Hear from Our Customers
You’ll notice the difference the moment we finish. No more fighting with windows that stick or won’t stay open. No more cold drafts sneaking through gaps in winter or hot air creeping in during summer.
Your energy bills drop because your HVAC system isn’t working overtime to compensate for inefficient windows. The house stays comfortable without constant thermostat adjustments.
New windows also mean fewer maintenance headaches. No more scraping, painting, or wrestling with warped frames. Modern materials handle Connecticut weather without the constant upkeep that older windows demand.
Sullivan Contracting has been handling window installation projects throughout Chesterfield and surrounding Connecticut communities for years. We understand how Connecticut’s weather affects windows and what installation techniques work best here.
Our team focuses on getting the job done correctly rather than rushing to the next project. We measure twice, install once, and make sure everything operates smoothly before we leave.
You’re working with local contractors who live in the same area and understand what homeowners here actually need from their windows.
We start with precise measurements at your home. Every opening gets measured because even small variations matter for proper fit and performance. You’ll get a detailed estimate that covers everything upfront.
Installation day starts with protecting your floors and furniture. We remove old windows carefully, prep the openings, and install your new windows with proper sealing and insulation. Each window gets tested to ensure smooth operation.
Cleanup happens as we work, not after we leave. You’ll have functioning windows and a clean home at the end of each day. The whole process typically takes one to two days depending on how many windows you’re replacing.
