Insulation & Sealing

Keep the Cool In and the Heat Out

Air Sealing

Stop the leaks you can’t see.

Every home has tiny gaps and cracks where air slips through – around windows, doors, pipes, recessed lights, and attic hatches. These leaks may be small, but together they can add up to the equivalent of leaving a window wide open all year.

We carefully test and seal these problem areas with proven materials like caulk and weatherstripping, so your home stays consistently comfortable without drafts, hot spots, or wasted energy.

Duct Sealing

Make sure your air actually reaches your rooms.

Your ducts are the hidden highways that deliver cooled or heated air throughout your home. But in many houses, those ducts are leaking 20–30% of that conditioned air into attics, crawlspaces, or walls. That’s money wasted — and comfort lost.

Our team seals leaky joints and insulates ductwork so the air you pay for actually makes it to your vents. The result is a system that runs more efficiently, rooms that feel more even, and bills that finally make sense.

Attic Insulation

Your attic shouldn’t be an oven.

In Louisiana, the attic is one of the biggest sources of energy loss. Without proper insulation, the summer heat radiates down into your home, forcing your AC to work harder than ever.

We install modern attic insulation to create a thermal barrier between your living space and the blazing attic above. Paired with air sealing, this upgrade dramatically improves comfort and can cut cooling costs for years to come.

Here's What Our Insulation & Sealing Customers Have to Say:

Jim Clarke and his Asyndant Energy team did a fantastic job full circle in replacing my attic insulation. I started with a pest issue in my attic, which I was working on and came into contact with Asyndant Energy and Jim Clarke. I had gotten several quotes on replacing my insulation in the home and Jim… working with Cleco…was the deal of the century! His professionalism along with his entire team made this very difficult situation seamless and efficient. His team was very through in making sure that my entire AC system was sealed throughout the entire house, plus any ducts that needed work were fixed. I was very impressed with all the testing they did on my AC system to make sure it was up the par! I could not have been more impressed with the team and their work ethics…they really did go above and beyond!

Frequently Asked Questions

How does insulation work?

Insulation helps maintain your home’s temperature by reducing heat flow. It keeps your spaces cooler in summer and warmer in winter, ultimately saving energy and improving comfort. Each type of insulation has its benefits, and the right choice depends on your home’s needs.

Why is air sealing and duct sealing important

Sealing gaps and cracks around your home helps prevent air leaks, which can lead to energy waste. Proper sealing increases efficiency in heating and cooling systems, keeping your energy bills lower and your home comfortable.

What are the signs of poor insulation?

Signs of inadequate insulation can include high energy bills, fluctuating indoor temperatures, being able to see your ceiling joists, and cold drafts in winter. Additionally, walls and ceilings may feel unusually cold or hot, indicating a lack of effective insulation.
