"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."

They managed it all, from design, permit applications and inspections, to devoting meticulous attention to complete the project successfully on time and with the highest industry standards and materials. Their price is very fair and their work ethics is highly commendable and reliable. My family and I can't be happier with the end results. We'll contact them for sure again for any new home improvements."

"This company gets a 0 rating from me. My experience with Alltecs was terrible please do you research on this company before hiring them I even encourage you to go and physically see work that they have done instead of relying on their photos. I would never recommend their company for anything. I hired Alltecs for a 203K rehab July 2021 by March 2023 they quit and nothing was completed in my house. Alltecs had already been paid a substantial amount of money, for a totally f....ed up job and to add Insult to injury Dawnta Million filed a Mechanics Lien on my property in which he never enforced. The nerve of somebody who don't pay his subcontractors (found that out later) so please please please don't get defrauded by Alltecs like I did."

"Archibuild performed an over garage addition and kitchen remodel for us in 2023. From the design, bidding, execution of the work, and closing the project we had an amazing experience. Tito was the only contractor we talked with that provided a design option to achieve our goal for our kitchen without having to do an additional bump out. He quoted the work and length of time. We not only stayed within the initial budget but the work was also finished earlier than expected. Tito, Dan, and Tsiky were responsive and so helpful in making decisions on the project. We lived in the house during the renovation and they designed the timeline so that we lived without a kitchen for as little time as possible. The site was also very clean both inside and out. We didn't have to live in a dusty construction zone and our HOA gave us compliments on the project site cleanliness outside. We highly recommend Archibuild and plan on hiring them again for future projects."

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

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.
