What Clients Are Saying
Clients liked
- “From soundproofing the bedrooms (crazy quiet) to the window screens that you can’t even see are there on every window.”
Some noted
- “I’ve never experienced in 22 years of dealing with suppliers the low and ugly customer service like in Lang exteriors, everything started in the north branch (Pulaski Ave) where is only two ladies behind the counter, i had to deal with them quite few times and they have the worst attitude to their clients I ve ever seen, not only with me but with other GC, so, i made a big order about some re screening frames and new ones, since they were the only ones i would go for windows they gave me the total price and paid, my client (the owner of the building) saw my materials invoice so i can het back the money i paid and he got very upset, he even called me and asked me if i was taking advantage of him!”
