Reviews

What customers say

Several customers describe trouble getting assistance or completing a purchase. One prospective buyer says receiving multiple door terms and definitions contributed to abandoning a planned order; the same reviewer says they were told windows came as glass without frames and that shoppers looking for certain light bulbs are yelled at and chased out of the store. A customer who built small multifamily projects praised working with Mike Borger.

Bottom notch uncustomer service. We went around in so many circles just trying to buy new doors that it became impossible. I was given 5 different names and definitions for a door, none of which was discussed when i came in 3 months earlier. I was ready to buy 3 interior doors, i knew exactly what i want also ready to buy the jigs to drill my own holes. I was ready to order and hand over my credit card. Nope. Not anymore. Each definition and name comes with a different item commonly found on doors. None of the options come together in one piece to make a whole door, just certain pieces of the door. None of them come with door frames, those have to be made from scratch which is not what i was told earlier. I was also told windows also dont come with window frames either, you have to make those as well, you just purchase the glass. After going around in so many circles it got to the point where I had to throw up my hands, give up and walk out. Im still not sure if this was a joke as i was being laughed at as i walked out the door. Also someone will yell at you and chase you out of the store like a crazy person if you're looking for a light bulbs they don't like.

Went in 40 minutes before store closed. Spent 20 minutes walking around their kitchen and bathroom center. After not finding an employee either at the design desk or anywhere in the department. I heard the announcement the store would be closing in 15 minutes, so l went up to the check out registers and asked if anyone worked in the kitchen center. I was told "yes she is back there". Didn't you see her, that was my clue they had made enough money and did not want or need mine. So I walked out the door and went elsewhere. No service, no sale.

Bought cabinets from them two years later I got sick of waiting for the warranty faces to come in cause of swelling of the wood. Having to install myself and now half of the faces of my cabinets are white and the other half a faded white. I am having to custom fit each one because I guess in that time frame they raised the face of the drawers a quarter inch and they are now hitting the counter top. Rose was a nice lady but my experience was just awful. Do not I repeat do not go here

TWK INC.

Another failure no help around when you walk in the store don't bother buying anything unless you're a 150% you'll use it or it will work. We purchased couple supply lines threw out the packaging kept the invoice credit card receipt ect .. They will not return anything!! O and all their prices are 5 to $10 more per item then the local companies.. Go to Home Depot excellent return policy or Ace??
