Werner D6228-2
Best OverallPros
- Excellent stability with I-beam design
- Smooth, reliable rung locks
- High 300 lb duty rating
Cons
- Heavier than some competitors
- No leveling feature on uneven ground
The Werner D6228-2 is a workhorse extension ladder built for frequent use. Its aluminum I-beam rails provide superior torsional rigidity, reducing wobble when you are reaching sideways to clean windows. The rung locks engage positively and release smoothly, which owners consistently praise for safety and ease of use.
At 37 lbs, it is not the lightest ladder, but the weight translates to a solid feel that inspires confidence at full extension. The D6228-2 meets Type IAA rating (300 lbs), accommodating most users plus tools. For window cleaning on two-story homes or commercial buildings, this ladder delivers the stability needed for safe work.
Little Giant Leveler
Best for Uneven GroundPros
- Built-in leveling system for slopes
- Versatile multi-position use
- Compact fold for transport
Cons
- More complex mechanism
- Higher price point
The Little Giant Leveler solves the common problem of uneven ground at job sites. Its patented leveling system allows you to adjust each leg independently, keeping the ladder stable on stairs, slopes, and irregular surfaces. This feature is invaluable for window cleaners who work on older homes with uneven landscaping.
Beyond leveling, this ladder converts into an A-frame or extension ladder, adding versatility. Owners appreciate the sturdy feel and the ability to fold it down to a compact size for storage. The trade-off is a slightly more complex setup compared to a traditional extension ladder, but the safety benefit on uneven ground is significant.
Louisville Ladder AE2232
Best BudgetPros
- Very affordable price
- Lightweight at 28 lbs
- Solid build for the cost
Cons
- Lower 250 lb duty rating
- Not as rigid as premium models
The Louisville Ladder AE2232 offers excellent value for homeowners and light-duty professional use. It provides a 22-foot reach, sufficient for most two-story window cleaning tasks, at a fraction of the cost of premium models. The aluminum construction keeps the weight down to 28 lbs, making it easy to carry and maneuver.
While it lacks the heavy-duty feel of the Werner D6228-2, the AE2232 is well-built for its price class. Owners report that the rung locks work reliably and the ladder feels stable when properly set up. The Type I rating (250 lbs) is adequate for most users but may be a limitation for larger individuals carrying heavy tools.
Werner MT-22
Best LightweightPros
- Very lightweight at 22 lbs
- Easy to carry and position
- Smooth rung lock operation
Cons
- Lower 225 lb duty rating
- Less rigid at full extension
The Werner MT-22 is designed for users who prioritize portability above all else. At only 22 lbs, it is one of the lightest extension ladders in its class, making it ideal for window cleaners who carry their ladder between jobs or up stairs. The aluminum construction is durable yet easy to handle.
This ladder uses Werner's TwinStep rung design for comfortable standing. Owners note that the MT-22 is surprisingly stable for its weight class, though it does flex more than heavier models at full extension. The Type II rating (225 lbs) is a limitation for heavier users, but for lighter professionals or homeowners, this ladder is a joy to use.
Gorilla GL-20
Best CompactPros
- Compact folded size for storage
- Converts to A-frame and scaffolding
- Solid 250 lb rating
Cons
- Heavier than expected for size
- Shorter max reach
The Gorilla GL-20 is a multi-position ladder that excels in compact storage. When folded, it takes up minimal space in a garage or van, making it ideal for window cleaners with limited storage. It converts into an extension ladder, A-frame, or even a small scaffolding setup for working at mid-height.
Despite its compact folded size, the GL-20 is relatively heavy at 34 lbs due to its robust hinges and locking mechanisms. Owners appreciate the versatility but note that the extension mode is shorter (20 ft) compared to dedicated extension ladders. For single-story homes or low two-story work, this ladder is a practical all-in-one solution.
What to check before buying an extension ladder for window cleaning
Choosing the right extension ladder for window cleaning requires careful consideration of several key factors. The wrong choice can make the job harder or, worse, unsafe.
Reach height. The ladder should extend at least 3 feet above the roof line or window you are cleaning. For a standard two-story home (about 20 feet to the eaves), a 28-foot extension ladder is recommended. For single-story homes, a 16-20 foot ladder usually suffices.
Duty rating. Extension ladders are rated by weight capacity. Type IAA (300 lbs) is the strongest and safest for frequent professional use. Type I (250 lbs) is suitable for most homeowners. Type II (225 lbs) is for light-duty use only. Always choose a rating that exceeds your total weight plus tools.
Material and weight. Aluminum is the standard for extension ladders due to its light weight and corrosion resistance. However, lighter ladders often have lower duty ratings. Consider how often you will carry the ladder and choose a weight you can handle safely.
Rung lock mechanism. Look for smooth-operating rung locks that engage positively. Werner's spring-loaded locks are widely praised for reliability. Avoid ladders with sticky or difficult-to-operate locks, as they can be dangerous when adjusting height.
Stability features. For window cleaning, stability is critical. Look for I-beam or D-shaped rungs that provide a comfortable standing surface. Some ladders include slip-resistant feet or leveling systems for uneven ground.
Mistakes to avoid when using an extension ladder for window cleaning
Even the best extension ladder for window cleaning can be dangerous if used incorrectly. Avoid these common mistakes to stay safe.
Overreaching. Never lean sideways or stretch beyond your center of gravity. If you cannot reach a window comfortably, move the ladder. Overreaching is a leading cause of ladder falls.
Incorrect angle. The ladder should be set at a 75-degree angle (1 foot out for every 4 feet up). A ladder that is too steep or too shallow increases the risk of slipping or tipping.
Ignoring ground conditions. Always check that the ladder feet are on solid, level ground. On soft soil, use a ladder leveler or a wide base plate. Never place the ladder on loose gravel or wet grass without stabilization.
Using a damaged ladder. Inspect the ladder before each use for bent rungs, cracked rails, or worn feet. A damaged ladder can fail without warning. Replace any ladder that shows signs of structural damage.
Carrying tools while climbing. Use a tool belt or a hoist to bring tools up. Climbing with tools in your hands reduces your grip and balance, increasing the risk of a fall.
FAQs
What is the best extension ladder length for cleaning two-story windows?
A 28-foot extension ladder is typically recommended for two-story homes, as it provides enough reach to safely access second-story windows and eaves.
Can I use a fiberglass extension ladder for window cleaning?
Yes, fiberglass ladders are non-conductive and heavier, making them suitable for electrical work, but aluminum ladders are lighter and more common for window cleaning.
How do I secure an extension ladder against a wall for window cleaning?
Always set the ladder at a 75-degree angle, ensure both feet are on solid ground, and use a ladder stabilizer or standoff to prevent the ladder from shifting sideways.
What is the weight limit for a Type IAA extension ladder?
Type IAA ladders have a duty rating of 300 lbs, which includes the user plus any tools or materials they are carrying.
Are Little Giant ladders worth the extra cost for window cleaning?
Little Giant ladders are worth the investment if you frequently work on uneven ground, as their leveling system significantly improves safety and stability.
How often should I replace my extension ladder?
Replace your ladder immediately if you notice any cracks, bent rungs, or damaged feet. With proper care, a quality aluminum ladder can last 10-15 years.
Can I use an extension ladder on stairs for window cleaning?
Yes, but you must use a ladder leveler or a stair-leveling attachment to ensure the ladder feet are stable and level on the uneven surface.
What is the difference between Type I and Type II extension ladders?
Type I ladders have a 250 lb duty rating for heavy-duty use, while Type II ladders have a 225 lb rating for medium-duty tasks like home window cleaning.
Do I need a ladder stabilizer for window cleaning?
A ladder stabilizer is recommended because it increases the ladder's footprint against the wall, reducing sideways movement and protecting window frames from damage.
How do I store an extension ladder to prevent damage?
Store the ladder horizontally in a dry area, off the ground, and away from direct sunlight. Avoid leaning it against walls for long periods to prevent warping.
