"We used to love this service and gave them glowing reviews on Google in the past, but something has changed. Their customer service sucks, they don't apologize, don't call back etc. We had a hot water heater installed 2 years ago. It is still under warranty. Yesterday, 11/9/25, it broke and started leaking badly - still under a warranty from them. A.J. Perri advertises as they are 24/7 company, but they would not come yesterday and would promise us that first thing this morning, at 8 am, they would be knocking on the door. They never came, never called and never apologized. In fact, they have an attitude for misleading us and at 10 am mo one is here. The technician (do they only have 1 technician?) Is over 1 5 h away at another job. Customer service sucks with them really badly and now I feel as because we called them and voiced our dissatisfaction, no one will reach out to us or help us, while we are covered by their warranty. We had to pay for another service last night to pump"

For over a decade, the power washing and roof cleaning contractors at TruClean have worked hard to provide the most exceptional property cleaning services to residents and businesses. Our professionals are highly adept at wide range of amazing services including pressure washing, soft washing, roof cleaning, concrete cleaning, rust removal, and more.
"As a licensed Architect in NJ and NY, who has recently retired from a large-scale Construction Management firm in NYC, I am very familiar with various building trades and the properties of materials. I also pride myself in having a trained “eye” as well as the experience of interviewing and selecting the most appropriate trade contractors for our projects. Upon my initial contact, TruCLEAN sent out a “point person” to view the exterior of the house and photograph the various roof silhouettes and visible conditions. Based on these photos, augmented by GoogleEarth imaging, they were able to very quickly generate a competitive cost quote to clean our 11-year old cedar shingle roof on our circa-1930’s Tudor style home in Summit, NJ. Our house is located on a sloping site and is two-stories high at the street elevation and three-stories in the rear terrace. While our roof is not that large in total surface area, it does have a very steep pitch, along with cross-gables, two dormers windows and three shed roof appendages. The cedar shingles had lost their original soft honey color and had weathered to a dark gray/green color over the past decade, due to the shade from the surrounding tall oak trees, and constant moisture, which promoted the extensive growth of fungi, mold and mildew. Other roof cleaning contractors, surprisingly either did not visit the house prior to submitting a cost estimate or once they saw the house, were intimidated by the extent of the mold and mildew and declined to offer to perform the work, since they were not confident that they could accomplish what I wanted. As important, TruCLEAN was the only roof cleaning contractor to proactively provide me with a copy of their all-important current Certificate of Liability Insurance, something that many homeowner’s overlook at their own risk when hiring contractors to work in and/or on their house. As someone in the A/E/C industry, I certainly appreciated Gregg Giordano’s willingness to consider and ultimately accommodate my wishes in finalizing the Scope of Work for this residential roof cleaning project. I also was grateful for his taking the time to answer all of my questions, discuss the pros & cons of alternative cleaning ideas, methods and approaches, allowing us to settle on what actually made the most sense for our wood roof and its existing condition. His recommendations based on his team’s time-tested experience, have resulted in a beautiful cedar shingle roof that has now been thoroughly cleaned, restoring it to its original beauty, using the following procedures: Like most homeowner’s I was initially concerned that the various landscaping planting and shrubs around the house might be adversely affected by exposure to the cleaning solution. The TruCLEAN technicians provided and installed TYVEC tarps as protection covering over all of the shrubs located around the house’s foundation. They also constantly wetted with water prior to and during the application of the SoftWash solution on the house roof. They also “bagged” designated roof gutter downspouts that dislodge at grade, to catch the initial run-off of the SoftWash solution to prevent harmful soil absorption, and disposed of the filled bags afterwards. As agreed, the TruCLEAN team of three experienced technicians, applied their SoftWash cleaning process to all of the cedar wood roof shingles to kill the accumulated fungi, lichen, mold, mildew spores and moss. TruCLEAN’s SoftWash liquid solution consists of a customizable proportion of sodium hypochlorite (SH), as the active fungi removal chemical compound, diluted with water (H2O), along with SLO MO SOFTWASH FOR SH, a very thick, concentrated, non-hazardous surfactant that increases the dwell time, minimizing the initial runoff of the solution, allowing it to better permeate into the cedar shingles, enhancing its effectiveness. Using appropriate extension ladders of varying heights, with corkers and stand-off stabilizers, as necessary, the TruCLEAN team applied the SoftWash solution by gently power spraying it using minimal pressure to reach, cover and saturate all cedar roof shingles, letting it be absorbed into the wood shingles for as long as deemed necessary, repeating the process on certain tough areas, as needed. After a short time and noting the visible progress of the cleaning action, the TruCLEAN team then began to continuously spray with low-pressure water, all roof shingles, neutralizing the chemical action of the SoftWash solution and dislodging and rinsing away all of the dead algae. Even when wet, it is visibly discernable that the cedar roof shingles have returned back to their natural color. After the cleaning process has been completed and the cedar shingles have dried out, the TruCLEAN team returned to our house for the final step of applying either a citric acid or an oxalic acid-based wood brightener solution to all of the cedar roof shingles. This final step acts as a topical wood preservative, resulting in enhancing the natural honey color and grain appearance of the cedar shingles, helping them retain that appearance for a longer period as the wood weathers naturally. Ultimate, my wife and I are most pleased with the final result of this cleaning. Aesthetically, the finished work makes the cedar shingle roof an even more attractive focal point of the house, complimenting the overall style and architectural details of our home. We have received a number of compliments from friends and neighbors who have seen the cleaned roof and agree with our sentiments. If interested, I would be pleased to speak with any of your prospective clients to relay my positive working experience with Gregg and his most talented, experienced, polite, and energetic team members. I commend all of them for the professionalism, expertise, and efficiency. Particularly, their sensitivity to protection of our property, as well as their flexibility to diagnose and deal with unexpected conditions and additional client requests and leaving the property cleaner than they found it. It was obvious that Greg and his team take pride in the high quality of their work and are eager to accommodate, if not exceed, the expectations of a demanding client. Alexander V.

"It want poorly. The company sent someone to provide an estimate. He used a drone to take photos in the area of the leaky roof. He provided a verbal estimate. Then no followup. I call them, and was told that they had no record of ever coming to my home. I waited a bit, called them again, and they sent another person to provide an estimate. The estimate was close to the first one. And again, I hear nothing from them afterwards, in spite of 3 phone calls asking for a written estimate and for scheduling the job. Then I gave up and hired another company."

"Sean and his crew renovated my condo after a flood damage in early January. This is our first remodel project and prior to working with a contractor, we've heard pretty negative stories about GCs in general. And to our surprise, Sean was the exact opposite of what we've heard. Communication - I would rate myself as a very responsive person and because the remodel happened after a flood damage, I was quite in an urgent situation and was eager to get the project finished. Sean communicated with us in a very timely manner and on many occasions, live - as they perform a specific task within the unit. He responds to my texts throughout the night on matters and feedbacks I provided (re: inspection at end of day on a daily basis). Project timeline - we finished the entire project (lighting, kitchen, drywall repair, painting, floor installation, room re-arrangement, door/trim, baseboards, everything but tiles in the bathroom) within 5 weeks (which was my target). While there are glitches during the project, Sean was very honest and frank about the project and always communicated about the progress and delays if any. He arranged the day-to-day work appropriately so it uses the best of his crews' time and meet our deadline at the same time. Quality of Work - i can't complain about the integrity that goes to the work. Sean will be sure to modify and change anything that I expect, and if he doesn't, he would make sure he explains it so I can accept the reasons behind them. That's very important to me as a client. Even after the project ended, when we saw the need for minor fixes after we moved back in, Sean stopped by on several occasions to fix those things. Pricing - Sean's quote was very reasonable and he provided an extremely detailed breakdown of the costs (materials and labor). We know what we are getting, and it was this level of transparency that ultimately led us to hire him for the job. During the project, he provided receipts and if there are any incremental costs not foreseen before, he'd communicate that prior to purchasing. In the end, we spent maybe just a little over $1k more than the quote (which is VERY GOOD) compared to many stories I've heard. He even assisted in providing information to my insurance company for the claim, and was very happy to do it. Overall, I think he's professional and certainly added an extremely positive reputation to his industry. I would certainly work with him again in the future and have already recommended him to several neighbors."
