Our series on Hardie Installation 101 continues with information on pattern staging and some of the touch-up required at the end of the siding replacement project that will ensure proper product performance. These are the details that can easily be neglected by a remodeling company at the end of the project.

Exposure Setting

Hatch Homes will properly set each course of siding to ensure workmanship integrity and aesthetic consistency. Improperly setting plank course can result in the following conditions:
1. High-Nailing | Leads to siding that is fragile and clatters in high winds.

2. Nail Popping | The nail of the below course pops through the siding of the above course.

3. Uneven Siding | Unpleasant aesthetic. Siding does not run parallel to the foundation or below courses.

Pattern Staging

Well planned and executed pattern staging is critical in ensuring curbside appeal for any siding type. The siding pattern should be staged in a way that lends to randomness in which the seams are not grouped, concentrated or consistent throughout the home’s façade.

Flashing Details

Improper flashing technique is the number one cause of moisture related failures in residential construction. We recognize just how important this step is in your re-siding process. Failure to utilize the proper flashing details will ultimately damage your home and will create headaches and will potentially result in huge out of pocket expenses for you in the future.

We flash all fenestrations on your home. These areas are the single greatest weak points on your home. We also flash over horizontally installed trim, all brick wainscoting, kick-out flashing as necessary to shunt water away from side walls, and slip sheet flashing behind HardiePlank butt joints as necessary. If ColorPlus or pre-finished product is used, we will provide color-matched flashing.


We know that caulk is an important feature on your home. We use the types of polyurethane caulk that complies with ASTM-C834 or ASTM-C920. (As required by James Hardie). OSI QUAD and TiteBond are our preferred caulks. Both caulks remain permanently flexible, afford primer-less application and are completely paintable. All caulking will be professionally applied by skilled installers as the aesthetic value of caulk outweighs its benefits in preventing water intrusion. (Caulk will break down over time because of your home settling, seasonal weather changes, UV degradation and contraction and expansion. This is why the flashing details are critically important.

More than just a contractor.
