Window Repair and Glass Replacement in McLean VA

Glass Replacement

In McLean, tiny hairline cracks, a foggy haze between panes, or surprise condensation on a chilly morning aren’t “just cosmetic.” They quietly drain comfort, increase HVAC load, and—if ignored—can invite drafts, mildew, and safety risks. Local weather swings matter here: summers are warm and humid, and winters can be cold and snowy, which puts constant stress on glass units and seals.

Below are five of the most common glass problems we see in McLean homes, what’s really happening behind the scenes, and how our team restores performance without the runaround.

Broken or Cracked Glass

One fracture weakens the entire pane, allowing conditioned air to escape and reducing security. We remove the damaged lite and install a precision-cut, energy-rated replacement—often in one visit—bringing back clarity, strength, and insulation.

Foggy Double-Pane Window

That milky blur between panes usually means a failed insulated-glass unit (IGU). We replace the compromised IGU with a factory-sealed, gas-filled panel designed to restore your view and cut heat transfer.

Failed Window Seals (Blown IGU)

When perimeter seals fail, invisible gaps steal warmth and invite moisture. We locate the breach, replace the seal—or, if saturation is advanced, the full IGU—then reseal the sash so efficiency stays locked in.

Condensation on Interior Glass

Persistent “sweat” on the room side often points to indoor humidity plus temperature differentials. We install modern glass options (like low-E and warm-edge technology where appropriate) and recommend ventilation tuning to reduce drip lines and mold risk.

Noise Penetration repair

Beltway traffic, Parkway flow, and everyday neighborhood noise can cut straight through thin or poorly fitted glass. We install sound-reducing glass options and tighten perimeter seals to reclaim calm indoor spaces—especially in rooms facing busy roads.

Seasoned glaziers, certified installers, and detail-driven project leads power our service team. We use premium materials, follow manufacturer-aligned methods, and provide a written workmanship guarantee before we pack up. Expect punctual arrivals, careful protection of your floors and furnishings, spotless cleanup, and windows that look—and perform—like new for years in your McLean home.

Rotted Frame Repair

Moisture-softened wood, warped jambs, peeling paint - frame issues rarely stay small. They can let water creep into walls, invite drafts, and quietly raise your energy spend month after month. Here are the most common frame failures we repair in McLean, why they happen, and what it takes to restore structure and comfort.

Rotting Window Frame repair

When wood fibers stay damp, they soften and crumble. We remove decayed sections, treat what’s still sound, and install primed replacement material sealed against future moisture intrusion.

Warped or Cracked Frame repair

Seasonal expansion and contraction can twist frames out of square. We plane or replace affected components, re-square the opening, and secure everything so sashes align correctly and seals stay tight.

Window Peeling Paint

Blistered paint is more than cosmetic - it exposes wood to moisture and UV. We prep properly (scrape, sand, prime) and apply a durable exterior-grade finish designed to hold up through Virginia’s sticky summers and winter cold snaps.

Drafty Window Repair

Gaps from shrinking wood, aged weatherstripping, or loose stops can siphon heat in winter and cool air in summer. We install new seals, reset stops, and close perimeter gaps for a noticeable comfort upgrade.

Leaky Window Repair

Water doesn’t need a big opening - micro-cracks and failed caulk lines are enough. We trace the intrusion path, reseal correctly, and add smart water-management steps (like improved flashing details where needed) so rain stays outside.

You’ll get straightforward recommendations, clean workmanship, and a clear written warranty on the work we perform.

Window Hardware Repair

Loose locks, wobbly handles, and groaning hinges aren’t just annoying - they’re gateways for drafts, moisture, and security worries. Left alone, hardware problems strain frames, ruin alignment, and chip away at your window’s lifespan. Here are the five hardware failures we see most often in McLean - and how we restore smooth, secure operation.

Broken Locks or Latches

If the sash won’t stay shut, security and efficiency both drop. We install profile-matched replacement hardware, realign the keeper, and confirm a crisp, one-handed lock.

Damaged Handle

Cracked levers and stripped set screws make operation feel like a workout. We replace fatigued components and tighten everything so opening the window feels effortless again.

Worn or Broken Hinges

Sagging hinge arms drag the sash and compromise seals. We replace hinges, correct alignment, and test movement so the window swings cleanly without scraping.

Faulty Window Balances (Springs)

When balances fail, sashes slam shut or creep down - dangerous for kids and pets. We size and install correct balances and tension them so the sash stays exactly where you set it.

Malfunctioning Crank Operators

Seized gears can freeze casements and awnings in place. We replace worn operators, clean tracks, lubricate pivot points, and restore full ventilation range.

We arrive with well-stocked vans and precision tools, so most hardware repairs can be completed in a single visit - followed by a full function check and a spotless cleanup.

Sill and Sash Repair

Swollen sashes that won’t budge, windows that slide down like a guillotine, frames tilted just enough to whistle in the wind - sill-and-sash issues waste energy and can become a real safety risk. Below are the headaches we fix most often in McLean homes, why they happen, and how we get it right the first time.

Window Stuck Shut / Won’t Open

Old paint buildup, grit in tracks, or slight warping can lock a sash in place. We remove binding material, clean channels, lubricate friction points, and re-square the sash so it glides smoothly.

Window Won’t Stay Up (Balance Failure)

Broken springs or frayed cords create a slam hazard. We replace and calibrate balances, then cycle-test until the window holds steady at every height.

Poor Installation

A frame that was never truly square will leak, rattle, and wear out faster. We correct alignment with precision shimming, reseat the sash, and seal perimeter joints for a snug close.

Our technicians use alignment tools and best-practice repair methods, then leave you with a window that feels solid, looks right, and operates cleanly year after year.

Window Screen Services

Custom Screen Fabrication & Installation

Missing screens, bent frames, rattling inserts - if the frame is shot, a re-mesh won’t help. We measure each opening and build custom-fit window screens that sit flush and stay quiet. Choose durable aluminum framing, clean corners, and low-profile hardware for easy removal and simple cleaning - perfect for families who want fresh air without pests.

Screen Mesh Replacement & Performance Upgrades

If the frame is solid but the mesh is torn, cloudy, or sagging, re-screening is the smart move. We can install standard fiberglass, sturdier options (including pet-resistant mesh), and clearer-view materials, then tension everything for a tight, neat finish that improves airflow and keeps bugs out.

Storm Window Services

Storm Window Installation & Full Unit Replacement

Storm windows add a protective, energy-saving layer without changing your primary window.

Storm Pane (Glass) Replacement & Resealing

Cracked or fogged storm glass undercuts insulation and invites moisture. We replace the glass, review glazing and weather seals, and confirm proper fit so the storm layer actually performs like it should.
