Replacing your windows involves more than choosing a new style. This window replacement guide covers how replacement windows are installed, the frame and glass options available, what can affect the project cost, and what to review before approving the work.
We’ll also explain what you can expect when planning a replacement project with Northwestern Exteriors Inc., from product selection and precise measurements through professional installation and final review.
Do Your Windows Need Replacing, or Just a Repair?
Not every window problem means you need a full replacement. Some issues can be repaired, while damaged or deteriorating windows may be better candidates for replacement. Our guide to the signs it’s time for home window replacement covers the warning signs to look for and when repair may still be an option.
If replacement is the right choice for your home, the next decision is how the new window will be installed. The two common approaches are insert replacement and full-frame replacement, and the condition of the existing window and frame can help determine which is more appropriate.
Insert vs. Full-Frame Window Replacement
Insert and full-frame replacement are two common approaches to replacing residential windows. The main difference is how much of the existing window assembly is removed.
An insert replacement, also called a pocket replacement, fits the new window within the existing frame. The existing frame and surrounding trim generally remain in place, making this a less extensive installation in many cases. Because the replacement window fits inside the existing frame, the finished glass area may be slightly smaller.
A full-frame replacement removes the existing window and frame, exposing the original opening. Depending on the project, interior or exterior trim and other surrounding materials may also need to be removed. This approach provides access to the original opening and can offer more flexibility when changing the window’s size or configuration.
The choice between the two can affect the installation scope, cost, finished glass area and how much of the existing opening is exposed.
| What To Consider | Insert (Pocket) | Full-Frame |
| Existing frame | Remains in place | Removed as part of the replacement |
| Installation scope | Generally less extensive | Usually more extensive |
| Installation cost | Generally lower | Usually higher |
| Glass area | May be slightly smaller | Determined by the new window and opening |
| Existing opening | Remains largely covered | Exposed for assessment |
| Changing size or configuration | Limited by the existing frame | More flexibility |
If the existing frame is in good condition and the current opening works for the replacement, an insert may be suitable. If the frame is deteriorated or the opening needs to be changed, a full-frame replacement may be more appropriate. The right choice depends on the condition of the existing window and the goals of the project.

Which Frame Material Suits Your Home?
Frame material affects the price, the upkeep and the look of the finished window. These are the main options Consumer Reports describes in its buying guide.
Vinyl frames are typically the least expensive. They usually come in white, and most can’t be painted or stained, so you’re choosing a color once. Hardware choices are more limited than with wood.
Wood frames tend to cost the most. Their exteriors are typically clad in aluminum or vinyl, which protects the wood from weather and reduces the need to repaint the exterior. Inside, they come in several wood species, such as pine, maple and oak.
Composite and fiberglass frames usually don’t need painting or staining. They’re built to look like a solid wood window while giving the frame a more stable structure underneath.
What Kind of Glass Should Replacement Windows Have?
Every window in Consumer Reports’ ratings is double-glazed and filled with argon gas, which makes a useful benchmark when you compare quotes. Low-E coatings add efficiency by reflecting heat.
Triple-glazed windows reduce noise and improve energy savings. According to Consumer Reports, that extra energy saving doesn’t justify the cost except in extremely cold climates or loud environments. If a quote includes triple-pane glass, ask what it adds to the price before you decide.
What Affects the Cost of Window Replacement?
Several of the choices above change the price. Insert replacement generally costs less to install than full-frame. Vinyl frames are typically the least expensive material, and wood tends to cost the most. Triple-pane glass can also affect the price, so ask the installer what the upgrade adds to the quote.
Ask each company to price the windows, the installation and any add-ons separately. This gives you a clearer way to compare the scope and costs shown on each quote.

How to Choose a Window Replacement Company
Even the best windows won’t deliver the expected look or comfort if they’re installed incorrectly. That’s especially true in older homes, where frames may have shifted over the years.
When you collect quotes, make sure each one spells out:
- The window brand and model
- How many windows, plus their sizes and types
- Any add-on features
- The installation details, with costs broken out
Ask, too, what the warranty covers, how long it lasts, and who handles a claim if something goes wrong with the window or the installation.
If your home was built before 1978, ask whether the project falls under the EPA’s lead-safe Renovation, Repair and Painting (RRP) rule. According to the EPA, “Federal law requires all renovation, repair, and painting firms (including sole proprietorships) working in housing… built before 1978, to be certified.” The agency also states: “All individuals performing activities that disturb painted surfaces on behalf of the firm are either certified renovators or have been trained by a certified renovator.” In addition, “A certified renovator is assigned to each renovation and performs all of the certified renovator responsibilities.” The EPA lists window replacement as covered regardless of square footage. Ask the contractor whether the firm is RRP-certified and whether a certified renovator will be assigned to the covered work.
Ask the contractor, as well, whether your project requires a building permit in your municipality and who will be responsible for obtaining it.

What Should You Do Before Getting a Window Replacement Quote?
Before you request quotes, list the windows you want replaced and note any problems you want the installer to assess. Bring that list to the consultation so the installer can assess which replacement method is appropriate for each opening. Then check that every quote you receive covers the items listed in the previous section.
