The Hamilton, Ontario general contractors list has 92 businesses, 48 of them with a business email. Each record has the business name, phone, address, website and Google rating. One-time $9 USD — download Excel and CSV right after checkout, no subscription.
Five rows from the full 92-row dataset, sorted by rating & review count. The full file has one row per business with 16 columns: business name, email, email type (business or personal), phone, street address (with postal code), city, state/province, country, Google rating, review count, website, email quality, audit date, and any other emails and phones we found for the business with where we found them. The CSV adds email_2, email_3… where a business has more than one address. Service-area businesses (mobile mechanics, handymen, cleaners) deliberately don’t list an address on Google, so that column is blank for about 2% of rows.

Find a verified general contractor near you. Get directions or visit their website directly — sorted by Google rating.
Start with the rating — look for a general contractor holding 4.5 stars or higher with a healthy number of recent reviews, which signals consistent, current service. Confirm they're properly licensed and insured for the work you need, and read a few reviews to see how they handle problems, not just praise. The listings below are sorted by Google rating to make this easier.
Pricing varies widely by the scope of the job, materials, and how urgent the work is, so there's no single rate. The most reliable approach is to contact two or three general contractors directly for a quote on your specific situation.
