Siding Repair in Jacksonville, FL
From Mandarin and Riverside to the Northside and the Beaches, we repair siding the way it should be done — finding the source of the moisture and fixing what’s actually wrong.
Jacksonville is a big, varied city — and the siding problems we see vary just as much. Older homes in Riverside and Avondale often have original wood lap siding that’s held up amazingly well but is finally showing rot at the bottom courses. Mandarin and the Westside have a lot of late-80s and 90s hardboard (Masonite-style) that’s now past its useful life and needs targeted repair or full replacement. Out at Jacksonville Beach, Atlantic Beach, and Neptune Beach, salt and wind dominate the conversation.
We diagnose what’s really going on before we touch anything, and we fix the cause — not just the visible damage.
Common siding problems we see in Jacksonville
Different parts of the city tend to fail in different ways. The repairs we run most often:
- Bottom-course rot on older wood siding in Riverside, Avondale, and San Marco
- Swollen, delaminating hardboard in Mandarin, Arlington, and the Westside
- Cracked and faded vinyl panels on 90s-era homes in Northside neighborhoods
- Wind-loosened panels and trim damage near Jacksonville Beach and Atlantic Beach
- Stucco/EIFS soft spots and water staining where flashing has failed
- Soffit and fascia rot from gutter overflow and clogged downspouts
Why so much hardboard fails in Jacksonville
A lot of homes built between roughly 1985 and 2000 used hardboard or composite wood siding products. They looked great when new and were inexpensive, but they don’t hold up to long-term Florida humidity. The lower courses absorb moisture, swell, then start to break apart. We can replace damaged sections and seal what’s left to buy you time, or plan a phased replacement if the failure is widespread.
Our repair process
We don’t guess. Every repair starts with an inspection — looking at flashing, caulk joints, paint condition, and the back side of any panel we can pull. Then we write a plan that fixes the moisture path, replaces damaged material, and blends the patch into the existing wall.
- Photo-documented inspection with findings explained in plain English
- Written estimate with materials, scope, and price clearly listed
- Repair only what needs repair — no upselling to a full replacement
- Color-match paint or factory-matched panels so the patch isn’t obvious
- Final walkthrough so you’re comfortable with the work before we leave
When to repair vs. plan a replacement
If less than ~25% of a wall is failing and the rest of the siding has years of life left, repair almost always makes more sense. Once failure is spread across multiple walls, we’ll talk you through whether continuing to patch is throwing good money after bad. Either way, you get an honest answer — not a sales pitch.
