"Great customer service they arrived on SAID time ON time. They didn't leave until the job was completed. I spotted one small flaw but nothing to complain about other than that they did a great job. They cleaned up behind themselves. I had to disposed of all the trash myself but they did put all the trash in bags and sat them outside nice and neat and it was also in the contract that the customer is responsible for disposal of trash. It was not a surprise. This properly why the cost was reasonably priced. I will use them again."

Customers say: Quick response

"Quick response to my request on Friday and demolition the next Monday. The demolition and removal took less than an hour. I am pleased because the dilapidated shed was in the way of my next home improvement project. I told Alan I was leaving for vacation Monday morning. He was on site at 7:15 am."

Windows FAQs, answered by experts

Yes, every window needs a lintel. The lintel is necessary for redistributing the load above the window to the walls around the window. Windows aren’t meant to support a load, so lintels are an important part of a window installation. If you go to replace your windows and discover there are no lintels, you may need a window company or structural engineer to install lintels for your new windows.

Yes, you can install a bay window in an existing house. You’ll need to have a structural engineer draw up plans to add the necessary support to your exterior load-bearing walls and a general contractor to make the changes to the framing around the new wall opening. This will cost an average of $3,000. After that work is done, a window installer can set the new bay window in place.

A good U-factor for windows is 0.30 or lower, but they can range from 0.20 to 1.20. A general rule of thumb when it comes to the U-factor is that the lower, the better.

Making a window in a basement larger costs an average of $4,200. You’ll need to pay an average of $550 to have a structural engineer plan the project, $500 to $1,500 for the installation labor, and an average of $2,200 for the excavation and window well installation. The remainder will go toward pulling permits, installing trim, and repairing drywall on the interior.

The gas between window panes, typically argon or krypton, acts as a barrier to heat transfer. This means it helps keep your home warmer in the winter and cooler in the summer by preventing heat from passing through the glass. This gas layer also reduces condensation by stabilizing the temperature across the window and helps minimize noise. Essentially, it’s all about improving energy efficiency and comfort while lowering those utility bills.
