Siding & roofline
"Seamless aluminum gutters installed on the full house. D&D ran proper slope checks and the downspout extensions are positioned perfectly to drain away from the foundation. No more basement moisture."

Eavestrough Replacement and Installation
Review eavestrough and downspout work as a complete roofline request, including existing condition, discharge arrangements and related repairs.
The meeting of shingles, trim and drainage.
A coordinated finish for the roofline
New eavestroughs connect the roof edge to downspouts and the discharge route below. They are also a visible exterior detail, with profile and colour choices that can sit quietly alongside the fascia or define the roofline.
Follow the water path
Corners, outlets and downspout positions influence how runoff leaves the building. Replacing only the most visible length may leave a restricted outlet or an awkward discharge location unchanged.
The supporting edge matters
Loose gutter sections or stained fascia can signal related work at the roof edge. Sound fixing surfaces are important when deciding which components can remain and which need replacement.
One coordinated proposal
Removal, new troughs, downspouts and fascia repairs can be separate parts of the project. Bringing them together in the quote helps avoid a finished gutter installation with unfinished adjoining details.

Siding & roofline
"The crew noticed my existing fascia board was rotting behind the old eavestrough and flagged it before installation. Got it repaired at the same time. That kind of thorough work is rare."

"Used D&D across four properties for eavestrough replacement. The seamless gutters look sharp and the leaf guard on the tree-side runs has basically eliminated cleaning calls."

Questions about Eavestrough Replacement and Installation
Does overflowing always mean larger gutters are needed?
No. A restriction, outlet problem, damaged section or discharge arrangement may be involved. Describe when and where the overflow occurs so the connected components can be assessed before a replacement specification is chosen.
Should downspouts be included in the quote?
Yes, their status should be clear even if they remain. A new trough connected to an unsuitable or damaged downspout can leave part of the original problem outside the work.
Can gutter work reveal fascia damage?
Staining, loose fixings or removal may expose a supporting repair. Ask how such conditions would be documented and authorised, and keep the fascia work separate from the agreed new gutter components.
Can the discharge be moved to a different location?
Discuss the proposed route with the surrounding grades, paths and site requirements. A convenient outlet should not be selected without considering where the water then goes and any separate review required.
Will gutter replacement solve basement water entry?
It may address part of the roof-water route, but basement water can have other causes. Treat the observed entry as a separate assessment question rather than accepting a gutter installation as a whole-building waterproofing guarantee.
How should colours and profiles be compared?
Compare the actual trough, downspout, corner and adjoining fascia finishes together. Ask which sections will remain visible so a small replacement does not create an unexpected mismatch along the roofline.

Eavestrough Installation in Kitchener-Waterloo
D&D Exterior Finishing installs seamless aluminum eavestrough systems throughout Waterloo Region. Eavestroughs are your home's primary defence against water damage — directing rain and snowmelt away from your foundation, preventing basement flooding, and stopping erosion around your home's perimeter. When they fail, the consequences are expensive.
Why Proper Eavestrough Matters for Ontario Homes
Waterloo Region receives significant annual precipitation, and our winters add the challenge of snowmelt that can overwhelm undersized or clogged eavestrough systems. A failing eavestrough allows water to pool against your foundation — the leading cause of basement water infiltration in the region. D&D Exterior Finishing installs seamless aluminum systems with correct pitch, adequate hangers, and proper downspout sizing to handle Waterloo Region's precipitation loads.
Types of Eavestrough We Install
01
5" K-Style Seamless Aluminum
The standard choice for most Ontario homes, 5-inch K-style aluminum eavestrough is formed on site from coil stock — completely seamless except at corners and downspout connections. Seamless construction eliminates the #1 source of eavestrough leaks: section joints.
02
6" K-Style Seamless Aluminum
Homes with steep roofs, large roof areas, or in high-rainfall zones benefit from the greater capacity of 6-inch K-style eavestrough. The wider trough and larger downspouts handle significantly more volume during Ontario's heavy rain events — preventing overflow that can damage landscaping and saturate the foundation.
03
Seamless Gutters
All eavestrough we install is seamless — formed on site with a portable roll-forming machine that extrudes continuous lengths to exactly fit your roofline. Unlike sectional gutters purchased at a hardware store, seamless gutters have no mid-run joints to leak, separate, or allow debris accumulation.
04
Gutter Guards
Gutter guards prevent leaves, seeds, and debris from accumulating in your eavestrough — eliminating the need for seasonal cleaning. We install micro-mesh and reverse-curve guard systems that allow water to enter freely while keeping organic debris out, reducing maintenance to virtually zero.
Our Eavestrough Installation Process
- Measure & Assess — We measure your roofline, assess the fascia condition (repairing any rot before installation), and determine the correct eavestrough size, downspout locations, and drainage outlet points for your property.
- Remove Old Eavestrough — Existing eavestrough and hangers are carefully removed. Fascia is inspected and any damaged sections are repaired before new hangers are installed.
- Form & Install Seamless Eavestrough — New seamless sections are formed on site to exact lengths using our roll-forming machine. Eavestrough is hung with hidden hanger brackets at 24-inch spacing and pitched toward downspouts at the correct grade for positive drainage.
- Downspout Installation & Drainage — Downspouts are installed and directed away from the foundation. Extensions and splash pads are positioned to ensure water drains at least 6 feet from the house — preventing foundation saturation.
Why Waterloo Region Homeowners Trust Us
- Formed On Site — Always SeamlessWe never install sectional eavestrough. All gutters are roll-formed on site to exact lengths — no mid-run joints, no leaks.
- Fascia Inspection IncludedBefore hanging new eavestrough, we inspect and repair the fascia backing — so the system has a solid foundation and your warranty is meaningful.
- Correctly Pitched Every RunWe pitch every eavestrough run at the correct grade toward downspouts. Standing water in gutters leads to rust, pest attraction, and ice dam formation — we eliminate it by design.
- Proper Downspout SizingWe size downspouts to match the eavestrough width and roof area draining into each section — ensuring the system can handle Waterloo Region's peak rainfall rates.

Frequently Asked Questions About Eavestrough
How much does eavestrough installation cost in Kitchener-Waterloo?
Eavestrough costs depend on linear footage, gutter size (5" vs. 6"), number of downspouts, and whether gutter guards are added. D&D Exterior Finishing provides free, written estimates. Contact us for a quote specific to your home.
Is D&D Exterior Finishing licensed and insured for eavestrough work?
Yes. We are fully licensed and insured for eavestrough installation in Ontario, WSIB compliant, and experienced in seamless aluminum systems for all home types.
Do you offer a warranty on eavestrough installations?
Yes. All eavestrough projects include our workmanship warranty. Aluminum material warranties vary by coil stock supplier. Details are in your written estimate before work begins.
How long does eavestrough installation take?
Most full eavestrough replacements on a standard home are completed in one day. Larger homes or those with complex rooflines may take two days.
Do you serve my area for eavestrough installation?
We install eavestrough throughout Kitchener, Waterloo, Cambridge, Guelph, Elmira, Ayr, New Hamburg, Baden, Woodstock, Brantford, Breslau, and surrounding communities.
Should I choose 5-inch or 6-inch eavestrough?
For most standard-sized Ontario homes with conventional roof pitches, 5-inch K-style eavestrough is sufficient. We recommend upgrading to 6-inch for homes with steep roofs (higher water volume per square foot), large roof areas over 1,500 sq ft per section, or locations with significant tree cover that increases debris and water channelling. We'll assess your specific roof during the free estimate and make an honest recommendation.
Are gutter guards worth it in Ontario?
For most Waterloo Region homeowners with mature trees nearby, yes — gutter guards significantly reduce the frequency and difficulty of eavestrough cleaning. Maple keys, oak leaves, and pine needles are the most common cloggers in our area. A quality micro-mesh guard system pays for itself in avoided cleaning visits within 3–5 years. We'll give you an honest assessment of whether guards make sense for your specific property.
