Weather Resistance

Rain rain go away. As homeowners in the Pacific Northwest, we all know this statement is simply a wish that will never be granted. The more weather resistant your windows are, the less likely you will have to worry about the constant rainfall and cold weather we endure through most of the year. Low-quality windows sacrifice strength for price and we understand more than anyone the problems a poorly built and installed window can bring. Wood windows, for example, tend to collect rainwater over an extended period of time and are more susceptible to mold and mildew, leading to potentially exposing your family to health hazards. A high-quality window built with a strong focus on weather resistance will prevent moisture build-up and save you money and energy in the future, all while protecting your family from unpredictable weather conditions.

High-quality windows will provide strong security and significantly reduce the noise on the exterior of your home. Secure locking systems will provide your family protection from burglars who seek to enter your home through forcible means. At the same time, helping reduce noise from the world outside so that you and your family can enjoy a more peaceful environment while in the comforts of your own home.

Increased Home Value

The curb appeal of your home will increase based on how well your windows compliment the rest of your home. As homeowners, we all want windows that are both cosmetically appealing and durable but who says we need to sacrifice one for the other? Carefully selecting your windows will allow you to have complete creative control of the outcome and at the same time, provide you with a window selection known to stand the test of time.

Energy Efficiency

It’s no surprise that all windows are inherently made to be energy efficient. The major difference is the effectiveness of the windows you choose to install and who you choose to install them for you. These two very important aspects of your windows will either save you money over a long period of time or force you to waste money that could otherwise be used to upgrade the other parts of your home. Whether you want to keep the cool air inside during the summertime or prevent the cold air from entering your home during the winter months, the type of windows you install will play a large role in just how comfortable you hope to be.


Do you need help deciding if your windows need to be replaced? We always recommend calling a window professional for a free in-home inspection, but, here are a few things to look for before deciding to get new windows for your home:

Energy Inefficiency

If your home is experiencing air leaks around your windows, it’s possible your windows were not installed properly or the time to replace your windows is drawing near. Air leaks increase your power bill because your windows aren’t doing a very good job of maintaining a constant temperature in your home. If you begin to notice an increase in your power bill, it’s always good to consider that your windows may be playing a role in higher heating/cooling costs. It never hurts to call your contractor for an inspection.

Home Security

Windows are one of the main entry points to your home so windows that are deteriorating due to old age tend to become less secure over time. Over time, your windows may eventually fail to lock which can pose a huge security risk and make forced entry much easier for people who try to enter your home. Burglars often look for vulnerable windows that look worn and outdated so it’s important to always be sure to have windows that are still secure.

Water Damage

If your window is leaking it’s important to find out the cause immediately. If left unchecked for too long, it can rot your windows depending on what materials your windows are made from. Whether you need a new window or not will depend on the extent of the damage and how long your window has been exposed to the water pooling around your windows.

Cracks in Window Frames

Cracks in your window frame can progressively damage your windows over time if left untreated. If you decide to wait too long to get the cracks fixed, air, water, and even insects can enter your home and help weaken the integrity of your windows. Weather-resistant Vinyl windows are built to protect and preserve your windows in a region with wet weather conditions such as the Pacific Northwest.

Old Windows

The average lifespan of residential windows is anywhere between 15-20 years if your windows are installed securely of course. As a homeowner, knowing exactly when each window was installed can help you determine if you may need new windows sooner or later. The best thing you can do is to replace your windows before they become a problem.

If you have any of the problems listed or just questions, give us a quick call and our trained professionals will answer any question you may have about your home windows. Better safe than sorry we always say.

The first step we take when removing your windows is to evaluate and take measurements to determine the size of your current windows and ensure your new windows are prepped to replace your old windows. This initial process is very important because without establishing the proper measurements, your new windows may not align properly which can cause a poorly sealed installation.


The next thing we do is remove the sash from your windows in order to make the process smooth and easy.


Once sashes are removed, the next thing we do is expose the nailing fin by removing any siding and window trim with a saw. The nailing fin is a thin piece of metal that extends all the way around the window itself. It usually comes with predrilled holes in it to allow contractors a way to easily either nail or screw in the nailing fin to your home. For those who are more curious, the nailing fin is great for keeping water and moisture out of your home. A must-have if you want high-quality windows to protect your home.


Now that the nailing fin is exposed, our contractors will unscrew any screws or remove any nails that are keeping the window attached to the side of your home. Once the window is loose, our team will carefully remove and dispose of the window.


After the window is carefully removed, any excess materials including siding, nails, screws or any other type of debris are removed and cleaned out. More measurements are taken to prepare for the new window that is going to be installed. Once everything is leveled out and planned accordingly, our new window installation process will finally begin.


Our team of trusted contractors will then proceed to place the window based on the measurements take and begin screwing the nailing fin into the side of the home.


Vycor is then placed around the interior and exterior perimeter of the window over the flange (nailing fin). Vycor is an industry-leading weatherproof solution used to help better protect your home from the wet weather conditions in the Pacific Northwest.


The appropriate measurements are then taken again to prepare for the trim. We then cut and place the trim around the windows (on top of the Vycor) and add a head flashing piece that will prevent water from leaking in at the joint between the bottom edge of the siding and the top of the head trim. The trim is then fastened with corrosion-resistant nails, a conventional corrosion-resistant construction screw, or a hidden fastener system.


A sealant is then added to the window frame and trim. Small adjustments are made if necessary. Our team will then clean up the worksite before doing any final inspections.


Our home window installation experts will take the time to check every aspect of your newly installed windows upon completion and double-check the area for any debris to ensure we leave the exterior of your home looking better than when we arrived on site.


How Long Will My New Windows Last?

A new window may last you as little as a couple of months or for many years to come. As you can probably guess, the main reason why is due to the quality of the windows and how well they are installed. The windows we install are built to last, plain and simple. Great vinyl windows have held strong for homeowners for 30+ years when they are properly maintained. Cheap, low quality windows can often become more expensive because you will be forced to replace them more frequently, sometimes paying many times over your lifetime.

Can I Replace My Wooden Window Frames?

If your old wooden window frames are rotting away, we can easily replace them with new vinyl windows. Our team of window specialists are trained to replace just about any kind of window you can think of, including any windows that may have caused damage to your home.

What Are My Top Reasons To Replace Windows?

The 4 top reasons are as follows:

  • Save money on your home energy bills.
  • Increase curbside appeal to your home.
  • Rotting Windows
  • Windows are beginning to become worn out and the integrity begins to lose strength.

What Is An Energy Star Certification?

The Energy Star Certification is a process of testing and verifying the energy efficiency of home products which include the energy efficiency and durability of windows. The higher-performing windows are then given the energy star label which is backed and certified by the U.S. government. Energy Star windows generally have a strong layer built to protect you and your furniture from UV rays.

How Long Will It Take To Install A New Window?

Once your old window is removed, it usually takes only a few hours to install the new window and clean up any debris from the removal process. It varies based on the size of the window being replaced and how much damage to your home from the previous window we need to repair.

Do You Subcontract Your Work?

No! We do all of our work in-house and our trusted professionals at Evergreen Home Exteriors will take extra care of your home window installation.


  • I think this is the same company but they show the name Evergreen Home Exteriors LLC. Jesse and Shawn did the work. They were prompt, well prepared, courteous, and worked through cold rainy weather. They corrected level of the under frame of our deck, replaced stringers that were degraded, installed Azek PVC with hidden fasteners and black aluminum rails with cable. They are obviously experienced and their truck was well stocked with all necessary tools. All of the scrap was hauled away. This was done in two and a half days. Would hire them again.

  • I'm so happy !! We met with them first and talked over everything I needed to get done to make sure we had the right fit for our deck project.They sent out two brothers to do the work and I need to tell you they were so meticulous in everything they did for us. Quality work and they cleaned everything up as well. Polite , Professional and knowledgeable. I'd recommend them to everyone. I'm thinking about hiring them on again to do more work in the future!

  • These guys would get more stars if allowed. They went above and beyond, especially Paul. I can’t thank them enough.

    Margie N. in auburn, WA
  • This crew is fantastic! Our project had several complexities as we were building on a slope. Every step of the process - from the site survey and consultation, to construction and clean up - was completed with professionalism, intelligence and a commitment to quality. Our deck is gorgeous! I'll definitely recommend Evergreen to anyone and everyone.

  • This company built a porch deck for me. They exceeded my expectations at every turn. The estimator arrived on time. He was knowledgeable and so helpful. The project started on time and finished on time. I was out of state during the build and my friend was checking on the progress for me. They were consistently polite and informative to my friend but they also called and gave me a progress report every day! I had previously owned a construction company in Denver and am VERY picky and they exceeded my expectations!

    Nicole P. in Lakewood, WA
  • Evergreen Windows replace/restored the underside of a deck with stamped concrete on the surface. Very complicated project and I had bids costing $10,000 all the way up to $54,000. Thankfully we went with Evergreen Windows, LLC. Excellent Bid, Started on time, Finished ahead of schedule, Adjusted cost accordingly, Excellent carpenters, and Excellent communication!! I highly recommend Evergreen Windows, LLC, and I would use their services again for future projects.
