Stop Heating the Neighborhood.

Did you know that up to 30% of your home's heat energy is lost through old or poorly sealed windows? If your windows are difficult to open, drafty, or have condensation between the glass panes, they are costing you money every single month.

At iRenovate Pro, we believe that a great window is only as good as its installation. Even the most expensive glass will fail if the frame isn't insulated and sealed correctly. We specialize in custom-fit replacement windows and doors that maximize energy efficiency without sacrificing style. Whether you have a historic home in Frederick or a modern build in Northern Virginia, we have options that fit your architecture and your budget.

The iRenovate Pro Difference:

Precision Fit

We measure down to the 1/8th of an inch to ensure a tight seal against air infiltration.

Insulated Frames

We don't just pop the window in; we insulate the voids around the frame to prevent drafts.

Security Focused

Our entry and patio doors feature reinforced strike plates and multi-point locking systems for your peace of mind.

Your front door is the focal point of your home. We install high-durability Fiberglass and Steel entry doors that resist denting, warping, and rotting. Available in realistic wood grain textures or smooth modern finishes, our doors provide superior security compared to standard wood doors.

Window & Door Questions

Will replacing windows make a mess inside my house?

Our crews use drop cloths to protect floors and furniture, and we vacuum the work area thoroughly before we leave. We also wipe down and clean the new windows so they look sparkling and brand new.

What is the difference between insert and full frame replacement?

An insert slides into your existing frame. A full frame removes the trim and the entire old frame down to the studs, best for rot or maximizing glass space.
