Picking Cosmo Home Addition Contractor for our big home makeover in Washington DC was a smart move. We tackled a kitchen, living room, two bedrooms, and a master bath project, all expertly managed by their team. They gave us a straightforward cost breakdown and seamlessly handled design, permits, and construction. Cosmo was fantastic. Our kitchen is now a dream, equipped with the latest, and it’s incredibly functional. The living room has turned into the ultimate gathering spot, open and inviting. The bedrooms are a hit with the family, and our master bath? It’s like stepping into a spa every day. They were great about keeping us in the loop, sticking to our budget, and finishing everything on time. Plus, they used top-notch, eco-friendly materials. The transformation of our DC home is just breathtaking, especially the kitchen and living room. Cosmo made sure our investment paid off. For anyone in Washington DC looking for a reliable home addition contractor, I highly recommend Cosmo Home Addition Contractor DC. They're straightforward, dependable, and truly make your budget work wonders. Thanks Keep growing💰🏠👷🏼🎉

We have just had our basement remodeled and what a surprise for us when we go in to check and it is a hundred times better than we could have ever had imagined. Initially, we had so many ideas for the basement and it was hard for us to choose, so we let the construction company decide on some indecisive aspects that my wife and I had, and we couldn’t have made a better choice. Will certainly use their services when we decide to refurbish another part of the house.

Details: Complete room renovation • No existing plans, but have a good idea of what I want • Residential

Thank you, Amy. We were happy to get that basement done for you as quickly as possible. Hope your enjoying it as much as we enjoyed building and working for you. We’ll definitely work with you on future projects. Best, Cosmo Builders

Cosmo Builders recently completed a basement renovation project at my home. Their team of talented staff successfully handled demolition, hauling away debris, ordering and delivering materials (laminate flooring, six-panel doors, LED lighting, frameless hinged shower door, ceramic tile, toilet, interior doors, bathroom vanity, etc.), painting, plumbing, as well as electrical services. From estimates and architectural drawings, to permits and scheduling, I was impressed by their professionalism, integrity, and flexibility throughout the process. As new home improvement projects are identified, Cosmo Builders will be my #1 choice!
