My business is a small business with only myself, the owner, and generally one or two helpers unless the job calls for more. Most of the work we do is done by us that way we can control the quality better. We will occasionally use a sub contractor for specialized trades, but we use the same trusted businesses every time! We do not accept credit cards at this time but checks or cash is fine. We are not doing any financing at this time so we take deposits when work starts and generally whatever is left is do at completion of project.

"Paul went above and beyond to help me out and did a great job on our porch. I had an issue with a previous contractor and he reassured me everything would get done. Just 2 days and it looks great! Thanks Paul! If anyone is looking for a reliable contractor i highly recommend Paul Baucco Construction."

As a leading general contractor in Lake and Ashtabula Counties, OH, we've built a reputation for quality work, friendly service, and competitive pricing.

"They were hired to replace a tub, fixtures, and put in tile surrounding the tub with a niche and 2 shelves. We also had them re route a vent pipe in a separate bathroom so that it is past the trap and not letting sewer gases into the home. We were given options for materials based on our budget and guided on who to meet with at the appropriate store to select our materials. The work was done within the timeframe we gave. They did an excellent job making the space beautiful and professionally done. They respected our home and cleaned up better than expected each day. Of course, there were unexpected issues that arose that were dealt with without concern such as having to shore up not plumb walls. The price wasn’t cheap but was reasonable. In all, they did an excellent job."

"Christian and his father were great! Christian contacted me the same day I put in my request through Angi. They came out the next day, were prompt, called before they came and when they arrived, and completed the job quickly but thoroughly! They did an excellent job! In the Spring, we will be asking them to come out again to install a new post and mailbox. I would not hesitate to recommend them to anyone!"

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