What's Included With Installation

Every window installation includes proper weatherproofing, insulation, and trim work. We don’t cut corners on the details that determine how well your windows perform long-term.

You get windows sized specifically for your home’s openings. Older Connecticut homes often have non-standard window sizes, so custom fitting is crucial for energy efficiency and appearance.

We handle permits if needed and make sure everything meets local building codes. Your installation comes with warranty coverage on both materials and our work, so you’re protected if any issues come up.

Most window replacement projects take one to two days depending on the number of windows and any complications we encounter. A typical home with 10-12 windows usually gets completed in a day and a half. We work efficiently but never rush the important details like weatherproofing and proper sealing. Weather can sometimes delay exterior work, but we’ll keep you informed if that happens. We always clean up completely each day so your home stays livable during the installation process.
Spring through fall offers the best weather conditions for window installation, but we work year-round when needed. Late spring and early fall are often ideal because temperatures are moderate and there’s less chance of extreme weather delays. Winter installations are definitely possible and sometimes necessary for emergency replacements. We just take extra precautions to minimize heat loss during the installation process. If you’re planning ahead, scheduling for late spring gives you the full summer to enjoy improved comfort and efficiency.
Energy savings depend on what you’re replacing and how inefficient your current windows are. Homeowners typically see 15-25% reductions in heating and cooling costs after replacing single-pane or very old double-pane windows. In Connecticut’s climate, the heating season savings are usually most noticeable. Windows with poor seals or damaged frames waste the most energy, so those replacements show the biggest improvement. The exact savings vary by home size, window count, and your current energy usage, but most customers notice lower bills within the first few months.
We handle permits when they’re required, though many window replacements in Connecticut don’t need permits if we’re replacing existing windows with similar sizes. When permits are necessary, we pull them and make sure all work meets local building codes. We’re familiar with Fitchville and New London County requirements, so we know what’s needed before we start. Any permit costs are included in your estimate upfront – no surprise fees later. If an inspection is required, we coordinate that and make sure everything passes the first time.
We inspect the window openings carefully before starting and let you know if we spot potential issues. Sometimes removing old windows reveals minor rot or damage that needs attention before installing new windows. When this happens, we discuss your options and provide pricing for any necessary repairs. We carry insurance that covers accidental damage during installation. Most window replacements go smoothly, but we’re prepared to handle unexpected issues professionally and transparently. The goal is always to leave you with properly installed windows regardless of what we encounter.
Signs you need new windows include drafts you can feel, condensation between glass panes, windows that stick or won’t stay open, and rising energy bills despite normal usage. If your windows are more than 20 years old and you’re noticing comfort issues, replacement probably makes sense. Physical damage like cracked glass, rotting frames, or broken hardware are obvious indicators. Sometimes the biggest clue is simply that certain rooms stay too hot or cold no matter how you adjust the thermostat. We can assess your current windows and help you decide which ones need immediate replacement versus which ones can wait.
