"your team was very impressive. We had other people out there inspecting the crawlspace, but no one except for The Crawlspace Crew had the guts to crawl the whole thing in the not so pretty parts of the crawlspace, and because of that we noticed that he had a broken pipe and leak. You were very impressive with your services, I wish you did plumbing too! I believe one of your guys is a home inspector (Travis I think?), and he was really thorough and good and he is on the maintenance board for the HOA and he wants to recommend to every one of their homeowners that we inspect their crawlspace."

"I highly recommend NW Sundance. Setting up the appointment was easy, they called 30 minutes before they showed up to let me know they were coming like promised, arrived on time, and quoted me the repair price all in a very effortless matter.The plumber Jorge was a great guy. Very professional, outgoing and efficient. He even cleaned up his mess when he was done, not leaving a trace behind that he was even there, except for new pipes and the garbage disposal he just installed for me. Even disposed of the old unit for me, without even asking. I am very impressed with these guys and will use them again if the need arises."

"I had Henco help with my new home water conditioner installation(pre-brought from Pentair). The job was done super well and the guys(Nolan and Zack) who came out were very professional and willing to explain all the little details about what I needed to know about the system and the plumbing work. I am glad I hired Henco, and I will definitely go back to them if any plumbing job is needed in the future."

"Equipment, which is hard to come by these days was set aside for my job once contract was signed. Schedule and arrival was a very smooth process with plenty of communication in between. Sales/estimator was professional as was the installer. Left both work area’s clean."

Sump Pump Installation FAQs, answered by experts

Yes, it’s normal (and beneficial) to have a small amount of water in the bottom of your sump pit. It shows that your system is collecting groundwater, rain, and excess water from around your property—just like it’s supposed to. However, if the sump pit is always full, you might have a leak or a faulty sump pump.

Start by calling a plumber if you want to install a sump pump battery backup. Talk to them about your situation and needs. Sometimes, electricians or waterproofing contractors will install a battery backup, and in that case, the plumber you call should be able to point you in the right direction.

Every three to four months, you should clean any dirt and debris off of your sump pump. You should also check the inlet screen (at the bottom of the pump) to make sure that it isn’t blocked. On top of that, you should deep clean your sump pump once per year—or hire a sump pump pro to do it for you.

There are a couple of similar alternatives you may consider for a sewage ejector pump, including a grinder pump or a submersible sump pump. Submersible sump pumps protect your home from flooding from outside water, though, rather than handling wastewater from inside. A grinder pump macerates, or shreds, solid waste before pumping it onward to the sewer line.

Sump pump repairs are typically handled by plumbers or waterproofing specialists who are experienced in handling basement and foundation-related issues. Plumbers can address issues like clogs, electrical problems, and mechanical failures, and waterproofing professionals may be ideal if the sump pump is part of a larger drainage or waterproofing system. 

Some people may also call on a general handyperson for minor sump pump repairs. However, for complex problems, hiring a certified plumber or waterproofing expert ensures the work is done correctly and prevents further issues.
