Replacement Windows in McLean, VA

For most McLean homes, window replacement work takes anywhere from a few days to two to three weeks, depending on the number of windows, the complexity of each opening, and whether any frame or exterior finish work is needed. A single-window job might take a few hours. A whole-home project in a large McLean property may be scheduled across multiple days to maintain the quality of workmanship. Kelemer Brothers will provide a timeline during your estimate.

McLean sits in the mid-Atlantic climate zone, with warm, humid summers and moderate winters. ENERGY STAR certified windows with low-emissivity (low-E) glass are the best choice because they reflect summer heat while retaining interior warmth in cooler months. For homes near highway corridors, laminated or high-performance glass can significantly reduce outside noise. Double-hung, casement, and picture windows all perform well when built with the right glass package. Your Kelemer Brothers consultant can recommend the best option based on your specific room and goals.

For like-for-like replacement (same size, same location), Fairfax County Department of Land Development Services (LDS) typically does not require a permit. If you are changing the size of an opening, adding a new window, or installing an egress window, a permit is required. Kelemer Brothers reviews the specific requirements for your project during the estimate and handles all permit applications at no additional cost.

Look for visible signs: condensation or fog between the glass panes, cold drafts near windows even when they are closed, windows that are hard to open or close, visible rot or deterioration in the frames, or difficulty locking windows. If your home was built in the 1960s or 1970s with original windows, or if previous replacement windows are now 25-30 years old, a professional evaluation is a good investment. Kelemer Brothers’ free in-home assessment will give you a clear picture of each window’s condition.

Yes. Kelemer Brothers performs window replacement year-round, including winter months. Installation in colder weather requires careful attention to sealants and weather conditions, but with proper technique it is just as durable as summer work. Some homeowners actually prefer winter installation because scheduling is more flexible. Discuss timing preferences during your estimate.

Full-frame replacement removes the entire existing window, including the frame and trim, and installs a new window system in the opening. Pocket or insert replacement keeps the existing frame and trim in place and installs a new window sash inside it. Full-frame is more invasive but allows for better sealing and finish work, especially if the existing frame is damaged. Pocket replacement is faster and causes less disruption but is only possible if the existing frame is sound. Kelemer Brothers will assess your windows and recommend the best approach for each opening during your consultation.

Savings depend on the current condition of your windows, the new window’s energy performance, and your home’s size and orientation. Homes with many south- or west-facing windows, or homes near I-495 where you are running air conditioning harder to combat noise and heat, can see noticeable reductions in cooling costs. ENERGY STAR windows in McLean’s climate can reduce heating and cooling costs by 10 to 30 percent compared to older, single-pane or inefficient windows. Kelemer Brothers can discuss your specific situation during the estimate.

Yes. Every window Kelemer Brothers installs as standard is ENERGY STAR certified for the Northern climate zone, which covers McLean, Fairfax County, and all of Northern Virginia. ENERGY STAR certification is issued by the U.S. Environmental Protection Agency based on independent testing data — not the manufacturer’s self-reported specifications. That distinction matters: a window marketed as “energy efficient” by its manufacturer may or may not carry actual ENERGY STAR certification. Kelemer Brothers’ products do.

Kelemer Brothers features Vytex Windows as a primary product line for Virginia projects. Vytex is a premium vinyl window manufacturer with strong ENERGY STAR ratings, a comprehensive manufacturer’s warranty, and a track record of long-term performance in the mid-Atlantic climate. Kelemer also works with other quality manufacturers depending on project-specific requirements. Your project consultant will present available options with honest performance and value comparisons so you can make an informed choice.

Quality vinyl replacement windows installed correctly last 20 to 40 years in Northern Virginia’s climate. Frame integrity, glass seal quality, and installation quality are the primary variables. Vinyl frames do not rot, warp, or require painting. The insulating glass seal — the component most vulnerable to failure over time — lasts 15 to 25 years with quality units and proper installation. Kelemer Brothers’ lifetime workmanship warranty means that if an installation-related issue contributes to a performance problem at any point, they will address it at no cost.

Yes. Kelemer Brothers offers financing for qualified McLean homeowners so a large project does not have to mean depleting savings or waiting until the budget clears. Financing terms and availability are reviewed during your free in-home estimate. There is no pressure to commit to any financing arrangement — or to any decision at all — during the estimate visit.

Yes. Kelemer Brothers holds a Virginia contractor’s license and carries full general liability insurance and workers’ compensation coverage on every project in the state. Virginia law requires contractor licensing for home improvement work above specific thresholds. Request a copy of their license and certificate of insurance during your estimate.

Kelemer Brothers serves McLean proper, Langley, Chesterbrook, Salona Village, McLean Gardens, Kentlea, the Chain Bridge Road corridor, Spring Hill, Turkey Run, and the Dolley Madison Boulevard corridor. If you are unsure whether your address falls in the service area, call (410) 299-0038 — the answer for McLean and the surrounding area is almost always yes.

There is no minimum. If a single window has failed — a fogged seal, a broken sash, a frame that will not close — Kelemer Brothers will replace it. Single-window replacements carry a modest per-unit premium compared to whole-house projects, which Kelemer Brothers is upfront about, but there is no policy that forces you into a larger project than you need.
