Home Depot stores cater to do-it-yourselfers, as well as home improvement, construction and building maintenance professionals. Stores have a design center staffed by professional designers who offer free in-store consultation for home improvement projects ranging from lighting to computer-assisted design for kitchens and bathrooms. Most Home Depot stores offer installation services. Services can range from single-item installations such as ceiling fans and carpet to more extensive projects such as kitchen cabinet installation. Their warehouse-style stores sell everything your house may need, and that's including the kitchen sink. Looking to decorate it? Install it? Grow it? Build it? Fix it? Boasting more than 40,000 different products, it is likely that the parts are all here for you. Certain locations are even open 24 hours.
