Light commercial

Priced for the actual property.

We check each business site and quote a price for the job. We look at the systems, access, parts, permits, and time needed. We explain the price before you agree to work.

The simple ruleCheckmate and King’s Shield are home care plans. Their prices do not apply to business sites.

  1. Service assessment

    We tell you the fee to visit and check the site first. Then we check the system, how to reach it, and what went wrong.

  2. Preventive maintenance

    The price for routine care depends on your systems and how many you have. It also depends on visit times, access, filters, belts, and the checks you agree to.

  3. Repairs and projects

    After we check the site, we give you a written price for the work. We list any parts, permits, rentals, or special tools needed.

  4. After-hours response

    Urgent work at night, on weekends, or on holidays may cost more. Fees may cover travel and extra work hours. We explain the cost before we send a truck.

Owner & CEO Will Hamby, owner and CEO of KnightStone Home Services

Will Hamby

Owner & CEO

For over 30 years, I have worked across Middle Tennessee, from Nashville, Franklin, and Lebanon right home to Cookeville. Over three decades in the trades, I have handled nearly every type of residential, commercial, and industrial job out there, from HVAC, electrical, and plumbing to welding, fabrication, geothermal, pipe fitting, and medical gas.

My philosophy has always been simple: treat people right, charge an honest price, and do the job right the first time. No shortcuts. I have never been in this business to get rich off someone else’s hard-earned savings. When you treat folks fairly and stand behind your work, they remember it, they pass your name along, and the business takes care of itself.

To our military community: a standard 10% discount never felt like quite enough, so KnightStone gives 15% off to our veteran brothers and sisters. It is our small way of giving back to those who served.

With gratitude

Honoring those who served.

Veterans receive 15% off.
