All our spiral staircases are custom built to fit your needs. A "Basic" spiral is constructed from welded steel with hardwood treads and a flat black finish. Each stair is shipped 95% complete, un-finished and un-attached. Our "Basic" stair comes equipped with a landing frame that is set at the correct elevation to accept your existing sub-floor and finished floor material.

A landing surface, landing rails and balcony rails to match your custom built spiral can be provided for an additional cost. We have a variety of materials for you to choose from so you can have an indoor or outdoor stair.
Services
Below prices are for units that are 7 to 9 feet, floor-to-floor, 3 1/2, 4 or 5-foot diameter. We advise 5-foot diameters for all staircases where possible. 5' diameter, 30 degree tread will fit most building code requirements. For spiral staircases, of course, we advise application and consultation with local building authority.
Have you explained to your contractor that the unit comes with treads unfinished, unsanded and unattached and there's no 2nd floor railing?. Does your contractor understand that the unit does not have deck (floor) on landing frame?. Does your contractor understand how to prepare shaft hole and make sure that there is enough room to get frame into building - need 36" minimum hole, "straight shot", (no hallway), for 5' diameter?.

I hired Bill Rupert of Maine Spiral stair case to build me a spiral staircase and a set of railings.i gave him a deposit in mid October, 2 months later the staircase finally showed up. after staircase was put up, Bill then measured for the railings. about a week later I received a quote on the railings and was asked to double check his measurements, good thing I did. he had one of the railings 18 inches longer than it needed to be.

I drew up a set of my own plans and sent to him with exact measurements on how i wanted railings made. on the right side of loft there was to be one long railing, on the left side there where to be two railings. one railing off the wall, and another to make the turn onto staircase landing. so another two months go by and Bill shows up a day late with the railings. the railing on the right side was pretty good and could be made to fit. however the railings on the left side which where suppose to be in two pieces where fabricated as one. well, when we tried to install the railing the angle was 12 inches off. when I questioned Bill as to why he made the railing in one piece as opposed to two pieces like I clearly specified in my drawing he had no answer for me. he asked for his check and out the door he went. pretty much told me that the correction was on me. so after paying him $5300 for staircase and railings, now I had to hire a welder to come fix his mistake.this repair is going to cost me $375-$400. my wife and I are very unhappy with the mess he left us with. we would not recommend Maine Spiral Staircase or Bill Rupert to do any railing work for anyone David Saucier New Hampshire
