Recommended Customer Reviews

Excellent response time. I needed an inspection right away, for several areas of my property. Loren's team corrected the identified issues. I am grateful for the professionalism, the recommendations, response time, and quality of the work performed by PPC.

Thanks Lawren for rescuing our post-demo exposed wires situation. These wires were blocking the refinishing of the wood floor, so time was an issue. Lawren came by the next day after responding to our project on Yelp.
Lawren worked well within our parameters, for example he carefully cut through the subfloor to make room for the electrical box without cutting through our underfloor heating pipes.
Post the flooring work there were some sparks seen in the electrical box, possibly due to the moving around of the outlet by the flooring crew. Lawren came by to check on the work, and took the outlet to pieces, inspected each piece and carefully replaced them. He also ensured the cover fit snug on the new floor. The final product has a clean, professional finish.

Lawren was quick to respond to my issue. His estimate was also the best price. When he got here and checked the issue, it was a simple fix. He thoroughly checked to make sure everything was resolved. I also had a question about my doorbell and he sent me a solution, which was super helpful.

Pierson Precision Construction Lawren, was excellent in determining the cause of my power outage in the laundry room, he installed 3 new outlets and a light switch, Lawren does terrific work and would highly recommend him

In short: Top notch electrical work from Lawren, and on an emergency basis, highly recommended!
So after a very long day and in the wee hours of the early morning, as I was about to finally crawl into bed, I discovered that one of the electrical circuits in my apartment was no longer active. I checked the circuit breaker (fairly modern, maybe 20 years old) and indeed the circuit had tripped. But I was horrified to find that I could not get it to reset, and I tried many times.
Why this was so distressing was, not only was I exhausted as it was around 2:30am, but this particular circuit serves a room where I have a 10 cubic foot freezer stuffed top to bottom with recently stocked up frozen food. Even more distressingly, apparently the power had been off long enough unnoticed that day that the freezer was already warming up dramatically, well into the lower 20 degrees and climbing. Yikes!
In my pre-dawn grogginess, I hauled as much frozen food from this bulk storage freezer down to the regular freezer section of the refrigerator in my kitchen, packing it tighter than a Tetris puzzle. But that was only maybe a third of my stocked up frozen goods. So at around 4 in the morning, just before finally crashing hard asleep, I got online to Yelp requesting emergency electrical service. When I did awaken about three hours later, I found that Lawren of Pierson Precision Construction was one of the first to reply, and his was a standout response.
Lawren was able to fit me into his schedule within hours. Quickly upon arrival, he did his Sherlock Holmes sleuthing act to determine that the source of the problem was more than just a possibly failing breaker switch but was actually a corrupted electrical outlet OUTSIDE of my apartment, the outlet that serves the back patio. And did I say ""corrupted""? I mean MELTING DOWN. Literally smoldering hot and smoking from where yesterday's heavy rains and higher winds had apparently managed to push water past the outlet's so-called water seals (also maybe 20 years old), shorting it out quite dangerously. Once he could extract the destroyed outlet, it was shocking how charred and melted it was. I mean, how it didn't actually catch my building on fire I will never know and am eternally grateful that it did not.
Anyway, he replaced the entire outlet with a new and far better weather sealed GFC outlet designed for active outdoor use, along with replacing that circuit's breaker switch just in case its performance had been collaterally damaged during the short circuiting process. A couple hours later and I was safely back in business...even if I did lose a whole bunch of frozen pizzas. (Hey. Don't knock the dietary choices of a single guy who can't cook.)
To sum up, Lawren is exactly the kind of guy I want doing any of my future electrical work. I now have ""my electrical guy"", and will work with him for at least two planned projects, and can strongly recommend his service to others.

The owner (Lawrence) was excellent in determining the cause of our power outage in the kitchen and swiftly run to the store to buy an older type breaker and had the power back on in no time! I highly recommend Pierson Precision Construction! Lawrence's can do attitude and calm approach to the problem was assuring that I hired the right company! Best in class!

Lawren was great! He fixed our front gate buzzer and installed a Ring doorbell. He also went out of his way to pick up a part for the gate after I'd ordered the wrong part initially. Really nice guy, highly recommend PPC!

Lawren is a great contractor, very professional and thorough. He redid our bathroom with new toilet, bidet, flooring, shower door and fixtures. He installed new lights and thermostats. He kept us updated with the progress and got things done on time, just as he promised on the quote. He even picked up items for us at Home Depot when we weren't able to and made recommendations so we could make the right decisions. The quality of his work was outstanding and he even took time to clean up the place for us after he was done. I would certainly hire him again for future reno.

Lawren was great to deal with and did terrific work. We upgraded a breaker panel, installed pot lights, added a 240v outlet outside, and put in 4 new outlets inside.
Our house is old and the walls are tough. Lawren and his crew showed up early and worked hard and late to get it done every day. They did high quality work and didn't shortcut in ways that would lower quality.
We'd hire them again for sure.

I have worked with many contractors on a variety of projects. Lawren and PPC are one of the BEST outfits I've encountered. He is responsive, communicative, and honest. PPC delivered top notch work at an excellent value. I would (and have) recommend him to anyone in need of a contractor.
