Initial Consultation
We start with a friendly conversation to understand your ideas, goals, and any special features you hope to include in the basement. Whether you’re thinking about a home office, entertainment space, or guest suite, we’ll help clarify your concept and answer all your questions.
Comprehensive Basement Assessment
Next, we assess your basement to understand its current setup. We check the structure, look at the plumbing and electrical wiring, and measure everything. This step ensures we’re fully prepared so the remodeling process goes smoothly and safely.
Custom Design Plan And Proposal
After the assessment, our designers create a plan based on your needs and budget. We’ll walk you through 3D renderings, room layouts, and finishes so you can imagine what your basement will look like. We’ll also give you a detailed estimate so you know the costs and timeline upfront.
Agreement And Project Confirmation
Once you’re happy with the design and budget, we’ll finalize everything in an official agreement. This step confirms all details and lets us set a start date for construction. By confirming all aspects upfront, we ensure there are no surprises, giving you peace of mind before construction begins.
Pre-Construction Planning Meeting
Before we start any work, we hold a pre-construction planning meeting to go over the logistics of the project. During this meeting, we review the timeline, daily schedules, access to the basement, and any preparation steps on your end. Our team is here to make sure everything is clear and convenient, minimizing disruptions to your daily life.
24/7 Communication
We understand that questions and ideas can come up at any time. That’s why you’ll have a dedicated project manager available 24/7 to keep you informed. From start to finish, if you have questions or need help, we are just a call away, ensuring a stress-free remodeling experience.

Very happy we made the decision to go with Deyan and his team at ILGCS. They were very responsive, fast, receptive to feedback, and ended up doing a fantastic job with the bathroom remodel. Would definitely recommend them.

Quick and honest communication from the estimate through entire process for a bathroom renovation. Crew was extremely polite and cleaned up as if construction hadn't happened. Reasonable price and delighted with the results.

Deyan and his crew took on our project after some difficulties with a previous contractor. He was so helpful in sharing details of what needed to be done and communicating clearly with his team and me. They did a great job finishing our basement, and we are very pleased with how it turned out!

During last January cold weather our pipes froze and we had damage on three levels of the house including drywall, flooring, painting and bathroom issues. We contracted with IL General Construction to fix everything. With any contractor you can only get three things. Those are quality of product/installation, service/reliability and finally, fair price. Usually you can get two of the three. With this family owned business we got all three. They even helped negotiate with our insurance carrier. There is always the intangible of comfort with your contractor. By the end of the process both my wife and I were well beyond satisfied with the entire work process. Suffice it to say that if asked we would only recommend this company to family, friends and anyone else.

Very responsive and did excellent work. They responded immediately to my request for service, showed up when they said they would and did the job well. Highly recommend.

Increased Moisture Or Dampness
If you notice mold, mildew, or a musty smell, your basement may have water issues. Remodeling the basement with proper waterproofing can address these concerns, improving air quality and preventing future damage, creating a safer, healthier environment.
Increased Energy Bills
An inefficient basement with poor insulation can lead to higher energy costs. A basement remodel offers the opportunity to improve energy efficiency by adding insulation, new windows, and energy-efficient lighting, helping you save on monthly utility bills.
Outdated Design
If your basement feels stuck in the past with old carpet, dingy walls, or poor lighting, it’s time for a refresh. A modern basement remodel can give your space a fresh look, adding modern finishes that enhance its functionality and increase property value.
Don’t let your basement sit there collecting dust; give it the upgrade it deserves.
