About Keystone Carpentry LLC

I enjoy working directly with my customers and try to exceed their expectations. I strive for perfection with honesty and integrity. I don't cut corners with cheap materials or work, but instead go the extra mile to achieve good results. I started my carpentry business in 2018 after working several years for a general contracting company. In the big company model a lot of smaller jobs get overlooked. So, I started out on my own in order to fill that need and to have more flexibility and earning potential.

Mark was very professional! He under promised and over delivered!! What more can you ask!!! Interviewed many people for the job and Mark came out on top in every area! Thank you Mark! You will be the first one we call for all our future jobs!

Very quick to reach out about my inquiry. Had the job scheduled within a couple days and completed within the week. Super friendly and great work.

I called on a Friday and had new doors Monday. I have no complaints and would 100% use him again for further projects. Very nice guy as well.

Did a great job on the front porch, very happen with the work. Will be hiring again for my back deck.

Mark completed our deck a couple of years ago. He did a fantastic job! Our deck has held up perfectly and we are very happy with it even years later. Mark went the extra mile and added finishing touches such as rounding the ends of the deck boards so that we didn't have any sharp edges on the stairs.

Mark did a fantastic job replacing several interior and one exterior door. He was thorough and took his time to ensure the job was done correctly. He was also very mindful of minimizing mess and was overall very helpful and respectful of our home and needs (dog and children present). We would absolutely hire Mark again in the future - he provided high quality work for a reasonable price. I have no doubt that he did a better job than what we would have paid a bigger company to do.
