Windows & Doors Installation in Tacoma, WA
Windows and doors are among the most important components of any home or building—not just for appearance, but for energy efficiency, security, and daily comfort. At Mega General Construction, we provide professional windows and doors installation services throughout Tacoma, WA. Whether you're replacing outdated frames, upgrading to energy-efficient products, or finishing out a new construction build, our team ensures your openings are sealed, aligned, and built to last.
We work across a variety of architectural styles and property types, from classic craftsman homes in Tacoma’s North End to newer builds and tenant improvements throughout the South Sound.
Window Installation for Replacement and New Construction
Window installation requires more than placing glass in a frame. Every install must address water management, insulation, and style continuity. We offer full-service window installation for remodels, new construction projects, and light commercial buildings.
Retrofit and Full-Frame Window Replacement
When replacing older windows, we assess whether a retrofit insert will suffice or if a full-frame replacement is needed. Full-frame installs are more common in older Tacoma homes with worn sills, poor insulation, or water intrusion behind trim.
Energy-Efficient Window Upgrades
Modern window units feature double- or triple-pane glass, low-E coatings, and insulated frames. These products significantly reduce heat transfer, lower energy bills, and help meet Washington State Energy Code requirements.
Custom Sizes and Historic Replication
For homes with non-standard window openings, we install custom-sized units that match the original shape and trim style. In historic Tacoma homes, we replicate the look of wood-framed windows using updated materials that maintain character while boosting performance.
Exterior and Interior Door Installation
Exterior doors need to resist Tacoma’s rain and wind, while interior doors must function smoothly and fit within finished walls. We install doors for all parts of the home, from main entries and garage side doors to closets and bathrooms.
Entry and Patio Doors
We install front doors, side entries, sliding glass doors, French doors, and other access points. Our process includes removing old frames, leveling sills, and sealing the threshold to protect against drafts and leaks.
Interior Door Installation
For room entries, closets, and bathrooms, we install both pre-hung and slab doors. We also adjust rough openings during remodels to accommodate larger or more accessible doorways where needed.
Fire-Rated and Code-Compliant Doors
In duplexes or between garages and interiors, fire-rated doors may be required. We ensure all required doors meet Tacoma building code and are properly labeled and installed with matching hardware.
Weatherproofing and Energy Compliance for Tacoma Homes
The Pacific Northwest climate demands more than average window and door installs. Moisture, wind, and seasonal temperature shifts all play a role in product selection and installation technique.
Flashing and Sealant Systems
All exterior windows and doors are installed with integrated flashing systems and waterproof barriers. These details are essential to prevent leaks and long-term water damage in Tacoma’s rainy environment.
Insulation and Air Sealing
Gaps around frames are filled with low-expansion foam and sealed to prevent air infiltration. We use energy-efficient caulking and backer rods around trim to support long-term performance and help meet energy code standards.
Code-Compliant Egress Windows
In basements and bedrooms, we install code-compliant egress windows to meet emergency exit requirements. This often includes enlarging openings, cutting into foundation walls, and adding window wells with drainage.
Matching Windows and Doors to Tacoma’s Architectural Styles
Each Tacoma neighborhood has its own identity. From traditional wood-frame homes in Proctor to suburban builds in University Place, we help homeowners choose windows and doors that enhance—not erase—the original style.
Craftsman and Mid-Century Homes
Older Tacoma homes often have wood or steel windows and original panel doors. We match the dimensions, sightlines, and casing style of these features while using durable, modern materials that require less maintenance.
Modern and Contemporary Homes
Newer homes often feature large picture windows, minimal frame lines, and clean finishes. We install products that support open sightlines and expansive views while keeping the interior thermally efficient.
