Overview of Sliding Glass Patio Doors

Sliding patio doors remain the most popular way to access a deck or patio because they allow natural light to flood the area and provide a great view of the landscape outdoors. Replacing a sliding glass door assembly with a new unit provides upgraded appearance and performance you’ll enjoy.

An impressive range of material and cladding options plus accessories like grilles, adjustable blinds between glass panes and a spectrum of colors give you plenty of stylish choices for updating your home. In fact, most major manufacturers like Andersen, Pella, Marvin and Jeld Wen make matching patio/sliding glass doors and windows lines. For example, the Andersen 400 Series and the Pella Impervia series both include sliding glass doors.

Removing the old unit and installing a sliding glass patio door is a project a DIY homeowner with the necessary experience and tools can accomplish in a day or less.

This Costimate discusses sliding glass door replacement of a standard unit up to 70″ wide that has one fixed section and one sliding door. We’ll explain the variations in product costs, which are based on the type of door you choose, the materials, added features and options, as well as the cost differences associated with installation. At the end of this page, you’ll get to review what other homeowners paid to have a sliding glass door installed at their home, as well as what other leading websites provide for door installation estimates.

Sliding Glass Door Cost Factors

While we’re limiting this post to standard-size sliding glass doors, you still have many options that affect cost.

  • New or Replacement Sliding Doors – If you are replacing an existing set of sliding glass doors, all of the framing work on the structure is already done so it will cost much less. If new sliding doors are being installed, your home needs to have the hole cut, framing of studs and a new header, as well as the interior and exterior walls repaired and repainted after it is done.
  • Material – Your options with specific pricing below are vinyl, composite, fiberglass and wood sliding glass doors, with and without exterior cladding.
  • Quality – Glass packages, hardware, how the joints are constructed and insulation quality are all available in basic, better and best grades for all materials.
  • Options – Sliding glass doors with grilles are 5% to 15% more expensive than comparable units without them. Those with adjustable blinds between glass panes cost up to 35% more in wood and up to 100% more in vinyl, partly because the option is available on premium models with the best overall quality.
  • Color/finish – Vinyl colors other than white increase the cost by up to 40% in the same patio door series. Finished wood and exterior vinyl or aluminum cladding on wood patio doors can increase cost by up to 50% over bare wood.
  • Energy Star Glass – Many high-end sliding patio doors include glass packages certified by Energy Star, just one of the reasons for the higher cost.
  • Other Windows and Doors Installed – If you buy a package of products, the cost per unit goes down slightly. If you’re considering installing new double hung windows, casement windows or something like a kitchen garden window, you’ll get a discount by having it all done by a single contractor.
  • Who Installs the Door – DIY installation is cheapest, if the job is done properly. Handyman services charge affordable rates; The cost estimates from window and door contractors are the highest.

DIY or Hire a Pro?

I’ve replaced and installed many doors in the past. Replacing a sliding glass door is a fairly straightforward project for most skilled homeowners with the right tools. When vinyl or other types of siding are required to be repaired, it can be a bit trickier, but on most same size replacements, DIY installation is a good project.

  • Requires a truck or friend with a truck to get new door, as well as dispose of old.
  • Heavy lifting, so you’ll need a friend to help out.
  • Basic hand tools and a good level are really all you need to replace a sliding glass door.
