Leaking joints, sagging sections, freeze-cracked downspouts — EavesArmour diagnoses and fixes eavestrough problems fast across all London neighbourhoods, from Old North heritage homes to Byron and Masonville subdivisions. Written workmanship warranty. Free estimates.
London earned its “Forest City” nickname honestly. Thousands of mature silver maples, red oaks, American lindens, and elms line streets from Old South to Masonville — and every October they shed simultaneously, dropping dense, wet leaf mats that can pack a standard eavestrough solid within a week. Combined with London’s inland snowbelt winters — hard freeze-thaw cycles driven by Lake Erie and Lake Huron squalls — eavestroughs here face some of the harshest conditions in Southern Ontario. Every freeze-thaw cycle expands and contracts metal joints, progressively opening seams and fatiguing hanger screws. Compacted leaf debris adds weight to aging hangers and turns spring snowmelt into foundation-directed overflow. A small joint leak caught early costs a fraction of the fascia rot or basement seepage it eventually causes.
Old sealant cracks under London’s freeze-thaw cycles. Dripping joints soak the fascia board and begin rotting the wood behind the eavestrough within a season or two — especially on the north faces of heritage brick homes in Old North and Wortley Village.
Hangers loosen after years of thermal expansion and heavy leaf load. Sagging eavestroughs pool standing water, accelerate rust, and eventually pull the trough off the roofline entirely — leaving the fascia exposed to every rainstorm and freeze.
A freeze-cracked downspout sends melt water behind the siding and into the wall cavity. This is particularly common on the north-facing walls of London’s older Old South and Richmond Street heritage homes after a hard January cold snap.
The Thames River valley concentrates spring melt across London’s lower neighbourhoods. When compacted maple and oak debris blocks the trough, water spills over the edge and saturates the foundation perimeter — a recurring problem in Byron and Old North.
Ice dams form when blocked eavestroughs trap snowmelt that refreezes at the roof edge. London’s mid-winter thaw cycles make this a recurring risk on homes with lower-pitched roofs across Masonville and Hyde Park subdivisions.
Rust streaks running down siding below the trough mean the aluminum or steel has corroded through. Affected sections need replacement, not patching — rust spreads quickly once it starts and is especially common on London homes over 25 years old.
Our service trucks carry matching aluminum profiles, downspout components, hangers, sealant, and end caps for the most common London eavestrough repairs — most jobs are finished in a single visit with no parts delay.
Clean old sealant from the joint surface, prime, and apply new long-life butyl or silicone sealant. The most common London repair — a single leaking seam is typically done in under an hour. Particularly common on 1970s and 1980s sectional systems throughout Westmount and Oakridge.
Replace worn or pulled hangers with concealed-fastener brackets at correct spacing and re-slope the run so water drains properly to the downspout. Common on Forest City homes where heavy leaf debris has added chronic weight to the hanger system over many seasons.
Cracked or missing end caps let water shoot sideways off the roofline onto siding and into soffits. We carry matching aluminum end caps in the standard Ontario colour palette for a flush, watertight finish.
Full or partial downspout replacement including elbows, straps, and extensions. Freeze-cracked downspout sections are one of the most frequent winter service calls across London and Middlesex County.
Fix or replace cracked outlets and elbows where the downspout meets the trough — a common source of hidden wall leaks on century homes with brick or stone exteriors throughout Old North and the Richmond Street corridor.
When corrosion or impact damage is too severe to seal, we cut and splice in a new matching segment secured at both ends. Custom-profile matching is available for heritage homes in London’s Old North and Old South conservation districts.
When your existing system is beyond economical repair — or when you’re building new — EavesArmour installs seamless aluminum eavestroughs custom-fabricated on site to your roofline. Seamless construction eliminates the mid-run joints that cause most of the leaks we repair on older sectional systems — the only seams are at inside corners and downspout outlets.
We source wide-profile 5" and 6" K-style aluminum in 30+ colours to match any London exterior.
Pairing new eavestroughs with London gutter guard installation at the same visit protects your investment from day one and eliminates cleaning for the life of the system. See our full eavestrough installation service page for more details on materials and profiles.
The right answer depends on the age of your system, the material, and how widespread the damage is. We give you an honest assessment rather than defaulting to the more expensive option.
If replacement is the right call, EavesArmour can also add micro-mesh gutter guards at the same time to eliminate future clogging. See our full Ontario eavestrough repair page for general pricing and service details.
Most eavestrough repairs will eventually come back without the right protection in place. London’s exceptional leaf load — the heaviest of any city EavesArmour serves — means even a freshly repaired system will clog again within a single autumn season without a quality guard. Our 50-micron micro-mesh aluminium system blocks maple samaras, linden seeds, oak catkins, and wet leaf fragments while maintaining unrestricted water flow year-round. A lifetime no-clog warranty is included on every EavesArmour installation in London.
Micro-mesh guards stop the maple seeds, oak debris, and linden leaves that cause repeat clogs on Forest City rooflines.
Our flagship 50-micron aluminium mesh system with a lifetime no-clog warranty — the standard on London installs.
EavesArmour ICE self-regulating heat cables stop London’s freeze-thaw ice dams before they crack your eavestroughs.
When repair is no longer cost-effective, we replace with a custom-fabricated seamless aluminium system on site in London.
EavesArmour repair and installation crews operate across all of London — from century heritage homes in Old North and Wortley Village to newer Hyde Park and Masonville subdivisions. Most areas have same-week availability.

Genuine Forest City expertise, a written workmanship warranty, and honest repair-vs-replace advice — not just the most expensive option.
Our crews know the heritage profiles of Old North, the debris volumes of Byron’s mature canopy, and the ice-dam risk on Masonville’s lower-pitched rooflines. We custom-fit every system rather than forcing standard-size guards onto non-standard eaves.
Every eavestrough repair and installation comes with a written workmanship warranty. If something we touch fails, we come back and fix it — no arguments, no service fees.
We never default to the more expensive option. Our technicians give you a frank assessment based on the age, material, and actual damage to your system — and put the recommendation in writing before any work begins.
Most London service calls are booked within the week. We confirm 24 hours in advance, arrive in a marked vehicle, and clean up completely before we leave.
London’s exceptional canopy — silver maples, red oaks, lindens, and elms — creates one of Ontario’s highest debris volumes. Our 50-micron micro-mesh is purpose-built for exactly this environment.
London sits in Southwestern Ontario’s snowbelt corridor. Our Eavesarmour ICE self-regulating heat-cable system prevents ice dam formation at the roof edge through London’s freeze-thaw-heavy winters.
Eavestrough repairs in London typically range from $100 to $475 depending on the scope of work. Joint resealing at a single seam runs about $100–$150. Rehinging a sagging run costs $150–$275 per section. A complete downspout replacement — including elbows, straps, and an extension — is usually $175–$350. Homes in heritage neighbourhoods like Old North and Wortley Village may cost slightly more if non-standard profiles need sourcing, as the tall elms and lindens in those areas accelerate debris compaction and fastener fatigue. EavesArmour provides free, no-obligation on-site estimates so you know the exact cost before any work begins.
London sits in Southwestern Ontario's snowbelt corridor, catching lake-influenced squalls off Lake Erie and Lake Huron. Temperatures cross 0°C dozens of times between November and March — each freeze-thaw cycle expanding and contracting metal joints, progressively opening seams and fatiguing the hanger screws that hold the trough against the fascia. Add the Forest City's legendary leaf load: silver maples, red oaks, American lindens, and elms drop dense, wet mats from Old North to Byron every October. That debris compacts in blocked troughs, adds significant weight to aging hangers, and turns spring snowmelt into a foundation-directed overflow. A joint leak caught early costs a fraction of the fascia rot or basement seepage it prevents.
Yes. We repair aluminum, vinyl, galvanized steel, and copper eavestroughs across all of London's housing stock — from narrow-fascia century homes in the Old North Heritage Conservation District and Wortley Village to standard K-style troughs on the newer Masonville, Hyde Park, and White Oaks subdivisions. Our service trucks carry matching aluminum profiles, downspout components, end caps, sealant, and hanger hardware, so most London repairs are completed in a single visit with no parts delay.
Many repairs are completed year-round in London, including rehanging sagging sections, replacing cracked downspout components, and clearing ice-compacted debris blockages. Butyl or silicone sealant applications perform best above 5°C — during London's colder periods we apply a temporary sealant that holds until a permanent repair can be completed in spring. We always advise the most appropriate approach for current conditions and never leave you with an active leak going into the rest of winter.
Repair is usually the right call when damage is limited — a leaking seam, a loose hanger, or a cracked end cap — especially on systems under 15 years old. Replacement makes more sense when a system is 20-plus years old, shows widespread rust or corrosion along multiple runs, or has an incorrect pitch that causes chronic pooling. On older London homes near Richmond Street or the Old South neighbourhood, we often find aluminum that is structurally sound but needs a full re-slope and new concealed-fastener hangers rather than an outright replacement. Our technicians give you an honest recommendation — we never push replacement when repair is the smarter investment.
