"Eco Power Works did a great job on my kitchen and bathroom renovation ! Daryl and John were very patient listening to my ideas. They brought in an architect who was reasonably priced and made suggestions to overall designs which I am so glad they did ! The project from Start to finish was on schedule which O was pleasantly surprised - these guys kept their words and their workers were always on time respectful of my property and time. I like that they always checked with me when they took major steps to double check that everyone was on the same page - they communicated every step of the way and were very careful to to do the job right. I really love the beautiful cabinets and marble countertops which were my dreams. I am so glad I hired these guys - they really did a great job overall - will definitely recommend them to my friends and neighbors !"

"We recently had the unfortunate experience of working with Character Companies Inc., and as government civil servants and veterans, we were deeply disappointed. The price of renovating two bathrooms and installing new LVP flooring at $70K (original quote: $84K) seemed excessive, but we hoped that the quality of service would justify the cost. Sadly, that was not the case, and it has cost us the chance to rent out our home while we are deployed to Iraq. From start to finish, the experience was a nightmare. The project management was abysmal, with multiple delays that extended the timeline one month beyond the agreed schedule. It took over two months to do just two bathrooms and replace flooring when the original timeline was four weeks. This company demonstrated a shocking lack of professionalism and accountability throughout the process. The design work was utterly incompetent, failing to conform to the existing plumbing structure in our bathrooms. The contractor disregarded our repeated attempts to bring attention to design flaws and forced the installation of bathroom vanities by performing a â carpentry fixâ that left us with two top drawers sealed shut, one bottom drawer with a cutout, and one fully functional drawer. One month after installation, one vanity separated from the wall and had to be reattached. Our allegations of Character charging us for high-end fixtures and installing cheaper ones were ignored. The final straw was the damage done to our marble floors. Instead of offering a repair or replacement, the contractor covered it with LVP and then charged us at the end of the project for the extra costs of the LVP that they incurred to cover up the damage! This was deceitful and completely unacceptable. The CEOâ s disregard for customer satisfaction and maintaining basic work standards is unforgivable. The only thing he did well was apologize profusely, not caring about fixing any problems. During a phone call, he admitted that our project was a â dumpster fireâ yet didnâ t offer any concessions. We strongly advise anyone considering Character Companies Inc. to stay far away. Their poor project management, substandard design, shoddy craftsmanship, and unprofessional conduct have left us with a costly mess that will take more time and money to fix. Protect yourself and go with an experienced, reputable company."

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.

"We just had the original kitchen in our 1968 house gutted and renewed by Vienna Prime Custom Kitchen & Bath (Prime Custom). BLUF: We highly recommend you consider them in your due diligence efforts to find a reliable & quality K&B contractor. Good internet reviews were a significant factor in selecting potential bidders for the refurbishment of our kitchen and two full bathrooms; that’s why we are submitting this robust positive feedback. In fact we are putting our money where our mouth is by awarding the refurbishment of our two main bathrooms to Prime Custom. These two combined projects are more costly than the kitchen was. Our procurement strategy was to hold back the bathrooms until they proved themselves with the kitchen. They came through in spades. Our kitchen journey from planning, contracting, detailed design, execution and final delivery was by no means a cakewalk but Prime Custom was an outstanding partner and delivered a quality product. We trust them! Believe me, we were a bigger “PitA” than any customer under the sun but Prime Custom Prime was collectively patient, understanding, informative and most importantly tolerant of their sometimes-antsy interior design challenged clueless customer. Their team, including an involved owner, consisted of Filiz the designer (PC Vienna), Nick the PM (PC Arlington), and several company employed skilled tradesmen in all disciplines, including the après project cleaning crew that were “the Best”. Even with a professional and organized contractor team doing quality work, the vagaries of ripping out and replacing a kitchen is a taxing psychological rollercoaster. Despite a detailed Statement of Work (SoW), there were lots of moving parts with so many big and small decisions throughout the project. Prime Custom did a masterful job “herding cats”. The project was 95% complete in three weeks and we were able to reclaim our new beautifulyl retooled kitchen by the middle of the fourth week. We did our homework. We developed three pages of bulletized line items, one for each room in our SoW. After interviewing a dozen K&B contractors including onsite visits and receiving half a dozen bids on our very comprehensive SoW, we culled the list down to three potential providers. Prime Custom matched the low bid for the kitchen with one contractor and the two bathrooms of another. We decided to go with Prime Custom with the hope of their doing all three rooms after they proved their worth on the kitchen. Our strategy has worked so far. We will update our review after Prime Custom completes the two bathrooms. It pays to be anal in working on home improvement project contracting, no matter how painful."

FAQs for addition to existing structure building service projects in Alexandria, VA

Yes, hidden rooms are legal, as long as they meet all local building regulations. If you sell your house, most states require homeowners to disclose full houseplans, which would include any hidden rooms.

If your secret room is a safe room, it should contain a means of communication aside from a cell phone, such as a shortwave radio. You should also have plenty of drinking water, a portable generator, emergency food supplies, blankets, pillows, flashlights, batteries and a first aid kit.

Any time you update your home’s square footage, you increase its value, but a secret room is a niche feature that doesn't rank high on every buyer’s list of must-haves. Investing your money in remodeling more common living areas like bedrooms, bathrooms, or kitchens will have a higher ROI than adding a secret room. Many secret rooms can act as entertainment spaces (think a game room or wine cellar) or quiet spaces (a library or study), so when building your secret room you may want to consider its versatility for when you’re ready to sell.
