Spray Foam Insulation in Santa Clara, CA

Working with Greenshield was a great experience from start to finish. Booking the attic insulation was straightforward, and the pricing was great. The installers were courteous, organized, and respectful of my home, which made a big difference to me. After seeing the results, I hired them again a few months later to insulate the exterior and interior walls for sound control. The improvement was immediate — noise from the other bedrooms is no longer an issue like it was before. On top of that, my heating costs have dropped noticeably since the work was completed. I honestly wish I had done this sooner. I’m going to recommend this company to my friends and family.

Greenshield deserves 5 stars. 1. They are very flexible to work with. 2. Sounds professional throughout the project. 3. Keep up to their promise. 4. Workmanship is excellent: I replace my attic insulation and air duct system to help me with my allergy problem (I remove insulation, next install new HVAC system, finally install insulation. I have abestos removal, so this is the best sequence for me.) - They clean very well. Using negative pressure vacuum, they suck and remove all the junk, blown in, batt and left nothing behind. I personally went up to inspect their cleaning after they were done. (I pay extra attention to the cleaning process because I don’t like the musty smell of an old house. I have allergy, so air quality is important to me. They also sprayed to disinfect the attic.) - Installation is very good. They put back brand new thick R38 insulation beautifully. They reach even the furthest corner. Every part of the attic is covered. 5. They stand behind their work. I am glad to deal with Greenshield. I have no headache or hiccup in the entire process. As a regular home owner, I have zero knowledge prior to this. 6. They have rebates, so at the end their price is competitive. They do all the rebate for me. I shop at many other places and finally decided to go with Greenshield. My recommendation just go through Greenshield in the first place and save your time. They give you the price upfront and no need for negotiation like other contractors/company.) Due to the rebate, there will be an inspector from CA Energy Program coming to inspect to make sure it is done correctly and up to code. ( I have a piece of mind knowing their work has QA from a government agency.) 8. Usually old house has aging sheetrock and especially in bathroom due to moistures build up over time. It is very easy to crack/break sheetrock and to be fallen off from the ceiling. You don’t want to hire a handyman or no name contractor doing this job. Finally, the biggest win here is you don’t have headache dealing with contractors, and you know you can trust them to install insulation with good workmanship and use quality material. P/S: Greenshield did all the rebate application for me. Inspector came 3 days they finished the job. My rebate was approved within a week after the insulation. I was surprised how quick and easy the rebate process was.

I'm pretty happy with the insulation work. The room above my garage had cold floors so Greenshield punched holes on the garage ceiling drywall, blew in several bags full, and patched up the holes and cleaned up everything afterwards. They showed up on time, did very clean work, was very professional and most importantly the outcome was great. The room floor is no longer cold and the house is better insulated than before. The price was very competitive and they knew exactly what to do. Highly recommended.

Jorge and team were exceptional to work with. The removed our old insulation, sealed the attic and added new fiberglass insulation, explained each and every step and went great lengths to do rodent proofing. And all it took was few hours. Jorge also came few months later to fix some of the gaps that the HVAC crew left in our attic. I highly recommend Ideal Attic for your insulation needs. Their price was the lowest as well among all other quotes.

I feel very fortunate to have found Ideal Attic Insulation to work on the attic and crawlspace of our newly purchased home. From the start, Jorge came to provide a free inspection, and he was extremely professional and thorough. He personally went into the attic and crawled into the crawlspace to check every detail. After his inspection, he gave us a very fair estimate with a clearly written and complete scope of work. We also requested quotes from other companies, but it became clear that Ideal Attic Insulation—and especially Jorge—was the most professional, responsible, and knowledgeable. Jorge even helped us connect with other reliable handymen for additional repairs we needed around the house, which we truly appreciated. Once our plumbing repairs were completed, we scheduled the attic and crawlspace work. Jorge’s team handled the attic cleaning, sealing, rodent-proofing and new insulation installation. In the crawlspace, they performed a full cleaning, rodent-proofing, and installed a new vapor barrier. The scheduling was quick, and everything was completed within three days. The workmanship was excellent—clean, organized, and very professional. We really trust Jorge and appreciate his honesty, experience, and dedication. I highly recommend Ideal Attic Insulation to anyone looking for attic or crawlspace services. We will definitely continue using this company in the future. Highly recommended!

Jorge is the best. My wife and I had contacted 4 companies, and by far Ideal Attic Insulation was the winner. With us it wasn't all about price, but quality, knowledge of the trade and experience. We had our old insulation removed when we replaced our roof. Yes, like lot of us when your roof is compromised you have issues with rodents. Once our roof was completed, we set our appointment with Jorge. He came out the following afternoon, and boy was it hot. He inspected our entire attic and came up with a game plan to vacuum and sanitizing our entire attic space. He took a lot of pictures and shared areas of concern with us. We had the roofer's comeback out and tighten up area that may have been able to be compromised. once these areas were tightened up Jorge sent out his crew to install mess wire and stray foam around vent pipes, etc. Jorges recommended we wait a few weeks to install the insulation to see if there were any signs of rodents. After a few weeks and weekly inspections by Jorge and his crew, there were no signs of pests. They installed the insulation, and we could not be happier. We highly recommend Ideal Attic Insulation. Don't waste your time looking for other insulation companies call ideal Attic Insulation and know you made the right decision.

Chad and his crew were fantastic from start to finish. The crew were fast and left our job site clean. Everyone from Sanden was professional and knowledgeable and able to answer all my questions. I would highly recommend them and will hire them again for future projects!

The crew was friendly and worked long hours to get the job done on time. The product delivered is great. I will use Sanden again on my next project.

I've been a licensed gen'l contractor in CA for 40 years, recently moved to northeastern CA, and hired Chad Sanden of Sanden Insulation to fully spray-foam insulate a 2-story project residence. Totally professional operation! Excellent price and product, hard workers, project done on time, and they left the place cleaner than they found it---how often do you see this kind of operation these days? Honestly, they don't get any better than these guys!

As a contractor you're always looking for the best supplier of insulation, someone who can provide you with competitive prices, hardwood and quality. Vortex insulation is the best option! Their office manager Mike made everything so easy and the owner Luis and his team installed it all right away and perfect. These guys are the best insulation company in the whole Bay Area!

These guys are the best! Extremely quick service and a true dedication to their customers. I had a complicated request about exposed beams and they worked nights and weekends to make my vision come to life and stick to their original date. Would recommend them 5,000%. Great value, great quality, great service!

We hired Vortex for a ceiling and wall insulation. The service provided by Vortex was excellent, fast and their employees were very respectful and professional. Price was very reasonable. We recommend this company for any insulation needs. Overall experience was good. Customer service at all levels was excellent. We give this company 10 plus stars.

Roof coating : From start to finish ,Job was outstanding : We have had so many complaints about the roof, could not fault them & would highly recommend them. Price - Quality= superb

This company has great tenacity and work ethic I would 100% refer someone to their services as they are the best in the industry. Don’t look any further, go with Eagle Insulation they will take care of you.

The very best experience, friendly staff , excellent service,highly recommend.

Thank you the insulation is amazing great job guys

Tri county did wall insulation a few years ago, which made my home warmer in the winter. The wall also patched well after the blow in, even though it is outside wall. The price was the most reasonable one. One bonus I got is the worker patched the hole in attic for the rodent not to enter. I recommend this company for pricing, quality of job and service.

Excellent, professional, and very knowledgeable contractors and crew. I got multiple bids and Tri-County was competitive, but not the lowest. It was absolutely worth paying a few dollars more for the confidence and honesty I got with Tri-County. They scheduled my job realistically and worked with me when there were delays. In and out in a timely and reliable manner. Highest recommendation!

We had insulation put in under the house and in the walls. It was a big project and took 2.5 days. These guys came in and were so professional, knowledgeable and respectful. They never complained even when presented with obstacles. Hands down some of the best people we’ve worked with during the last several years of renovations. They even took time out to chat with my nosy kids. My daughter loves to say that Pedro is her new friend! Thank you!!
