Recommended Customer Reviews

Fast, professional service. Fair pricing and great customer service. Would definitely recommend giving Grand Slam a call for all your plumbing needs!

Grand Slam Plumbing came to us the same day and fixed our clog quickly and professionally. They were taking extra measures to be safe during this pandemic, and were helpful in answering our questions about the plumbing and water flow. We will definitely be using them again if we need their services in the future. Thank you!

We called Grand Slam on a Monday for a leak under our master bedroom sink per recommendation from a friend that has used them and liked them a lot. They were able to come on Tuesday and took care of the leak quickly. A great part of the service is they check all toilets and the water heater to give an update on the life span of each. Turns out we have a toilet that needs to be replaced due to the porcelain cracking and leaking. Will definitely recommend to our friends and family!

Grand Slam did an excellent job replacing our sink and piping and in a very timely manner. We will use them again when the need arises!

We had a bit of an emergency, and with all of the positive reviews that I read online, I reached out to Grand Slam. This is family owned and operated business. I spoke with Brittany, who was so sweet and knowledgeable over the phone and knew just what was happening with our sink (air conditioner vent backed up into our sink and was making it overflow.. who knew) she had Josh out to us asap, yep, same day and within a couple of hours. Lots of information and how to's for us to keep this from happening in the future. He cleared it all out, and no mess left behind. Honest, clean cut, informative and even wore booties on his shoes because it was raining outside. 10 stars if I could.

A+....unclogged main sewer line. Completed at a minimum charge. First plumber that came out reported the line was broke and repairs would be 5k

Had a great experience with Grand Slam from start to finish. Josh was able to come very quickly to fix a clogged AC drain. He was very friendly and hard working. The prices were more than fair and I would definitely recommend to anyone looking for a trustworthy knowledgeable p

I highly recommend Grand Slam Plumbing. I've used them for years and have always been beyond pleased with their services. Josh and his crew are very professional, thorough and clean..and always call you back and show up on time. They go above and beyond making you happy and explaining what they're doing and why. I won't use anyone else!

Friendly, helpful, and reasonably priced! We're so grateful that they were able to help us out with our weekend water line emergency. I would definitely use them again and recommend them to my friends and family.

Very pleased. Called that morning and they were out that same day. Fast, courteous, and professional
