"I highly recommend Windo-Well Cover Co. They were here when they said they would be, came prepared do the job even if it rained, and went above and beyond by cleaning out the window well before installing the cover. I am happy with the look of the cover, but am especially pleased with the strenth and durability of the cover. We will use them again to cover additional window wells."

"F and A did a fantastic job cleaning our windows and doors! The communication was great, they arrived on time and cleaned every glass surface, sills, and screens until they looked almost new. It was wonderful to walk into the house and see the sun and plants through sparkling clean windows. We will hire F and A to clean our windows every spring!"

"The installers were great. The salesperson made promises that he did not keep and he missed a window. When the person came to measure he also didn’t catch that I was having all my windows done except one. The windows look great. The response when I notified the co that one window was missed was very fast but added to my cost."

"They cleaned our 8 Pane windows on our two story 1940â  s house perfectly with the exception of one window which it seems they forgot and I missed when I inspected before they left. The guy that came out was professional and did great work. He stuck with our original quoted price even though upon arrival he realized that this was an old house me with multi pane windows and outdoor storm windows on each. Windows looks ok great and I will give a second review after I hear back on the missed window from the company"

"We have once again reached out to Joe Kim at J & K Home Improvements when we had a new project planned. We were completely satisfied when we replaced our siding and roof with Joe. Now Joe and his professional crew have replaced all our windows . There are never surprises or additions from when the job is quoted. Once again we are totally satisfied and delighted with their work!! It has been a stress free experience each and every time."

Windows questions, answered by experts

Using plastic shrink film over the window will cut down on drafts, which makes the air inside your home feel warmer. Plastic shrink film doesn’t quite have the insulative properties of a new window or of adding insulation inside the window jamb, but it will help. Plus, it’s a cost-effective solution to keeping your home warmer.

There are a few reasons your crank windows might not close. First, determine if your window crank is working properly and opening and closing the window when you turn it. If it’s not, the crank may need replacing, cleaning, or lubricating. Another reason your windows aren’t closing could be dirt and debris in the window hinges or sash. Finally, make sure your window lock operator is set in the unlocked position and isn’t blocking the window from fully closing. If you’re still having trouble closing your window, it may be worth consulting a local window contractor.

There are many standard window sizes. The most common windows, single or double-hung models, typically range from 2-feet by 3-feet up to 4-feet by 6-feet. Of course, sliding windows will be wider than they are tall, though the standard sizing follows the same measurements.

Picture windows are still in style, even though they are one of the oldest types of windows. Other windows, like single- or double-hung windows and casement windows, have increased in popularity because they can open up for fresh air. However, homeowners still love the way a picture window can frame their lush outdoor garden or other pleasant neighborhood views.

You can choose 5/8-inch plywood or 3/4-inch plywood—anything thinner than these sizes may not withstand the impact of debris propelled by strong winds or can be easily torn off by intruders. Remember that the durability of the wood board is crucial, particularly for safeguarding your windows during severe storms. The effectiveness of using wood boards for protecting the investment you made in your home relies on using the appropriate material and ensuring proper installation.
