Patio Door Installation Guide

Successful patio door installation is dependent upon several important factors. The size of the existing door, the style of that door, the material surrounding it, and, of course, the design and dimensions of the new door will each play a role in how this project is performed. Unless you are building a new home or addition, the easiest way to perform this task is to replace the existing door with one of identical dimensions. However, homeowners seeking to brighten up interior spaces or create a larger, more convenient portal to the outside for large items may decide that increasing the size of the opening is worth the additional expense and effort.

  1. When selecting your door, having a good contractor on hand to help with the decision is incredibly valuable.

    1.Choosing a Quality Door

    One of the first things most homeowners will need to consider when entering into this project is the make and model of the door to be installed. The current market offers more than enough options to please any homeowner, but because there is so much to choose from, finding a good-quality door at an affordable price can be difficult.


    When selecting your door, having a good contractor on hand to help with the decision is incredibly valuable. He or she will not only be able to tell you which models of doors tend to give you the most for your money, but also which features (double-paned glass, tinting, etc.) will be the most advantageous to have in your area. A door that is perfectly fine when installed in a location that sees mild winters may be far less appropriate for colder climates. An experienced contractor will have seen many of these units in action, and he or she will be able to point you in the right direction when it comes to function without sacrificing your aesthetic tastes.

  2. 2.Patio Door Options

    When building a home or addition from the ground up, there's little limit when it comes to the design and features a patio door can have. However, since most homeowners considering this task will be replacing an existing unit, the space it will have to fit into may not accommodate some designs. Most existing openings will have no problem being fitted with a run-of-the-mill sliding door, swinging French doors, or a door that includes a pet door, but pocket doors, stacking doors, transoms, and door automation may not be an option for every existing space.

  3. 3.Security Features

    According to FBI statistics, there were more than 1.4 million residential burglaries in the U.S. in 2010, and since many burglars gain access to houses through unlocked or ineffectively locked doors, the type of security features your patio door includes should be a consideration. Though few burglars will break the glass of patio doors to gain access, heavy-duty glass that resists impact is certainly available. In general, a lock that works supplemented with a security bar and a design that does not allow the door itself to be unhinged or taken off its track from the outside will prevent a would-be burglar from finding the easy access he or she is looking for.


    Since many patio doors provide a direct route to pools, grills, and other things kids should stay clear of, it is also important for homeowners with children to make sure that their new door is secure from the interior as well.

  5. 4.Identifying the Right Contractor for the Job

    Some handy homeowners might attempt to install patio doors without the aid of a professional, but since this operation may require tools and skill-sets that many of us simply don't possess, quite a few more will leave this job to the professionals. A good door contractor will be easy to communicate with, offer you the advice you need to pick the right door for your needs, and will be happy to explain the process (and the expenses associated with it) to you. No matter what the job, it is always a good idea to contact at least three contractors in your area and get quotes from them all. This will give you a much better idea of what the going rate is for your specific project, and also give you a better chance of finding a contractor who you really click with.
