Hardie Board Repair and Section Replacement
Hardie Board (fiber cement siding) is one of the most durable siding materials available, but it is not maintenance-free. When seams are not flashed correctly, nails are overdriven, or caulking fails at joints and trim transitions, water can enter and lead to swelling, cracking or damage to the sheathing behind the siding.
At Arvada Handyman, we perform targeted Hardie Board repairs throughout Arvada, Candelas, Leyden Rock, Five Parks and Westminster.
We repair only the areas that are affected, restore proper water management and leave the repaired section blended cleanly with the rest of the exterior.
Why Hardie Board Needs Repair
Fiber cement itself does not rot, but the components around it can allow moisture to penetrate the wall structure. Most Hardie repairs we handle are caused by:
Gaps at butt joints where caulk has failed
Improperly flashed horizontal and vertical seams
Overdriven nails causing board cracking
Hardie installed too close to grade or concrete
Trim joints absorbing moisture at exposed cuts
Movement in structure that cracks the boards
Many homes in Candelas and Leyden Rock were built quickly during high-demand years. In some cases, the siding itself was installed correctly, but flashing and caulking weren’t given enough attention. Over time, water works into these weak points.
Common Signs of Hardie Board Damage
You may notice:
Cracks forming along nail lines
Swelling at ends of boards
Expansion or softening at seams
Paint peeling or discoloration along joints
Water staining or shadow patterns beneath siding sections
Even if the damage seems minimal, it is important to address it before water reaches the sheathing.
Our Hardie Board Repair Approach
Hardie repairs should not be rushed. We follow manufacturer-approved methods to ensure the repair is durable and compatible with the existing siding system.
Our repair steps typically include:
Evaluating the damaged section and surrounding seams
Removing affected boards carefully to avoid breakage
Inspecting sheathing, trim and flashing for water penetration
Installing replacement fiber cement boards with correct spacing
Adding or correcting flashing at butt joints and vertical transitions
Sealing joints using approved sealants
Priming and painting exposed cut edges and repaired sections
Matching texture, reveal spacing and paint is key to a seamless result.
Matching Existing Hardie Profiles
Hardie board comes in multiple sizes and textures. We match:
Profile (lap exposure)
Thickness
Texture or smooth finish
Paint sheen and color
This ensures the repair does not look patched or out of place. When necessary, we order specific replacement material rather than substitute with a similar product.
Why Flashing Is Critical for Hardie Systems
Hardie requires specific flashing at vertical seams and trim transitions. When this flashing is missing, water is allowed to wick into butt joints, leading to swelling and cracking.
Correct flashing prevents repeated failure and protects the underlying sheathing. We treat flashing as a priority, not an optional add-on.
