Protek
Company Overview
At Protek Co., we specialize in plumbing for natural gas, along with general construction and remodeling services. We concentrate on natural gas plumbing and everything associated with gas-powered appliances. We provide support for fireplace gas and electric conversions, patio heaters, seismic shut-off valves, BBQs, fire pits, underground gas, and other related needs. Our construction offerings encompass outdoor spa concrete and electrical preparations, kitchen and bathroom renovations, additions, ADUs, and new constructions.
Since our inception in 2016, Protek Co. has aimed to elevate customer experiences in an industry that often falls short in service and detail. With over 15 years of experience in construction, we offer a personalized approach to every project, regardless of size. Having worked as a residential and commercial plumbing subcontractor with various Bay Area builders, and remodeling high-end residential properties in the East Bay, we have a distinct perspective on project management. From simple plumbing jobs to extensive new constructions, we approach each project as builders, subcontractors, and owners, allowing us to guide our clients toward the most efficient completion. Our top priorities are delivering an excellent customer experience and maintaining high-quality work.

Recommended Customer Reviews

Damen plumbed a new gas line and installed an electrical outlet for our fireplace insert. He did an estimate free of charge and was very detailed in his scope of work bid. His communication was prompt, scheduling was straightforward and once he was on site, he executed the job flawlessly without missing a beat. Probably the best contractor we've ever worked with.

I highly recommend Damen of Protek Plumbing! He was recommended to me by East Bay Fireplace to do the electrical work needed before the installation of an electric fireplace. I am very impressed with the work he completed. Damen was so careful in covering my floors and furniture before beginning his work and he did a very thorough job cleaning before he left. Plus, it was a pleasure talking to him and having in my home. He is one of the nicest contractors I have had work in my home. Plus, his fee was very reasonable for the work he did.

Damen did my fireplace conversion last year and his work was top-notch. Plus, he's a really nice, fair-minded young man. I highly recommend!!
Big five stars for Protek Plumbing!

We recently wanted to update our wood burning fireplace to gas and called Protek to do the gas and electric work. Damen came out, explained our options, gave us a quote, and then scheduled a date to get the work done. He was actually able to come out a few days early to get most of the work done and then finished up on the originally scheduled date. We're very happy with the work, and highly recommend Protek/Damen!

This review is overdue. I worked with Walnut Creek Fire in October to have a new gas fireplace framed and installed. They recommended I have Protek Plumbing do the gas and electric work. Damen was incredibly professional and worked within the necessary timeframe (after framing, before the insert was installed). His rate was totally reasonable and was great to work with!

We are living in our 4th home and over 30 years have worked with lots of contractors. The vast majority accomplished the task requested but Damen is among the finest we have seen at focusing on ALL the details.
After one of his work days, before he was completely finished, I expected to see a pile of wood and concrete dust. His work area was nearly spotless. One of my biggest complaints with contractors is the mess they leave and expect me to clean up. While this might seem like a minor concern, I think it is indicative of the contractor's work ethic.
Everything about his work was also fantastic. The distance between the conduit, the near invisibility of the electrical connections, and the symmetry of the caulking make it clear to me that Damen cares about the details.
He and his contractors were timely: 7:30am meant 7:30am. He was also very creative in designing the work to minimize awkward turns and structures.
Finally, Damen put up with my constant questions. He is super patient and I would not hesitate for a moment to use him again.

I wanted to highly recommend Damen Nikolakakis of Protek Plumbing for installing a new water heater in our home. His work was top notch and was so professional, plus being a great communicator!

Best professional licensed plumber I have ever used! Damen is very trustworthy, knowledgeable, experienced, courteous, efficient, on time, insured and very fair cost for his perfect work. I highly recommend him for your plumbing needs other than backed up drains which isn't a service he provides.
Damen installed the gas and electrical for our new gas fireplace and he did an amazing job!! I will be hiring him again soon for some additional plumbing needs soon.

Damen is absolutely the best! We called him regarding an old fireplace gas pipe that was getting in the way of our remodel, and he was able to get out there to the home to look at the situation, called us and presented to us our options clearly. Everything was on time, as expected.
Damen is also very straightforward and honest. Once we gave him the go-ahead, he kindly squeezed us in his busy schedule when we told him how this was holding up the rest of the remodel.
The total came out a little less than what he quoted us. We couldn't be happier.

We undertook a major landscaping project, and our general contractor retained Damen as a subcontractor to put in the gas infrastructure for our outdoor fire pit. We were very impressed with Damen (he had had a working relationship with our GC for over a decade) and opted to hire him to install gas for our indoor fireplace. Damen was incredibly efficient, and expert at his craft. He was thorough, accurate, and prompt in his quotes, work, and billing. Damen was an absolute pleasure to work with; he also provided helpful advice and recommendations. We will definitely be using Damen for any of our future plumbing/gas needs!
