Great experience with this company. Alan was really helpful from start to finish and was quick to respond to our queries. Already recommended them to other construction sites. Thanks, Alan!
I can’t recommend ModCon highly enough. We had two new toilet and shower blocks delivered on Monday and have already ordered our smoking shelters with them because they’re so good. Everything arrived as promised and ready for use.
We got our new office units through ModCon and couldn’t be happier with the results. They look great and the guys from ModCon went out of their way to make sure we had everything we needed. They’re really friendly and easy to talk to as well.
