"Paulo and his team were excellent. At first I was weary with the price of James Hardy Siding, but once it installed my house was transformed. They exceeding my expectations and have received numerous compliments from my neighbors and from people just passing by as the house stands out! After the hail storm, I also requested that Paulo and his team replace the roof. Once again, they were right on it and did an excellent job. I am now remodeling the inside of my house and I would not consider going with anyone else but Paulo. I forgot to mention that he also replaced all the windows in my house and I requested that he extend my front patio. He is a jack of all trades and we are very happy with his work."

"We were very pleased with their work, timing, and quality of workmanship. We have received many positive comments on the appearance of our home. It is a great feeling to look at the home and know it has been sealed well against the weather and elements. We are very glad we chose a long-life product and an experienced team to install it. We would readily recommend Colorado Siding Repair to anyone who wants a quality product installed well at competitives prices, by folks with great integrity."

"Jason was wonderful!! Turns out my problem was not a window but a window covering, he gently fixed and did not charge for time or labor. I would highly recommend Jason for his professionalism, speed in getting here, and overall demeanor and friendliness. He even said he would come to Fort Collins if I needed him when I make that move. Thank You for sending him my way. Roberta W. in Littleton, CO"

"Had to replace one window in a shower. Drew was out right away with an estimate and his price came in much lower, for the same window, than the other 2 quotes I received. In addition, he was able to install the window approx. 5 weeks before either of the other company's would have been able to. My contractor was so impressed with quality of work he asked for his information so that he can recommend to others. Highly recommend!"

We needed some additional work done in the house and worked with Forest who helped connect us with someone to take care of the additional work. I highly recommend and we will use again in the future!"

Window Door Contractors FAQs, answered by experts

Rescreening your porch can take a few hours to a whole day, depending on the size of the enclosure and the amount of screen that needs replacing. If you decide to have a professional handle the rescreening, be sure to get a timeline and a cost estimate so you know how long you’ll be without the screened-in space.

Most window screens last for about 10 to 12 years, assuming they are made from quality materials and receive proper care. The lifespan of common materials like fiberglass and aluminum can vary based on weather exposure, as constant sun or harsh winters can accelerate wear and tear. Regular cleaning and basic maintenance can help extend their life. Signs that a screen needs to be replaced include rips, tears, brittle or sagging material, fading, or a bent frame. While small tears can often be repaired, larger areas of damage typically mean it's time to replace the entire screen.

Typically every 10-15 years or whenever they show signs of wear and tear.

The steps to replace a retractable screen can vary, but these are the general steps: First, remove the screen cover to expose the screen mechanism and remove the clip that holds the screen in place. Next, depress the end of the screen mechanism so it releases from the door frame. Take your new screen and fit one end into the frame. You may need to rotate the mechanism to engage the spring before inserting the other end into the frame. Finally, pull the screen down the length of the door’s opening and lock it in place with the clip.

If you’re not an experienced DIYer, consider hiring a local patio repair contractor to rescreen your porch or sunroom. Unless you’re only repairing a small rip or hole, this project is not an easy job. A professional can also make recommendations for materials that will work best for your porch.
