Constraction reviews in Santa Clara, California

I worked with Ahmad and team to have some extra insulation done in my attic and a full insulation in my crawl space and Garage. They are very professional in their commitment and have done an excellent job. I would definitely recommend Greenshield for all Insulation needs.

I had Greenshield come out about 3 weeks ago to compete the insulation for my home.

Prior to the work, I had 5 total companies come out to give me an estimate. I ultimately chose to go with Greenshield because of the professionalism and overall Experience during the estimate process.

I chose to have my attic insulation removed and replaced. Along with my walls having insulation blown into them.

He assured me the entire process would take only 2 days.

On the first day, they came and cleaned the attic up pretty quickly. And day 2 they came and insulated the attic and walls.
The crew was polite and very efficient with their work and finished up the work faster than the estimated times.

Overall experience was great with both ahmad during the estimate and the crew during the installation process.
After 3 weeks of having the new insulation I can definitely say it’s made a big difference in the homes comfort.

I will recommend Greenshield to family and friends and rate their service as a 5 star.

From Day 1, I met with Ahmad and he is very friendly and professional. Ahmad introduced the service in details, and started the process very smoothly. The working crew has been doing an excellent job, and I am happily continuing to work with the Greenshield team for the rest of my house. I strongly recommend Greenshield to do insulation work.

Great customer services super clean work grateful for the wonderful work the crow did.
Owner very professional great pricing appreciate all the effort to make sure work was done is timely manner thank you green shield .

My home had a vast temperature swings and the HVAC was under load to keep up. So I decided to upgrade our attic insulation and also install wall insulation for our home. I took quotes from 3-4 companies and Greenshield prices were very competitive. They did not overcharge and not one of those greedy companies who charge their customers for their high overhead costs.
Ahmad was extremely easy to work with, straightforward, cooperative, kind and provides great customer service.

The installation went well, quality work, they patched up pretty good too.
I can make out a significant difference in the temperature inside the home now. Totally worth it and I guess I should have done this sooner.
I am eager to see my next PG&E bill for some savings.

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.

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.

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.

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.
