Basement flooding and sewer backup in Philadelphia

Plumbers for backwater valves, sump pumps and drains.

99 pros in Philadelphia

In Philadelphia, basement flooding prevention has a local programme attached to it. The Basement Backup Protection Program gives eligible homeowners free backwater valve installation and, if needed, free downspout modifications, for people whose basement fixtures back up with water in wet weather. That changes what you ask a contractor. If you qualify, the work is done by licensed contractors under a one-year warranty, and you are responsible for repairs and maintenance once that warranty ends. Eligibility also depends on your water bill being current, or on a payment agreement, and on addressing any violations from the Philadelphia Water Department or other City agencies first. So before you hire privately, check whether the programme already covers your valve. Ask any trade you consider whether they are licensed, what warranty they give in writing, and who handles maintenance afterwards. Keep in mind that the Pennsylvania Insurance Department says standard homeowner's and renter's policies do not cover flood damage, so prevention work matters.

  3. Put it in a written contract: the work, price, deposit, start and finish dates, warranty, permits and clean-up. Paying cash to skip it leaves you no recourse.

Questions about hiring in Philadelphia

Can I get a backwater valve installed in Philadelphia without paying for it?

Possibly. The Basement Backup Protection Program offers eligible homeowners free backwater valve installation and, if needed, free downspout modifications. It is aimed at people whose basement fixtures back up with water during wet weather. Check your eligibility with the programme before you book a private contractor for the same work. City of Philadelphia (source, opens in a new tab)

What do I need to do to qualify for the Basement Backup Protection Program?

Your water bill must be current. If you are behind, you can still qualify by paying in full or entering a payment agreement. You must also address any violations issued by the Philadelphia Water Department or other City agencies before your application can move forward. City of Philadelphia (source, opens in a new tab)

What should a written quote for sump pump or drain work include?

It should name the licensed contractor, describe the work and equipment, state the timeline, list any permits needed, and set out the warranty terms in writing. Ask who handles repairs and maintenance afterwards. Get more than one quote and compare like with like.

Will my homeowner's insurance cover a flooded basement?

Not necessarily. The Pennsylvania Insurance Department says standard homeowner's or renter's policies do not cover damage resulting from a flood. It also says flood damage can happen even if your home is not in a floodplain. Ask your insurer what your own policy covers. Pennsylvania Insurance Department (source, opens in a new tab)
