An awning that won't retract in a wind storm isn't an awning — it's a sail. Most awning problems give you warning signs well before they become disasters. Here's what's broken, and whether it's worth fixing.
An awning that won't retract in a wind storm isn't an awning — it's a sail. And your RV is not a boat. We've seen awnings get torn clean off, take out the slide-out trim on the way down, and leave owners with a repair bill that makes the original awning look like a bargain. The good news is most awning problems give you warning signs well before they become disasters.
Here's the honest breakdown: what's broken, whether it's worth fixing, and at what point you're better off just replacing the whole thing.
The Most Common Awning Problems
Fabric is torn, fraying, or full of mold
Wind, UV, tree branches, and years of rolling up wet are the usual culprits. Small tears spread quickly. Mold that's deep in the fabric won't clean out — the fibers are compromised. A torn or heavily molded awning is a fabric replacement job, not a cleaning job.
Won't extend or retract smoothly
The roller mechanism has a torsion spring inside that provides tension. When it loses tension or the mechanism corrodes, extension and retraction become stiff or uneven. On power awnings, a motor failure or a blown fuse is the first thing to check before assuming the mechanism is gone.
One side droops lower than the other
The rafter arms that support the awning have adjustable pitch. Over time they lose tension or the locking mechanism fails. This also happens when one arm takes impact — low overhang, a branch, a misjudged campsite. Uneven pitch pools water in the low corner and accelerates the problem.
Arm won't lock open or keeps collapsing
The locking knuckle on the rafter arm has a cam mechanism that holds it open. These wear out and corrode — suddenly the arm folds up mid-use. This is a safety issue on windy days.
Water pools in the center
Awnings should be pitched slightly toward one end so water runs off. If yours sags in the middle, the pitch is off or the fabric has stretched. A pooling awning in a rain storm is carrying 40–60 lbs of water — that's how arms get bent.
What You Can Fix Yourself
- Fabric replacement on a manual awning — the fabric slides out of the roller channel. Replacement fabric is available by the foot for most standard widths. It's a two-person job and takes about 2 hours, but it's genuinely DIY-able with patience and the right fabric for your roller type.
- Fuse check on a power awning — if the motor does nothing, find the fuse (usually in the main panel or a dedicated fuse near the motor) before assuming the motor is dead.
- Pitch adjustment — most rafter arms have a pitch adjustment knob or bolt. Loosening, adjusting, and re-tightening takes 10 minutes and fixes water pooling.
- Cleaning mildew from fabric — a mix of mild soap and white vinegar scrubbed with a soft brush, then rinsed thoroughly. This works on early-stage surface mildew. If the black spots are through the fabric, the fabric is done.
Replacing just the fabric is almost always worth it
If your arms and roller are in solid shape but the fabric is wrecked, replacement fabric for a standard 15–17 ft awning runs $150–$300 depending on material. A brand-new awning assembly is $600–$1,200 installed. If the hardware is good, replace the fabric and get another 5–8 years out of it.
What Needs a Tech
- Torsion spring replacement — the spring inside the roller is under significant tension. Replacing it without the right tools and experience is genuinely dangerous. It's not a YouTube-and-hope situation.
- Power awning motor replacement — involves accessing the roller housing, disconnecting wiring, and ensuring the new motor is correctly calibrated for travel limits.
- Bent or cracked rafter arms — aluminum arms that have taken impact often look fine but are structurally compromised. A bent arm that fails mid-extension can drop the whole assembly.
- Full assembly replacement — if the roller tube is bent or the mounting brackets pulled from the sidewall, the repair involves the RV structure, not just the awning.
Repair vs. Replace — The Real Math
Here's a simple way to think about it:
- Fabric only damaged, hardware intact → replace fabric ($150–300 in parts, or $300–500 installed). Always worth it.
- One rafter arm bent or lock mechanism failed → replace the arm ($80–150 per arm). Worth it if the rest is solid.
- Torsion spring gone → repair ($150–250 in labor). Worth it.
- Roller tube bent, mounting brackets failed, or motor and fabric both dead → full replacement ($600–1,200 installed). At that point you're getting a new awning with a warranty.
- Power awning on an RV over 12 years old with multiple issues → full replacement and consider upgrading to a current-gen unit with wind sensors.
Common Question
How long should an RV awning last?
A quality manual awning fabric lasts 8–12 years with proper care — meaning rolling it up when not in use, never leaving it out in wind, and cleaning mildew early. The hardware typically outlasts the fabric by years. Power awning motors last 10–15 years. The things that kill awnings early: leaving them out in wind, rolling them up wet repeatedly, and UV degradation from full-sun exposure. If you store your RV, leave the awning rolled in — UV damage happens even when you're not there.
Awning repairs are one of those things that are very fixable if you catch them at the fabric-and-spring stage, and much more expensive if you wait until the arm fails mid-use and takes something with it. If yours has been acting stiff, drooping, or the fabric looks rough — bring us out before camping season and we'll tell you exactly what you're working with.
