Doors can create just as much of an impression as an expensive piece of furniture. They are touched and seen close up every day, so don't just go for the cheapest replacements - try to match the style to the rest of your home's features as much as possible. Updating a door also gives you the chance to let light into a dingy hallway or room by choosing a glazed finish. Or, you can give a house a contemporary upgrade simply by replacing cheap blanks with doors with a little character.

Remember, though, that swapping doors may not be entirely straightforward. You may need to add an extra central hinge to support a heavier door and the timber strips around the inside of the door frame, the stops, may need to be prised off and moved to allow for a different width door. What's more, your door frames, particularly in an older house, may not match standard sizes or be entirely straight, so your new ones may need trimming to fit.
