Trusted Home Energy Audit for Santa Monica Homeowners
A home energy audit in Santa Monica typically costs $199-$499 for a full diagnostic including a blower door test and thermal imaging, and most audits take about 2-3 hours from start to finish. That’s the short answer. The longer one involves ocean air, older stucco homes, and attics that leak heat all year round without anyone noticing until the utility bill shows up. Walt’s Insulation has been running energy audits across Santa Monica since 2000, and we’ve probably walked through a house just like yours in Sunset Park, Ocean Park, or north of Montana. Every audit gets the same treatment: a live person answers when you call (424) 396-5828, we show up in uniform, and we tell you exactly what’s costing you money and what isn’t.
What Our Home Energy Audit Service Includes
Blower Door Test
A blower door test measures how much air is leaking through your home’s exterior shell. We mount a calibrated fan in an exterior door frame, depressurize the house, and read how many cubic feet per minute of air are being pulled through gaps, cracks, and penetrations. In Santa Monica, where many homes predate the 1970s and have never been air-sealed, it’s normal for us to find the equivalent of a window left open all year round. The test pinpoints exactly where those leaks are so we can recommend sealing that actually moves the needle, not guesswork.
Thermal Imaging Inspection
Thermal imaging shows us what your walls and ceilings are hiding. We use an infrared camera to scan for hot and cold spots that indicate missing insulation, water intrusion, or gaps around recessed lights and electrical boxes. The marine layer in Santa Monica means moisture gets into wall cavities in ways that Sacramento or Riverside homeowners never deal with, and thermal imaging catches that before it becomes mold or rot. After the scan, we walk you through the images so you can see the problem areas with your own eyes, not just take our word for it.
Insulation Inspection
We physically inspect every accessible area: attic, crawl space, rim joists, and exterior walls. A lot of Santa Monica homes still have original R-11 or even less in the attic, which is nowhere near what today’s building code calls for. We measure exactly what’s there, note any sagging, rodent damage, or moisture-soaked spots, and give you a straight answer on whether adding more insulation is worth the money. When we recommend brands like Owens Corning or Johns Manville, it’s because we’ve installed thousands of pounds of both and know how they hold up in coastal air.
Duct Leakage Test
Most Santa Monica ductwork loses 20-30% of conditioned air before it reaches a single vent. A duct leakage test pressurizes your duct system and measures exactly how much air is escaping into attics, crawl spaces, and wall cavities. That’s air you paid to heat or cool, and it’s doing nothing for you. We find the leaks, show you where they are, and tell you what sealing them will save on your bill. If your ducts are too far gone, we’ll say that too and give you an honest replacement estimate instead of patching junk.

Brands We Service for Home Energy Audit
We work with Owens Corning insulation more than any other brand, and that’s not an accident. Their fiberglass batts and blown-in products hold up well in Santa Monica’s salt air, and we’ve installed enough of it to know exactly how it performs over a decade or two. When an audit turns up attic insulation that’s settled or compressed, Owens Corning is often what we recommend to replace it because the R-value claims actually hold up.
Johns Manville and Rockwool are also in our regular rotation, particularly for homeowners who want sturdier batts or better sound control between rooms. Rockwool’s mineral wool handles moisture better than fiberglass, which matters in a coastal climate where the humidity swings between morning marine layer and afternoon sun. We’ve serviced and installed all three brands for over 25 years, and whether you have Johns Manville, Rockwool, Owens Corning, or something we’ve never heard of, we can run an audit that tells you exactly what condition it’s in and what’s worth replacing.
Signs You Need Home Energy Audit Right Now
- Your utility bill keeps climbing even though your habits haven’t changed. SCE and SoCalGas rates in Santa Monica have gone up repeatedly over the last few years, but if your usage itself is trending upward, that’s air leaking or equipment underperforming. An audit finds the culprit instead of guessing.
- Some rooms are always 5-10 degrees off from the rest of the house. That upstairs bedroom that’s unbearable in August or freezing in January is a red flag. In Santa Monica, it’s almost always a combination of poor attic insulation above the room and duct leaks in the run serving it.
- You feel drafts near windows, doors, or electrical outlets. On a windy day in Ocean Park or the Sunset Park flats, you shouldn’t feel air moving inside a closed house. Drafts mean your envelope is leaking, and every leak is money out the window, literally.
- Your HVAC runs constantly and still doesn’t keep up. A system that never cycles off is either undersized, leaking ducts, or fighting a leaky envelope. The audit separates those three problems so you don’t replace an AC unit when all you needed was air sealing.
- You’ve lived in the home 5+ years and never had an audit done. Most Santa Monica homes change hands without anyone ever checking what’s inside the attic or walls. If you can’t remember the last time someone actually looked at your insulation, that’s long enough.
Our Home Energy Audit Process - Step by Step
- 1
Walk-through and interview. We start by asking about the rooms that bother you, the bills that feel too high, and any history you know about the house. Ten minutes of conversation tells us more than any checklist. Walt Brenner started this company in 2000 because he got tired of techs who never listened, and that habit stuck.
- 2
Blower door and pressure testing. We set up the calibrated fan in an exterior door and depressurize the house to a standard 50 pascals. While the house is depressurized, we walk every room with a smoke pencil and thermal camera, marking every leak we find on a floor plan. You’re welcome to follow along and see the leaks yourself.
- 3
Thermal imaging sweep. With the house still depressurized, the infrared camera shows us where air is entering and where insulation is missing or wet. Walls, ceilings, floors, around can lights, behind outlet covers: all of it gets scanned. We save the images and show them to you before we leave.
- 4
Duct and combustion safety checks. We test duct leakage and verify that any gas appliances are venting properly. A tight house is great, but not if it backdrafts a water heater into your living room. That’s a step a lot of auditors skip, and it’s one we never will.
- 5
Report and recommendations. Before we leave, you get a plain-English summary of what we found, what it’s costing you, and what we’d fix first if it were our house. No 40-page binder, no upsell pressure. Just a list, in order of payback, with prices. If you want a second opinion on anything, that’s free too.
How Much Does Home Energy Audit Cost in Santa Monica?
Here’s the honest part: an audit that costs $399 but finds $1,200 a year in air leaks is not an expense, it’s an investment with a three-month payback. We don’t charge a trip fee inside our service county, and if you’ve got a written estimate from anyone else, we’ll give you a free second opinion on it. Call (424) 396-5828 and ask for a straight number before we book anything. We’ll tell you what it’ll cost and what you get, and then you decide.

Frequently Asked Questions - Home Energy Audit in Santa Monica
What is a home energy audit?
A home energy audit is a diagnostic evaluation that measures exactly where a house is losing energy and shows you which fixes will actually save money. It combines a blower door test, thermal imaging, an insulation inspection, and duct testing to find leaks and gaps that you can’t see from the outside. In Santa Monica, where most housing stock is 40-70 years old, an audit almost always uncovers problems that a visual inspection misses. Walt’s Insulation has been running these audits since 2000, and our reports tell you what to fix first, what to skip, and what to expect in savings.
How long does a home energy audit take?
Plan on two to three hours for a full audit of a typical Santa Monica single-family home. Smaller condos or apartments take less time, usually 90 minutes to two hours, while larger homes or ones with difficult crawl space access can run three to four hours. We set up the blower door, run the thermal scan, check every accessible cavity, and walk you through the findings before we leave. You’ll have results in hand the same day, not three weeks later in the mail.
How much does a home energy audit cost in Santa Monica?
Most audits in Santa Monica run between $199 and $499, depending on home size, access, and whether you want the full suite of tests or just a blower door and visual check. We don’t charge a trip fee inside our service county, and seniors and veterans always get 10% off. Call (424) 396-5828 for an exact quote before we book anything, and remember you’ll get a free second opinion on any written estimate you already have.
Do you service homes with Owens Corning or Rockwool insulation?
Yes. We’ve installed and inspected thousands of Owens Corning and Rockwool jobs over the last 25-plus years, and we know exactly how both perform in Santa Monica’s coastal climate. Whether you have blown-in fiberglass, mineral wool batts, or a mix from a previous owner, we can evaluate its condition, depth, and R-value during your audit. If it’s failing, we’ll tell you what to replace it with and why brand matters less than installation quality.
Can you come today for an emergency energy audit?
If you’ve got a serious problem like water intrusion, a major air leak, or a system that’s failing during a heat wave, call (424) 396-5828 and a live person will answer, any hour of any day. We’ll tell you honestly whether it’s a true emergency or something that can wait a day or two. For most audits in Santa Monica, we’re inside your home within 24 to 48 hours, and we don’t make you leave a voicemail to schedule.
Is your home energy audit work guaranteed?
Every audit we perform is backed by the Done Right Promise: if it’s not done right, we make it right, no runaround and no fine print. That’s a lifetime workmanship guarantee from a company that’s been locally owned and operated in this community since 2000. Walt Brenner puts his name on this business, and he doesn’t hide behind an 800 number or a franchise manual.
How should I prepare for a home energy audit in Santa Monica?
Not much prep is needed. Close all windows and exterior doors an hour before we arrive, make sure any pets are in a safe spot since we’ll be opening the front door repeatedly, and gather a few recent utility bills if you have them. It also helps to think about which rooms feel uncomfortable and when, so we can target those areas specifically. We’ll handle the rest, and we’ll explain everything as we go.
