You're not alone. In fact, at first I thought their sites were standard Wordpress templates. I was kind of surprised they actually built them by hand. They both consist solely of what I would consider standard elements and layouts.

I am pretty certain that the Kintek website is a Wordpress site built using the Roots Starter Theme.

Based on the fact they use:

* Make use of both the Yoast SEO and Gravity Forms plugins, which are well known Wordpress plugins.

* Twitter Bootstrap

* Have an /assets/ folder which most likely rewrites to /wp-content/themes/themename/assets/

* Have a /plugins/ folder which most likely rewrites to /wp-content/plugins/
