What You Get With Every Installation

Every window installation includes proper insulation, weatherproofing, and interior/exterior trim work. We don’t consider a job complete until everything looks and functions exactly as it should.

Most residential window installations take one to two days, depending on the number of windows and your home’s specific requirements. We can typically install 8-12 standard windows per day with a two-person crew. Larger projects or homes with custom window sizes may require additional time. We’ll give you an accurate timeline during our initial consultation based on your specific project. Weather can occasionally affect scheduling, but we plan installations during favorable conditions whenever possible to ensure quality work.
Connecticut’s climate demands windows that handle temperature extremes, humidity, and storm conditions effectively. Vinyl windows with double or triple-pane glass perform exceptionally well here because they resist moisture, don’t require regular painting, and provide excellent insulation. Low-E coatings help with energy efficiency year-round. For older homes, we sometimes recommend specific frame styles that complement the architectural character while delivering modern performance. The key is matching window specifications to your home’s needs and Connecticut’s demanding weather patterns.
Most Connecticut homeowners see 15-25% reductions in heating and cooling costs after installing energy-efficient windows. The exact savings depend on your current windows’ condition, your home’s insulation, and your heating/cooling system efficiency. Homes with single-pane windows or windows with broken seals typically see the largest improvements. We can estimate potential savings based on your current windows during our consultation. Many homeowners find that energy savings help offset the window investment over time, especially with rising energy costs.
Most standard window replacements in Ledyard don’t require permits when we’re replacing existing windows with similar sizes. However, if we’re changing window sizes, adding new windows, or working on structural modifications, permits may be necessary. We handle all permit applications and coordinate any required inspections as part of our service. We’re familiar with local building requirements and ensure all work meets or exceeds Connecticut building codes. You don’t need to worry about the paperwork – we take care of those details.
You receive two types of warranty protection with our installations. Manufacturer warranties typically cover the windows themselves for 10-20 years, depending on the specific product and components. This covers defects in materials and manufacturing. We also provide our own installation warranty covering our workmanship, which ensures proper installation, weatherproofing, and function. If any installation-related issues arise, we return to address them at no charge. Having both warranties gives you complete protection on your window investment.
Absolutely. Many Connecticut homes have non-standard window openings, especially older homes built before modern standardization. We measure each opening individually and can order custom-sized windows when needed. Sometimes we can modify openings slightly to accommodate standard sizes, which can save costs while maintaining the home’s character. We’ve worked with everything from historic homes to unique architectural styles throughout southeastern Connecticut. Each project gets individual attention to ensure proper fit and performance regardless of your home’s age or design.
