Energy-efficient window replacement installed with proper flashing, sealing and finish work.
About this service
Old windows leak air, collect condensation and drive up energy bills. We replace them with energy-efficient units, flashed and sealed correctly so the wall stays dry and the room stays comfortable.
Windows do more than let light in. They are part of the building envelope, and when they are old, poorly installed or leaking, they cost you comfort and money every month. At Avany Contractors we replace windows with the wall assembly in mind—not just the sash.
We start by inspecting the existing windows, frames, flashing and surrounding wall for rot and moisture. From there we recommend full-frame or insert replacement based on the condition of the opening, then help you choose glass packages and finishes that fit the home and your budget.
Installation is where most window problems begin. We set every unit level and square, flash the opening correctly, seal the perimeter and finish the interior trim so the result looks original. Exterior details are coordinated with siding, stucco and trim so water sheds away from the wall. Serving New Jersey and Pennsylvania from our Trenton base, we protect the interior, clean up daily and stand behind the work.

Insert windows are a good fit when the existing frame and flashing are sound. Full-frame replacement is the better choice when there is rot, failed flashing or a need to correct the rough opening. We inspect first and explain both options.
Most homes are completed in one to three days, depending on the number of windows and whether full-frame work is required. Larger projects are scheduled in phases so the house stays secure each night.
Modern glass packages and proper sealing reduce air infiltration and heat transfer, which can lower heating and cooling costs. The biggest gains come when the installation is flashed and sealed correctly, not just when the glass is upgraded.
