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

Four steps. One day. Done right.

Most Fontana attics finish in a single working day. Removal and full radiant-barrier jobs can run two.

Attic Inspection

Free visit to measure current R-value, check ventilation and air leaks, with a fixed bid in 48 hours.

Plan & Prep

We confirm the target R-value and rebate eligibility, then mask and protect your living space.

Remove & Seal

Remove old insulation if needed, air-seal penetrations, and set up clean ventilation.

Install & Clean

Install radiant barrier and blow in new insulation to depth, then vacuum and haul debris away.

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.

 Trustindex verifies that the original source of the review is Google. Moses team helped us converting our backyard to a beautiful sitting area. Moses helped a lot with arranging everything and consultation. They finished the job in just a few days without cutting corners and exactly as we asked them to do. Although they were not cheap, but I think their quality of work was worth the money.

 Trustindex verifies that the original source of the review is Google. We had a wonderful experience working with Manny on our landscaping project.
The quality of their work was outstanding.
Everything was completed to a high standard, and the attention to detail really showed in the final result.
Perhaps most importantly, they finished the project a few days ahead of schedule, which exceeded our expectations.
Overall, a very professional and reliable team, we would definitely work with them again!!

 Trustindex verifies that the original source of the review is Google. Our landscaping project was just finished by West Coast Home Remodeling. After a lot of confusion on our end, we are very happy with the final design and the way it came out.
Zack really helped us understand what will work for our vision, needs and budget.
The whole yard feels like a proper hangout spot instead of unused space and that’s exactly what we were aiming for!

 Trustindex verifies that the original source of the review is Google. Shawn and the team worked very quickly and professionally to transform our entire backyard into a kid friendly paradise (removed an old patio and dead grass and installed patio pavers, turf, DG, hedges). There were a few instances where things weren’t exactly as we wanted them, and Shawn was quick to address to our satisfaction. I’ve already recommended the team to others who are looking to do yard transformations.
