Picture a scenario. Three companies come to your home to do a window replacement estimate. Two of the companies offer fairly similar quotes, but the third one, whether by means of discount, promotion or negotiation, provides you with a quote that’s several thousand dollars less. All three companies swear that their vinyl windows are of the highest quality and their window installers are the best in the city. Who are you most likely to go with?

Remember, you get what you pay for! This is a tired cliché, but it is especially true in home renovations. Yet we have to bring it up with bargaining customers over and over again when we get asked “why are your windows much more expensive than X, Y, and Z company’s?”

See, unfortunately, there are too many companies in our industry who benefit greatly from unsuspecting and unknowing customers. And while to you a window is a window, and even after it is installed you may not know the difference, there are numerous ways in which companies can leave you with a lesser product or workmanship.

How? Most often by withholding information, or passing it off for something it isn’t.

That package that costs several thousand dollars cheaper? Chances are, it is an insert/retrofit installation. Some companies simply don’t mention how your windows will be installed, hoping you haven’t done enough research to ask. Others may tell you that the installation will be of high quality, failing to mention what kind of installation it is in the first place. They do it to maximize their profit, without actually addressing the homeowner’s needs.

Full Frame and Insert Replacements don’t just look different, the installation process varies significantly between the two types.

In simple terms: in a full frame installation all the window parts get replaced down to the construction frame. The construction frame is also checked for damages, mold, or moisture. Your custom windows get outfitted with new brickmoulds, jambs, and trim. These vinyl components inside the window do not deteriorate over time and are easy to maintain and replace. These components are often a substantial part of the price in the full-frame replacement, but they also ensure a more thorough and proper installation.

In a retrofit replacement, all the window parts are left intact, only the glass and frame is replaced. The original wood stays around the window, and there is no checking of the construction frame. This can often leave the structure susceptible to moisture and rotting. The outside finish of the windows is often done with aluminum capping or caulking.

Insert installations do not address the issue in the wall structure. Rotten or deteriorating wood (pictured) may be left behind after the installation.

Retrofit installations are ideal for homes where the frames haven’t begun to deteriorate and aren’t showing signs of moisture damage or rotting. Even then, aluminum capping is a quite dated and a less than ideal solution for the longevity of your new windows. Capping can still allow moisture in, and the wooden frame underneath it is not allowed to breathe properly, making it susceptible to mold.

Aluminum cladding is a common exterior finish for insert windows. It looks significantly different from full frame replacements.

full_frame_vinyl_brick_mould

There are Canadian window companies that specialize only in full frame installations, and ones that do both kinds. Although we prefer full frame replacement because it is more thorough and there are fewer problems with it down the road, there are still instances when we recommend insert installation to our prospective clients.

Unlike other companies, we want to make sure our clients know exactly the kind of installation they are paying for, and exactly what they are getting.
