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
Michael DivittoNothing but rave reviews on the pergola. You really out did yourself.
Jared AsweganDear Max, It's funny what can happen when the three stooges set out to erect a pergola. While we were ultimately successful, the process was a bit dodgy. Of course, had we curtailed our enthusiasm and actually READ the instructions first, it would have gone a lot easier. What ever damage was done was easily mended thanks to wood glue, a couple of hidden screws and some touch up paint. I couldn't be happier with your fantastic work. From the beginning to the end of the process it was so easy, and I have admit, the pool area is so much improved with this addition. Absolutely PERFECT. I'll send photos next time the sun is out. Oh yeah, we built it in the rain and it only took about four and a half hours. Many MANY Thanks!
John MitchellThe finished pergola is stunning. We've already received many complements.
SteveThanks so much, Matt. The craftsmanship of your Pergola is outstanding. My wife and I love it. Thanks again!
Chuck KrickMax, We couldn't be any happier with our new Baldwin pergola. We get a lot of jaw dropping when people see the project and they are drawn to the pergola. The service and quality you provided was outstanding. Our landscaper and his assistant did the construction of the pergola in only 4 hours. It's amazing the "warm" feel the structure provides even though it is so open. My wife and I sit out and chat for hours every night. Looking forward to ordering some Adirondack chairs soon. Regards, Chuck Krick
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.
Jamie DunstI just want to tell you working with you and putting up the pergola was a pleasure. It went together like a dream and you have obviously put a lot of thought into the design and the way everything fits so well. I must admit, before my neighbor approached me about this project I didn't know what a pergola was, at least not by name. Now I know and it has been great to be part of this project. Thanks for answering all my questions along the way.
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.
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,
Ted YipThe pergola looks amazing and you and your team went above and beyond the call of duty. I'd also like to thank you for helping to get our kitchen cabinets off the delivery truck and into our driveway. You and your team have been true professionals and I would be glad (and proud) to be a referral in the future. I'll be sure to send pics once the outdoor kitchen is completely installed. Thanks again.
