Tight timelines

Need a Phase I ESA on a tight timeline?

Commercial property transactions and financing deadlines do not always allow for lengthy delays. Remsol provides clear, lender-ready Phase I Environmental Site Assessments for properties across Toronto and Ontario, with a typical turnaround of 5–7 business days.

If your acquisition, refinancing, or development project is operating on a tight schedule, contact our team as early as possible. We will confirm the scope, records availability, site access requirements, and the earliest achievable delivery date before work begins. Where subsurface investigation is required, we can continue directly into a Phase II ESA, and we can pair the assessment with a building and property condition assessment as part of coordinated environmental due diligence.
