"This company, 12 Figure Consultations, came to my house and gave me a quote. Simple job, rake up all the sticks, take up the old mulch and put down the new. I gave them deposit. When they returned for the job, they did half of it, and then said they wanted more money than the original proposal to finish it - 2 times more. When I disagreed to pay 2 times more money, they started arguing with me, telling me I am liar, and behaving aggressively that I feared for my safety. Then his partner was following me around my yard and telling me he liked me and asking if I liked him! I was very afraid for my safety and I told them to just go away, because not only I was afraid for my safety, but their shoddy business practices so disrespectful, give one price, do half the job, then demand more money than the original to finish. I told them take their trailors and just to leave but they wouldn't. Finally I started raking it myself, and then I paid them the more money just to get them to go away. When they drove away, the workers skidded his tires in the grass in my yard and went speeding down the street. Then he drove around the street 3 times. I still fear for my safety and even afraid to write this review."

Misha's Home Improvement, Inc., has been in business for more than 16 years and all of our employees are skilled European craftsman. Call us for your entire wood and ceramic tile flooring needs!

"After having gone through four contractors who made big promises of written estimates which never materialized, my expectations of this company were pretty low. But when I reached out to Misha's Home Improvement I received a prompt and courteous reply. We made an appointment to meet at my house. Misha arrived at the appointed time (to which I arrived late) he walked up to meet me, holding a clipboard and measuring tape in hand. We shook hands and I realized right away that I was dealing with someone of a higher caliber. When we walked through the house I stated my requirements only partially whereupon Misha offered ideas and options. Every room. Methodically. Misha took measurements and we parted company. I had no appreciation for how much information he was taking in during our visit. A few days later a detailed estimate landed in my inbox. Room by room. Item by item with materials and labor costs and a detailed drawing of the entire layout of the home with precise measurements. No BS. I was impressed. We agreed upon a start date and a pattern emerged. This guy and his extraordinary team of guys came to the house every day (sometimes on weekends) and proceeded to embark on a Whole House renovation. Craftsmen all. Courteous and respectful to a man. Windows, bathroom reno, kitchen reno, recessed lighting. wiring fixes with attention to code, basement tile, patio doors, drywall repair, custom closets. Change orders written and agreed upon - in advance. No surprises in our agreements or fees. In fact, where warranted Misha refunded me for materialis/labor that were not needed. Misha and the guys have completed the job and I have to say that I will truly miss them. True craftsmen. I will absolutely recommend this company of men and the man who runs this enterprise. I got very very lucky."

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