Welcome to Stress-Free and High-Quality Remodeling. A great remodeling experience doesn’t happen by accident—it starts with choosing the right company that offers excellence through expert project consultants, professional designers, dedicated project managers, master installers, on-time project completion, and a 3-year project warranty. Our smooth, simple, and innovative approach ensures that every step of your remodeling journey is enjoyable, fulfilling, and frustration-free. From design to management to installation—we do it right. No exceptions. If you're ready to successfully complete your kitchen, bathroom, basement, or home remodeling project, schedule your in-home consultation with one of our friendly team members at 847-809-3355.

"Overall very happy with our experience with 4Ever Remodeling. They took our completely unfinished 1920s basement and created an in-law suite with extra-large bath. They were great at handling the City of Chicago permit process, which was one of my biggest concerns. Work included: Rebuilding basement stairs (sturdiest stairs I've ever seen). Adding a full bath with jetted tub, two-person shower, tile, all new plumbing including ejector pump. New exterior windows to comply with egress codes (really impressed with the exterior brickwork - you can't tell at all that any changes were made. They matched the grout and design perfectly). Installation of a large wet bar with dishwasher, shelving, quartz counters and cabinetry. Cabinets are very high quality. HVAC for basement and they extended the AC throughout first floor as well. Lighting, flooring, drywall, insulation etc. Highlights: Particularly impressed with their carpenter who did gorgeous, perfectly aligned work. Their designer, Magda was very helpful in guiding us and helping make selections (we've never done a project anywhere near this scope before). Communication was very clear and responsive. Workspace was immaculate at the end of every day. As with any project of this size there were a few nits: Their electrical team was slow to address a few concerns the inspector had and they disabled an outlet on the first floor. Granted, they were given an absolute trash mess of wiring to start out with. Also, the bathroom painter did not cover the tub when painting the ceiling, and I had to spend some time scraping flecks of paint off with a credit card. Those minor issues aside, I feel confident the project was done right, everyone that sees it absolutely gushes about the result, and I'm jealous that my in-law kitchen and bath are nicer than my own on our first floor! I'd definitely use 4Ever again (and in fact are considering a second project right now)."

"What can I say about Dan and crew? If there were six stars, I would have given them all of those! Our powder room job was also flooring for the hallway and laundry room, plus a utility sink. It was a total gut job in the bathroom. Dan could not have been nicer, quoted us a more than fair price and the job was finished in record time. He was very responsive to any questions we had (ok mostly me). Also, his workers (2) were fantastic. I'm not sure if I should name them, so I won't. They were efficient and professional, asked questions when needed and cleaned up the site and their work space (our garage) every single day. They treated our home with care, as well as our old appliances and new fixtures. We could not have been happier with all of it."

"1. Very fast to respond to the the request 2. The staff was exceptionally nice, explained what they do and how they work. 3. Scheduled an appointment with a 2 hr window. 4. Repair showed up on time. (Two people) 5. They examined the problem and gave me a quote (fair and reasonable) 6. They went to work and resolved the sewer backup issue. Then they went ahead and cleared all the pipes of sludge until the water ran clear. They explained the issue was food residue buildup from the garbage disposal. That made sense since we has done a lot of summer and fall canning and used the disposal extensively. 6. They did a excellent job, very courteous and explained everything along the way.

FAQs for tankless water heater installation projects in Downers Grove, IL

Professional flushing services for tankless water heaters run about $200 per visit. This essential maintenance procedure eliminates mineral deposits from critical components, particularly the heat exchanger. While homeowners can purchase DIY flushing kits for $50 to $100, professional service offers the advantage of thorough cleaning with proper techniques. Professional maintenance also includes inspection of additional components that might need attention.

Industry experts and manufacturers recommend annual maintenance for tankless water heaters, with more frequent service (every six months) for homes with challenging water conditions. This regular attention prevents efficiency losses and extends the unit's operational lifespan. Watch for warning signs like reduced water temperature, inconsistent performance, or system error codes that might indicate maintenance is needed sooner than scheduled.

Neglecting regular maintenance allows mineral scale to accumulate within your system, restricting water flow and reducing heating efficiency. This forces your unit to work harder, consuming more energy while delivering less satisfactory performance. Over time, this strain can lead to component failures, inconsistent water temperatures, and premature system replacement. Additionally, most manufacturers require documentation of regular maintenance to honor warranty coverage for major components.
