Your attic is the biggest source of heat gain and energy loss in most Mount Pleasant homes. Getting it properly insulated and air sealed makes your AC work less and keeps every room in the house at a consistent temperature.
Attic insulation in Mount Pleasant, SC acts as a thermal barrier between your living space and the intense summer heat above, slowing heat transfer so your air conditioner runs less. Most jobs in a standard home are completed in a single day by a two-person crew.
The challenge in this area is that many homes were built before modern energy standards took effect, and decades of coastal heat and humidity cause insulation to settle and compress. If your home was built before the mid-2000s and has never had an attic assessment, there is a good chance the insulation is working below its original rating - and costing you money every month during the long cooling season.
Attic insulation works best when combined with proper air sealing, which is why we pair the two on most jobs. You can also learn more about blown-in insulation, the most common material used in existing attics across the Charleston metro area, if you want to understand the options before we visit.
If your electricity bill has crept up year over year - especially during the long Mount Pleasant cooling season - your attic insulation may be the culprit. When insulation thins out or settles over time, your air conditioner has to run longer to keep up, and that difference shows up on your bill every month from April through October.
If your upstairs bedrooms or rooms directly below the attic feel stuffy and warm even when the AC is running, that is a classic sign that heat is pushing through from above. In Mount Pleasant summers, a poorly insulated attic can make the top floor of a home feel like a different climate zone compared to the first floor.
Look into your attic with a flashlight. If you can clearly see the wooden joists running across the attic floor, your insulation has settled too low or was never installed to the right depth. Properly insulated attics should have enough material that those boards are covered and hard to see from above.
Homes built in Mount Pleasant before the mid-2000s were insulated to standards that are now considered well below what is needed. Insulation also compresses and loses effectiveness over time, especially in humid coastal conditions. If you have never had it looked at, there is a reasonable chance you are losing money every month.
Complete Mount Pleasant Insulation installs blown-in insulation, batt insulation, and spray foam in attics across Mount Pleasant and the surrounding area. Blown-in is the most common choice for existing homes because it fills irregular spaces and settles evenly across the attic floor without tearing out ceilings. Before any new material goes in, we seal the gaps and cracks around light fixtures, pipes, and wall tops - a step that most contractors skip but that makes a significant difference in how well the insulation performs.
For attics with specific air sealing needs, we also offer dedicated attic air sealing as a standalone service. This is especially useful in older homes where the attic floor has gaps around dozens of penetrations that have never been addressed. Both services are often done in the same visit for maximum effectiveness.
Loose-fill material pumped through a hose - the best option for filling existing attics evenly without tearing out finished ceilings.
Pre-cut blanket rolls suited for attics with regular, open framing - a cost-effective choice in new construction or full attic renovations.
Applied to the underside of the roof deck to create a sealed attic envelope - an upgrade option for homes that need moisture control alongside insulation.
Sealing gaps around penetrations in the attic floor before insulation is added - the step that determines how well any insulation type performs over time.
Mount Pleasant sits in a hot, humid climate zone where summer temperatures regularly push into the low 90s and attics can reach 130 to 150 degrees on a summer afternoon. Any gaps or thin spots in your insulation translate directly into a harder-working air conditioner and higher monthly bills. Getting the insulation right is not a comfort upgrade here - it is a basic necessity for keeping energy costs manageable during a cooling season that runs most of the year.
The humidity here also creates a real risk of moisture damage in the attic if the work is not done in the right order. Homeowners in Goose Creek and Summerville face similar conditions. Before new insulation is added, the attic needs to be checked for moisture and properly air sealed - otherwise warm indoor air rises into the attic and creates condensation that leads to mold. A contractor who skips that step is setting you up for a bigger problem later.
Call or submit a request and we will ask a few basic questions - your home's age, square footage, and what is prompting you to call. We respond within 1 business day and schedule a free in-home assessment rather than guessing over the phone.
We visit your attic and check how much insulation is already there, look for gaps around pipes and light fixtures, and check ventilation. This usually takes 30 to 45 minutes and there is no cost. You will get a written estimate explaining what we found and what we recommend.
Clear the path to your attic hatch and plan for some noise from the blowing equipment for a few hours. The crew works almost entirely in the attic - your daily routine is barely affected. Most Mount Pleasant attic jobs are finished in a single day.
Before leaving we walk you through what was done - ideally showing you photos from inside the attic - and confirm the depth and coverage. You should notice your home feeling more comfortable within a few days and see the payoff on your next electricity bill.

We have been working in Mount Pleasant and the surrounding Charleston metro since 2016. We know the neighborhoods, the housing stock, and the specific climate conditions that affect how insulation performs here - and we bring that knowledge to every estimate.
We seal gaps and cracks in the attic floor before adding any insulation. Many contractors skip this step because it takes time, but it is the difference between insulation that performs well for years and insulation that underperforms because warm humid air is still getting through the floor. The ENERGY STAR guidelines recommend it as a required step, and we treat it that way.
Every estimate is free, on-site, and presented in writing. We explain what we found in your attic, what we recommend, and why - not just a number on a slip of paper. You will know exactly what the work includes and what it costs before you commit to anything.
Attic insulation is one of the highest-return upgrades most Mount Pleasant homeowners can make. Doing it right means the right material, the right depth, and the right prep work beforehand - and that is the standard we hold ourselves to on every job.
Loose-fill blown-in insulation that reaches every corner of an attic - a popular upgrade for Mount Pleasant homes built before 2005.
