Florence Insulation Company is an insulation contractor serving Myrtle Beach, SC with spray foam insulation, attic insulation, and crawl space services for homeowners and vacation property owners along the Grand Strand. We reply to all estimate requests within one business day and provide written quotes with no obligation.
Myrtle Beach's salt air and year-round coastal humidity wear down traditional insulation faster than most property owners expect - especially in homes built in the 1980s and 1990s that have had the same attic insulation for decades. Our spray foam insulation bonds directly to surfaces, resists moisture, and does not sag or settle over time the way loose-fill or batt insulation can in a coastal environment.
Most homes in Myrtle Beach are slab-on-grade construction, which means the attic is the primary thermal barrier between the living space and the outdoors. With average summer highs in the upper 80s and humidity that makes the heat feel worse, an under-insulated attic forces air conditioners to work continuously during the months when electric bills are already at their peak. Many homes built in the 1980s and 1990s are now at the age where original attic insulation has settled and compressed well below effective levels.
Myrtle Beach properties - especially those that sit empty for months as vacation rentals - are vulnerable to air infiltration that slowly but steadily lets humid, salt-laden coastal air into the building envelope. Air sealing around attic penetrations, wall-to-ceiling junctions, and mechanical chases is the step that converts a basic insulation upgrade into a genuine performance improvement. We identify and seal those pathways before insulation goes in so your investment holds up through the humid Grand Strand summers.
Not all Myrtle Beach homes are slab-on-grade - older beach cottages and some homes in lower-lying neighborhoods have crawl space foundations. In these homes, a properly installed vapor barrier stops ground moisture from rising into the floor structure, a real concern given Myrtle Beach's flat terrain and the drainage problems common in parts of Horry County that sit in or near FEMA flood zones.
Closed-cell spray foam adds a moisture barrier along with insulation, which is particularly valuable for Myrtle Beach properties where salt air, high humidity, and the occasional tropical storm push moisture into every gap and crack. It is especially well-suited for coastal homes where you want a product that stays effective over the long term rather than requiring periodic replacement as humidity cycles wear it down.
Myrtle Beach sits directly on the Atlantic coast, and the environment here is harder on homes than most of the country. Salt air accelerates corrosion and material degradation throughout a building. The combination of intense summer heat, high humidity, and salt-laden air means insulation and building materials that would last 30 years inland may need attention in 15 to 20 years here. Most of Myrtle Beach's housing stock was built between the 1980s and the 2000s as the Grand Strand grew into one of the fastest-growing areas in South Carolina - and many of those homes are now at the age where original attic insulation has settled, compressed, or absorbed enough ambient moisture to be performing well below its original rating.
The high share of vacation homes and rental properties along the Grand Strand creates a specific challenge: deferred maintenance. When a property sits empty for months at a time, small problems - a gap in the building envelope, thin attic insulation, a stucco crack letting moisture into wall cavities - compound without anyone noticing. Owners who live out of state often come back to find issues that have been building all season. Myrtle Beach also sits in the path of Atlantic hurricanes, and even storms that do not make direct landfall can bring damaging winds and heavy rain that expose weaknesses in an under-maintained building envelope. A contractor who understands the Grand Strand's coastal conditions and the specific maintenance needs of vacation properties brings more to the job than just materials and labor.
Our crew works throughout the Myrtle Beach area and pulls permits through Horry County Building Services when projects require inspection. We encounter the full range of Myrtle Beach property types - older beach cottages closer to the oceanfront with original 1970s construction, 1980s and 1990s vinyl-sided single-family homes in established neighborhoods, and the newer production-built subdivisions in Carolina Forest and areas off Highway 17 that have appeared since the 2000s.
The Grand Strand is a 60-mile stretch of coastline that runs through Myrtle Beach and the surrounding communities, and the homes along it face insulation challenges you simply do not see 50 miles inland. Whether your property is a few blocks from the Myrtle Beach Boardwalk or out in a newer neighborhood off Highway 501, we have worked on homes throughout the area. We also serve homeowners in nearby Moncks Corner and Conway, where the low-lying coastal terrain creates many of the same moisture and humidity challenges we see along the Grand Strand.
We reply to all calls and contact form submissions within one business day. For vacation property owners calling from out of state, we can discuss the property remotely first and schedule an assessment around your availability or a property manager's access.
We inspect the attic, any crawl space areas, and the building envelope and provide a written estimate with a full breakdown of work and materials. The assessment is free. For out-of-town owners, we can send photos of what we find along with our written recommendation so you have a clear picture before approving work.
Our crew arrives with all equipment and completes the work in one to two days. If spray foam is used, the treated area needs to air out for 24 hours before occupants return - we will confirm the schedule and return time with you in advance and coordinate with your property manager if needed.
After installation, we document the completed work with photos and written records of materials used. This is especially important for vacation property owners who need confirmation without being on-site. We also handle final permit inspection coordination if one was required.
We reply within one business day, provide free written estimates, and work with out-of-town owners who need a contractor they can trust to handle things in Myrtle Beach without requiring your presence. Call now or fill out the form.
(854) 204-1707Myrtle Beach is one of the most visited resort cities on the East Coast, drawing millions of visitors per year to its oceanfront hotels, restaurants, and attractions along the Grand Strand. The full-time resident population is around 35,000, but the broader Horry County metro has grown to over 400,000 people and has been one of the fastest-growing regions in South Carolina for two decades. The housing stock reflects that growth: older beach cottages from the mid-20th century sit close to the oceanfront, while 1980s and 1990s vinyl-sided single-family homes make up the bulk of residential neighborhoods inland. Newer subdivisions in areas like Carolina Forest and near The Market Common have added a large number of production-built homes since the early 2000s.
A significant share of Myrtle Beach's housing units are vacation properties, short-term rentals, or condominiums - many owned by people who live out of state and rely on local contractors to keep their properties maintained year-round. Condos near the oceanfront often need interior insulation work since HOAs handle building exteriors. We serve property owners across the full range of Myrtle Beach home types, and also work in nearby Moncks Corner and Conway, where the flat coastal terrain and high humidity create many of the same building performance challenges as Myrtle Beach.
