Is it a good idea to replace a fence yourself?
The first question to ask is whether tackling a fence replacement solo is advisable in your particular situation. Here are some pros and cons to weigh:
| Pros | Cons |
|---|---|
| – Saves on labor costs | – Very time consuming and labor intensive |
| – Freedom to choose design/materials | – Requires familiarity with tools and building |
| – Satisfaction of DIY project | – Possible permitting requirements |
| – Flexible schedule | – Physical toll on body |
In general, replacing a fence yourself is realistic if you have decent DIY skills, time flexibility, and physical capability to take on a strenuous project. Hiring a professional is advisable for very large fence replacement jobs or if you lack the skills or time.
What’s involved in replacing a fence?
Replacing a fence from start to finish involves a number of key steps:
- Pulling out and disposing of the old fence and posts
- Preparing the area by leveling the ground
- Installing new fence posts
- Attaching brace assemblies to corner and gate posts
- Attaching rails between the fence posts
- Installing pickets, panels, or wire fencing material
- Adding decorative caps to posts
- Sealing and staining/painting the new fence
Sections of damaged fencing can be replaced, but it’s often easiest to redo the entire run. Proper disposal of old fencing materials is key.
Tools and materials
Here are some of the essential tools needed:
- Post hole digger
- Shovel
- Circular saw
- Power drill
- Level
- Hammer
- Nail gun
- Wheelbarrow
- Carpenter’s pencil
And some key materials include:
- Fence posts
- Concrete for securing posts
- Gravel or crushed rock
- Fence panels or pickets
- Rails
- Screws, bolts, nails
- Post caps
Step-by-step instructions
Here is an overview of the key steps involved in replacing an existing fence:
- Remove old fence: Use a circular saw, pry bar, and shovel to dismantle and pull out all existing fence posts, panels, rails, and materials. Dispose at a landfill.
- Clear area: Clear a 12-18 inch space on either side of the planned new fence line using a shovel and pickaxe. Remove debris and level the ground using a rake.
- Mark post holes: Measure and mark where new post holes will go using spray paint or stakes. Space holes 6-8 feet apart.
- Dig post holes: Dig holes 12-18 inches wide and 2-3 feet deep using a post hole digger or power auger.
- Set posts: Place posts in holes centered and straight. Fill bottom of hole with 6 inches of gravel for drainage.
- Brace corner posts: Install brace assembly kits on corner and gate posts per manufacturer instructions to reinforce.
- Fill holes: Mix concrete and pour dry into holes around posts. Fill 2/3 of the depth. Add water to set concrete.
- Attach rails: After concrete cures, attach horizontal rails between posts using bolts or screws.
- Hang fencing: Attach fencing material (e.g. pickets, panels, wire) to rails per product specifications.
- Cap posts: Adhere post caps on top of fence posts for decorative finish.
- Seal fence: Paint, stain or seal new fence with waterproofing product.
Estimating materials needed
To estimate materials, measure the length of your fence line and space between posts. Calculate:
- Post quantity: Divide length by spacing (e.g. 100 ft length / 8 ft between posts = 13 posts)
- Post hole concrete: Multiply ~0.5 bags of concrete x number of posts
- Rails: Length of fence line
- Pickets: Height of fence x length ÷ spacing between pickets
Add about 10% extra to account for mistakes and waste.
Difficulties and challenges
Replacing a fence solo does involve some key difficulties and strenuous work:
- Digging post holes and leveling terrain
- Mixing and pouring concrete
- Measuring and cutting rails accurately
- Working alone to maneuver heavy materials
- Installing posts straight and sturdy
- Following all safety precautions
The job also takes time – typically 3-5 full work days for a medium backyard wooden privacy fence. Frustrations and complications can arise from issues like hitting hidden pipes or wires while digging, concrete setting too quickly or slowly, warped fence panels, and having posts tilt out of alignment if soil is uneven.
Tips for avoiding difficulties
Here are some tips to make the fence replacement process easier:
- Rent a power auger for quick digging of uniform post holes
- Use braces and cleats when needed to keep posts aligned until concrete sets
- Pre-assemble fence panels where possible to minimize complexity
- Follow all manufacturer’s instructions for proper material usage
- Recruit a helper for lifting, mixing, and holding items in place
- Take breaks and drink water to avoid exhaustion in heat
Cost comparison of DIY vs professional replacement
One of the biggest allures of replacing a fence yourself is the cost savings versus hiring a professional. For a basic 6 foot tall cedar privacy fence, pricing could compare as follows:
| Cost Factor | DIY | Professional Install |
|---|---|---|
| Fence materials | $1,000 | $1,000 |
| Labor | $0 | $2,500 |
| Tool rentals | $150 | $0 |
| Total cost | $1,150 | $3,500 |
As shown, by not paying for professional fence builders, you can save $2,350 on a project of this scale by doing it yourself. Tool rental fees add minimal costs for the DIY route.
However, there are scenarios where it makes more sense to hire a pro:
- Very long or poorly accessible fence lines
- Intricate fence or gate designs
- Underground complications like large rocks
- Limited personal time available for DIY work
Regardless of whether you DIY or hire a contractor, always get multiple quotes first since pricing can vary greatly.
Permit requirements
Before starting any fence replacement project, be sure to check on permit requirements for your local jurisdiction. Typical scenarios requiring permits include:
- Fences over 6 feet tall
- Front yard fences
- Fences blocking right of way/easements
- Historic districts
There may also be restrictions on fence height, materials, distance from property lines, and finished sides facing out. Not getting proper permits can lead to fines, tear-down orders, and difficulty selling the property, so research first.
How to apply for a permit
Applying for a fence permit typically involves:
- Contacting the building/zoning department to confirm requirements
- Completing a permit application including project address, scope, materials, and estimated cost
- Providing a survey or site plan showing exact location
- Paying the permit fee (often $25-$75)
You’ll then receive an approved permit to display on-site before starting work. The local agency may later inspect the finished fence for compliance.
Is it worth it for resale value?
Will replacing an old, run-down fence boost your home’s resale value? Here are some considerations:
- Curb appeal – Fresh fencing enhances “kerb appeal” and makes a strong first impression
- Lower maintenance – Old fences can cost time/money for constant repairs
- Safety and security – Sturdy fences add privacy and protect pools
- Compliance – Updating to meet current codes can speed sales
- Costs – DIY is affordable, but upgrades too costly may not see full return
In general, a fence update is unlikely to highly impact resale dollar value, but will make the property far more attractive and marketable to buyers.
When is it worth hiring a pro?
Cases when hiring a professional fence company pays off in added resale value:
- Historic homes requiring period-appropriate fences
- Properties with extensive, complex fencing
- Making significant upgrades in materials (e.g. wood to iron)
- Incorporating unique designs like automatic gates
- Fixing compliance issues on permits/codes
For more customized, intricate projects, a professionally installed fence can better boost home resale dollars versus DIY.
Conclusion
Replacing an entire fence solo is a major undertaking, but can be feasible and affordable with proper planning. From costs to permits and techniques, consider all key factors involved before embarking. While challenging, a new fence ultimately adds function and beauty to outdoor spaces for years of enjoyment and potentially higher resale value.
