Seattle & Eastside Entry Door Specialists

Your entry door does more than define curb appeal — it protects your home from moisture intrusion, air leakage, and security risks. In the Pacific Northwest, where prolonged rain and seasonal weather shifts are common, proper entry door installation is critical to long-term exterior performance.

Synapse Construction provides professional entry door replacement and installation services throughout Seattle and the Eastside. We focus on both aesthetics and building-envelope integrity to ensure your new door enhances your home’s appearance while protecting it from the elements.

When to Replace Your Entry Door

Many homeowners consider door replacement for visual reasons, but performance issues are just as important. You may benefit from a new entry door if you notice:

Drafts or air leakage around the door
Water intrusion during heavy rain
Soft or deteriorating wood trim
Difficulty opening, closing, or locking
Visible rot or moisture damage
An outdated style that no longer complements your home

Addressing these issues early can help prevent more extensive exterior repairs.

Our Entry Door Installation Approach

We take a detail-oriented approach to entry door replacement to ensure proper integration with your exterior systems.

1. Evaluation of Existing Conditions

We assess the condition of the existing door, surrounding trim, flashing, and exterior transitions.

2. Careful Removal

Existing doors and compromised materials are removed without damaging adjacent siding or trim.

3. Proper Weatherproofing & Flashing

We install appropriate flashing and sealing details to help prevent water intrusion at the door-to-wall connection.

4. Professional Installation

New entry doors are installed with precision to ensure smooth operation, secure locking, and long-term performance.

5. Finish Integration

Trim, sealing, and exterior transitions are completed cleanly for a cohesive appearance.

Custom Entry Door Options

We offer a wide range of entry door materials and styles to suit your home and performance needs, including:

Fiberglass entry doors
Wood entry doors
Steel entry doors
Modern and contemporary styles
Traditional and craftsman designs

Doors can be customized with hardware finishes, glass inserts, sidelites, and color options to complement your home’s exterior.

Entry Doors & Exterior Performance

Entry doors are a key transition point within your home’s exterior envelope. Improper installation or aging materials can contribute to:

Moisture intrusion around trim
Exterior rot development
Air leakage and energy inefficiency
Paint and finish failure

Our installation approach considers how the door integrates with siding, trim, and exterior sealing systems to support long-term durability.

Entry Door Replacement as Part of Preventative Exterior Care

Entry door replacement often pairs with other preventative exterior services, including:

Coordinating improvements helps protect the full exterior system.

Considering a Larger Exterior Upgrade?

Entry door replacement can also complement broader exterior projects such as siding & window replacement, deck upgrades, or seasonal exterior improvements.

If you’re unsure whether your door requires replacement or repair, our team can assess the condition and recommend the most appropriate next step.
