Stratford in public records | Record | What it shows | Official source and period | |---|---|---| | People per square mile | 3,084 | [Calculated from U.S. Census Bureau 2025 estimates and Gazetteer land area](https://www.census.gov/geographies/reference-files/time-series/geo/gazetteer-files.html) 2025 | | Land area | 17.5 sq mi | [U.S. Census Bureau, 2025 Gazetteer files](https://www.census.gov/geographies/reference-files/time-series/geo/gazetteer-files.html) 2025 | | Stratford residents | 53,908 | [U.S. Census Bureau, Vintage 2025 population estimates (sub-est2025)](https://www.census.gov/data/tables/time-series/demo/popest/2020s-total-cities-and-towns.html) July 1, 2025 | | Population change since 2020 | +2.9% from 52,383 (April 2020 base) | [U.S. Census Bureau, Vintage 2025 population estimates (sub-est2025)](https://www.census.gov/data/tables/time-series/demo/popest/2020s-total-cities-and-towns.html) 2020–2025 | Figures tagged “Sample figure” show what our live data feed will fill in from that source; they are not real counts. We never print license numbers: look them up on the official portal. ## Hiring hvac contractors in Stratford: what to check yourself 1. **Ask for the license number and look it up.** The license should be in the company's or owner's name, not a third party who lends it. 2. **Get the insurance certificate sent from the insurer to you.** Ask for liability and, if they have employees, workers' compensation. 3. **Make sure the contractor pulls any permit.** If you are asked to pull it as the owner, treat that as a red flag. 4. **Tie payments to finished stages** rather than paying most of the price up front. 5. **Get the scope, price and warranty in writing** before work starts.
