How to Convert a Manual Awning to Motorized: Compatibility, Costs and Steps
Quick answer
Many manual retractable awnings can be motorized by replacing the crank gearbox with a tubular motor inside the existing roller tube, provided the tube diameter, end brackets and arm springs suit an available motor. Retrofit parts typically run $400 to $1,300, plus power work ($200 to $800 if an electrician adds an outlet) and labor. Conversions make sense on sound awnings with years of life left; on old or budget units, a new motorized awning is often the better value.
Yes, many manual retractable awnings can be converted to motorized. The conversion replaces the hand-crank gearbox with a tubular motor that slides inside the existing roller tube, then adds power, a remote and limits. Motor kit parts typically cost $400 to $1,300, a wind sensor $100 to $400, and an electrician $200 to $800 if you need a new outdoor outlet or hardwired connection. Whether it is worth it depends on three things: whether your awning's maker offers a retrofit kit, whether a motor fits your tube, and how much life the frame and fabric have left.
For background on motor types and sizing, see awning motors; for the overall picture, our motorized awnings guide.
Is your awning convertible?
- Roller tube type. It must be a hollow tube a motor can slide into. Most lateral-arm and drop-arm awnings qualify. Fixed-frame awnings cannot be motorized because nothing rolls.
- Tube inside diameter and profile. Common awning motors are about 45 mm (1.8 in) in diameter, with larger sizes for heavy systems. The tube's inside profile (round, octagonal, or grooved) determines which adapters fit.
- End brackets. The motor head must mount to the end bracket, often via an adapter plate. Some awnings need a different end bracket on the motor side.
- Maker's retrofit kit. Several awning manufacturers sell motor upgrade kits for their own manual models. This is the simplest route, because adapters and torque are pre-matched.
- Frame and fabric condition. Bent arms, worn arm cables or belts, corroded brackets, or fabric near the end of its life (solution-dyed acrylic commonly lasts about 8 to 15 years) argue for replacement over conversion.
- Power access. You need an outdoor GFCI-protected outlet within cord reach of the motor end, or a route for hardwiring. Battery-powered motors are an option for smaller awnings.
Not sure what you have? Look for a label on the end cap or inside the front bar, and check the maker's site for a "motor upgrade" or "motorization kit" for your model.
Conversion options
| Option | How it works | Best for | Watch out for |
|---|---|---|---|
| Manufacturer retrofit kit | Motor, adapters and bracket designed for your model | Awnings from makers that offer kits | Kit availability for older models |
| Universal tubular motor with adapters | Third-party motor with crown and drive adapters matched to your tube | Tubes of standard sizes and profiles | Exact adapter fit; head-to-bracket mounting |
| Battery or solar motor | Same, with a rechargeable pack | Small window and drop-arm awnings with no power nearby | Lower torque; not for wide lateral-arm units |
| External crank drive add-on | Motor that attaches to the crank eye from outside | Some light shades | Generally not robust for patio awnings; check rating carefully |
For most patio awnings, the first two options are the realistic ones.
Sizing the motor for an existing awning
On lateral-arm awnings, the motor must overcome the arm springs, which pull the front bar outward with substantial force. Typical lateral-arm motors range from about 30 Nm for narrower awnings to 50 Nm or more for wide ones, with heavier systems higher still. Use the awning maker's recommendation when available. Without one, an awning dealer or motor supplier can size torque from width, projection and number of arms.
Hardware on the motor side, such as end brackets and tube fittings, can differ between a model's manual and motorized versions. A maker's kit accounts for those differences; with a universal motor, you have to confirm each one yourself.
What a conversion costs
| Item | Typical range |
|---|---|
| Motor kit parts (motor, adapters, remote) | $400 to $1,300 |
| Wind or motion sensor | $100 to $400 |
| Smart hub or bridge (optional) | $100 to $300 |
| Electrician for outlet or hardwiring | $200 to $800 |
| Installer labor (if not DIY) | A portion of the $300 to $1,500 range for a full awning install, depending on access |
Worked example
A homeowner has a 14 x 10 ft manual lateral-arm awning, six years old, with sound arms and fabric. The maker sells a motor kit for $850 including remote. Add a vibration sensor at $200, an electrician to install a GFCI outlet near the motor end at $350, and installer labor of $400 to remove the tube, fit the motor and set limits.
Total: $850 + $200 + $350 + $400 = $1,800.
Compare with replacing the awning: a new motorized 14 x 10 ft unit installed might be $4,000 or more. If the existing fabric has, say, five years left before a re-cover ($500 to $2,000), conversion is clearly cheaper. If the awning were 12 years old with faded fabric and worn arms, the $1,800 might be better put toward a new unit.

Conversion steps (overview)
Read this first: Lateral-arm springs are under heavy tension. The roller tube must only be removed with the awning fully retracted and the arms secured as the manufacturer specifies (often with straps). Mistakes can cause serious injury. Many owners hire a technician for this part even if they do the rest themselves.
- Confirm parts. Match motor diameter, torque, adapters and bracket to your awning. Decide which end the motor goes on, based on outlet location.
- Arrange power. Have an electrician install a weather-resistant GFCI outlet with an in-use cover, or a junction box for hardwiring, before the motor goes in.
- Retract and secure. Fully retract the awning. Secure the arms per the manual.
- Remove the crank gearbox and tube. Remove end caps, the crank gear and, as required, the tube from its brackets, supporting its weight with a helper.
- Fit the motor. Install the crown and drive adapters on the motor, slide it into the tube until the drive adapter engages, and secure it per instructions (some require a screw or rivet through the tube into the drive adapter).
- Remount. Attach the motor head to its bracket or adapter plate, reinstall the tube, and route the cable with a drip loop so water runs off before reaching the motor head.
- Pair and set direction. Pair the remote and confirm "up" retracts.
- Set limits. Closed limit first, then open limit with at least one wrap of fabric left on the tube. Check fabric tension.
- Add the sensor. Pair and test the wind sensor by shaking the front bar.
- Test cycles. Run full cycles and watch for binding, uneven rolling, or the motor laboring near full retraction.

Warranty considerations
Installing a third-party motor may affect the awning maker's warranty on related parts, and the motor will carry its own warranty (typical motor warranties are about five years). A maker's own kit installed per instructions is least likely to cause conflict. Check terms before ordering; see awning warranties.
Convert or replace: decision guide
- Convert if the awning is under roughly 8 to 10 years old, the frame is sound, a kit or matching motor exists, and you mainly want convenience and sensor protection.
- Convert with a battery motor for small window awnings with no power nearby.
- Replace if the fabric needs re-covering soon, arms or brackets show wear, the awning is a budget model with no kit and an odd tube profile, or you want a cassette to protect the fabric.
- Stay manual if the awning is small, easy to reach and used occasionally. See motorized vs manual awnings for the trade-offs.
Frequently asked questions
Can any retractable awning be motorized?
Most retractable awnings with a hollow roller tube can be, but not all. The motor must fit the tube's inside diameter and profile, mount to the end bracket, and have enough torque for the arm springs. Very old, budget or unusually built awnings may lack compatible adapters. Fixed-frame awnings cannot be motorized because there is no roller tube.
Is it cheaper to convert or buy a new motorized awning?
Converting is usually cheaper: about $400 to $1,300 for parts plus power and labor, often $1,000 to $2,500 all in, versus $2,500 to $9,000 for a new installed motorized awning. Replacement makes more sense when the existing frame or fabric is near the end of its life, since you would soon pay for those too.
Do I need an electrician to motorize my awning?
Not if an outdoor GFCI-protected outlet is already within reach of the motor's cord and you use a plug-in motor. You do need a licensed electrician to add an outlet or hardwire the motor, typically $200 to $800, and local rules may require a permit. Battery-powered motors avoid wiring but suit smaller awnings.
Can I keep the manual crank as a backup after motorizing?
Usually the crank gearbox is removed and replaced by the motor, so the original crank no longer works. Some motors offer a manual override with a crank fitting on the motor head, which lets you retract the awning during a power cut. If you want a backup, specify a manual override motor when ordering.
