Pennsylvania's climate demands windows that can handle a range of temperatures and precipitation. Summers can be hot and humid, requiring good insulation against heat gain, while winters bring cold and moisture, necessitating excellent sealing to prevent drafts and heat loss. Proper installation ensures that your double hung windows create an effective barrier against these elements. We focus on detailing the seals and ensuring a tight fit.
The housing stock across Pennsylvania varies, from historic homes in Philadelphia to more modern constructions. Older homes may present unique challenges due to their original framing, which can be less uniform. Our process includes a thorough assessment of these existing conditions. We adapt our installation techniques to accommodate these variations, ensuring a secure and weather-tight fit for every window, regardless of the home's age or style. Permitting may vary by municipality; we ensure compliance.
