"I hired this company to lay wood flooring throughout the house, to refinish the stairs and to replace all banisters and railings. I couldn't be more please with how this project came out. The people that worked here were professional and did a phenomenal. Hands down, some of the best people I've worked with. They showed up on time, the quality of the work was fantastic and they left my house cleaner than when they started. I was so pleased with everything and everyone related to this job that I called them back to renovate my kitchen. They are the only company I will use going forward. I was lucky to find them. "

Tired of overpriced firms or no-show handymen? Your home is your life. Not just the next jobsite or work order. When it needs fixing or upgrading, you shouldn't have to choose between them.  Not every project needs a crew of 20. And not every job should be DIY. As a veteran-owned company, we take pride in getting the job done the right way the first time. Whether it's storm-repair siding, a fresh bath facelift, or that "I'll get to it later" room, we finish on schedule and on budget. No shortcuts, no excuses. Your home deserves more than a contractor. It deserves a partner.  Let's get that next project off your list.

FAQs for addition to existing structure building service projects in Algonquin, IL

Yes, you can add a bathroom on a concrete slab, but the crew will need to saw-cut the slab, trench in new supply and drain lines, and then patch the concrete without weakening the foundation. Working with an experienced plumber and concrete pro keeps the structure intact and helps the new bathroom pass inspections.

schedule covers planning, permits, framing, rough-ins, finishes, and punch-list items. 

Larger spaces or extensive plumbing and electrical upgrades can stretch the timeline, while a simple powder-room conversion may wrap up faster. Hiring licensed pros helps keep the schedule on track and the work up to code.

The best location depends on how your family uses the space. An upstairs bath keeps nighttime trips close to the bedrooms, while a first-floor powder room is handy for guests and everyday traffic. 

Think about where plumbing lines already run, how much square footage you can spare, and what layout changes fit your budget. A pro can map out the smartest spot and handle any code hurdles.

With the right planning, you can carve out a bathroom in almost any part of the house. A successful addition requires sufficient space, proper ventilation, and access to plumbing and electrical systems. Structural modifications and adherence to building codes are essential. 

This process demands careful planning and the coordination of specialized professionals who ensure that the new space meets all code requirements and functional needs.

Under specific conditions, adding an extra bedroom can boost home value more than adding a bathroom. Home value is driven by overall configuration, market demand, and functional balance. A new bedroom influences the property’s appeal in different ways, while an additional bathroom enhances living convenience. Evaluating the current layout and market trends determines the optimal choice for maximum value.
