How to Compare Contractor Bids in Connecticut
Comparing bids in Connecticut has unique requirements: state registration checks, Fairfield County pricing premiums, strict permit requirements, and a DCP-recommended deposit structure that most national guides don't mention.

In Connecticut, every home improvement contractor performing more than $1,000 in annual work must be registered with the CT Department of Consumer Protection under CGS § 20-420. Registration is free to verify and takes 30 seconds at elicense.ct.gov.
This step comes before comparing prices. An unregistered contractor cannot legally enforce a home improvement contract against you in CT — but more importantly, working with one means you have no access to the CT Home Improvement Guaranty Fund if they take your money and disappear.
CT DCP reported in 2024:
265 complaints about unregistered contractors — the single largest complaint category. Verify every bidder before comparing their prices.
Check Every Bid for CT-Required Contract Elements
Under CGS § 20-429, every Connecticut home improvement contract must contain specific elements. A bid that's missing these is a red flag — and potentially unenforceable. Before comparing prices, confirm every bid includes:
Compare Pricing Against Connecticut Regional Benchmarks
Connecticut pricing varies significantly by region. Fairfield County — Greenwich, Darien, New Canaan, Westport, Stamford — typically runs 15–25% higher than the statewide average due to labor costs and the premium market. A bid that looks high for Hartford may be perfectly normal for New Canaan.
| Project Type | CT Statewide | Fairfield County | Red Flag Below |
|---|---|---|---|
| Composite deck (installed) | $40–$60/sqft | $55–$85/sqft | $30/sqft |
| PVC deck (AZEK, TimberTech) | $50–$70/sqft | $65–$90/sqft | $40/sqft |
| Pressure-treated deck | $25–$35/sqft | $32–$45/sqft | $18/sqft |
| Roofing (architectural shingle) | $9–$13/sqft | $10–$14/sqft | $6/sqft |
| Kitchen remodel (mid-range) | $75–$150/sqft | $100–$200/sqft | $50/sqft |
| Bathroom remodel (mid-range) | $400–$700/sqft | $500–$900/sqft | $250/sqft |
Benchmarks based on contractor data for Fairfield County CT including Greenwich, Darien, New Canaan, Westport, Stamford, and Norwalk. Updated Q1 2026. Very low bids often exclude permits, disposal, or use inferior materials — always ask what's included.
Evaluate the Deposit and Payment Structure
Connecticut has no legal deposit cap, but the CT DCP explicitly recommends no more than one-third (33%) upfront. When comparing bids, the payment structure is as important as the total price. Here's how to score it:
10–25% deposit, milestone payments, 10% holdback
Contractor absorbs risk proportionally. Payment tracks actual progress. Final holdback preserves your leverage.
33% deposit, 33% at start, 33% on completion
Meets DCP recommendation. Simple structure. No holdback is a minor weakness — negotiate one.
50% deposit, 50% on completion
Above DCP recommendation. Get written justification for the higher deposit. Push for milestone-based.
60%+ before work begins
Get a second opinion. Request itemized justification. Large upfront deposits are the leading pattern in CT contractor complaints.
100% upfront required
Do not pay. This is not a legitimate payment structure for any residential contractor.
Confirm Permits Are Included in Every Bid
Connecticut requires building permits for virtually all structural work — decks, additions, roofing over a certain scope, major kitchen and bathroom remodels. Permit fees in Connecticut typically run $150–$500 per municipality, depending on project scope.
A bid that excludes permit costs will come in artificially low. When comparing bids, ask each contractor to confirm:
Who pulls the permit — the contractor or the homeowner? (Should always be the contractor)
Is the permit fee included in the bid price or billed separately?
Who is responsible for scheduling inspections?
What happens if the permit reveals code issues that require additional work?
A bid that says “permit not included” isn't automatically disqualifying — but you need a written estimate of what permits will cost, and confirmation the contractor will pull them. Homeowner-pulled permits on contractor work are a red flag.
The Connecticut Bid Comparison Scorecard
Use this framework to score each bid you receive on a 1–10 scale. The highest-priced bid is often not the best, and the lowest-priced bid is almost never the safest.
| Criteria | Weight | What to Look For |
|---|---|---|
| CT DCP Registration | Pass/Fail | Must be registered at elicense.ct.gov. Fail = disqualified. |
| Price vs. CT benchmarks | 25% | Within 15% of regional benchmarks. Very low = missing scope or inferior materials. |
| Scope specificity | 20% | Specific materials (brand, product line), dimensions, code compliance language. |
| Payment structure | 20% | 33% or less upfront, milestone-based, 10% holdback. |
| Permits included | 15% | Permit fee quoted, contractor pulls permits, inspection schedule noted. |
| Timeline clarity | 10% | Specific start and end dates as required by CGS § 20-429. |
| References / CT portfolio | 10% | Similar projects in CT preferred. Local references verifiable. |
