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. That hesitation is common, and it’s usually well-founded: the company that just quoted the removal is also the company that gets paid if the homeowner says yes.
That’s not an accusation. Most companies that quote tree removal also perform tree removal, and pruning, and cabling, and the rest of the hands-on work that keeps a crew booked. A recommendation to remove isn’t automatically wrong because of that structure, but you should know the structure exists before you sign.
The Quote and the Assessment Are Usually the Same Visit
When a removal company walks your property, the person evaluating the tree is often the same person, or the same business, that stands to profit from the removal. There’s no second set of eyes, no separation between the diagnosis and the treatment. For a routine case, dead tree, obvious decay, clear hazard, that overlap rarely changes the outcome. For a borderline case, it can.
A large or mature tree took decades to reach its current size. A full removal and stump grinding job for a tree that size can run into the thousands of dollars. A second opinion, by comparison, is priced as a single report, typically a small fraction of that removal estimate, whether the outcome confirms the original quote or not. That’s a meaningful decision to make on a single opinion from the party who benefits financially from one particular answer.
Questions Worth Asking Before You Sign
A few questions can tell you a lot about how solid the removal recommendation actually is.
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 genuine 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, that’s useful information on its own.
What happens if I don’t remove it? A tree with a genuine structural problem usually has a documented failure risk. If nobody can describe what that risk actually is, the case for removal is weaker than it sounds.
What an Independent Assessment Adds
An independent consulting arborist writes reports and assessments only, no removal, no pruning, no 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. What separates a genuinely independent assessment is whether the firm ever performs hands-on tree work at all.
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 it’s the credential most municipalities across Southern Ontario expect to see on a report submitted for a permit application. At The Arborist Group, that certification is publicly verifiable through ISA’s directory. Sergiy Litvinov also holds ASCA membership. 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 Genuinely Is the Right Call
None of this means every removal quote deserves a second look. Some trees are unambiguous: extensive decay, a compromised root system, a documented storm-failure history. In those cases an independent assessment usually confirms what the first company said, and that confirmation still carries value: documentation with no financial stake behind it holds up if the removal is ever questioned later by a municipality, an insurer, or a neighbour.
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.
That holds whether the second opinion agrees with the first company or not. A second, independent report strengthens a permit application regardless of what it concludes, because it shows city reviewers the recommendation on file wasn’t the only opinion available on the tree.
