10 Questions to Ask Before Hiring ANY Fence Contractor

Hiring a fence contractor is a bigger decision than it might seem at first. You're trusting someone with your property, your timeline, and a project that's going to be part of your home for a long time. It makes sense to take your time and ask the right questions.

Most contractors are professionals who take pride in their work. A few good questions upfront help you find them faster and feel confident about who you're hiring. These 10 questions are a great place to start, not to catch anyone out, but to have the kind of honest conversation that leads to a great fence installation.

‍

Quick Answer

Before hiring any fence contractor, ask about post depth, concrete specs, post material by fence type, warranty coverage, gate post sizing, wood species consistency, picket thickness, property line verification, issue resolution, and references. The answers will tell you whether a contractor understands the full scope of the job, not just the surface-level stuff.

‍

How Deep Will You Set My Fence Posts?

Post depth is one of the most important specs in any fence installation, and a knowledgeable contractor will know the answer before you finish the question. The general rule is posts go down at least one-third of your fence height, plus enough to clear the local frost line.

For a 4-foot fence in an area with a 32-inch frost line, that means 7-foot posts buried 36 inches deep. A contractor suggesting shorter posts for that same fence is leaving you with posts that are too shallow to hold up over time.

The best contractors also ask about your soil type before they quote. Sandy soil and clay behave differently underground, and depth requirements can shift accordingly.

‍

Will You Set Every Post in Concrete?

Some contractors only set corner and gate posts in concrete, leaving line posts in packed dirt. It's a common shortcut, and it shows up years later in leaning sections and wobbly panels.

A proper fence installation uses concrete for every post. Here's what that looks like in practice:

• Holes three times wider than your post
• Quick-setting concrete with a water-shedding mound on top
• Concrete stops a few inches below ground level
• Dirt backfill on top to prevent frost from gripping the concrete directly

A good contractor will walk you through their concrete process without much prompting. If that conversation never comes up, it's a good question to raise.

‍

What Type of Posts Do You Use for Different Fence Styles?

Post material depends on fence type, and a good contractor will be specific about what they use and why.

For wood fences, pressure-treated posts rated UC4B or higher are standard for ground contact. Cedar is a great material for above-ground components, but it degrades faster underground where moisture is constant.

Vinyl fences typically come with vinyl posts, but quality installations reinforce gate and corner posts with steel inserts or wood cores. Hollow vinyl posts on their own aren't built to handle the extra stress those positions carry.

Aluminum fences need aluminum posts. Mixing metals creates corrosion issues over time, which is why good contractors keep materials consistent throughout the job.

‍

What Does Your Installation Warranty Cover?

A fence contractor warranty and a manufacturer's material warranty are two different things, and it's reasonable to ask about both upfront.

A good installation warranty typically covers:

• Labor and materials
• Subcontractor work
• Building code compliance
• At least one year of coverage

Material warranties can run 10 to 30 years depending on what you're buying. But a material warranty only covers the material itself. If the installation is what caused the problem, that's where your contractor's warranty comes in. Knowing both protects you either way.

A contractor who stands behind their work will put the warranty terms in writing and be reachable after the job is done. That's a good sign on both counts.

‍

What Size Posts Will You Use for My Gates?

Gates carry more stress than any other part of a fence. Every time one opens and closes, the hinges and posts absorb that movement. Getting the post size right from the start is what keeps gates swinging cleanly years down the road.

Here's what proper gate post sizing looks like:

• 5 to 6-foot gates: minimum 6x6 posts
• Gates 8 feet and wider: 8x8 posts
• Gate posts set deeper than line posts to handle the extra load
• Vinyl gate posts reinforced with steel stiffeners

A contractor who knows gate hardware will also bring up anti-sag cables and heavy-duty hinges unprompted. That's a good sign they've installed enough gates to know where problems start.

‍

Do You Mix Different Types of Wood in the Same Fence?

It's natural to ask whether different wood species can be used together in the same fence. Cedar pickets with pressure-treated rails, for example, is a common combination. The challenge is that the two materials weather differently. Cedar goes silver-gray over time while pressure-treated lumber turns brown-gray, which can create an uneven look that's difficult to correct with stain.

There's a structural consideration too. Different wood species expand and contract at different rates and respond to moisture differently. Over time that movement stresses joints and fasteners along the fence line.

A knowledgeable contractor will explain their wood selection upfront and be consistent with species across the visible components of your fence. If mixing materials comes up, it's a good question to ask about.

‍

What Thickness Pickets Do You Recommend?

Picket thickness is one of those specs that doesn't come up in most contractor conversations, but it's a good one to ask about. The difference between standard 5/8-inch pickets and premium 3/4-inch pickets is small on paper but noticeable over time. Thicker pickets hold up better against warping, cupping, and wind load, especially in yards with a lot of sun exposure or open space.

A knowledgeable contractor will be able to explain which option makes sense for your specific yard conditions and why. That conversation is a good indicator of how they approach the job overall.

‍

How Will You Verify Property Lines?

Property lines are the homeowner's responsibility to verify, but a good contractor will help you navigate the process. Before installation starts, knowing exactly where your line sits protects you from setback violations, neighbor disputes, and having to move a fence after it's already in the ground.

If you haven't had a recent survey done, it's a good idea to bring that up during the consultation. Many contractors have working relationships with local surveyors and can point you in the right direction. At minimum, your contractor should be setting the fence a few inches inside the line rather than guessing at the boundary.

‍

What's Your Process for Handling Issues?

No project is completely without surprises. A contractor's availability after the job is done matters as much as their work during it.

The simplest thing to ask is how to reach them if something comes up. A contractor who stands behind their work will typically:

• Give you a direct contact number
• Respond to concerns within a day or two
• Put their follow-up process in writing alongside the warranty

One who's hard to pin down before the job is signed is likely to be harder to reach after. Pay attention to how quickly they respond during the quoting process. That's usually a reliable preview of what post-installation support looks like.

‍

Can You Provide Recent References?

Asking for references is completely reasonable, and most contractors expect it. The most useful references come from recent projects similar to yours in fence type and yard conditions. A neighbor who had the same material installed on a comparable lot is more helpful than a generic testimonial.

When you follow up with references, a few good things to ask about:

• How closely did the final project match what was quoted
• Whether the timeline held up
• How the contractor communicated when something unexpected came up
• Whether they'd hire them again

A contractor who's done good work is usually happy to connect you with past customers. If references aren't offered and the request gets deflected, that's something to pay attention to.

What Fence Boys Recommends for Columbus Homeowners

These questions apply to any fence contractor, anywhere. But a few of them carry extra weight in Columbus specifically. Post depth matters more here than in warmer climates because Ohio winters put real pressure on anything that's not set deep enough. Wood species consistency matters too. Ohio humidity accelerates the weathering difference between cedar and pressure-treated lumber.

When you sit down with any contractor, bring this list. A contractor who knows their craft won't hesitate on a single one. At Fence Boys, these are the kinds of conversations we welcome before the first estimate is signed.

Armed with Knowledge: Your Next Steps

These questions aren't about catching anyone out. They're about having the kind of informed conversation that leads to a fence you'll be happy with for a long time.

A contractor who knows their craft will welcome every one of them. At Fence Boys, we're always glad to walk through the details — post depth, concrete specs, materials, property lines — before anything gets signed. That transparency is part of how we work.
