What You Get With Every Installation

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

You’ll receive manufacturer warranties on the windows themselves plus our installation warranty. This covers both the products and our workmanship so you’re protected if anything goes wrong.

We handle all the details including permits if needed, disposal of old windows, and final cleanup. Chesterfield homeowners appreciate not having to coordinate multiple contractors or worry about disposal logistics. You get professional installation from start to finish without the typical hassles that come with home improvement projects.

Most residential window installation projects take one to two days depending on the number of windows and any complications we discover. A typical home with 10-12 windows usually gets completed in a single day if everything goes smoothly. Larger homes or projects requiring structural adjustments might extend into a second day. We’ll give you a realistic timeline during the estimate so you can plan accordingly. Weather can affect scheduling since we need dry conditions for proper installation and sealing.
Vinyl and fiberglass windows perform exceptionally well in Connecticut’s climate because they handle temperature swings without warping or expanding like some materials do. Double or triple-pane glass with low-E coatings helps with energy efficiency during both hot summers and cold winters. We typically recommend windows with strong weather sealing and quality hardware that won’t fail after a few years of use. The specific style depends on your home’s architecture and your preferences, but the materials matter more for long-term performance.
Window replacement costs vary based on window size, style, materials, and how many you’re replacing. Most Chesterfield homeowners spend between $400-800 per window including installation, though larger or specialty windows cost more. Energy-efficient upgrades often qualify for utility rebates that reduce your net cost. We provide detailed estimates that break down material and labor costs so you understand exactly what you’re paying for. Financing options are available if you prefer to spread payments over time rather than paying upfront.
Most standard window replacements in existing openings don’t require permits in Chesterfield, but we verify requirements for each project during the estimate process. If permits are needed, we handle the application and coordinate inspections so you don’t have to deal with town offices. Projects involving structural changes or egress window installations typically need permits and inspections. We stay current on local building codes and requirements so your installation meets all regulations without delays or complications.
You get two separate warranties with every installation. The window manufacturer provides product warranties that typically cover materials and components for 10-20 years depending on the brand and model you choose. Sullivan Contracting provides installation warranties covering our workmanship and labor. This protects you if installation issues develop like air leaks, water infiltration, or operational problems caused by improper installation. Both warranties give you recourse if problems develop, which is why professional installation matters more than just buying windows online.
We can install windows year-round in Connecticut, but winter installations require extra precautions and favorable weather windows. Temperatures need to be above freezing for proper sealant curing, and we avoid installation during storms or extremely cold snaps. Winter projects take longer because we work more carefully to minimize heat loss during installation. Many homeowners prefer spring and fall installation when weather is more predictable, but emergency replacements can’t always wait for perfect conditions. We’ll advise you on timing based on your specific situation and local weather forecasts.
