As with timber, the quality of pvc frames available can vary - and generally, you get what you pay for. The better ones will usually be reinforced with metal, internally, for greater strength but the cheaper options can be a nightmare to live with - sticking, twisting, splitting, discolouring, warping - often within a very short time. Most usually supplied as white, some manufacturers offer limited colour options or wood effect finishes.
Screen doors are the other option, as previously stated that can also add a rustic look to a patio. Screen doors work best for resort style homes, log cabins, and in places where the weather is generally hotter longer. A screen door is much cheaper than their metal and glass counterparts and is usually made of wood and screening. Metal screen doors will cost a little more but last longer against the elements. In choosing the correct set of patio doors for under $1000, people have a wide variety to choose from if they are willing to install them without professional help. Even so it would be hard to break the $1000 barrier unless there is a multitude of doors that need replacing. Choose the style that best fits the theme of the home and enjoy a bug free patio area for years to come.
Remove the two screws holding the bottom section of the frame. There is one screw either side of the bottom section. Once these have been removed the bottom section can be prized away from the rest of the frame. Be careful not to lever against the glass or you could shatter it. When the bottom section is clear from the rest of the frame you will be able to remove the wheels. Some wheels have a screw holding them in and some are pressed into a holding bracket. If the retaining screws have rusted you can carefully drill them out, taking care not to make the hole in the bottom section any bigger. Contact your local Hardware Store, Glazing Shop or search on Google for replacement wheels.
