TAP Construction makes it easy to turn your plans into a reality. We are helping people to get the most out of their homes by building custom additions, or improving any space, inside or out!

"After having a problem with a "reputable" contracting company, TAP Construction came through and began our addition. Todd was very professional, as well as his staff/contractors-a welcome change. Immediately, we saw a difference in workmanship and ethics. We would recommend Todd for any project and would use again if needed."

"Review for G&G Landscaping (G&G Landscape, LLC) – Owners Derek & Amanda Gardner, MHIC# 155902 In 2024, I hired G&G Landscaping to complete a patio and fence project at my home, totaling $44,000 ($9,800 of which was for the fence). While I was initially satisfied with the patio installation, the quality of their work quickly came into question. Just 11 months after completion, the patio began to sink in several areas, creating large and noticeable gaps between the pavers. This is extremely disappointing, especially considering that the project came with a 5-year craftsmanship warranty, which was a major reason I chose G&G over other (less expensive) contractors. I reached out to Derek Gardner through the contact information provided. He responded at first, apologized for the issue, and assured me that someone would come to inspect the patio by the end of that week. That was over two weeks ago—and no one has come, nor have I received any further communication. I’ve followed up multiple times by phone and email with no response whatsoever. It’s unacceptable that a patio of this cost and supposed quality is already failing in less than a year, and even more troubling that the company is now unresponsive and failing to honor their written warranty. If I could go back, I would choose a different contractor. I strongly caution others against hiring G&G Landscaping—they do not stand behind their work."

"This company went above and beyond for my wife and me. We wanted a balcony with steps but we had an HOA to go through. Shaun talked to my HOA several times and even visited the HOA property management company to drop off and speak to them about my build. His two workers showed up each day even on the weekend to get the job finished in a timely manner. The 2 man crew did a phenomenal job with keeping my lawn as nice as they could and even replaced the dirt and bricks they had to dig up for the posts. This was the best experience we have had in a long time with contractors and I thank Shaun and Maryland Remodeling &Design/Build for restoring my faith in contractors."

FAQs for addition to existing structure building service projects in Sparks Glencoe, MD

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.
