That being said, they are very simple to install.


First our drivers (if personally delivered) will help you get the stair to your location where he will explain how to install.


First – Mount the landing with the 4 lag bolts supplied.

2nd – Set the stairs up to the landing (3 to 4 people needed) and clamp the landing and the stair together. 3″ or 4″ C-clamps work best. You’ll need 2 clamps.

3rd – Level the landing & plumb the stairs.

4th – Walk up the stair to drill 4 holes 3/8″ in the landing using the 4 holes in the landing bar as guides.4


Before you climb up the stairs, make sure the C-clamps are tight and always have at least 2 safety people holding on to the stair for additional support and safety.


5th – Bolt the star and landing together using the counter sink 3/8″ bolts supplied.

6th – Bolt the center pole & balusters on the bottom step to your concrete pad or floor.

7th – If you ordered any extra rail for around the top you can install it at this time.

8th – If your stair is all metal you are done. If you ordered wood treads and wood handrail, it will need to be finished. Stain and finish all wood parts and install. Steps are fit at our shop & numbered from bottom to top.

Our spiral stairs are already assembled at our factory to your personal specifications. Having the staircase already welded together means that you simply bolt the top landing up to where it goes, set the staircase up to the landing and vice grip the landing to the landing bracket. You will need to drill 4 holes into the landing then use the bolts supplied to bolt them together. Then bolt the base plate and the tabs on the bottom balusters down to the floor. If your stair is all steel you are done. If you have oak treads and or handrail, it comes un-finished. You will need to stain and finish the wood to your satisfaction and use the screws supplied to attach the wood parts to the stair.

Goddard Steel Spiral Staircases are usually built in 1 piece. Our customers often ask “how do we get them into the house”? A 5’ diameter steel spiral staircase will cork screw through a 36” door that measures at least 34 ½” from jam to jam. You will need to have a straight shot to where the staircase will go. The staircase will not fit down a hall way or through a small entry way getting them into the house. If you have a hall way that is not large enough for the staircase to go through we can build your staircase in 2 sections and bolt them back together using only 7 bolts and screws.

Your custom made spiral staircase usually arrives at your home by our personal truck. You the customer will need help to unload the staircase and take it to the yard (exterior) or into the house (interior). Our driver is usually capable of helping you with this. Steel staircases are welded into a single unit but can be made in 2 pieces to get it into your home.
