Start from what you have noticed

People know what they have noticed rather than what it is called. Each of these points at a different job — and a different level of urgency.

Upstairs runs hot however long the AC is on Usually thin attic insulation, and often a radiant gain problem too. You can see the tops of the joists in the attic There is very little up there. This is the cheapest big gain. Rodents have been in the attic Remove and replace, and seal the way in — in that order. Drafts near ceiling lights and the attic hatch Air sealing. Insulation slows heat; it does nothing about moving air. Floors cold underfoot over part of the house Crawlspace. Deal with the ground moisture before any insulation. Several quotes and no way to compare them Get an audit. It is the cheapest thing here and it settles the argument.

What we can help with

Can wait Attic Insulation The cheapest large gain in most California houses. A lot of older stock here has R-11 or bare joists — the current standard is several times that, and the attic is the easiest place to fix it. What to look for → This week Insulation Removal For insulation that has been soiled by rodents, wet from a leak, or smoke-damaged. Covering contaminated material with new insulation seals the problem in rather than fixing it. What to look for → Can wait Air Sealing Insulation slows heat; air sealing stops air. Most disappointing insulation jobs are disappointing because only the first half was done — and in California it is also what keeps wildfire smoke out. What to look for → Can wait Wall Insulation For finished walls with empty or settled cavities — dense-packed through small access holes. A large share of pre-1980 California walls have nothing in them at all. What to look for → Can wait Crawlspace Insulation Common through the Bay Area and northern California. Deal with the ground moisture first — batts installed over a damp crawlspace fall down within a couple of years. What to look for → Can wait Spray Foam Insulation Genuinely the right answer for rim joists, cathedral ceilings and unvented assemblies. For an open attic deck, batts or blown-in do the same job for a fraction of the cost. What to look for → Can wait Blown-In Insulation The default for an open attic floor, and usually the right one — it flows around joists, wiring and penetrations that batts leave gaps at. Judge it on measured depth, not bag count. What to look for → Can wait Radiant Barrier Genuinely useful in hot, sunny inland California, where it cuts radiant gain into the attic. Not a substitute for insulation, and close to pointless on a coastal fog-belt house. What to look for → This week Rodent Damage and Insulation A large share of California attic work starts here rather than as an energy upgrade. Remove, clean, then seal the way in — replacing insulation without exclusion buys about a year. What to look for → Can wait Home Energy Audit The cheapest thing on this list and the one that stops you buying the wrong work. Blower door, thermal imaging, duct leakage — a measured list of what your house actually needs. What to look for →

Where insulation money gets wasted

Sequence, first. Insulation slows heat moving through a surface; it does nothing about air moving through a gap. Blowing insulation over unsealed top plates, can lights and plumbing penetrations buries the problem under the solution, and it is invisible the moment it is covered. Air sealing comes first, and it should be itemized separately so you can see you paid for it.

Spray foam, second. Foam is genuinely the right answer in a rim joist, a cathedral ceiling or an unvented roof assembly. On an open, accessible attic floor it does the same job as blown-in for several times the price. If a quote proposes foam across an open attic, get a second one.

Third, verification. Loose-fill is billed by the bag and delivered by depth, and the two only match if somebody checks. Depth markers left in place and a photograph of the finished depth cost nothing and are the only way to know what you got.

And in California there is a fourth: a great deal of attic work starts as rodent damage rather than as an energy upgrade. Replacing soiled insulation without closing the entry point buys about a year.

California specifically

Wildfire smoke is the single biggest thing that makes Californians think about what their ducts are carrying. Fine particulate gets pulled into a return during a smoke event and keeps circulating long after the air outside has cleared.

California is also the one state where duct leakage is routinely tested: Title 24 requires a HERS-verified duct test on most furnace or air-conditioner changeouts, so a duct problem here often surfaces as a failed test rather than as a complaint.

How it works

Three steps, and you decide at the end of them.

  1. 1

    You call and describe the problem

    Tell us what you have noticed and where — the room, the smell, the noise, how long it has been going on. Give us your ZIP code and we will match you to a licensed company covering your area. There is no form to fill in.

  2. 2

    A local company takes it from there

    They discuss the problem with you directly, arrange a time to inspect, and agree the work and the price with you before anything starts. That conversation is between you and them.

  3. 3

    You decide whether to go ahead

    You are under no obligation. If the quote or the approach is not what you wanted, you are free to say no and call someone else.

Common questions

Which areas of California do you cover?

All of it. The quickest way to find out about your own town is to call and give us your ZIP code — if the nearest company is an hour out we will say so rather than waste your afternoon.

How soon can someone come out?

Often within a couple of days. Most of this work is scheduled rather than emergency — the exception is a restricted dryer vent, which is a fire risk and should not wait.

Are the companies licensed and insured?

Yes. We only pass calls to licensed, insured operators working in California, and you are welcome to ask to see a license number on arrival.

What does it cost?

Nothing. We are a referral service: the installers pay us for the introduction, you do not, and you are under no obligation to go ahead with whatever they quote. We are not the company that attends, so the price, the schedule and the guarantee are agreed between you and them.
