"Rick and Cindy, the owners of Colorado Outdoor Life, are amazingly friendly, knowledgeable and ethical business professionals. I really enjoyed working with them and Victor, the Lead of the construction crew. Victor is so friendly and easy to talk with - the whole team was just great! I had 31+ year old window wells that were a mess - rusty, holes in the sides, water was beginning to seep into the side walls. In 3 days, Victor and his team dug out the old and installed the new window wells - not window covers - window wells! That is Extremely hard work and the team was just wonderful.

"Oswald and his crew were fast, efficient and the house looks amazing! What an improvement from what we had before.

After siding was installed, we used Bermudez Paint, and they arrived the next day to start their project. They were done 3 days later, thanks to rain delays. I highly recommend Bermudez Paint as well. Their team was also amazing, fast, and incredibly polite."

FAQs for window and door contracting projects in Littleton, CO
Door installation usually takes three and four hours, including removing the old door and frame, fitting the new door and frame in place, shimming it to make sure it’s perfectly level, and making adjustments to the hinges and locking mechanisms to ensure proper functionality. A door-hanging professional can replace an interior door in between one and two hours. Door installation will take significantly longer if your installer needs to create a wall opening, and it can take less time if the existing door frame remains.
If you have a problem with your window, such as broken glass, minor leaks, or a problem with your window being stuck, repairing the broken part might be a cheaper option than replacing the entire window. However, if you have a deteriorating window frame or major leaks, buying a new window will be the better long-term solution.
The average cost to install a door is around $1,100, but you could pay anywhere from $150 for a hollow-core interior door installation up to $2,000 or a high-end exterior door installation. There are a few cost factors to consider to get an accurate price, including whether your wall opening exists, the type of door, the quality and security of the door, whether you need to replace the frame, and the door size. You can expect to pay $150 to $700 for a standard 36-by-80-inch door and between $400 and $1,600 for an 80-by-48-inch door.
Window replacement costs between $180 and $410 per window, or an average of $280 per window. However, your specific replacement job could cost as little as $100 or as much as $750. Factors such as frame material, the number of windows you need, and the type of glass you order all impact the overall cost. For example, simple double-glazed windows will cost $3 to $6 per square foot, but the stronger tempered glass ranges from $12 to $14 per square foot.
It’s possible to install a door yourself if the wall opening already exists, but the work is rather complicated, and a professional installation is usually well worth the investment. For your door to work and close properly, you’ll need to shim and level the door frame in your wall perfectly, which can be difficult. Additionally, we recommend you always hire a professional door installer to place an exterior door, as mistakes during the installation process can lead to poor security for your home.
