Our Work






What questions should I ask
a residential general contractor when I want to upgrade my space?
General contractors often juggle multiple projects and rotate teams between them. Make sure the crew coming to your home is not only familiar with your project, but with your family and your home. KCS Building Group assigns a dedicated team to work on your project from start to finish. Our teams take great pride in their work and adhere to our strict code of conduct.
Your residential general contractor should have an end-of-day cleanup policy that covers tool storage, waste disposal, debris removal, dust cleanup, etc. KCS Building Group clears the clutter every day, period.
Your residential general contractor should provide you with regular work hours so you can plan around construction. Discuss parking, restroom use, pet security, and who will be home during construction hours. KCS Building Group respects your space, your family, and your neighborhood’s schedules and preferences.
No two additions or upgrades are the same, but your contractor shouldn’t be starting from scratch. Make sure your residential general contractor is skilled and experienced with projects like yours so you get the results you want.
