Here's How We Handle Installation

First, we measure everything twice. Your windows get custom-sized because standard sizes rarely fit older Norwich homes perfectly. No forcing square pegs into round holes.

Installation day starts with protecting your floors and furniture. We remove old windows carefully – no unnecessary damage to your siding or interior trim. Each new window gets properly flashed and sealed before we move to the next one.

The final step is cleanup and walkthrough. You’ll know how to operate your new windows, what warranty coverage you have, and how to reach us if anything needs attention. Most installations finish in one day, weather permitting.

What's Included With Installation

Every window installation includes proper insulation around the frame, exterior caulking, and interior trim work to match your existing style. We don’t consider a window “installed” until it operates smoothly and seals completely.

You get manufacturer warranties on the windows themselves – typically 10-20 years depending on what you choose. Our installation work carries its own warranty because we stand behind the quality of our crews.

Norwich homes often need custom solutions. Older houses have settling, non-standard openings, or architectural details that require experience to handle properly. That’s exactly the type of work we do regularly.

Most residential window installations finish in one day, assuming we’re replacing 8-12 windows. Larger homes or complex architectural features might extend into a second day. Weather delays are possible – we won’t install windows in rain or when temperatures are too extreme for proper sealing. We’ll give you a realistic timeline during your estimate, and we stick to it. The key is having everything measured and ordered correctly beforehand so installation day runs smoothly.
We work with several quality manufacturers that perform well in Connecticut’s climate. The specific brand matters less than choosing windows rated for our weather conditions – proper insulation values, strong frames, and reliable hardware. During your consultation, we’ll explain the differences between vinyl, wood, and composite options based on your budget and maintenance preferences. We don’t push one brand over another; we recommend what makes sense for your specific situation and home style.
Most window replacements in Norwich don’t require permits when you’re replacing existing windows with similar sizes and styles. However, if you’re changing window sizes, adding new openings, or doing structural modifications, permits become necessary. We handle permit applications when required and make sure all work meets local building codes. During your estimate, we’ll clarify whether permits are needed for your specific project and factor any costs into your quote.
Window installation costs depend on window quality, size, and how many you’re replacing. Basic vinyl windows might run $400-600 per window installed, while premium options with advanced features cost $800-1200 or more. Older Norwich homes sometimes need additional work – trim repair, siding adjustments, or structural modifications – which affects pricing. We provide detailed written estimates that break down material and labor costs so you understand exactly what you’re paying for.
We carry full liability insurance specifically for this reason. If our crew damages your property during installation, our insurance covers repairs. That said, damage is rare when installation is done properly. We protect floors, furniture, and landscaping before starting work. Most “damage” people worry about is actually planned removal of old trim or siding that needs replacement anyway. We’ll explain what to expect during your estimate so there are no surprises on installation day.
Yes, but with weather limitations. We can install windows when temperatures are above freezing and conditions are dry. Sealants and insulation materials need proper temperatures to cure correctly. We typically avoid installation during active storms, extreme cold snaps, or when ice makes roof work dangerous. If you’re planning winter installation, we’ll monitor weather forecasts closely and communicate any necessary schedule adjustments. Most homeowners prefer spring through fall installation, but winter work is possible with the right conditions.
