How to Replace a Sliding Patio Door Step-by-Step

Whether your patio door has seen better days or you want a new, stunning gateway to the outside, replacing your sliding door makes it easier to enjoy your yard, patio or other spaces.

Choosing a New Patio Door

Before you select your new sliding door, know what you’re looking for. Consider these factors so you choose a fixture that fits your space and meets your needs:

• Size: Remove your existing door’s casing and measure between the studs, as well as from the top of the opening to the bottom, to determine your door’s measurements.
• Material: Choose materials that complement your living space’s aesthetics while offering durability to withstand years of use, especially in high-traffic areas.
• Features: Select options or add-ons like protective finishes and functional hardware to ensure your sliding door fits your style.

How to Replace a Patio Sliding Door in 10 Steps

If you want to replace your sliding door, you’ll need to follow several steps for a secure fit:

1. Square the opening and ensure the sill plate is level.
2. Finish preparing the opening with shims, a drip edge and caulking before placing the sill pan.
3. Position the door in the opening and use shims 1 foot apart across the top for a secure fit and under screw holes for longevity.
4. Install hinges or other hardware.
5. Use finishing nails spaced approximately 1 foot apart inside and outside the door to hold the framing to the molding.
6. Screw the threshold into the door, being careful to fully sink the screws.
7. Cut the shims until flush with the frame, and use insulation to fill gaps before applying trim.
8. Caulk between the trim and interior wall.
9. Caulk around the exterior casing with a paintable product.
10. Spackle any nail holes.

Considering a Professional Patio Sliding Door Replacement

Patio doors are large, so removing your existing ones to position, secure and seal the new door can be a challenging and complex DIY project. The process requires careful preparation, placement, leveling and finishing, so hiring a professional can help you get the best results. An expert’s knowledge and attention to detail can prevent future issues and save time compared to installing your sliding door on your own.

How Much Does It Cost to Replace Sliding Patio Doors?

The most significant factors in the cost of replacing sliding patio doors are the price of your new doors and whether you hire a professional.

If you choose to install your sliding patio doors yourself, you’ll need to buy additional supplies such as caulking, foam insulation, finishing nails and spackle. You may also need tools like a drill, a level and utility or putty knives. You’ll pay for labor if you hire a professional to install your replacement. Add-ons like decorative fixtures also affect the project’s total cost.
