DIY Banisters | Still Dreaming of a Finished Basement

July 3, 2018

I’m still dreaming of a finished basement over here. That means a lot of things including finishing the stair railings/banisters.  DIY banisters.   Finishing those banisters was probably the most intimidating thing I have ever done.  It requires finding something other than a 90 degree angle.  Admittedly, I was never really good at geometry and this task required my protractor skills to be sharp.  My Sophomore year of high school I had a geometry teacher who absolutely lived for math.  I am not sure he spoke any other language than angles and corny jokes.  I remember more about the jokes than the math….oops!  We are all wired differently, right?  Give me any power tool but please don’t make me think about angles!

When we built the house I knew that I wanted to have wood railings with iron balusters so I had them just finish half walls (or pony walls) and “I would do it later” due to expense.  That sounds really awesome in the moment.  But then the actual moment comes when you have to do the work and you regret ever saying it.  Now,  I would never be crazy enough to attempt to finish the stair railing if it was in the entryway or on a large staircase, but again, I thought “how bad could it be?”.  Famous last words.

If you don’t know my basement journey, I have taken my basement from abhorrent to amazing and you can read about that here.  And then I built a GIGANTIC entertainment center which you can read about here.

How I Began the Project:

I started by taking the half walls down with my reciprocating saw.  I now call it “the recip saw” because that’s what the pros call it and I am now a pro, lol.  That was the easy part.  Tearing things apart is always the easiest part of any reno.   I was left with a gaping hole.  That stayed that way for a little while and then I added a temporary board on top to get through the holidays when everyone was home so nobody would break their leg by falling in the hole.

Once the holidays were over and the kids went back to school I replaced the temporary piece of wood with a solid piece of oak on top of the stair skirt which is called a knee wall.  It cost me about $80 for the two pieces I needed for each rail section.  This would anchor the iron balusters.  I had to find the angles of the two ends of the board to connect it to the wall and connect it to the vertical piece of wood that the newel post would be screwed into.  I had to use my track saw to cut down the boards to the right size and then I had to take my router and create a nice edge on them.  I am sure that I could have ordered them, but it was less expensive this way and I already knew how to do it.

Did you hear me say angles?  Funny thing is that I understand more about angles now than I ever did before.  RANT: I think we learn things easier when they are applicable to our lives so teaching a 15-year-old about angles that do not impact or apply to their life in that moment or is interesting to them is a funny concept.  Or maybe I should have just listened better. RANT END.

Finding the angles was the worst and hardest part for me.  And one angle isn’t the same as another.  I got re-acquainted with my protractor…we understand each other now.  I do a lot of my DIY because I want to be careful with my dollars and also because I love to learn new things and be challenged.  The knowledge can be applied to projects over and over and I love that!

I ordered some box newel posts off of eBay that cost $60 each.  A LOT less than the ones I can order at Home Depot.  I cut them down to the size required by code.  (If you are doing railings yourself, make sure that you check your state building codes.  Your banister has to be a specific number of inches off the steps and balusters have to be a certain number of inches apart.)  I used REALLY long screws to attach them to the skirt.  I stained everything and was so excited to see it all working out.

Next up….hand rails.  You see the piece that is on the wall that the top of the rail goes into?  It is called a rosette and I made it. I made two…one for each set of stairs.   I could have bought them at the store, but I had some left over oak so I cut and routed my own.  It was really easy and saved a little money. They were installed by using liquid nails and my nail gun.  I also bought this 12′ hand rail at Lowe’s for $75.00.  It was a really good deal!  But at 12′ it was too long for the car so we had to strap it to the roof and pray for the best as we got it home!

It took me a while to work up the courage to cut it.  Again….angles.  I took an extra 1 x 2 and cut it to the right dimensions.  It allowed me to get it perfect and work out all the kinks before cutting the actual rail.  A very inexpensive way to make a template.  I transferred the angles onto the rail and then I held my breath as I cut….they turned out perfect!  Whew!  I stained them after they were installed.  I used angled holes to screw them into the rosettes and the newel posts. (Please excuse the Instagram photo…it’s all I had!)  TIP:  Start the angled hole as a regular hole and with your bit and then slowly angle it as you progress to become an angled hole.

Next up?  Iron Balusters.  We have simple knuckle and straight balusters upstairs so I decided to put simple, square iron balusters in the basement.  I also ordered them from eBay for about $120.00.  Typically when you order iron balusters you also order angled shoes to go at the bottom of each one to cover the holes.  I ordered them and they are so simple to install.  The balusters came a lot longer than I needed so I got a special blade for my recip saw to cut metal and my husband cut them down to the correct length for me.

I drilled holes into the hand rail and the oak board at the bottom for the balusters to fit into.  It took a lot of measuring to find exactly where they should be according to code.  I first drew a chalk line in the center of the oak board  from top to bottom.  Then I marked where the balusters were to be placed, 4″ apart according to Indiana code. (Remember, each state code may be different.)  I then drew a line in the center of the underside of the hand rail.  From every 4″ mark I made on the oak board, I took my level vertical and made a mark on the underside of the handrail.  I referred to this video and it was SO helpful!

I dry fit the balusters  to make sure they were just right and took them all back out and then stained the hand rail in place. That way I could stain it all at once.  Once that was dry, I inserted the balusters, glued them in place and tightened the angled shoes.  I stained little oak plugs and covered the holes where I attached the boards, newel posts and hand rails.  I am so proud of myself and so excited to see that it all came out exactly as I planned!!!

Total Cost for two DIY banisters:

Oak boards and rosettes:  $90

Newel Posts:                        $120

Hand Rail:                            $75

Balusters:                              $120

Misc. items:                          $20

Total:                                     $425

I can’t believe the cost!  The real cost is in the labor. I could have used Poplar which would have saved me even more money as it isn’t as expensive as oak.  So, there’s another tip!  I still have some touch up work but will do all of that once the big projects are done.

Do you think you would be nuts enough to attempt creating your own banister? I would love to hear about and see your hardest DIY projects!!  Leave a comment below and tell me about it.  Have a great week!
