"We were so happy with our bathroom remodels done in December by Century Bathrooms and Kitchens. From the start we were really impressed with Daniel and Erika and their friendly, down-to-earth demeanor, and their intentionality to listen to our thoughts and show us the overwhelming options. They were great at communicating throughout the whole project, very knowledgable and thorough. Their work crews were friendly, professional, amazingly clean, conscientious, hard-working, and detail-oriented in every regard of their work. They were originally scheduled to start the work after the new year, but in the end they were able to bump up both of our bathroom remodels to the 3 weeks leading up to Christmas, and they blew us away with how quickly they were able to get the projects completed. Our bathrooms are beautiful, and we really couldn't be happier. Highly recommend Century Bathrooms and Kitchen."

KBA Kitchen and Bath: Transforming Homes with Excellence for Over 25 Years. Proudly Serving Fairfax County and Fauquier County.

"We would like to say thank you to KBA Kitchen & Bath Design & Build for a great job remodeling our two upstairs bathrooms. The two bathrooms were completely renovated in 5 weeks, but it could have been finished even sooner if we hadn’t selected a premium option for our shower glass enclosure. The entire project was started and finished between January 21, 2025 until February 28, 2025, which included the crew working two Saturdays, which shows their dedication in getting the job done. We were very impressed with KBA over the entire project! Specifically, we were impressed at how smooth and efficient the entire process was. It was seamless – from the initial consultation to the execution of the job. The designer, Anna, was very thorough and helpful in sketching the designs of new bathrooms and offering advice on recommended materials for the bathroom, to include going above and beyond in helping us choose just the right paint colors to perfectly blend with our newly installed bathroom accessories. Anna and Ervin both made after hour visits to provide their insight on color schemes and where bathroom accessories should be installed and look best. The lead project manager, Ervin, was always there to answer our questions, and he went out of his way to always ensure we were happy customers! Ervin also visited on many occasions to give us updates on project progress and keeping his crew updated on any changes. The installation team always showed up on time, left the work area clean, and went above and beyond to make our design a reality. Anna, Ervin and the crew were always very friendly, professional, and helpful throughout this project. We couldn’t be happier with the outcome as we absolutely love our bathrooms! We highly recommend choosing KBA for your next home project!"

Prime Custom Kitchen and Bath has been transforming Northern Virginia homes with exceptional remodeling services, offering complimentary in-house design and architectural expertise. From stunning kitchen and bathroom renovations to comprehensive basement remodeling and home additions, we handle every aspect of home improvement with meticulous attention to detail. Our dedicated team works closely with each homeowner, providing personalized design consultations and transparent communication throughout the entire renovation process. With our skilled craftsmen, certified designers, and experienced project managers, we deliver sophisticated, high-quality renovations that enhance both the beauty and value of your home.

"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."
