We had a good experience working with Hammer through a large, complex remodel of our home. Hammer worked collaboratively across their teams from beginning to end: from concept and preliminary pricing, design, documentation, permitting, and all the way through construction.

Because of their integrated approach they were able to quickly address issues as they arose and kept us fully informed all along the way. Additionally, Hammer led our project with a commitment to quality and doing the right thing. I recommend Hammer for all of these reasons.

Our experience with Hammer was exceptional. We had a fantastic Project Manager who was really good at communicating which is always important. They worked hard, were thoughtful during construction, and produced a stunning kitchen. We are very happy with our experience with Hammer.

I had been putting off renovating my DC row home for years and it needed a lot of work. I was overwhelmed and didn't know where to start but the Hammer team walked me through the whole process from start to finish.  They explained all my options and came up with multiple plans for me at various price points.  I really appreciated the time they took to thoroughly explain everything and I never felt rushed or pressured.  My project manager, Victor, and my designers, Johanna and Rebecca, were fantastic.  They kept me well informed and the project was completed ahead of schedule.  I couldn't be happier with the results and I will definitely use Hammer again for future projects.

A friend referred me to Hammer (Greg).  This friend did a whole house remodel with Hammer and was pleased beyond expectations.  They found Hammer after they parted ways with the previous Design/build firm who was doing a poor job.  Their house turned out amazingly and it has been in at least one interior design magazine.  I was interested in getting Hammer to weigh in on some interior changes to a house we were considering buying.  Greg was very upfront in that Hammer is not licensed in Virginia.  After that he not only recommended other firms but he spent 40 minutes on the call with me to educate me, give me pointers on what to ask/ascertain.  Most importantly he gave me some high level pricing guidance with minimal input from me.  The time Greg spent with me was extremely worthwhile.  I'd use Hammer for sure given the opportunity.  Thanks Greg, team!

Highly recommend. Hammer designed and built a beautiful new kitchen in my 110+ y.o. apartment. The construction crew was professional, courteous, always on time and quiet--my neighbors had ZERO complaints. My project manager, Victor Alcantara, was highly responsive and very helpful in providing options and explanations to resolve surprises that arose during the construction process (in a century -old building, there are lots of complications.) The crew left my apartment clean and in great condition at the end of the project.

Victor Alcantara and his team did a fantastic job leading a major home renovation project in Bethesda this year. Victor is extremely careful and diligent in his work and management of projects. He truly cares about the quality of his team's work and is always available to answer questions or address concerns. We found it very easy to work with Victor and were able to truly trust him. We would highly recommend Victor to anyone considering a home renovation project.

We worked with Hammer to renovate our kitchen, living room, and master bathroom. We found their work to be exceptionally detail oriented. We particularly enjoyed working with Johanna as the designer and Victor as the project manager. Johanna spent hours identifying solutions for our house, including finding an in-ceiling mini-split and an exceptional door for an atypical space. She would push back gently on any ideas that she thought wouldn't work or would cost too much beyond what we had targeted. Victor came on as our project manager midway through the project, and we particularly enjoyed working with him. He was extraordinarily detail-oriented and very good at communicating. Despite being new to Hammer and our project, it was immediately clear through his knowledge of our project's details during our first meeting that he was someone dedicated to delivering a great project and fantastic experience. He spent hours talking with us and provided detailed follow-up notes. Although the project did take a little longer than expected, there were no major hiccups, and if Hammer came to us with any small problems or changes, they also provided multiple options for solutions. If there was ever a slight mistake, they corrected it - they truly strived to deliver what was agreed to. Victor was very conciliatory and regretful when explaining why a relatively minor aspect of the project could not be delivered as desired. Hammer managed all of the details of inspections, paperwork, and contractors. They treated our house with care. For finishing work (painting, drywall repair, etc), we admired the skills of Manuel and Carlos, and found them to be exceptionally kind and highly skilled. They were personable and even shared about how they did some things. During the project development stage, Hammer worked with us to set some cost expectations where the cost of the project might increase. For example, the expense of a new electrical sub-panel was not included in the project but they told us how much it would be in case we did need to add it (fortunately we still have a single opening in our current utility box). They know it is not in anyone’s interest to have a significant cost arise during the project - especially when there is a statistically significant chance of it occurring. Elsewhere in the planning phase, they investigated behind our walls multiple times before major work commenced to refine what they needed and provide more accurate cost estimates. Overall, we really enjoyed working with Johanna and Victor and would be happy to collaborate on another project with them in the future.

This is a whole house rebuilt; we worked with an architect who produced no desirable results but extended hourly bills. Hammer changed that. Hammer's design teams understood what we desired for and found solutions within our budget; Hammer's production team paid attention to details for a high quality work.

We found Hammer on internet searches without prior recommendations. This is a whole house rebuilt job. Hammer's design team worked with our ideas then created a plan better than what we imagined. Hammer's production team worked solid, paid attentions to details and are responsive to all concerns we encountered. We highly recommend Hammer.

Highly recommended. I hired Hammer to renovate my cooperative apartment, including entire redo of the kitchen and bathroom (including moving some walls to create new space), revision of closet doors and spaces, refinish of all hardwood floors, install ceiling lighting/fans, and fix old electrical outlets and breaker box. It was a big job in a coop apartment requiring some serious interaction by Hammer with the Coop Board and neighbors (and also during COVID, requiring certain shut-down periods and special protections required by the building). Hammer folks were on top of it all the way; incredibly helpful in working with the Coop & neighbors; kept me updated; were extraordinarily easy to communicate with and get responses from very quickly; and generally great to work with. And I say this as one who is most often disappointed by home service providers. I'm thankful that I could be so pleasantly surprised by my experience with Hammer. And the final result was really of fine quality. Walls taken down & new ones installed; hardwood flooring added to match to existing & all refinished; all the new kitchen and bathroom elements turned out excellent. No shoddy work here. Moreover, there were several original architectural details, such as original 1920's glass-paneled doors, that Hammer refinished and maintained in great shape. And all little punch-list items were fixed perfectly by the end.

Our small "water issue" job turned into a complete back of house two story renovation. Hammer did a fantastic job, and helped us get through the project as new homeowners who had no idea what we were getting in to. We had a lot of structural and framing issues hiding behind our 1911 home's walls. Between managing our plumbing updates around our existing ductwork, structural updates, complete exterior update, they kept us informed of all our options and provided ways so stay on budget. Greg was always there to answer any questions, no matter the time of day. We are very appreciative of him and his team. The  team went above and beyond several times to make the final product a cohesive one (ie finishing the new floor path to match the old on their dime/time). Huge thank you to him and his team.

Like many other DC homeowners, we purchased our row home “as-is” in July of this year. We knew that we would need some work done to fix what we believed to be “minor” water damage issues. Well, long story short, it turns out the entire back of our house was falling apart from a combination of water and termite damage and we needed all new plumbing. Hammer has been a silver lining in this otherwise trying time. Greg has worked with us over the past 2+ months to stick as closely to our budget as possible even in the wake of new and expensive discoveries that have popped up during the remodel. Greg’s team is professional and respectful. They took our concerns seriously, including the one about keeping our two cats safe from the construction work. Although it is unfortunate that we needed the extent of work done that we did, we are very glad we chose Hammer to help us. Greg had to coordinate numerous different trades because of our extensive list of repairs, and we felt confident in both his ability to do so and the ability in the different contractors he worked with along the way. We look forward to working with Greg and Hammer in the future, hopefully on cosmetic rather than structural work!

I cannot recommend Hammer Contractors highly enough. The company remodeled our master bedroom in October and we are thrilled with the results! From the start, our designer listened to our needs, provided insightful feedback and ultimately created a beautiful rendering that matched the final product. Following the design phase, our project manager was in constant communication with us regarding timing and costs to ensure our project stayed on track and within our budget. When an unexpected issue arose, the project manager walked us through his findings and provided a range of options, instead of trying to force us into a costly fix. The crew members assigned to our bathroom were very professional, in addition to being skillful at what they do. We plan to remodel our kitchen this Summer and definitely plan to use Hammer!

HAMMER TIME !!  Our project was huge and we had a million questions and concerns.   From the pre-meeting on Day 1 to the final walk-through, our whole-house remodel was more than the welcome transformation we had anticipated.   Hammer contractors held our hands through the entire process, and easily incorporated our ideas and thoughts into their architectural designs - as well as allowing me to get my hands dirty to help reduce cost.   We were impressed with the project management and communication throughout the entire process.   Hammer had more than enough expertise to do the job right... the first time.. and fixed any and every potential problem that they uncovered during demolition (the quality and longevity of any project is mostly due to what you can't see - behind the finished walls).   When our project went a bit outside their comfort zone (like shellac-ing the entire first floor due to nicotine staining) Hammer contractors engaged the experts at Sherwin-William to make sure they had the right materials and procedures to get it done right.  Thank you Hammer.

If you are looking for a contractor for your home improvement needs, I can highly recommend Hammer Contractors. We couldn’t be more pleased with our new basement or our experience with Hammer Contractors. What we appreciated most about the team was how responsive and caring each and every person was that we encountered during the process. Everyone on the team has a genuinely positive and friendly attitude and they were excited to help us plan and bring about the basement we wanted. This is a team of knowledgeable professionals who hold themselves to a high quality both in product and in service. They utilize a website personalized to your project and it was a great way to stay connected, track progress and approve selections. A member of the Hammer team was always available and promptly responsive to all our inquiries. Every evening the workers tidied up before leaving and were always respectful of our home. The project went smoothly and was completed within the allotted timeframe. We are very happy that we chose Hammer for our home improvement needs and we would do so again. We were so happy with the service and quality provided and we love our new basement. During every step of the process from introduction to design to completion, everyone on these teams made this a great experience for us. -The Kaisers

Hammer Contractors have a wonderful team with all professionals. Talented designer Andres has presented great design ideas and provided all kind of guidance thru out the design and implementation process. Jorge and his production team have delivered excellent results and courteously followed up with all details. Last but not the least, Greg has shown their committment for customer satisfaction and vision for their business success for the long run. It has been a great pleasure working with them and I will definitely use them in future.

We recently were looking to build an addition to our single family home to build an in-law suite. After multiple meetings, we decided on Hammer Contractors for this addition. Hammer Contractors were very professional and patient with our multiple questions and needs. Everyone we worked with were friendly, knowledgeable and an expert in the field. We worked with their design specialist to create the best design with the space available. The account/sales manager was very patient and provided all details and help needed on our project. The project manager communicated with us the entire time and ensured the project stayed on track as best as possible. The craftsmanship was top notch and everything was done as described in our plan. We finished the project and our in-laws have moved in and started using the space with great happiness. For our next project, we will only need to call one company, Hammer Contractors for any and all needs with our home.

We were very pleased with the whole process from start to finish. The design team Andres and Greg and the construction team Jorge and Johan were excellent. I needed a lot of hand holding to transition our kitchen/dining/living room into an open concept living space. They reinforced the roof beams and repaired years old cracks in the ceiling while taking down the walls to our kitchen. We love the new look and all the details that were added. The communication is very good and they were right on schedule even with THREE snow storms to deal with. I would recommend them highly!

Hammer just finished a total kitchen remodel for us. We had hesitated doing anything because we didn't know what we wanted, just what we wanted changed.  Andres and Greg devised a great design with our input, and Jorge and his top-notch crew built it in about a month.  They were hard working and meticulous; kept the space clean during demolition and construction; and worked quickly and efficiently. We recommend them without hesitation.

We have used Hammer Contractors on two occasions and have been thoroughly impressed on both occasions. Their attention to detail, great customer contact, personal service has far exceeded any experiences we've had with other contractors. Greg and Jorge, and their entire team, want to be proud of all the work they do--from small jobs to much larger jobs. We've used Hammer for major house repair after storm damage and for upgrades to our home. We highly recommend them!

I've used Hammer Contractors three times for various renovation projects in 18 months. They've helped me renovate my kitchen, bathrooms, roof, flooring, and closets in bedrooms. They are the most organized and professional I've ever worked with. I liked that I was able to go to their website to check on the calendar of works, to choose products, to keep track of my budget, and to communicate with them my concerns. I am very satisfied with the quality of the work they've done for me and enjoy not only the appearance of my house, but also the efficient and convenient use of space.

Hammer Contractors Inc brought their devoted and highly skilled craftsmen into our home and created our dream master bath and walk in closet. Greg assigned a designer who assisted me with selecting everything from paint color to tile and fixtures.  Jorge was an attentive site manager and his crew showed up promptly each day to keep the project right on schedule. It was a pleasure having them in our home.

Greg renovated our bathrooms few years ago. They did an amazing job then. When we need to renovate the kitchen, we didn't hesitate to call Greg. Our kitchen renovation was completed recently. Greg and Hammer Contractors did a fantastic job. He walked us through the whole process, advising us along the way. We communicated constantly and love the job status on the web! Any issues were resolved promptly and to our satisfaction. The whole Hammer crews were courteous and knowledgeable. We highly recommend Greg and Hammer Contractors for their workmanship and professionalism.
