Insulation Contractor in National City, CA

What insulation does for your home

Insulation keeps the heat out in summer and in during winter, so your AC and heater work less. You feel it as a more even temperature from room to room, a quieter house, and lower bills.

It also matters before the walls close. Once the drywall is up, fixing a gap means cutting the wall open, so we do it right the first time.

New homes, remodels and commercial work

Most of our insulation goes into new homes, room additions and remodels, after the framing and before the drywall. We also take commercial jobs, small commercial spaces, multi-unit buildings, steel buildings and roll-up doors, and we install closed-cell spray foam where it fits. On a new build we can run insulation, drywall, texture and paint as one crew, so the next trade never waits on us.

What goes where: real numbers from our jobs

On a recent full house we put R-30 in the roof, R-21 in the exterior walls, R-13 in the interior walls and R-19 under the subfloor. On another, R-38 in the ceiling and R-15 in the exterior walls. In attics we usually blow in R-38. The plans and the space decide the numbers; we follow them.

Quieter rooms and fire walls

Insulation is also for sound. On one job we took the ceiling down, installed mineral wool and RC channels to cut the noise from the second floor, and closed it with 5/8-inch drywall. Between units, a demising wall gets rockwool for fire and sound.

Vaulted ceilings need a different plan

Every project is different. In a vaulted ceiling there is no attic above to breathe, so we install rigid board first to help keep moisture out, then fiberglass rated for the space, for example R-30. A flat ceiling under an attic is a simpler job.

Old insulation, rodents and crawl spaces

If the old attic insulation is flat, dirty or full of droppings, new insulation on top of it is money wasted. See attic clean-up. Under a raised floor, a damp crawl space is a separate job: see crawl space encapsulation.

Also part of our insulation work

Attic Clean-Up and Insulation Removal: We take it out, clean the attic and put new insulation in.
Crawl Space Encapsulation: We seal it against the ground moisture.

Where we do this work

Inland homes in places like Escondido fight summer heat, while homes near the coast deal more with moisture, so the plan changes with the address. We work from National City and take insulation jobs across San Diego County, including Bonita, Rancho Santa Fe, Julian and San Marcos. See all the areas we serve.
