General Home Additions Questions
How do you match the new addition to my existing home?
We carefully source matching or complementary materials including roofing, siding, windows, and trim. Our designers study your home's architectural style to ensure rooflines, proportions, and details blend seamlessly. When exact matches aren't available, we design transitions that look intentional and enhance your home's overall appearance.
Do I need to move out during construction?
Usually not. We carefully plan construction phases to maintain livable conditions in your existing home. We create weather-tight barriers before opening any walls, manage dust and debris, and schedule noisy work during reasonable hours. Most families stay in their homes throughout addition construction.
