Serving the NYC Metro Area & Long Island Since 2008 | $11 Million Liability Coverage

We know Long Island architecture.

Long Island isn’t just one architectural style — it’s a vast stretch of coastal properties, historic estates, and modern commercial parks. Salt air, coastal storms, and expansive landscaping require a specialized approach to exterior maintenance. You need a vendor built to protect your investment from the elements.

Coastal & waterfront homes

From the South Shore to the Hamptons, salt air corrodes window hardware and degrades thermal seals. We specialize in foggy glass and IGU replacement and corrosion-resistant hardware restoration to keep your ocean views clear.

Expansive North Shore estates

White-glove care for luxury properties. We use ultra-lightweight, deionized pure-water pole systems to safely clean multi-story windows and skylights from the ground, helping protect landscaping and garden beds from heavy ladder traffic.

Corporate parks & office buildings

Serving major business hubs in Melville, Hauppauge, and Garden City. We deploy operated aerial lifts and specialized commercial teams for mid-rise window cleaning and atrium glass maintenance with minimal disruption to corporate operations.

Busy retail & shopping centers

Keep your storefront inviting. We deliver rapid glass replacement, emergency board-up service, and hot-water pressure washing for high-traffic retail corridors and shopping plazas across Nassau and Suffolk counties.

Useful information

  • Do you service both Nassau County and Suffolk County?

    Yes, our Long Island window cleaning covers all of Nassau County and Suffolk County. We regularly service homes in Garden City, Manhasset, Huntington, East Hampton, and everywhere in between. Our teams are familiar with Long Island’s estate properties, waterfront homes, and seasonal residences. Minimum window requirements may apply for far eastern Suffolk County locations.

  • How much does solar panel cleaning cost on Long Island?

    Solar panel cleaning typically costs $150-400 depending on system size, roof pitch, and accessibility. Most Long Island residential systems need 2-4 hours of service annually. Dirty panels lose 15-25% efficiency from pollen, bird droppings, and dust accumulation. We use deionized water and soft-wash techniques to avoid scratching, ensuring maximum energy production from your investment.

  • Can I clean my solar panels myself, or should I hire professionals?

    While possible, DIY solar cleaning risks panel damage, roof safety issues, and voided warranties. Walking on roofs near panels is dangerous, especially on steep pitches common in Long Island homes. Improper cleaning solutions or tools scratch anti-reflective coatings. Professional service costs less than efficiency losses from damaged panels. Most Long Island homeowners schedule annual professional cleaning.

  • Do you offer combined window washing and power washing services?

    Yes, many Long Island homeowners schedule window cleaning and power washing together for convenience and efficiency. We can clean your home’s windows, then power wash driveways, patios, decks, and siding during the same visit. Coordinating services saves scheduling time and often costs less than separate appointments. Spring is our busiest season for these combined services.

  • Is it worth restoring old windows in historic Long Island homes?

    For historic estate homes with original craftsmanship, restoration often preserves architectural value while improving function. Original wood windows in Gold Coast mansions or vintage homes can be restored for $400-800 per window versus $600-1200 for quality replacements. However, severely rotted frames or completely failed mechanisms may cost more to restore than replace. We assess honestly.

  • What's the average cost for vinyl replacement windows on Long Island?

    Vinyl replacement windows typically cost $400-800 per window installed, depending on size, quality, and features. A 2000 sq ft Long Island home averages 15-20 windows, so full replacement runs $8,000-16,000. Higher-end vinyl with better insulation, warranties, and hardware costs more but performs better. Replacing all windows simultaneously usually offers better per-window pricing than piecemeal replacement.

  • Are there tax credits for window replacement in 2026?

    Energy-efficient window installations may qualify for federal tax credits up to $600 under the Inflation Reduction Act, extended through 2032. Windows must meet ENERGY STAR certification and specific U-factor/SHGC ratings. Long Island homeowners should verify current requirements with tax professionals, as programs change. Some utility companies also offer rebates for energy-efficient upgrades.

  • Can window replacement be claimed on homeowners insurance?

    Insurance typically covers window replacement only when caused by covered perils like storms, vandalism, or accidents – not age or maintenance issues. Check your deductible first, as it may exceed replacement costs. Many Long Island policies require wind/hail damage documentation. Normal wear, deterioration, or efficiency upgrades aren’t covered. Save all documentation if filing claims

  • How much does window cleaning cost for Long Island estate homes?

    Estate homes with 40-100+ windows typically cost $600-2000+ depending on window quantity, size, accessibility, and special features like multi-pane French doors or hard-to-reach conservatory glass. We provide detailed estimates after assessing your specific property. Many Long Island estate owners schedule quarterly service to maintain pristine appearance year-round.

  • Do you clean windows at Long Island seasonal properties?

    Absolutely. We service seasonal homes in the Hamptons, North Fork, and Fire Island communities. Many owners schedule opening and closing cleanings – spring service before arrival, fall service before winterizing. We coordinate with property managers and caretakers for access. Storm windows, screens, and shutter preparation can be included in seasonal service visits.

     

    <H3> What window problems are common in Long Island waterfront homes?

    Issue Cause Solution
    Salt residue buildup Ocean/bay salt air exposure Quarterly cleaning with specialized solutions
    Frame corrosion Salt accelerating metal deterioration Regular maintenance, protective coatings
    Seal failure (foggy glass) Humidity and temperature extremes Replace failed units, prevent with proper ventilation
    Screen deterioration Salt and wind damage Replace or repair damaged screens
    Hard water spotting Sprinkler systems hitting windows Reposition sprinklers, glass restoration treatment

    Waterfront properties require more frequent maintenance than inland Long Island homes.

  • Should I replace 20-year-old windows on my Long Island home?

    Probably. Windows from 2005 lack modern efficiency standards. If experiencing drafts, condensation, difficult operation, or high energy bills, replacement makes financial sense. Technology improvements in the past 20 years – Low-E coatings, argon gas, better seals – deliver substantial energy savings. Most Long Island homes see 15-25% heating/cooling cost reduction with modern windows.

  • How do you access windows on Long Island multi-story homes?

    We use extension ladders, water-fed poles up to 50 feet, and occasionally boom lifts for extremely high or difficult access situations. Most Long Island estate homes have ground-accessible windows or upper windows that tilt inward for cleaning. Our teams assess each property individually and use the safest, most efficient method for your specific home design.

  • Do you clean greenhouse and conservatory windows on Long Island?

    Yes, greenhouse and conservatory cleaning is a specialty service we provide throughout Long Island. These structures accumulate dirt, pollen, and algae quickly, reducing light transmission for plants. We carefully clean glass panels, frames, and ventilation systems without damaging plants or structures. Many Long Island estate properties with greenhouses schedule quarterly maintenance.

  • What's included in your Long Island window cleaning service?

    Our comprehensive service includes interior and exterior glass cleaning, frame and sill wiping, screen removal and cleaning, squeegee drying for streak-free results, and careful debris removal. We bring all equipment, professional cleaning solutions, and floor protection. Any stuck-on materials like paint or stickers get removed. You receive crystal-clear windows from SPRAT-certified professionals with $11M insurance coverage.
