Houston sits in the Mat-Su Valley and has a true cold-climate winter. In a typical January, daytime highs average about 19°F and overnight lows drop to around 3°F. Snow is usually measurable from October into April, and a typical year brings roughly 64 inches of it. According to the U.S. Department of Energy, air sealing and proper insulation can significantly cut heating and cooling costs in homes, shops, and outbuildings running heating equipment for much of the year.
That long heating season puts pressure on any gap in the building envelope. Warm indoor air escapes through rim joists and wall cavities, while cold air leaks in. Crawl spaces and floors over unheated areas can stay cold and damp. Spray foam helps because it insulates and air seals in the same step, so open-cell and closed-cell options are worth comparing before winter returns.

Closed-cell gives more R-value per inch and resists moisture, so it is often used in crawl spaces, rim joists, and barns. Open-cell suits interior walls where there is room for more depth.
Often yes, in crawl spaces, rim joists, and exposed framing. Walls closed in by drywall usually need to be opened first.
Manufacturers set minimum air and surface temperatures for the foam, so cold-season jobs may need a heated space. The team will tell you what applies to your schedule.
It can reduce it, because foam applied directly to the metal keeps warm, moist air from reaching a cold surface. Proper thickness and full coverage still matter.
Codes set by organizations like the International Code Council often require a thermal or ignition barrier over exposed foam, depending on where it is installed and how the space is used. Polyseal can confirm what applies to your building.
Re-entry time depends on the foam product and ventilation. Ask for the specific time before work starts and keep children and pets out until then.
Ask about foam type, thickness and R-value, the area covered, the thermal barrier plan, and re-entry time.
Foam type, thickness, square footage, access, and prep work all change the price, so compare quotes like for like.
