Stairs & Railings
Custom Stair Installation in University City, Philadelphia
Treads, risers, stringers and skirt board, built to a drawing instead of a catalog page. In University City, Philadelphia the median home dates to 1970 and 40.2% of the housing predates 1940, which changes what Deco Hardwood Floor expects to find before the work starts.

Building or rebuilding a stair in an old house
In University City the existing stairs were built in place a century ago, and deciding what can stay is the first part of any stair job.
Old stairs here are often steep and narrow, with treads worn hollow in the middle and a newel post that moves when it is leaned on. Some of that is repair: new treads on a sound frame, balusters reset, a newel fastened properly. Some of it means rebuilding the stair.
The difference matters beyond the carpentry. A stair that is replaced is generally held to the current building code, and one that is repaired is treated differently. Which one applies to your stair is a question we settle with the local code office before the quote, not after.
Before you get a quote
Winding steps at a turn are common in this housing. They are the hardest part of a stair to rebuild, and the place where a drawing done on site matters most.
How the housing in University City compares
Of the 6,231 housing units in University City, roughly 2,500 were built before 1940 and approximately 3,300 before 1978.
That makes the housing here newer than the 132 Philadelphia neighborhoods in our data taken together, where approximately 82.8% of 733,961 units predate 1978, and below the 60.5% figure for our whole service area. By the share built before 1940, University City ranks 77th of those 132. The full table is published as open housing data.
Within Philadelphia, the oldest housing in our data is in Cedar Park, with a median year of 1925, and the newest is in Kensington, Old, at 1997.
| Place | Median year built | Built before 1940 |
|---|---|---|
| University City | 1970 | 40.2% |
| Powelton | 1955 | 38.5% |
| Mantua | 1951 | 42.5% |
| Spruce Hill | 1937 | 53.4% |
| West Powelton | 1961 | 40.0% |
| Fitler Square | 1929 | 67.1% |
| Belmont | 1929 | 67.8% |
For stair work, the pre-1940 share is the figure to watch. Stairs of that age were built in place by hand, and deciding what can stay is the first part of the job.
What is usually under the floor here
Housing this old normally holds narrow strip oak laid straight over joists, and often it has only one sanding left.
In a place where a large share of the housing predates 1940, the floor under the carpet is usually the original one. That means narrow strip oak, sometimes heart pine on upper floors, nailed straight to the joists with no plywood in between. It also means the floor has probably been sanded before, possibly more than once.
Only the wood above the tongue can be sanded, roughly a quarter inch on a traditional floor. A floor that has already given up two of those sandings is a different job from one that has given up none, and the difference is not visible from standing height. We measure at the edge of a board before quoting.
Worth knowing here
Parquet and herringbone turn up under carpet in this stock more often than people expect, and they sand differently: the grain runs in two directions at once, so a drum sander used the normal way tears them.
Whether the federal lead rule applies depends on the house
Approximately 53.7% of the homes here predate 1978, so it comes down to the specific address.
This is a place where the housing stock straddles the 1978 line the EPA rule draws. Roughly half the addresses are covered and roughly half are not, which means the answer is per house rather than per town.
Where it does apply, the rule governs how the sander is set up: containment and a HEPA vacuum collecting dust where it is generated. We check the age of the house before deciding how the work is staged.

How custom stair installation runs
We measure the opening
Every riser, every tread, and how far out of square the whole thing is.A drawing, not a catalog page
The design is drawn and agreed before material is ordered.Material selected
Species matched to the floor where the two meet.Structure corrected
Squeaks, movement and out-of-level risers addressed before anything finished goes on.Treads, risers and skirt fitted
Each piece cut for its own position.Railing and finish
Handrail, balusters and newel posts to code, then finish.
What is included in a custom stair installation
A custom stair installation covers the measuring, the drawing, the material and the fitting of every finished part of the stair. The railing is drawn with the stair. Work on the walls around it, and changes made after the drawing is agreed, are not part of the stair quote.
Included
- Measuring every riser and tread, and how far out of square the opening is.
- A drawing of the stair, agreed with you before material is ordered.
- Hardwood for treads, risers and skirt board, supplied by us and matched to the floor.
- Correcting squeaks, movement and out-of-level risers before finished material goes on.
- Fitting each tread, riser and skirt board, cut for its own position.
- Handrail, balusters and newel posts built to the code adopted locally, then stain and finish.
Not included, or quoted separately
- A firm price before we have measured the stair in person.
- Painting walls or repairing plaster next to the stair. That is not part of the stair quote.
- Changes to the design after the drawing is agreed and material is ordered. Those are quoted again.
- Structural changes to the house around the stair, such as moving a wall or reframing a floor opening.
What changes the price of a custom staircase
The price is set after we measure the stair in person, never before. Three things move it most: how many steps there are, whether the stair is open on one side, and how much of the existing structure has to be corrected before finished material goes on.
| What changes it | How it moves the price | Example |
|---|---|---|
| Number of steps | Every step is a tread and a riser measured and cut for its own position, so more steps means more pieces and more fitting. | A straight flight of fourteen risers is fourteen slightly different treads, not one tread cut fourteen times. |
| Open or closed sides | A stair open on one side needs returned tread ends and a guard with balusters. A stair between two walls needs neither. | On an open side each tread is returned so the end grain does not show, and the balusters are set into the new treads. |
| Condition of the structure | Loose treads, separated risers and uneven step heights are corrected first. How much of that there is shows once the stair is open. | A stair that squeaks on most steps takes more correction than one that is quiet and solid under the carpet. |
| Turns, landings and winders | A straight flight is the simplest geometry. Landings, turns and wedge-shaped winder treads add layout and cutting to every piece involved. | A stair that turns a corner on winders takes longer to draw and fit than a straight flight with the same number of steps. |
| Species and railing design | Tread stock is thicker than flooring and its cost follows the species. The railing adds posts, rail and balusters, in wood or iron. | White oak treads with a wood rail and iron balusters is a different material list from red oak treads between two walls. |

Why homeowners hire Deco Hardwood Floor
Deco Hardwood Floor is owner operated: the person who quotes custom stair installation in University City is the person responsible for it, and the material comes with the labor in one number.
Material and labor in one number
We buy the flooring direct from the distributor and pass the store price through, so you are not sourcing wood on your own between quotes.
Samples come to your house
Samples and larger offcuts come to you, so the color gets chosen in your own light instead of under a showroom lamp.
Stairs and railings built in house
Treads, risers, handrails and newel posts are drawn and built by our own crew. Most flooring crews subcontract stair work or decline it.
The owner quotes the job
The person who measures your floor is the person responsible for the work. There is no salesperson in between.
Measured before it is promised
Remaining thickness is measured at the edge of a board before we say a floor can be sanded, and no price is firm before we have seen the room.
Told straight, including the limits
Vacuum extraction catches most of the sanding dust and not all of it. We tell you that before the job instead of after.

Questions about stair installation in University City
We are pulling the carpet off our stairs. Is there hardwood underneath?
Almost never a finished one. What is normally under stair carpet is construction grade lumber that was never intended to be seen. The finished stair gets built on top of it, which is a different job from refinishing.
Can you match the stairs to my existing floor?
Usually, and it gets tested on a sample rather than promised from a species name. Stair treads are thicker stock than flooring and can take stain differently.
How long does a staircase take?
Longer than customers expect, because each piece is measured and cut for its own position. We give you the schedule for your specific stair once it has been measured.
Do you do the railing too?
Yes. Handrail, balusters and newel posts, built to the code as adopted locally.
Can you tell me what my floor needs over the phone?
We can tell you what is likely, and this page is most of that answer. What we cannot do is quote a floor we have not seen, because remaining thickness and what is under the covering both decide the job and neither is visible in a description.
Do you bring the material?
Yes. We buy direct from the distributor and the material lands in the same number as the labor. Samples and larger offcuts come to the house so you choose in your own light.
My house is from the 1920s. Can the floor still be sanded?
Often, but it is a measurement rather than an assumption. Only the wood above the tongue can be sanded, and a floor that has been refinished twice already may have one pass left. We check at the edge of a board before quoting.
