Window Weatherproofing in NW Bergen County

Providing Comfort and Efficiency in Wycoff, Saddle River, & the Surrounding Areas

Windows are not only portals to the outside world; they also play a crucial role in maintaining the comfort and energy efficiency of your home. However, without proper weatherproofing, windows can become sources of energy loss, drafts, and moisture infiltration, leading to increased heating and cooling costs, reduced indoor comfort, and potential damage to your home's interior.

At PJ Sullivan Exteriors, we offer premium window weatherproofing services that can help homeowners in the Tri-State area maintain a comfortable indoor environment while increasing energy efficiency and prolonging the lifespan of their windows.

Why Window Weatherproofing is Essential

Weatherproofing your windows helps protect your home against harsh New Jersey weather conditions, including heavy rain, wind, and temperature fluctuations. Properly sealed windows prevent air leaks, keep your indoor climate stable, and reduce the risk of mold or water damage. PJ Sullivan Exteriors uses high-quality caulks, sealants, and insulation methods tailored to each window type for long-lasting results.

How Can I Tell If My Windows Need Weatherproofing?

Homeowners often notice these signs indicating a need for weatherproofing:

  • Drafts or cold spots near windows
  • Condensation or moisture buildup on window panes
  • Increased energy bills during summer or winter
  • Difficulty opening or closing windows due to swelling or misalignment

    Pete is a pleasure to work with, and all of his work, and the work of his team, is top quality. His design suggestions are always insightful.
    “I hired Pete Sullivan more than three years ago to help replace a small section of siding on my suburban house in New Jersey. Since then, he has not only replaced all the siding and roofing on my house, but completely renovated the entire interior, a multiyear job that included moving many walls, installing new tiles for the entire first floor, completely renovating the kitchen, and building a new gas fireplace and a custom cabinet for a TV lift. He most recently finished renovating a second-floor bathroom. Pete is a pleasure to work with, and all of his work, and the work of his team, is top quality. His design suggestions are always insightful. Our next project is to install updated heated and cooling systems, as well as a solar collector.”
    - Jason F.
    We were extremely happy with the work that PJ Sullivan Construction did for us. We would be happy to hire him again.
