What You Get With Every Installation

Every window installation includes proper removal of old windows, disposal of materials, and complete weatherproofing for Connecticut weather. We handle permits when required and ensure all work meets local building codes.

You’ll receive manufacturer warranties on the windows themselves plus our installation warranty covering our workmanship. We install vinyl, fiberglass, and wood windows depending on your preferences and budget.

Poquetanuck homes often need custom sizing due to older construction. We measure precisely and order windows that fit correctly rather than trying to make standard sizes work. Your windows should fit your home, not the other way around.

Window replacement costs vary based on window size, type, and how many you’re replacing. Basic vinyl double-hung windows typically start around $400-600 per window installed, while premium options can run $800-1200 or more. The biggest cost factors are window quality, size, and any structural work needed during installation. We provide detailed estimates that break down material and labor costs so you know exactly what you’re paying for. Most Poquetanuck homeowners find that quality windows pay for themselves through energy savings within 8-12 years.
Connecticut requirements vary by municipality, but most window replacements need permits when you’re changing window sizes or doing structural work. Simple like-for-like replacements often don’t require permits, but it’s worth checking with Preston’s building department to be sure. We handle permit applications when needed and ensure all work meets Connecticut building codes. The permit process typically takes 1-2 weeks and costs $50-150 depending on the scope of work. Skipping required permits can cause problems when you sell your home, so it’s better to do this right from the start.
Connecticut’s climate demands windows that handle temperature extremes, high humidity, and occasional severe weather. Vinyl windows perform well here because they don’t expand and contract as much as other materials, and they never need painting. Double-hung and casement styles are most popular because they’re easy to clean and provide good ventilation. Look for windows with Low-E glass coatings and argon gas fills for better energy efficiency. We typically recommend windows rated for at least 140 mph wind speeds and tested for air infiltration below 0.3 cubic feet per minute to handle Connecticut winters properly.
Most residential window installations take 1-3 days depending on how many windows you’re replacing and whether any structural work is needed. We can typically install 8-12 windows per day in straightforward situations. Older homes sometimes require additional work if we find rotted framing or need to adjust openings for new window sizes. We’ll give you a realistic timeline during the estimate and let you know if we discover anything that might extend the schedule. Weather can delay exterior work, especially during Connecticut winters, so we plan installations around favorable conditions when possible.
Quality windows installed properly can reduce heating and cooling costs by 15-25% in most Connecticut homes. The actual savings depend on what you’re replacing and how drafty your current windows are. Single-pane windows or windows with failed seals offer the biggest opportunity for improvement. Modern double or triple-pane windows with Low-E coatings and proper installation eliminate drafts and reduce heat transfer significantly. Most homeowners notice the difference immediately – rooms stay more comfortable and heating systems don’t run as frequently. The monthly savings add up over time, typically paying for the window investment within 8-15 years.
You get two separate warranties with professional window installation. The window manufacturer provides warranties on the glass, frames, and hardware – typically 10-20 years depending on the brand and window type. We provide our own installation warranty covering our workmanship, usually for 2-5 years depending on the project scope. This covers issues like air leaks, water infiltration, or installation-related problems. Manufacturer warranties are only valid when windows are installed by certified contractors following their specifications. We’re certified with major window manufacturers and ensure installations meet warranty requirements so your coverage stays intact.
