Boca Raton & Palm Beach County
On a July afternoon in Boca Raton, the air in an under-insulated attic sits far above the outdoor temperature, and that heat pushes down through your ceiling all day and half the night. Insulation is the only thing standing between it and the room you are sitting in.
Attic temperatures vary with roof color, ventilation, sun exposure and time of day. We measure yours during the inspection rather than quoting from a chart.
Why South Florida is different
In Boca Raton the enemy is heat coming in, not warmth escaping. That single difference changes what belongs in your attic, how thick it should be, and which products are worth the money.
Palm Beach County sits in Climate Zone 1the hottest classification in the Florida Building Code, shared only with Miami-Dade, Broward, Monroe, Collier, Lee and Hendry counties. Everywhere else in Florida is Zone 2. Zone 1 homes run their air conditioning for most of the year and their heat almost never.
That means the job of your attic insulation is to slow heat moving downward into your living space through the hottest months. It is working against a 130-degree attic for eight or nine months a year, not against a cold snap for six weeks.
Moisture is the second half of the problem, and it is the half most homeowners never hear about. Coastal air carries a heavy moisture load. Where that moist air meets air-conditioned surfaces, you get condensation, and condensation in an attic finds insulation first.
Wet insulation does not insulate. Fiberglass that has absorbed moisture loses a significant part of its rated performance and does not recover on its own. It also compresses, mats down, and becomes a place mold is happy to live. This is why an attic three miles from the beach ages differently than one built to the same specification inland.
The R-value printed on the bag is the value when new and installed correctly. Twenty years of settling, foot traffic from roofers and AC technicians, rodent activity, roof leaks and storm intrusion all subtract from it. An attic that met code the day it passed inspection may be well under that number today, and nothing about it looks obviously wrong from a ladder.
What we do
Loose-fill fiberglass or cellulose blown to an even, measured depth across the attic floor. It flows around wiring, framing and awkward corners that batts cannot cover without gaps, which is why it is the most common choice for existing Boca homes.
Open-cell and closed-cell polyurethane foam, applied to the roof deck or the attic floor depending on the goal. Closed-cell adds structural rigidity and acts as its own moisture barrier. Foam is the most expensive option per square foot and the right answer less often than it is sold.
Pre-cut fiberglass or mineral wool batts for garages, interior walls, floors over open spaces, and additions where the framing bays are clean and accessible. Straightforward, cost-effective, and only as good as the fit, a batt with a gap at the edge loses much of its value.
Vacuum removal of insulation that is wet, compressed, contaminated by rodents, or damaged by a roof leak. Adding new material on top of failed insulation traps the problem underneath it. When removal is warranted we will tell you, and when it is not, we will tell you that too.
Sealing the gaps insulation cannot cover: can-light housings, plumbing and wiring penetrations, the top plate of interior walls, the attic hatch. Florida's own energy guidance is explicit that insulation has to be paired with air sealing and moisture control to do its job.
Reflective foil installed against the underside of the roof deck to turn back radiant heat before it ever reaches the insulation. It addresses a different mechanism than R-value does, which is why the two work together rather than replacing one another.
Your ductwork runs through the hottest part of the house. Air chilled to 55 degrees at the handler arrives warmer than it should if the duct insulation has torn, sagged or come loose at the boots, a common and completely invisible loss.
You do not need to know which of these you need. We measure the depth and condition of what is up there, check for moisture and pest activity, look at the ducts and the sealing, and give you a written scope with the reasoning attached.
The numbers
R-value measures resistance to heat flow. Higher is better, and the scale is not linear, the jump from R-11 to R-30 buys far more than the jump from R-30 to R-49.
| Situation | Ceiling / attic R-value | What it means for you |
|---|---|---|
| Florida code minimum, Climate Zone 1 Palm Beach County included | R-30 | The legal floor for new construction. A floor, not a target. |
| Florida code minimum, Climate Zone 2 Central and North Florida | R-38 | Higher than ours, because those homes also heat in winter. |
| Common in Boca homes built before the 1990s | R-11 to R-19 | Roughly a third to two thirds of today's minimum. |
| Attic that has settled or been walked on for 20 years | Below its original rating | Compressed insulation is thinner insulation. |
| Typical threshold for the FPL ceiling insulation rebate | Under R-8 | If you are here, you have been overpaying for cooling for years. |
Code minimums are from the Florida Building Code, Energy Conservation, 8th Edition (2023). R-value applies to the insulation material itself, drywall and roof decking do not count toward it.
Florida Power & Light runs a Residential Ceiling Insulation Program that pays a flat rebate on qualifying installations. To qualify you generally need an active FPL residential account, whole-house central electric air conditioning and heating, and an existing verified ceiling insulation R-value below R-8.
The catch: FPL requires the work to be performed by a contractor enrolled in their Participating Independent Contractor program. Ask us about your eligibility and we will tell you straight whether that rebate is available on your job, we would rather you hear it from us than find out after the invoice.
FPL sets these terms and can change them, including the rebate amount. We confirm current requirements with FPL before we tell you what your job qualifies for.
Self-assessment
None of these on their own proves the insulation is the problem. Three or more usually means it is worth someone going up there with a tape measure.
A word about savings claims
Every insulation company in South Florida advertises a number, save 30%, save 40%, cut your bill in half. We do not, and it is worth explaining why.
What you actually save depends on how bad the starting point is, how big and how shaded the house is, the age and efficiency of your air handler, the condition of your ducts, what your roof is made of, what colour it is, and how you personally use the thermostat. Two identical houses on the same street produce different numbers.
An attic sitting at R-8 that gets brought up to code properly will produce a difference you can feel and see on the bill. An attic already at R-30 will not, and anybody telling you otherwise is selling you something you do not need.
What we will do is show you the measurement. The depth we found, the R-value it works out to, what code asks for, and what the gap costs you to keep. Then you decide.
How the job runs
We get into the attic, not a look from the hatch. Depth measured in several places, moisture and pest check, ducts and penetrations noted, photos taken so you can see what we saw.
What we found, what we recommend, what it costs, and what happens if you do nothing. Line by line. If part of the job can wait, we will say which part.
Floors and pathways protected, equipment staged outside, removal first where it is needed, then air sealing, then new material to the agreed depth. Depth markers left in place so it can be verified.
Photos of the finished attic, the depth achieved, the material and its rating, and the site left clean. You should be able to check our work without climbing a ladder.
Service area
If you are just outside this list, call and ask. We would rather tell you honestly that you are out of range than send someone an hour each way and price the drive into your job.
Questions
Palm Beach County is in Climate Zone 1, where the Florida Building Code sets a minimum ceiling insulation value of R-30. That is the floor for new construction, not a recommendation to aim at. Florida's own home energy guidance describes R-30 to R-38 as current best practice for attic insulation. If your attic is materially below R-30, bringing it up is usually the single highest-value change available in the house.
Often yes. Topping up dry, clean, undamaged insulation is normal and it is the cheaper path. There are three situations where it is the wrong move: the existing material is wet or has been wet, it is contaminated by rodents, or it is so compressed that adding to it just buries a problem. In those cases the old material comes out first. We will tell you which situation you are in during the inspection, and we have no reason to invent a removal job, it makes the quote bigger and the sale harder.
Sometimes, and less often than it is sold. Closed-cell foam is an excellent product, high R-value per inch, its own moisture barrier, and it adds rigidity to the structure. It is also the most expensive option per square foot by a wide margin. For a typical Boca house with an accessible attic and no moisture problem, properly installed blown-in insulation plus air sealing gets most of the same comfort result for a fraction of the cost. Foam earns its price in specific situations, a sealed attic assembly, tight or irregular framing, ducts you want inside the conditioned envelope. We will tell you which one you have.
A straightforward blown-in top-up on an average Boca home is usually a same-day job. Adding removal of the existing material extends it, because the old insulation has to be vacuumed out and bagged before anything new goes in. Spray foam involves cure time and ventilation of the space afterward. You will get a realistic time estimate in the written scope before you commit to anything, and we do not put a stopwatch promise on a job we have not seen yet.
It will reduce the load your AC has to fight. Whether it fixes the symptom depends on whether insulation was the cause. If your air handler is undersized, your ducts are leaking, or your refrigerant charge is low, insulation will help but it will not solve it. This is exactly why the inspection includes a look at the ductwork. If we think the problem is on the HVAC side, we will say so rather than sell you an attic full of fiberglass that does not fix it.
They handle different mechanisms. R-value slows heat that moves by conduction, through material. A radiant barrier reflects radiant heat, the energy the hot roof deck beams down into your attic. In a climate with our sun exposure, radiant gain is a real share of the problem, which is why a barrier can add meaningful comfort on top of good insulation rather than duplicating it. On an attic that is already well below code on R-value, insulation comes first.
Florida Power & Light runs a Residential Ceiling Insulation Program that pays a flat rebate on qualifying installations. It generally requires an active FPL residential account, whole-house central electric heating and cooling, and an existing verified ceiling R-value below R-8, so it is aimed squarely at homes with very little insulation. FPL also requires the installer to be enrolled in their Participating Independent Contractor program. Ask us and we will give you a straight answer about whether that rebate is on the table for your job. Confirm current terms with FPL directly, since they set them and can change them.
No. The attic inspection and the written scope that comes out of it are free, and there is no obligation attached to either. If the honest answer is that your insulation is fine and your money is better spent elsewhere, that is the answer you will get.
Depth markers get left in the attic and photographed. You will receive photos of the finished work showing the material at the agreed depth, along with the product and its rating. You should not have to take a contractor's word for something buried above your ceiling, and with our jobs you do not have to.
A measured attic inspection, photographs of what we find, and a written scope with the reasoning attached. Free, and no obligation.
