After purchasing a dishwasher and discovering I didn't have the tactical aptitude to install it myself, I sought out a plumber to assist. After reading reviews and collecting quotes from dozens of local plumbers, I decided on F1. The cost was competitive and the only negative reviews I could find seemed to be from whiners that simply didn't like having to pay for a service. And, after meeting Daniel, I can confirm that this is the case. He came when he said he would and did the job quickly and efficiently. He even managed to improvise upon discovering that we'd inadvertently purchased a wire dishwasher rather than one with a plug.
If I ever have any plumbing needs again, I'll be calling/emailing Daniel.
