"New steel front entry door installed last month. D&D measured three times, the fit is perfect, and the draught seal is noticeably better than the old door. House feels warmer already."

Door Installation and Replacement
Discuss exterior door installation or replacement with the opening, frame, hardware and finishing requirements considered together.
A sliding opening set into brick.
An entrance that opens, closes and fits properly
A replacement exterior door can update the entrance and address worn components. The result depends on the whole opening: door, frame, threshold, weather seals and hardware.
The door and frame work together
A sticking door or visible gap can have more than one cause. Replacing the slab alone may not resolve a damaged frame or an opening that needs correction.
Light, privacy and everyday use
Glazing brings daylight into the entrance, while panel style and hardware influence appearance and operation. The best combination fits how the door is used, including the clearance needed around it.
Finishing the opening
Interior trim, exterior capping and adjoining repairs affect what the completed installation includes. A quote should make those finishing boundaries clear alongside the selected door and hardware.
Location planning and service coverage

"Had three patio sliding doors replaced. The install team was careful with the interior trim and left everything cleaner than they found it. The new doors glide perfectly."

Questions about Door Installation and Replacement
Can only the door slab be replaced?
A limited replacement depends on the existing frame, hinges, hardware and opening condition. Have compatibility assessed; a new slab alone may leave the reason for dragging or poor closing unchanged.
Will a new door fix every draft at the entrance?
Drafts can involve seals, the frame or the connection to the surrounding wall. Review the whole opening and proposed installation details rather than treating the door panel alone as the complete solution. Natural Resources Canada: windows and exterior doors
Can I keep my lock and handles?
Provide the exact hardware and identify what you want retained. Dimensions and fitting requirements may differ between door products, so confirm compatibility before ordering rather than relying on a similar appearance.
What should I consider when choosing glazing?
Balance daylight, privacy and the entrance's actual use with the proposed product documentation. Review glass and frame details together, especially where a sidelight or a different opening arrangement is being considered.
Are interior trim and exterior capping included?
Ask for each finishing boundary to be stated. Removal or a different frame can expose adjoining areas, and an assembly-only quotation may not cover the work required to leave both sides finished.
How do I prepare an occupied entrance?
Clear the immediate work area and discuss people, pets and deliveries that use the door. Confirm alternative access and the work arrangements directly; do not assume a proposed visit leaves the entrance continuously usable.

Door Installation & Replacement in Kitchener-Waterloo
D&D Exterior Finishing installs and replaces exterior doors throughout Waterloo Region. A properly installed door is essential for security, energy efficiency, and curb appeal. Our team ensures every door hangs perfectly plumb, seals tightly against Ontario winters, and operates smoothly for years to come.
Why a Properly Installed Door Matters
A poorly hung door is more than an annoyance — it's a security risk, an energy drain, and a source of moisture damage to your threshold and framing. In Waterloo Region's climate, door frames are subjected to extreme temperature swings that cause expansion and contraction. D&D Exterior Finishing installs every door with proper shimming, flashing, and weatherstripping to ensure a tight, lasting seal in any season.
Types of Doors We Install
01
Entry Doors
Your front door is the first thing visitors see — and the last line of defence against intruders and the cold. We install fibreglass, steel, and wood entry doors in single, double, and sidelite configurations, including insulated foam-core models that dramatically reduce heat loss.
02
Patio Doors
Sliding and French patio doors connect your home to your outdoor living space. We install multi-point locking patio doors with thermally broken frames and triple-pane glass options — maximizing your view while keeping heat in and cold out all winter long.
03
Storm Doors
A storm door adds an extra layer of insulation and protection to your entry door — extending its life, improving energy efficiency, and keeping insects out in summer. We install full-view aluminum storm doors built for Ontario's demanding climate.
04
Garage Doors
An insulated garage door is one of the highest-ROI upgrades for Waterloo Region homes — improving curb appeal while reducing heat loss in an attached garage. We supply and install steel-panel and carriage-style garage doors with insulation ratings suited to Ontario winters.
Our Door Installation Process
- Free Measure & Estimate — We measure your existing opening precisely, assess the condition of the framing and threshold, and provide a written estimate for the door and installation together — no surprises.
- Frame Preparation — The old door and frame are removed. We inspect and repair any rot or water damage in the rough opening, replace the sill if needed, and install proper flashing tape before the new unit goes in.
- Door Setting & Adjustment — The new door unit is set plumb, level, and square, shimmed at all hinge and latch points, and fastened securely to the structural framing.
- Weatherstripping, Caulking & Trim — All gaps are filled with foam insulation, exterior caulk is applied, and trim is reinstalled or replaced. We test the door operation, locking, and seal before completing the walkthrough.
Why Waterloo Region Homeowners Trust Us
- Threshold & Framing Repairs IncludedWe address rot and water damage at the threshold during installation — not as a surprise add-on on invoice day.
- Plumb & Level Every TimeA door that isn't perfectly set will bind, draft, and fail prematurely. We take the time to shim and adjust every unit to exact tolerances.
- Hardware & Lock AlignmentWe adjust all hardware and test multi-point locks before sign-off. You'll never have a door that won't latch properly after a D&D install.
- Same-Day CompletionMost door replacements are completed in a single day, leaving you with a secure, weathertight home every night.

Frequently Asked Questions About Doors
How much does door installation cost in Kitchener-Waterloo?
Door installation costs vary based on door type, size, and the condition of your existing frame. Contact us for a free written estimate with no surprise charges.
Is D&D Exterior Finishing licensed and insured for door installation?
Yes. We are fully licensed, WSIB compliant, and carry comprehensive general liability insurance for all door work in Ontario.
How long does door installation take?
Most single door replacements are completed in half a day. Double doors and patio doors typically take a full day. Garage door installations are usually completed within one day as well.
Do you offer a warranty on door installations?
Yes. All door installations include our workmanship warranty plus the manufacturer's product warranty. Your estimate will clearly detail all warranty coverage before work begins.
Do you serve my area for door installation?
We install doors in Kitchener, Waterloo, Cambridge, Guelph, Elmira, Ayr, New Hamburg, Baden, Woodstock, Brantford, Breslau, and surrounding communities.
Should I choose a fibreglass or steel entry door?
Both are excellent choices for Ontario homes. Steel doors are slightly more affordable and very secure, but can dent and may show rust over time without proper maintenance. Fibreglass doors are dent- and rust-proof, extremely energy-efficient, and available in wood-grain finishes. For most Waterloo Region homeowners, fibreglass is the long-term winner.
Can you repair a door that's sticking or drafting instead of replacing it?
In some cases, yes — a door that's sticking due to seasonal swelling or minor frame movement can often be adjusted. However, if the issue is a rotted threshold, failed weatherstripping, or a warped door slab, replacement is usually more cost-effective. We'll give you an honest assessment during the free estimate.
