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.

Ellen BowenWe love our beautiful pergola! It's exactly what we wanted and we're really enjoying it. We've planted yellow Leverkusen roses and pink lemonade honeysuckle around the posts.
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!
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!
Eric BarberioAs a customer, I would highly recommend your company to others.
Ed MigliaccioThanks Max, We were thrilled with the way everything came out! The pergolas are absolutely stunning and fit our needs perfectly. I especially like the down lights at the fireplace pergola - I tried to get them to come out but the effect is much better at night. Thanks for all of your efforts.
