JAY LITMAN CONSTRUCTION REMODELING & HANDYMAN SERV
JAY LITMAN CONSTRUCTION REMODELING & HANDYMAN SERV
For over 40 years Litman Construction Inc. has specialized in residential and light commercial remodeling, repairs and maintenance. Litman Construction has a full time crew who provide professional, skilled services to take care of just about any home, apartment building or business; repair, maintenance or remodeling project. With just a call, you can arrange for a convenient estimate or scheduling of your next project. You'll find our company a dependable, affordable and an efficient way to take care of all your home needs. Your satisfaction will be personally guaranteed.
"Litman Construction won a bid through St. Louis County to install a vertical lift (elevator) to make our home handicapped accessible for our son with special needs. We began the project in ample time to complete it by the end of our funding year. We completed our portions of the project and Sam assured us that the project would be done on time. Two weeks before our funding year ended, Litman construction began their work, assuring us it would get done. The lift had not been ordered, so our project was not completed on time. It lost our son $12,000 of county funding to use this year for a handicapped accessible shower and ceiling lifts to keep him and our caregivers safe during transfers. Litman apologized, but did nothing to make the situation right. They proceeded to blame us for the delays. My husband was up until 2 AM one morning removing a wall so Litman could begin their work. Had we known that Litman's delays would be that impactful, we would have done what needed to be done ourselves. We could have easily done what needed to be done in a weekend. Litman Construction essentially sheet rocked and painted a U-shaped "closet" that was 5 feet deep, 6 feet wide and 12 feet high. They added a 42 inch high wall on top of the 8 foot wall my husband had already built. They sheet rocked and painted 204 square feet and charged $5,145 for their labor (85.75 hours over 30 days). On-line estimates put sheet rocking at $1.50-$3.00 per square foot (materials and labor combined) which would put our project at $306-$612. Even though Litman did not touch the lift (Arrow-Lift the lift manufacturer installed it) they charged a 10% mark up on the lift, and the electrician they hired (TK Electric) wired the main circuit board incorrectly so it was destroyed the first time it was hooked up. Their response to that was "He's done them for us before, but I guess mistakes can happen." Litman construction did not even do their work well. They left sheet rocked seams for us to have to blend into a wall above (they painted up to bare sheet rock). The bottom door header was put in crooked (it is 36" wide) and the dimensions for the door were incorrect despite them having a plan. When the lift was installed, shims needed to be placed at the top so the door opened correctly. We had to fix all their shoddy work after we fired them from the project. There was no service recovery or effort to make their mistake right. When we knew that the project was not going to get completed before the waiver year was up, Sam, the project manager, told us that he has had funding extended (our social worker never had heard of that) and that my husband was handy so he could complete parts of the next projects to fit into the money we have left over this year. He blamed us for the delays. In the end, Litman was paid for their job and there was no accountability for them. I left a one star review and told our story on their Facebook page and they deleted all four of their reviews. They turned off the ability for people to post to their page except in the comments of their posts. Instead of responding to a complaint, they deleted it. That, to me, says volumes about their company. If you want timely, high quality work done, go elsewhere."

"Horrible The experience was awful with this people. I didn't know this company at all, my insurance company send me a list of 5 general contractors to take care of my house, so I pick J Benson because they were close to my house and I want it to keep the contractor local and close. So I went with them. They send an estimator like one day after the damage of the house, I signed the paperwork and two days later they send a different person because the first guy had previews commitments, so that was the first red flag. The second estimator took a lot more pics of the house and did he's first estimate, he submitted to the adjuster and it passed just fine. But then it took them almost one whole month before any one started to work in my house, not a single nail was removed or anything. Then I found out that numerous contractors were going in and out of my house with out me knowing it. Finally the work started and the job "foreman" got involved, this guy was even worst, he only called and picked up the phone when he need it something for me other ways good luck trying to get a hold of him. This guy should be FIRED and never allowed to work on the field again. One day I called him and he's answer was "what do you need, I am kind of busy right now" Awesome. Then I asked for an estimate to build a brand new bathroom in the basement. The estimator give me he's quote and we agreed on the price, so they started the project about one month after the paperwork was signed. About 80% of the work was done when I found out that the estimator "FORGOT" to add the toilet and the tub on the estimate!!!!!! How can any one do that????? So I had to came up with that $$$ And then there was the communication with office personnel. Since day one right after I signed the paperwork I offer to give them money, the estimator said "some one from the office will contact you" NO one ever did, weeks went by with out a single person contacting me about money. Finally some one did and every time we communicated there was a mistake with the numbers, every time there was an "I am sorry I forgot" Unreal this people. A couple of weeks before the project was done and I was super upset with every one involved at this point I requested a supervisor. He reached out to me and we meet at my house. He right away start asking me for money, I pretty much lost my cool there and I went off about all of the issues I was having with he's people. He's answer " I am sorry I wasn't aware of the issues" This shows how unprofessional this company is I can't believe how this people are in business not only in the twin cities but in southern Minnesota."

Professional Exteriors, Inc
Professional Exteriors Inc is a full service company with services ranging from siding and roofing to decks as well as snow and ice dam removal in the winter. With a wide range of capabilities PEI is able to meet all your renovations needs.
"very poor work quality, I had to have them come back 3 times after the initial installation to repair damages and fix the shoddy workmanship to get the roof right and it still hasn't passed Inspection. On top of that on three other occasions they were scheduled to be there and they just didnt show up at all. They left trash in my yard and in my driveway causing a flat tire on my car due to nails left all over the driveway. I even found missing shingles on a newly installed roof, how does that happen? I also found out after the fact they were TWICE as expensive as their competitors. I called 3 different contractors after getting their final bill and found this out. Twice the price for shoddy work? I'm just glad I was able to get up on the roof and check the quality of the work and demand they corrected it. My recommendation, hire someone else. There are so many other capable company's out there. You dont need to waste your time with this one. It's not worth it."
