"This is our second "phase" of window replacement and we used Zen Windows once again. High quality products, excellent service, and the install was once again flawless. Plus no dealing with salespersons selling marked up windows, then playing pricing games which still cost more. It's a pleasure to work with Scott and Zen Windows."

"Windows and sliding doors cleaning were great. Power wash included gutters which really needed it! Small issue of a broken flood bulb was resolved the next day and the resolution was above and beyond expectations. Will using them again on the spring!"

"We detected over the past six what we thought was a "fogging" of the window film Atlantic installed approx. 10 years ago.  Before calling them for an inspection to confirm/refute our suspicions, we had the windows (approx. 36) professionally cleaned inside and out.  We then called Atlantic to inspect the window film issue and they did so promptly.  After ruling out window seal failure, Atlantic agreed that the window film they had installed was defective and had fogged. (They traced it back to a problem "run" from the manufacturer.)  We scheduled a removal/re-install date with them and - as they say - the rest is history.  Truly no hassle and no cost. These folks are the best!  Recommend/use them again?  You betcha!

Windows FAQs, answered by experts

Bay windows are expensive mostly because their above-average size means higher material costs. Unlike bow windows, most bay windows also include casement windows on either side of a picture window, and the opening mechanisms for casement windows drive up costs. You’ll also pay higher labor costs to install a bay window, as you’ll often need multiple technicians to lift the window into place.

Egress windows are typically required for basements with habitable space or living quarters. Not all basements or lower levels require egress windows. However, egress windows are required in homes with living spaces such as bedrooms and living rooms in a basement. The International Residential Code and International Building Code require sleeping rooms to have a specific size egress window. Check your local building codes to confirm the requirements in your area.

Replacing window glass instead of the entire window is more cost-effective, maintains the frame's aesthetics, and reduces waste. It improves insulation and energy efficiency and can be completed more quickly with minimal disruption to the home.

You should board up windows when you need to protect your home either from intruders after a window breaks or from severe weather before you experience damage. To maintain home security with a broken window, get your window boarded immediately. If there’s a hurricane, tropical storm, or tornado expected in your area, board your windows a day or two beforehand to avoid emergency service fees.

Your new windows may let in more noise than your old windows because they are not the right size or they were installed improperly. Improper installation, or choosing windows that are too small for the opening, can create gaps around the window that let in noise.

Another factor could be the STC and OITC ratings. If your new windows have lower ratings than your old windows, this means they have lower performance when it comes to dampening noise from the outdoors.
