"Excellent job on the window tinting project. The quality of the work is top- notch, clean precise and professionally done. The tint not only enhanced the look of the home but has reduced the glare and heat, just as I had hoped. Cassandra was respectful of our space and left everything spotless after the job was done. I’d highly recommend to anyone looking to upgrade their home Windows. Outstanding work with a fun personality!!"

Windows questions, answered by experts

Most standard windows can accommodate solar screens, but specialty shapes or non-standard frames may require custom solutions. It’s important to consult with a professional to ensure compatibility and proper fit for unique window designs. Arched, bay, and fabricated windows often need fabricated screens, which can increase costs and lead time.

Before purchasing, it’s good to weigh the pros and cons of vinyl windows. Vinyl windows offer several advantages over other types of windows. Vinyl windows are more affordable than most other window types, and they’re also very energy efficient. Vinyl windows are also low-maintenance, weather-resistant, and easy to install.

Water leakage through window openings is much more common in older homes, but it can also create issues with window frames that are improperly installed. If left unattended, water buildup can cause damage to surrounding fixtures, lead to harmful mold, and compromise the architectural integrity of your home. The potential damage that a water leak poses makes investing in weather- and water-proofing your window frames entirely worthwhile.

Whether or not you need permission to change the windows in your house depends on your local laws. If you’re enlarging an opening or installing a new window and need to make structural changes to the house, you’ll need a permit. In most locations, you won’t need permission if you’re just replacing a window with another window of the same size. The window installation company you work with will be able to help you navigate any planning permits you may need.

The biggest disadvantages of low-E windows have to do with cost and, depending on your personal taste, appearance. Low-E windows cost more than traditional windows—typically between $300 and $1,000 per window, plus installation costs. Though they can save you money in the long run, low-E windows have a hefty upfront price tag. Additionally, low-E windows have a slightly different look than traditional windows. While some people don’t notice it, others say the low-E coating gives windows a hazy look.
