"How do you verify the property line before installation?"

Why it matters: Building a fence on or over the property line is one of the most expensive fencing mistakes. It can require removing and rebuilding the fence and create neighbor disputes that end up in court.

"Is a permit required for this fence?"

Why it matters: Most jurisdictions require permits for fences over a certain height (typically 4 feet for front yard, 6 feet for backyard). HOA rules may add additional restrictions.

"How deep are the posts set, and what is the concrete spec?"

Why it matters: Post depth is critical for fence stability and frost resistance. In frost-prone climates, posts must go below the frost line (which can be 30-50+ inches in northern states).

"Do you use solid concrete around the post or a gravel base with concrete top?"

Why it matters: Solid concrete extends down to the bottom of the hole and is the stronger option for most situations. A gravel base with concrete collar allows drainage but can allow post movement over time.

"How do you prevent wood post rot?"

Why it matters: For wood fences, pressure-treated posts (rated for ground contact, typically .40 or .

"What are the post caps, and are they included?"

Why it matters: Post caps prevent water from sitting on the top end grain of wood posts. An uncapped post end is the primary place where rot begins in a wood fence.

"Is removal and disposal of the existing fence included?"

Why it matters: Old fence removal is labor and disposal cost that is often extra. Get this priced upfront.

"How do you handle gates? What hardware are you using?"

Why it matters: Gates fail faster than any other part of a fence. Cheap hinges sag.

"How do you ensure the fence line is level and straight?"

Why it matters: A wavy or unlevel fence line is the most visible quality indicator on a finished fence. A good contractor uses string line, laser level, or both to establish the fence line before setting any posts.

"What is your warranty on labor?"

Why it matters: Fence post settling, leaning panels, and gate problems are the most common warranty callbacks. Know what the contractor will fix and for how long.

"Do I need HOA approval, and have you worked in this neighborhood before?"

Why it matters: HOA rules frequently restrict fence height, material, color, and style. A fence installed without HOA approval can require expensive removal and rebuilding.

"What is the payment schedule?"

Why it matters: Materials for fencing are often ordered and delivered before installation. A deposit at signing, materials payment on delivery, and balance on satisfactory completion is standard.
