About K and M Custom Concrete LLC
Dedicated to quality workmanship, integrity, and personal customer communication in Montgomery, TX and surrounding communities.
Restoring & Transforming Texas Concrete Since 2019
We started K and M Custom Concrete LLC in 2019 with a commitment to quality workmanship, attention to detail, integrity, and customer satisfaction.
We specialize primarily in giving existing concrete new life rather than taking on general full-pour concrete projects. When you hire us, you work directly with us—from evaluating the surface and discussing your options to completing the project with careful attention to detail.
The K&M Promise
"Whether we're restoring a pool deck, resurfacing a porch step, or putting an industrial polyaspartic coating in your garage, we treat your property with respect, communicate every step of the way, and don't leave until you're completely satisfied."

Real Customer Feedback
Concrete Finishing, Overlays & Coloring Application
"We had 2 concrete/flagstone walkways put in by another company whom we dismissed before the sidewalks were stained. We consulted with 2 companies recommended by Home Advisor, neither of whom responded with a quote or reply in over 3 weeks. Keith responded the day of the post, set up an appointment for Monday. He understood exactly the color we wanted, explained how it would be done. WE received the estimate the next day, accepted his offer and the project was done on Friday! He and his wife worked together in the sweltering heat and got it all done - beautifully! Would strongly recommend interested clients to please call them."

Concrete Floor Coating Apply
"This project included leveling, covering and texturing the original pebble stone surface and two smooth surface pads that made up my front and side concrete porch. Keith and his team worked around weather delays and even had to do some rework caused by weather damage. He did the right things to get the job done correctly and to a high level of quality. The team was always on site when they said they would be and worked diligently. Keith worked with me, keeping me informed of progress and setbacks and made adjustments without issue. A very professional individual and team. Plan to have K&M Custom Concrete do more work on the driveway later this summer."

Concrete Flatwork Repair & Resurface
"I had all my cement floors in my home grinded, repaired, sanded and color applied. Keith is very professional, punctual, patient and very kind. His team were also very hardworking and trustworthy. Although the job did take a bit longer than expected, my floors came out excellent. I would recommend them and would hire them again!!"
