In Our Customer’s Words

Moss Building and Design is fantastic! We used them last year for a major remodel to our new house, and we were very pleased. This year we wanted to make some major changes to our daylight basement. We again went through the process of soliciting bids from four solid remodeling companies to make sure that we had a good sense of cost. Based on our prior experience with Moss, their great employees and management, practical design, and price, we picked Moss again. Like last time, they were not the lowest bidder nor the highest in terms of price. (Note: This is the FIRST remodeling contractor that we have ever chosen to do business with a second time.) One of the owners, Justin, came out to the house and confirmed that we could have the same project manager again. We requested Bob Keene, as well as the same customer care manager, Kristen Corbett. Why? Because they had done such a great job last time and because they have always been pleasant, honest, flexible, and direct with us. So, Bob and Kristen helped us again with numerous design and materials decisions. They and the entire Moss team helped us stay on track. Moss, as a company, and as individual employees, knows how to keep a project moving forward and completed in the agreed upon timeframe. They were flexible when we decided to add crown molding to the scope of work. We were flexible in that it would take a bit more time. End result: Our daylight basement is stunning! The bathroom now has a great layout and is aging-in-place friendly and gorgeous! Our laundry room now works for us too. Bottom line: Moss does outstanding work by skilled, permanent employees; provides superior service (Bob and Kristen always took my calls or called me back on the same day), and offers a fair price. We would choose them again without hesitation. Check their references, and you will see lots of repeat customers.

Wonderful. The design stage was completely transparent. We received careful plans before we had to pay a dime, and the price was very competitive. Work began and finished on time every day, and the craftsmanship was consistently excellent. The project manager, Matt Alspaugh, went above and beyond, personally attending to even minor details. The team religiously kept to its schedule, and we moved in right on time. Overall, I can’t imagine a better experience. P.S. Moss has remained extremely response even after receiving its final payment.

We needed additional living space for our growing family but were unsure of what to expect with a project of this scale and magnitude. Well, Moss surpassed our expectations in every way. Starting with the proposal phase, through communication and meaningful discourse that stem from truly listening to the client, the owner-rep ascertained our needs and intended use for additional space and gave us all the information we needed UP-FRONT to make our start decision. My husband and I were very impressed not only by his expertise and knowledge, but also by his honesty, fair-dealing and willingness to work with us and share cost and other information, where other design-build firms were equivocal or “hiding the ball” on such details. After contract signing, a similarly productive design phase followed, where the architectural details brought real vision to the project. This stage followed our pace, and we were neither rushed to make decisions nor delayed from moving forward. Once the design plans were finalized, Matt (the project manager) took over, and then miracles started happening. With amazing planning, scheduling and organizational skills, Matt marshaled multiple crews and trades to execute the master plan with no delays or excuses, until the job was DONE and DONE WELL. That’s priceless. Moreover, Matt conducted himself and his team with upmost expertise, professionalism, courtesy and responsiveness, while showing sensitivity to our family’s needs (we and our 4 young kids lived in the house during construction). Tirelessly, he navigated us through the myriad of decisions and issues inherent in a project of this size and duration. Any problems that surfaced were handled immediately and effectively. Our customer care rep, Jodi, also ensured that we were on-schedule with materials selections and planned and attended our meetings with vendors, offering excellent advice that comes from many years of experience and a track record of many successful projects. Today, as we enjoy the comfort, luxury and practicality of our new master suite, we could not be happier that we selected Moss for this life-changing project. They have not only made our dreams a reality, they showed us how to improve on those dreams, and they did it all with their genuine customer-focused, family-friendly approach. Without question, Moss will be handling any of our future building/remodeling needs, and we have also enthusiastically recommended them to friends and neighbors.

We started the project in Nov 2013 and completed in late May 2014. The design process and county approval took until early Feb 2014. The project started in late February and was delayed a bit due to weather. Our project manager, Brandon Sarina, was terrific and helped ensure we knew what was happening with every stage of the project. He also helped with any questions or minor adjustments we needed to make along the way. He was always quick to respond and extremely helpful and proactive. Our construction team was terrific. Andrew (foreman), Joe and Alex were on this job the entire time and are extremely skilled. They worked well together, and they were also extremely attentive and went out of their way to answer questions. They kept the work site very clean during the project, which made living in a construction zone easier for us. Overall, we are thrilled with the finished product.

Moss has a solid reputation for quality construction and an experience team of sales consultant, in-house architect, project managers, interior designer, and carpenters which is why we selected Moss among the other builders.  Lisa Ladson, Moss' sale consultant, coordinated with their in-house architect (New leaf collaborative, architecture and design) to provide us with an open concept and second floor layout that we love.  Lisa was exceptional and very responsive during the preliminary design stage.  Moss also provided 8-hours of interior design which made all the difference in helping us create the look and feel of the interior and exterior.  We couldn't wait for the construction to start considering the positive design experience. The construction start was less than perfect with the initially assigned project manager not meeting our expectations in communicating the status and keeping to the schedule.  We voiced our concerns and Moss' management quickly responded and assigned David Keys, Moss' Senior Project Manager, to get the project back on track and to improve communication and owner expectations.  David took over 2-months after construction had started and we emphasized the expectation of the 5-month construction.  Now the Moss online schedule was not valid anymore but instead Dave and I met weekly for him to provide me with the construction status and a 2-week look ahead of activities.  Dave's style of construction management and owner communication enabled the construction to be completed in 5-months -it pays to have an experienced Project Manager from the start.  Dave was very responsive to any post-construction issues and continues to be my go-to person for any issues.  Overall, Moss did a terrific job considering the initial construction setback, but they came through per their reputation.

They did all the work. We signed a contract in March last year, they started construction in May with the idea that we will be finished by the 4th of July. They finished last Thursday. When they first came, they did an excellent design. They had excellent customer service. They assigned a great project manager. They removed that project manager and assigned another one. It was a train wreck. The second manager they assigned had all kinds of personal problems and was not providing supervision to job and we were going weeks without any work being done and he quit in the midst of it. Moss has a wide range of contractors and they had a new sub contractor. They had painters painting and it rained and water was cascading on the additional. You get to the point where you have to be rude to get them to do work. Their customer care started to deteriorate and they were getting frustrated. They had to redo the work. It became impossible to get the contractor or supervisor. I would not recommend them.

We interviewed 4 different Contractors to rebuild our 2 car garage after losing it to hurricane Sandy. Moss Building & Design met with us and prepared a comprehensive plan. The only reason we chose another Contractor was our desire to reuse the original brick in the rebuild. So when we began our plans to remodel our kitchen and powder room we hired Moss immediately. Our designer worked quickly to present us with plans that included all the ideas we had discussed. The scope of the project was considered and our budget was adhered to. When we added several things that wern't initially considered Moss willingly worked with us to incorporate our desires. We would hire Moss again and highly recommend them for both large and smaller projects.

Our goal is for you to be 100% satisfied. We create a home that you’re proud of, but it doesn’t end there. Once you are a Moss customer, you are part of the MOSS family for life.

Kitchen Bump-Out

If your kitchen and/or family room is too small or you want an eat-in kitchen, a great room, or a mudroom, a bump-out may be the way to go. Bump-outs are often smaller sized additions that will add a new room or add space to an existing room or rooms.

MOSS will provide you with a MOSS 360 Architect in addition to a Project Designer to make sure that the footprint of your home bump-out as well as the interior layout meets your needs.  Your MOSS team will collaborate with you to ensure that the additional space added to your home accomplishes your goals and maximizes your value.  A kitchen bump-out sets the stage to make additions and changes to your existing home that improve the quality of your life in your home every single day.

Master Suite Addition or In-Law Suite Addition

Master suite additions are very popular in Northern Virginia.  Most Northern Virginia homes are older so they are well built but lacking modern amenities.  A modern master suite has a comfortably sized bed area, walk-in closets, and a bathroom that is beautiful and functional.  A Master Suite addition has a very high return on investment in terms of your every day enjoyment and resale.

In-law suites are also very popular in Northern Virginia due in part to the high cost of housing.  If designed right, they also serve a dual purpose of having the long-term benefit of a main-level master suite.  MOSS has built many in-law suites in Northern Virginia.  Let us put our experience to work for your Northern Virginia in-law suite.

Pop-Top or Second Story Addition

If you have a small lot and a one or two-story home, a pop-up or second story addition might be the way to go. It allows you to take advantage of the free space above your house, avoids taking up valuable yard space, and often avoids zoning restrictions and significant excavation and foundation work. This is a particularly good option for a one story ranch or rambler home that feels cramped. But it is also a great option for a split-level or split-foyer home in need of a nice master suite or additional bedrooms and bathrooms.

Second story additions are a very economical way to add significant space to your home.  But the design has to be right!  Our MOSS industry-changing design experience is the perfect way to explore the options and design your beautifully expanded home.

Deck or Porch Addition

Decks and porches allow you to transition from the interior of your home to the outdoors. Today, some such structures are becoming elaborate outside rooms but you can also build a simple deck on a smaller budget or add a front porch to your home to increase its curb appeal. The return on a deck or porch addition is around 90 percent.

Single-Room Addition

Sometimes your home just needs one additional room!  Many homeowners are adding on single rooms for home offices, bedrooms, home theaters, sun rooms and bathrooms. Family room additions are also very popular, allowing for more functional spaces off the kitchen.

Two-Story Addition or Three-Story Addition

If you need more square footage on multiple levels of your home, a two-story or three-story addition is the way to go. For example, you can add a kitchen and/or family room bump-out on the first floor while adding a master suite upstairs.  And if the budget allows… some finished basement space is always a bonus!  Two-story or three-story additions are very popular in Northern Virginia, particularly for more traditional existing two-story colonial homes. The multiple levels drive cost efficiency since they often share the same roof and foundation.

Home additions are the perfect solution for growing families, families who permanently host the in-laws, or for people who simply need more space.

While some remodeling projects can free up space, home additions are the only projects that allow square footage to be added. When we meet with you, we will talk you through the different possibilities for your home. You’ll even get to experience your new space before construction even begins with MOSS 360.
