Fiberglass vs Plastic Pergolas
Both fiberglass and plastic pergolas offer the benefit of a low maintenance outdoor structure. There are two types of plastic pergolas currently available, the first and most common is constucted from vinyl(also known as PVC). The second type of plastic pergola is constructed from a material similar to composite decking(Azek or Palite). These are low maintenance materials, however they differ significantly in terms of quality, lifetime and finish. Below is a detailed comparision of these materials.
Fiberglass
* Maintenance free
* Available in any color
* Structural material with free-spans of up to 20'
* Will not mildew, mold or yellow
* One piece CNC rafter tails
Vinyl
* Low maintenance but will mildew and yellow over time
* Non-structural vinyl tubes
* Pressure treated lumber is inserted into the vinyl and can sag, twist and rot
* Available in a limited number of colors
* Snap-on rafter tails
Azek
* Requires bi-annual painting
* Yellows and mildews over time
* Sheets of Azek are glued to either aluminum or lumber for structural support
* Azek will delaminate and fall of over time
* High cost of ownership

Azek Pergola Fail
Mildew
This Azek pergola was poorly constructed. It experienced yellowing, excessive rot and sagging as a result of the manufacturer cutting corners.
Beams
This what the main structural support beam looked like when the Azek fell off and the remainder was removed.
Baldwin to the rescue!
The client's contractor reached out to us and we replaced the existing structure with a fiberglass pergola that will last for years to come.
Testimonials
Lou and Barbara RicciMax, the pergola went up in a snap and we are very happy with it. We've recieved many complements already!
Missy SiennaI thought I would share with you some of the photos I took tonight of the grape arbor! It looks beautiful--I almost hate to cover it with grapes!
Dennis HoslerI am putting in the patio with the dimension to fit the pergola on top. Thanks for your responses. You have good customer service. Your website looks great. Keep in touch with anything new or upcoming. God bless.
Glenn ScottMAX!!!! You are unfriggin believable! This thing went together so easy I still can't believe it. Especially when I went to measure down 28 inches on the posts to set the gussets and found that you had already put lines there.....Your attention to detail was great. This whole thing slid together. I didn't have to touch one piece with anything but my hands. The most labor intensive part was screwing down all the purlins at the end.
George G. Stumpf, APLDThe pergola is spectacular, and my clients are absolutely thrilled. Just as planned, it totally transforms the patio area into an inviting, dramatic, and complete outdoor space. They are very impressed with the precision of the construction as well. Thank you again!
