Deck split open reveals the sins of the installer.
A film remains on the peel n stick membrane.
This film is like wax paper, preventing adhesion of the
coating to the membrane...duh!
Adding insult to injury, we found the "drains" were only pipes
stubbed up through the coating, and a cover placed on them to
make it look like a proper drain was there. But I caught ya!
This deck was installed on a new home 7 years ago...
the owner had several complaints,
causing the original installer to come back and redo the deck a few
years ago. But the deck was still cracking and a
leak at a drain was still a concern. Central Coast Waterproofing
opened the deck to find that everything was done wrong-
the peel n stick membrane violates the Class A
fire rating, the film wasn't removed from the membrane, preventing it
from adhering.The lath wasn't stapled properly, only about 8 staples
per square foot, instead of the required 16-20.
After the deck was opened, we found that the "drains" were just ABS
pipes stubbed up through the coating.
The whole deck was torn off, all new flashings put in
and a new deck system installed.
Final cost to fix it right $12,000.00
