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
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.
Dan HarmonMax - i'm forwarding you some pics of the assembled pergola for (address). I am very pleased with how it came out, and all of the friends and neighbors who have seen it have given it rave reviews.
Becky HansenThanks Max. I'm glad you like the photos. We enjoyed working with you and your company even though it was long distance! We absolutely love our new outside room and so do neighbors walking by. In fact, I think I'm heading back outside now to enjoy the stars under our pergola. Take care and thanks for an outstanding product.
Elizabeth CarneyDear Max, Thanks again. We love the pergola. It's beautiful. We hope everything goes well for you.
Dan HarmonI was very impressed with how easily the assembly went - the process was intuitive, every part just dropped into place.

Christine Wrote: I feel the same way. The owners are very pleased & it went together like butter. I will get a you a good set of pictures. It was great working with you!
Jeff VeasmanThank you my friend, we just got done with the big pergola, it took longer to run the wires than it did to put the pergola together. It is freakin sweet Max, oh and by the way Deana Martin, Dean's daughter lives next door. We did a three story add on for them but she said it looks spectacular. Thanks again Max, I'll be sending some pics.
Jane Hastay and Peter WeissDear Baldwins, WE LOVE OUR NEW FURNITURE! It is so beautiful, comfortable and functional and it smells good too! We feel like we have a whole new outdoor room on our deck. Thank you for giving us a break on the delivery charges - the fellow who brought the furniture was a very nice young man. We're very happy with our choice. Sincerely,
Jeff RiddellAs a cabinetmaker and woodworker, I send you kudos on your system, the communication that we've had, the quality of the product. It's a pretty simple kit that arrived and it installs just about as easily as your website suggests. On a personal level, it's really cool to make connections with other people that have the same sense of pride in their work. This stuff is as much about service as it is product.
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.
