New seamless eavestroughs custom-extruded on site for London’s heritage homes, clay-soil lots, and Forest City leaf load. Replacing worn sectional systems or equipping new builds with a drainage system sized for Southwestern Ontario’s freeze-thaw winters. 40-year no-clog warranty. Free estimates.
London sits on Catfish Creek till and London clay — dense, low-permeability soil that holds surface water rather than absorbing it. When an eavestrough overflows or discharges too close to the foundation, that water has nowhere to go quickly. It pools against basement walls, builds hydrostatic pressure, and drives the seepage and efflorescence that homeowners across Old South, Byron, and the Thames River floodplain see every spring and after summer downpours. An undersized or deteriorating eavestrough system on a London lot is not a cosmetic problem — it is a direct path to basement water infiltration and foundation movement.
The solution is a correctly sized seamless eavestrough system with downspouts extended a minimum of 1.8 metres from the foundation onto a positive surface grade — or tied into a buried French drain where the lot allows. Oversized 6-inch K-style profiles are the right choice for London homes with steep rooflines or large drainage areas; standard 5-inch K-style suits most post-war and newer bungalows. Getting the sizing right from the start prevents the overflow events that load London’s clay soil with water it cannot shed fast enough.
Sectional eavestrough systems — the pre-cut lengths snapped together with pop-rivets and lap sealant — are common on London homes built before 2000. Every mid-run seam is a future leak. London’s freeze-thaw cycle opens those seams year by year: temperatures crossing 0°C dozens of times between November and March expand and contract each joint, progressively failing the sealant bond. Once the seam opens, water tracks behind the fascia board, softens the wood, and eventually requires fascia replacement at a cost that dwarfs the original eavestrough installation.
Already have a section that’s failed rather than a full replacement situation? Our London eavestrough repair service handles isolated joint resealing, rehang, and downspout replacement at a fraction of full replacement cost.
Every London installation uses material sized for the specific home and roofline — extruded on site from coil stock, not cut from pre-made sections. Our roll-forming machine produces runs of any length in a single continuous piece, without the waste or field-seam risk of standard-length sections.
The standard for most London homes — handles typical roof runoff volumes for bungalows and two-storeys in Hyde Park, White Oaks, and Masonville. Available in over 30 colours. Hidden-hanger or exposed-spike profiles depending on roofline clearance.
Recommended for London homes with steep rooflines, large drainage areas, or lots prone to overflow. The right choice for larger heritage properties in Old North and the Old South Heritage Conservation District where high roof pitches generate substantial per-storm runoff volumes.
The historically appropriate profile for London’s Victorian, Edwardian, and Craftsman heritage homes in Wortley Village, Old North, and the Richmond Street corridor. Half-round eavestroughs self-clean more effectively than K-style and match the roofline character of century homes throughout London’s heritage conservation districts.
The premium choice for high-end restorations and heritage properties where aluminum would be historically out of place. Copper develops a natural patina, never requires painting, and outlasts aluminum by decades. Welded corner seams for a permanent watertight joint on any London heritage home.
50-micron aluminum mesh prevents the compacted maple, oak, and linden debris that blocks Forest City eavestroughs within a single autumn. Installed flush with the roofline. A 40-year no-clog warranty is included on every EavesArmour installation in London.
Self-regulating heat cable installed inside the eavestrough and downspout prevents ice dam formation during London’s freeze-thaw-heavy winters. Lake Erie and Lake Huron squalls regularly bring mid-winter thaw-refreeze events that crack downspouts and dam eaves without proper protection.
Every EavesArmour London installation follows a consistent process — from the first measurement to the final site clean-up. No subcontractors, no surprise costs, no leftover debris.
A certified technician measures every run on your London roofline, calculates the correct slope and downspout placement for your lot grade, and identifies any existing fascia rot, soffit damage, or drainage issues before quoting. You receive a written, itemized estimate with no obligation.
We confirm the right profile, size, and colour for your specific London home — K-style vs. half-round, 5-inch vs. 6-inch, aluminum vs. copper — based on your roof geometry, heritage status, and the surrounding canopy creating London’s exceptional debris load.
Our roll-forming machine travels with the crew and extrudes each run to the exact measured length on your property. No standard-length sections, no field seams, no left-over waste. Runs are formed, cut, and mounted in a single installation day.
Downspouts are positioned to drain away from London’s clay foundation soil — minimum 1.8 metres from the house on a positive grade. Where required, we route extensions around garden beds or suggest buried drainage solutions to keep your landscaping intact.
If gutter guards are added — strongly recommended in the Forest City — micro-mesh panels are installed in the same visit, flush-fitted to the new eavestroughs before we leave. One visit, one warranty, one clean result.
Every installation ends with a complete site clean-up: all old eavestrough sections removed, fascia board inspected and reported, grounds swept. Your technician walks you through the finished installation and confirms the warranty coverage before leaving.
The cost of eavestrough installation in London depends on the linear footage, roofline complexity, number of downspouts, and whether gutter guards are added at the same time. Ranges below reflect standard seamless aluminum. Heritage profiles, copper, and larger K-style carry an additional premium. For the full Ontario pricing picture, see our eavestrough installation cost Ontario guide.
$1,100 – $2,000
Approx. 100–160 linear feet, 2–3 downspouts. Common across White Oaks, Oakridge, and older Hyde Park bungalows on standard London lots.
$1,900 – $3,200
Approx. 160–240 linear feet, 3–4 downspouts. Typical of Masonville, Fox Hollow, Summerside, and newer South London subdivisions.
$2,800 – $4,800+
240+ linear feet, complex rooflines, or custom-matched heritage profiles. Common on large Old North and Wortley Village heritage homes and estate properties in Byron and Riverbend.
All pricing is estimate only. Final cost is based on an on-site measurement. Adding London gutter guard installation at the same time adds $600–$1,500 depending on footage and guard model, with no additional mobilization cost.
London’s exceptional leaf load — silver maples, red oaks, American lindens, and elms dropping simultaneously in October, with a maple samara surge every late spring — means a new eavestrough without a guard is a short-term solution. Most Forest City homeowners who install seamless eavestroughs and skip the guards call us back within two seasons to clean a packed trough or repair a sagging section overloaded by wet debris. Installing EavesArmour micro-mesh at the same time as the eavestrough costs less than a single future cleaning visit, and it eliminates cleaning for the 40-year life of the warranty.
See our EavesArmour micro-mesh gutter guard system for full product details, or our eavestrough cleaning service for existing systems that need clearing before installation.
Our roll-forming machines travel to every London job site. Each run is extruded on your property to the exact measured length — no standard sections, no field seams, no off-cuts. The result is a seamless system that fits your roofline perfectly without compromise.
Every installation paired with EavesArmour micro-mesh guards carries a 40-year no-clog transferable warranty — backed by the manufacturer, transferable to the next owner of your London home. The warranty covers debris ingress, not just material defects.
EavesArmour technicians are certified installers and the company is fully insured for all work across Ontario, including London and Middlesex County. We pull permits where required and leave every London site cleaner than we found it.
We understand London’s clay-soil drainage requirements, the heritage profile requirements of Old North and Wortley Village, and the exceptional debris volumes that the Forest City’s mature canopy creates. Every system is sized for the specific home, not a generic template.
We never push replacement when repair is the smarter investment. If your London eavestrough only needs a joint resealed and a hanger replaced, our technician will tell you that on the first visit — and put it in writing. See our London eavestrough repair page for repair-only service.
Most London installations are scheduled within the same week. Emergency replacement after storm damage or a section pulling away from the fascia is typically booked within 48 hours, weather permitting.
EavesArmour installation crews work across all of London — from century heritage homes in Old North and Wortley Village to newer subdivisions in Fox Hollow and Summerside. Most areas have same-week availability for installations.
Also serving Westmount, Fox Hollow, Summerside, Argyle, Pond Mills, and surrounding Middlesex County communities including St. Thomas, Strathroy, and Dorchester. See all service areas →
Eavestrough installation in London typically runs $1,100 to $2,200 for a standard bungalow and $1,800 to $3,500 for a two-storey home, depending on linear footage, corner count, and material. Seamless 5-inch K-style aluminum is the most common choice across London’s suburban stock in Hyde Park, Byron, and White Oaks, while heritage properties in Old North and Wortley Village often need a custom-matched half-round or wider K-style profile, which can add $200 to $500 to the base cost. Downspout extensions routed around London’s clay-heavy lots to a proper drainage point are quoted separately. EavesArmour provides free on-site estimates — you know the full cost before any work starts. For Ontario-wide pricing context, see our eavestrough installation cost Ontario guide.
London sits on thick Catfish Creek till deposits and London clay — a dense, low-permeability soil that expands when wet and contracts when dry. Rain water that misses an undersized or overflowing eavestrough puddles at the foundation for hours or days because it cannot penetrate the clay quickly enough. That sustained surface contact drives hydrostatic pressure against basement walls and is a major contributing factor to the seepage and efflorescence that homeowners across Old South, Byron, and the Thames River valley see after heavy rain events. Correctly sized seamless eavestroughs — combined with properly extended downspouts routed at least 1.8 metres away from the foundation onto the surface grade — are the first and most cost-effective defence against London’s clay-soil drainage problems.
Seamless eavestroughs are custom-extruded on site from a continuous coil of aluminum — the only joints in the finished system are at inside corners and downspout outlets. There are no mid-run seams. London’s freeze-thaw cycle is one of the most aggressive in Southern Ontario: temperatures cross 0°C dozens of times between November and March, driven by the moderating-then-intensifying influence of Lake Erie and Lake Huron weather systems. Each cycle expands and contracts a metal seam, progressively opening the joint until it leaks. Removing those mid-run seams eliminates the most common failure point on older sectional systems, extending the effective life of the eavestrough by years. For London’s Forest City leaf load, seamless also means there are no joint lips inside the channel to catch maple samaras and compact debris.
Yes. EavesArmour installs eavestroughs throughout London — from century-old brick homes in Old North, Wortley Village, and the Old South Heritage Conservation District to post-war bungalows in Oakridge and Westmount, and newer builds in Masonville, Hyde Park, Fox Hollow, and Summerside. Our crews carry on-board roll-forming machines that extrude seamless runs to the exact measurement required on your roofline. We also serve surrounding communities including St. Thomas, Strathroy, Dorchester, and Middlesex County at the same rates.
In London, yes — pairing installation with micro-mesh gutter guards at the same visit is almost always the right call. The Forest City lives up to its name: silver maples, red oaks, American lindens, and elms drop an exceptional two-wave debris load every fall, and maple samaras arrive in late spring as a second blockage event. Without protection, a brand-new eavestrough on an Old North or Byron lot can be packed solid within a single autumn. EavesArmour’s 50-micron aluminum mesh integrates flush with the new eavestroughs, carries a 40-year no-clog warranty, and eliminates cleaning for the life of the system. Installing both at the same time also reduces total labour cost compared to separate visits.
A new eavestrough system is most valuable when paired with the right protection. Most Forest City homeowners add micro-mesh guards and a gutter guard system at the same installation visit.
Micro-mesh guards stop the maple seeds, oak debris, and linden leaves that cause repeat clogs on Forest City rooflines.
