"EXCELLENT! It was a somewhat emergency call because my walls were being damaged by the water, and Matt replied right away to my call trying to fit me in. He text back and said one of his guys, Ryan, was available and on his way! Ryan was great! Courteous, professional, punctual (and bonus - he unclogged the bathtub drain!). Thank you for saving the day!"

"We had a damp crawlspace. John's installed drainage with sump pumps (lead and backup with battery backup power) and encapsulated the dirt with 20 mil plastic. They also installed PU foam around the perimeter foundation walls to complete the insulation envelope of the house and a dehumidifier top keep the crawlspace area dry. In short, this work solved the problem we had and provided the added benefits of a more energy efficient and comfortable house due to the insulation as well as better indoor air quality. The work was done in four days and at considerably less cost than a competing contractor bid to do it. Another person that we had inspecting house later looked at the crawlspace and commented, "Wow! You could do brain surgery down here." We actually wouldn't recommend that though ;)"

Sump Pump Installation FAQs, answered by experts

Costs depend on pump type, labor rates, and the extent of repairs or installation needs.

Thankfully, you do have a few sump pump backup options in case it fails. One option is a battery-powered backup sump pump. Another option is using a portable backup generator as a power supply for your sump pump. Unlike a battery-powered backup which has limited power, a generator can run around the clock for as long as you need it. 

Or you can opt for a water-powered backup pump, which uses your home’s water supply as a source of power. However, this may not be the best option if you find your house frequently has low water pressure.

Yes, it’s possible to install a sewage ejector pump outside rather than in a basement. However, there may be some extra steps involved, including running pipes from the inside to the outside of your home and digging (and re-filling) a hole for the basin. If you aren’t comfortable with this type of work, contact a plumbing pro to handle it for you.

Repairs typically take 1-2 hours, while replacements, depending on accessibility, may require up to 4 hours.

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.
