What's Included With Your Installation

Every window installation includes proper removal of old windows, disposal of materials, and complete weatherproofing of the new installation. We handle all the trim work and touch-up painting around the window frame.

You get windows that are specifically chosen for Connecticut’s climate. We make sure they’re level, square, and sealed correctly so they’ll perform well for decades. All hardware is installed and adjusted so everything operates smoothly.

We also handle any permit requirements and make sure the installation meets local building codes. Franklin has specific requirements for window installations, and we know exactly what’s needed to pass inspection.

How long does window installation typically take?

Most window installations take one to three days depending on how many windows you’re replacing and the complexity of the job. Single-story homes with standard-sized windows usually get done faster than multi-story homes or installations that require custom sizing. We give you a realistic timeline upfront and stick to it. Weather can occasionally delay exterior work, but we’ll communicate any changes immediately. The actual installation process for each window typically takes 45 minutes to an hour once we get started.

What type of windows work best in Connecticut?

Vinyl and fiberglass windows perform best in Connecticut’s climate because they handle temperature swings without warping or expanding. Double-hung and casement styles are most popular because they’re practical and energy-efficient. We recommend double or triple-pane glass with low-E coating to handle our cold winters and humid summers. The key is getting windows that are properly sized and installed with adequate insulation around the frame. Wood windows look great but require more maintenance in our climate.

How much will new windows save on energy costs?

Most homeowners see 10-25% reduction in heating and cooling costs after replacing old windows with energy-efficient models. The actual savings depend on what you’re replacing and how drafty your current windows are. Single-pane windows from the 1980s or earlier typically provide the biggest savings opportunity. Your HVAC system won’t have to work as hard to maintain comfortable temperatures, which extends its lifespan too. We can show you energy ratings for different window options so you can make an informed decision.

Do I need permits for window replacement in Franklin?

Most window replacements in Franklin don’t require permits if you’re replacing existing windows with similar sizes. However, if you’re changing window sizes, adding new windows, or doing structural modifications, permits are typically required. We handle all permit applications and inspections when they’re needed. Franklin’s building department is straightforward to work with, and we know exactly what documentation they require. We’ll let you know upfront if permits are necessary for your specific project.

What warranty comes with new window installation?

Window manufacturers typically provide 10-20 year warranties on materials, with some offering lifetime warranties on certain components. Our installation work is guaranteed for two years, covering any issues related to weatherproofing, operation, or installation quality. If something isn’t working right, we come back and fix it at no charge. We only work with manufacturers that stand behind their products long-term. Keep your warranty documentation – it’s important for both material defects and installation issues.

Can you install windows during winter months?

Yes, we install windows year-round in Connecticut, including winter months. We use temporary coverings to protect your home’s interior during installation and work efficiently to minimize heat loss. Some homeowners actually prefer winter installation because they can immediately feel the difference in comfort and energy efficiency. We avoid installation during severe weather conditions for safety and quality reasons. Interior temperature stays manageable during installation, and you’ll notice improved comfort immediately once the new windows are in place.
