The patio door sill is a piece of trim that sits at the bottom of your door. It’s important to replace this piece if it has rotted, as you may have water leaking into your home and rotting the flooring below. In this write-up, we discuss how to replace a rotted patio door sill so you can protect your home from leaks.
There are a few different aspects to replacing a rotted patio door sill. The first and most important aspect is the type of sill it is, and what material it’s made from. It means determining its thickness and length, for example.
If you do not know the measurements, you may need to remove, preserve, and reinstall the rotted patio door sill as close as possible to its original location to determine this information accurately.
Next, determine if that width or thickness can be secured using an existing wall surface – either through one of the supports at each end (meaning it will stay parallel with your wall) or through an intermediary support beam mounted somewhere within your mudroom.

Can Rotted Patio Door Sills Be Restored Without Being Replaced?
Yes, it is possible to restore rot without replacing the door. The process will involve:
• Removing the rotten materials.
• Stabilizing the sill with an appropriate cement or epoxy.
• Reinstalling any necessary hardware.
Rot can be remediated by filling the rot with an epoxy-putty filler designed to provide structural bonding and stability. The filler provides a stable, waterproof tissue membrane to protect the sill from additional moisture damage while preparing for the next steps.
When Should you Replace a Rotted Patio Door Sill?
The Patio Door sill should be replaced immediately if it’s deteriorated beyond repair, cracked, warped or hanging.
Usually, replacing the patio door sill is required after a few years because rotting wood is not safe to walk on. The fix can be costly depending on severe damage caused by water and weather. Luckily property owners have options for repairing and replacing, including Plastic Waterproofing or more traditional techniques such as Harwood or PVC Sills that requires cutting and installing new pieces.
Those with rotting patio doors sills must first determine whether they want to fix their existing porch door sills and then find solutions for those who don’t want to put up any more money to fix something so battered looking as rotten wood.
How To Replace a Patio Door Sill?
There are a few ways to do this. You can either buy a new sill, or you can make a new one out of wood. If you choose to make a new one out of wood, you will need to measure the width and depth of the old sill, then buy lumber that is the same size. Cut the lumber to fit, then use a power drill and screws to attach it to the bottom of the door frame.
You might be able to get away with just replacing the sill without having to replace the door itself. The easiest way to do this is to remove the screws that hold the sill in place, then pry it out using a putty knife or screwdriver.
Once the old sill is out, measure it and cut a new one to size using a circular saw. Make sure the new sill is level, fit it into place, and then reattach it with the screws.
What Causes Patio Door Sills To Rot Faster?
It’s been found that dirt and sediment from rain colliding with a patio door sill can worsen the problem.
When water gets on a patio door sill, it can erode the wood by causing corrosion of metal screws and rot from fungal deterioration.
It also accelerates grass seedling growth, interfering with opening or closing a door.
Metal framed doors surrounding a wooden sill will often rust at the joints, leading to greater vulnerability to corrosion and resultant rotting of surrounding wood due to moisture collection beneath and an admission source for insect larva such as carpenter ants, termites etc.
When the moisture levels in the air are high, for instance, during large rain events or dewpoints (temporarily high moisture levels), wood siding is more likely to contract and expand. This shrinking and swelling process will eventually cause it to break down, leading to rot.
Flooding can also result in localized deterioration because water supplies hoses fungus, deteriorating the wood. Additionally, improperly draining roof runoff can create pools of water, promoting soil erosion and damaging fascia boards leading to eventual sagging gutters that snow gathers on top of until it’s pushed off due to weight or brushes against them when hanging off a ladder.
How To Ensure Your Patio Door Sill Lasts Longer?
You can do a few things to help your patio door sill last longer. First, make sure to keep it clean by sweeping it regularly. You should also apply a sealant or weatherproofing product to the sill every few years to help protect it from the elements. Finally, check for cracks or damage occasionally and repair them as soon as possible.
