Good quality craftsmanship is what we deliver and nothing is more important to us than your satisfaction and referral. 10 employees, billing procedures depend on the job, free estimates.We service the Northern suburbs of Chicago & Southern Wisconsin.

"Remodel went extremely well even with material delays (not ordered through Rowe construction.) They were able to pivot and work on different areas of this extensive remodel. This crew showed up every day and notified us if they were not going to come or if they were delayed.They also pointed out and/or were able to troubleshoot areas of design that wouldn’t look aesthetically pleasing. In addition, they cleaned up the interior each day and regularly picked up construction waste placed in the garage during this process."

Formerly know as G & G Furniture and Cabinet Restoration - Same Ownership since 1976 - We specialize in Refacing/Painting & Restoration of cabinets. All of our cabinets include custom doors, stain colors, paint colors, and finishing options. We also specialize in full Kitchen & Bath Remodeling, Counter Tops, Interior Doors, and all trim including crown molding.Tell us what you want to spend, and we will work out a plan to meet your budget.

"We researched several kitchen restoration companies and finally selected 3 of them to give us estimates for painting our outdated oak cabinets in the kitchen and master bathroom. The price ranged widely among the 3 companies. One estimate was extremely high. GG Kitchen Restorations was the cheapest estimate however, once we had each company come out and had them explain what they were going to do it was very evident that GG Restorations was going to be a one-stop shop for us to get everything done as we needed and with high quality workmanship. We did have a couple of extra small issues in the cabinets that needed to be fixed prior to the painting prep could start and the other 2 companies would either charge us a huge amount to do a drastic re-design which really wasn’t needed or said they wouldn’t do that type of work and left it up to us. GG Restorations was more than willing to help us get past these small barriers and get our dream kitchen to our specifications at a reasonable cost. Frank and his team were great. Frank is very pleasant and fun to work with and he takes the time to really get to know what you want. Chris and Tim, that did the work in the house, did excellent work, and they never left a mess. Our kitchen and bathroom look great and what a transformation from old to a modern look. We highly recommend GG restorations to anyone."

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