Install The New Doors

Regardless of the type and size of the door and what materials its made from, each set of doors will come with its own instructions. To prepare for the installation work, the window fitter will use string to ensure that the opening is straight and plumb both in a vertical and horizontal direction.

On each side of the frame, the string should be attached to all corners. A perfect X shape should be achieved with the strings crossing over one other, proving that the opening is just right. Lastly, its time to ensure that the floor is level. Shims and packers can be used if its not.

In order to seal rough parts of the opening, outdoor calk or a similar water-resistant sealant must be applied. The opening should be given time to dry before moving onto the next phase of the installation.

Once the opening has dried, the doors should be slid into the bottom threshold, and a rubber mallet may be used to gently tap them into position. If the doors are pre-hung in the frame, then a second set of hands will certainly be needed to put them into place. Shims/packers can be used to make the doors level if needed.


At this point, the installers will test the doors to check that they open and close smoothly. Now, its time to fix the frame into position. Per the manufacturers instructions, nails or screws can be employed to achieve this.

Remove The Existing Structure

On the day of the installation work, the first practical step will be to remove what is currently present. This might mean removing existing doors, an existing window, or making a new opening by knocking down part of a wall.

Assuming that, more than likely, existing doors are being removed, this will start with the removal of the hinges. Next, the frame should be removed before the opening is checked to ensure that it is clean and smooth.

If its not, then some old elements like rotting timber should be replaced.

What Should I Look For When Buying A Patio Door

There are a range of patio door ideas to choose from, depending on desired aesthetics, thermal performance and security.


‘The most obvious factor is how the doors look and perform,’ says Edward from IDSystems.

‘Looking at the system in person is vital, so you get an understanding of exactly what it is youre ordering. There are lots of systems on the market that might look similar in pictures, but its only when you get up-close and see how the doors operate that youll be able to get a feel for the quality and usability.’

The desired functionality of the doors comes into play, too. ‘Within the same opening, you can get more of a clear opening with French or folding doors.

On the other hand, you can achieve a greater viewing area in a sliding door due to the typically thinner profiles that allow for more glass,’ says Brent Wright, doors product manager at Milgard.

Dont forget to consider the interior layout of the space, either. ‘For instance, a sliding door doesnt require any space beyond the opening, whereas a swinging door needs space to open into,’ continues Brent.


Before setting your heart on a product, establish what kind of threshold you want. For example, if youre keen to create a sleek, flush transition from inside to out, this needs to be factored in at the start of the project, before the doors are ordered. This allows for the adequate preparation of the aperture.

Always check the systems weather rating with your supplier before placing your order.

Patio Door Replacement Costs

The desire for upgrades or need to repair damage may lead you to consider replacing all or part of your existing patio door.

All costs below include a price between $100 and $300 for disposal of waste and existing materials, typically quoted as part of the overall replacement cost.

Securing And Installing Trim

After ensuring that the door is sitting level to the frame, secure them in place. Using three fastening nails into each of the jambs should be enough to properly secure them. If you used shims, make sure to nail them into the frame or jambs accordingly.


Now, its time to place insulation to fill in the cracks that exist along the jambs. The best insulation should fill in those spaces without having to be forced to do so and will ensure that your French doors are efficient.

Finally, install the trim kits or the old trim over the frame. The trim will cover the insulation and provide a more pleasant aesthetic, bringing your project to completion.

Use the long level and carpenter’s square to make sure the inside of the opening is square and true.

Bring the door up to the opening for installation, sliding the bottom of the door in first. To check square, measure diagonally from corner to corner of the frame. Also check for plumb with a level.


Remove The Stationary Panel

  • Pry the stationary panel free of the frame at the top and bottom, slitting caulk or paint as necessary with a utility knife.
  • Tip it inward and lift it free.
  • Pry off the exterior trim.
  • Use a reciprocating saw with a longer bimetal blade to cut between the framing and the door jamb.
  • You will cut through the insulation, fasteners and shims.
  • With the head and side jambs cut free, tip the frame from the top to the outside.
  • 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.
    • Flexible flashing comes in 4- to 6-in.-wide rolls and has a sticky side so it adheres to the underlying surfaces.
  • It’s imperative that the flashing laps well over any or weather barrier below the door.
  • You may have to overlap two rows to get the necessary coverage.

    How To Fit French Doors

    Whilst fitting French doors isn’t as complex or involved as installing other external or internal doors. But it’s a task you’ll want to undertake with a little help. Also, it’s definitely not for DIY newbies. If you feel like this is you, it would pay to look for an experienced professional or asking the manufacturers themselves for advice. Whether you’re installing interior or exterior French doors, you’ll need a decent set of tools. Also, don’t forget your safety goggles!

    Interior If you’re installing internal French doors, first, remove the old frame with your hammer and pry bar. As you’re doing so, be careful not to damage the trim. This is not a job you want to rush. You’ll need to use a fair amount of force, but if you overdo it you’ll need to redo the trim, which will be pricey. Next, make sure your opening is perfectly square using your square and level. If it’s not 100% square, but is workable, get your sanding paper out.

    If it’s wonky, you might want to consider calling in a professional to even it out. Next, using the instructions supplied with the kit, install it in the opening using shims to keep it held securely in place. Before you screw the frame in, pick up the doors and place them gently in the frame, making sure they both fit and open smoothly. You’ll want a helper for this part!

    How To Install Self Adjusting Spring Hinges

    MIWD French Rail Patio Door Handle Removal and Installation

    Every screen door NEEDS to slam, or at least self close. So I learned there are hinges with springs inside them. Better yet, you can even pick up adjustable spring hinges, meaning, you can adjust how tight you want the springs for the right slamming effect. SOLD!


    I googled on the right placement for the hinges, and penciled them in at 6 down from the top of the door and 9 from the bottom of the door.

    The brackets were held at the right placements, then I made pencil marks through the holes.

    Each hole was predrilled. This saves your wood from splitting, plus makes building easier.
