We've heard every version of these problems. Here's what homeowners call an exterior door installer about most often.
This happens when an installer hangs a pre-made frame without inspecting whether the rough opening underneath is level and square. The door often sticks, drags, or drafts within a year because the frame was never sitting correctly to begin with. We start every job with a full opening inspection before anything new goes in.
Some installers quote a stripped-down scope that excludes disposal, framing repair contingency, or a labour warranty, then add those as extras once work begins. This leaves homeowners with a final bill well above the original number. We itemize every quote up front so nothing is a surprise later.
Skipping flashing above the frame or using the wrong foam type leaves gaps that let in drafts and eventually water. The homeowner usually does not notice until the next season brings colder weather or heavy rain. We follow a full sealing sequence on every installation, no exceptions.
Vague or evasive answers about what a warranty actually covers usually mean the coverage is thin or nonexistent. This becomes a real problem if something goes wrong after the invoice is paid. We explain our workmanship guarantee clearly before any contract is signed.
Forcing a pre-hung frame into an opening that is out of square creates a door that never closes evenly, no matter how the hardware is adjusted afterward. This is one of the most common signs of an unqualified installer. We correct the framing before setting the new door rather than forcing a fit.
A door that fails early almost always points back to installation quality rather than the product itself. Frame separation, drafts, and sticking that appear within a couple of years are signs the original install cut corners. We back every installation with a workmanship guarantee that reflects our confidence in the work.
A long list of nearby installers makes it hard to know who actually does quality work versus who just shows up first in search results. Proximity alone does not predict skill. We recommend checking licensing, insurance, and references before proximity when narrowing the list.
Hesitation to provide references, especially from jobs completed more than a year ago, is often a sign the installer's work does not hold up over time. Recent references alone do not show long-term performance. We are glad to connect homeowners with past clients whose doors are still performing well.
A quote well below others in the same market is often missing steps that only become apparent once the old door is removed. Choosing based on price alone can mean paying more later in repairs. We provide itemized, honest quotes that reflect the full scope of the work involved.
I got three quotes and Ontario Door & Window Pros was the only one that itemized everything clearly. No surprise charges once the old door came off. The installer explained exactly what he was checking before starting.
Our previous installer never checked the framing and the door had been sticking for two years. This crew found rot in the sill immediately and fixed it properly. Door closes like it should for the first time in years.
The installation itself was excellent and the crew was clearly experienced. Had to wait about a week and a half to get on the schedule, but the quality made up for it once the work started.
I asked about licensing, warranty, and what happens if the frame needs repair, and the installer from Ontario Door & Window Pros answered all of it without hesitation. That confidence made the decision easy.
It has been over a year since installation and the door still closes exactly like it did on day one. No drafts, no sticking, nothing. Exactly what we hoped for after a bad experience with a previous installer.
Ontario Door & Window Pros walked us through exactly what drove our quote before any work began. When they found a minor framing issue, they explained the cost before proceeding instead of surprising us on the invoice.
