Our Replacement Processes
At Lake Washington Windows and Doors, we have our installation process down to a science. When embarking on a project with new customers, we follow the same 5-step process every time.
Our Patented Leak Armor Guarantee Protects Every Window
Our exclusive Leak Armor installation was born from thousands of installations and years of experience. By utilizing layers of flashings, pans, and sealants, our advanced Lake Washington windows’ Leak Armor system provides commercial-grade benefits in your residential home at no extra cost. Coupled with our top-of-the-line window selection, this patented technology makes your windows near invincible. Benefits include:

- Increased resistance to water intrusion, critical for the rainy PNW climate
- Extra protection provided at the window sill protects against moisture, helping to prevent wood rot
- Decreases the air infiltration around the window, helping reduce drafts
- Improves sound control, keeping more outside noise out of the home
- Improve energy efficiency, saving you money on heating and cooling costs

Our Simple 5-Steps Replacement Process
Step 1: Complimentary In-Home Consultation
The first step in our replacement process is scheduling a convenient time for a window specialist to visit your home and complete a complimentary, no sales pressure consultation. During this time, we’ll inspect your home windows or doors, answer any questions, and ask a few of our own to find the best solution based on your needs. Then we’ll take a few rough measurements and get back to you with a quote as quickly as possible.
Step 2: Agreement
Once you decide to move forward, we’ll draft and send a written agreement created to protect your interests. We believe good paperwork makes good friends, so this agreement will give you every detail of the project we’re embarking on, our contractor’s license, and the total deposit payment we’ll need to get started.
Step 3: Critical Measurements
With the paperwork out of the way, we’ll schedule another convenient time for our lead installer to visit your home for an hour or less. During this time, they will complete the critical measurements needed to place your order with our manufacturers.
Step 4: Schedule Installation Date
Once ordered, your product will require 2-5 weeks to be manufactured, depending on the package selected. When we’ve received confirmation of your order’s arrival date, we’ll call you to schedule the final installation and then complete a courtesy call a few days before to reconfirm our appointment. We’ll need between 2-5 days to complete the installation, depending on the project size, and during that time, we promise never to leave your home unsecured.
Step 5: Installation
Finally, it’s time for us to install your new products. Throughout the process, we’ll complete most of the work from the exterior of your home. If we need to enter your home at any point, we’ll be sure to ask your permission first, lay down ground covering, and vacuum any debris as we go. Our installation teams are highly-trained and understand the importance of treating your home respectfully and leaving it clean at the end of each day. Finally, we’ll remove the old fixtures, dispose of them responsibly, collect the remaining balance, and leave you in peace to enjoy your newly upgraded home!
