Replacement Window Installation Process

The replacement window installation process -  Replacement windows installation in Utah by Advanced Window Products

 

Whether you’re a new homeowner or have lived in your house a lifetime, you’ll need new windows at some point. Maybe you’ve been putting it off because it feels like an expense or hassle. If you could use new windows in your home, Advanced Window Products are the replacement window installers who will make it a positive experience.

Steps for Window Replacement Installation

The whole process can seem intimidating, but it doesn’t need to be. As with any home maintenance or upgrades, careful planning, and good decision-making should ensure a straightforward installation experience. Be sure to first define your goals and budget for the new windows. Consider any neighborhood rules such as historic district requirements. How much time do you have in your schedule for the work to be done? Is the schedule realistic and is extra time built-in? Answering these questions first will help narrow down your best options, especially when consulting with a window expert.

Once all of these factors have been taken into consideration, here are the steps for window replacement installation.

Ensure a Proper Fit

Measure for Replacement

Our window installation professionals measure the opening where the new windows will go to make sure that they’re the right size. This can include measuring the height and width of the existing window frames to determine an accurate size for your new windows.

Take Out Current Windows

The exact way to remove current windows for a window replacement depends on certain factors, which our experts take into consideration. For example, some windows might have screws in place that need to be taken out. Others might have sash springs or weights that will need to be taken out. Windows with stops need to have interior or exterior stops removed depending on where the installation is taking place. Outdoor installation requires removing exterior stops, while indoor installation requires removing interior stops. If there is any wood damage, our professionals will repair it before installing your new windows.

Clean the Area and Apply Flashing

Our team will clean the area before putting your new windows in, such as removing any debris left behind from scraping paint along edges in order to remove the current windows. We then apply flashing tape to the entire sill area.

Level the Sill

The sill needs to be level in order for new windows to open and close properly. If the sill is not level, our experts use shims to correct this. These shims are typically held in place firmly with flashing tape and screws.

Caulk the Frame

Our professionals apply caulk along the top of the window frame and along the window sill and stops. This helps ensure that there are no gaps or openings around your new windows. We usually place the new windows in the frame first to get a better idea of where spaces or gaps might occur.

Put the New Window in Place

Our team sets the new window in the frame and ensures that it rests firmly in place. We use shims, which should go inside screw holes in the frame, to hold the window in place. These shims are then secured in the frame with screws.

Check for a Proper Fit

Our window replacement professionals make sure that the new window sashes are even within the frame. If the sashes are uneven, we can place shims at the meeting rails. Once the sashes are even, our experts open and close the window to make sure it works properly by opening and closing smoothly. New windows should not get stuck or slide up and down too easily or quickly.

Insulate New Windows

New windows might have exterior gaps that need to be filled in. This can be done using spray foam insulation, which helps prevent drafts from occurring and keeps indoor heat from escaping.

Install the Sill Adapter and Trim

Our professionals cut the sill adapter to the right width, then drill holes in the bottom of it, so that it can be held in place. We typically use finish nails for installing the exterior trim, which runs along the edges of the window frame. The edges are then sealed using caulk. Our experts use caulk on the edges of the interior trim as well to seal up any openings or gaps.

This entire process is critical because the most advanced windows won’t help your house unless they are properly seated and fully sealed from outside air and moisture. This can take a few hours per window.

When Should I Replace my Windows?

Maybe your house is newer and you believe windows are not an issue. Unfortunately, because of the builder profit motive, those new windows might not insulate your rooms as well as they should. If your home is newer ask:

  • What is the U-value of the windows? Is it less than the Energy Star rating for your area?
  • Is there a noticeable sensation of outdoor cold or heat near the window?
  • Do the windows feel or look like they are low quality?

If you answered yes to any of these questions, it may be time to install windows. An energy audit can help estimate your potential energy savings.The sooner you have high-quality windows installed, the sooner they start paying you back.

On the other hand, if you’ve lived in your home awhile, you might not notice window problems that have developed gradually. Years of weather and wear will reduce the integrity of the windows. Also, older windows can’t give you the high level of comfort and efficiency of modern units.

  • Do you notice drafts or noise coming from the windows?
  • Do the wood or vinyl appear worn, dry or cracked?
  • Are the windows single pane or do they lack film?
  • Are they difficult to operate or just look worn out?

Answering yes to any of these could mean you haven’t even noticed how drafty, noisy or uncomfortable your windows have become.

Frequently Asked Questions About Replacement Window Installation


Advanced Window Products installs flashing around your window to keep water and moisture out of the gaps around the frame. This process has two parts. First, an experienced technician preps the rough opening. Second, the window is secured and squared. We ensure that the flashing is integrated with the house wrapping and sealed with construction tape and silicone caulking to keep your home secure and dry.


A pocket window is also called an insert window. They are inserted within an existing opening. Advanced Window Products recommends pocket window installations when you want to upgrade to one of our high-performing models. Preserving the existing frame, casing and trim saves time and money. In order to use this method, you need a window frame that’s square, level and in good condition. It’s also recommended for historic homes where you wish to preserve the character of the existing structure. During the process, our training installers leave the exterior stops and sashes in place and the new window is installed from the exterior of the home.


Retrofit windows match the frame of an existing window. In this case, we remove the glass of the existing window and fit the new window with any necessary adjustments. The siding, walls and window frame are untouched and this is the least invasive window installation. On the interior, you may see a small gap between the old and new window frames. Advanced Window Products may use expanding foam and insulation to seal the gap. All windows purchased from us come with a double lifetime warranty.


For standard, double-hung, vinyl and double-pane windows, the typical window plus installation cost is between $450 and $600. Wood windows are more expensive and cost between $800-$1,000.

My wife and I were very satisfied with Advanced Window Products. Replacing eight 60-year-old single-pane aluminum windows was a smooth process, from the accurate descriptions and color selection to the precise measurements.As promised, the windows were ready two months after we placed our order. The installers were very careful when removing the old windows from the brick walls and installing the new custom double-pane windows. They completed the entire project in just five hours, and the windows look great. - 6/11/2026

I recently had all my windows replaced and had a great experience with Advanced. That sales process was quick and respectful without having to sit through a long drawn out sales pitch. They were efficient with their time at our home and they will dows are great. We have noisy neighbors and with the new windows we dont hear their late night music which is such an added bonus. Our home temperature also has stayed consistent with a decent reduction in our cooling costs. - 6/10/2026

We recently installed 13 new Advanced Windows and have already noticed a difference in the heat efficiency of the windows. The installation team was right on time and finished in less than a day! We have received many compliments on the looks of the windows. They were easy to work with through the whole process of purchase, communicating timelines, scheduling and installation. The windows are a great product and at a good price. I recommend working this Utah company. - 6/08/2026

Crystal Nielson-Barney went out of her way to help us. They made beautiful windows in time for us to sell our house, and when we accidentally broke a pane in the new window, Crystal made sure we had the replacement in just over a week so that we could close on selling our house. We highly recommend Advanced Windows and their professional team. - 6/05/2026
