Oversized Window Installation in Colorado
Originally published on March 4, 2017 • Updated on November 1, 2025
Sometimes, homeowners want bigger views — and that means bigger windows. When it’s time to lift something massive, Gravina’s Window Center of Littleton® brings in the “enforcer”:
CRL Wood’s Ladder Lifter.
This specialized tool helps our expert installers move and set oversized Infinity® by Marvin® windows safely and precisely. Whether it’s a full window wall or a large picture window, we use the right equipment, the right crew, and the right technique for the job.
The project below shows a massive window wall installation in Ken Caryl Valley, where we combined expert planning, scaffolding setup, and safety-first precision to complete the replacement flawlessly. That’s what 50+ years of Colorado window experience looks like — done right, the first time.
Built for Colorado’s Views and Weather
Big windows mean big rewards — more light, more views, and more wow factor. But they also require the right materials and experience. Infinity® by Marvin® fiberglass frames are engineered to handle Colorado’s temperature swings without warping, cracking, or losing energy efficiency. That’s why we trust them for large-format window installations.
Prepping the Windows
Before any oversized window install, our team starts with a detailed game plan.
Retrofitting large windows into an existing structure can be tricky — every angle,
frame, and measurement has to be precise. We inspect the opening, confirm load-bearing
support, and map out how to safely maneuver each piece into place.
This prep work is what separates an average job from a flawless one.
From scaffolding setup to material staging, everything is done with safety
and efficiency in mind — ensuring your new Infinity by Marvin
windows fit perfectly and perform beautifully for decades.
This Replacement Window Weighs Around 400 lbs!
Installing oversized windows isn’t for the faint of heart.
Jon Gravina and our installation team are pictured here lifting a massive Infinity by Marvin fiberglass window — a 2-wide awning picture unit that weighs nearly 400 pounds of glass and fiberglass combined.
Projects like this demand teamwork, precision, and muscle memory built from years of experience. Every member of the crew knows their role, from guiding the lift to ensuring perfect placement once the unit reaches the frame. Safety harnesses, scaffolding, and clear communication make heavy installs like this not just possible — but routine for our Colorado installation experts.
This is what sets Gravina’s Window Center of Littleton® apart: we don’t shy away from challenging installs. We plan them, prepare for them, and execute them with confidence. Because when a window weighs 400 pounds, you need more than strength — you need a team that knows exactly what they’re doing.
Precision and Teamwork for Heavy Window Installation
Think again. It took five of our professional installers to carry this Infinity® by Marvin® fiberglass window into place — and that’s with the help of years of teamwork, balance, and precision. Every hand matters when maneuvering a 400-pound unit safely across uneven ground and into a waiting frame.
This photo, taken during a recent project in beautiful Ken Caryl Valley, captures what our installation days often look like: careful coordination, expert communication, and a shared respect for craftsmanship. Every detail counts — from how we lift, to how we level, to how we secure each window for lasting performance.
At Gravina’s Window Center of Littleton®, this isn’t just hard labor — it’s skilled work backed by decades of experience. Oversized window installations are a team sport, and our crew shows up ready to deliver precision with pride.
