Ricardo is a diligent electrician who genuinely wants to do a good job. He is reasonably priced, knows his stuff and works hard. He is good at planing the times he is available and forecasting how long the project will take. He showed up on time and did the work. At times, you may want to be sure to over earlier specifications when he arrives for the day so there is no miscommunication in what is expected and what will it take to accomplish that. My job was fairly complicated as it involved ceiling, wall, panels and wiring for a variety of devices that are not normally used. I'd hire him again.

Shlomi was amazing. He's very professional and considerate. Him and his crew took care to protect all my floors and walls while doing the work. Shlomi took time to show me what he was doing at every stage of the process. Shlomi made me feel comfortable that the work was being done correctly. I had my attic cleaned, sanitized, rodent proofed, and added all new insulation. He also cleaned all my ducts, vents and HVAC. I would hire him and his team again hands down. They were fantastic!

We recently had our rental apartment insulated by the guys at Home Team Services, I was able to convince my landlord after reading up on the benefits of the spray foam insulation or SPF as they call it, we had been suffering from poor insulation from the 50 year old insulation done in the apartment and the landlord wasn't happy with the energy bills after our repeated complains and him having to keep the heat on all the time. The job was done within the time frame promised and there wasn't any mess left behind, we now have a nice and warm apartment ready for the winters and I'm sure despite the cost our landlord will be happy with the bill savings in the long run, and also with less nagging from tenants.

This was a great hire. We needed an attic cleaned of rodent droppings and reblown with new insulation. Not only they came through in our budget and met our time line they found five access points and sealed our attic. The insulation is treated with orange oil to prevent spiders and such as well. Thanks again for an outstanding job well done. Makes me wonder why other companies do not offer to seal the attics?

Alfredo and his crew did a great job, installing insulation and the plastic membrane which covers it quickly and professionally. They were careful to put foam caulking around all the windows and plumbing passages too. This was a sizeable project: a two-story addition to my house, with some complications like a stairway and skylights to work around. There was a little delay when they ran out of plastic and none was available on a Saturday, but they came back on Monday and stayed until the job was finished, not asking for more money than had been agreed upon. I'd recommend them to any friends of mine contemplating a similar job.

Attic Cat

I hired Attic Cat based on their good online reviews, however I had a bad experience with the workers. - We had a rat issue in the attic. I specifically told the estimator that I want to make sure that all of the rat droppings & rat contaminated particles from the attic get cleaned up and not get into my living space, as I'm pregnant and need to be very safe. I can't believe that the workers left a ton of vacuumed up rat contaminated dust/trash in my front yard! When my dad noticed it and talked to the workers, they promised to clean it up, however later they just hosed it down with water, which made it impossible to remove! - We had a disagreement with the workers about the scope of work around 1pm (we had paid for the rat proofing of the whole house and complete insulation replacement for the whole attic). The workers at the house wanted to check with the lead worker although we showed him the contract. The lead worker left around 11:30 (he said that he was going on a lunch break) and didn't come back until 3pm when the two workers in the house finished everything else. As soon as he came back he wanted us to pay him and leave and he refused to remove the rat contaminated insulation in the garage. We eventually called the estimator and got them to finish the work. - The workers's behavior was very unprofessional. They didn't communicate well. They took down a furnace panel from the attic without telling us, and we found it laying in the backyard and didn't know what happened. They also turned off the furnace without telling us and they didn't turn it back on!!! We found out a week later when we couldn't turn on the heater and it took us a few hours to figure out why. On the day of the work they just entered the house through the unlocked front door. We suddenly saw a few workers working in the house and had to ask them "who are you?? " Yes we left the front door unlocked as we are anticipating them to come, but it didn't mean that they can just enter and start working without confirming with/notifying the owner first! I understand that the workers don't speak much English, which could be a reason why some of those things happened, but they still should have communicated with us somehow. I complained to the estimator on that day, who was very polite and promised to contact the owner of Attic Cat and get back to me, but he never did. Later I called the office to spoke to a lady, who was very apologetic and also promised to contact the owner and get to me and "make it right", but she never got back to me either.

Excellent job for removing old insulations and cleaning up attic ! They are quick, organized, well experienced and super friendly. They are also trustful because they picked up two left over super big bags which filled up with old insulations on the following day for dumping. Everything is done perfectly. They deserved 5 rating stars service. Taking this opportunity, We'd like to say thanks to the guys Jose and his employee. We strongly recommond Qualit Pro Guard. Cherry

CrawlSpace Clean was thorough and professional. We really appreciated the time they took to make sure we understood what needed to be repaired under the house and why. He also sent follow up photos after cleaning up the rodent feces and removing the old insulation. We are extremely happy with their service.

Luis and his team were great. He came on time, was very courteous, and his quote was the best we got of 3 other companies (by far). The best part was he was able to get a crew to do the insulation install the very next day. His crew made sure to use drop cloths and taped off my entire house. Five hours later I have cleaned and rodent sealed attic full of insulation. I am excited to now enjoy summer in my house with insulation, so far this summer has been brutal.

David and his team did a great job in my house! We invited the person from San Mateo County Pest Control Department to inspect our house after the job was done. The guy is very impressed by David’s work for both insulation and rodent prevention!

Unfortunately I was not able to proceed with my insulation project with B Green Service (my HOA did not approve the project). However, I was still very impressed during my time planning and working with Shlomi. He provided a reasonable quote to install blown-in cellulose insulation into my apartment ceiling, and was very professional and transparent with pricing during the process. He was knowledgeable and explained the various types of insulation, and gave a break down of completion timing. Additionally he was very responsive to my emails, texts, and phone calls, and provided all necessary info that I'd requested from him on time. Although I did not have a chance to hire him this time around, I would certainly work with him and his company in the future if given the chance.

Recently I purchased a 2600 square ft. house from 1945. My concern was the high electric bills I was to expect during the winter and high summer temperatures. The staff at Lemon Remodeling was quick to give me an estimate and super fast to execute the job. The walls got pressure-filled, subfloor stops installed and new attic insulation (R49), replacement of thermal windows and door! My house is comfortably fresh, and the street noise is cut down to an absolute minimum. Ask them for your insulation it's the best decision we took! HIGH-QUALITY WORK!
