Dear Clients,

Please, be advised that due to COVID-19 and related to its closures, many businesses experience a back up in orders as well as a material shortage. This affects our business’s performance as well and is out of our control.

There is a shortage of wood materials in ON that leads to extended delivery and waiting times.

Also, companies that make and supply us with railings are running behind their schedule and the delivery time to get the railing done was extended from two to eight weeks.

We really apologize for the inconvenience it causes you but the safety of customers and employees is a priority for businesses at these uncertain times.


Please be patient, smile and stay safe!

Demex Decks Team.
