Great response and great customer service from beginning to end in all aspects of the work. Daniel and crew were skilled and friendly. Everyone liked their work, supportive of each other and if me the customer. Very refreshing to experience this.
I am so impressed with this company. From start to finish, every point of contact was professional and thorough. Customer service and follow-up is excellent. The work was completed on budget and on time and every single person I had any contact with was knowledgeable, polite and competent. I would never hesitate to recommend them!
Clean CrawlSpace is definitely the right choice for the work to be done. Diego and Dave replaced a sump pump, did extensive drainage drilling and installed a much needed moisture barrier under the house. They did it in the time anticipated and they cleaned up at the end of each day, a very important service expectation of mine. Thank you.

Insulation Solutions arrived on time, accompanied by three professional, courteous, and attentive workers who genuinely cared about my satisfaction. They meticulously taped off my garage and left the area in pristine condition, as if they had never been there. The service was exceptional, and the pricing was competitive and fair. I express my sincere gratitude to Gabriel for delivering an outstanding job.
This is my first time needing help installing floors. The last crew I hired wasn't this fast or affordable. And when I called, everybody I came in contact with was nice and patient. I felt like an actual valued customer. If I had to call then again, I wouldn't even hesitate.
Hands down, the best installers I've ever hired so far. I needed assistance with drywall and also in my bathroom. After a quick conversation, they handled the situations like professionals. I am truly thankful.

I recently had Atticare come out to clean and insulate both my attic and crawlspace, and I can’t say enough good things about the experience! Sean was my technician — super friendly, on time, and clearly knew his stuff. He showed me photos before and after, explained everything in plain English, and made sure I understood exactly what was being done.
I recently had Atticare come out to my house last year to remove old insulation and then lay down new insulation along with rodent proofing the attic. A little over a year later Rats were still getting into my Attic and even though my warranty had expired Attic care was nice enough to send out their engineer Kyle to address the issue. Kyle spent several hours at my house today to do a thorough inspection and rodent proofing of any access areas were the rats might be getting into my attic. Kyle also repaired my air ducts the rats were chewing, cleaned up the attic of any droppings and completely sanitized. Very happy with the follow up work Kyle was able to complete today.
I recently used Atticare for my home in Pasadena, and I can honestly say it was one of the best home service experiences I’ve ever had. The team showed up right on time, explained the process in detail, and got to work right away. They removed the old insulation, cleaned and sanitized the attic, and installed fresh insulation that made my home feel instantly more comfortable. What impressed me most was how thorough and professional they were. They didn’t just do the job—they also sealed entry points and made sure my attic was protected for the long term. It’s such a relief to know my home is cleaner, safer, and more energy efficient. I highly recommend Atticare 5 stars all the way!

Miquan and his crew were a delight to work with. They were knowledgeable and completed the work in a very professional manner. Their quote was very competitive and they delivered exactly what they promised. Anyone considering re-insulation should jump at the chance to use there services. I am a very happy customer.
My husband and I are impressed with their responsiveness to all my questions and quality of their work. We did not have insulation in the house and needed it installed asap in our exterior walls due to miserable overheating in the house. They took good precautions to cover the floors and furniture, took their time to do the job right, finished everything in the estimated time frame, and took care when cleaning up. They just left and we already feel the difference in temperature. We are very happy and totally recommend this company!
Excellent work by Miquan and his team! They completed attic insulation, spray foam for my loft, and full duct replacement. Miquan was very knowledgeable, took time to explain what my house needed, and was always prompt with responses. The team was extremely professional throughout the project - respectful of my home, arrived on time, and maintained a clean work area. They actually finished the job ahead of the promised timeline, which was a pleasant surprise. Quality workmanship throughout and I’m already seeing improved comfort and energy efficiency. Highly recommend for insulation and ductwork services.

We asked for the job to be done in june. I called last week to see if we could do it sooner and we were able to have it done yesterday. They were in and out in 4 hours. Covered everything. Cleaned up. The owner was here working with a crew of 2. They started in the master bedroom and compared to the day before when it was hot in the afternoon we could already feel a big difference. We cannot wait for winter to see the difference and i can finally put my furniture along the exterior walls
Great to work work with, completed the job quicker than expected.

I have had ALCAL replace my garage doors and clean and replace my attic insulation. Rich and Tim came out to provide estimates for both projects and were very professional, and answered all of my questions. Their crews were on time, very polite, clean, and did great work. One of the insulated garage door panels was cracked and they coordinated with the manufacture to get it replaced. I also was extremely pleased with how well they cleaned out the attic in preparation for the new insulation-thanks Rafael, Dillon, and the rest of the team!
The installation gays are always good
