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.

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.

I had Greenshield do R-44 blown-in insulation on my attic after getting a heat-pump HVAC installed (by a different contractor). It takes a couple of hours and they have several people working on a single house at one time. All of them, especially Ahmad and Dave were very professional. They prep your place and clean up after also. They have the process down pat and it seems like they've been doing this for a long time. This appears to be confirmed by their years in service in the bay area. They are also in contact with BayREN which provides Bay area rebates for green improvements to your home. R44 is the minimum required to qualify for the BayREN incentive. They handle the inspection and submitting of this rebate and all you have to do is wait for your check back. The price is reasonable and the work is definitely high quality. Because we have a newly installed heat pump with a smart thermostat we can quantitatively say that the R-44 blown in insulation makes a measurable difference into how much our heating system is running. I'm looking forward to seeing if there are improvements for the AC during summer as well. The insulation is definitely worth it for saving a few extra kwh if you have a heat pump. I assume a similar effect will be observed if you are using natural gas. If you are considering some energy efficiency improvements to your house (esp. considering the absolute massacre that PG&E is putting us through), attic insulation is one of the best bang for your buck projects you can do. It's also the most minimally disrupting. Plan for a couple of hours and have space available for them to move around and you should be good. Ahmad is very knowledgeable and very accommodating to any requests you might have. I recommend at least calling him to gain some of his perspectives in your next home improvement project. I added a photo of one area that they added insulation in. The white rectangles are how they measure the height of the blown in insulation. I confirm that at the minimum they reach the required level and in some areas exceed the thickness they promised. They also use spray insulation in some other gaps in our attic.

Wow. It's freaking huge. They rent tractors, trailers, construction equipment, hand tools, they sell building supplies, they usually have good inventories and huge selection and for the most part their prices are better than home Depot. Geared more for a contractor, if you know what you want, this is the right store. Impressed with the logical way the stores, shelves and displays are setup, stocked and maintained. Great price on paint. HD carries a lot of things home Depot does not have. I'll come here before Home Depot, in filling the items at home Depot I cannot find at HD supply.

It is big and many selections on a certain things like doors, windows, sinks, molding, flooring, and some others stuffs. It doesn't have many things like at Home Depot or Lowe's. Not many people work here so you have to wait little long for help.

No frills, and limited choices, but carries the same stuff as the other big box home stores like Home Depot or Lowe’s. It is actually kind of nice; they have what you need, but not 80+ different varieties.
