"I would highly recommend John P. Insulation. I got three quotes for my insulation job and they were the most professional during the estimate. They provided pictures of what they were going to do. They fully explained the job and what I should expect. The quote was fast and equal or lass than the others. On the installation day, they arrived when they said they would, covered my floors and completed the work exactly as they said they would. I had them foam seal, blow in insulation, install soffit vents and vent a bathroom fan. You will not be disappointed in the quality."

Insulation questions, answered by experts

Plaster itself has a higher R-value than drywall. However, there are other considerations surrounding plaster and insulation. As a general rule, it's easier to obtain consistency in insulating value and quality when working with drywall rather than plaster. Plaster walls often don't contain any insulation behind the wall covering by design, and careful evaluation is necessary when choosing to add it.

While carpet over carpet may provide some additional insulation and soundproofing benefits, it's not as effective as other methods. Layering carpets can add a modest buffer against noise and temperature fluctuations, but it's limited compared to installing thicker carpet padding or using specialized soundproofing materials. For optimal floor insulation and soundproofing, consider alternative solutions tailored to your specific needs and budget, such as adding additional padding or soundproofing underlayments beneath the carpet.

Water heater blanket prices range from $20 to $40 on average, though you typically won’t need to spend more than $30 for all the tools and materials required for installation—which include the blanket itself, heavy-duty scissors, and electrical tape. Blankets with higher R-values will also be slightly higher in price.

Yes, it is possible to have too much insulation, which can have detrimental effects. While more insulation might seem better for energy efficiency, a home needs to "breathe" or ventilate to release moisture that accumulates inside. Over-insulating can seal a house too tightly, trapping water vapor and leading to several problems, including mold, mildew, and condensation. Homes in warm, humid climates are particularly susceptible to mold, while those in colder climates can experience condensation from temperature fluctuations. Additionally, adding more insulation than the recommended amount for your climate may not provide recoverable energy savings. To avoid these issues, consult a professional insulation contractor who can determine the optimal amount of insulation for your home.

Expect your home insulation project to take between five and 12 hours to complete on average for batts or boards and two to five hours for spray foam or blown-in insulation. It might take longer if you need to remove your home’s existing insulation, you have a higher-than-average square footage, or accessibility is limited.
