Custom Stairs in Buffalo Grove, IL
Stairs take more abuse than almost any other part of a home. Every person in the house uses them multiple times a day, every day.
When treads start to creak, risers crack, or railings feel loose in your hand, it is not just annoying, it is a safety issue worth taking seriously.
Buffalo Grove Carpentry builds, repairs, and replaces stair components for homeowners throughout the northwest suburbs.Treads, risers, newel posts, and wood railings, built to fit the existing staircase and hold up through years of daily use.
What Custom Stair Work Involves
Stair work falls into two broad categories: building new stairs and replacing or repairing existing components.
Replacing stair treads and risers is the most common request. Treads are the horizontal surfaces you step on. Risers are the vertical faces between them. Both can be replaced individually or as a full set without touching the underlying stringer structure.
Replacing or repairing railings involves the handrail, balusters, and newel posts. A handrail that wobbles, balusters that are loose or missing, or a newel post that has shifted at the base are all fixable without rebuilding the entire staircase.
Building new stairs from scratch involves calculating the rise and run, cutting stringers, and building the full stair assembly. This comes up most often in basement finishing projects where stairs to a newly finished lower level need to be built or upgraded from a basic construction staircase.
Refinishing existing treads involves sanding back worn or damaged wood surfaces and finishing them with a new stain or clear coat to restore their appearance.
We work with hardwood, pine, and poplar for treads and risers, and match the species and profile to what is already in the home where possible.

When You Need Stair Work Done
Stair problems tend to get ignored longer than they should because the stairs still function even when they are in poor shape. Here are the signs it is time to call:
- Treads that creak loudly or feel soft underfoot
- Visible cracks, splits, or surface damage on treads or risers
- A railing that moves when you grab it
- Balusters that are loose, missing, or damaged
- A newel post that has shifted or pulled away from the floor
- Stairs that were finished quickly during construction and never upgraded
- A basement staircase that does not match the quality of the rest of the home
In Buffalo Grove homes of this age, basement stairs are often the weakest link. They were built to code during construction but with minimal materials, and many homeowners have been meaning to upgrade them for years.
Why Stair Problems Happen
Stairs take constant impact and stress. Over time, that adds up.
Creaking treads usually mean the tread has separated slightly from the riser or stringer below it. Every step flexes the joint and the creak is the sound of wood rubbing on wood. It is fixable but it does not fix itself.
Loose railings are almost always a fastening problem. Railings secured only to drywall instead of into wall framing or structural blocking will work loose under repeated lateral force. This is a safety issue, not just a cosmetic one.
Cracked or split treads happen from years of impact, combined with the expansion and contraction that comes with Illinois seasonal humidity changes. Solid hardwood holds up better than pine over time, but both eventually show wear.
Wobbly newel posts are usually caused by the base connection loosening over time. A properly reinforced newel post connection lasts the life of the staircase. A poorly done one starts to move within a few years.
Repair vs. Replacement
Repair makes sense when:
- Only a few treads or balusters are damaged and the rest of the staircase is solid
- The railing just needs to be refastened or reinforced rather than replaced
- The wood is in good shape but needs refinishing to look right again
Full replacement makes more sense when:
- The treads are worn through, heavily damaged, or the wrong species for the look you want
- The railing system is outdated and a full upgrade makes more visual and practical sense
- You are finishing a basement and want the staircase to match the quality of the new space
- The existing materials are low quality and will need replacing again in a few years anyway
We will look at what you have and give you a straight answer on the best approach.
What Affects the Cost of Custom Built-In Shelving
Frequently Asked Questions
Can you replace stair treads without replacing the risers?
Yes. Treads and risers can be replaced independently. If only the treads are worn or damaged, we can replace those and leave the risers in place, or vice versa.
What wood species works best for stair treads?
Hard maple, red oak, and white oak are the most common choices for durability. They hold up well under daily traffic and take stain evenly. Pine is less expensive but softer and shows wear faster. We advise on the best option for your budget and the look you are going for.
How do you fix a creaking stair tread?
The fix depends on what is causing the creak. From above, we can add screws through the tread into the riser or stringer. From below, if the underside of the stair is accessible, we can add blocking or adhesive to close the gap that is causing the noise. We assess from both sides before recommending the approach.
Can you match the existing wood species and finish on my stairs?
Usually yes. We source wood to match the species already in the home and finish to match the existing stain or clear coat as closely as possible. An exact match depends on how the existing finish has aged, but we get as close as the materials allow.
Do you build basement staircases from scratch?
Yes. If you are finishing a basement and need a proper staircase built or an existing basic staircase upgraded, we handle the full job including stringers, treads, risers, and railing.
