague reassurances. Willingness to discuss problems (everyone has them). Realistic timelines, not overly optimistic promises.
The Contract Details That Matter
Scope of work
The more detailed, the better. "Install new kitchen" is not a scope. You want:
- Cabinet specs (brand, style, finish)
- Countertop material and edge profile
- Appliances (model numbers)
- Tile specifications and layout
- Fixture brands and models
- Paint colors
Anything not specified can become a point of conflict later.
Payment schedule
Standard structure:
- 10-30% at signing
- 25-30% at rough-in (framing, electrical, plumbing in wall)
- 25-30% at cabinet installation / major milestone
- 10-15% at final completion
Never pay the final payment until everything is done to your satisfaction, including punch list items.
Change order process
Changes happen. The contract should specify:
- How changes are requested and approved (in writing)
- How change order pricing is calculated
- Your right to refuse changes without penalty
Timeline
Include start date, estimated completion date, and key milestones. Understand that delays happen—but the contractor should communicate proactively and have a plan to get back on track.
Warranty
Minimum one year on workmanship. Many quality contractors offer more. Manufacturer warranties on materials are separate.
During the Project
Communication expectations
Set these upfront:
- Weekly check-ins (phone, email, or in-person)
- How to reach the project manager for urgent issues
- When decisions need to be made and by whom
Daily log
Your contractor should maintain a daily log of work completed, materials delivered, and any issues encountered. This becomes important if disputes arise.
Change orders
Get every change in writing with pricing before the work happens. Don't approve anything verbally and expect the original price to hold.
Inspections
Your contractor pulls permits and schedules inspections. You should know when inspections happen and receive copies of passed inspection documents.
Paying on time
When milestones are met, pay promptly. Good contractors have cash flow needs and prompt payment maintains a good working relationship.
The Permit Reality
In Denver, most remodeling projects require permits. The contractor should pull them.
Why this matters:
- Insurance may not cover unpermitted work
- Unpermitted work creates problems when selling
- Inspections catch dangerous mistakes
- It's the law
Your responsibility: Verify permits were actually pulled. The city posts permit information online—check that your address shows an active permit.
If Things Go Wrong
Even with careful contractor selection, problems can happen. Here's how to handle them:
Document everything
Photos, emails, texts, dates, descriptions of issues. If it's not documented, it didn't happen.
Communicate in writing
Phone calls are fine for quick questions. Important issues should be confirmed in writing via email.
Follow the contract dispute resolution process
Most contracts specify how to handle disputes—often starting with direct negotiation, then mediation, then legal action.
Know your options
- Negotiate: Most issues can be resolved through conversation
- Withhold final payment: You can withhold payment for incomplete/defective work
- Mediation: A neutral third party helps you reach agreement
- Colorado Contractors Board: File a complaint for serious violations
- Legal action: Last resort, but sometimes necessary
Mechanic's liens
If your contractor doesn't pay their subcontractors, those subs can file a lien against your property—even if you paid the contractor. Protect yourself by:
- Getting lien waivers from subs as payments are made
- Paying with joint checks (to contractor and sub together) for large amounts
- Verifying subs are being paid before releasing final payment
Quick Reference: Red Flags Summary
Walk away if you see:
- No license or won't provide license number
- No insurance or won't show certificate
- No references or vague about past projects
- Significantly lower bid than competitors
- Pressure to decide immediately
- Requests for more than 30% upfront
- Resistance to written contract
- Cash-only payment requests

- Can't clearly answer questions about your project
The Bottom Line
Hiring a contractor is about trust. You're inviting someone into your home and giving them significant money to improve it. Take the time to vet them properly.
The process:
- Get recommendations from friends, neighbors, or online reviews
- Check licenses and insurance
- Get 3+ detailed written bids
- Interview your top candidates
- Check references
- Read the contract carefully
- Start work only when everything is documented
A few hours of due diligence can save months of headaches and thousands of dollars.
