Composite Decking VS Wood Decks
Composite decks are maintenance
Man made decking
is better than wood
Composite decking lasts
millions of dollars are spent to glamorize composite decking
products. I am faced with the task of deprogramming people
that are absolutely sure that all composite decking is wonderful. As a
tradesman and designer I get a chance to see these products after a few
years of service, with all their flaws exposed. It puts me in a
position to question the promises and dissect the language in
their marketing materials.
I've fielded hundreds
of phone calls and emails over the years from people that bought the
promises of the composite companies. Many were disappointed when the
warranty turned out to be void because the company just wasn't there,
wasn't honoring the warranty or their issue was excluded from their
warranty. The sad part is that most of the people didn't research the
product until long after they bought and they started having problems.
Its human nature I suppose; we trust too much. I find myself in the
middle of two groups of people equally as passionate and insensed with
We see the new decking shows where they
use nothing but Trex, (they sponsor the show), and everything looks so
wonderful through the camera's eye. They don't show you the details
that don't work--the shoddy workmanship or any of the flip side of that
coin, but I will spare you that rant. That's another article!
have heard noises recently about virgin PVC products being the focus of
a class action suit. PVC materials may have a tendency to be stained by
cooking oils, and tanning butter. If you apply tanning lotion and then
lay on the deck, you may have a permanent "Shroud of Turin effect." I
have noticed that the products go a bit chalky and fade out over time,
so there just might be merit to the claim. Maybe we can talk about that
law suit later in the year.
Class Action 2013
Trex has a conditional settlement
in place for its latest class action suit. The summary of it
is, they will pay you 20% of what you paid for the product or what the
contractor paid for the decking up front, and about 50 cents a foot
towards the labor to install it. We charge about $15.00 per square foot
to change decking on a typical deck, so 50 cents a foot is a paltry
amount. You won't get your decking changed that cheap. If you can live
with looking at the deck, take the money.
used a cleaner to try to get rid of the mold, and you kept the
receipts, they will pay you $18.00 a jug.
want to roll the dice once more and use their "New and Improved
decking", they will give you a 50% discount on decking and fasteners.
If you choose to remove the old decking, unfortunately you will have to
pay for the removal, transportation and disposal of the old decking.
That factor wasn't adressed in the agreement.
Trex has cured the problems with their decking by switching production
to their new cased product--and maybe the Ford Pinto, and Chevy Vega
will be discovered to be masterpieces of human engineering. There will
likely be fading issues, and the casing might be expanding and
contracting at a different rate than the core, so we will wait for the
jury on these new products and hope for the best.

omnipresent rumours of failures and unhappy clients. It
is becoming apparent that after a few years composites simply don't

issue of Warranty is not being addressed by
the composite companies. All but one manufacturer
that I have seen excludes the cost of disposal and labor to replace the
decking from their warranty. This is the composite industry
telling builders that they do not value their time. This is akin to
pitting our clients against builders across
the country. If you are a builder recommending composite to a
client for their deck, you are putting yourself in a potentially
position of being libel for damages, ie. you may be bound
to supply your labor for free to replace faulty composite decking. Lets
face it--if you make composite decking that is faulty, you cannot
ignore the fact that to make the client that purchased the composite
decking whole, you need to cover labor and disposal of the defective
decking. These companies are relying on slick
marketing rather than reputation.

Evergrain, when I searched, but you should do your own research before
buying any composite product. When you buy a man made product like

weigh all the factors. Most builders like the product, but how many of
them have that decking that they recommend on their own home

different methods for fastening and leaving tolerances (spaces) to
allow expansion based on temperature. Variance of about 150 degrees F
should be standard in North America, which means up to 2 or 3“ of
expansion should be expected with some products for a 20' piece of
decking. Most builders cut the material into shorter pieces so that
this expansion is easier to hide.
