What This Calculator Actually Does
Neighbour disputes rarely come with an obvious dollar figure attached. A damaged fence, a fallen tree, or a boundary encroachment each involve their own way of arriving at a number — a repair estimate, a replacement cost, or the value of what's actually been lost. This calculator walks through the details of your specific situation and produces a general estimate of what the dispute might be worth, so you have a starting figure before deciding how to proceed. For the fuller legal picture behind these disputes, including how responsibility is generally assessed, see neighbour disputes in Small Claims Court.
What You'll Need to Use It
- A clear description of what happened — a boundary encroachment, tree or water damage, a fence dispute, or a noise-related cost.
- Repair or replacement estimates, where the dispute involves physical damage.
- Any relevant dates, including when the damage occurred or when the issue first arose.
- Whatever documentation you already have — photos, a survey, or correspondence with your neighbour.
What Kinds of Neighbour Disputes This Covers
This tool is built around the most common categories of neighbour dispute that end up in Small Claims Court:
- Boundary and property-line encroachment — a fence, structure, or planting built over the line separating two properties.
- Tree and root damage — a fallen tree, storm damage, or roots that crack a driveway or foundation.
- Water runoff and drainage damage — grading or drainage changes on one property that cause damage to another.
- Fence disputes — disagreements over cost-sharing, placement, or responsibility for repair.
- Noise-related costs — a measurable, documented loss connected to an ongoing noise issue, rather than the general annoyance itself.
It isn't intended for criminal harassment matters, which fall outside Small Claims Court and need to be addressed through different channels entirely.
Evidence That Strengthens a Neighbour Dispute Claim
Photographs taken promptly after damage occurs are some of the most useful evidence in any neighbour dispute. For a genuine boundary disagreement specifically, a professional property survey or municipal records can resolve the underlying factual question — where the line actually runs — in a way no amount of back-and-forth between neighbours can. See neighbour disputes for a fuller look at when a survey is likely worth the added cost.
Why a Documented Approach Matters Here
Neighbour disputes carry a wrinkle most other claims don't: however the matter resolves, you're probably still going to be living next to this person afterward. A calm, documented conversation, or a clear written demand, is worth attempting before filing in almost every case — see the demand letter builder for a structured way to put one together. Beyond potentially resolving things directly, it shows you made a reasonable effort to work things out, which reflects well regardless of how the dispute ultimately proceeds.
What to Do With the Result
Once you have an estimate, weigh it against the cost and effort of pursuing a claim — see the court fee calculator for what the process itself might cost. If the number still supports moving forward, starting a claim walks through the full process from a demand letter through filing.

Frequently Asked Questions
Is this calculator free to use?
Yes — it's provided as a free informational tool, with no account or payment required.
What kinds of neighbour disputes does this cover?
Property line and encroachment disputes, damage caused by trees or water runoff, fence disputes, and noise-related costs. It isn't meant for criminal harassment matters, which fall outside Small Claims Court entirely.
Do I need photos or a survey to support a claim?
Photos are strong evidence in almost every neighbour dispute, and for a genuine boundary disagreement, a property survey or municipal records are often the most reliable way to settle the facts.
What if my municipality has a bylaw process instead?
Some neighbour issues — like a fence height or a property standards complaint — go through municipal bylaw enforcement first or instead. Check whether that applies before or alongside a Small Claims Court claim.
