Your heating and cooling bills drop because your HVAC system isn’t working overtime to compensate for leaky windows. Those cold spots and drafts disappear, making every room comfortable.

You stop worrying about whether your windows are properly sealed or if moisture is getting where it shouldn’t. The installation is done right, with attention to flashing, insulation, and weatherproofing details that matter.

Your home looks better from the street, and you know the value has increased. More importantly, you’re not dealing with the frustration of windows that don’t open smoothly, fog up, or let in noise from outside.

Oxoboxo River Window Company

We Know Connecticut Windows

Sullivan Contracting has been handling window installations throughout Connecticut for years. We understand how New England weather affects window performance and what it takes to install them properly in our climate.

We’re not a national chain that rotates through different crews. You work with the same local team from consultation through completion. We live and work in this area, so our reputation depends on getting it right.

Most of our work comes from referrals because homeowners see the difference when windows are installed by contractors who know what they’re doing.

Window Installation Process

Here's How We Handle Your Project

We start with a consultation at your home to assess your current windows and discuss your goals. You get straightforward information about options, timeline, and cost without any pressure tactics.

Once you’re ready to move forward, we handle permits and schedule the work around your availability. On installation day, we protect your floors and furniture, remove old windows carefully, and install new ones with proper flashing and insulation.

We clean up completely and walk through the finished work with you. You get care instructions and warranty information. The whole process typically takes one to two days for most homes, depending on the number of windows.

What's Included in Every Installation

Every window installation includes proper removal of old windows, disposal of old materials, and complete installation with weatherproofing. We handle flashing, insulation, and trim work to ensure everything looks finished and performs properly.

You get windows that are level, square, and properly sealed. We test every window to make sure it opens and closes smoothly and locks securely. All necessary permits are pulled and inspections are coordinated.

Connecticut’s weather demands attention to detail during installation. We use proper sealants and flashing techniques that hold up to freeze-thaw cycles and heavy rain. Your installation is designed to last, not just look good on day one.

How long does window installation take for a typical home?

Most residential window installations take one to two days, depending on the number of windows and any complications we encounter. A typical home with 10-15 windows usually takes a full day if everything goes smoothly. Larger homes or projects requiring custom trim work may extend into a second day. We’ll give you a realistic timeline during the consultation based on your specific situation. Weather can affect the schedule since we need dry conditions for proper installation, so we build some flexibility into our scheduling during Connecticut’s unpredictable seasons.

What's the difference between window replacement and new construction windows?

Replacement windows are designed to fit into your existing window frame, while new construction windows include the entire frame assembly. Most homeowners need replacement windows unless they’re building new or completely renovating. Replacement windows are more cost-effective because we don’t need to rebuild the opening or do extensive exterior work. They’re specifically engineered to fit standard existing openings and provide the same energy efficiency as new construction windows. The installation is faster and less disruptive to your home’s interior and exterior finishes.

Do you handle permits and inspections for window installation?

Yes, we pull all necessary permits and coordinate required inspections as part of our service. Most window replacements in Connecticut require permits, especially if we’re changing the size of openings or doing structural work. We know the local requirements in Oxoboxo River and surrounding areas, so you don’t have to navigate the permit process yourself. The permit costs are included in our project estimate, and we schedule inspections to keep your project moving forward. This ensures your installation meets all local building codes and protects your investment.

How much can new windows actually save on energy bills?

Energy savings depend on your current windows and home, but most homeowners see a 15-25% reduction in heating and cooling costs with properly installed energy-efficient windows. If your current windows are single-pane or more than 20 years old, the savings can be even higher. The biggest impact comes from eliminating air leaks and improving insulation values. Connecticut’s climate means you’re heating and cooling for most of the year, so even modest efficiency improvements add up quickly. We can give you a more specific estimate based on your current windows and home size during the consultation.

What happens if there's damage to the wall when removing old windows?

Minor repairs around window openings are normal and included in our installation process. We often find small areas that need attention once old windows are removed – things like rotted sill plates or gaps in insulation. These repairs are part of doing the job right and ensuring your new windows perform properly. If we discover significant structural issues that weren’t visible during the initial assessment, we’ll discuss options with you before proceeding. Our goal is to leave you with windows that are properly installed and sealed, which sometimes means addressing underlying issues that would affect performance.

Should I replace all windows at once or do them in phases?

Replacing all windows at once is usually more cost-effective and ensures consistent appearance and performance throughout your home. You get better pricing on materials and labor, and the work is completed faster with less disruption overall. However, budget considerations sometimes make phased replacement necessary. If you need to phase the work, prioritize windows that face prevailing winds or get the most sun exposure, as these typically have the biggest impact on energy costs and comfort. We can help you prioritize which windows to replace first based on their condition and your home’s specific needs.
