Rockwool Home Energy Audit in Santa Monica: What to Know First

An independent Rockwool home energy audit in Santa Monica typically runs $195 to $450 depending on home size and how many tests you want done. We perform blower door tests, thermal imaging, and insulation inspections specifically tailored to Rockwool installations, with most audits completed the same week you call. If your Rockwool batts or boards were installed years ago in an older Santa Monica home, the audit almost always finds gaps you didn’t know existed. Call (424) 396-5828 and a live person answers, day or night.

This page is for homeowners who already have Rockwool insulation and want to know if it’s actually doing its job. If you’re wondering whether the marine air off the Pacific is undermining your insulation, or why your upstairs feels like a sauna in August, this is the right place to start.

How Rockwool Products Fail - and How We Fix Them

Rockwool makes good insulation. We install it. But even good products fail when they’re installed wrong or when Santa Monica’s coastal humidity gets to work on them. Here’s what we find during home energy audits in Santa Monica homes, and what we do about it.

• ComfortBatt compression in 2×4 walls. Rockwool ComfortBatt R-15 is designed for 2×4 wall cavities, but when someone stuffs R-23 batts meant for 2×6 framing into a 2×4 wall, the insulation compresses and loses R-value fast. We see this a lot in older bungalows near Montana Avenue where well-meaning contractors “upgraded” the walls without checking the cavity depth. The fix is a careful removal and replacement with the correct batt, which we verify with thermal imaging right after install.
• Safe’n’Sound used as thermal insulation. Rockwool Safe’n’Sound is superb for interior soundproofing but it’s not designed as a primary thermal barrier. In Santa Monica, we occasionally find attics where someone used Safe’n’Sound batts because that’s what they had left over from a remodel. It won’t keep heat out the way ComfortBatt or ThermaBatt does. Our audit identifies this misapplication, and our fix is straightforward: the right Rockwool product in the right place.
• ComfortBoard gaps at exterior transitions. Rockwool ComfortBoard is rigid and excellent for continuous exterior insulation, but it has one common failure point in coastal climates: the seams between boards. If those seams aren’t properly staggered and sealed, moist ocean air gets behind the board and condenses against the sheathing. During a blower door test combined with thermal imaging, we can pinpoint exactly where air is moving behind those seams. The fix usually isn’t a full redo; it’s targeted sealing and, when needed, replacing of sections where the board has absorbed moisture.
• Attic batts displaced by pest activity. Rockwool is pest-resistant, but it’s not pest-proof. Rats and squirrels in Santa Monica attics will still tunnel through batts to create nesting areas, and that tunneling destroys the insulation’s continuity. We regularly pull back Rockwool batts in older homes near Lincoln Boulevard and find tunnels running right through the middle. The audit catches this with thermal imaging; the fix is removal, rodent proofing, and fresh insulation.
• Settling and sagging in cathedral ceilings. Rockwool batts in sloped cathedral ceilings tend to sag over time, particularly in homes within a few blocks of the beach where humidity cycles are more extreme. Gravity plus moisture equals sagging, and once a batt sags, it creates an air channel along the roofline. Our home energy audit in Santa Monica includes checking these ceiling cavities with thermal imaging, and our repair method depends on how far the sag has progressed – sometimes it’s as simple as re-securing the batts, sometimes it’s replacement.

Our Rockwool Home Energy Audit Process

When you call us, here’s how a Rockwool home energy audit in Santa Monica goes, step by step. It’s the same process Walt’s crew has refined since the early 2000s, and we don’t skip any part of it.

1. 1
   Call and schedule. You call (424) 396-5828. A live person answers – not a voicemail, not an answering service. We’ll ask about your home’s age, square footage, and what specifically is bothering you: hot upstairs, cold floors, weird drafts, high energy bills. Then we schedule a time that works for you, and there’s no trip charge if you’re in our service county.
2. 2
   Walkthrough and visual inspection. Our background-checked, uniformed technician arrives and does a full walkthrough, inside and out. We check insulation levels in the attic, look at wall cavities where accessible, and inspect every gap around windows, doors, outlets, and plumbing penetrations. We’re looking specifically at how your Rockwool is installed and whether it matches what the manufacturer specifies for that cavity depth.
3. 3
   Blower door test. We set up a calibrated blower door fan in an exterior door frame and depressurize your house. This tells us exactly how leaky your envelope is, measured in CFM50. For Santa Monica homes within a few blocks of the ocean, we often see higher numbers because marine air movement through the envelope is constant. The blower door test confirms where the leaks are and how big they are.
4. 4
   Thermal imaging inspection. With the blower door still running, we scan every wall, ceiling, and floor with an infrared camera. This catches missing insulation, compressed batts, moisture behind ComfortBoard, and pest tunnels that a visual inspection would never reveal. You’ll see the images yourself, so there’s no guesswork and no vague “trust us” explanations.
5. 5
   Duct leakage and insulation review. About 20 to 30 percent of conditioned air escapes through duct leakage in the typical older Santa Monica home. We test your duct system for leakage and inspect every accessible duct joint. If we find problems, we’ll show you exactly where they are before we touch anything.
6. 6
   Report and recommendation. Before we leave, we sit down with you and go over everything we found. You get a clear, written summary with photos, and we’ll tell you honestly what needs fixing and what can wait. If you already have an estimate from someone else, bring it – we’ll give you a free second opinion on it. And there’s never pressure to sign anything on the spot; a forced decision is a bad decision in home energy work.

What Rockwool Home Energy Audit Costs in Santa Monica

A Rockwool home energy audit in Santa Monica costs between $195 and $450 for most homes. Here’s what moves the price:

The size of your home, the age of the construction, and how much testing you want all factor in. Older bungalows near Montana Avenue tend to need more time because there are more cavities to check and more surprises behind the walls. Newer builds closer to the water are usually faster but often reveal poorly sealed envelope details that the original builder skipped. Every audit comes with upfront pricing, so you’ll know the cost before we start. And if you’re a senior or a veteran, take 10 percent off the top – that’s permanent, not a special.

Our technicians know Rockwool because they install it, inspect it, and repair it every week. They also work with Owens Corning, Johns Manville, Knauf, CertainTeed, Icynene, Demilec, GreenFiber, and Reflectix, so when we tell you your Rockwool is failing, we can tell you exactly what we’d replace it with and why. And every job is covered by the Done Right Promise: if it’s not done right, we make it right. No runaround, no fine print. Lifetime workmanship.
