Spindle Replacement in San Ramon, Done in a Day or Two
Spindle replacement in San Ramon is the job we get asked about most in the 1980s and 1990s homes around the valley: pull out the builder-grade oak or painted wood spindles and set iron balusters in their place, keeping the stairs, treads and usually the handrail. Most swaps take a day or two in an occupied home, and they are scheduled about a week after you approve the design (special-order styles can add time). You can price your baluster swap in about a minute with our estimator before anyone visits. Price it in a minute. Installed in about a week.
This page covers the spindle and baluster swap on its own. If you want a completely new stair railing, including cable or glass, see our interior stair railings page.
Why So Many San Ramon Staircases Still Have Oak Spindles
Census figures show about 19 percent of San Ramon's homes were built in the 1980s and another 17 percent in the 1990s, and roughly 40 percent since 2000. That is the era of the two-story entry foyer with a curved or switchback staircase, a stained oak handrail, square oak newel posts and turned wood spindles. Dublin is newer still, with about 69 percent of its homes built in 2000 or later, many with painted white spindles that chip and yellow over time.
The structure of those stairs is almost always sound. What dates them is the infill. Replacing spindles with iron balusters is the single biggest visual change you can make to a foyer without remodeling the stair itself, and it is a common first project after buying a home in Twin Creeks, Dougherty Valley or West Dublin.
What a Spindle-to-Baluster Swap Includes
- Inspection first. We check that the handrail is tight, the newel posts do not rock and the landing guard is at a safe height before quoting a swap.
- Removal. Each old spindle is cut out cleanly at the tread and pulled from the handrail, with drop cloths down and dust kept to the stair.
- Fitting. Iron balusters are measured and cut on site, one at a time, because every tread and every angle on a curved or switchback stair is a little different.
- Setting. Each baluster is epoxied into the tread and finished with a shoe that hides the old hole, then seated into the underside of the handrail.
- Spacing. Layout is set so every gap stays under the code limit before the first baluster goes in.
- Cleanup. We vacuum, wipe down and haul away every old spindle.
Iron Baluster Styles and Finishes
| Style | Look | Works best with |
|---|---|---|
| Plain square | Clean, modern, quiet | Updated foyers, painted newels, transitional homes |
| Single or double twist | Classic, a little texture | Stained oak rails in 1980s and 1990s homes |
| Single or double basket | Decorative, traditional | Mediterranean and Tuscan style homes common in the valley |
| Single or double knuckle | Simple accent at mid-height | Mixing with plain balusters for a pattern |
| Scroll or ornamental panel | Statement piece | Landings and lofts that face the front door |
Most homeowners mix two styles in a repeating pattern, for example two plain balusters and one basket. Common finishes are satin black, oil-rubbed bronze and antique bronze. Hollow iron balusters keep cost down; solid iron feels heavier and costs more. We bring samples to the free on-site measure so you can see them against your actual handrail.
Keep Your Oak Handrail or Replace It?
| Option | What changes | Typical installed range |
|---|---|---|
| Baluster swap | Spindles out, iron in. Handrail and newels stay; optional sand and restain | About $40–$70 per linear foot |
| New handrail + balusters | New handrail and newel posts plus iron balusters | About $60–$100 per linear foot |
| Full new stair railing | All-metal, cable or glass system | See interior stair railings |
If your oak handrail is solid and the right height, keeping it is the best value; a light sand and restain makes it look new next to black iron. Painting the newel posts white or black while keeping a stained handrail is another popular update. If the handrail is loose, too low or too wide to grip comfortably, we will tell you before quoting rather than put new balusters under a rail that should be replaced.
Code Checks We Make on Every Swap
Replacing balusters means the guard has to meet the spacing rules when we finish. On every job we check:
- Openings: a 4-inch sphere cannot pass between balusters, and the triangle formed by the tread, riser and bottom rail cannot pass a 6-inch sphere.
- Handrail height: 34 to 38 inches above the stair nosing, continuous for the full flight.
- Grip: a profile you can actually wrap a hand around.
- Landing and loft guards: some older homes have guards lower than current code allows. If yours is low, we flag it and give you options to raise it during the same visit.
A baluster-only swap usually does not change the structure of the stair, but rules vary by department, so we confirm with the San Ramon Permit Center at City Hall, or your own city or the County, before we start. Read more in our California railing code guide.

Spindle and Baluster Replacement Cost in San Ramon
A typical San Ramon foyer stair with a short landing has around 25 linear feet of railing. At about $40 to $70 per foot for a straight baluster swap, that is roughly $1,000 to $1,750; adding a new handrail and newels brings it to about $1,500 to $2,500. Curved stairs, ornamental or solid iron balusters, and restaining the handrail move the number up. Our stair railing remodel cost guide walks through more examples.

Why Choose Us for Baluster Replacement
Fitted One Baluster at a Time
Every baluster is measured and cut to its own tread instead of being forced to a standard length, which is what keeps the line straight on curved and switchback stairs. Each one is set in epoxy under a shoe so the old holes disappear and nothing rattles loose a year later.
Checked Against Code Before Day One
We lay out spacing so every gap stays under the 4-inch limit and confirm the handrail sits 34 to 38 inches above the nosing before any spindle comes out. If the landing guard is too low, you hear about it on the first visit, not at resale.
A Day or Two in Your House
Because the stairs and handrail usually stay, most swaps are finished in a day or two while you live at home. Installs are scheduled about a week after you approve the design, and every old spindle leaves with us.

FAQ
Questions, Answered
Straight answers on cost, code, permits and materials. Still unsure? Call and ask.
How long does it take to replace wood spindles with iron balusters?
Most straight baluster swaps take one to two days on site for a typical foyer staircase, and you can stay in the house while we work. Curved stairs, long lofts or a handrail restain can add a day. We schedule installs about a week after you approve the design.
Can I keep my oak handrail and just replace the spindles?
Yes, and it is the most popular option. If the handrail is tight, at the right height and comfortable to grip, we keep it and the newel posts, swap the spindles for iron, and can sand and restain the rail so it looks new against the black balusters.
How many iron balusters do I need per stair tread?
Usually two or three per tread, depending on the tread depth and the baluster style. The number is whatever keeps every opening under the code limit, so we lay out the spacing on your actual stairs during the free measure rather than guess from a photo.
Do I need a permit to replace stair spindles?
A baluster-only swap usually does not change the structure of the stair, but some building departments still want a permit when guards are replaced. We confirm with the San Ramon Permit Center, or your city or the County if you live elsewhere, before work starts.
How much does spindle replacement cost in San Ramon?
A straight swap that keeps your handrail runs about $40 to $70 per linear foot installed, so a typical 25-foot foyer stair is roughly $1,000 to $1,750. New handrails, curved stairs and solid or ornamental iron cost more. Our estimator gives an instant range, and the free on-site measure sets the written price.
