Happy with everything from start to finish. Quality work and great customer service including filing for the California rebates!

Tony and Henry both We're very professional they introduce themselves to everyone in my family they asked us to show them where to start after they assess but the situation they started promptly we are very pleased with their work

I didn't write down his name, but the person I spoke with on the phone gave me good advice on what to check for to see if there was anything amiss. He didn't offer to come over (their office is not close to my house) but I felt his approach was very reasonable and it was helpful.

The guy checked my house, told us our insulation is good enough and we don't really need to do anything. Thanks for the honesty. I will definitely recommend this guy to my friends.

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.

Joel came and did an estimate for us today. I found him to be extremely knowledgeable and delightfully honest. I previously had another company come out and give me an estimate. That company wanted to charge ~$4,000 to remove existing attic insulation and add R38. They also wanted to charge ~$3,000 to add wall insulation. Joel inspected my attic and told me the insulation was actually R30 already and looked to be in good condition. He didn't recommend adding any more. Joel also inspected the walls and it turns out it already had insulation in them. THANK YOU Joel for being so honest and saving us a ton of money! I would highly recommend him (and Bay Valley Insulation) to everyone I know and to others on Yelp. Also, he did write us a very reasonable estimate to boost our insulation to R48 if we wanted to go the extra mile.

The work was well done in a timely way. There was a heat wave after the insulation work, and we immediately felt the wonderful difference the insulation work brought. Definitely worth the money and effort!

On time, quality of work was outstanding. When work was done, couldn't tell that there had been holes punched all around the house.

I thought Joel the guy that gave the estimate was nice and educated on the work to give an accurate estimate of the job.  Scheduling took a little time because they are busy.  Guy, the owner, insists that his customers be satisfied. His workers first came in the pouring rain so the paint job was not done great and insulation was left around the house.  Guy assured me the insulation was not dangerous but had his workers come back first to fix the paint job then again to clean up better when I felt there was too much insulation left around the house.  Also paint was spilled on our drive-way so they fixed that issue.  The workers get very dirty with their shoes so I would recommend asking them to remove their shoes if you have concerns about dirt in your house.

Insulating the exterior walls of our two story, 1700 sq ft house, involved drilling holes between each stud, blowing in insulating material, plugging the holes, spackling over the holes, priming and finally painting the holes.  Two man crew was very efficient in setting up scaffolding and then doing the work described.  We got a chance to see what the insulation looks like inside the wall when the force of the insulation popped out a built-in bookcase that was not secured.  Its a solid blanket of insulation, filling in the entire space.   Very impressive.  The results have been very noticeable.  The house feels more comfortable, and the heater turns on less frequently.  We should have done this years ago. 

Last part of the project was to blow additional insulation into the attic, which went very quickly.  Overall, the project took 2 very long afternoons/evenings to complete.  It makes a mess around the outside of the house, but they did a good job of cleaning up each day.

Sales guy was prompt, friendly, thorough and explained quote in clear, easy to understand language. Installers were a little late on the 2 hour  time window promised, but once here,  were friendly, efficient, thorough and cleaned up nicely. I would recommend the firm.

Polite, courteous, punctual.  Did a good job and left no mess.  Repaired the holes that were drilled well enough that they are very hard to spot. House is warm and quiet!

Joe came in at appointed time and was very courteous and honest. He inspected my home built in 1961 and said there is enough insulation in attic and ducting. He also checked if our header is clean. He was very honest and did not try to sell anything that is not needed. I will definitely use BayValley Insulation in future as need arises.

This is my second time using Bay Valley.    They did an excellent job and their attention to detail is great.  They even left me some extra insulation to fill in some voids behind low voltage (TV, cat5) boxes/ wall plates once I wire them up.  
I will be using them again in the future when I insulate and add drywall into the garage.
Great team and very responsive.  The office was able to accommodate my drifting schedule with no problems.
The difference in the house temperature was noticeable immediately.   The interior of the house is much more stable in temperature over the course of the day.  The  new  insulation is doing its job great and should pay for itself quickly in lower utility bills.
A+

The guy I spoke to was professional and did return my call promptly however he sounded as if he just didn't want the job since it's a condo.  I explained that the upstairs carries a lot of heat in summer and colder in winter so we are interested in blown-in insulation.  He stated that no amount of insulation would make a difference in the temperature - this makes no sense to me whatsoever.  Isn't the point of having a well insulated house is to  maintain an even temperature? He just kept saying 'I'm 90% sure that your condo is up to code for when they were built in 1980'.  Great, I'm sure it was up to code but now the insulation needs upgrading.  He basically was uninterested in the job and instead suggested getting air conditioning.

They did a great job in patching the outside stucco where they had to blow it in. It was a good value for the money. They also assisted me in getting all available rebates.

Estimator was prompt and professional. After reviewing our existing insulation, it was determined it was 'near perfect' and the provided suggested not to add anything (as it wouldn't make any noticeable difference).  I appreciate a company's honesty.

First pass they were unable to properly blend existing roof line with new roof line. This was partly because of the framing discrepancies but they initially assured me that they can take care of it. When I called back, they were first reluctant to fix the problem but after some back and forth they agreed to fix it only after I committed to properly shim the roof line connection. Once I shimmed, they redid the work and the results were as expected. Bottom line, if you have an unusual situation, make sure you oversee the progress, but they are pretty fast and professional with routine roof work.

The estimator came in the previous day and checked out the whole house. I was thinking of insulating the crawl space as the floors were cold in the morning. The estimator said the first steps would be to check attic and wall insulation and if that didn't take care of it. then they would insulate the crawl space. He took a look around and said only attic insulation was needed at this time since walls were fine. He also said that if floors were still cold after the attic insulation, they would come back and do the crawl space as well. I called them later in the day and asked them to go ahead with the insulation. I left a message and promptly received a call back and they scheduled service for the very next day. The price quoted was also much cheaper than a previous quote I received. They came in to do the job and cleaned up after themselves. All in all, I am very satisfied with the service and will use them again if needed.

The Good:
Pretty good experience all around.  The crew was a bit late, but they did call well in advance and let me know.    No problems there.
The 2 man crew was polite and did clean up the job site when they were done.  The insulation was installed properly for the most part. (see below)
The Bad:
My only real complaint was that they buried 4 attic vents in the insulation. I  was able to easily remove the pieces that were blocking the vents. I didn't specially say to NOT block the vents, but I would assume an insulation company would know to not do this.  Easy fix, so I'm not too upset about it.
Overall:
Very good price, availability was quick, and the installers were easy to work with and didn't leave a mess.
I would definitely use them again, but would suggest if you do, to make sure you mark and/or double check your attic vents before they leave.  My room didn't have drywall put in yet, so this was easy for me to fix.  Alternatively, install the vent protector metal or plastic "ducts" first.
