Big Bro Hardwood is an owner-operated stair contractor serving Northbrook, IL. We refinish, repair, and install stairs, all under one roof. Stairs take more daily wear than any other surface in the house, and in many of Northbrook’s established mid-century and Colonial-style homes, there is original oak or maple hiding under carpet, a runner, or layers of old paint that is absolutely worth uncovering and saving.

We sand and refinish worn treads and risers, tighten loose railings, balusters, and newel posts, fix squeaks at the source, and match the wood to your existing floors. When a staircase needs more than refinishing, we install new treads or build a custom staircase from scratch. Call us for a free in-home estimate, typically scheduled within 24 hours, across Northbrook and nearby suburbs.

Why Hardwood Stairs Installation for Northbrook Homes

Hardwood stairs are a smart choice when you want a stair system that looks clean, feels solid, and can be restored instead of thrown out. For many homeowners in the Northbrook area, the best move is not full replacement but the right mix of stair repair, refinishing, or stair installation based on the condition of the existing staircase. If the core structure is still structurally sound, well-planned work can improve safety, restore beauty, and protect the value of the property.

Built for Daily Wear. Quality hardwood stairs are made for everyday use. When the surface starts to show wear, the wood can often be repaired or refinished instead of replaced.
Can Be Restored if Damaged. Many stairs do not need a full rebuild. A focused stair repair Northbrook project can fix loose parts, worn stair treads, damaged risers, and weak railings before they become a bigger problem.
A Better Match for Hardwood Floors. A wood staircase usually looks more complete when it connects visually to nearby hardwood floors. This is especially important in open residential spaces where the stairs are always in view.
Improves Safety and Function. Solid handrails, stable stair railings, and secure steps make the staircase safer to use. Good repairs also help prevent future damage and reduce the risk of a safety hazard.
Works for Repair, Refinishing, or Installation. Some stair projects need refinishing. Others need repair services or full stair installation Northbrook homeowners can rely on for a cleaner update. The right solution depends on the condition of the staircase.
Great for Style Updates. A refreshed staircase can change the feel of the whole house. Updated wood steps, cleaner railings, and a finish that matches the rest of the home add natural beauty without losing function.
A Cost-Effective Long-Term Choice. When the core structure is in good shape, restoring hardwood is often more cost-effective than full replacement. It also helps homeowners protect the value of the property with a more durable finish.

Our Stair Refinishing, Repair, and Installation Process in Northbrook, Illinois

Our process is built to make stair projects easier for homeowners who want clean work, clear steps, and no confusion about what happens next. Whether the job involves stair repair, dustless stair refinishing, or full stair installation Northbrook homeowners can trust, we start with the condition of the staircase and build the right plan from there.

Timeline at a glance for stair installation and refinishing:

12 to 14 steps: 2 to 4 days
12 to 14 steps + railings: 4 to 7 days

Measure and Plan

We start by looking at the full staircase, not just the visible wear. Our team checks the stair treads, risers, handrails, and stair railings to see whether the job needs repair, refinishing, or staircase installation. This first step helps us build customized solutions for your specific needs and explain the entire process with clear communication.
Protect the Home and Prep the Area

Before work begins, we protect the surrounding space and prepare the surface for the next stage. For residential stairs, good prep matters because it helps limit mess and keeps the work area safer during installation or refinishing. This is where our local expertise and reliable service make a difference for lived-in homes across the Northbrook area.
Handle Repairs First

If we find loose parts, worn edges, squeaks, or other structural issues, we address them before finish work starts. A proper stair repair in Northbrook may include wood stair repair, stair handrail repair, stair nosing replacement, stair post replacement, staircase spindle replacement, or stair riser replacement. Taking care of these repairs early helps prevent future damage and reduces the chance of a safety hazard.
Sand, Refinish, and Restore

When the existing hardwood stairs are still usable, we move into stair refinishing. This step may include sanding the worn surface, refinishing stairs, stair tread refinishing, refinishing stair railing, or refinishing wood banister sections that need a cleaner look. The goal is to restore the natural beauty, improve visual appeal, and create long-lasting results without replacing more than necessary.
Install or Replace What Is Needed

Some stair projects need new parts instead of surface work. We can complete stair installation, hardwood floor installation on stair systems, hardwood flooring on stairs installation, wood stair tread replacement, handrail replacement, or updates to a custom staircase that needs a better fit for the home. We use high-quality materials and focus on quality craftsmanship so the finished stairs look right and feel durable under daily use.
Final Check and Walkthrough

At the end of the project, we review the completed work with the homeowner and confirm that all finished areas are ready for use. This final check gives you a chance to look at the staircase, ask questions, and make sure the work matches the approved scope. It is also where our experienced team provides support and closes the job with the kind of professional detail people expect from stair services in Northbrook.

Why Northbrook Homeowners Trust Big Bro Hardwood for Stair Refinishing, Repair, and Installation

Stairs take more daily punishment than almost any other surface in the house. Choosing the right contractor means getting an honest assessment upfront, careful prep before any finish goes down, and a clear scope so nothing gets missed. Here is what sets us apart for homeowners in Northbrook and nearby suburbs.

Stair Parts and Safety First

Before we talk about stain colors or finish sheen, we look at how the staircase is holding together. We check every tread, riser, handrail, baluster, and newel post for wear, looseness, and anything that could become a real hazard. Tightening a wobbly railing or re-securing a creaking tread at the stringer is not a finishing detail – it is the foundation the rest of the work depends on. We handle structural issues first, before any sanding or coating begins, and we flag anything that needs attention for safety or code.

New Stair Parts Blended With Existing Woodwork

Wood ages differently in every home, and new material rarely matches old material straight off the shelf. When we bring in replacement treads, balusters, handrails, or posts, we look at species, grain pattern, profile, and how the wood takes stain before we commit to anything. Test staining on actual treads gives us a far more honest read than a color card. We will tell you when a close match is realistic and when it is not, so there are no surprises once the finish dries.

17+ Years, Owner-Operated

Big Bro Hardwood has been doing this work since 2009, and the company is still owner-operated today. The person responsible for the quality of your project is the same person scheduling it, showing up for it, and standing behind it. Over 500 projects across 30-plus suburbs have come from that approach, and roughly 80 percent of our work comes from referrals. For Northbrook homeowners, that means you are dealing with someone who has a real stake in getting it right.

Dust-Controlled for a Cleaner Home

Sanding stairs in a lived-in home creates real dust, and we take that seriously. We use dust-controlled sanding and protect the surrounding space throughout the refinishing process. Most homeowners in Northbrook can stay in the house during the work, and we plan the coating schedule around your staircase so access is disrupted as little as possible. The goal is to leave your home cleaner than the typical contractor would, not just the stairs themselves.

Railings and Handrails Coordinated With the Steps

A staircase is one connected system, and finishing only the treads while leaving the railings and balusters mismatched rarely looks right. When railing work is part of the project, we coordinate the repair, replacement, stain color, and finish sheen across every component – handrails, balusters, newel posts, and nearby trim included. The result reads as a single, intentional project rather than a collection of updates done at different times.

Finish Selected for Stair Traffic

Stair treads wear hard and fast, especially along the center run, the nosing edge, and wherever hands contact the rail. We use low-VOC Bona and Loba finishes and choose the specific product, sheen level, and coat count based on the wood species, the household’s traffic, and how the staircase is used day to day. Northbrook’s cold winters and warm summers create real seasonal wood movement, and getting the finish system right from the start means it holds up longer and stays easier to maintain.

What We Handle on Northbrook Staircases

A staircase can be a quick refresh or a full rebuild, and most people are not sure which theirs needs until someone actually looks at it. Usually it is less work than they expect. Here is the stair work we do most in Northbrook homes:

Solid wood stairs hiding under old carpet or a runner. Many of the established single-family homes in Northbrook, particularly the Colonials, ranches, and split-levels built between the 1940s and 1980s, have original oak treads that have been carpeted over for decades. We pull the carpet, check the wood underneath, and give you a straight answer on whether refinishing makes sense or whether a tread or two needs replacing first.
Matching refinished stairs to your existing floors. In a lot of Northbrook homes the floors and stairs have aged at different rates and faded differently, so a real color match comes from test staining on the actual treads, not from holding a color card up to the floor. We are upfront when a close match is realistic and when it is not.
Squeaks, loose handrails, and wobbly balusters. Split-level and multi-story homes in Northbrook put a lot of daily traffic on their stairs, and over time treads work loose, newel posts shift, and handrails develop play. We fix the problem at the source, re-securing treads and posts at the stringers and old fasteners, rather than covering the movement from the top.
Builder-grade stairs in newer homes and townhomes. Northbrook also has a solid share of newer construction and attached townhomes, where stairs were often finished with basic builder-grade treads or left carpeted. If you want to upgrade to hardwood treads, we can install new ones, match them to your flooring, and finish everything consistently.
Condo and townhome stairwells. For Northbrook homeowners in attached or higher-density properties, stair work sometimes involves HOA material or finish guidelines. We work within those constraints and can help you understand what the scope of the project will look like before anything is confirmed in writing.
Railing, baluster, and newel post replacement. Whether a post is too far gone to tighten or a homeowner simply wants to update the look of an older staircase, we handle baluster and newel post replacement as part of a refinish or as a standalone repair. Wood species, profile, and finish are all confirmed before we start so the result ties in with the rest of the home.

Not sure if your staircase needs a refinish, a few targeted repairs, or something more involved? That is exactly what the estimate is for. We look at the whole staircase, tell you what we find, and point you toward the smallest fix that actually solves it. We will not push a full rebuild when a couple of tread replacements and a good sand-and-finish will do the job.

Dan Melnikovas with Big Bro Hardwood did a great job refinishing our hardwood floors on our entire first floor! We highly recommend him for any refinishing projects.

We are incredibly happy with his work. His pricing is competitive, he is reliable, he showed up on time and completed our work in the timeframe we agreed upon.

We wanted to transition from a mid-tone oak with red undertones to a rich dark chocolate-toned floor with no red undertones, and we achieved just that.

Dan was diligent in preparing multiple samples for us prior to starting. We narrowed down our stain choice based on the samples. Then, after sanding down our existing floor, he meticulously mixed three sample stains on our actual floor to see how the color would take since each type of wood absorbs stains differently. This was a critical step for us. We never felt rushed. We were able to observe the stain colors with various finish/sheen levels in different lighting in our home prior to making our final selection.

We are thrilled with the results! Dan is not only extremely professional and talented, but he also is AMAZING when it comes to keeping the work site clean! The dustless system Dan used ensured our home was impeccably clean during the sanding process.

Excellent work!

Frequently Asked Questions

My Northbrook home has oak stairs that were covered with carpet for decades. Are they worth uncovering and refinishing?

Very often, yes. Many established Northbrook homes have solid oak treads hiding under carpet or a runner, and they are usually in better shape than homeowners expect. We pull the carpet, inspect every tread and riser honestly, and tell you what can be sanded and refinished versus what needs a replacement tread or two. If the wood is sound, refinishing it is almost always more cost-effective than installing new treads, and the result is far more durable than carpet in a high-traffic area.

Northbrook winters are hard on wood. Does seasonal moisture movement affect stairs differently than floors?

It does, and it matters here. The humidity swings between a dry Illinois winter and a humid summer cause wood to contract and expand, which can loosen treads, open gaps between risers, and make stairs squeak over time. We account for that movement when we fasten treads and apply finish. Using a low-VOC, flexible finish like Bona or Loba also helps the wood handle seasonal shifts without cracking or peeling as quickly as older oil-based products.

My Northbrook split-level has a short, steep stair run between levels. Can that be refinished or fitted with new treads?

Yes, and we do this regularly. Split-level layouts often have tighter, steeper runs with narrower treads than a standard staircase. We measure carefully before we quote anything, because fitting new treads or sanding close to walls and tight corners takes more time than an open staircase. The work is very doable; it just needs accurate measuring up front so there are no surprises on the day we show up.

A lot of Northbrook homes have maple floors. Can maple stairs be refinished to match?

Maple stairs can absolutely be refinished. The honest part is that maple is a dense, closed-grain wood that absorbs stain unevenly, which makes hitting an exact color match tricky. We always do test stains on the actual treads before committing to a finish, and we will tell you upfront how close a match is realistic given how the existing floors have aged. If a perfect match is not achievable, we say so before we start, not after.

How do I know if my stairs need refinishing, repairs, or both before any work starts?

We look at both before recommending anything. Squeaks, wobbling railings, and loose balusters are repair issues that need to be fixed at the source first, whether that is old fasteners, settling stringers, or worn newel posts. Refinishing over a structurally weak staircase does not solve the underlying problem. Once repairs are solid, we assess the surface condition and tell you whether sanding and a new finish will do the job or whether a tread or riser needs to be replaced entirely.

What does stair refinishing or installation typically cost for a Northbrook home?

Cost depends on several factors: the number of steps, the wood species, how much repair work is needed, and how much railing, handrail, and baluster work is involved. Matching an existing floor stain and any custom or curved work add time and cost as well. You can use our cost calculator to get a ballpark figure, and then we follow up with an itemized estimate after we see the actual staircase. Nothing is finalized until you have seen the full breakdown in writing.

Can I stay in my Northbrook home while stair work is being done?

Usually yes. There will be noise and some dust during sanding and prep, and we use dust-controlled sanding to keep the mess contained. If the staircase is the only way to reach an upper floor, we plan the work and finish drying times around that so you are not cut off. We protect the surrounding floors and walls throughout the project. Most Northbrook homeowners stay home without any real disruption beyond a few hours of noise on sanding days.

My railings and balusters are wobbly. Do you handle that separately from refinishing, or is it all part of one project?

We handle it all together, and that is usually the smarter way to do it. Loose railings and balusters get tightened or replaced at the source, not just glued from the surface. If a newel post is shifting because of an old fastener or settling, we fix it properly before any finish goes on. Combining repair and refinishing in one visit saves time and avoids disturbing a fresh finish later. We also flag anything that does not meet current handrail or baluster spacing standards so nothing gets missed.
