Your AC should not have to fight your own attic all summer. We spray foam that seals and insulates at the same time, so your home actually holds the temperature you set.
Spray foam insulation in Downey, CA expands on contact to seal gaps and insulate in a single step, most jobs take one to two days for a standard home.
If your home was built before 1980 - which covers a large share of Downey neighborhoods - your attic and walls are probably under-insulated by today's standards. Heat pours in through the ceiling all summer, and your air conditioner runs harder and longer than it should. Spray foam stops that at the source.
Many homeowners in Downey pair spray foam with attic insulation work to get the full benefit - sealing air leaks and then adding thermal mass to slow heat transfer. Together, the two approaches address the biggest reason older homes stay hot even with the AC on.
If your air conditioner runs constantly during a Downey summer but certain rooms still feel stuffy or hot, heat is likely pouring in through a poorly insulated attic. Go into your attic on a warm afternoon - if it feels dramatically hotter than the rest of the house, that heat is moving through your ceiling into your living space. Spray foam in the attic can stop that heat transfer at the source.
If your electricity bills keep rising even though your habits have not changed, your home's insulation may be failing. Older Downey homes built in the mid-20th century often have insulation that has thinned, settled, or degraded over decades. When insulation loses its effectiveness, your HVAC system works harder and you pay for it every month.
Hold your hand near an electrical outlet on an exterior wall on a warm day. If you feel warm air seeping in, your walls have air gaps that insulation has not sealed. Spray foam is one of the few insulation types that seals those gaps at the same time it insulates, making it the right fix for older homes with drafty walls.
Homes built before modern energy codes were often insulated minimally or not at all in certain areas. If your Downey home was built in the 1950s, 60s, or 70s - which describes a large portion of the city's housing stock - there is a good chance the attic and walls are significantly under-insulated. A quick inspection confirms whether you are losing energy you are paying for.
We install both open-cell and closed-cell spray foam depending on where you need it and what your home requires. For attics and exterior-facing spaces in Downey's hot climate, closed-cell foam insulation is usually the right call - it delivers a higher R-value per inch and also acts as a moisture barrier. For interior walls, open-cell foam is softer, more cost-effective, and adds a layer of sound dampening on top of the thermal benefit.
Both types create an air seal as part of the installation, which is something fiberglass batts and blown-in materials cannot do on their own. That air sealing is often where the biggest energy savings come from - stopping conditioned air from escaping and hot outside air from getting in through every small crack and gap in your home's envelope.
Best for attics, crawl spaces, and any area exposed to heat or moisture. Highest R-value per inch and doubles as a vapor barrier.
Well suited to interior walls and indoor spaces where you want insulation and sound dampening at a lower cost per square foot.
Downey sits in the Los Angeles Basin, where summer temperatures regularly climb into the 90s and air conditioning runs for months at a stretch. Most of the city's housing stock was built between the 1940s and 1970s - a period when insulation was minimal by today's standards. Many of these homes have little to no insulation in the walls and only a thin layer in the attic, if any. That means there is often a real opportunity for spray foam to make a dramatic improvement.
California also has strict air quality rules about the products used in spray foam, so hiring a contractor who knows state requirements matters here - not just national ones. We serve homeowners throughout Downey and neighboring cities including South Gate and Norwalk, so we know the housing stock and local permit requirements across the area.
We will ask a few basic questions about your home - its age, where you want insulation, and what problems you have noticed. We reply within 1 business day and come to you prepared.
A contractor visits your attic, walls, or crawl space to check existing conditions, look for moisture or damage, and measure the area. This visit is free and takes about an hour.
You receive a written quote breaking down the work, foam type, and total cost. We tell you upfront whether a permit is needed and handle pulling it for you - no surprises.
The crew arrives, masks off the area, and applies the foam - it expands and hardens in seconds. Most jobs finish in one day. We walk you through the finished work before we leave and confirm your re-entry time.
Free estimate, no pressure, no obligation. We will tell you exactly what your home needs.
A large share of Downey homes were built in the 1950s and 60s with minimal insulation and irregular cavities. We have worked on these homes extensively and know what to expect before we ever open the attic hatch.
We use foam formulations that meet California air quality standards. We give you a clear re-entry timeline before work begins and make sure the home is properly ventilated before your family returns.
Unpermitted work can cause serious problems when you sell your home. We handle the permit process with the City of Downey Building and Safety Division so your job is documented, inspected, and fully above board.
The Spray Polyurethane Foam Alliance sets best practices for installation and safety. Working with contractors who follow these standards means you get a job done to a documented quality level, not just whatever the crew decides on the day.
Every one of these details connects to a simpler promise: when we finish a job at your Downey home, you will know what was done, why it was done, and that it was done correctly.
Add thermal mass to your attic alongside air sealing for a complete approach to cooling your Downey home.
