"Estimate went well. Darren was very thorough. Explained the process and provided the estimate of $8,018 for window and installation. Explained that it came with a LIFE TIME WARRANTY. Explained that financing would be 24 months no interest and processed with Momnt and took the first $4,000 as downpayment - 50/40/10. Josh came back a few days later, remeasured and took some of my indoor framework down (pealed paint but at the time didn't make a fuss). August 31st, received an updated contract changing from triple pane to double pane and changing outside color. Received a text from Dave Oct 2 saying that my materials were expected to arrive Oct 12. Said they would keep me updated which they have not! I have reached out several times only to get the runaround! I finally sent a message to Darren only to be told that they had shut down the Billings Office and even if my materials were here, there would be no one to install nor anyone to honor the warranty! After finding out that the lady down the street had been left in the same situation as me but with a whole house project, I reached out to you."

Windows FAQs, answered by experts

You will need about half of a caulking cartridge to caulk one window. The average home has eight to 10 windows, so you would need about 4 or 5 cartridges to caulk every window in an average-sized house. However, you may not need to caulk all the windows at once. If just one window has a pesky draft, you may only need half of a cartridge to fill in the gaps.

Contrary to popular belief, wavy glass in older homes isn't caused by warping. The blowing technique used to create windows in homes dating back to the 1700s, 1800s, and early 1900s left behind small bubbles that create a wavy effect. If a glass window is functional, there's no need to consider wavy glass damaged. In fact, many homeowners prefer the old charm of wavy glass.

The amount of time window lintels last is based on the environment they’re installed in and the material that’s installed. For example, a steel lintel installed in a temperate climate will always last longer than a wooden or brick lintel installed in an area with tons of rain, snow, and wind. No matter which material you choose or where you live, proper maintenance will ensure your lintels last as long as possible.

Generally speaking, you should clean your windows and any associated fixtures and treatments every six months. Otherwise, clean them as needed to keep everything running smoothly. If you live in a part of the country with especially hard water, you may have to clean them three or four times per year, and the same goes for areas where insects, pollen, dirt, and other debris can soil your windows and potentially cause issues with the moving parts.

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.
