“Request an Estimate” is for an early-stage inquiry — you're still exploring options and want to talk through scope, budget, and timeline before committing to details. “Post a Project” is for a defined, ready-to-scope project — you already have an address, budget range, timeline, and often drawings or photos — and it goes straight to our estimating team for a formal quote.
Start with “Request an Estimate.” It's the lighter-weight option — just tell us the basics and we'll follow up to help scope things out. You can always submit a full “Post a Project” once you have more details, drawings, or documents ready.
No. Neither option requires an account or login — fill out the form and our team follows up directly by phone or email.
No — “Post a Project” and “Request an Estimate” are for clients and property owners with construction work to be done. Subcontractor and subtrade interest is handled through our Careers & Subcontractor Network page instead.
For a “Post a Project” submission, an estimator will contact you within 2 business days. For a “Request an Estimate” submission, our team follows up shortly after — both go directly to our estimating team, not a call centre.
Tell us the scope and we'll get back to you with next steps.
