Hi, my name is Andrey, and I own Instant Home Improvements. I've had my company for two years, but I have seven years of experience in construction. I've worked mostly in northeastern New Jersey. I'm based in Sussex County, but I can travel to the surrounding counties. I have experience remodeling bathrooms, kitchens, and flooring, but my distinguishing skill is my knowledge of drywall installation and spackle application. I do most of the work inside homes. I always strive to ensure the client is happy with the finished project. I enjoy seeing the before and after of a home renovation and knowing that I did everything possible to make it turn out well.\n

"PERFECT! PERFECT! AND MORE PERFECT!
We found this place called Trust Builders, LLC, on Angie's List (Of Course), and James (people call him Jim) had answered the phone. I called him up on the phone letting him know what the situation was, and how bad it was. Jim did a perfect job with everything that he did here. First of all, this is a very hard working man. I have never seen anyone take out LARGE portions of walls apart, so meticulously, so perfectly neat and with precision skill. The wall sections that were damaged were removed and discarded. Jim gets right down there in the wall, and takes out ALL of the dangerous BLACK MOLD by removing that harmful horror that we lived with for so many years. He was working so vigorously and managed to vacuum out everything that was such a difficult and tedious job.
Jim worked for many hours on his first day at the house, RE-building the beams that rotted out on the first wall that needed work. Everything to perfection. The next and last visit to work here, was just as industrious and he just works his heart out. This guy worked so hard, we felt that he was really true to his word. He gave us a written estimate of EXACTLY what work needed to be done, and to the mark, we paid that exact price. In fact, the verbal price we were quoted at the beginning was higher than what we actually paid, due to the fact that the second wall was not as rotted as the first, and required less work. Jim told us that himself, he didn't mince words or take extra because it didn't require as much work as the first wall. Very Honest, Jim let us know right away, there would be a REDUCTION in our estimate.
*************************************************************************************************************************************
I'll tell you something, this guy puts hard work, sweat and strength into his work. Jim KNOWS this business. He acts like a PROFESSIONAL throughout, he was prompt, and got started almost immediately. He even ran out to get the materials after he was here, showed us receipts for all he purchased, and even left us the extra materials! I would ABSOLUTELY hire Jim again on the spot. All I can say is, a job like this takes a lot of precision. If a contractor doesn't do the work correctly, harsh chemical black rot irritants could become airborne. He was very careful and we got kicked out of the room to the upstairs (nicely) for our safety. He cleaned every bit of the areas that were worked on, that the area didn't even seem like anyone worked there. Only that it looked so much better. Great Job. If you know anything about carpentry, if it isn't done right, it becomes a real big problem. The price that we received for all of this work was unbelievably reasonable. VERY REASONABLE FOR ALL OF THE WORK THAT WAS REQUIRED OF THIS JOB. Friendly, Professional, Business - Like, and knows the business. Is there ANY reason to use anyone else? I recommend Jim for this type of work. You wouldn't believe all of the other beautiful woodwork he does. I've seen it in pictures. Everything as promised here both in work detail and in price. WHAT ELSE CAN I SAY? AT THE END OF THE DAY, WE WERE EXTREMELY PLEASED. Hire again? ANYTIME! YOU BETTER BELIEVE IT : )
****************************************************************************************************************************
AND I HOPE THAT WE ARE ALLOWED TO SAY, WE LOVE EVERYTHING THAT HE DID FOR US AND LOVE HIS WORK!
*********************************************************************************************************************************
THIS IS THE WAY WORK AND SERVICE SHOULD BE! GOOD SERVICE IS RARE THESE DAYS. WE ARE HAPPY CUSTOMERS! "
