About D&D Exterior Finishing
Skilled tradespeople who take pride in every exterior — built on a foundation of certified craftsmanship, honest communication, and work that's guaranteed for 25 years.
Our Story
Built by Tradespeople Who Saw Homeowners Get Burned
D&D Exterior Finishing was founded in 2023 by Devon Moore and David Fitzpatrick after years of witnessing Waterloo Region homeowners suffer costly consequences from hiring generalist contractors who lacked the specialized knowledge to properly install exterior cladding, flash a roofline, or build a code-compliant deck. Improperly installed siding creates moisture pathways into wall cavities. Poor roofline flashing leads to ice dams and water infiltration. These aren't cosmetic issues — they're structural problems that cost tens of thousands of dollars to remediate, often discovered only after serious interior damage has already occurred.
We set out to build a company that specializes exclusively in exterior renovation — nothing else. Every member of our crew is trained on the specific installation requirements of the manufacturer products we carry. We pursue certification programs through CertainTeed, Gentek, BP Roofing, IKO, Ply Gem, Trex, and Duradek so that when we install a product, we understand not just how to fasten it but why each detail matters to the entire system's long-term performance in Ontario's demanding freeze-thaw climate.
Today, D&D Exterior Finishing serves homeowners, builders, property investors, and condo boards across Kitchener, Waterloo, Cambridge, Guelph, and the surrounding region. We've completed over 80 exterior renovation projects and maintained a perfect 5-star review record on Google — because we refuse to cut corners, we communicate proactively, and we back every project with a 25-year workmanship warranty that travels with the property on resale.

The Full Story
What Kitchener-Waterloo Homeowners Deserve From an Exterior Contractor
Before D&D Exterior Finishing was founded, Devon Moore and David Fitzpatrick spent time investigating dozens of exterior renovation projects in Kitchener-Waterloo that had gone wrong — not because of bad intentions, but because the contractors didn't have the technical depth to execute correctly. They found siding installed without proper house wrap integration, creating hidden moisture problems inside wall cavities. They found roofing jobs where the ice-and-water shield had been installed with inadequate overlap at the eaves — a ticking clock for water infiltration during the first major freeze-thaw cycle. They found decks built to dimensions that technically fit a permit but used fastener patterns that wouldn't hold up to Ontario's seasonal load cycles. The homeowners in every case had no idea anything was wrong until the damage had already become expensive.
What Devon and David recognized was that the solution wasn't simply better effort — it was deeper technical certification and a commitment to exterior-only specialization. A generalist contractor doing a bit of roofing alongside kitchen renovations and bathroom work will never develop the same depth of product knowledge as a crew that installs CertainTeed siding, BP and IKO roofing systems, and Trex decking every single day of the season. Manufacturer certification programs exist precisely to create that depth — and most contractors in Waterloo Region hadn't pursued them.
D&D Exterior Finishing launched with a simple promise to Waterloo Region homeowners: every product we quote is a product we're certified to install, and every installation follows the manufacturer's exact specifications so that your warranty is valid, your building envelope is properly protected, and the work will still look and perform exactly right in 15 years. Ontario's climate doesn't forgive shortcuts. We built this company around that reality — and our 25-year workmanship warranty backs up every word of it.
The People Behind the Work
Meet the Founders
D&D is built around two people who show up on every project and take personal accountability for the outcome.
Devon Moore
Operations Lead
Devon manages field operations, crew scheduling, material procurement, and on-site quality control across every active project. His hands-on approach means he's frequently on site verifying installation details personally. Devon holds certifications from CertainTeed, BP Roofing, and Trex, and conducts all structural assessments before any renovation begins. His background in construction project management ensures timelines and budgets are consistently delivered.
David Fitzpatrick
Client Experience Lead
David owns every client-facing interaction from initial inquiry through project completion and warranty handoff. He conducts all site visits, prepares detailed written quotes, and presents material and colour selections to homeowners. His commitment to clear, proactive communication is the reason D&D has maintained a perfect 5-star Google rating — clients always know where their renovation stands and what to expect next.
How We Work
Our Standard on Every Job
Four non-negotiable pillars that define every D&D Exterior Finishing project — regardless of budget or scope.
Certified Materials
We only install products we're certified on. No substituting lower-grade materials to protect a margin. What's in the quote is exactly what goes on your home — guaranteed in writing.
Precision Installation
Every installation follows the manufacturer's exact specifications — proper overlap, fastener spacing, flashing details, and weather barrier integration. We don't approximate; we follow the manual.
Clean Job Sites
We clean up at the end of every single workday. Scrap material, packaging, nails, and debris are removed before we leave. Project completion includes a full site walkthrough with the homeowner.
Guaranteed Work
Our 25-year workmanship warranty is documented in writing at project close and transfers with the property on resale. We stand behind every installation — if something we did causes a defect, we fix it.
What Drives Us
The D&D Difference
Exterior-Only Specialists
We don't do flooring, kitchens, or general contracting. Our sole focus is the building envelope — which means our crew's knowledge runs deep on every exterior system we install.
We Supply Our Own Materials
We purchase directly from manufacturers, not through middlemen. This gives us better pricing, access to full product lines, and the ability to guarantee authentic certified materials on every project.
Climate-Aware Installation
Ontario's freeze-thaw cycle is among the harshest in North America. Every system we install — from siding expansion gaps to roofing ice-and-water shield — is designed to perform through -30°C winters and humid Ontario summers.
No Subcontracting Core Work
Our core installation crews are D&D employees, not day-hire subcontractors. This means consistent quality, accountability, and tradespeople who take ownership of the work they put their name on.

Common Questions
Frequently Asked Questions About D&D Exterior Finishing
The questions homeowners in Kitchener-Waterloo ask us most often before booking a free quote.
Are you licensed for exterior renovation work in Ontario?
Yes. D&D Exterior Finishing holds an Ontario contractor licence for residential exterior renovation and carries $2 million in commercial general liability insurance. We also maintain current WSIB clearance. All documentation is provided before any work begins on your property.
Which areas of Waterloo Region do you serve?
We serve Kitchener, Waterloo, Cambridge, Guelph, and surrounding communities throughout the Waterloo Region and beyond. Our team is based in Kitchener and serves properties within approximately 60km. Contact us to confirm availability for your address.
What does your 25-year workmanship warranty actually cover?
Our 25-year workmanship warranty covers installation defects — meaning if something we installed fails due to improper installation technique, fastening, flashing, or system integration on our part, we return and correct it at no cost. This is separate from manufacturer product warranties, which we also help you register. The workmanship warranty is documented in writing at project completion and transfers with the property on resale.
How long have you been doing exterior renovations?
D&D Exterior Finishing was founded in 2023 in Kitchener, Ontario. We've completed 80+ exterior renovation projects across Waterloo Region, maintaining a perfect 5.0 Google rating throughout. Our founders Devon Moore and David Fitzpatrick are personally involved in every project from assessment through completion.
Do you require a deposit before starting work?
We require a materials deposit at the time of contract signing to secure your project timeline and purchase materials. The deposit structure is outlined clearly in our written quote before you commit. The remainder is due at project completion, after the final walkthrough confirms everything meets your expectations. We never request full payment upfront.
What We Believe
Our Core Values
Three principles that define how we approach every exterior renovation project in Waterloo Region — from the first free quote to the 25th year of warranty coverage.
Built Tough — No Material Shortcuts
We specify and install only the materials we're certified on — CertainTeed siding systems, BP roofing products, and Ontario Building Code-compliant assemblies. What's in your written quote is exactly what goes on your home. We never substitute to protect a margin at your home's expense.
Finished Right — Craftsman-Level Detail
Exterior renovation isn't about getting siding up fast — it's about getting every seam, flashing detail, corner trim, and fastener pattern exactly right. We follow manufacturer installation specifications to the letter, because precision installation is what separates a beautiful exterior that lasts from one that fails in year three.
Backed by Warranty — 25 Years of Accountability
Every D&D Exterior Finishing project closes with a written 25-year workmanship warranty that transfers on resale. This warranty isn't marketing language — it's a documented commitment we sign at project completion. If our installation causes a defect within that window, we return and correct it. Full stop.

Our Core Values
What every homeowner deserves — and what we deliver on every project.
Craftsmanship That Lasts
We select materials rated for Ontario's freeze-thaw cycles and install them to manufacturer specs — because a beautiful exterior that fails in three years isn't beautiful at all. Our standard is a finish that looks as good in year ten as it did on install day.
Honest Assessment
We tell you exactly what your siding, roof, or eavestroughs need — even if the answer is "not yet." No upselling work that isn't warranted. Our reputation is worth more to us than any single invoice.
Skilled Trade Every Time
All roofing, window, and siding installs are carried out by experienced tradespeople, not subcontracted labourers. Your project gets our best crew, every time.
Clear Communication
Written quotes, scheduled timelines, and regular photo updates. You'll never be left guessing about the status of your renovation.
Our Story
Built on referrals, grown through results — a decade-plus of making Ontario homes look their best.
Company Founded in Cambridge, ON
D&D Exterior Finishing began as a two-person siding and painting crew. Our first summer was fully booked on word-of-mouth alone — a pattern that's held ever since.
Roofing & Eavestrough Services Added
Clients asked us to handle their entire exterior envelope. We brought in certified roofers and eavestrough specialists, eliminating the need for homeowners to coordinate multiple trades.
Window Replacement Program Launched
Partnering with three Ontario window manufacturers gave us access to Energy Star-certified product lines and exclusive regional pricing — savings we pass directly to clients.
900th Home Milestone Reached
Surpassing 900 completed renovation projects, we expanded our team and service area across Waterloo Region, Brantford, and Hamilton to meet growing demand.
Community Involvement
Strong homes, stronger neighbourhoods.
D&D Exterior Finishing supports Habitat for Humanity Waterloo Region as a trade partner, providing volunteer crews for siding and roofing installations on affordable homes. Each year our team contributes a minimum of three project days, giving families safe, well-insulated homes they can be proud of.
We also run a seasonal "Neighbour Referral Discount" program where clients who refer a neighbour receive a credit applied to future maintenance work — keeping exterior renovation accessible while strengthening the communities we work in. Through our partnership with a local apprenticeship program, we host two to three co-op students annually, giving the next generation of trades hands-on exterior renovation experience.
Our Warranty & Process Promise
We back our work with written warranties and a clear project process — from first call to final walk-through. Every homeowner deserves to know exactly what they're getting and exactly what happens if anything falls short.
Free Site Assessment
Every project starts with a no-obligation site visit and detailed written quote — no ballpark estimates over the phone.
Written Scope of Work
Materials, timeline, crew size, and payment schedule agreed in writing before work starts. No surprises mid-project.
5-Year Labour Warranty
All installation work carries a five-year labour warranty. If something isn't right, we fix it — no argument, no charge.
Final Walk-Through Guaranteed
Every project closes with a client walk-through. Punch list items are resolved before we invoice the final payment.
All warranties are transferable to subsequent homeowners within the warranty period — a meaningful bonus when selling your home. Ask us for full warranty documentation at time of quote.
