Procon is a truly outstanding technical consulting company. My experience with their professionalism and methodical approach has been excellent.

For nearly a year, I had been struggling with a severe seepage issue in my flat. Despite multiple repair attempts by our complex maintenance team, the problem remained unresolved. Eventually, I came to know about Procon and decided to seek their professional consultancy.

Mr. Koushik Sarkar ,from Procon has been exceptional throughout the entire process. He personally visited my flat and conducted a very thorough investigation of the seepage area—not only inside my flat but also in the flat above—to accurately determine the root cause. What impressed me the most was his use of **advanced thermal imaging technology** to scientifically detect the exact source of the seepage.

He provided clear evidence with detailed images and prepared a **comprehensive rectification plan** outlining the necessary steps to resolve the issue. Our flat maintenance team followed his recommendations, and the seepage problem was finally fixed.

Another remarkable aspect of Procon’s service is his responsiveness and dedication. Even though I am currently in the USA, I was in constant touch with him during the repair work. He guided us at every stage, promptly answering questions and providing the correct instructions whenever required. At no point did I feel that distance was a barrier to communication.

I am also attaching some of the detection details they provided, which clearly demonstrate their professional and scientific approach.

I highly appreciate Procon’s expertise and would strongly recommend their consultancy services to anyone facing complex structural or seepage issues.

In my apartment, I noticed water dripping from the ceiling in my kitchen. So, I asked Procon Technical Services to check where the leak is so that we can fix it. The engineer from the company arrived on time and used equipment to scan the area. Based on the report, we did the necessary plumbing work, and the dripping stopped. I'd like to thank Procon Technical Services for providing professional service to resolve the issue.

My words are not sufficient to describe my feeling. Still will try my best.
One of the finest house renovation work in kolkata with their deep knowledge and guidance.
I must be thankful towards the owner of this company (Mr. Kaushik) for his guidance and the knowledge of “ what is required to fix my house construction problem and align workers to do exactly the same”.
Image will tell the end product difference but I was witnessed of whats done inside to fix the root cause of damping issue, water-logging problem, fresh drainage system installation and lot more.
All the necessary chemical treatment were done for iron rod as well as for plastering and injection process to stop ground damp.

I must mention the key workers name ( AJIJUL, Ashraf, Ikbal, Faruk, Rony) who showed dedication, diligence in the work and never said “NO” in any of my request.
It was long timeframe of 3 months plus and all the workers were like my house member since day 1 to last.

Loved it. It’s bit expensive but worth it. I must recommend to all who wants best service on house repairing and damp proofing.

Recently we hired Procon Technical Services for the interior painting work of our flat. They used top-quality materials (Asian Paints) and delivered a perfect, smooth finish. Professional, tidy, and great value. We are highly impressed by their service. Will definitely hire again.

Picking a trustworthy review for building repair services required looking beyond just star ratings.But we are glad to state that we have found
PROCON to be just that---
Trustworthy.
We were looking for Consistency, Professionalism and above all Timely service,since we had to get the work done in a specific period of time.
The roof repair work and waterproofing of our house terrace was done meticulously.
We are glad to state that we found all the qualities we were looking for and are quite satisfied with the results.Hence , without hesitation we would recommend "PROCON".

Procon is a really comendable service provider with regard to providing solutions related to water seepage & leakage, under the able guidance of a true professional, in the subject, Mr. Koushik Sarker.
Water seepage in builings is commonly faced issue and is extremely hard to detect & suggest due and proper solution to the issue. Water seepage causes huge damage over a period of time, if not addressed at the right time, it results in huge financial losses.
I was facing this problem in my residence, due to some unauthorised alterations done by a co-resident, occupying the flat above me, though the same was not agreed to by the said co-resident.
I got contact details of Procon from a friend of mine and contacted Mr. Koushik Sarker.
Mr. Sarker conducted the inspection in a very scientific manner, with the help of Thermal camera, Raddar Scanner, Endoscopic camera & Digital Moisture meter and proved in front of all concerned the cause and effect of the seepage. The report (an elaborate one, with all pictorial proof) submitted by him could not be refuted by the person at fault and the necessary repair work had to be done by him.
It would be pertinet to mention that Procon not only detected and proved the issue, they also provided due and proper suggestions and solutions, with regard to repairs to be done, for the closure of the issue permanently.
I wish Procon in general and Mr. Koushik Sarker in specfic All The Very Best !! May they keep up the good work in providing solutions to distressed people like us,in future.

Thanks to the best Restoration, waterproofing & heat insulation Engineer of Kolkata , Mr. Koushik Sarker of Procon Technical Services for giving us great relief from tremendous heat load from our roof and other waterproofing and structural problems of our four storied house at Jatin Das Road, Kolkata-29.
Their concept, design, implementation, monitoring of the XPS ( Xtruded polyesterin board) overdeck insulation on my roof is excellent. We are feeling practically much more comfort than the previous situation. It is 10-12 °c less heat.we were unable to stay top floor for heat in the month of April, May but now we are staying there without AC.
Mr. sarker and their team is highly professional, efficient, effective, and reasonable in pricing.
I have full trust in him.
