Key Benefits of Our Window Replacement Services in Philadelphia
Philadelphia’s Urban Continental climate puts real strain on windows: below-freezing winters with 22 inches of annual snow, salt air from treated roads, 90°F+ summers, and the moisture challenges that come with densely packed rowhome neighborhoods. Since 2003, Monarch Contractors has been replacing windows across the city — from historic Colonials in Chestnut Hill to rowhomes in South Philly to condos in Northern Liberties. Every project comes with a dedicated project manager, transparent pricing, and warranties that protect your investment long-term.
Hassle-Free Window Replacement Experience
We manage every aspect of your project — from measuring your home’s window openings and pulling required building permits to final installation and cleanup. Whether you’re replacing one window in a South Philly rowhome or all 18 in a Chestnut Hill Colonial, our crew works around your schedule and leaves your home exactly as they found it.
Your Windows, Our Commitment
Every project starts with a written contract that locks in your timeline, cost, and full scope of work — no surprise charges, no vague estimates. We specialize in both residential and commercial replacements throughout the Greater Philadelphia area, delivering transparent communication from your first call to final walkthrough. Lifetime warranty on workmanship, period.
Trust Certified Window Experts
With 20+ years serving homeowners across the region, our certified installers know local building codes, historic district requirements, and the specific challenges of rowhome construction — narrow access, shared walls, and brick-frame openings. From emergency single-pane replacements to full custom window designs, no job is too complex.
10-Year Quality Assurance
We install only premium double and triple-pane insulated glass units rated for local freeze-thaw cycles, backed by manufacturer warranties up to 30 years and our own 10-year installation guarantee. Every window we install — residential or commercial — is built to handle whatever the season brings.
