Say a removal company walks a property, quotes a large maple for takedown, and leaves a written estimate on the counter. A homeowner sits on that quote for a few days, uneasy, before deciding to call a second arborist for another look. The company that quoted the removal is the company that gets paid if the homeowner says yes.
Most companies that quote tree removal also do the removal, plus pruning, cabling and the other hands-on work that keeps a crew booked. That does not make a removal recommendation wrong. Know how the company is paid before you sign.
The Removal Company Assesses Its Own Job
When a removal company walks your property, the business that evaluates the tree is the business that profits from the removal. Nobody independent checks the diagnosis. For a dead tree, obvious decay or a clear hazard, that overlap rarely changes the outcome. For a borderline case it can.
A full removal and stump grinding job for a large or mature tree can run into the thousands of dollars. A second opinion costs one report, a small fraction of that removal estimate, whatever the outcome.
Ask These Questions Before You Sign
What specifically is wrong with the tree? Ask for the diagnosis in plain terms: is it a species-level decline, a structural defect, root damage, a disease, storm history? A vague answer like “it’s not looking great” is worth pressing on.
Is this a hazard, or a preference? Some removals are driven by risk. Others are driven by leaf litter, shade over a garden bed, or a tree that’s simply in the way of a landscaping plan. Both are valid reasons to remove a tree, but they call for a different level of scrutiny before you sign off on either one.
Would the diagnosis hold up in a written report? A verbal opinion during a sales visit and a signed arborist report are not the same document. If the company won’t put its reasoning in writing, treat that as a warning.
What happens if I don’t remove it? A tree with a structural problem has a failure risk someone can describe. If nobody can describe it, the case for removal is weak.
What an Independent Assessment Adds
An independent consulting arborist writes reports and assessments only and does no removal, pruning or cabling. Income comes from the report itself rather than from whatever work follows it, which removes the incentive to lean toward one answer over the other.
ISA certification confirms technical competence, but it doesn’t by itself confirm independence. A certified arborist can still work for a company that profits when the tree comes down. An assessment is independent only if the firm does no hands-on tree work.
Ontario has no provincial licence for arborists, so there’s no government credential to check the way there would be for an electrician or plumber. ISA certification fills that gap as the industry’s recognized standard, and Toronto, Mississauga, Brampton, Markham and Richmond Hill all name ISA certification as an accepted credential for the author of a permit report. At The Arborist Group, that certification is publicly verifiable through ISA’s directory. Details are on our credentials page.
A second opinion carries no discount for being a follow-up look, and no markup either. It’s priced the same as a standalone report. For current pricing, see our arborist report cost guide. If you’re not sure whether your situation calls for a full removal report or a formal risk assessment, our self-triage guide walks through the signs and which document fits.
When Removal Is the Right Call
Some removal quotes need no second look. Extensive decay, a compromised root system or a documented storm failure makes the case. An independent assessment then confirms the first company’s call, and a report with no financial stake behind it holds up if a municipality, an insurer or a neighbour questions the removal later.
Our full breakdown of when a second opinion changes the outcome covers contested permits, heritage or specially designated trees, and cases where the tree’s condition is uncertain.
