David evaluated our property in July after we had received several conflicting advice and heavy sales pitches from other providers. Unlike the rest, David focused on finding the right solution rather than making a quick sale. He gave us proactive steps to take immediately and clear indicators of when we might need further work done. I thoroughly appreciated his expertise and transparency, and Deska will be our first choice for any future waterproofing work.

Even though their price was a bit higher than the company my agent recommended, I decided to go with them -- after all, buying a house only happens a few times in a lifetime, and you want true professionals for something that important. Looking back, it was absolutely the best decision. Jay did my inspection and was extremely thorough and professional. A few months later, I had a question and reached out to Ian -- that's when I truly understood why everyone gives them five stars. He provided excellent customer service, stood by their work, and was very responsive and helpful. Overall, this is a great company with outstanding customer service. Highly recommended!

The photos speak for themselves--and I promise the bathroom is even more beautiful in person! It has truly been a pleasure working with Azzam and his crew. Azzam is extremely fair and reasonable with his pricing, and most importantly, he always comes through for us. He genuinely cares about getting the job done right and making sure you're happy with the finished product. I've worked with multiple contractors over the past year on all different types of projects as part of our entire home renovation, and I've enjoyed working with Azzam and Triple J Consulting the most. I really appreciate the pride he takes in his work, the value he provides, and the effort he puts into making sure his clients are genuinely happy with the end result.

The owner, Azzam, was great: Highly knowledgeable, very informative, clearly experienced, and balanced in his evaluations of things that were of concern, versus those that weren't. He gave us some valuable recommendations for things to do to double-check going forward that a foundation crack is not a posing a structural risk. In a room that had some unevenness to it that looked like the building could be sagging, he could see that, no, there was a small bulge in the floor due to uneven support beneath it when it was installed. We called with a follow-up question relating to something unexpected a contractor was doing, and he gave us an incredibly helpful second opinion. It was great dealing with him, he was highly professional, and we'd strongly recommend him.

We were purchasing a home and during the inspection a very expensive structural issue was…read morediscovered. The seller agreed to fix and hire a licensed contractor for the repairs. 6 Days before closing the seller's contractor performs the repairs. I arrive at the job site 90 minutes after scheduled start to review the progress and no one is at the site. To my surprised, there are a few cosmetic repairs to hide the damage and other locations no work was even performed. I took pictures, a video and contacted my agent to ask what's going on. Late that evening I'm informed the seller and their contractor are saying all repairs are complete. 5 Days before closing, I'm scrambling for an experienced and licensed structural engineer to review the work performed and advise if repairs resolved structural issue. After spending half a day googling, researching reviews and calling engineers, I come across Bob. Bob was already booked out till mid afternoon Friday (We are closing Monday). So I schedule an appointment. Thursday morning, I reach out to Bob to see to see if there was anyway possible, if he could squeeze us in today. Lucky for us he had a cancellation and was able to make it out early afternoon. Bob arrived a few minutes ahead of schedule and had a very professional demeanor. Our agent and the sellers agent was on-site while Bob performed the inspection and handled the bombardment of questions from the seller agent like an experienced pro. Bob quickly assessed that the repairs were cosmetic and did not resolve the structural issue. He was able to communicate in common language what was needed to properly repair the problem and provided a written report a couple days later. From start to finish our experience with Bob has been fantastic and would highly recommend. FYI: The bids coming from qualified contractors to repair the structural problems are exceeding 20k. Thank you Bob for saving us from a nightmare.

Bitarchitects provided a prompt response, prompt call phone consultation & next steps. Within 1 week of contact I was able to discuss my concerns, the engineer completed a thorough walk through of my home & gave me ample amount of time view discuss my concerns. More importantly they didn't drag out the walkthrough for hours!! I appreciate the honest responses to help distinguish between normal settlement & items that are concerning. I'm waiting on the written report (inspection was completed one business day before writing this review) to proceed with the fixes. I strongly urge spending time & money on an inspection from a structural engineer before spending $$$$ for repairs that aren't needed. Prior to contacting I had 2 vendors try to sell me solutions for problems I didn't have. The price I paid for the inspection literally saved me $$,$$$. My selection of Bitarchitects was because they heard my initial concern, were quick to provide service, & provided communication from initial inquiry to the day of service.

Oooh!

Eye roll. What a clown show. Well here's the update that I promised, unfortunately it's not in the direction I was hoping. I got an immediate response to my review below, with multiple requests to remove the review. I stated that I was open to updating or removing it, if things improved, and we ended up having a couple positive meetings. So much so that we elected to continue to work with them on the next phase of the project. So over the weekend (Sept 12-13), they sent us the contract for the next phase. We signed it and sent over the requested payment. I was hopeful! I was mentally drafting a positive update to this review! On Monday I received acknowledgement of receipt of the signed contract. Immediately following that, I got an email that said, and I quote "Before we can resume, please remove the Yelp review so we can start fresh and have a positive experience moving forward as we help you with your project." Guys, my jaw DROPPED. (My husband sent me a simultaneous "WHAT THE F***" text lol) Let me reiterate, we had signed the contract, sent the payment, and THEN received an email saying they wouldn't begin the work until a brand new condition had been met. We were completely floored. But okay, I thought, benefit of the doubt, the guy that sent that email has the position of junior assistant on the website, maybe he doesn't realize that what he's doing - withholding work that has been paid for unless we meet a new requirement that we never agreed to - constitutes a word that rhymes with shmextortion. So I responded that this requirement is unethical, inappropriate, and possibly a breach of contract. I gave him every opportunity to walk it back, and then reached out directly to the firm owner to verify that this was in fact the position that Bitarchitects was taking. The only response I got is that we can terminate the agreement, so that's what we did. To their credit, they processed the refund relatively quickly. So yeah, I don't know. I can only speak to my experience, of course. The other positive reviews indicate that other people have had better experiences with them. But this all does make me wonder if other reviews have been manipulated in a similar manner. So caveat emptor I guess. Because I fully expect they will respond and try to spin this in some way that makes me look like I'm the unreasonable one, I'm attaching screenshots of the actual email exchange (just the initial exchange, because the junior assistant started texting me after that email and it went on for a while, until I went back to email to contact the owner). Redacting names and email addresses as a professional courtesy.

I was able to make this decision and be okay with it because he provided so much education and context. I am so appreciative.

It seems like the inspector is more for the seller rather then the buyer who is hiring them for contingencies. I have done construction management and commissioning before so I dont know how in my case where a window latch on an exterior window thats UPSTAIRS is considered a low priority where there is a fall risk, wind/gust that goes through since it cannot fully latch and would need a potential replacement - which in hand did not help our case with settling on the deal to get this resolved. Literally handed us a paper and not even a follow up call to discuss the contingencies on the home. All I got told was that they only look visually and even when I looked you could see it is a bigger issue than what it was marked as. Waste of $475 that I could've done myself, oh and when I email the owner Hulbert, same half response of excusing the poor inspection that was done. I do not recommend this inspector company whatsoever. I forgot to mention - his wife when I told her the situation told me "This happens when you get a home" like what kind of response is that, don't know but this family business is beyond disappointing and a let down to put it nicely. This establishment lacks the actual foundation of what and who they're doing this for. Also the inspection was 30 minutes for a 3 bedroom and 3 bathroom house....
