CalCo Design & Renovation is proud to offer Marvin windows to homeowners throughout Lancaster County and the surrounding areas. Known for exceptional craftsmanship, premium materials, architectural flexibility, and long term performance, Marvin gives homeowners the ability to choose windows that truly complement their home instead of settling for a one size fits all replacement.
Whether you are replacing aging windows throughout your home, renovating a historic property, building an addition, or completely redesigning your exterior, CalCo can help you find the right Marvin collection, style, material, and finish for your project.
There is a reason Marvin is considered one of the premier names in windows and doors.
Marvin offers a level of design flexibility that goes well beyond a typical replacement window. Depending on the collection you choose, you can customize materials, interior finishes, exterior colors, hardware, glass, divided lites, window configurations, and architectural details.
For homeowners investing in a high end renovation or looking for windows that become part of the architecture of the home, Marvin offers possibilities that traditional replacement windows simply cannot match.
Marvin uses materials including natural wood, extruded aluminum, High Density Fiberglass, and its proprietary Ultrex® fiberglass across its different collections.
From traditional double hung windows to dramatic expanses of glass and contemporary window walls, Marvin offers solutions for an enormous range of architectural styles.
Marvin offers energy efficient glass options designed to help manage heat transfer, solar heat gain, UV exposure, and overall home comfort.
Premium materials and carefully engineered components help Marvin windows withstand changing temperatures and years of exposure to the elements.
Replacing windows gives you an opportunity to do much more than replace what is already there.
Changing window colors, grille patterns, configurations, trim, and even window sizes can completely change the character of a home.
CalCo can help you coordinate your Marvin windows with:
Instead of looking at each improvement individually, we can help you create an exterior where every element works together.
Beautiful windows should also contribute to a comfortable home.
Marvin offers energy efficient glass configurations and Low E coatings designed to help control the movement of heat through your windows.
Low E glass can help reduce solar heat gain during warmer weather and reduce heat loss during colder weather. It can also reduce exposure to UV rays that contribute to fading of flooring, furniture, rugs, and other interior finishes.
Available glass packages vary by collection and window configuration, allowing CalCo to help you choose options appropriate for your home and project.
If your windows are reaching the end of their useful life, they may not be the only part of your exterior that needs attention.
Siding, roofing, doors, trim, soffit, fascia, and windows all work together to protect your home.
Completing multiple exterior improvements together can also make it easier to coordinate colors, trim, flashing, and other details that affect the finished appearance.

Paul and Drew are amazing! I absolutely LOVE my new shower!!!! Not only did they do the normal stuff you would expect from a contractor like show up when they said they would, clean up before they left everyday, and complete the job in the time they said they would. But they are artist! They took my vision and brought it to life!
