"Upstairs bath water leak with about 400 gallons of water ran into kitchen below. Entire kitchen removed down to studs. They responded within 45 minutes of calling them and had kitchen gutted within 2 hours. Dehumidifiers were placed in all areas affected. Reconstruction went pretty smoothly. We had old Sheetrock with asbestos joint compound that needed removal, hazmat team brought in. New Sheetrock, cabinets, tile and paint. There are always issues with obtaining materials and coordination when you are building. Henry's did a good job of keeping us updated and responding to immediate concerns. Workman were reliable and showed pride in workmanship. We are pleased with the results.

Insulation questions, answered by experts

Installing new insulation in a home is worthwhile if your existing insulation is old and has lost some of its insulative capability or if you don’t have insulation installed already. Installing new insulation will boost your home’s energy efficiency, which can reduce your heating and cooling bills and save money on HVAC repair and maintenance in the long run. New insulation also keeps your living space more comfortable, so you and your family will benefit from the work as well. Finally, installing new insulation boosts your home value, making it especially worthwhile if you plan to sell.

Through R-value assessments based on climate and existing insulation.

You do not always need to remove old insulation before adding new. If the existing insulation is in good condition—not wet, physically damaged, moldy, or infested with pests—you can add new insulation directly on top of it for a compounding effect. You can also mix different types, such as adding blown-in insulation around existing fiberglass batts.

However, removal is recommended if the old insulation is compromised by water damage or pests. You should also remove it if you plan to install a different type of insulation, like switching from roll or batt insulation to spray foam. If the existing insulation is very old or damaged, you will likely get more benefit from removing it and starting fresh.

One of the clearest signs that your insulation isn’t working as well as it should be is a noticeable difference in temperature throughout your home. One room might feel icy while another is hot as Arizona—this indicates that some parts of your home are either retaining or losing heat more than others. Additionally, a sudden increase in your energy bills, evidence of pests or rodents, or evident water damage are other signals that warrant a thorough inspection of your insulation and potential replacement.

Your house may be cold even if the heat is on because of bad insulation, gaps in doors, small holes pulling hot air from the home, or excess humidity. The heater itself might be malfunctioning. For this problem, you’d need to talk to an HVAC pro. If you have a gas heating system (most do) this should be considered an urgent job as natural gas could be leaking in your home.
