What we install

Six Attic insulation services in Fontana. One crew.

Every job starts with an attic inspection and a fixed bid. We measure your current R-value before quoting.

Blown-In Insulation

Loose-fill fiberglass or cellulose blown to an even R-38 or higher, filling the gaps batts leave behind.

Batt Insulation

Fiberglass batts for walls, garages and accessible attic sections that need a clean, dense fit.

Radiant Barrier

Reflective barrier stapled to the rafters that reflects radiant roof heat before it loads the attic. Big win in IE sun.

Air Sealing

Sealing top plates, can lights and penetrations so conditioned air stops leaking into the attic.

Attic Ventilation

Intake and exhaust venting, plus solar attic fans, to move trapped heat out instead of down.

Old Insulation Removal

Safe removal of compressed, rodent-damaged or contaminated insulation before the new install.

How it works

Frequently asked

Attic Insulation FAQ - Fontana & Inland Empire.

How much does attic insulation cost in Fontana?

Most attics run $1.50-$3.50 per square foot, so a typical home lands around $1,800-$4,500 depending on size, target R-value and whether old insulation is removed. Radiant barrier adds a bit.
We give a fixed bid after inspecting.

What R-value do I need in the Inland Empire?

California Title 24 calls for about R-38 in attics for our zone. Many older Fontana homes measure R-13 or less, so the upgrade makes a noticeable diﬀerence.

Is radiant barrier worth it here?

In IE sun, yes. Radiant barrier reflects the roof’s radiant heat before it hits your insulation,and pairs well with blown-in to keep attic temps and AC runtime down.

How long does it take?

Most homes are done in one day. Removing old insulation or adding a full radiant barrier can push it to two.

Do you offer financing?

Yes. Through HFS Financial and HERO/PACE, from $89/mo, 0% APR for 18 months, $0 down for qualified homeowners. Pre-qualify in 60 seconds without aﬀecting your credit.
