Frequently asked questions

How often should a sump pump be replaced in Delaware?

Most pumps last 7–10 years. Homes in low-lying parts of Delaware and Wilmington that run the pump often should plan on the shorter end.

Do I need a battery backup?

If your basement is finished or storms in Delaware knock out power, yes. A backup keeps pumping for hours during an outage.

Can you come out during a storm?

Yes. Sump pump failures are an emergency call for us, 24/7.

Restaurant grease line kept backing up. Now on a quarterly jetting plan with Straightline and we have not had a backup since.

Burst pipe in the crawl space. They stopped the water fast, replaced the section and insulated the whole run so it will not happen again.

Grace K.Elsmere, DE
★★★★★

Pre-purchase plumbing inspection found a cracked sewer lateral. Saved us thousands in negotiation. Worth every penny.
