How to Compare Contractor Bids in 2026 (Without Getting Ripped Off)

How Many Bids Should I Get Before Hiring a Contractor in 2026?

Get three bids. Minimum. Not two. Not one. Three.

As a licensed GC who has completed hundreds of remodels, I can tell you that roughly 40% of homeowners I talk to only got one or two estimates before signing a contract. That is how you end up overpaying by $15,000 to $30,000 on a kitchen remodel.

Here is why three is the magic number. With two bids, you have no baseline. One could be inflated, one could be missing half the scope, and you have no way to tell which is which. Three bids give you a pattern. You start to see what a fair price looks like for your specific project.

Based on 2026 construction cost data, a mid-range kitchen remodel in the Bay Area runs $75,000 to $150,000. That is a massive range. Without multiple bids, you are guessing where your project falls. Homeowners who collect three or more estimates typically save 10-15% compared to those who go with the first contractor they meet.

And here is the thing most people miss. Getting bids is also a vetting process. How fast does the contractor respond? Do they show up on time to the walkthrough? Is the estimate detailed or a single number on a napkin? If your general contractor takes 48+ hours to return a text during the bidding phase, that is a red flag for how communication will go during construction.

Opsite recently launched a free set of homeowner tools at homeowners.useopsite.com/compare that let you upload 2 to 4 contractor estimates and get an instant side-by-side comparison with CSLB verification and trust scores. But even without a tool, the principle is the same. Three bids. Always.

What Should a Contractor's Estimate Actually Include?

A real estimate includes itemized line items, a written scope of work, payment terms, a project timeline, warranty details, and the contractor's CSLB license number. If any of those are missing, that is not an estimate. That is a guess.

"As a contractor, I can tell you that 80% of disputes I see come from vague estimates and mismatched expectations. When a bid just says 'kitchen remodel - $85,000' with no line items, you have zero protection when the contractor adds $12,000 in change orders for unforeseen conditions."

From working with homeowners on projects ranging from $50K to $2M+, I have seen the same pattern over and over. The most detailed estimate is almost always the most honest one. The contractor who takes time to break things down is the contractor who actually measured your space and priced it properly.

Here is what you should see broken down: demolition and haul-off, rough plumbing and electrical, framing and drywall, cabinets (with brand and style), countertops (with material type), flooring (with material and square footage), fixtures, appliances if included, paint (brand and number of coats), permits and inspections, and final cleanup.

How Do I Spot a Low Bid That Will Cost Me More Later?

If the lowest bid is 30% or more below the others, that is not a deal. That is a contractor who will hit you with change orders later.

In my experience building homes across Silicon Valley since 2017, I have seen hundreds of these "too good to be true" bids. They fall into three categories.

The scope skipper. They left out entire categories. No demolition costs. No permits. No cleanup. The total looks low because they are not pricing the whole job. You will pay for it later as change orders, typically $25,000 to $40,000 more than the original bid on a mid-size remodel.

The material downgrader. Their bid says "countertops" but does not specify the material. You are expecting quartz at $80 per square foot. They are pricing laminate at $25 per square foot. The $8,000 to $15,000 difference shows up when you are mid-project and already committed.

The front-loader. They want 50% upfront. In California, that violates Business and Professions Code Section 7159.5, which caps deposits at $1,000 or 10% of the contract price, whichever is less. A contractor who ignores this law will ignore other things too.

"As a contractor, I can tell you the lowest bid almost always costs more in the end. The math just does not work. If three contractors priced the same job and one is $30,000 cheaper, something is missing from that estimate. Period."

Opsite's free deposit calculator checks whether your contractor's requested deposit complies with California law and generates a response you can send if it does not.

What Is a Contractor Trust Score and Why Does It Matter?

A trust score is a 0 to 100 rating based on verifiable public data about a contractor. It checks six things: license status, workers compensation insurance, contractor bond, years in business, disciplinary history, and insurance compliance.

This matters because a good estimate from an unlicensed or under-insured contractor is worthless. According to CSLB complaint data, homeowners file over 20,000 complaints per year against California contractors. Many of those could have been avoided by checking public records before signing anything.

Opsite's free license checker calculates this automatically. Enter a license number and get the full breakdown in seconds. The estimate comparison tool runs this for every contractor in your bid set.

But even without a tool, you can check the basics yourself. Go to cslb.ca.gov right now and look up their license number. Takes 30 seconds. Verify the license is active, the classification matches your project type (B for general contractor, C-specialties for specific trades), and there are no disciplinary actions on record.

"As a contractor, I can tell you the single biggest protection you have is 30 seconds on cslb.ca.gov. A contractor scoring below 60 out of 100 is a real risk. Between 60 and 80, proceed with caution and ask questions. Above 80, their basics are covered."

How Do I Compare Line Items Across Different Bids?

Go line by line. Category by category. The total price means nothing if you do not understand what is included in each bid.

Open all three estimates side by side. Create a simple grid with categories down the left and contractor names across the top. For each category, note the price and what is specifically included.

Based on 2026 construction cost data, here are typical line item ranges for a Bay Area kitchen remodel and the questions you should ask:

• Demolition: $3,000 to $8,000. Does it include haul-off and dump fees?
• Plumbing rough-in: $5,000 to $12,000. How many fixture relocations are included?
• Electrical: $4,000 to $10,000. Is a panel upgrade included or extra?
• Cabinets: $10,000 to $40,000. Stock, semi-custom, or custom? What brand?
• Countertops: $4,000 to $15,000. What material? Edge profile? Thickness?
• Flooring: $3,000 to $12,000. Material type and exact square footage?

When one contractor is $7,000 higher on electrical, do not assume they are overcharging. They might be the only one who included the panel upgrade you actually need. That is a scope gap, not a price difference.

Based on typical project data from Bay Area contractors, scope gaps are the number one reason projects blow budgets. A missing $6,000 electrical panel upgrade or $4,000 in permit fees does not disappear. It just shows up later as a change order when you have no negotiating power.

Opsite's comparison tool flags these scope gaps automatically. It parses your uploaded estimates, normalizes the categories, and shows you exactly what each contractor includes or excludes. The Pro Report ($49) goes deeper with material quality comparisons and negotiation talking points specific to each bid.

What Should I Verify Before Signing Any Contractor Agreement?

Before you sign anything, verify five things: active CSLB license, current workers compensation insurance, contractor bond, legal deposit amount, and a written warranty. This is non-negotiable.

License. Go to cslb.ca.gov and confirm the license is active and matches the contractor's name and business entity. The classification should match your project type.

Workers compensation. If the contractor has employees or uses subcontractors, they need workers comp insurance. If a worker gets hurt on your property and the contractor has no coverage, you could be liable. Ask for a certificate of insurance naming you as additionally insured.

Bond. California requires a $25,000 contractor bond filed with the CSLB. This protects you if the contractor fails to perform. Verify it is on file and current.

Deposit. California law caps deposits at $1,000 or 10% of the contract, whichever is less. Any contractor asking for more is violating state law.

Payment schedule. Structure payments around milestones, not calendar dates. A solid draw schedule ties your payments to completed work. Here is what I recommend: $1,000 deposit at signing (the CA legal max for most projects), 20% at demolition complete, 25% at rough inspection passed, 25% at finish installation, then hold the final 10-20% as retainage until the punch list is 100% done.

Request lien waivers from your general contractor with each progress payment. A lien waiver confirms the contractor and their subcontractors have been paid for completed work. Without one, a subcontractor who did not get paid can file a mechanic's lien on your property - even if you already paid your GC in full.

Add 15-20% contingency to your total budget. Not 10%. Every project hits something unexpected behind the walls, under the floors, or above the ceiling. That contingency is not optional. It is the difference between a stressful project and a manageable one.

If you are a contractor looking to professionalize your estimating and project management process, Opsite's operations platform at useopsite.com/features handles everything from estimates to draw schedules to subcontractor management.

Frequently Asked Questions About Comparing Contractor Bids

How many contractor bids should I get for a remodel?

Get three bids minimum. This gives you a baseline to identify fair pricing, spot outliers, and compare scope coverage. Homeowners who collect three or more estimates typically save 10-15% compared to those who go with the first contractor they meet.

What is the average cost of a kitchen remodel in California in 2026?

Based on 2026 construction cost data, mid-range kitchen remodels in the Bay Area run $75,000 to $150,000 depending on scope, materials, and location. Factors like cabinet quality, countertop material, and whether you are moving plumbing or electrical have the biggest impact on total cost.

How do I check if my contractor is licensed in California?

Visit cslb.ca.gov and enter the contractor's license number. Verify the license is active, the business name matches, and there are no disciplinary actions. Opsite's free license checker at homeowners.useopsite.com/check does this automatically and calculates a trust score based on six verification factors.

What is the maximum deposit a contractor can legally charge in California?

California Business and Professions Code Section 7159.5 limits deposits to $1,000 or 10% of the total contract price, whichever is less. Any contractor asking for more is violating state law. This applies to home improvement contracts for projects on existing residential property.

What should I do if one contractor bid is much lower than the others?

Be cautious. If a bid is 30% or more below the others, the contractor likely left out scope items, is using lower-quality materials, or plans to make up the difference with change orders. Ask them to explain the gap line by line before assuming it is a better deal.

What is a contractor trust score?

A trust score is a 0 to 100 rating calculated from public CSLB data. It checks license status (25 points), workers compensation (15 points), bond (10 points), years in business (15 points), disciplinary history (20 points), and insurance compliance (15 points). A score above 80 means the contractor's basics are solid.

Should I always choose the cheapest contractor?

No. The cheapest bid often leads to the most expensive project due to change orders, missing scope, and material downgrades. Focus on scope completeness, material specifications, contractor trust score, and payment terms. A mid-priced bid with detailed line items and a trust score above 80 is usually the best value.

How much contingency should I add to my remodel budget?

Add 15-20% contingency to your total project budget. Not 10%. Every remodel uncovers unexpected issues behind walls, under floors, or in outdated wiring and plumbing. On a $100,000 kitchen remodel, that means setting aside $15,000 to $20,000 for surprises.
