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
James and Marlene HauflerI recently purchased a pergola kit from Baldwin Pergolas. It was a large custom pergola measuring about 16 by 36 feet. I am totally happy with the materials, workmanship, and customer support provided by Baldwin Pergolas. My wife and I were able to assemble the pergola over the course of a few days. (With a little help from two neighbors on the first day.) We found that everything fit together exactly as planned. Everyone who has seen the pergola, including our neighbors, and the building inspector (!), has been very impressed with the design of the pergola, the quality of the materials, and the precision of its construction. Their comments have included "beautiful", "amazing" and quite a few "wows" ! Our experience with Baldwin Pergolas has been completely positive. Their personal commitment to quality shows in everything they do. Thank you, James Haufler Sparks, Nevada
John MitchellMax, it does look spectacular in the evenings. One of these days, I'll try for a night photo that shows it off.
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.
Steve and RheaMax and crew, Rhea and I both want to thank you for a great job and lots of hard work. We are extremely pleased with the pergola, the quality of work and your own personal effort. Architecturally it brings a new dimension to the scale of the existing farmhouse by balancing the composition. Functionally it will bring years and years of enjoyment.
Mara CruzWe love it! Your assistance and patience during our installation was greatly appreciated.
Joe and SteveMax, We are so taken with our pergola. It is the perfect transition from the screened porch to the deck. We are so pleased with the entire transaction. If only we'd had the time spent with the deck people that we spent with you. The results are breathtaking. Take that from someone who works in millimeters.
Alan LuuI completed the project and like to share some of the pictures with you. Everything was putted together nicely with all your works already in place. Thanks for a job well done.
Kent WarkentinWow, Chris. I really appreciate your help on this effort. These plans are excellent and will definitely make my job easier. Again, thank you so much for your help. I will send you pictures when we get it all done. This pergola is the centerpiece of the Rosa Parks elementary school's outdoor classroom so it is a big deal to them that we are helping them out.
John EndicottOne of these days, I may be back in touch about a second pergola for the patio in front of my house. I am quite happy with the one you built here, which we use a lot in the summer.
Mr. EvansMy wife loves the fine details and I love the natural beauty of the cedar. Nice job. My neighbors are envious. Thanks for everything from the Evans in sunny Colorado!
