Love the Attic Crew! 2 shout-out’s: First, Ron and his team came out and worked their asses off for 2 days, removing a bunch of old insulation and reprise from both our attic and crawl space and doing a bang up job re insulating and moisture barrier-ing and putting out traps for our rodents. Before that, the crew had put together a thorough estimate and inspection with detailed photos. Very thorough and efficient and easy to work with. Second, about a month later, Jose from the crew came out and did a re-inspection to make sure everything was tip top and to make sure there was no rodent activity. Jose took lots of pics and was very efficient/easy to work with. Great team, Attic Crew!
We had a stellar experience with Attic Crew. The estimator was professional, straightforward, and respectful. The work was scheduled promptly and Eric S and his crew were fantastic. They arrived on time, worked incredibly hard all day, and got a complete attic and crawl space overhaul done in one day. Part of the house was left even cleaner than they found it. There’s a reason for all the positive reviews. In a time where so many businesses might let you down, Attic Crew exceeds expectations.
Attic crew has done a terrific job with our crawl space project. The crew is very professional. Kept us informed, provided photos, scheduled a follow up inspection which verified work performed is holding up well. Jose, did a great job! He was professional, informative, provided photos. Very happy with Attic Crew!
Attic Crew has been great to work with from day 1. Daniel was very helpful during the initial consultation. Angie from the office was very communicative. Our attic needed a lot of cleanup plus new insulation and they sent an adequate crew so as to get it all done in one day. Jose did our follow up pest inspection today and he was quick and friendly. We were really concerned about the mold issue and the results of the cleanup are holding up great. There was some accidental damage caused during our install. Mistakes happen. What set Attic Crew apart was that they were totally transparent about the mistake and took full responsibility for the needed repair, which turned out great. Will definitely call them again if we need work in future.
I recently had new insulation installed by Attic Crew, and I couldn’t be more satisfied with the experience. The project was led by Ricky Sanchez, who was professional, knowledgeable, and attentive throughout the entire process. He and his crew worked efficiently, kept the space clean, and made sure everything was done to a high standard. Ricky took the time to explain each step, answered all my questions patiently, and ensured the job was completed on time. I highly recommend Attic Crew—and especially Ricky’s team—for anyone looking for reliable, quality insulation work.
What a difference 2 days make! Our crawlspace started with a little bit of cheapo plastic and water puddles. Tony and his crew showed up and now we have wall-to-wall 10 mil vapor barrier, a French drain system, sump pump, and insulation below the sub-flooring. For the first time, we're not dreading the March and April rains. When you are ready to get your crawlspace done the right way, I absolutely recommend Attic crew.
