Frequently Asked Questions
Do I need to replace the entire window or can I just use a pocket insert?
If the existing window frame, sill, and surrounding structure are in excellent condition and properly sealed, a pocket insert replacement is faster and less intrusive. However, if there is rot, water damage, or significant air leakage around the frame, a full-frame replacement is necessary to maximize energy efficiency and structural integrity.
Are certain window styles more energy-efficient than others?
Generally, fixed picture windows are the most energy-efficient. Among operating windows, casement and awning windows, which seal tightly by pressing the sash against the frame when closed, tend to be more airtight than double-hung or slider windows.
How long does it typically take to install new energy-efficient windows?
For a typical home with 10 to 15 windows, professional installation usually takes one to three days. The exact duration depends on the window type, accessibility, and whether any structural modifications are required.

“As a professional engineer having 33 years of experience in the NYC construction industry, I can be at times over critical when having work performed at home. Issues like scheduling work, attention to detail, and trying to get fair value for the work performed can be troublesome. Well, NOT with P J Sullivan. I was given an initial estimate and schedule and they meet both as promised. Their (and especially Peter and brother Dan Sullivan’s) attention to detail exceeded my expectations! They really do strive for perfection. Having our home renovated by Peter and Co. was effortless. I can’t say enough about how pleased my wife and I are with the work performed by PJS.”- John C.

“The scope of our job entailed a new roof, James Hardie siding (cobblestone), a new stone chimney and front stoop (Old New England), copper chimney shroud, half-round bronze aluminum gutters, new garage doors, and lighting. The job took 2.5 months from start to finish and PJ Sullivan Construction was a great partner to work with. They were organized in the execution of each piece of the project and offered excellent aesthetic input for all of the design details. The tradespeople used for various aspects of the work were all professional, easy to work with and the area was always kept clean at the end of each workday. The final outcome was exactly what we had hoped for. Peter Sullivan is very easy to communicate with and made himself a real partner with a vested interest in a successful outcome.”- Nina S.
