"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

Yes, selecting double glazing or low-E coatings to reduce energy costs.

To lower your home’s humidity level overnight, you can open your windows when the air is less damp. This tactic allows air to circulate around the window, preventing condensation from forming. However, you should consider the disadvantages of leaving your windows open overnight, including safety risks and pest intrusions.

Yes, you can always make an existing window bigger, but the job complexity varies widely depending on the location of the window and the framing around it. Exterior walls are always load-bearing, so making windows wider will require structural changes that make for a more complex but doable project. Making windows taller often won’t require structural changes.

Whether you need a permit to install a bay window depends on the project's scope. Replacing an existing bay window typically does not require a permit. However, if you are adding a new bay window, requirements can vary. Adding a new bay window to the front of your house usually requires a building permit, while adding one to the side or back of your house often does not. It's always best to check with your local municipality to confirm the specific requirements in your area. Additionally, if you live in a historic district, you should consult your neighborhood association to ensure your project complies with their construction guidelines. If you're unsure about the process, a professional can provide guidance.

Garden windows last about 15 to 30 years, depending on the materials, ongoing maintenance, and local climate. Fiberglass and wood windows tend to have the longest life spans as long as you keep up with cleaning, lubricating, and refinishing them. Make sure to inspect your windows about once a year for signs of trouble, like worn-out seals, frame damage, or cracks in the panes.
