"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."

"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!"

"Juan has done work for us over several years and we keep asking him to do more! He most recently helped patch holes in our drywall and ceiling, He also repaired our attic hatch, replaced the seal at the bottom of our garage door, installed a storm door, and put in a latch to hold our furnace filter in place. Juan does quality work AND is reasonably priced. He gives free estimates and schedules the work in a timely manner! We found a gem many years ago and will continue to hire him for projects!"

Window Door Contractors FAQs, answered by experts

Most window screens in residential homes are designed to be removed from the inside, especially with double-hung, single-hung, and casement styles. That said, some setups require exterior removal. Older homes or custom installs may have exterior clips or brackets, and sunscreens are almost always mounted on the outside. Before removing your window screen, look at how it is held in place.

Most windows last for 15 to 30 years, depending on the frame material and the glass quality, but most will require repairs during that time. Windows gradually lose efficiency, so it’s usually best to have a window repair technician inspect and service your windows every five to 10 years. You should also repair your windows if you experience the following:

  • Leaks

  • Drafts

  • Difficulty opening or closing

  • Sudden increases in heating and cooling bills

  • Outdoor noise becomes more audible

  • Signs of physical damage

To ensure the longevity and smooth functioning of new windows, regular maintenance is essential. This includes cleaning the glass and frames, inspecting seals for leaks or damage, and reapplying caulking as needed. It is also important to lubricate all moving parts and operating mechanisms to ensure they continue to operate smoothly.

Screen doors have a positive ROI because of their safety features. They add protection from debris, critters, and, depending on the material, even heat. However, storm doors are better than screen doors when it comes to overall protection.

By replacing the worn mesh and repairing frames, restoring functionality and appearance.
