Installing Massive Doors & Flashing: A Day of Problem Solving and Precision Work ( Morning Preparations and Flashing Installation)
We arrived on site ready to tackle one of the more challenging aspects of this build – installing oversized doors with proper weatherproofing. The day began with examining our materials, including a new type of flashing above the deck band. “It’s a different color – is there anything different about it besides the color?” I asked Jamie as we unloaded supplies.
“I think it’s a composite material now,” Jamie replied, though neither of us were entirely sure what that meant for performance. The darker tone was Immediately preferable to the gray we usually had to paint black to match our aesthetic. As Max marked measurements, we discussed the critical importance of installing this flashing before the door pan flashing. “The door pan needs to overlap this section,” Jamie explained. “Trying to tuck it underneath later would be nearly impossible.”

This attention to sequencing is what separates a quality installation from future headaches. We’ve learned through experience that proper layering of waterproofing elements makes all the difference in preventing moisture intrusion that could lead to rot and structural damage down the line.
Inspecting and Removing the Dining Room Door ( Installing Massive Doors & Flashing: A Day of Problem Solving and Precision Work )

Moving to the dining room door, we encountered our first major task. The wood-clad door (with an aluminum exterior) promised better performance than vinyl alternatives. “I have a vinyl slider at home,” I shared with the crew, “and when it’s cold outside, the temperature difference makes the door bow inward. It becomes nearly impossible to slide until temperatures stabilize.”
The solid wood frame of this unit should maintain its rigidity regardless of weather conditions. But before we could install it, we needed to remove the existing fixed panel – no small feat given its 500-pound weight. After locating some cleverly hidden screws and utilizing a small tool pack we found inside the door frame, we began the delicate extraction process.
“Ready? One, two, three—lift!” The panel came free with surprising ease once we understood the mechanism. “Don’t lose that spacer block,” Jamie cautioned as we carefully maneuvered the massive component out of the opening. This kind of teamwork is essential when handling heavy building materials – one wrong move could mean damaged finishes or worse, injury.
Door Opening Preparation: The Devil’s in the Details
With the opening cleared, we turned our attention to preparing the subfloor. “This step might seem minor,” Jamie noted as he ran a level across the threshold, “but if the bottom of the door opening isn’t dead flat, the threshold will conform to whatever shape exists here.”

Our inspection revealed a swollen strip along the edge where water had pooled over time. “This is exactly why we spend so much time on flashing details,” I remarked as Jamie outlined his solution: complete removal of the compromised section and replacement with new material. The team worked efficiently, using oscillating tools to make precise cuts and ensure a perfectly flush surface for the new door. The flashing installation that followed demonstrated Jamie’s meticulous approach. He applied Lexel sealant generously along all seams and edges. “These are probably $10,000 door units,” he reminded us. “We get one shot to install them correctly.” The overlapping flashings created a waterproof barrier that would protect the rough opening for decades.
The Door Installation Challenge

With preparations complete, we moved the new door into position. Removing the shipping skid revealed the bottom rail construction – only the outer inch and a half was solid material, with the rest being hollow extrusion. “This is why we doubled up on the Lexel bead,” Jamie pointed out as we carefully lifted the unit into place.
Initial fitting revealed an unexpected issue – the floor wasn’t as level as we had assumed. “No way is the floor level,” Jamie insisted when we struggled to get the door plumb. A quick check with the level proved him right. This kind of discovery is why we never skip verification steps, even when we’re confident in our work.
Using strategic shimming and careful adjustment, we brought the door into perfect alignment. The satisfying “click” of the locking mechanism engaging confirmed our success. “That’s butter-smooth operation,” Jason remarked as we tested the sliding action.
The Accordion Door Puzzle

Our next challenge was significantly more complex – a 12-foot-wide accordion-style door system. Before diving in, we took a field trip to examine a similar installed unit at Rock and Alexis’s honeymoon suite. Seeing the mechanism in action proved invaluable.
The track is surprisingly narrow – only about 2 inches wide,” Jamie observed as we examined the hardware. Back at our site, unboxing revealed another puzzle: “How does a 12-foot track come in an 8-foot box?” The answer was four 6-foot sections that would need precise alignment during installation.
The lack of instructions (beyond a cryptic FedEx label mentioning “AIS”) forced us to rely on intuition and collective experience. We identified critical details like the weep hole orientation (“Definitely want this facing outward unless you like water inside your house”) and developed a system for the tedious assembly process.
Problem-Solving Under Pressure
The installation presented multiple hurdles:
- Hardware Challenges : The provided stainless steel screws required deep pilot holes in dense yellow pine. “I’m terrified this will snap halfway in,” I admitted as we debated pre-drilling strategies.
- Track Alignment : Getting the multi-section track perfectly straight required creative bracing and constant verification.
- Magnetic Latches : Discovering hidden magnets in the packaging meant last-minute modifications to the beautiful cladding.
Each obstacle required patience and teamwork. When the final panel slid smoothly into place, the satisfaction was palpable. “That’s why we get paid the big bucks,” Jason joked as we admired our handiwork.
Lessons Learned and Looking Ahead
This day encapsulated what makes construction so rewarding and frustrating:
-Preparation is Paramount: Taking time to properly flash and level saves countless headaches later.
–Teamwork Multiplies Success: Heavy doors and complex mechanisms require coordinated effort.
– Flexibility is Essential: When instructions are lacking, experience and creativity fill the gaps.
As we packed up tools, we reflected on the remaining challenges. The accordion door, while mostly complete, still needed final adjustments. “Tomorrow we’ll tackle the trim details,” Jamie said, already planning the next phase. Another day, another opportunity to turn problems into solutions.
