Understanding Dry-In and Its Importance with New Construction

Understanding Dry-In and Its Importance with New Construction


Before any interior finish work begins on a new construction project, the house or building must reach the point called dried-in.” In some parts of the country, an inspector will check to ensure that no shortcuts have been taken in the process. Once the building passes the dry-in inspection, construction work can continue with the assurance that everything inside the building will stay dry.

What Does it Mean to Dry-In?

What Does it Mean to Dry-In?


When a structure’s dry-in is completed, it can effectively keep the elements out to ensure that weather-sensitive materials aren’t damaged by rain, wind, snow, or other factors. This also helps decrease project delays due to inclement weather.

Why is it Important to Dry-In?

The term dry-in is significant in the construction industry because it establishes the point in the construction process where the rough exterior work has been completed: windows, doors, roofing felt or shingles and a weather-resistant barrier have all been installed. The contractor can turn their attention to the next stage in the process — roughing in the electrical, plumbing and mechanical components.

How Dry-In Protects Buildings

The term dry-in” is used because it means the building is basically waterproof at this point. Finish materials can be stored inside the shell without fear of damage from the elements, and those working on the structure can complete their work under favorable conditions, taking their time to get the task done right the first time.

Once the building has been dried in, the contractor can take this opportunity to protect the foundation walls and slab from water damage by applying waterproofing products to the walls and floors. This is the best time to address this, as there is no need to protect finished walls and floors during their application.

What Does Dry-In Protect Against?

What Does Dry-In Protect Against?


Before reaching dry-in, the building and everything inside it are subjected to all the elements of nature. Dry-in is the focus of preventing damage from these elements:


Wind can cause a lot of damage to a building during construction. It can blow away materials like shingles and roofing felt, and it can also cause water to leak into the building through window and door openings. A weather-resistant barrier, which is applied before dry-in, will protect the structure from wind-blown rain entering through the walls. This prevents moisture accumulation in the walls and the possibility of mold forming after the building is completed.


Rain can also cause serious damage to a building while it is under construction. Before the building is dried in, water can leak into the building through unprotected wall and roof sheathing and cause water damage, mold and mildew. Storing finish materials inside a building before the exterior envelope is secured is risky and could lead to lost time and money.


Snow can be even more dangerous than rain during construction. If it is allowed to accumulate on unprotected surfaces, it can rot the material it is sitting on while slowly dripping into the building over an extended period. Completing dry-in in areas subject to snow should be a top priority.
