BEST WAY TO EXTEND EXISTING FENCES

When the time comes to expand a fence, some planning and preparation will ensure your new addition blends seamlessly with the existing barrier. Materials, installation methods, and styling for the extension depend on your current fence type. Here are some tips for properly extending the most common backyard fence varieties.

Extending a Wood Fence

Wood is a classic fencing material that comes in various budget-friendly styles. Follow this advice for successfully elongating a wood fence:

  • Use pressure-treated pine posts for durability and resistance to rot and insects. Look for rated, deep-buried posts.
  • Choose weather-resistant wood panels like cedar or redwood that match existing boards.
  • Allow for expansion by leaving small gaps between fence boards.
  • Alternate new and old boards sectionally for a cohesive look.
  • Match the height and post spacing intervals of the original wood fence.
  • Paint or stain new boards to match old ones or refresh the entire fence.
  • Recheck wood fence extensions annually and clean, sand, or seal boards as needed.

Extending a Chain Link Fence

The woven wire design of chain link fences makes lengthening them simple:

  • Use galvanized steel pipe for posts and 1 3/8” diameter top rails for strength.
  • Match the height and mesh gauge of the existing chain link fencing.
  • Use metal post caps atop posts and proper top rail fasteners.
  • Weave new fencing into old with wire ties or compression clamps for a smooth transition.
  • Install a terminal post at the end of the extension to properly tension the wire.
  • For added privacy, add matching vinyl slats that slide into the chain link mesh.

Extending a Metal or Aluminum Fence

Metal fences are sturdy, durable choices. Follow these tips when expanding an ornamental iron, steel, or aluminum fence:

  • Match the height, post style, and panel design of the existing fence.
  • Use metal post anchors for proper support and preventing rust if attaching to concrete.
  • Look for electrostatically applied powder coated metal in a matching color.
  • For welded wire metal fencing, use tension bars and stretcher bars.
  • Leave room between fence panels for minor temperature-related movement.
  • Blend old and new panels together for a cohesive linear look.

Extending a PVC or Vinyl Fence

For low-maintenance longevity, vinyl makes a great fencing choice. Here’s how to expand a PVC fence:

  • Look for matching extruded vinyl panels and posts to resist impact, weathering, and fading.
  • Include aluminum or galvanized steel reinforcement inside hollow vinyl posts.
  • Set posts in concrete for maximum stability.
  • Alternate new and old fence sections for a seamless look.
  • Make sure fence heights match when transitioning between sloped areas.
  • Allow room for expansion and contraction between fence panels.

Extending an Ornamental Fence

Decorative fences like wrought iron, copper, or aluminum visually enhance properties. Follow these tips for extending ornamental fences:

  • Select designs and materials that closely match the existing ornamental fence style.
  • Use detailed, durable components that provide aesthetic continuity with old fencing.
  • Anchor and mount decoratively molded post tops, finials, and caps to specifications.
  • Space ornamental posts, rails, and pickets precisely based on the established fence.
  • Allow room between fence sections and posts for minor thermal expansion and contraction.
  • Blend new and existing ornamental fence sections for a harmonious expanded barrier.

Properly extending any fence takes careful measuring, durable materials suited to each fence type, proper installation, and blending new with old. Follow the specific recommendations for your existing fence variety. Investing a little extra effort yields beautiful, blended backyard fencing expansions.
