"Harts corrected the location of the crawlspace sump pump discharge line to the location in the foundation which I originally wanted it to be located. However, we did not hear the sump pump operate under the floor when first installed. When the Harts crew changed the location of the pump discharge line, we can now hear the pump very distinctly when it operates, under the floor. I am requesting that Harts come back and listen to see if it is normal for the sump pump to make this much noise."

"G&S did an excellent job installing our new furnace and AC unit. The best thing about G&S is that they warranty for 1 year. The circuit board in our furnace failed within a couple of months (no fault of G&S). Manufacturers warranty would cover the parts cost but G&S repaired and covered labor cost under their warranty. Also they diagnosed the issue and repaired very quickly. Definitely A++ installation and service."

"Bottom line - I am happy with our three-head ductless Mitsubishi heat pump installation. It now functions properly and looks good inside and out. Controllers work well. Units are super quiet. Price was mid-range so reasonable. But…it was not a smooth road to get to this outcome. Started off well with a quick response to do a site visit and prepare an estimate. The tech was knowledgeable and provided accurate information (I had consulted with a home energy consultant and did online research). It took some work on my part to get a correct final bid that included the proper rebates – I had to correct their first one because it was for two heads rather than three and then get the rebate deducted. Scheduling the installation was easy and prompt and was done in 1.5 days. The two person team had good judgement about where to put the external conduits and locate the heat pump. BUT – they installed the refrigerant lines incorrectly (crossed the connections to the pump) so the heads iced up and then leaked water. They came back a few days later to fix the problem and now the heads work fine. But they did not properly reinstall the sheathing around the lines, which City inspector noted. So they had to come out again to fix this. They have a great zero percent financing deal with Synchrony bank but could not answer questions about how it worked, the terms, etc. Took a fair bit of time to sort this out with the bank, but seems to be set up now. I asked three times to get copy of warranty and registration of equipment with Mitsubishi for my records but never did receive this."

"Don't hire anyone else. If you're looking for a company run by someone who understands what customer service looks like, call Perma-Dry. 4 years ago we worked with Perma-Dry to install an internal basement footing drain system - they were prompt, responsive, and did a great job. We've had zero issues. We recently discovered an issue with an old external drainage system (not installed by Perma-Dry) which backed up during a thunderstorm. When I discovered the issue, I called Ryan (owner) to get some help; he showed up at 9am on a Saturday (his day off) and spent 5 hours with me troubleshooting the issue and coming up with a temporary fix until he could get a crew out to install a permanent fix. He not only was a huge help, but his attitude was incredible - he was actually having fun working on his day off. In the 12 years I've owned my house, I've worked with dozens of contractors and never had an experience like that. True customer service is a lost art, Ryan and his team have shown us twice that they understand how to take care of customers and care enough to do the right thing."

"Hagee Plumbing technician Caleb arrived on time, super friendly, and went straight to work. He was able to repair my garbage disposal and save me a couple hundred dollars in the process. I highly recommend Caleb and will definitely ask for him directly if I ever need any plumbing work done."

Sump Pump Installation FAQs, answered by experts

The most common cause of a clogged sump pump is natural debris buildup. As water enters the sump pit, it can carry small pieces of debris that build up over time, or the debris can get caught in the filter. If you forget to cover the pit after cleaning the sump pump and pit, debris can also collect in the pit. Corrosion on the metal discharge pipe can also clog the pump. Additionally, if your pipes freeze, it can prevent water from draining properly and cause a clog.

Grinder pumps alone cost $300 on average. The average cost to install a new grinder pump is between $2,000 and $4,000, including the pump and labor. This price can also change based on the exact type of grinder pump you choose, labor costs in your area, and the power system your home currently has.

A water pressure booster doesn't require special maintenance. Like any house system, inspections should be a regular part of your annual schedule. Check for leaks, faulty valves, pressure loss, and mineral build-up. Pressure loss could be a result of mineral build-up, and you can descale the system with a vinegar and water solution.

Sump pumps prevent basement flooding, reduce humidity, and protect against water damage.

Some sump pumps are powered by water rather than electricity. Water-powered sump pumps generally use one gallon of city water to pump out two gallons of water from its basin. Therefore, if you're looking at a potential 10,000-gallon flood, your sump pump will need to use 5,000 gallons of city water to prevent it.
