Drafty rooms and high PG&E bills often trace back to walls with little or no insulation. We fix that - without tearing out your drywall.
Wall insulation in Rohnert Park slows the transfer of heat through your exterior walls, keeps rooms comfortable year-round, and most residential jobs wrap up in one day.
Most homes in Rohnert Park were built between the 1960s and 1980s, well before California required meaningful wall insulation. If you feel a temperature difference between rooms, notice your heating and cooling running constantly, or watch your PG&E bill climb every summer, under-insulated walls are a likely cause. The good news is that finished walls can be insulated without tearing out your drywall - a process that pairs naturally with air sealing services for the best comfort results.
Wall insulation also reduces how much outdoor air - including wildfire smoke during Sonoma County fire seasons - can infiltrate your living space. That makes it a health and comfort investment, not just an energy bill fix.
Rohnert Park's older neighborhoods were largely built before California required meaningful wall insulation. If your home is from that era and no one has ever upgraded the insulation, there is a good chance your walls are empty or filled with material that has broken down over decades. You do not need to open a wall to find out - a contractor can assess this during a free estimate visit.
If one bedroom is always stuffy in summer or a corner of your living room feels drafty in January, that is a classic sign of missing or inadequate wall insulation. Heat moves toward cold, and without insulation to slow it down, exterior walls become the path of least resistance. This is especially common in Rohnert Park homes where afternoon sun hits west-facing exterior walls hard.
When your heating or cooling runs longer than it should to maintain a comfortable temperature, it is often fighting heat loss through uninsulated walls. You might notice unusually high PG&E bills during summer or winter, or a system that seems to run almost continuously. Insulating the walls is often the most effective fix for this problem in older homes.
On a cold morning, press your hand flat against an interior wall surface that backs up to the outside. If it feels noticeably cold compared to interior walls, heat is escaping through the wall cavity. In a well-insulated home, exterior walls feel close to room temperature on the inside - not cold to the touch.
For finished walls - the most common situation in Rohnert Park homes - we use blown-in dense-pack insulation. We drill small access holes, fill each wall cavity completely, then patch and paint the holes so the work is nearly invisible when done. This approach works with your existing drywall and requires no demolition. It pairs well with blown-in insulation upgrades elsewhere in your home.
For homes undergoing a renovation where walls are already open, we install batt insulation between studs before drywall goes up. We also perform thorough air sealing at the same time, since insulation alone leaves gaps that air can still move through. If you want the full picture on sealing your home, our air sealing services page covers that process in detail.
Best for finished homes where walls are closed - no drywall removal needed.
Ideal for open walls during a remodel or new construction project.
Suited for older homes where wall cavities may have settled material that needs to be fully displaced and replaced.
Recommended alongside any wall insulation job to close gaps that insulation alone cannot address.
Rohnert Park sits in Sonoma County's inland corridor, where summer afternoons can push into the 90s and winter nights regularly drop into the 30s. That wide swing means under-insulated walls cause real discomfort in both directions - rooms that bake in July and feel drafty in January. Unlike coastal cities with more moderate temperatures, Rohnert Park homeowners feel the impact across all four seasons. The city was also developed rapidly as a planned community starting in the late 1950s, and a large share of single-family homes predate California's energy codes. If you live in one of those older neighborhoods, your walls may be empty or filled with degraded material.
