"The fellows did a great job with this house.  The work is really quite excellent, and they kept us informed with how long it would take, how it was going, and could speak in understandable sentences.  They were polite and they worked very quickly.  
We were amazed and how quickly they did this job, as it was perfect and not at all sloppy, which you easily see in others who are quick and sloppy.  They were anything but.   They cut around several outlets and exterior items on the house and that was done well.  I would definitely recommend to anyone.  We also cannot believe how much WARMER THE BACK OF THE HOUSE is now - especially as it faces NORTH and was quite cold for the last 15 years.  We hope to be able to have them do the rest of the house as we like the insulation put in and the type and quality of siding that was used.  We would recommend most definitely."

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

"I recently had the pleasure of working with Middle Water LLC for spray foam insulation on a client's home and was thoroughly impressed by their professionalism and quality of work. The team consistently showed up on time and adhered strictly to the bid they provided, showcasing their commitment to reliability and integrity. Their dedication and work ethic, particularly the impressive contributions from the hardworking Amish labor, were remarkable. Based on this experience, I have confidently referred Middle Water LLC to another client, who is now planning to use their services as well. The excellent job they did, combined with their punctuality and adherence to the bid, make them a standout choice for insulation services. I am so satisfied with their work that I intend to use them for my own home, which I plan to build in the near future. Middle Water LLC has earned my highest recommendation for anyone seeking top-notch spray foam insulation for their home or business."

Insulation questions, answered by experts

Air duct insulation typically lasts for 10 to 15 years or even longer, depending on the material and maintenance. It's important to conduct periodic inspections to check for signs of deterioration, such as water damage, tears, or general wear. If you find any of these issues, it may be time for repairs or a full replacement. You might also consider upgrading your insulation even if it's in good shape to improve your home's energy efficiency and enhance your HVAC system's performance with newer, more effective materials.

If you’re moving wires, installing new wires, or installing new fixtures in the space you’re insulating, then you will need to hire a licensed electrician to do that portion of the job for you. However, if you just intend on replacing old insulation or adding new insulation over existing insulation, then you don’t need to hire one. Your insulation installer will work around wiring, fixtures, outlets, and switches, even if they’re installing fiberglass batts in the voids where wires run. However, you will need an electrician if you suspect a problem with your wiring during the insulation work.

The life span of fiberglass insulation can be as long as 80 to 100 years, but because of changing building codes, it’s best to get your insulation checked every 10 to 15 years. Signs of degrading fiberglass insulation include bits of batts on the floor or batts detached from frames. Having optimal, healthy insulation in your home will improve its energy efficiency, lowering your monthly bills.

STC (Sound Transmission Class) is a rating that describes how well a building material or assembly blocks airborne sound. A higher STC rating means less noise will pass through the material, providing better sound reduction. This rating system applies to various building components, including windows, doors, flooring, drywall, and insulation.

For context, a typical single-pane window has an STC rating of around 25 (where normal conversations are audible), while a well-sealed, double-pane window can exceed STC 45 (blocking loud speech and most music). It is important to note that for some products, like soundproofing drywall, the STC rating refers to the entire wall system, not just the individual panel.

Additionally, STC ratings are most effective for measuring sound reduction at mid-to-high frequencies, such as human speech, and may not accurately reflect how well a material blocks low-frequency sounds like bass music or thunder. Because of these factors, it is recommended to consult a professional to determine the right STC-rated materials for your specific soundproofing needs.

The life span of insulation is between 20 and 100 years. At that time, existing insulation can fall victim to gravity, resulting in compression, which reduces its insulating protection or R-value. If you can't simply add more insulation over the existing material, removing the old to increase the effectiveness of the new can reduce your energy bills and make the project worth the time and money investment.
