Signs A Patio Door Needs Replaced

3 minute read


On average, sliding patio doors last 20 years. However, this average lifespan assumes normal wear and tear conditions. The lifespan also assumes the doors have not been repeatedly exposed to harsh conditions. Unless a homeowner has been the sole owner of the property or has had the doors installed, it can be difficult to determine these factors. Fortunately, we can help homeowners recognize the telltale signs that it is time to replace a home’s patio doors.

Top Signs

The top signs we can use to determine whether a home needs replacement patio doors include:

  • The door functions poorly or is broken
  • Poor energy efficiency, including drafts and condensation on the inside of the glass
  • An appearance that no longer fits the desired look of the home

As property owners, we can fall into the trap of complacency if a door starts sticking, not working properly, or not shutting all the way. Doors that seem to be in constant need of repair and are not working the way they should could become a safety hazard. Doors that do not shut all the way and do not lock properly can increase the chance that someone can break in or enter the home. Sliding glass doors, for instance, should be replaced when the rollers become difficult to use or the doors no longer stay on the track.

Concerns about energy efficiency are a sign it is time to invest in replacement patio doors. If the doors are more than ten years, there’s a high chance that they are not as efficient as the latest options. Telltale signs such as moisture on the inside of the glass during cooler months or drafts means the doors are no longer keeping air in the home. We can install doors that meet the latest energy efficient standards and ratings. Doors that meet the latest standards not only provide improved insulation but help homeowners save on utility bills in the summer and winter.

The appearance of the home’s current sliding patio doors may not fit with the overall look of the room. A previous owner could have updated the windows and the doors no longer match. It is also possible the look of the room has changed, more light or a different look is desired. Installing French doors is a popular way to update a room with a more sophisticated look and increase resale value.

Replacement Costs

If one or more of the signs are present, it can be natural to worry about financing. While an owner should get at least two or three quotes from different vendors, choose one that offers a warranty and zero interest payment options. At Advanced Window Products, we offer a double lifetime warranty, zero down and zero percent financing for 60 months. We also offer a 100% satisfaction guarantee.

Putting off the decision to replace a home’s doors can result in higher long-term costs. If doors are no longer functioning properly, are showing signs of poor energy efficiency, or no longer fit the home’s look, don’t put it off any longer. We’re happy to help with replacement quotes and affordable payment options.

We recently had new windows installed and the difference has honestly been incredible. The first thing we noticed was the noise reduction. We live close to two major roads, and traffic noise used to wake me up constantly throughout the night. Since installing these windows, it’s amazingly quiet inside the house — I can barely hear anything outside now. That alone has been life-changing for us.Beyond the sound reduction, the windows completely upgraded the look of our home. They feel modern, high-quality, and extremely well made. The value for the price was excellent, especially considering how much they improved both comfort and appearance.We’ve also noticed a huge difference in temperature control throughout the house. Rooms stay much more comfortable, and the home feels far more energy efficient overall. The house maintains temperature better and feels less drafty no matter the time of day.Overall, we could not be happier with the investment. The combination of appearance, quality, energy efficiency, and especially the noise reduction exceeded our expectations. - 5/12/2026

If you are on the fence about using Advanced Windows, go ahead and take the leap. The entire experience was seamless and professional. Mason was our initial sales contact. He was never pushy but he simply gave us the facts and let us ask the questions and do the research. He gave us a list of nearby addresses of customers. We drove by each one and even rang doorbells. Yes we sure did! All were happy with their choice and the windows are beautiful. They use argon gas in between panes and you really notice how the transfer of heat is stopped in the Arizona sun. Truly a game changer. The windows are manufactured by the same company used by the higher end companies but at a much more affordable cost. Life time warranty to boot.The installation team was outstanding. I asked for their names because they deserve a shout out Francisco,Mario,Julio,Saul and Martin. If you can, ask for them by name. They were professional, knowledgeable,detail oriented,courteous and clean. No mess. The company got our windows done in 1 day which is mostly due to this team’s hard work and due diligence. I will recommend this company to anyone! The windows work effortlessly and really add to the appearance of our home. I have no doubt the was one of the best decisions we have made to add value to our home. - 5/11/2026

My windows are beautiful that I got from Advanced Windows. Dallin helped me order my windows and he was amazing to work with. So professional and helpful. Gasson and his crew are second to none. You definitely want them when it comes to installation. They are perfectionists and will make sure everything is the exact way you want your windows to be. Grace in the office is kind and on top of scheduling all of the appointments. I would definitely recommend Advanced Windows if you are thinking about getting new windows. - 5/11/2026

From the first meeting where we discussed the product and price to the installation the whole Advanced Windows team was excellent. The price was great, the product is great, and the fact that they manufacture locally means I'm not worried about them being able to make good on any warranty issues. I recommend them wholeheartedly and would use them again. - 5/08/2026

It was great working with Advanced Window Products. The 0% finance and over all cost of our 15 windows was the lowest price out of 4 other companies.Installation was fast and easy only taking 2 days. We had a few issues and the team came back is fixed them in less than 1 hour. All our windows work great and we can feel the difference already.Looking forward to see how well the windows perform in summer - 4/16/2026
