5.0 Vivyan C. Woodside, NY

My parents has a really old water heater that needed replacing and J and J came to their rescue right away with exceptional customer service, pricing, and quality of work. J&J contacted me within 15 mins after I sent out a request on Angi. I had only sent one quote request because it was my first time ever using Angi and didnâ t know what to expect. So glad I went with my instinct and chose J&J out of the list of many. Within just a few hours, J&J arrived at the house with the water heater and did their magic! Karol even installed a safety pipe that my parents did not have for 23 years and explained thoroughly why it is needed and gave more safety advice which my dad really appreciates. My dad is a very difficult man to please but he is very happy with J&J! My parents are elderly and have an old house that by now, most things are breaking so I have been helping and working with many companies to fix so many things for the house this past year, including a new roof replacement just 2 weeks ago. Compared to other companies, J&J is honest, ready and eager to work, and their quality of work is professional which is very hard to find these days. How I wish I had found J&J sooner but I will definitely call them back for all future projects as well as recommending these two wonderful and friendly men, Karol and Martin, to everyone I know that needs any home improvement work done.

They responded quickly to my request and then made an on-site assessment which showed that the repair needed was more than I realized. I appreciate their honesty, courtesy, attention to detail and overall professionalism.

They came the same day and within hours Karol and Martin handled our leaky faucet and replace the pipe and drain need. I will definitely hire them again.

Karol and Martin were very kind. They helped diagnose an issue that had nothing to do with the problem theyâ d been hired to resolve.

5.0 Stan D. Valley Stream, NY

After speaking on the phone, they were here in less than an hour. They cleared the drain blockage, and all is well. Good service in a professional manner

Response from Company:

Thank you for your opinion.

5.0 Grace J. Brooklyn, NY

Very quick to respond through phone and text. They were early and on time which is already a good sign. Unfortunately we couldnâ t get the full job done the first time but Karol was very knowledgeable and helpful. He was understanding about explaining to us the process of what needed to happen and went to the store to get additional supplies. Will be going back to them for the additional work needed!

Response from Company:

Thank you.

5.0 Cj E. New Hyde Park, NY

We had lost our heat almost 2 weeks ago on a Friday (2 days before the first drop to below freezing temperatures). I requested 4 quotes via Homeadvisors.com that evening. The following morning, a representative from India called us back for Sears. They were not able to send someone out to us until Monday (we would've suffered through the deep freeze on Sunday). We never heard from the other 2 companies (don't want to name names). My husband heard from Karol of J&J that same morning. The great thing about Karol was that he walked my husband through different scenarios of what could be wrong with the boiler and tried to help him fix it over the phone. He was old school (giving great respect to the term) because he genuinely took pride in his craft, cared about fixing the problem, helped us understand the situation and was very honest. Since my husband couldn't fix it on his own, Karol came by the same day--took things apart with our 20-30+ years old but solid boiler, replaced a couple of parts and did a thorough cleaning. All is well since then. Other companies, for sure, would have told us a million other things were wrong and needed replacing. Other companies would have made a killing with us. We were so blessed and fortunate that we met Karol that day. I don't think that we will call anyone else in the future for any work on the house.

Response from Company:

Thank you so much to sharing your opinion.

Seal of Approval

What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.
  3. Verification of State Business Filings
    For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
  4. Criminal Records Search
    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
  7. Legal Search for Civil Judgments
    We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them.
  8. Liens Search
    We use 3rd party data sources to check the principal/owner of the business for liens placed against them.
  9. Identity Verification (SSN)
    HomeAdvisor verifies the social security number(s) of the owner/principal for identity check purposes. This check applies primarily to smaller business entities.
