Our Window Maintenance
Services
Routine window care is more than cleaning glass. Our certified window maintenance technicians inspect, lubricate, reseal, and adjust every moving part so your windows perform the way they did on day one. Each window maintenance service is tailored to your window type, age, and condition.
Window Inspection and Diagnostic Check
Every visit starts with a full window inspection that pinpoints air leaks, failing seals, hardware wear, glazing cracks, and early signs of wood rot. You receive a clear diagnostic report with prioritized fixes before small issues turn into costly repairs.
Caulking Between House Wall and Window Frame
Failed perimeter caulk is a top cause of drafts and water infiltration. We remove old, cracked sealant, clean the joint, and apply high-grade, weather-resistant caulking rated for freeze-thaw cycling to tighten your building envelope.
Silicone Application Between Sash and Glass
When silicone between the sash and glass dries out, the seal that blocks air and holds the pane gradually fails. We remove deteriorated silicone, clean the channel, and apply fresh, flexible glazing sealant for a watertight bond.
Window Hardware Maintenance
Cranks, balancers, locks, hinges, handles, and patio door rollers all wear down with use. We clean, lubricate, adjust, and replace minor parts so your windows operate smoothly, lock securely, and keep your home safe and easy to use.
Weatherstripping Replacement
Worn weatherstripping silently drives up heating and cooling bills. We replace compressed, brittle, or missing seals along sashes and frames with quality materials matched to your window brand, cutting drafts and easing the load on your HVAC.
Sash and Track Cleaning and Lubrication
Dirt, debris, and dried lubricant make windows stick and scrape. We clean tracks, remove old grease, and apply manufacturer-approved lubricants that keep double-hung, sliding, and casement windows operating effortlessly for years.
Seal and Glazing Inspection
Foggy glass, cracked glazing compound, and soft spots around insulated glass units signal early seal failure. We catch these issues so we can reseal, re-glaze, or recommend insulated glass unit replacement before condensation or wood damage takes hold.
Pre-Winter and Pre-Summer Tune-Ups
Seasonal window maintenance is one of the smartest investments a homeowner can make. Our pre-winter and pre-summer tune-ups combine inspection, sealing, lubrication, and adjustment into one visit timed to protect your home before harsh weather hits.

Words from Our Clients
FAQ About Window Maintenance
How often should windows be professionally maintained?
Annual window maintenance is recommended for most homes, ideally before winter sets in. Older wood windows and homes in harsh climate zones may benefit from twice-yearly tune-ups to catch seasonal wear early.
How much does window maintenance cost?
Most window maintenance visits in the Chicago area fall between $150 and $500, depending on the number of windows, their condition, and the services needed. Apex Window Werks provides free written estimates before any work begins.
Can window maintenance really lower my energy bills?
Yes. The U.S. Department of Energy reports that windows are responsible for 25–30% of residential heating and cooling energy use, and sealing drafts, replacing weatherstripping, and restoring glazing all directly reduce that loss.
Do you maintain commercial windows too?
Yes. Our commercial window maintenance services cover storefronts, office buildings, retail spaces, and historic commercial properties throughout Chicago and surrounding suburbs.
