As a homeowner in Oshawa, ON, you know how important it is to protect your property from water damage. One of the most overlooked yet critical components of a home’s exterior is the eavestrough system—also commonly referred to as gutters. While regular gutter cleaning and maintenance can extend their lifespan, eavestroughs do not last forever. Knowing when to replace your eavestroughs can save you from costly roof repairs, foundation issues, and interior water damage.
At The Eavestrough Guy, we specialize in roofing, gutter cleaning, and eavestrough installation in Oshawa and surrounding areas. In this guide, we’ll help you recognize the top warning signs that your eavestroughs need replacing and explain what to do next.

Why Eavestroughs Matter More Than You Think
Before diving into the signs, it’s important to understand what eavestroughs actually do. These narrow troughs collect rainwater from your roof and channel it safely away from your home’s foundation. Without a properly functioning system, water can:
Pool around your foundation
Leak into your basement
Damage your landscaping
Rot fascia boards and roof sheathing
In short, functioning eavestroughs are essential to your home’s structural integrity.
How Long Do Eavestroughs Typically Last?
The lifespan of eavestroughs depends on the material and maintenance. On average:
Aluminum gutters: 20–25 years
Steel gutters: 15–20 years
Copper gutters: Up to 50 years
Vinyl gutters: 10–15 years
That said, exposure to harsh weather, poor installation, and infrequent cleaning can reduce their lifespan significantly. That’s why routine inspections and professional cleanings are key.
Top Signs Your Eavestroughs Need Replacing
Let’s explore the most common signs that it’s time to replace your eavestroughs. If you notice any of these issues, don't ignore them.
1. Sagging or Pulling Away from the Roofline
If your gutters are visibly sagging, separating from the fascia, or pulling away from the roof, it means they are no longer securely attached. This usually happens due to:
Rotting fascia wood
Broken fasteners
Water weight from clogs or standing debris
In some cases, reattachment may solve the problem. But if the gutters are bent, damaged, or misaligned, a full replacement may be necessary.
2. Cracks, Holes, or Rust Spots
Small cracks or holes might seem harmless at first, but over time they expand, allowing water to leak directly onto your siding or foundation. If you see multiple rust spots or corrosion—especially on steel gutters—that’s a definite sign that your eavestroughs are nearing the end of their life.
Even if you attempt DIY patching, you’re only delaying the inevitable. The better long-term solution is a professional replacement.
3. Peeling Paint or Water Stains on Exterior Walls
Paint that bubbles or peels off the wall underneath your gutters is often a sign of chronic water leakage. Similarly, if you notice dark streaks, mildew, or water stains running down the exterior siding, this could mean that your eavestroughs are leaking or overflowing.
This is often one of the earliest warning signs that homeowners notice.
4. Water Pooling Around the Foundation
Perhaps one of the most dangerous outcomes of faulty eavestroughs is foundation damage. If you find puddles near the base of your home after a rainstorm, it means that water isn’t being properly diverted.
When this happens consistently, it can:
Erode your foundation
Cause basement flooding
Promote mold and mildew growth
Replacing your eavestroughs promptly can prevent these costly consequences.
5. Plant Growth or Pest Infestation in the Gutters
If your eavestroughs have become home to weeds, moss, or even small trees, it’s a clear sign that water isn’t flowing properly. Similarly, nests from birds, rodents, or insects can block water flow and add weight, causing gutters to sag or break.
Although professional gutter cleaning might solve this short-term, heavy infestation often means the system has already suffered internal damage.
6. Overflowing Gutters During Rainfall
Take a look during the next heavy rain. If you see water spilling over the sides of the eavestroughs, it's either due to a blockage or the gutters being too shallow, misaligned, or damaged.
Overflow can erode landscaping, damage siding, and lead to interior leaks—making it a problem you can’t afford to ignore.
7. Basement Dampness or Mold Growth
Have you noticed a musty smell or damp spots in your basement? Faulty gutters might be the culprit. When water pools near your home and seeps downward, it can infiltrate the lower levels, causing:
Wall discoloration
Mold patches
Foundation cracks
Replacing damaged eavestroughs ensures rainwater stays out of your basement—where it belongs.
8. Gaps at the Joints or Separated Sections
Modern eavestrough systems are designed to be seamless or have tightly joined sections. If you notice visible gaps, separated joints, or frequent leaks, it's time to consider a full replacement.
Persistent leaks between joints can erode walls and roofs, making your system unreliable.
Should You Repair or Replace Your Eavestroughs?
Not every problem means a full replacement is necessary. Sometimes, minor issues like a single dent or loose bracket can be repaired. However, widespread damage, multiple leaks, or rusted metal generally means replacement is the smarter, more cost-effective route.
If you're unsure, the team at The Eavestrough Guy offers professional inspections and honest recommendations based on the condition of your system.
