Get Picky About Your Exterior Door Components

Exterior doors are an important part of any home…

They create a first impression for guests and welcome families home at the end of each day. They provide protection from intruders, pests, and the elements, and keep the air inside comfortable no matter the weather or season. Homeowners want exterior door systems that match their unique style and protect what matters most – without having to think about of fuss over maintenance and repairs down the line.

Exterior door components are a crucial element in determining the performance capabilities of any door. Exterior door components are small parts that don’t get a lot of attention – but these small components play a huge role in determining the performance of your doors. Choosing the right exterior door components can make or break the level of maintenance required of install teams during construction, as well as service required down the line.

..And when calculating the true total cost of any door.

So when considering the components used in your exterior door systems, it’s important to remember: you get what you pay for. Sure, saving a few bucks upfront sounds nice, but when that few bucks of savings turns into an average of $150 of service costs per door down the line, you’re only adding more costs to your company’s bottom line and more pressures on your labor force.

“Whether it’s adjusting adjustable door sills to eliminate daylight under the door, making adjustments to correct French door leaks, cleaning or repairing a damaged sill decks, or in some cases, even replacing the entire door threshold or door unit – standard components come at the price of a pretty costly to-do list.”

Plus, when you consider that early stages of frame rot can begin within 3 months and most warranties cover at least a full year, that’s yet another potential repair to add to your list. If rot occurs after the initial warranty period and the homeowner is left to deal with it – it could be your name and reputation that get put on the chopping block.

Exterior Door Frames & Frame Components

Rot-Proof Exterior Door Components

Wood rot is a naturally occurring fungus which grows in moist conditions and feeds on wood fibers. While many think of moisture damage and rot as issues which develop over time, door frame rot can begin as soon as 3 months after installation.

The signs of frame rot:

  • Water Wicking
    Wood fibers naturally absorb water. Homeowners may notice a musty smell and crumbling sections in the door frame.
  • Swelling
    Shrinking and swelling occur as wood changes moisture content. This is in response to daily/seasonal changes in the relative humidity of the atmosphere.
  • Paint Peeling
    If water is left standing on the sills, it can eventually penetrate the paint film. Later, when the water evaporates, the pressure from under the film causes paint to blister and peel.

Unless preventive steps are taken, it only takes about 3 months for wood rot to set in. Most homes are under warranty for a year, which means you could be paying for as many as 4 service calls before the warranty is up! This is a big cost for you and a hassle for your customers.

The composite frame that’s also an installation system.

Traditional composite exterior door frames boast a maintenance-free installation, but are saddled with performance issues that limit their usage. Thermal bowing and bending are a major problem that affects composite frames in areas that experience extreme heat and cold. On the other hand, solid wood frames are prone to rot and moisture damage and require regular maintenance or replacement.

FusionFrame combines the maintenance-free aspects of a composite door frame and the structural rigidity of a wood frame into one product that delivers everything you want from an exterior door frame and nothing you don’t.

FrameSaver® by Endura offers unmatched protection from rot. Unlike full PVC-composite which is flimsy and doesn’t finish like wood, and treated wood which only delays the onset of rot, FrameSaver® is the industry’s original rot-proof wood frame. The composite piece is finger-jointed into the wood to enhance the structural integrity.

Sills and Sill Systems

Many homeowners face issues such as leaks or cold air drafts inside their homes and don’t realize how their door sill plays a critical part in preventing these problems. A tight seal makes a home more energy efficient and protects against leaks and insects.

Why does my door sill need to be adjusted?

The sill is important to maintaining a perfect seal that blocks cold air, dust, water, and insects from entering a home. Visible light beneath a door, cold air drafts, and even water leaks are all tell-tale signs a door sill may need adjusting. Having a properly adjusted sill maintains a comfortable indoor temperature and reduces monthly energy costs.

Z-Articulating Cap SillTM

New ADA 4916 - Standard Cap 2copy

ADAptive is an ADA-compliant door sill system that does more and goes further, delivering improved performance as the first and only ADA-compliant sill that boasts a DP-20 water rating, as well as unmatched versatility and a simplified assembly in the shop.

The Replaceable Deck Sill™ (RDS) enables you to overcome sill damage by quickly and easily remove and replace a damaged or discolored deck without the need to remove the sill or door unit. With RDS, your sill will go from damaged to done in a fraction of the time and money it would take to clean or repair a traditional sill, or in some cases replace your entire door system.

The Z-Articulating Cap Sill™ (Z-AC) is a self-adjusting sill, eliminating the need to maintain and modify because it automatically adjusts every time the door is closed, creating a perfect seal every time. This sill prevents the performance issues a traditional adjustable sill can have, including “stuck” doors or sills without a tight enough seal to protect the house from air loss and leaks, making it a cost-effective solution for any home.

The Z-Series Adjustable Inswing Sill is made with synthetic components that protect against discoloration, warping, and dents for long-lasting protection and performance. It can be easily adjusted to tighten or loosen the seal between the sill and the door as needed. Endura’s modular design offers the ability to use repositionable inactive caps to create a variety of multiple opening door units from the same SKU.

Essential Weathersealing Components

Proper weathersealing is an essential part of exterior door installation and offers lasting protection from these common issues:

  • Water leaks
  • Loss of heating and cooling
  • Cold air drafts
  • High humidity and moisture levels

Investing in quality exterior door components for proper weathersealing will allow you to prevent those common issues and offer better, more energy efficient homes your customers will appreciate.

Corner Pads and Seals

Corner pads can be considered one of the most important parts of a door when it comes to sealing out air and preventing leaks. This small part can lead to big problems if it’s missing, including frame rot, leaks, and drafts.

Simple Solution®️ Corner Pad

The Simple Solution®️ Corner Pad is designed to work against the upward pressure that can force water around weatherstripping during a thunderstorm or other heavy weather conditions. It fits in the “crucial corner” of a door system and forms a tight seal around the sill, panel, and frame.

Simple Corner

The Simple Corner works with a door’s weatherstrip to block the passage of water and air. Easy to install, it fits behind the weatherstrip at the upper corners of a door system.


Weatherstripping is designed to seal those little cracks between your door and the frame that don’t quite seal when the door is closed. These gaps can account for up to 30% of heating or cooling loss in a house each year, so having quality weatherstripping can be an unexpected selling point.

A good weatherstrip will conform to the door when it’s closed, and spring back into shape when it is opened. Over time, a weatherstrip may begin to crack, bend, and become ineffective as it’s exposed to water and daily wear and tear.

Endura Weatherstrip is made to last. Made with a cellular lite foam and a polyurethane liner, it’s designed to wick 50% less water, resulting in a dependable, long-lasting seal.

Keep your customers happy and build something you can stand behind when you power your doors with products by Endura. Our exterior door components provide unmatched quality, security, and protection for homes, allowing builders and contractors to cut costs on service calls and give their customers maintenance-free homes with doors that are built to last.
