No matter the age or style of your home, windows that draft, fog, or fail to open and close properly are a problem — one that compounds with every Illinois winter. B.W. Construction & Home Improvement has provided window replacement services to St. Charles homeowners since 1997. As the only Pella Platinum Premier Certified contractor in Illinois, we offer a premium window selection, professional installation, and strong warranty coverage — including a two-year parts and labor warranty on qualifying projects. ‍ ## Window Replacement Services in St. Charles We install Pella [replacement windows](https://www.bwconstructionhome.com/service-area/replacement-windows-st-charles-il) in four materials, each suited to different needs and budgets: - **Wood windows** — warm, beautiful interiors with excellent insulation; the right choice for historic and traditional St. Charles homes - **Vinyl windows** — durable, low-maintenance, and energy-efficient - **Fiberglass windows** — strong and stable through Illinois' temperature extremes - **Aluminum-clad windows** — a tough exterior finish with a refined wood interior Available in double-hung, casement, picture, sliding, and specialty styles, our window options are selected to complement the character of your St. Charles home while improving long-term performance. ‍ ## Signs Your St. Charles Home Is Due for Window Replacement You don't always need a professional inspection to know your windows are underperforming. Common warning signs include: - Drafts or cold air coming through around the frame in winter - Condensation or visible fogging between panes (a sign of seal failure) - Frames that are warped, rotting, or deteriorating - Windows that stick, won't lock, or rattle in the wind - Energy bills that seem high for the size of your home When multiple issues are present, window replacement is almost always more cost-effective than patching problems one at a time. ## The Window Replacement Process at B.W.
