"We recently hired this company to remodel our kitchen and bathroom, update our living room flooring, and refinish our staircase. Overall, we’re very happy with the results! Kitchen and Bathroom Remodel: Both spaces turned out beautifully. The team helped us select materials that fit our style and budget. The kitchen feels more functional and modern, and the bathroom looks refreshed with the updated fixtures and tile. Living Room Flooring: The new floors look fantastic and completely change the feel of the space. The installation was clean and precise, and they made sure everything was done right. Stairs: The staircase update tied everything together nicely. They replaced the old steps and railing, giving the space a much-needed facelift. The team was professional, communicative, and stuck to the timeline and budget we agreed on. We appreciated their attention to detail and the effort they put into making sure we were satisfied with the work. If you’re looking for a reliable company for home renovations, I’d recommend giving them a call. They did a great job on our project!"

Owner operated full service design, build & remodeling company. We specialize in custom homes, kitchens, bathrooms and whole house renovations. What makes us successful and one of the most profitable boutique companies is, excellent communication skills and having the owner on job site!!!

"It can be so stressful to find trustworthy companies that do high-quality work. Here’s why we have trusted Ultimate Remodel with our kitchen, bathrooms, basement, and office renovations for the past eight years. - Everyone, from Tunch to the crew, takes pride in their work. They pay attention to detail and go above and beyond. For example, in our most recent project, we had old baseboards that were a mess from the previous owner, but that were outside the project area. The crew sanded and repainted the baseboards, making our house blend in with the freshly renovated area. - Tunch provides his expertise in design, while matching our needs and visions for the space. He provides insight about changes that could impact our house’s value and makes recommendations for efficient use of space based on his extensive experience, but ultimately lets us choose the final product. For example, he made several suggestions to our laundry room plans that greatly improved the utility of the space. - Every project comes with unexpected challenges. What keeps us coming back to the crew and Tunch is the small number of issues that arise, and the ease of fixing the issues that do come up. Home renovation is stressful, and it’s so important to feel like your contractor is working with you towards a great final project, compared with nickel-and-diming you based on reasonable requests. I’ll also add that Tunch has kept members of his crew around for years, and I appreciate the expertise, consistency, and experience that comes with that. I highly recommend Ultimate Remodel."

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!"

Our team is driven to meet your needs with professionalism, creativity, and efficiency. Established 2005. Owner: Jonathan Perez Office Manager: Paige Marie Campbell Project Manager: Jefry Perez

"Basement Project We absolutely love our new basement! I was very nervous when selecting the contractor for this job. I interviewed three contractors for the job, all seem very decent, but what set Best Home apart was Jeff Segovia. He designed the whole layout of our basement (we love it) and oversaw the entire project from beginning to end. The construction crews were very polite and friendly. Best Home did an excellent job and very flexible with many changes I had and they completed the job on time (took 3 months and exactly 1 week)which was amazing. I am actually hiring them again for additional projects. I highly recommend Best Homes!"

Second story addition building services FAQs

Many homeowners find adding a second story a worthwhile investment. It significantly increases their home's value and provides more living space to enjoy. It’s especially beneficial for homeowners with a limited lot size who want to add square footage without building out. 

The time required to build a second story depends on the size and complexity of the project. While most additions are completed within two to six months, some larger or more intricate designs may take up to a year. The permitting process, weather conditions, and material availability also affect the timeline.

Your budget, location, and lot size will determine if it’s best to build up or out. If you live on a lot with limited space, building up allows you to add square footage without taking up additional ground space. Building out is often best if you live in an area with zoning restrictions or want to live in your home while it’s under construction.
