Our Window Sealant Services


We focus on precise assessments, thorough preparation, and customized sealant solutions. Our approach ensures windows are tightly sealed to reduce air leaks and improve energy efficiency.

Consultation and Assessment

We begin by meeting with you to understand your specific needs. Our team inspects each window carefully, checking for gaps, cracks, and worn-out sealants that cause air leaks.


Using specialized tools, we measure the extent of air infiltration. This helps us identify problem areas that may not be visible at first glance. We also discuss your budget and timeline to tailor the service accordingly.


The consultation gives us a clear plan to fix leaks effectively. We ensure communication stays open so you know what to expect during the project.

Preparation and Surface Cleaning

Before applying new sealant, we clean the window frames and surrounding surfaces thoroughly. Dirt, dust, and old sealant residue must be removed to ensure proper adhesion.


We use tools like scrapers, brushes, and cleaning agents that are safe for your windows. This step prevents future sealant failure and extends the durability of our work.


Proper surface preparation helps the sealant bond tightly, creating a more effective barrier against air and moisture. We take care to avoid damaging the window glass or frame during cleaning.

Tailored Solutions for Residential and Commercial Properties

We offer different sealant types based on property needs. For homes, we use flexible, weather-resistant sealants that accommodate window movement. This keeps your interiors comfortable and lowers energy bills.


Commercial buildings often require stronger, industrial-grade sealants to withstand harsher conditions. We adjust our applications accordingly for large glass panels or unique window designs.


Our team customizes each job to fit your building’s architecture and climate challenges. This ensures the sealant performs well, whether for a family house or an office complex.

Identifying Air Leakage in Windows


Detecting air leaks early helps us keep homes comfortable and reduce energy waste. Knowing the signs, using proper detection methods, and understanding the impact on energy costs guide us in applying the right sealant.

Common Signs of Air Leakage


We look for drafts around window edges and frames. If you feel cold air in winter or hot air in summer near windows, that's a clear sign of leakage.


Condensation buildup inside window panes or uneven temperature near windows can also show air is escaping. Peeling paint and warped window materials sometimes point to leaks. You might also notice higher heating or cooling bills without other explanation. These signs warn us to check the window seals closely.


Techniques for Air Leak Detection


We often use simple tools like incense sticks or smoke pencils near window edges. If smoke wavers or gets pulled toward a gap, air is leaking.


Thermal cameras help us spot cold or hot spots around windows that the naked eye can miss. These cameras show temperature differences clearly.


Sometimes, a professional blower door test measures how much outside air enters the home through leaks. It gives precise data on window seal performance.


Impacts on Energy Efficiency


Air leaks cause your heating and cooling systems to work harder. Warm or cool air escapes, making energy use rise noticeably. Increased energy use raises utility bills, sometimes by 10-20% or more depending on leak size. It also shortens HVAC equipment life due to overwork.


Properly sealing leaks improves energy efficiency, maintains indoor comfort, and lowers costs. We focus on fixing these issues to protect your home’s energy performance.
