DC Rowhouse Renovation - Exterior finishes / by Gregory Upwall

For the exterior of this house we wanted to select finishes that would differentiate the original building from the new addition while still creating a complimentary juxtaposition. Thankfully, we were able to complete the installation of the exterior wall cladding and painting of brick walls in time before the winter season set in. The exterior of the house had been painted with many layers over the years and was badly flaking. We used a product by Prosoco to strip off the old paint. Then patched up any areas where the mortar had come loose. For the paint we chose Sherwin Williams masonry primer and their premium exterior acrylic paint in a flat finish.

 For the exterior on the new 3rdstory and rear additions we chose custom metal panels that were fabricated according to our drawings in Galvalume. The panels are designed to clip together and were installed starting at the lowest course with each successive course clipping the course below - as they are installed. The design for the staggered horizontal rows was conceived to mimic coursing and stacking of masonry, but in this case expressed in an abstracted manner with a more modern material. We felt that this allowed for the original house to remain visually distinct from the new while still complimenting each other. The same metal was used to cover the fascia band around the perimeter of the roof edge. We wanted to avoid using many different cladding materials, and instead chose a mono-chromatic pallette to give the house a more cohesive and less fragmented look.

 The metal cladding was installed over a flexible weather barrier manufactured by Pro-Clima that is specially suited for installation below metal cladding The product, called Solitex UM, combines a flexible vapor open membrane with an extruded “3d mesh” that is integrated on the exterior surface and creates an air space behind the metal cladding to allow any trapped moisture to dry from behind the panels.

The front of the house was meticulously stripped using a masonry stripping agent (And lot’s of manual scraping). The cornice trim and frieze are all the original tin which was stripped and repainted by hand.
