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
Bill SchlaepferMax I want to thank you for the promptness with which you handled this problem. The way you have handled this speaks volumes about the quaility of your company. I would not hesitate doing business with you again. Thanks again.
Jim and Lina P.Max and All the Folks at Baldwin, My wife tells me you fixed the boot on our pergola and even left some extra stain for us. That is excellent service and the reason we purchased it from you. Please accept our sincere thanks, we are loyal customers and your best advertisement.
Charlie NicolaMax - Thanks for the instructions on assembling the pergola - went together nicely and looks great in our small back yard! Regards, Charlie
Ed MigliaccioThanks Max, We were thrilled with the way everything came out! The pergolas are absolutely stunning and fit our needs perfectly. I especially like the down lights at the fireplace pergola - I tried to get them to come out but the effect is much better at night. Thanks for all of your efforts.
John EndicottMax and Chris, Just wanted you to know how pleased I am with the pent roof you designed and fabricated. The fit came out perfectly, installation was easy, it\'s performing as designed (including headroom for my daughter\'s 6\'7\" fiance), and looks great, of course. Many thanks! Best,
Molly and Dave Stanley at Stanley Ranch, AZ.And here's how it looked at noon today. Mark said it went together very well, and they enjoyed working with your work. It surely has already made a wonderful difference in the quality of light coming into that entry room, as well as the overall looks on the house. We are very pleased with your good work and are planning a larger square pergola on another house at the ranch about this time next year.
Carol GarintherDear Max, The pergolas look great! The addition of rope lights was the key to the whole look. Thanks again.
Lyra V.We couldn't be happier. My wisteria is going up the columns, and its just stunning. We removed the trees and its just stunning. Thank you so much for all your time and hard work. Sincerely,
Christine Bullard DBA Complete Building ServicesHello Max, It took awhile but here are some pictures of the beautiful pergola. When were done with the project I would like to send you a better picture. I was great working with you & I’ll e-mail you when it is complete. Thank You.
