Our opinion, based on the 11 reviews we analyzed from Google, Yelp and BBB · Analysis updated Jun 2026 · How we decide ↗
What reviewers praise
Decade-long repeat customers citing precision workmanship — Vadim catches factory defects others miss, e.g. replaced anode rod on brand-new water heater immediately without leaving customer without hot water.
1 cited review
“We have been working with Vadim for well over a decade, and he is truly the person you call when you want the job done right. He is often the one fixing inferior plumbing work that others couldn't get right the first time. He's excellent with water heater installations, dishwashers, and any plumbing project that requires skill and attention to detail.”

Multi-trade capability (plumbing + structural + HVAC + flood restoration) means fewer contractors for complex repairs — confirmed across multiple projects over 5 years.
1 cited review
“They also handled a very complex repair involving a broken sewage line that was pinched between an HVAC duct and a structural support beam, which caused my basement to flood. Perfectum managed the situation professionally at every stage—performing water mitigation, thoroughly drying and disinfecting the area, and completing full flood restoration.”

“My partner and I hired and signed contract with Carlos General Contractor & State Plumbing LLC on 12/12/2017 for $34,000 to complete the work that the Montgomery County had already approved with the proper drawing from a licensed architect and to obtain my Use and Occupancy permit from the county.

The evidence — in reviewers' own words
Positive
“I first used Perfectum Construction and Plumbing in 2021 and had a great experience. Vadim replaced my water heater, pressure reducing valve, and the main water shut-off valve. He came on short notice (water heaters are always an emergency) and advised me to replace the pressure valve and the main shut-off. His work was very professional. It was clear that he insists on doing things the right way. When he replaced …”
“I’ve been using Perfectum for quite a few years and have always had a great experience. On one occasion, I couldn’t winterize my back hose bib. When Vadim, the owner, arrived, he quickly realized that the original internal shut-off valve installed by the builder also shut off cold water to my kitchen faucet. Vadim carefully analyzed the piping and was able to install a dedicated shut-off valve in a very tight …”
