You know the feeling when you walk past that one window and feel the cold air seeping through. Or when your energy bill arrives and you wonder why you’re paying to heat the outdoors.

The real payoff comes over time. Lower energy bills, month after month. No more fighting with painted-shut frames or dealing with condensation that won’t go away. Just windows that work the way windows should work.

Window Installation Process

Here's Exactly What Happens

First, we measure your existing windows and discuss your needs – energy efficiency, style preferences, and budget. No pressure, just straight information about what works best for your situation.

Once you’re ready to move forward, we order your custom-sized windows and schedule installation around your timeline. Most installations take one day per window, depending on the size and any structural issues we find.

On installation day, we protect your floors and furniture, remove old windows carefully, and install new ones with proper insulation and weatherproofing. We clean up completely – you shouldn’t know we were there except for your new windows.

After installation, we walk through everything with you, explain warranty coverage, and make sure you’re satisfied with how everything looks and operates.

Every window installation includes proper removal of old windows, professional installation with appropriate flashing and insulation, and complete cleanup. We handle permits when required and make sure everything meets local building codes.

You’ll get manufacturer warranties on the windows themselves, plus our labor warranty covering the installation work. We use quality caulking and weatherstripping that holds up to Connecticut’s temperature swings.

Most Colchester homes have standard window sizes, but we handle custom sizing for older homes with non-standard openings. If we find any structural issues during removal, we’ll discuss options before proceeding – no surprise charges after the fact.

We’ll give you a realistic timeline during the initial consultation based on your specific situation.
Spring through fall offers the best weather conditions for window installation in Connecticut, but we work year-round when needed. Winter installations are possible but take longer due to weather precautions and the need to minimize heat loss during the process.

We’ll work with you to find the best timing for your schedule and budget.

However, if we’re changing window sizes, adding new windows, or making structural modifications, permits may be required. We handle the permit process when necessary and make sure all work meets local building codes. During our initial consultation, we’ll let you know if permits are needed for your specific project.

Most Colchester homeowners invest between $400-800 per window including installation, though larger or specialty windows cost more.

The investment typically pays for itself through energy savings over 5-10 years, especially if you’re replacing single-pane or very old windows.
Double-hung vinyl windows with low-E glass perform well in Connecticut’s climate extremes.

The exact savings depend on your current windows’ condition, your home’s insulation, and energy usage patterns. Modern windows with low-E coatings and proper installation eliminate drafts and reduce heat transfer significantly. We can estimate potential savings based on your current windows during the consultation.
