Top 7 Reasons Your Solarium Is Leaking (And How to Fix It)

 



By a technician at Alumwave


“It Started With a Drip…”

It usually begins like this: you're relaxing in your solarium during a rainstorm, enjoying the view—until you hear it. Drip... drip... drip. You look up, and there it is—a tiny leak creeping down the wall or collecting on the window sill. It may seem small now, but left alone, it can turn into stained walls, warped floors, mold, or even structural damage.

As someone who's been up on a lot of ladders and inside more than a few leaky sunrooms, I can tell you—solarium leaks are common, but they’re never something to ignore. Let’s break down the top seven reasons they happen and how our team at Alumwave tackles each one with lasting solutions.


1. Worn-Out Seals Around Glass Panels

The problem: Over time, the rubber seals or caulking around the glass panels start to dry out, crack, or shrink. This creates small gaps where water can seep through.

What to watch for: Water running along the inside of the frame, or dripping during heavy rain.

How we fix it: We remove old, deteriorated sealant and replace it with UV-resistant, high-grade exterior caulking—specifically designed for solarium systems.


2. Cracked or Shifted Glass Panels

The problem: Settling foundations, extreme temperature shifts, or even a hailstorm can cause glass panels to crack or move out of alignment. Once that happens, the integrity of the system is compromised.

What to watch for: Visible cracks, fogging between panes, or water coming in along one section.

How we fix it: We assess the damage and replace the affected panel with a properly sealed, tempered safety glass—custom-fit to your solarium structure.


3. Failed Flashing

The problem: Flashing is the material that bridges the gap between your solarium and the house. If it’s installed incorrectly or has corroded over time, it can direct water into your home instead of away from it.

What to watch for: Leaks along the wall where the solarium meets the home, especially after wind-driven rain.

How we fix it: We remove the old flashing, assess the structural connection, and install new weatherproof flashing with proper overlaps and water flow direction—sealed tight to prevent future failure.


4. Improper Sloping or Drainage

The problem: If your solarium roof or window tracks aren’t sloped correctly, water can pool instead of draining off, eventually finding a way inside.

What to watch for: Standing water, especially near roof joints or window sills.

How we fix it: We realign drainage channels or adjust the slope where possible. In some cases, we retrofit improved drainage components, like weep holes or flashing extensions.


5. Old Gaskets or Structural Components

The problem: Over time, gaskets (the rubber or foam inserts between glass and frame) break down, especially with sun exposure and age. Older solariums may have materials that are no longer effective.

What to watch for: Persistent leaks during rain, especially in multiple spots.

How we fix it: We inspect all framing and gasket conditions, then upgrade to modern, high-durability gaskets designed for long-term water resistance.


6. Loose or Corroded Fasteners

The problem: Screws, bolts, and brackets that hold the frame together can loosen or corrode, leaving gaps for water to sneak through.

What to watch for: Small drips around frame connections or signs of rust.

How we fix it: We replace corroded fasteners with rust-proof stainless steel and apply waterproofing sealant over each joint for extra protection.


7. Improper Past Repairs

The problem: Unfortunately, we often find that past repairs were done with quick fixes—like duct tape, indoor caulking, or poor-quality materials. These don’t hold up and can even make things worse.

What to watch for: Leaks in spots that have clearly been patched before.

How we fix it: We remove all temporary fixes, assess the underlying issue, and apply permanent solutions using the right materials and installation techniques. At Alumwave, we always aim for a long-term fix, not a band-aid.
