HardiePlank sidingWhen you have a big remodeling project around the house, you definitely want to know an estimated time frame of completion so you can plan accordingly. Replacing the siding on your home involves a lot of details that can vary from project to project, so the time frame for installing HardiePlank® siding on your home would depend on the following factors:

The specifications of your home

  • The size
  • Two story vs. one story
  • Terrain around the home (i.e., whether the ground is level or sharply sloped)
  • The amount of landscaping that installers must avoid


The specifications of the project


The contractor you’ve hired 

  • The skill and experience level of the crew—the quality of work and speed of completion depends heavily upon this factor
  • The reliability of material delivery—using a reliable supplier who delivers the correct order on time will save a lot of time and headaches
  • The work ethic of the crew—an industrious, diligent crew will finish the installation in a much more timely fashion than one that is not focused and committed to working hard and doing what they promised


Uncontrollable Events 

  • Weather—wind, humidity, and rain can affect the installation of the Hardie materials and the installation of the paint coating
  • Emergencies and other last minute items that interfere with the project

How to know if you had a bad James Hardie fiber cement installation?

There are several signs that may indicate that you had a bad HardiePlank fiber cement installation:

  1. Visible gaps or uneven seams: If the seams between the HardiePlank boards are not even, or if there are gaps between the boards, it may indicate that the installation was not done properly.

  2. Warping or buckling: HardiePlank is designed to be a stable and durable material, but if it has been installed improperly, it can warp or buckle. If you notice any signs of warping or buckling in your HardiePlank siding, it may indicate that the installation was not done correctly.

  3. Water damage: If water is able to penetrate the HardiePlank siding and cause damage to the underlying structure, it may indicate that the siding was not installed properly. Signs of water damage include staining, mold growth, and rot.

  4. Poor caulking or sealing: Proper caulking and sealing are important for preventing water intrusion and ensuring a tight seal between the siding and the surrounding structure. If the caulking or sealing around the HardiePlank siding is poorly done or missing in places, it may indicate that the installation was not done properly.

If you suspect that your HardiePlank siding was installed improperly, it's important to address the issue as soon as possible to prevent further damage to your home. A professional siding contractor can evaluate your siding and recommend the appropriate repairs or replacements.



Here’s a scenario that may give you an idea of what a typical project might entail. If you’re having Pre-Primed HardiePlank siding installed, your home is considered average according to the aforementioned factors, and the contractor is following the James Hardie Siding Best Practices manual, the job will take approximately 10 to 12 days for the HardiePlank siding to be installed.  Then for the paint crew to apply a second primer and coat the siding, you can expect about 5 more days to be added, bringing your total work days up to about 17 or so.

As you can see, there are a number of factors that affect the time frame of your project’s completion date. It’s important that your contractor sets clear and reasonable expectations for you from the very start so that you can discuss everything with them, choose the dates that work best, and avoid ending up with a frustrating schedule conflict.
