Bismarck Deck Construction
Project: Composite Deck Construction and Sliding Glass Door Installation
Adding new access and summer living space
This family was looking to expand their living space off the dining room with the addition of a 16’ x 20’ deck and a sliding glass door for access to it. They preferred composite decking and vinyl railings to keep it low maintenance, settling on Deckorators Tropics composite deck boards in Hana Brown to match the color of decking on the front porch.
An egress window on the west side of the deck area required a small “notch out” to accommodate access to the well and window. I suggested wide stairs for a more welcoming entry as well as easier movement of items on and off the deck. Skirting was constructed from CedarTone treated lumber for framing and the same composite decking that was used for the deck surface.
A sliding glass door, installed after completion of the deck surface, replaced a large south-facing window to provide access to the deck.

Bismarck Deck Construction FAQs
-
Yes. The City of Bismarck requires a building permit for new deck construction. Handyman Kota can help you with what's required before breaking ground. For full details, visit the City of Bismarck building permits page.
-
All new deck construction by Handyman Kota uses either composite decking (such as Deckorators or Trex) or AC2 pressure-treated lumber (all framing is pressure treated). Composite is a popular choice for its low-maintenance finish and long-term durability in North Dakota's climate — no sealing, staining, or painting required.
-
Residential deck construction can take anywhere from a week to several weeks to complete, depending on size, complexity, and materials selected.
-
Yes, railings are included as part of deck construction when required by code. Per Bismarck building code (in accordance with the IRC), any deck surface more than 30 inches above grade requires guards at least 36 inches high.
