BASEMENT REMODELING

Chicago's Trusted Choice For Expert Basement Remodeling

An unfinished basement is the most underused square footage in your Chicago home. At Reliable Construction Group, we transform raw, underutilized basement spaces into fully finished living areas — family rooms, home offices, in-law suites, home gyms, and rental units — that add real, measurable value to your property.

We handle every phase of your basement remodel in-house: waterproofing assessment, framing, insulation, drywall, flooring, plumbing rough-in for wet bars or bathrooms, electrical, lighting, and finish carpentry. One team, one contract, one point of contact from start to finish.

Chicago basements come with specific challenges — high water tables, clay soil, freeze-thaw movement, and older drain tile systems. Our team has worked through every combination of these conditions across Chicago’s neighborhoods for over 30 years, so we know what to look for, what to fix, and how to build a basement that stays dry and comfortable for decades.

Complete Basement Remodeling
Services in Chicago

From open-plan family rooms to fully self-contained in-law suites, our in-house crew handles every trade under one roof — delivering a finished basement that is dry, comfortable, and built to Chicago code.

Basement Waterproofing & Moisture Control

Before we frame a single wall, we assess your basement for moisture intrusion, efflorescence, and hydrostatic pressure. We install interior drain tile systems, sump pumps, vapor barriers, and waterproof wall panels where needed — because no finish material will survive a wet basement. We build the dry shell first, then the finished space on top of it.

Framing, Insulation & Drywall

We frame basement walls using pressure-treated bottom plates and correctly sized studs for Chicago’s climate, install closed-cell or fiberglass batt insulation to code R-values, and hang, tape, and finish drywall to a Level 4 or Level 5 finish. Every wall cavity is treated for moisture resistance before closing.

Basement Bathroom Addition

Adding a bathroom to your basement dramatically increases its livability and resale value. Our licensed plumbers handle below-slab rough-in, ejector pump installation, and all finish plumbing connections. We also tile, install vanities, and complete every fixture hookup — a full bathroom addition with a single contractor.

Flooring Installation

Basements require moisture-tolerant flooring. We install luxury vinyl plank, engineered hardwood, porcelain tile, and carpet — selecting products rated for below-grade installation and installing moisture barriers beneath where required. We also handle concrete floor prep, self-leveling underlayment, and subfloor systems to eliminate cold concrete underfoot.

Egress Window Installation

If you want a legal bedroom in your Chicago basement, Illinois code requires a properly sized egress window. We excavate the window well, cut the foundation opening, install the egress window unit, waterproof the well, and obtain all required permits and inspections — converting your basement into legally habitable bedroom square footage.

Wet Bar, Home Theater & Custom Finish Work

We build custom wet bars with cabinetry, countertops, undermount sinks, and beverage refrigerator hookups. We also frame and wire dedicated home theater rooms with in-wall speaker rough-in, projector mounts, and blackout considerations. Every custom finish element is designed in-house and built by our own carpentry team.

Our 4-Step Remodeling Process

We have refined our process over 30 years so every Chicago homeowner knows exactly what to expect- and who to call – at every stage of their Kitchen Remodel.

Free In-Home Consultation

We visit your basement, assess existing conditions — moisture, ceiling height, mechanicals, and drain locations — and listen to how you want to use the space. We bring flooring and material samples and give you an honest assessment of what the project will realistically cost and take.

Design & Fixed-Price Quote

Our designers produce a detailed layout plan with material selections and a fixed, line-item quote. You approve every tile, fixture, and finish before we order anything. The price you approve is the price you pay – no open-ended estimates.

Permits & Project Scheduling

We handle Chicago Building Department permit applications for all plumbing, electrical, and structural changes. Most projects begin within 3–5 weeks of contract signing, with all materials staged and ready to go before your crew arrives.

Build, Inspect & Warranty

Our crew works with daily clean-up and a weekly progress update to you. After the final inspection, we do a walk-through together, address any punch-list items immediately, and issue your 2-year written craftsmanship warranty before we leave.

The Reliableg Difference

Chicago basements are not like basements in other parts of the country. The soil conditions, water table, and aging infrastructure in Chicago homes demand a contractor who understands the specific challenges — not one learning on your job. Our team has finished over 800 basements across Chicago and the northwest suburbs.

We start every basement project with a thorough moisture assessment before any framing begins, because the most common and costly basement remodeling mistake is finishing over a moisture problem instead of solving it first.

Basement Remodeling FAQs

Straight answers to the questions we hear most from Chicago homeowners considering a Basement remodel.

How much does a basement remodel cost in Chicago?
Basement finishing costs in Chicago depend on size, scope, and existing conditions. A basic open-plan finish — framing, drywall, flooring, and lighting — typically runs $25,000–$45,000. Adding a bathroom, wet bar, or egress window will increase the cost. A full basement remodel with a bathroom, custom bar, home theater, and egress bedroom generally runs $55,000–$90,000+. We provide a free, detailed fixed-price quote before any work begins.
A basic basement finish without plumbing typically takes 4–6 weeks. A full remodel with bathroom rough-in, egress window, and custom finish work usually runs 7–10 weeks. We provide a specific written timeline before we start — and we stick to it.
Yes. In Chicago, finishing a basement requires permits for framing, electrical, and any plumbing additions. Egress window installation requires a separate structural permit. We handle all permit applications and inspection coordination with the Chicago Department of Buildings. Permit costs are included in your fixed-price quote.
Before any framing begins, we conduct a full moisture assessment — checking for active seepage, efflorescence, hydrostatic pressure signs, and sump pump condition. We resolve any moisture issues first using interior drain tile, sump systems, or waterproof wall panels before installing any finish material. We will not frame over a problem.
Yes, with an egress window. Illinois building code requires a minimum window opening size for any below-grade bedroom. We handle the full egress installation — excavation, foundation cut, window unit, waterproofing, and permit inspection — to make your basement bedroom fully legal and insurable.
All basement remodeling work is backed by a written 1-year craftsmanship warranty. If anything we installed fails within the warranty period, we come back and fix it — no questions asked.
