"Excellent experience from start to finish! The team was professional, friendly, and arrived on time. They did an amazing job cleaning our windows—they're absolutely sparkling, and I didn't realize how much brighter the house would look afterward. They were careful, efficient, and left everything clean when they finished. I highly recommend this company to anyone looking for quality window cleaning and outstanding customer service. I'll definitely be using them again!"

"Here is the short of it: Ben from Jammin Films was quick to quote my job, extremely responsive and knowledgable when answering my questions, and was able to meet my request to have the window films installed within 5 days of being quoted. I am extremely happy with the work and am having him do more of our West facing windows, as well as, install Bird Film to prevent the birds from flying into our windows and getting hurt! Cannot recommend enough, support small business whenever able!"

Customers say: Quick response

"I have been hiring contractors for decades and these guys are among the best... and their pricing was excellent. On time, did exactly what they said, great work, great people, when they were finished, the new egress window looked better than I could have hoped, and they covered the room and cleaned to the point you would never have known that I just had the window put in. Can't give them a high enough referral. I can see that it's no coincidence that all their reviews are 5s... just hire them. No question that I would hire them again."

"Our window started leaking after a big rain storm and I wasnâ t able to isolate the source of the leak. Jason came out the same day and was able to identify the issue with the caulk around the glass. He answered all of our questions and provided a very reasonable quote which they came back to fix the following week after the window had dried out. We had a couple other windows we were worried about sealed at the same time. Great service and workmanship! I would recommend them for all your window and glass needs."

Windows FAQs, answered by experts

Window replacement is typically always worth the cost, both from a money-saving standpoint and a comfort standpoint. If your windows are older and significantly damaged, a window replacement can actually save you money in the long term by improving energy efficiency. If your windows aren’t up to code, you may not really have a choice. 

Visibility through tinted house windows or privacy film depends on the lighting. During the day, the tint or film typically prevents people from seeing inside. However, at night, if you have lights on inside your home, the interior will be brighter than the outside, which allows people to see in. You can choose from various shades of privacy film, from lighter to darker, to optimize the level of privacy you want.

Mold on windows forms due to excess moisture from condensation, poor ventilation, or leaks. Cold glass surfaces can attract condensation, especially in winter. High indoor humidity, lack of airflow, or dust accumulation are also contributors. To prevent mold growth, improve ventilation, regularly clean sills, and consider using a dehumidifier or sealing any leaks.

Yes, window manufacturers and installers can mull together three windows—or even more—for a more impressive appearance that lets maximum natural light into your home. However, you may have constraints regarding the total size of the wall opening. Your installer can help you determine what size wall opening is safe based on the structural load. In most cases, you can install additional supports to span the opening, like a steel I-beam, but this drastically increases the installation cost.

Hot water removes grime more efficiently than cold water and evaporates more quickly so that your windows will dry faster. However, you may want to use cold water instead if your windowsill paint is chipping or peeling because heat can worsen this condition.
