The 10 Common Mistakes When Choosing a Contractor & How to Avoid Them

A successful remodel begins well before construction. It starts with selecting the right contractor and creating a planning process that turns your ideas into a clear, realistic scope of work.

Your contractor will spend weeks or months working in and around your home. They will learn how your family uses the space, coordinate numerous decisions, manage subcontractors and suppliers, and help you navigate the unexpected conditions that can arise during remodeling.

Price matters, but it is only one part of the decision. Experience, planning, communication, financial stability, craftsmanship, and personal fit can have an even greater effect on your experience and the final result.

Here are ten common contractor selection mistakes—and the positive steps you can take instead:

‍

1. Treating a Preliminary Estimate as a Complete Project Price

Homeowners understandably want to know what a remodel will cost. A reputable contractor should be willing to discuss a preliminary budget range early in the conversation.

The mistake is assuming that a quick, complimentary estimate represents a thoroughly developed construction price.

Major remodeling projects require numerous details to be investigated and documented, including:

  • Existing structural and site conditions
  • Architectural and engineering requirements
  • Permit requirements
  • Material and finish selections
  • Subcontractor pricing
  • Product lead times
  • Allowances (placeholder dollar amount set aside for items you haven’t selected yet) and specifications
  • Work that may be concealed behind existing walls
  • Protection, demolition, cleanup, and site restoration

Developing an accurate project price can require many hours of design, investigation, trade input, and estimating. A contractor who gives you a firm number before understanding these details may be making assumptions that later become change orders.

What to do instead

Ask for a reasonable preliminary range to determine whether the project and your available budget are generally compatible. If they are, move into a defined planning or pre-construction phase. That process should produce a clearer design, specifications, trade pricing, and a more reliable construction proposal.

Helpful question: “What information do you need before you can provide a dependable project price?”

‍

2. Overlooking Communication and Personal Fit

Your relationship with a remodeling contractor can be surprisingly personal. Their team will be working inside your home, sometimes while you and your family ontinue living there.

A contractor may have excellent technical skills but could still be the wrong fit if communication feels strained or your priorities are not being heard.

Pay attention to how the contractor interacts with you during the initial meetings:

  • Do they listen before offering solutions?
  • Do they explain things clearly and respectfully?
  • Are they curious about how you live?
  • Do they respond to questions directly?
  • Are they comfortable discussing budgets?
  • Do they respect your home, family, schedule, and pets?
  • Are they willing to tell you when an idea may not work?

You do not need to agree on every detail. However, you should feel that you can have candid conversations and work through difficult decisions together.

What to do instead

Evaluate the contractor’s communication style as carefully as you evaluate the proposal. Ask who will be your primary contact, how frequently you will receive updates, and how questions and decisions will be documented.

Helpful question: “When an unexpected issue arises, how do you communicate the options, costs, and effects on the schedule?”

‍

3. Comparing Prices Without Comparing Scope

Obtaining more than one proposal can be a responsible way to understand the market. In fact, the Oregon Construction Contractors Board (Oregon CCB) advises consumers to acquire multiple bids rather than agreeing to services immediately.

The problem occurs when homeowners compare only the bottom-line numbers. Two proposals may describe substantially different projects. One might include engineering, permits, protection, cleanup, premium materials, and realistic allowances. Another may leave those items unclear or exclude them entirely.

A low proposal is not necessarily wrong, and a high proposal is not necessarily better. The important question is whether each contractor has priced the same scope, materials, service level, and risk.

What to do instead

Create aside-by-side comparison that examines:

  • Included and excluded work
  • Material specifications
  • Product allowances
  • Design and engineering
  • Permit responsibilities
  • Demolition and disposal
  • Site protection and cleanup
  • Utility work
  • Project management
  • Warranty coverage
  • Contingencies and assumptions

The Oregon CCB recommends obtaining a written contract that clearly describes the work, materials, costs, and anticipated start and completion dates. See the Oregon CCB consumer guidance.

Helpful question: “What is specifically excluded from your proposal that I should include in my total project budget?”

‍

4. Relying Only on Online Reviews

Online reviews can help you identify potential contractors, but they should not replace direct reference checks. Reviews rarely provide the complete story of how a contractor plans projects, manages budgets, handles schedule changes, or supports clients after construction.

What to do instead

If you can, speak with two or three previous clients whose projects are comparable to yours. Ask:

  • Did the contractor treat your family and home respectfully?
  • How well did the team communicate?
  • Was the original budget realistic?
  • Were change orders explained and documented?
  • How were delays or unexpected conditions handled?
  • Was the job site kept reasonably clean and safe?
  • Was the punch list completed promptly?
  • Did the contractor respond to warranty concerns?
  • Would you hire the company again?

If appropriate, ask whether you can see a completed project. Contractors must protect their clients’ privacy, so an in-person visit may not always be possible. Photographs, detailed case studies, and conversations with past clients can still provide valuable insight.

‍

5. Failing to Verify Licensing, Bonding, and Insurance

Even a strong personal referral should be independently verified.

In Oregon, contractors performing construction work for compensation generally must be licensed by the Construction Contractors Board. Licensed contractors are required to carry a bond and insurance, and their public record may include complaint or disciplinary history.

What to do instead

Use the official CCB license search to confirm that...

  • The license is active.
  • The licensed business name matches the company in your contract.
  • The CCB number is correct.
  • The contractor holds the appropriate endorsement.
  • Bonding and insurance information is current.
  • Complaint or disciplinary information has been reviewed in context.

The CCB notes that a complaint does not automatically mean a contractor is untrustworthy. Consider the contractor’s time in business, the nature of the issue, and—most importantly—how the contractor responded and whether it was resolved. See the Oregon CCB license-checking guidance.

You can also contact the CCB at 503-378-4621 if you need help interpreting a license record.

‍

6. Hiring an Unlicensed Contractor to Reduce Cost

An unlicensed contractor may offer a lower price because the company is not carrying the same insurance, bonding, administrative, training, or regulatory costs as a legitimate contracting business. That apparent savings can create substantial risk.

If defective or incomplete work leads to a dispute, your options may be much more limited. Oregon’s residential complaint process generally applies to work performed by a licensed contractor and includes strict notice and filing deadlines. See the Oregon CCB consumer-protection information.

What to do instead

Hire a properly licensed contractor and confirm the license independently—even when the company was recommended by someone you trust.

For specialized plumbing, electrical, mechanical, or other regulated work, ask how the contractor confirms that the appropriate licensed trades and permits will be used.

Helpful question: “Will every subcontractor and trade professional working on my project hold the licenses required for their portion of the work?”

‍

7. Rushing Into Construction Before Planning Is Complete

Excitement can create pressure to begin demolition quickly. But construction is usually not the best time to discover that a beam is required, a desired product has along lead time, or the design exceeds the available budget.

Thorough planning helps identify important questions while they can still be resolved with drawings and conversations instead of field changes.

The planning phase may include:

  • Measuring and documenting existing conditions.
  • Developing space plans.
  • Evaluating structural requirements.
  • Investigating utilities.
  • Selecting materials and fixtures.
  • Reviewing permit requirements.
  • Obtaining subcontractor and supplier input.
  • Updating the budget as the design develops.
  • Establishing a preliminary construction schedule.

Planning cannot eliminate every surprise, especially when remodeling an older home. However, it can substantially reduce avoidable surprises.

What to do instead

Ask the contractor to explain the entire planning process before signing a construction agreement.

Helpful question: “What decisions, drawings, selections, and investigations will be completed before you establish the final construction scope and price?”

‍

8. Allowing Design and Construction Planning to Become Disconnected

Architects and interior designers bring valuable creativity, technical knowledge, and design expertise to a project. Contractors contribute knowledge about constructability, site logistics, sequencing, trade availability, and current construction costs.

Problems can develop when these disciplines work separately for too long.

A design may meet the homeowner’s vision but become difficult to build within the available budget. Conversely, allowing cost to drive every decision too early can prevent the design team from finding more creative solutions.

What to do instead

Create a collaborative team in which design, construction, and budget information inform one another from the beginning.

A design-build contractor can provide an integrated process under one organization. Alternatively, an independent architect, designer, and contractor can work very successfully when their responsibilities are clear and the contractor provides cost and construct-ability feedback at defined milestones.

Helpful question: “How will the designer, contractor, engineers, and trade partners collaborate as the design and budget develop?”

‍

9. Choosing a Contractor Without Relevant Experience

Remodeling is not one universal specialty. A contractor who excels at decks or straightforward kitchen updates may not be the right choice for a structural whole-home remodel, a complex addition, an ADU, or an aging-in-place project.

Relevant experience helps a contractor recognize challenges sooner and develop solutions that support the project’s long-term purpose.

For example, aging-in-place remodeling involves more than installing a grab bar. It may require an understanding of circulation space, lighting, floor transitions, reach ranges, accessible bathing, future mobility needs, and structural preparation for later adaptations.

What to do instead

Ask for examples of projects comparable in scope and complexity to yours. Discuss:

  • How many similar projects the company has completed.
  • Who on the team has the relevant experience.
  • What challenges occurred and how they were solved.
  • Whether the company holds applicable training or certifications.
  • How the finished work has performed over time.

Credentials such as Certified Aging-in-Place Specialist or ADU-specific training can be valuable, but credentials should complement—not replace—relevant completed-project experience and satisfied clients.

‍

10. Signing a Vague Contract or Making Payments Without Clear Milestones

A contractor’s payment schedule should support the orderly progress of the project. Homeowners should understand what each payment represents, how changes will be approved, and what must occur before final payment.

The contract should clearly address:

  • Scope of work
  • Plans and specifications
  • Contract price or pricing method
  • Allowances
  • Payment schedule
  • Anticipated schedule
  • Change-order procedures
  • Permit responsibilities
  • Cleanup and site protection
  • Insurance requirements
  • Warranty coverage
  • Dispute procedures
  • Punch-list completion
  • Final documentation
  • Applicable lien notices and releases

Avoid relying on verbal promises for important project terms.

What to do instead

Review the contract carefully and ask questions about anything unclear. For a substantial project, consider having an Oregon construction attorney review the agreement before signing.

Before final payment, confirm the agreed work and punch-list process have been completed and request the applicable project closeout documents and lien releases.

Helpful questions:
  • “How are progress payments tied to completed work?”
  • “How are change orders priced and authorized?”
  • “When is the punch list prepared and completed?”
  • “What documentation will I receive at project closeout?”
  • “How are warranty requests handled after completion?”
