Built To Keep The Weather Out. Installed To Last.
Doors, Windows, and Sliding Doors
Protect Your Home For Years To Come
Most window and door problems aren’t caused by the products themselves. They’re caused by improper installation that allows water and air to get behind the exterior envelope. At Built To Last Construction, Inc., every replacement is installed with careful attention to flashing, waterproofing, air sealing, and long-term performance so your investment protects your home for years to come.
Whether you’re replacing a single entry door or updating every window in your home, we treat each opening as part of the structure, not just a finish item. Our goal is a clean installation that looks right, performs as intended, and helps prevent moisture intrusion before it becomes a much larger repair.
What is included
- Existing door or window removal
- Flashing, waterproofing, and air sealing
- Window, door, and patio door installation
- Exterior trim, caulking, and weather sealing

We’ve installed doors and windows for homeowners in Santa Monica, Malibu, Pacific Palisades, and Brentwood, delivering weather-resistant installations designed to protect homes along the Westside.
How We Work
A Careful Installation From Assessment To Final Inspection.
01
Evaluate The Opening
Every project begins by inspecting the existing opening for water intrusion, flashing failures, structural damage, and any conditions that could affect the new installation.
02
Prepare The Opening
The existing unit is removed carefully, damaged materials are repaired if needed, and new flashing, waterproofing, and air sealing are completed before installation begins.
03
Install And Weatherproof
Your new window or door is installed to manufacturer specifications and integrated with the home’s exterior envelope for long-term weather protection.
04
Inspect And Final Walkthrough
Interior and exterior finishes are completed, the installation is tested, and every detail is reviewed before the project is considered complete.

Why BTL for Windows and Doors
A Quality Window Or Door Is Only As Good As The Installation.
Even the best window or door can fail if it isn’t installed correctly. At BTL Construction, we look beyond the product itself and focus on how it integrates with your home’s exterior. Proper flashing, waterproofing, air sealing, and finish work all play a role in protecting your investment and preventing future problems.
The Opening Comes First
Before any new unit is installed, we inspect the existing opening for water damage, structural concerns, and signs of previous installation failures. Correcting those issues first helps ensure the new installation performs the way it should.
If hidden rot, deteriorated framing, or failed waterproofing is discovered, we address those conditions before moving forward. A quality installation starts with a sound opening, not simply a new product.
Built To Keep Water Out
Every installation includes proper flashing, waterproofing, air sealing, and weather protection designed to help keep moisture where it belongs. We don’t believe in taking shortcuts that will end up creating expensive repairs later on.
Our installation methods are intended to protect the surrounding structure just as much as the new window or door itself, helping reduce the risk of future leaks and water intrusion.
Designed For Coastal Homes
Many Westside homes face constant exposure to salt air, sun, and changing weather conditions. We recommend materials and installation methods that are appropriate for the environment so your windows and doors continue performing for years.
Choosing products that fit the environment can improve durability, reduce maintenance, and help your investment last longer in coastal conditions.
Finished With Attention To Detail
From interior trim to exterior caulking and final adjustments, every detail is completed before the project is considered finished. Our goal is an installation that looks clean, operates smoothly, and performs exactly as intended.
Before completion, we review operation, inspect weather sealing, and make sure every finish detail meets the same standards as the installation itself.
What to Expect
A Proper Installation Protects More Than Your Window Or Door.
Every BTL window and door replacement begins with evaluating the existing opening, not simply measuring for a new unit. We inspect the framing, flashing, waterproofing, and surrounding structure to identify conditions that could lead to future leaks or premature failure. If we uncover hidden moisture damage, we can also complete the necessary water damage repairs before the new unit is installed, ensuring the problem is fixed at its source.
Once the opening is ready, we remove the existing unit, complete any required repairs, and install new flashing, waterproofing, and air sealing before the replacement window or door goes in. Every component is installed according to manufacturer specifications while also integrating with your home’s exterior envelope for long-term weather protection.
Whether you’re replacing a single front door or updating every window during a larger renovation, our installation process remains the same. Many homeowners include new windows and doors as part of a home addition or ADU or a broader remodeling project, allowing finishes, trim, and exterior details to blend seamlessly across the entire home.
Before we consider the project complete, we verify operation, inspect the finished installation, complete all interior and exterior trim work, and perform a final walkthrough with you. The goal is a finished product that looks great, performs reliably, and helps protect your home from the elements for years to come.
Common Questions
Answers before you ask.
If your question is not here, we are happy to talk it through on a call.
Do I Need To Replace All Of My Windows At Once?
Not always. If only a few windows or doors have failed, we can often replace them individually. We’ll evaluate the condition of your existing units and explain whether a phased approach or a full replacement makes the most sense.
If you’re planning a future renovation or addition, we’ll also help you determine whether it makes sense to complete the work all at once or over time. Our recommendations are based on your home, your goals, and your budget.
Can You Match My Existing Trim And Finishes?
Yes. We take the time and care to match interior trim, exterior casing, and surrounding finishes so the new installation looks like it belongs with the rest of your home. Our goal is a finished result that blends in, not one that stands out.
When an exact material or profile is no longer available, we’ll recommend the closest option and explain the differences. We’ll always discuss those choices with you before work begins.
Will New Windows And Doors Improve Energy Efficiency?
In many cases, yes. Modern windows and doors can help reduce drafts, improve comfort, and increase energy efficiency when they’re installed correctly. Proper installation is just as important as choosing a quality product.
We’ll help you understand the available options and explain how different products may perform in your home. The right combination of products and installation can make a noticeable difference in comfort throughout the year.
Do You Replace Windows And Doors Throughout The Westside?
Yes. We install windows and doors for homeowners throughout Venice, Playa Vista, Marina del Rey, West LA, and surrounding Westside communities. We’re familiar with the different styles and construction methods found throughout the area.
