With the opening weatherproofed, it is now time to install the door. Get a helper for this next step.

  • While standing outside, angle the pre-hung door with the top tilted toward you. This will allow you to insert the bottom of the door first. Push the door in to fit it into the opening. The new doorframe should be flush with the outside siding.
  • Step inside the house and check for gaps around the doorframe. Insert shims as necessary to keep the door plumb and level.

Unit Costs: How Pros Price

Unlike websites which blend pricing from dissimilar jobs, Homewyse creates custom estimates from Unit Costs. The Unit Cost method is based on job specific detail and current costs. Contracting, trade, design and maintenance businesses rely on the Unit Cost method for transparency, accuracy and fair profits.

Measure The Rough Opening

Before shopping for a new patio door, you first need to determine the measurements of the existing opening. This will help you buy the right size door.

  • Using a putty knife, carefully pry out the interior trim around the doorframe to access the studs. If the trim is in good shape, set the pieces aside to reuse later.
  • Using a tape measure, determine the width of the door opening. Start measuring from the left stud to the right side one. It is best to measure horizontally at the top, middle, and bottom of the opening for accuracy. Note these measurements and use the smallest one as the width to buy a perfectly fitting door.
  • Next, measure the height. Start from the top of the opening down to the floor. Note these measurements and use the smallest one when buying your new door.

Average Cost To Install A Patio Door

Hiring a professional to install your patio door will cost between $400 and $1,400 in most situations. The total amount will include measuring and preparing the opening, trimming the door as needed, setting up the work site, and actual installation. Disposal of installation waste and other debris is typically included in the price.

Most contractors begin the project by evaluating the site and giving a quote. Conditions and size of project will determine door options and materials to be ordered. Several factors can alter installation costs. Delicate or custom materials don’t just cost more, but also require additional labor. Unfavorable site conditions may require additional installation. Pre-hung doors are more expensive, but decrease the installation price.

Are Patio Doors Easy To Replace

How to Replace a Patio Door

Replacing an existing set of patio doors is usually straightforward, providing you are not altering the size of the opening where the new system will be fitted.

If you are increasing the gap to install a broader run, some extra structural work might be needed to support the additional load. Usually, the wider the opening, the more complex the engineering becomes.

For spans of sliders/bifolds more than 3m, you may need to bring in a structural engineer who can put together a suitable design solution, which will drive up costs. In most cases, a steel lintel inserted at the head of the opening will do the job.


‘In terms of installation complications, you shouldnt come across any issues if you use a professional glazing company,’ says Ryan from Thames Valley Windows.

‘However, some general mistakes when professionals are not appointed include incorrect measurements, over tightening and incorrect screws.’

In this project by Granit Architects, steel frame doors and surrounding fixed glazing were chosen to make the most of the lofty floor to ceiling height in the kitchen-diner. The slim glazing bars complement the style of the traditional windows throughout the rest of the historic property.

Screen Door Costs Insulation And Other Factors

In addition to labor and materials, other factors can affect the total cost of your patio door installation or replacement project:


  • Screen doors: $100-$250. Helps keep insects out even as air flows into the home. Compare the cost of a screen door to less expensive retractable screen doors.
  • Added insulation: $300-$600. Helps reduce energy bills.
  • Security: $30-$300. Dual point locks or locking systems.

Other cost factors are less exact and similar to exterior door installation. They include access difficulty, reusing part of the old frame where possible, treatment and painting of wooden doors, and any structural concerns related to the door opening.

Preparing The Patio Door

In order to avoid shipping damage, special protective foils are applied to the exterior surfaces of patio doors and windows. Before installing your patio door, remove the foil from the parts of the frame that will be attached to the reveal, as removing the foil afterwards may prove to be very difficult. All other pieces of foil should only be removed after installation. .

  • Attach the handle in the correct position on the door and open the leaf. .
  • Lift the leaf out of the frame. In order to do this, the upper security pin can be removed in a downward motion using a slotted screwdriver, enabling the leaf to be lifted upwards out of the hinges. .
  • Place the leaf on soft padding material. Massive aluminium patio doors can easily damage wooden floors during installation, while the surfaces of wooden, aluminium and uPVC leafs may also cause damage or be damaged themselves. When all preparations are finished, the actual installation of your patio door can begin. The average installation time for a patio door is about two to three hours.

The procedure is the same with wood, aluminium and uPVC patio door leafs. Further tips and advice for unhinging leafs can also be found here.

Porch And Patio Retractable Screen Replacement Costs

Retractable models for the patio come in two essential varieties. The first features a soft frame that you can zip to close. The of this kind ranges from $4.50 to $6.50 per square foot, assuming that you already have a patio or porch base and cover.


For other styles that offer a hard frame that you can pull open and close, or motorized options, you may expect to pay as much as $400 per unit. Patching can function as a temporary fix for ripped or damaged mesh. But, replacement often serves as the best way to keep the material looking its best. Installation for this service sits around $50 to $75 per hour, and may take an hour or several hours, depending on the size and number of screens.

  • Pro tip: Most likely, the threshold will be glued to the floor with beads of sealant, and it may take substantial prying with a flat bar to free it.
  • Once the frame is out of the opening, cut it into chunks for disposal.
    • Begin flashing at the bottom.
    • Apply flexible flashing directly under the doorsill and two inches up the sides.

    Buy The Right Sliding Door For Your Needs

    Sliding glass doors work more or less the same but they come in different styles. An important consideration when shopping for one is the material, with the most common ones being fiberglass, vinyl, wood, and steel.

    Fiberglass and aluminum pre-hung doors are popular due to their durability and energy efficiency but if you are on a budget, vinyl is a good alternative too. Wooden sliding doors, on the other hand, are no longer as common as they come with their own set of challenges including being extra prone to water damage and warping.

    How To Install A Patio Door

    Patio Door Installation Transforms an Outdoor Space ...

    One of the best ways to transform a gloomy family room or kitchen is by installing a new patio door.


    If you are an experienced do-it-yourselfer with excellent carpentry skills, the project can be accomplished in a weekend.

    In addition to the new patio door, you will need wood shims, roofing paper, drip edge flashing, silicone caulk, nails and screws, interior molding, and molding for the outside edge of the threshold. Your toolbox will likely already contain a hammer, level, drill with screwdriver bit, flat pry bar, and circular saw.

    Start by purchasing a door suitable for your climate and situation. If you have severe winters, be sure to get thermally insulated glass. Low-e coating on the glass limits the passage of heat, keeping your room cooler in summer and warmer in winter. Also, be sure the door seals tightly when closed and that the weatherstripping is durable. If you plan to keep the door open in the summer, see that the screen door seals tightly as well. For more, see Patio & Sliding Doors Buying Guide.

    Once you get your new patio door home, here is how to install it:

    Literature that comes with your door will tell you the exact size of the required opening. Make sure your opening is very close to perfectly square: Use a level to check the sides for plumb and the top and bottom for level.

  • Replacing A Patio Door

    If you have a backyard deck or patio, chances are there’s more than an ordinary door connecting your outdoor space with the inside of your home. In contrast to the traditional porch, decks and patios are real living spaces that extend both the form and function of your home’s interior. And while we’d all like to keep the nasty weather outside where it belongs, we’d like to do so in a way that brings the spaces together as part of a whole. And the usual way is with a patio door.

    The classic patio door fits a double-wide opening and is made up of two aluminum-frame glass panels–one fixed and the other sliding. While the actual opening isn’t that much bigger than an ordinary door, the broad expanse of glass across the two panels creates a feeling of spaciousness and helps connect the indoors and outdoors in a visual way.

    It’s not unusual, though, for older sliding patio doors to show their age. The rollers and tracks are subject to wear, making operation difficult. Handles may break and latches may become misaligned. Add to this the wide range of styles available to replace your old sliding unit, and the project begins to look attractive.

    Removing The Old Unit Full-glass patio doors are heavy and it makes sense to disassemble the old unit and remove it in pieces. While sliding patio units vary in design and assembly, here’s the removal process we followed.
