"We needed retrofit wall insulation and after checking around all the listings through AngiesList, Yelp, and others, we found that only Bay Valley and SDI does retrofit wall insulation work. We went with Bay Valley because the price was reasonable and they responded quickly and promptly (can't say this about SDI*). Joel was our estimator and he came out promptly at the time and date indicated. He was thorough and thoughtful on how he approached the job, not overselling or recommending things we didn't need. We live in an older house and he appreciated the home and looked for the most non-invasive method to take care of our un-insulated exterior walls. Bay Valley's approach is to come in from the exterior walls with the typical 2-hole process (high/low) to blow in the cellulose insulation. They sent two guys in and despite a couple snags in the job, they finished the job in one full day. Afterwards, they plugged the holes, textured and primed, and the next day came in to paint (our-supplied) paint. I was really amazed how well and seamless it all looked afterwards. They did a good job cleaning and even moved the cabinets in the garage back where they originally were. The real result? The mornings have been a little bit warmer than last week, but so far the heater has barely turned on over the past couple days. The house already feels warmed and less temperature fluctuations. We already got brand-new attic insulation last Fall, but the wall insulation really did the trick. A definite recommend to anyone who needs a good team to do insulation in their home. * dealing with SDI was a nightmare, unfortunately. With *several* calls about being in the ER, then lots of other excuses, it just didn't seem like they wanted to do the job or something. I originally made the request in August and this morning on Nov 10, I got a phone call inquiring if we still needed insulation done. sigh."

"I hired Bay Valley to clean out one attic and blow in insulation to the two attics in my home. Joel came out and did a thorough inspection, explaining everything as he went along. the quote was reasonable and fair. Unfortunately, on the scheduled day the team was overbooked and although I had taken the day off, by the afternoon it was clear they would not have time to do my job. Knowing I was disappointed , they agreed to come the next day, which was Saturday even though they don't work Saturdays. Tony and Henry arrived in the afternoon and worked literally non-stop for hours until they got the job done. They were as clean as such a job allows for and when they left the debris was gone. I would recommend Bay Valley Insulation to anyone but I would also be sure everyone was in sync on the schedule."

"I love this company! Garrett came to my home and assessed how efficient our current insulation, etc was. He was very informative and friendly — explained what we needed and how they could help. At the time, I decided to hold off and he never pushed the sale. When I was ready, he was quick to accommodate my schedule. His team: Angel, Luis, Tommy and TJ were great! They arrived early, were professional, courteous, kind, very helpful with my questions and were above and beyond to help fix things that I wasn’t even aware of. They also were more than happy to help with small problems that I had no idea how to fix. They worked quickly and cleaned up afterwards. You could tell they cared about their work which makes me feel confident that the job was done right. They were also fun to have around — my Great Dane loved them too! Garrett and Dave checked in with me during and afterwards to make sure things were going well and if I had any questions. I highly recommend Eagle Shield."

Insulation questions, answered by experts

While insulation is required for all exterior walls in a house, it is not typically required for interior walls. Local and state building codes mandate that new construction homes have adequate insulation in exterior walls and ceilings to suit the local climate.

However, there are several benefits to adding insulation to interior walls. It is excellent for sound-dampening between rooms and can help with temperature control by maintaining a regulated temperature in specific rooms and lowering heat transfer between adjacent areas. Insulating interior walls can also contribute to the overall energy efficiency of your home.

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.

According to a report from Energy.gov, radiant barrier installations can save between 5% and 10% on your energy bill each month that your HVAC cooling is in operation. That fact can mean savings of up to more than $325 per year for homes that experience frequent direct sunlight and high summer temperatures. 

The ideal temperature for your garage in the winter is between 40 and 68 degrees Fahrenheit. Maintaining a minimum temperature of at least 40 to 50 degrees is crucial to prevent pipes, liquids, and other items from freezing. Low temperatures can also drain your car battery, so keeping the garage stable is vital for your vehicle. While the lower end of the range protects your belongings, the higher end is based on your personal preference for a comfortable space. If you struggle to keep the temperature from dropping below 40 degrees, consider installing a garage heater.

The lifespan of insulation depends on the material type. Fiberglass can last between 80 and 100 years, but it is important to start checking it around the 15-year mark. Spray foam has a lifespan of up to 100 years, and mineral wool can last up to 100 years. Cellulose, an eco-friendly option, has a lifespan of 20 to 30 years.
