Feb 07, 2016 Report
I moved into a new house in May, and based on the inspection, the master bath toilet was leaking and stained the drywall taping. I had Peck and Weis do reseat and seal all the toilets, clean drains, and install a faucet. Job done no problem. Then I had drywall company re-tape seam and had ceiling painted. Peck and Weis also fixed a hose spigot and serviced air conditioner. No problem. However, six months later, master bath toilet leaked again and ruined drywall job.

I called them and there was zero customer service and maximum attitude. I was informed any work done was only under warranty for one month, which seems ridiculous. I think if anyone knew their policy they would never consent to hiring them. They fixed it, and so far so good, but charged me 284$ to fix it (were kind enough to give 100$ off) but in my opinion are responsible for ruining the drywall and paint job; 200$ was what just the drywall work cost.

I would have been content if they just fixed the toilet at no charge - everyone makes mistakes - as was evident when the other plumber they sent out looked at the toilet. But not owning up to it and poor customer service when something went wrong will prevent me from ever calling them again.

We set up an appointment to have our furnace checked out for the winter and central air winterized. We were questioning whether we would have room for a humidifier and they made a special trip out to check and see before the service man came out, to see if we could so that they would have the parts on hand at the service appointment. That is excellent customer service!
