DTK Windows & Doors LLC.

DTK Windows & Doors LLC operates in Humble, TX and is run by Derek. The company handles window replacements, door installations including prehung units, patio doors, front doors, French doors, and related work such as siding installation and leak repairs around windows. Derek often works with a small team that includes his son on some projects, focusing on both single-item fixes and larger jobs like replacing ten windows at once or outfitting an entire home exterior.

Customers describe Derek diagnosing leaks near upstairs windows that multiple prior contractors failed to identify over months, then completing the window replacement the same day. Other jobs include installing a prehung door after big-box retailers stopped responding, moving a patio door during a ten-window project, replacing doors and windows in a historic 1877 home despite uneven walls and floors, and adding LP smart siding alongside new windows. Reviewers note that Derek explained options without pressure during consultations, selected designs to match existing expectations, and completed work on difficult replacements while maintaining quality.

Derek and his crew arrive when promised, often first thing in the morning, finish ahead of schedule, and clean up thoroughly including sweeping driveways and using drop cloths to limit mess inside and out. They communicate throughout each step, from order timing to scheduling, remain available for questions, and treat homes and families with respect by avoiding unnecessary disruption. Service covers both small repairs and full exterior updates, with reviewers highlighting the same approach on jobs ranging from one door to multiple windows and siding.

“Derek and his team were wonderful. They were on time, and worked quickly and efficiently. I had a prehung door that I bought from Home Depot so I needed his services to install it as I could not get Home Depot to respond to my request for an installation. I googled door installation services and chose Derek based on his rating. I called and to my pleasant surprise he said he would be out first thing in the morning. I had been trying with Home Depot for weeks! Thank you Derek for a job well done! I will definitely be calling you as soon as my back door comes in!”

“Derek was very professional. The quality of his craftsmanship was great! He replaced 10 windows and moved a patio door I would highly recommend Derek for small and big jobs. He has a no nonsense approach that is not offered by many contractors today. 5 star triple A rate!!!”

“We worked with Derek from start to finish on our front door replacement. Derek and his crew were knowledgeable, professional, courteous, hard-working, and efficient. The door is not only beautiful but of the highest quality and perfectly installed. We definitely will use DTK on our upcoming window replacement project!”

“I can't say enough about Derek and his team; from start to finish the process has been fantastic. When Derek came out for our consultation his intention was on getting us informed on windows and all of the options instead of pressuring us into a purchase. He was extremely helpful in aiding us with a design that accented our expectations; we chose DTK windows and doors because of their amazing customer service, and unbelievable warranty. Derek was extremely courteous and professional; and has always been available to answer any questions that we’ve had. We look forward to future projects.”

“We highly recommend Derek and DTK Windows and Doors! Prior to contacting Derek, we had four different folks look at a leak we had near an upstairs window over the course of three months – all of whom could not figure out the issue. Derek came and looked at the issue and was able to figure out the problem and provided a solution the very same day. He is extremely knowledgeable and shared with us details of the problem and next steps to get the issue fixed which included replacing our window. Derek was very professional, honest and communicated with us throughout the process from start to finish which included when the window was ordered, how long it would take to come in and when to schedule a time to replace it in our home. After Derek and his team replaced our window, he followed up with us once we had our next rainstorm to ensure we did not have any leaks again, and of course we did not – problem solved! We are thankful for Derek’s due diligence and resolving the issue quickly and in a timely manner.”

“Derek and his son installed all new windows and new LP smart siding on my home. They up when they said they would, they had the job done ahead of schedule and did a great job of cleaning up after themselves. I would HIGHLY RECOMMEND Derek for project from one window being replace to the entire outside of the home being done!”

“Derek & team were very professional. They replaced several windows including a large, heavy picture window. They took the time to use drop-cloths inside and outside of the house to contain the mess. They cleaned up after themselves and didn't purposely aggravate the dogs (not all contractors can say this). The windows are all high quality & greatly reduced the "outside noise" from being heard. They also custom cut the trim for the window interiors and painted the exterior trim. Highly recommend”

“Derek and his team were very respectful of our home and our family. They took time to make sure every detail was correct with two difficult to replace windows. With clean up they were very thoughtful, going as far as to sweep not only their mess in the driveway, but dirt we already had there. Highly recommend this company.”

“Derek replaced the front door and three French doors in our home. It was a pleasure to deal with him. He communicated clearly, showed up when he said he would, installed the doors professionally, and cleaned everything up beautifully. I highly recommend him!”

“Derek came by our house to look at an issue we were having in the front of the house that we'd tried endlessly to get the builder to fixed, but they couldn't figure out the problem and refused to help. Derek was able to diagnose the issue very quickly, and within a couple of days had the problem that had plagued us for a few years fixed. We highly recommend giving this company a call!”

“Derek replaced windows and doors in our 1877 historic house and they look great! Even with uneven walls and floors, the quality of the installation is 5 star!”

“I HIGHLY recommend Derek to anybody! He was a dream to work with. Always communicated everything, showed up on time and cleaned up after himself. He even interacted with out toddler who got to "help" with clean up.”

“Excellent customer service. Got my door to temp shut and will be back to shore it up. I'd recommend him to anyone for any door and window job. He's a class act.”
