At R O Hutchinson LLC, we specialize in transforming spaces to meet your unique needs. Based in Upper Marlboro, MD, our expert team focuses on premier residential Remodeling. We excel in kitchen and bathroom remodels, flooring installations, and comprehensive basement renovations. With a strong reputation built on service, safety, and quality, RO Hutchinson LLC places utmost priority on customer satisfaction and delivering excellent workmanship from start to completion of every project. Our commitment is to understand the needs and expectations of our customers, communicate professionally, and get the job done right the first time.
"Our family home has always been clean and functional but after thirty years it had become more a picture postcard from the 1980’s than the warm inviting image we had in our mind. It was obviously time to update. Unfortunately, after talking with numerous contractors, it seemed we would have to reduce our expectations or spend more than we had budgeted to afford remodeling our “dining room, living room, kitchen” (and eventually bathrooms too!) project. While pondering our next move a family friend told us they recently had Rohan remodel their kitchen/living space and it looked great and was, they thought, affordable. After seeing for ourselves the quality of workmanship, the improvements to ‘flow and functionality’ and the overall aesthetic appeal, we decided to give Rohan a call. Boy are we glad we did! Upon meeting Rohan for the first time we were shown the same optimism, knowledge through experience, flexibility of thought and dedication to quality that would continue straight through to the end of our multi-week project. His proposal/estimate covered all our wants and needs while fitting within our budget. The job was a total re-do and from floors to walls to counters to cabinets to plumbing to electrics and all were handled by Rohan and his team with time honed skill. The work was done in a timely fashion without ever leaving us wondering where people were or what they were going to be doing each step of the way. Every eventual ‘architectural surprise’ was met with candor, budgeted creativity and a hearty “no problem!” In the end our home was transformed ergonomically, aesthetically and affordably into a beautiful space where family and friends gather in happiness and in harmony with their surroundings. If you are considering remodeling your home we urge you to give Rohan a call. Boy will you be glad you did! "

Our dedicated team works closely with each homeowner, providing personalized design consultations and transparent communication throughout the entire renovation process.

"Terrible experience. We contracted with Prime Custom (Kamil) to do a full bathroom and kitchen remodel in 2021 and we have had tons of issues. Their license # 2705166476 that they were operating under has been REVOKED as of May 2024. You can check this for yourself by going to the Virginia state website [*** Link removed ***] and entering the License # 2705166476. Yes, the name on the VA state website is different but they were operating externally as Prime Custom. As proof, I have attached a picture of the contract which shows the above License # , and Prime Custom's name. They are now operating under a different license # 2705173804 which I find highly unethical. I have already filed a complaint with the Virginia Department of Professional and Occupational Regulation and they will investigate if any laws were broken. Before considering doing business with Prime Custom, or any other contractor, please ensure that you look up their license number on the above Virginia State website. Summary of my experience: - Bathroom: The shower has developed a major leak which is going through the bathroom floor into the lower level. See pictures. I am contracting with another company to fix, which is going to cost thousands of dollars. Kitchen - It failed gas and safety inspections multiple times. To this day, I am concerned about the structural integrity of the load bearing wall in the kitchen and am contracting with another company to fix. Hopefully, this review can save others from the extremely frustrating experience that I have gone through."

Virginia-Based, Leading Kitchen and Bath Remodeler Since 1994 Class A Licensed, Insured, Bonded & Award Winning Vienna Showroom: 112 Church St. NW. Vienna, VA 22180 Herndon Showroom: 285 Sunset Park Dr. Herndon, VA 20170 With over 28 years of experience, My Kitchen and Bath has created some of the most exciting kitchens and bathrooms in the Washington D.C. area. We offer comprehensive remodeling services including full-service kitchen and bath remodels, custom cabinetry, granite, countertops, tile, carpet design, and customized plans and layouts. We know you are very busy, and don’t want your remodel to drag on and on while you have your life put on hold waiting for the project to draw to a close. That’s why we work quickly and efficiently to ensure that all of our projects are completed either on time or early. From the beginning stages of planning and preparation all the way through to the beautiful finished product, we are here for you. We will treat your home like it’s our home. We are committed to treating your job no matter how big or how small, as if we were working on our own home. The level of care and commitment to quality is our promise to every customer. We are excited to work with you and give you the care and attention you deserve!
"I really wanted to be able to leave a wonderful review, especially as there are so many good ones, which was partly why we chose My Kitchen and Bath-Vienna to do our small kitchen renovation. To start with the positives, HUGE shout out to Josh Turgut who had the grandest of vision for our tiny 1940’s kitchen which included some significant behind the wall design challenges. He designed us an awesome kitchen with everything we were looking for within our budget. We are very appreciative of his expertise, kindness, and overall professionalism. As for the project itself, the begin, middle, and end of our project was nothing but disappointing. Demolition left uncleared debris and some scratches on our glass topped washer as nothing was covered underneath in our basement (directly underneath our kitchen). The contractor was unprofessional, and clearly lacked technical ability and attention to detail. There was damage to cabinet fronts (which had to be argued with the project manager not just to be touched up with paint but replaced; won’t come in for weeks post project completion), grout poured in our back yard, and having to replacing a potion of our kitchen floor after having been completed blaming “it was walked on” (him and another worker rolled the fridge over the floor not even 24 hours after grout was complete). Our new dishwasher was scratched upon reinstallation with nothing reported to us about it. The construction manager UT seemed knowledgeable and when we were able to connect, seemed to want to ensure things were going as planned and to our satisfaction. The project manager Burak responded, mostly in haste, to all my inquires of questions and concern and came out to meet in person several times. It didn’t seem as if he had any specific information about our project, as there was no follow up after demolition regarding our back wall which we were unsure could be taken down and was a very important part of our kitchen renovation. A cabinet was also installed with built in trash cans that we did not request and were unable to replaced with our original request for a regular cabinet. I think it should also be noted, in my opinion, that the price of some of the renovation was over priced, being charged $600 to put in a water line for our fridge or the $550 for hardware to be installed (we supplied our own purchased hardware). Overall, we are left a well designed kitchen with some unsightly errors."

"STAY AWAY!!!! This Company cancelled the initial estimate on me 3 times making me drive 90 minutes to the property each time. They finally showed and gave me the typical hard sell "if you sign the contract today..." They gave us a quote so far over market value we should have walked away. But we agreed because of the "70 year history in the industry" We thought we were buying a service from a company with integrity. They took an immediate $18K deposit on a $55K project. I know, shame on me for agreeing to such an amount. We knew we were over spending, but... One month later, they simply cancelled the contract without explanation and without any work on the project. This contract was binding on us but, in their words, was not binding on them because "there's a clause in the fine print that allows them to cancel" THEY STILL HAVE OUR MONEY and I STILL NEED A ROOF Stay away from this company. No integrity No responsibility Unreliable Over priced Will take your money and keep it"

The cost to finish a basement is $18,400 for the average homeowner. However, this cost could be as little as $2,800 or as much as $34,500, depending on the basement size and the materials needed. If your basement is already outfitted with electrical and plumbing, expect the cost to fall on the lower end.
For example, the drywall cost for this project averages around $1,750, but other features, like hiring a plumber, cost between $45 and $200 per hour.
The cost to remodel a basement is between $12,100 and $33,400 for the average homeowner. The price you pay can be as little as $3,500 or as much as $50,200, depending on the size and condition of your basement and the type of remodel you're doing.
If you're doing a simple project like adding a home office to your basement, you can expect to pay anywhere from $500 to $3,000. However, if you're adding a bathroom, which is an extensive project, you can expect to pay between $6,600 to $16,500.
Damp proofing and waterproofing are both methods to help keep your basement dry. Damp proofing keeps soil moisture from entering your basement, which is helpful since your basement is underground. Waterproofing, however, keeps both soil moisture and liquid water out of the basement, which is essential, especially if you live in a wet environment. Because it’s more protective, waterproofing typically costs more than damp proofing.
Although homeowners often use the terms basement remodeling and basement finishing interchangeably, they are quite different terms.
Finishing a basement is the process of taking a basement space that is not habitable and adding elements to make it usable. This includes adding plumbing, flooring, and insulation.
Remodeling a basement means taking an already existing finished basement and changing it, often by adding or removing walls, adding plumbing, or changing the existing flooring.
The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in.
If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.
