Pella- How to install vinyl replacement window Pella 150

What's up guys/gals, in this video I am replacing old wood windows with new vinyl replacement windows. I am specifically using Pella series 150 replacement windows for this project.
Honestly, replacing old wood windows with new vinyl replacement windows is very simple as long as you follow some simple steps. The most important part about this project is to ensure the replacement window is level and proper flashing and insulation is in place to protect from water intrusion.
First, measure the opening for the replacement window. I show you how to measure for your replacement window in this video. Next, remove the old window and clean the opening. Always dry fit the replacement window before applying flashing and silicon. You will find most of the time you will need to remove the casing trim from one or two sides of the window frame in order to make room for shims...etc.
Once you are happy with the dry fit, proceed with applying flashing tape and silicone caulking. Place the replacement window in the opening, pre-drill before screwing in the window and finish with foam insulation to fill any gaps between the vinyl replacement window and the framing.
The Pella series 150 replacement window is a good choice to upgrade from wood windows to vinyl replacement windows at an affordable price.

I am doing my first pella 150 replacement window in my house. Their online directions are bad. Your video has been a tremendous help, very well done and a huge help to me thanks so much matty

[ryanfrancis]

I was on the fence about replacing my windows myself but after watching this video I am very confident that I will replace my windows myself. Thank you, this video is exactly what I needed. You hit all the details that is required to replace a window.

[KennyOlson]

This pocket replacement is almost exactly what I'm dealing with. You're giving a new homeowner confidence to do this myself and save a ton of money. Cheers!

April 24, 2023 Im replacing two windows today and you built a great confidence in me to do it myself thank you so much!!!

[JoeGriffith-cpio]

No wonder you have so many views. I was pretty confident in the first place. You made me realize many of the labor-intensive procedures I was going to do aren't necessary. I am going to have much repair to do. I live in an old country schoolhouse built in 1917. It had extra classrooms and plumbing in the early 50s. then was converted to a home in the early 60s, that's when these windows were installed. Anyway, I'm rambling, what I wanted to say is brother you ROCK!!! I'm sure I'll watch a few more times. I have 14 windows to install and massive amounts of rot to repair so the time you saved me is much appreciated.

[davidreyna]

Very good instructions. I do construction, but have never replaced windows. Thank you for this video. Am more confident doing it myself and saving tons of $.

[jackbolt]

Hey brother, I'm going to be replacing some windows and after watching your videos, I feel confidant I can do it. Thank you for your expertise!

[robertpowell]

Thank you. I am slow so need to watch it multiple times. Thank you for the useful detail. Very important.

[briant]

This is one of the best videos for replacing windows. With my limits skills i think i can do it. Pella should make you there window replacement spokesman

[DaGratest]

Thank you. Perfect description of window flashing on a replacement window. Just failed an inspection because of this but every video I've seen was all new construction.

[steven]

Thank you for this video! It was the only video where the opening wasn’t level and plus, and how you fixed it!
I just had four pella 250 installed my lowes and they did an awful job! No flashing, no silicone, no insulation (and it needed it-they just used latex to fill in), left the skirts falling off on the front and no shimming. Very disappointed and will take them out and do it myself.
The only reason I wanted to pay someone was because I wanted to have the exterior tripped aluminum wrapped (or capped). I did find a website that has pre shaped aluminum for windows and doors and I would be able to do it myself.
Thank you again for this very helpful video!

THANK YOU! 🥹 Best video I could find, taking the 2 seconds to show a close up of something really makes the difference for those watching. Awesome

[davidforrest]

Thanks. From the pella instructions I didn't see how to remove the upper side filler bits to access the upper pre-drilled holes and had 4 leftover screws. Your video was a great help in figuring out where they belong.

Thank you for the information. That's the replacement window I decided to buy, as they are on the shelf at Lowe's home improvement store. The part that answered my question was that the window came with a piece of trim that connects the bottom of the window to the slope of the sill. I thought I would have to make a wage molding or whatever to accommodate the space under the replacement window. Very informative video. Thanks, I now feel more confident buying six of those windows and doing the installation myself.

Excellent tutorial, but you need to (1) caulk the outside where the existing blind stop meets the replacement window frame and (2) cut a 1/4” weep hole in each end of the sill adapter (skirt), 1” from each end. I also prefer to caulk the sill adapter to the existing sill to minimize wind, bug, and rain intrusion. You’ve got a back dam of caulk between the frame and the stool, but keeping stuff out is generally better than relying entirely on caulk near the interior.

Also, the sill adapter won’t always be a perfect fit in either height or width. It has two score lines on the back to trim it to height, and I find that a large pair of end nippers is perfect for cutting the ends to length. Installing it from the outside after trimming to fit is a little more difficult, but a rubber mallet or dead blow hammer and a plastic tapping block works wonders.

After seeing your video I feel like I can do this- great instructional video

[spintius]

This is by far the best instruction video in installing replacement windows.

Wish you showed the measurement a little closer to the measuring tape. Nevertheless, thanks for the great video!

[peaceall]

I’m inspired! I just got a quote of $17k to replace my windows with Pella 150 series, half of that was labor. I’m going to go buy one window, try and do it myself (I’m modestly handy), and if it works out, I’ll keep going. If not, I’m keeping my 37 years old windows and repainting the frames. Thanks!

[ScottyLo]

Very helpful video. Doesn’t look too bad. I’d treat each window as a little project and 27 windows later I’d have it down.
