K&J did a good job installing our new French patio door . They were very helpful with the choosing of the details to fit what we were looking to include in the design. K&J were very quick to solve any problems that came up, very happy with this company.

Just had new windows installed today by K&J windows. I loved the whole experience. The salesman (Cody) was so knowledgeable about our 1970’s slump block house. The install crew was so great! They were knowledgeable, problem solvers, communicated well, polite, and super detail oriented. They spent the last 4 hours sealing the outside and inside of the windows (then cleaning up completely) after they were installed. Super impressed.

Just replaced our windows with K&J Windows and they have done an awesome job. Very detailed! No upselling of window products. Our previous old windows were inefficient and foggy but the new ones are energy efficient and Chrystal clear. Great job, thanks!

The sales rep Cody was honest and straight forward. The bid was a fraction of the others received for the exact same Milgard windows. The install team completed the job which was all 12 windows and a large 2-panel sliding door that replaced an old 3-panel one in just 1 day. I've looked at all the homes in our 30 year old neighborhood that have had their windows replaced, and the fit and finish on our job met or exceeded any of the ones that I've seen. Any time I have a project completed on our home, I have at least 3-4 contractor bids. If you are looking to get your windows replaced, make sure you include K&J on your list or just go straight to them and don't waste your time.

Yes. Professional window replacement can significantly increase your home’s market value. Buyers often look for energy-efficient windows because they improve comfort, reduce maintenance, and lower energy costs.
In many cases, standard window replacement for the Phoenix projects do not require permits when replacing windows with the same size and style. However, structural changes or resizing windows may require permits. K&J Windows helps homeowners understand local requirements before beginning the project.
Thanks to the mild Arizona climate, Phoenix window replacement can be performed year-round. However, many homeowners prefer spring or fall when temperatures are moderate and installation is even more comfortable.
After your window replacement project, simple maintenance will keep your windows performing well. Regularly clean the glass, inspect seals, and ensure tracks remain free of debris for smooth operation.
