Heat and moisture rising through your floors cost you money every month. We seal and insulate the space under your Key West home so your AC keeps up and your floors stay comfortable.
Basement insulation in Key West means insulating the crawl space or under-floor area beneath your home, sealing heat and moisture out so your AC runs less and your floors stay comfortable, with most jobs completed in one to two days.
Most homes on the island don't have a traditional basement - they sit on piers or shallow crawl spaces just above ground level. Without proper insulation in that space, heat and humidity rise through your floors all day long, forcing your air conditioner to work harder than it should. If you've noticed warm floors, high cooling bills, or a musty smell near floor level, the crawl space is usually where the problem starts.
We pair this work with closed-cell foam insulation where conditions call for it, and we also install vapor barriers as part of the job when your crawl space needs that extra moisture protection.
In Key West's climate, heat and moisture rise from the ground constantly. If your floors feel noticeably warm or slightly damp underfoot even with the AC on, the space beneath them likely has little or no protection. This is one of the most common complaints in older elevated homes on the island.
When the space under your home is uninsulated, your air conditioner fights a losing battle against heat rising through the floor. If certain rooms never reach a comfortable temperature no matter what you set the thermostat to, under-floor insulation is one of the first things worth checking.
A persistent musty odor - especially in rooms closest to the ground - often points to moisture problems in the crawl space below. In Key West's humidity, wet or deteriorating insulation can become a source of mold and mildew. That smell is your first warning sign - the longer it sits, the more it costs to fix.
If you can peek under your home and see insulation hanging down, torn away, or simply missing in sections, it is no longer doing its job. Pest activity - common in South Florida - can dislodge or damage insulation over time. What you can see with a flashlight tells you a lot about the state of your under-floor protection.
Every crawl space is different, and we match the material and approach to what your home actually needs. For homes with significant moisture exposure, we apply closed-cell foam insulation directly to the underside of the floor or crawl space walls - it seals air gaps completely and resists moisture better than any other option in this climate. For homes that need a complete under-floor solution, we also cover crawl space insulation as part of the same visit.
When old or damaged insulation is in the way, we take care of removal before the new material goes in. Many older Key West homes have deteriorated original insulation that needs to come out first - skipping that step leads to poor results. We also add a vapor barrier when the ground conditions call for it, cutting off the moisture pathway at the source so the new insulation performs the way it should for years to come.
Best for homes with high moisture exposure or significant air gaps in the under-floor structure.
A durable option for homes where spray foam equipment access is limited by tight crawl space clearance.
Added alongside insulation when ground moisture is actively rising into the crawl space - common in older Key West homes.
For homes where deteriorated, moldy, or pest-damaged material needs to come out before new insulation can go in.
Key West has no true below-ground basements - the island sits only a few feet above sea level, so the work here always happens in crawl spaces and under elevated structures. That distinction matters because Key West's tropical climate creates conditions that simply don't exist in most of the country. Average humidity stays above 75 percent year-round, and ground moisture in crawl spaces is a constant problem. Materials that work fine in drier climates - like standard fiberglass batts - absorb moisture, sag, and grow mold in this environment. We specify moisture-resistant materials because that's what the conditions here actually demand.
A large share of Key West's housing stock dates from the early-to-mid 20th century, and many of those homes were built with little or no under-floor insulation. Homeowners in Stock Island and Big Coppitt Key often discover they're living with original material that has long since degraded in the salt air and heat. We also account for hurricane preparedness in everything we do - crawl spaces in vented flood-zone construction need an approach that doesn't trap moisture or create new problems after a storm.
When you call or message us, we'll ask a few quick questions about your home - its age, any comfort issues you've noticed, and whether you know what's currently under your floors. We respond within one business day and can typically schedule an initial visit within a few days.
A contractor will inspect the space beneath your home - checking what's there now, looking for moisture or mold, and measuring the area. You'll get a written estimate before any work begins, including whether removal of old material is needed first.
Clear a path to the crawl space access point and keep pets away from the work area. We handle everything else. Spray foam jobs produce some odor while the material cures, but it dissipates within a few hours and the foam is fully stable once dry.
A professional crew leaves the site clean - old insulation is bagged and hauled away, the crawl space access is closed back up properly. Before we leave, we walk you through what was done and can show you photos taken inside the crawl space during the job.
No pressure, no obligation. We'll assess your crawl space, tell you exactly what we'd recommend and why, and give you a written quote. One business day response guaranteed.
(645) 300-7168Most of the homes we insulate in Key West are elevated Conch-style structures or pier-and-beam homes with tight, low-clearance crawl spaces. We bring the right equipment and know how to work safely in those conditions - not every insulation contractor does.
We treat moisture management as part of the insulation job, not an afterthought. That means specifying materials that hold up in tropical conditions and recommending a vapor barrier when the ground conditions require it. The wrong material here fails fast - we don't take that risk.
We're licensed through the Florida DBPR and we pull the required permits before work begins. Permitted work gets independently inspected - that's protection for you, not just paperwork for us.
Vented crawl spaces built for flood zones need an insulation approach that accounts for how water moves through them during a storm. We know the difference and design accordingly - so the work we do holds up after whatever the next season brings.
We document every job with photos taken inside the crawl space so you can see exactly what was done - even in areas you can't easily access yourself. That transparency matters most when the work is out of sight.
The highest-performing option for humid, hurricane-prone environments - seals air gaps and blocks moisture in one step.
