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
Pete and Susan LangSorry it has taken so long to get these pictures to you (a few years to be truthful). We love our pergola and also the furniture. It really does make the space like a room outside. Your product is fabulous. It was easy to assemble and it makes a profound difference in the space. it was a joy working with you and Cheri. We both hope you continued success in your endeavors.
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.
Dan HarmonBefore I made my purchase decision, I did get a quote from a local, highly-regarded pergola constructor. Baldwin's price was lower, and from what I've seen, I think the quality is higher. In summary, I'm pleased with how the pergola came out, and satisfied that I choose Baldwin as my supplier.
Tom PetrelliIt is awesome.
Rachel KiskerThe Baldwin Pergola looked great at the Boston Flower Show- I overheard many wonderful compliments from people in the crowd. I just know that you'll get many orders for it- in red! Thanks for designing such a lovely structure for us.
Lynn TempleThank you Max! You and your team are awesome and we are proud to have a "new" Baldwin Pergola!
Collette PalmerWe actually put most of it up last weekend. The pergola made such a dramatic difference in the backyard. I'm very happy with the investment.
James ShawThe pergola arrived safely, heck of a box you guys made. I fabricated the roof mounts, got the ledger installed, installed the columns and support beam - and wouldn't you know it... The rafters fit perfectly! I'd say it's a great success. 100% level and square - but took a lot of measuring. Thanks again! I'll send you guys some pics when I finish up and have the lights and fans installed. Just wanted to thank you for a heck of a product, I am very pleased.
Patrick DMy friend Max you amaze me a busy business owner reaching out to one customer and providing service that is not common any longer in this country. This is why US production facilities are far and few between and most going over seas, because someone forgot to pay attention to details. Your attention to detail is unwavering. You are a fine American and the team that works at Baldwin I believe can not be matched. A business is only as strong and passionate at its leader. Hats off once again to you and your wonderful conscientious team. First off please let me know my balance for this amazing piece of art that sits behind my home called pergola. Also would like to investigate the sunshade system for big pergola. Thank you again and again. Happy wife happy life! Peace Pat D
Dori PaulYou are wonderful. We sat in under the pergola each meal on Rosh Hashana and our guests said that they felt they were away at a beautiful restaurant or hotel!!
