• Should I Repair or Replace My Windows?

  Should you repair or replace your windows? The answer depends on what is actually failing. A broken lock, worn weatherstripping, damaged screen, or isolated glass seal failure may be repairable, while recurring drafts, deteriorated frames, difficult operation, water problems, multiple failed glass units, or outdated window performance can make replacement the better long-term investment. JR Girskis, President and Owner of Suburban Construction, recommends evaluating the entire window rather than replacing a window simply because it is old.

• Why Do Windows Feel Cold Without Drafts?

  A window can feel cold even when no outside air is leaking through it. The reason is often surface temperature, not a draft. During a Quad Cities winter, cold outdoor temperatures can cool the interior glass surface enough that your body radiates heat toward the window, creating the sensation of a cold draft even when the window is tightly sealed. Better glass packages, including Low-E and triple-pane options, can help raise interior glass temperatures and improve comfort near the window.

• How Much Can Replacement Windows Reduce Outside Noise?

  Replacement windows can noticeably reduce outside noise, especially when replacing older single-pane, loose-fitting, or poorly sealed windows. However, there is no honest universal percentage because noise reduction depends on the existing windows, glass thickness and configuration, number of panes, laminated-glass options, frame construction, installation quality, and the frequency of the sound. Suburban Construction offers double-pane, triple-pane, and laminated-glass options and recommends visiting the Davenport showroom to compare window construction and glass packages before choosing a replacement window.

• Why Is There Condensation Between My Window Panes?

  Condensation between window panes is different from moisture on the inside or outside surface of the glass. If the fog or moisture is trapped between panes and cannot be wiped away, it can indicate a failure of the insulated-glass seal. Suburban Construction specifically lists window seal failure and condensation between panes as a common service issue and can help determine whether the glass unit may be serviceable under a manufacturer warranty or whether window replacement makes more sense.

• Why Are Window Replacement Estimates So Different?

  Window replacement estimates can vary dramatically because contractors may be quoting different window brands, frame construction, glass packages, installation methods, trim work, warranties, and service levels. For Quad Cities homeowners in Davenport, Bettendorf, Moline, Rock Island, East Moline, and surrounding Iowa and Illinois communities, the smartest comparison is not simply the lowest price—it is the complete window system, installation scope, and long-term support.

• Why Does Ice Form on the Inside of My Windows?

  Ice on the inside of a window usually forms when warm, humid indoor air reaches glass or frame surfaces that are cold enough for condensation to freeze. In Iowa and Illinois winters, indoor humidity, outdoor temperature, window efficiency, air leakage, installation quality, and airflow around the glass can all affect whether frost or ice develops. Learn what Quad Cities homeowners should check before assuming their windows need replacement.

• What Window Options Help Protect Furniture from UV Fading?

  Modern Low-E replacement windows can help reduce ultraviolet (UV) rays that contribute to fading of furniture, hardwood floors, rugs, and artwork. Learn which glass options provide the best protection and why professional installation is just as important as the glass itself.
