We offer complete roof replacements, sunroom installation, and additions. We are an exterior remodeler specializing in James Hardie fiber cement siding, vinyl siding, cedar siding, Sunrooms, 3 Season Room and more!

"Ohio Exteriors completed a three-season room that met all of our expectations. The office staff was responsive, and they provided a custom design that met our needs, particularly with the window options and slope of the roofline. The crew paid attention to details and adjusted well to the challenges that popped up along the way. The work was completed in a timely manner, and the site was kept clean throughout the project."

FAQs for addition to existing structure building service projects in Baltimore, OH

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.
