What to Know Before Hiring a Home Contractor
Hiring the right contractor can prevent delays, unexpected costs, poor workmanship, and disputes. Before signing anything or paying a deposit, confirm that the contractor is qualified and that the project details are clearly documented.
Contractor licensing, deposit limits, lien rules, permits, and cancellation rights vary by state and locality. Check with your state licensing agency, local building department, and consumer protection office for requirements that apply where you live.
Define the Project Before Requesting Bids
Write down what you want completed, which materials or finishes you expect, and any work that should be excluded. Include photographs, measurements, drawings, or product examples when helpful.
Give the same information to every contractor. This makes estimates easier to compare and reduces the chance that one bid appears cheaper because it leaves out important work.
For projects involving hidden conditions, such as water damage or outdated wiring, ask how unexpected problems will be documented and priced.
Get More Than One Written Estimate
Obtain several written estimates when practical. Each should identify the work, materials, estimated schedule, and price. Ask questions when there is a large difference between bids.
The lowest estimate is not automatically the best choice. It may exclude permits, disposal, preparation, repairs, or finish work included by another contractor. An unusually low price can also indicate underestimated labor, lower-quality materials, or an attempt to secure the project before adding charges later.
The Federal Trade Commission recommends getting multiple estimates and comparing what each contractor promises to provide.
Verify the Contractor Independently
Ask for the contractor’s complete business name, physical address, telephone number, and license number. Verify the license directly through the appropriate state or local licensing agency rather than relying on a card, screenshot, or website badge.
Check that:
The license is active.
The name on the license matches the person or business you are hiring.
The license covers the type of work being performed.
Any required bond is current.
The licensing agency does not list unresolved disciplinary action.
Not every jurisdiction licenses every type of contractor. Where licensing is not required, business registration, insurance, references, permit history, and a detailed contract become especially important.
Check Insurance Coverage
Ask for proof of general liability insurance and workers’ compensation coverage where applicable. A business license and an insurance policy are not the same thing.
Consider contacting the insurer or agent listed on the certificate to confirm that the policy is current. Ask whether subcontractors will be used and how their insurance and qualifications are verified.
If an uninsured worker is injured or the contractor damages neighboring property, the resulting dispute can be far more expensive than the original project.
Review Similar Work and References
Ask for recent references from projects similar in size and type to yours. Useful questions include:
Was the final price reasonably close to the agreed price?
Did the contractor communicate about delays and changes?
Was the property protected and cleaned properly?
Were problems corrected?
Would the customer hire the contractor again?
Photographs are helpful, but they do not prove who performed the work. When possible, review completed projects, public permit records, or inspection histories. Online reviews can reveal patterns, but individual reviews should not replace license and reference checks.
Ask Who Will Perform the Work
The person preparing the estimate may not be the person supervising the project. Ask who will be present each day, who has authority to make decisions, and how often the contractor will visit.
Find out which portions will be completed by subcontractors. Plumbing, electrical, HVAC, roofing, and structural work may require separately licensed trades. The contract should identify responsibility for hiring, supervising, and paying them.
Confirm the Permit Process
Contact the local building department if you are unsure whether permits or inspections are required. Do not rely only on a contractor’s statement that a permit is unnecessary.
The written agreement should explain who will obtain permits, pay the fees, arrange inspections, and correct rejected work. Be cautious if a contractor asks you to obtain a permit intended for work performed directly by a property owner. Doing so may shift important responsibilities to you.
Before making the final payment, confirm that required inspections are complete and that the permit has been properly closed.
Require a Detailed Written Contract
A contract should identify the parties, contractor license information, property address, total price, payment schedule, and expected start and completion dates.
It should also describe:
The complete scope of work
Materials, brands, model numbers, colors, and quantities
Preparation, cleanup, and debris removal
Protection for landscaping, floors, furniture, and neighboring property
Permit and inspection responsibilities
Procedures for delays and unexpected conditions
Labor and material warranties
How changes and disputes will be handled
Include verbal promises in the written agreement. Do not sign a contract with blank spaces, unclear allowances, or missing attachments. Keep a signed copy before work begins.
Changes should be documented through written change orders stating the revised work, price, and schedule. Both parties should approve the change before the additional work starts.
Use a Payment Schedule Based on Progress
Avoid paying the full price upfront. Some states limit the deposit a home improvement contractor may collect, so check local law before paying.
Later payments should correspond to clearly defined stages of completed work rather than arbitrary dates. Use a traceable payment method and keep invoices and receipts.
Before releasing final payment, check that:
The agreed work is complete.
Required inspections have passed.
Remaining defects are listed and corrected.
Warranties and product information have been provided.
The site has been cleaned.
Required lien releases have been received.
Understand Mechanics Lien Risk
Depending on state law, subcontractors, laborers, and material suppliers may be able to place a mechanics lien on the property if they are not paid—even when the homeowner already paid the general contractor.
Ask for a list of major subcontractors and suppliers. Learn which preliminary notices and lien waiver forms are used in your state. When appropriate, collect conditional waivers with progress payments and final waivers after payments have cleared.
Lien deadlines, notices, and waiver language are highly state-specific. For a large project, consider having a local construction attorney review the payment and lien-release process.
Be Careful With Contractor Financing
Treat the construction agreement and financing documents as separate decisions. Compare loan terms independently instead of accepting contractor-arranged financing without reviewing alternatives.
Never sign blank forms or documents you do not understand. Confirm the interest rate, fees, total repayment amount, monthly payment, and whether the loan is secured by your home. A lender may pay the contractor before the work is satisfactorily completed.
Recognize Common Warning Signs
Use caution when a contractor:
Arrives unexpectedly and claims to have leftover materials
Pressures you to decide immediately
Demands full payment or cash in advance
Offers a price that is far below other estimates without explanation
Refuses to provide a written contract
Cannot provide verifiable license or insurance information
Wants you to obtain permits that the contractor would normally handle
Encourages you to sign over an insurance check
Pushes financing through a particular lender
Has no verifiable business address or recent local references
These warning signs are especially important after storms and other disasters, when traveling contractors may target damaged neighborhoods.
Do Not Assume You Can Cancel Any Contract Within Three Days
The FTC’s Cooling-Off Rule allows consumers to cancel certain sales made at their home, workplace, or a seller’s temporary location within three business days. However, the rule has several exceptions and does not cover every home repair or remodeling agreement.
State law may provide additional cancellation rights. Read the cancellation section before signing and keep any required cancellation forms.
Taking time to verify the contractor, compare complete bids, and document the project is usually easier than trying to correct a bad hiring decision after work begins.
This article provides general consumer information and is not individualized legal advice. Contractor licensing, deposits, permits, liens, insurance requirements, and cancellation rights vary by jurisdiction.
