Homestars Review
Deck and Walkway. After requesting a quote I was contacted by Aleksander from Alterra the next day. He came out a few days later and measured the area and spoke with my wife and me.

Frequently asked questions

How long it takes to build a deck?
The size of the deck should be taken into consideration, the more complex the deck design, the longer it may take to complete. On average, deck construction takes between 5 to 14 business days. The exact timeline for deck construction can be given after the project design has been surveyed and agreed upon.
How do building codes affect the cost of decking?
There are setback rules that determine how close you can build to property lines, as well as requirements for height, structural supports, and the size of railings and stairs. This means that the design you have planned can be changed and most likely the cost of the deck will change. Following the rules of construction will make the deck safer and it will serve you for a long time.
