How do I preview wall treatments before painting or installation?

To preview wall treatments before committing, use virtual room design tools like ReimagineHome. Upload your room photo and try different paint colors, wallpaper patterns, wall tiles, wood paneling, or brick veneer side by side. This helps visualize how treatments interact with lighting, furniture, and scale, reducing risk of costly mistakes. Also, test paint samples on wall sections and observe at various times of day to see true color and finish.
