Aluminum Stairs Built for Steep Banks and Shorelines

Most waterfront lots in the Lakes Region don't have a gentle path to the water. They have a bank, a bluff, ledge, or a slope that gets steeper halfway down. Our stairs are made for exactly that ground. Each tread adjusts to the angle beneath it, so the stair follows the bank instead of forcing the bank to be cut and filled to fit the stair.

Every stair is fabricated in our own shop at 204 Casco Road in Naples, Maine, and installed by our crews from Sebago Lake to Martha's Vineyard.

How Many Steps Do You Need?

Measure straight down: take the vertical drop from the top of your bank to the bottom in inches and divide by 7. That's your step count.

Or measure along the slope: run a tape down the bank itself and divide by 13.

Example: a 70-inch drop ÷ 7 = 10 steps. A 130-inch slope ÷ 13 = 10 steps. Because every tread adjusts, you can round up or down.

Built for the Ground You Actually Have

Steep and uneven banks

Because the rise changes step by step, one run of stairs can handle a bank that's steep at the top and flattens out near the shore, without a contractor reshaping the slope.

Bluffs and long runs

Longer runs break into sections with landings and platforms, so a climb from a high lot to the water stays safe and comfortable.

Light on the land

The system goes in with hand tools on driven pipe legs, with no heavy equipment and no poured concrete. That keeps disturbance to the shoreline low, reaches lots machinery can't, and means the stairs can come back out if they ever need to.

Frequently Asked Questions

How do I know how many steps I need?

Measure the vertical drop in inches and divide by 7, or measure along the slope and divide by 13. A 70-inch drop is about 10 steps. The treads adjust, so a close count works.

Can the stairs follow a bank that changes steepness?

Yes. Each tread adjusts to the slope beneath it, so the stair follows the shape of the bank instead of requiring the bank to be dug out to fit.

What are the stairs made of?

The frame is 6063-T6 aluminum. Fasteners are stainless steel, separated from the aluminum by nylon washers to prevent corrosion between the two metals.

Do the stairs need concrete or heavy equipment?

No. They install on driven pipe legs with pipe feet that spread the load on soft ground, using hand tools. That also means the system can be removed later.

Are the stairs engineered?

Yes. The stair system is a PE-engineered product with engineering on file with our engineer of record. If a project needs its own site-specific stamp, we quote it as a line on that job.

Can the stairs connect to my existing dock?

Usually. J-brackets attach the stairs to most docks and fixed structures, and gang planks bridge the gap where needed.
