"If you need a bathroom done, call someone else. We noticed water leaking outside the shower walls. We called. The first fix was them putting dry wall putty into a wet hole without finding the problem. My finger went right through the hole.They randomly half caulked one side of the shower wall panels.Days later, water continues to leak, and we lifted up the flooring to discover the flooring and subfloor had been soaked from the leaking shower. They come back. Cut out the drywall and caulk the entire shower that WAS NEVER CAULKED TO BEGIN WITH, we had to request they do this.Owner stated it wasn't mold, even though it wouldn't come off. Every time we had them come back, it looked worse. After they said they"fixed" everything, they did not replace the trim. Left paint on the floors, a screw from the new drywall is exposed after sanding and painting it and various pant chips. I've never seen a company rush to get a job done in all my life. We had to call them to come back and finish the initial job. We saved for years, YEARS FOR THIS REMODEL, and we SPENT THOUSANDS OF DOLLARS. Never again will I have a contractor come to my home."

For 18 years I was an Outside Sales Representative for nearly all aspects for the building industry. Part of my success was the understanding of how these products worked, were installed and repaired. I have been servicing, repairing and installing every aspect of a home and yard for as long as I can remember. I will work with every customer to meet their needs for their project. Pricing is always fair and negotiable. Since I have sold most everything we would need for your project, I can also help you get the materials at a great price.

FAQs for addition to existing structure building service projects in Belvidere, 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.
