Frequently asked questions

ThermaCore Insulation Inc. is a family-owned, licensed and insured insulation contractor based in Stockton, California. The company was founded on 18 March 2026 and works on both residential and commercial properties. Services run from attic and crawl space insulation through to air sealing, removal and duct cleaning.

Yes, all work is carried out as a licensed and insured contractor. That cover applies to residential and commercial projects alike. You are welcome to ask for confirmation before any work is scheduled.

The company was founded in March 2026, so it is genuinely new. What that means in practice is that every project runs to current standards, with licensing, insurance and workmanship warranties in place from the start. Reputation is being built one job at a time rather than inherited.

Coverage includes Stockton, Lodi, Sacramento, Elk Grove, Tracy, Manteca and Modesto. Work also extends to Livermore, Pleasanton and the wider San Francisco Bay Area. If your property sits near one of these areas, it is worth asking whether a visit can be scheduled.

Recommendations are based on what the inspection actually finds, not on what makes the largest job. Estimates are written clearly, so the scope and the cost are visible before anything begins. Properties are protected during the work and cleaned properly before the crew leaves.

You can request an inspection through the contact form on this website at any time. A member of the team will come back to you to agree a suitable visit. Both the inspection and the estimate that follows are free.

Yes, the inspection and the written estimate are provided at no cost. There is no requirement to book work afterwards, and you will not be pressured to decide on the day. Many people use the inspection simply to understand the condition of their property.

Cost depends on the size of the space, the material chosen, the condition of the existing insulation and whether removal is needed. Because those factors vary so much between properties, an accurate figure only comes from an inspection. Your written estimate sets out the full scope and cost before any work is booked.

In most cases the findings are explained during the visit itself. A written estimate follows so you have the scope and the cost in front of you in plain language. If anything in it is unclear, you can ask before making a decision.

Seasonal offers and whole-project discounts are sometimes available, so it is always worth asking. Availability changes, and anything applicable will be reflected in your written estimate. Nothing is added or removed without it being explained to you first.

Common signs include uneven room temperatures, drafts, rising heating and cooling costs, and insulation that looks compressed, damp or disturbed. Older properties built before current California energy standards often carry less insulation than they need. An inspection is the only reliable way to confirm what is actually up there.

Lifespan varies by material and by conditions in the space, and many types can perform for decades when they stay dry and undisturbed. Moisture, rodent activity, compression and roof leaks are the usual reasons insulation fails early. Checking the condition every few years is a sensible habit.

Many homeowners find that improved insulation makes room temperatures feel more even and helps heating and cooling systems work less hard. Results depend on the property, the existing insulation and how well the space is sealed. An inspection will show whether the likely improvement justifies the work at your property.

Not always, as sound existing material can sometimes be topped up rather than replaced. Removal is usually recommended where insulation is wet, compressed, contaminated or affected by rodents. What is right for your property will be explained during the inspection.

Yes, both residential and commercial properties are covered. Commercial work often involves larger spaces, different access arrangements and scheduling around business hours. The sequence stays the same: inspection, honest recommendation, written estimate and professional installation.
