Before You Email
If you're reporting a calculation that looks off, include the exact inputs you used (length, width, thickness, asphalt type), the result the calculator returned, and the number you were expecting. That lets us reproduce the issue in minutes instead of hours.
For tool suggestions, tell us what problem the tool would solve for you and roughly how often you'd use it. We build tools we think our contractor and homeowner audience will actually reach for, so real-world context beats theoretical wishlists.
We don't offer project-specific paving advice, bid reviews, or contractor referrals. For those, your best bet is a licensed paving contractor in your area.
Response times: Bug reports usually get a reply within 1 business day. Tool suggestions and general questions come back inside 2 to 3 business days. If we confirm a calculation error, we push a fix the same week and post a changelog note.
