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
Dan and Carolyn DeBlasioThe pergola was an easy set up and looks beautiful...just what the yard needed. I will send you pictures. Thanks again.
Tom PetitMatt, I just wanted to let you know how pleased I am with the new pergola. As a woodworker I appreciate the precision and thoroughness of the kit. I installed the cement pads the previous weekend and did the entire remaining installation in about 6 hours the following weekend with one helper. Very nice looking and I know I am going to enjoy the long term benefits of using a fiberglass products. I will send you a photo as soon as I finish the 10' dining table and benches that I am building to complete the pergola/dining area.
Found on Yelp.comhere is nowhere to buy wooden outdoor furniture of the same quality and for the same price. Nowhere! I own at least 8 pieces of Baldwin lawn furniture: two picnic tables with benches, a loveseat, two gorgeous adirondack chairs and a couple of other misc. tables and chairs by the pool. This furniture is so sturdy and dependable - and the design is fabulous! Check out their website, or sit in the furniture in person at North Cove Outfitters in Old Saybrook or at Baldwin in Middletown. You will be 100% sold. Our pieces have weathered wonderfully, and we leave them out year round. In the spring we pull them into the driveway one day and give them a good wash and put a quick restain on them. This is MINIMAL work, I assure you. And the furniture receives compliments from our guests year after year. This is a great family company with a great product. GREAT!
Michael & Maria D'AmbroseThe pergola has truly transformed our backyard into an outdoor paradise! We enjoy the hot tub every night. The privacy wall and beautiful drapery makes our pergola a wonderful enclosed outdoor room.
Steve and Rhea SchappacherWe love our house and greatly enjoy the pergola. Every evening is spent under our new outdoor room that the pergola has created. A few photographers have already approached us for use in magazines, I think we will wait until all work has been completed and when the landscape grows in more. All the best, Steve
Joe HollandThe Pergola is GREAT! What a difference it makes to the house ... inside and out. The height (for this sized Pergola) seems like it is matched up perfectly. The effect is a room outside the house. Let's see how many 'Wow's' we get Friday night. You should have left some of your business cards. My daughter (Sarah) loved the butterfly joint!
Ralph DeFalcoHello Max and Matt, I ordered a pergola from you in 2013 and have been just delighted with it. Looks great and is very easy to maintain with an annual pressure wash. See the enclosed pic of the pergola in the 'Low Garden.'
Jeff LauferMax, I will send you some photos as soon as we install the paddle fan. Running wire was fine. It looks great!
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.
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.
"First, man defines his architecture. Forever after, his architecture defines him."
It's been a tremendous honor to design and build these fantastic structures for our customers. We look forward to upcoming challenges and the beauty they bless us with.
