The benefits of our window caulking services
Exterior window caulking for commercial buildings in New York City offers numerous benefits, especially when it comes to window waterproofing and glazing for windows, greenhouses, and skylights. Proper caulking helps in preventing water infiltration, which can lead to costly damages such as mold growth, rot, and structural deterioration. In a city like New York with our varying weather conditions, high-quality caulking also provides protection against wind-driven rain and extreme temperatures, ensuring energy efficiency and maintaining a comfortable indoor environment. Additionally, caulking helps in reducing noise transmission, enhancing the overall comfort and productivity of occupants within commercial buildings.
Window caulking is the process of using a putty-like substance made from silicone elastomers to seal these air leaks around your windows. This not only puts an end to drafts, but also creates a nice, polished look. Window caulking is one of those home maintenance jobs that few people think of, but that can offer considerable savings in both energy usage and utility bills by sealing any gaps that may exist.

Saves You Money
Anytime anything saves us money, we listen. After all, the more money you save, the more money you will have to use for more important things, such as family vacations and activities you want to do. By ensuring your home or office building is as air tight as possible, you’ll be keeping that warm or cool air in, which saves on utility bills.
Keeps the Bugs Out
While bugs are a nuisance in your home, they can be horrible for businesses. Since many people do not like bugs and have the impression that bugs are dirty and are attracted to dirty items, having bugs in your commercial space can negatively impact your customers’ experience to the point they don’t come back. Total Window Service offers commercial window caulking in the heart of NYC for just this purpose.
Shores Up Your Windows
Buildings wear out just like any other item created by man, as attested to by the hundreds of run-down buildings you see when you drive out into the countryside all across the United States. By investing in residential window caulking services in Queens, Long Island, or Brooklyn, you’ll be filling spaces created over time by shifts in your building and helping your windows to stay in place for the long haul.
Why Window Caulking Matters
Over time, caulk wears out and leaves small holes through which air can seep in or out. With improperly caulked windows, you’ll find that in the summer, you have to run your air conditioner more to maintain cool temperatures inside. During the winter months, your heating bill may go up as your heated air escapes through these gaps. Any time of year, windows with poor or no caulking can let in annoying drafts.

How We Can Help
We’ll locate all your leaks and expertly caulk your windows to seal them correctly, ensuring that you’re not paying extra on your energy bills. First we’ll remove old, worn, and disintegrating caulking, if any is present, and we’ll follow that by applying fresh new caulking to close up holes and stop any drafts. After we’re done, you should notice a discernible difference in air and temperature comfort levels, as well as in energy savings.

What type of caulk do you use for exterior window sealing on NYC high-rise buildings?
For exterior applications on NYC buildings, we use commercial-grade silicone elastomeric caulk – not the standard hardware store variety. This material withstands NYC’s freeze-thaw cycles, UV exposure, and wind-driven rain without cracking or shrinking. For historic landmark buildings, we select sealants compatible with masonry and original window frames to meet Landmarks Preservation Commission requirements.
How often does exterior window caulking need to be replaced in New York City?
In NYC’s climate, exterior caulking on high-rise and commercial buildings typically lasts 5-10 years before it starts to crack, shrink, or pull away from the frame. Buildings on exposed corners or facing prevailing winds from the Hudson may need recaulking sooner. We recommend a visual inspection every 3-5 years – our technicians can assess caulk condition during a regular window cleaning visit at no extra charge.
Can your technicians reach exterior window joints on upper floors of a high-rise to apply caulk?
Yes. Our team includes SPRAT-certified rope access technicians and NYC DOB-licensed suspended scaffold supervisors – including founder Andriy Mykyta, certified #TSC17-70120. This means we can reach and properly seal window perimeters on any floor without the cost of erecting full scaffolding for the entire building.
Does exterior caulking work count toward Local Law 11 / FISP facade inspection requirements?
Caulking and glazing work can be part of a Local Law 11 (FISP) remediation scope when a Qualified Exterior Wall Inspector identifies failed sealants as a condition requiring repair. Total Window Service performs caulking as part of facade maintenance projects and can coordinate with your building’s QEWI to ensure the work is properly documented for DOB filing purposes.
Is your caulking work covered by insurance, and do you carry liability if water damage occurs after the job?
Yes. Total Window Service carries $10 million in general liability insurance plus a $5 million umbrella policy, which covers property damage claims. We provide a Certificate of Insurance (COI) before any project begins – a standard requirement for NYC co-ops, condos, and commercial building managers. All work is documented with before-and-after photos via CompanyCam for your records.
Can exterior caulking be done in winter, or do I need to wait until spring to book the service?
Caulking can be applied in temperatures as low as 40°F, which covers most of NYC’s non-winter months. However, during periods of frost or when surfaces are wet from rain or snow, application is not recommended – the sealant requires a dry, clean substrate to bond properly. We typically schedule exterior caulking work from April through November and advise booking in early spring before the busy season to avoid delays.
