Energy efficient homes

Insulation slows heat. Air sealing stops it.

Most homes are not under-insulated so much as they are leaky. Batts sit in a cavity while air moves freely around them — through the top plates, the can lights, the rim joist and every gap the framing left behind. Spray foam is different because it does both jobs at once: it fills the cavity and bonds to every surface it touches, so the air stops moving.

San Diego Spray Foam was founded in 2022 by Vlad Gordievsky, an MIT-educated mechanical engineer who got into this trade the hard way — by insulating his own house and then watching a previous employer overcharge for the same work. We are genuinely interested in building science, and it shows up in the quote you get.

Our services

Three places foam earns its keep

Every project starts with a walkthrough. We assess the assembly you actually have and recommend the material that suits it — open-cell, closed-cell, or something else entirely if foam is not the right answer.

Most requested Attic roof deck and gable ends fully covered in spray foam insulation.

Attics & basements

Start at the top. Sealing the roof deck or ceiling plane cuts the stack effect that pulls conditioned air out of the house, then rim joists close the biggest remaining leaks below.

Metal garages & buildings

Closed-cell foam sprayed straight to the panel kills condensation, seals every rib and seam, and turns a steel shell into a shop you can actually work in year round.

Metal buildings

Remodels & new builds

The cheapest time to get the envelope right is while the studs are open. We work to the builder’s schedule, trim flush for drywall and leave the site clean.

Common questions

Straight answers before you call

What is the difference between open-cell and closed-cell foam?

Open-cell foam is lighter and more flexible, yields more coverage per set, and works as a strong air barrier and sound dampener. Closed-cell is denser, gives a higher R-value per inch, adds rigidity to the structure and acts as its own moisture barrier.

Closed-cell is the usual pick for metal buildings, rim joists and foundation walls. Open-cell often makes more sense on interior walls and vaulted ceilings. We recommend the material that suits the assembly, not the one that is easiest to sell.

Do you offer free estimates?

Yes. Every project starts with a free at-home insulation quote on site. We walk the space with you, discuss the options and give you an honest quote with no hidden costs.

Where should I start if my house is uncomfortable?

Almost always the attic or ceiling. Picture the house as a cylinder with warm air escaping out of the top — capping the top first cuts the biggest driver of air movement through the building.

After the attic, the next best move is usually the rim joists around the perimeter of a basement or crawlspace, where the largest remaining leaks tend to hide.

How long does a spray foam job take?

Most residential projects can be quoted and completed within a month, often sooner. The spray itself is typically one to two days on site depending on square footage and how much prep the space needs.

Do I need to leave the house while foam is installed?

For occupied homes we mask and ventilate the work area, and you should plan to stay out of the sprayed space while we work and through the re-occupancy window afterwards. That window is set by the specific product we use, so we give you the exact time frame before we start rather than a guess.

Can you insulate a metal garage or steel building?

Yes — metal buildings are one of our specialties. Closed-cell foam sprayed straight to the panel stops condensation, seals every rib and seam and makes the space conditionable. We mask lifts, doors, vehicles and equipment before anything gets sprayed.

Are you licensed and insured?

Yes. We are licensed and insured, and happy to provide documentation before work begins.
