I highly recommend this company! They provided excellent customer service, were helpful, honest, and most importantly they do a great job on the services they offer. I feel like their pricing is very affordable/competitive compared to similar businesses. From beginning to end, they were highly professional and easy to work with. I would call them again for any home issues I have.

 He did a great job. He came in at budget and I have and will hire him again. On time no up selling,

neat and clean job. 

Square 1 did a great job on our newly purchased house, it had rodent damage and was just nasty. I check out the crawl space after it was done and what a difference.
5 stars!!

"In March, 2015, Jon Edward replaced the vapor barrier in our crawlspace, and we were very happy with his work. Before the project, Jon gave us a free estimate on the job and he provided a detailed description of what needed to be done. While in the crawlspace he noticed a drip from one of the pipes, and he took pictures of the problem and then emailed them to us so that we could find a plumber to fix the issue. Jon is hardworking, trustworthy, and is very knowledgeable. We would highly recommend Jon Edward to others looking for a licensed General Contractor who specializes in crawlspace work."

"We used Square 1 Venture Group to clean out our crawl space as well as deal with a rodent problem and we were totally impressed!  Jon was completely professional on the front-end during the bid process, and then when he and his brother showed up for the job, they were always on-time and cleaned up before they left.  I especially liked how, when the scope of the project changed during the job, Jon lowered his bid to reflect the amount of work being done.  Not a lot of contractors would do that. I am so glad we hired these guys.  They worked extremly hard and did a fantastic job.  We are recommending them to all of our friends.  -Andrew S., Sammamish"

Jon does an exception job. He is very careful to explain options and why certain ones would work better than others. I have had him do work at my CPA office in Kent as well. I have recommended him to clients and they have been very well pleased as I and my wife have been. If I have another project I will call him first.

Project: Remodel
Comments: This was a major project that took several months. Jon was a pleasure to work with - always friendly, courteous and professional. I was impressed with his expert knowledge in all phases of construction and project management. Jon is an innovative problem solver and offered creative design ideas that made the remodel unique. I was very pleased with the finished product. Jon provided superior customer service and a high quality remodel. I highly recommend him and will definitely hire him again.

Comments: Joh did excellent work and when he used subs he provided us with a copy of their business license, L&I registration and their bond. He also cleared out crawl space and replaced the insulation and sheeting. He is very meticulous and communicates often during the project with suggestions and status of the project. We would hire him again.

Project: Install or Upgrade Batt, Rolled or Reflective Insulation
Comments: I could not be happier with the work that Square 1 completed on my new cabin. Jon came out the day after I spoke to him for a comprehensive quote for my job and supplied an extremely detailed estimate within 24 hours. Once I decided to schedule the work he was able to confirm the installation in less than one week. 24 hours prior to the scheduled installation time Jon called to confirm the exact start time, Jon and his crew showed up exactly when they said they would and completed the entire job in one day. The work they performed was flawless, everything right down to the cleanup was amazing, the building was actually cleaner when they left than it was when they arrived. I would not hesitate to hire Square 1 again and will most certainly recommend them to any of my friends/family for any projects.

Jon came over to bid our attic for cleaning and new insulation in February, he showed up on time was very nice and pleasant, he gave us his bid on the spot and then we waited for 2 more bids form other contractors. After receiving the other bids we decided to go with Jon. He informed us that he will be onsite for the job, the access was inside our master bedroom closet, we felt comfortable with Jon inside our house while we were at work. The job was completed in 2 days and it was painless for us. Great Job!

Comments: We had originally had him come to do insulation and discovered some structural issues, he was the only one that noticed out of 3 other professionals that came to look at and bid our insulation project. He was diligent in his work and took pictures to show us the crawl space and the damage he was talking about. I would highly recommend him, we were very impressed with his level of professionalism.

Comments: Jon at Square 1 Venture Group LLC. is extremely knowledgeable, works quickly and carefully, is thoroughly professional. I appreciated the bid process. Instead of handing me a pen to sign up on the spot he suggested I get other bids before deciding. I did. Jon's bid was competitive in price with a bid I got from another well known insulation contractor specializing in crawl spaces, but in my view the materials and installation methods were superior. They arrived on schedule early in the morning. As they pulled out the old stuff they checked the entire area for any issues that needed fixing (happily in my case there were none). Dry, no entry points for rodents, no dry rot. Then the new: unfaced fiberglass went up into the floor joists, faced insulation went on the cripple walls, stairway area, and wall transition to slab floor. I especially like the material they used for duct wrapping which combined a tough white plastic exterior, fiberglass insulative layer, and a reflective layer. They sealed all duct air leaks before cutting /wrapping /taping the new stuff on. The result was a clean, thoroughly insulated crawlspace which I'd almost describe as "attractive" (though probably a bit short on headroom for entertainment gatherings). They then cleaned up every trace of debris, even leaving the driveway area leading to their truck cleaner than when they had arrived.

Project: Install or Upgrade Insulation
Comments: I hired Jon to clean out and reinsulate a crawl space of a home I was remodeling to sell. His bid was much more reasonable than several other bids I had received and they got the work done quickly and efficiently. I was so pleased with Square 1 Venture Group I hired them to help out with some additional projects on the remodel and couldn't have been happier with the end result.
