"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!"

Window Door Contractors FAQs, answered by experts

A garage door screen can be a worthwhile investment, especially if you frequently use your garage for activities like a home gym, workshop, or other hobbies. It allows you to enjoy fresh air and natural light without worrying about bugs. Additionally, a screen provides ventilation that can improve air quality when you're working with paints, varnishes, or producing sawdust.

The best option depends on your usage. For occasional use, a DIY fabric screen is a low-cost, simple solution that you can put up and take down as needed. If you plan to spend a lot of time in the space, investing in a customized, professionally installed garage door screen can help transform the area into a new hub for your household.

If your door has interchangeable inserts, you’ll likely want to swap the glass out for a screen during the summer months. The process to do so will vary by door, but you’ll follow these general steps: First, use a flathead screwdriver to pop out the retainer strips—the plastic strips running down both long (and sometimes all four) sides of the door. Then gently pull them out by hand. Carefully remove the glass insert from the door and replace it with the screen. Finally, push the plastic retainer strips back into place, working from top to bottom.

You can add any type of window to a brick house, so long as the window has proper support. Windows with wider openings and windows in brick walls will need a lintel to support the extra weight above the window frame. A lintel is a support beam that distributes the weight from above evenly around the window.

If you’re not keen on using a traditional doggie door, there are some alternatives. One popular option is a solid, insulated door that you can lock when you’re out of the home for added security. You can also opt for a doggie screen, which you can lift and lower to allow your pooch access to the outdoors. These are a bit more convenient to use than a regular exterior door, although security could be an issue. You can also install a screen door with a small opening for your pup to prevent bugs from coming inside as your dog exits.

There are a number of ways to secure windows. You can add motion detectors or window sensors to detect movement and impact or change the window locks to make them stronger. Some of the ways you can secure windows are much like how you secure a home: closing the curtains at night and setting up security cameras outside so you can monitor your property even in your absence.
