A garden window is one of the few windows that give your home dimension. These windows are designed to extend outward into external areas, capturing light and pleasant air flow from several directions. It contains shelf space that can accommodate plants, spices, and other decorations. Because of this, they’re often installed over the sink, but they can be placed anywhere in your home.

Andrew and his team were amazing! The project took several days (demolish and rebuild a staircase and supporting wall). They were on time EVERY day and truly cared about my property. They hung plastic and ensured that the dirt/dust from the project did not permeate the rest of the house.

From the very beginning, Andrew Cosello was professional and knowledgeable. He gave us a fair and appropriate estimate for the job. He communicated well with us throughout the entire job – from informing us as to when the job would begin as well as updates about how long the job would take.

After receiving 7 quotes for the project, we hired Cosello Construction. Cosello’s quote was not the cheapest or the most expensive. We feel that we got what we paid for by hiring Cosello Construction: quality craftmanship, experience, and an industry professional. Cosello Construction worked with our architectural plans and completed the work masterfully.

Andrew and his assistants do excellent work. We had them do major renovations on our investment property, so we hired him for some minor work in our own home. We were very pleased with the work done on both properties and would recommend them to a friend or relative without hesitation.
