The Williamsburg Fiberglass pergola is the strongest pergola kit on the market, it will provide you a lifetime of enjoyment.

The Williamsburg is similar to our Potomac vinyl pergola. It has a double 2" x 8" beam. The rafters are also 2" x 8" and spaced approximately 24" on center. The stringers are a generous 1 3/4" x 1 3/4" and are spaced approximately 12" on center. This is also a highly customizable pergola.


The Williamsburg Fiberglass Pergola allows you to match your house trim color exactly, or any other color you wish. Now you can have the look and adaptability of wood without all of the maintenance.  Fiberglass does not absorb moisture, so paint will adhere much longer.  With

our high quality factory ColorLast™ Painting Process, your paint should last many years before repainting is needed.


The strongest pergola kit on the market, it will provide you a lifetime of enjoyment. Another major advantage of fiberglass is its incredible strength. Without metal or wood inserts, you can have a freestanding pergola with an overall size of 26' x 26' with just four columns!  No other kit offers this kind of design freedom.

What is included in the pergola kit, what else do I need to supply?

Backyard America Pergola kits include just about all of the materials needed to assemble your pergola. Typically, you will need to supply anchoring adhesive to secure your columns to a concrete surface or pressure treated blocking and wood screws to secure your columns to deck framing. For pergolas attaching to a building wall, you will need to supply the appropriate hardware to secure the ledger to the building wall. An average kit will need less than $50 in additional materials, all of which should be available at a local home center.


How difficult is the installation?

Whether you are an experienced pro or a weekend warrior, all Backyard America Pergola kits are designed for easy installation and come with illustrated instructions and unlimited free technical support over the phone. No advanced tools or skills are needed to install any of our standard pergola kits.


How long does it take to install a typical pergola kit?

With two people, installation of the pergola kit itself will typically take a professional contractor a day or less, do-it-yourselfers should plan on a one to two day installation. This is for an average size kit and does not include time to dig and pour footings or attach to deck framing.


What tools do I need to install the pergola?

The most commonly needed tools are listed below. A list of the exact tools needed for your pergola kit is included with the instructions.

» 4' Level

» Measuring Tape

How do I attach a pergola to my house wall?

Attached pergolas typically include a ledger. The ledger will secure to your house wall using appropriate hardware for your wall type. The rafters of the pergola will attach to the ledger. Our estimators can provide attachment details and hardware recommendations.


How do I attach a pergola to my deck?

Our exclusive TensionRod Mounting System can be easily attached to deck framing with the addition of our universal deck framing mount adapter kit. This allows you to locate the columns for your pergola virtually anywhere on your deck while also ensuring your pergola will withstand all of the conditions nature can throw its way.


How do I attach a pergola to my concrete or paver patio?

» Our exclusive TensionRod Mounting System can be easily attached to a concrete patio or concrete footing by drilling a 5/8" hole and using anchoring adhesive to secure the supplied threaded rod.

» For paver patios, you will need to remove an area of your pavers, install a concrete footing to the top of the pavers, then reinstall the pavers around the new footing. This will give you a secure surface to attach to. The base trim supplied with our columns will then cover up the concrete footing and cut edges of the pavers to ensure a finished appearance.


Does the pergola kit come with instructions?

Yes. All Backyard America Pergola kits come with illustrated instructions that take you through the installation process step-by-step. Component and connection details are included so that you know what every part is called and how to put everything together. For custom structures, we supply detailed shop drawings that include column layout, component placement, and attachment details.


How many people are needed to install a pergola kit?

We recommend two people for a standard size pergola and three people for large or more complex custom pergola kits.
