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 I originally made the request in August and this morning on Nov 10, I got a phone call inquiring if we still needed insulation done.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.

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.

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+

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.

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.

"This consumer mistakenly posted a review intended for a different company working in a different trade (roofing), and so should be removed soon."

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.

Response from Bay Valley Insulation Inc
"Glad to see vent issue was resolved per customer's needs, and appreciate the positive feedback. Mechanical means to prevent eave vents from being blocked by fiberglass blanket insulation are normally not necessary, but can be used at the request of the builder to address unusual venting situations. Inspectors usually want to see blanket insulation installed up to the top plate where eave vents are present, but thin enough to allow air circulation behind the insulation, although historically the practice has often been to simply keep the insulation well back from the eave vents. Installer was sure he followed the correct installation procedure, so without the opportunity to go back and see the work, we can't be certain of an installation error. It is always best to call us anytime with any questions or concerns, so we have the opportunity to promptly address them and make any corrections, if needed."

This project went very well.  The estimator was extremely knowledgeable and was able to walk me through the options, educated me on the rebate process, and gave me a breakdown of the steps in the project.  He was also very careful in his examination of my home noting areas that would need special attention to get the insulation in properly (around my fireplaces).
  The work took two days, as the walls needed to be done(-involves cutting disks out of the existing siding, concrete or drywall of every external facing wall) and blowing in the insulation and then  patching and repainting.  In the attic, they have to make sure that they can blow the insulation over the lighting fixtures and also it can be very tight in some of the spaces that they need to get to.
The team worked extremely hard and with great precision.  I was initially nervous about having disks cut out of the sides of my house and the repainting but these guys are true professionals and you can't see where the work was done.   
The rebate process went really smoothly and I received my rebate in a couple of weeks. 
I am also extremely pleased with the results of having a better insulated home.  It stays much warmer in the winter (spent less on heating during the cold snaps) and so far this spring, have not had to even think about using air conditioning.
The owner also called me to check in on my experience.
Very happy in Saratoga

Most if not all the problems were internally.    First off the second technician, who was the secondary help, was smoking in my garage, which is unacceptable.    In the interior of the house there were at least three holes than were not filled properly, along with an entire wall where the nails had popped out because of insulation. These were not fixed by the technicians where they finished.       In addition there were three hammer indentures that were made in the walls to locate drill holes were not filled in.   
Three holes in the garage also had to be redone.   
The sizes of these holes are 1.5 inch diameter, so they are not small.    
  These issues are fundamental to the craftsmanship; making and patching holes, along with looking for popped nails is not a one time or rare event, this is what these guys do, so having missed something that is so basic is an indication of poor quality. 
Customer service:   
The owner of the company was helpful in trying to fix the mess.  However at first conversation I would have had to wait a week before they came to my house to fix the mess.    So I decided to buy my own compound and patch some of the holes, which I did.  
  Later on that day the owner had a change of heart and sent the second technician back to our house.  This individual did paint the outside, and helped patch the nails.  However we had two sets of paints and he painted the wrong color on an entire wall! All he had to do was look at the other can, or communicate with me, and I was present in the house at the moment.  
  The third time the owner sent over the more sincere technician.  He arrived one hour past the two hour window, and was stuck in evening traffic.  This individual painted the wall and fixed the remaining four holes in the garage (using my material).      Overall impression: There is a clear lack of value either in terms of price or quality of the worked performed.  The technicians missed doing the basic tasks, which is not a good sign.  However the owner was sincere and did send his men, but there was no urgency at his end, they all came when they were available versus trying to fix the job not done well.   
For my part I upheld the entire contract, paid the full agreed upon price despite the poor quality of initial work.   
Given the price and quality of service I would be hesitant to give a good recommendation.

Response from Bay Valley Insulation Inc
"Work on our own repairs, several slightly elevated popped nails and some hammer indentations -items that can be difficult to catch or notice, was fairly minimal and fixed same day as reported by customer, with no prior talk of any delayed scheduling whatsoever. Customer doing some of his own work in advance was not necessary as we prefer fixing our own work. Customer was given prompt, same-day service when he notified us of problem, and workers are sure the few patches in question were damaged after their work, as they take much longer to dry than exterior patches, and call backs on several patches that are simply not done right simply don't happen. The paint was put on some wrong patches on one short exterior wall because worker understood he was instructed to paint them by customer and it was similar to other color, and not yet dried to show it's final color, which may also be why customer provided just one color of paint the day the job was done, and later had to obtain the other color paint. This paint was easily fixed at a time approved by customer. On second call back, the paint repair work only was what was requested by customer, and worker stopped by on his way home from work, and so did not bring along patching materials because customer did not request patch work to be done till after worker arrived. Interior walk-throughs are standard practice when beginning a wall insulation jobs, but not so much at most jobs end due to experience showing a lack of sufficient need. Training on filling walls with insulation is the most intensive part of job training, to ensure a good insulation pack, and is also something a customer doesn't see, so that is where it is most important and a trained worker doing the filling will always be well versed in answering questions with a process that is rather complex to most people. Patching questions are fairly simple to answer by comparison, and patches receive the most attention by customers. Customer reported cost of work was later reduced by about 1/3 from standard PG&E rebates, making the value of such work quite obvious to any homeowner interested in year round comfort and heating and a/c cost savings, not to mention quiet and elimination of mold from some homes where it is an issue, and less drafts. Word of these rebates should get around because they may not be available after end of this year."

The company was extremely responsive to my email request for information and set a date for 1/31; however, they had a cancellation much earlier in the month. They called and arranged to be at my house at 4:00 p.m. (incredible to be able to begin a job like this after my work ends). Unfortunately, the installers were tied up on another job. They called and asked if they could come later. I said definitely. They finally arrived at 6 p.m. and still did all the work. They went above and beyond to keep the house clean and were extremely accommodating. The insulation made an immediate difference. This was a great company and a great crew!

Joel came out to give us an estimate to insulate our 2100 sq foot, two story home.  He arrived right on time and was very professional.  He checked our attic and found that we had only R11 when R38 is recommended for our area. Additionally, we had no insulation in our exterior walls.  He wrote up a very detailed estimate and explained the proceedure thoroughly.  He provided two separate quotes for the walls and attic and included the PG&E rebate for each.  After receiving a few other quotes, we decided to go with Bay Insulation.  They were able to make an appointment within a weeks time.  The installers were about an 90 minutes late on the first day, and I had to call to find out if everything was still on schedule.  When they did arrive, they got right to work.  They did almost all the walls on the first day and did a very thorough job.  They cleaned up everything even though they were coming back the next day to finish the attic. Overall the installers were very professional and worked very hard.  Only two guys did the entire job in two days.  They were very professional and did a great job and did more than I expected.  My only complaint is that they arrived late on the first day without a phone call.  But they still completed the job in the estimated time and did a great job.

12/29/10 Bay Valley Insulation sent over provided an estimate to insulate the outside walls of the home. I accepted their bid and set Thursday 1/13/11 to complete the installation. I received a call from Bay Valley Insulation Tuesday evening 1/11 requesting to re-schedule due work backup caused by bad weather. We re-scheduled for Saturday 1/15/11. They would be on site between 11am and 1pm. Received a phone call Saturday at 1:30 saying they were running behind schedule and would should be there in about 1hr (2:30pm). They arrived at 3:15pm. Once on site they explained why they were late, looked over the project then immediately began work. The the job was finished at 7:15pm. I observed them while they worked, they worked efficiently and took pride in their quality of work. They did a great job cleaning up after finishing the job.. I'd love to give them an A+ but because they failed to properly estimate the time they would be there and not re-contacting us to notify us they would be later than expected I rate them A-.
