Dealing with damp downstairs is stressful, but Basement Gurus is especially well-suited to homeowners who want a long-term fix rather than another patch job.
This family-owned team brings more than 30 years of experience and focuses on drainage systems, crawl space encapsulation, mold prevention, and structural repairs.
I like that they look for the root cause of the moisture problem before recommending work. This approach matters a lot when water is coming through more than one weak spot.
They also handle larger repairs, including Bilco stairs, which can be helpful if a project generates enough debris to warrant the best dumpster rentals in Philadelphia.
However, their approach can feel like overkill if you only need a small wall crack sealed, so I would call them for serious or recurring water problems first.
Great job
Basement Gurus and Josh did a great job with our basement water proofing project. They clearly explained what needed to be done, were fair on pricing and completed the work in a timely manner. The unfinished side of our basement never looked so good, and anything they moved for the job was put back like it never left.

I have mine done July 2025. Lucas check it out what’s the problem Im facing. I do have some ideas what waterproofing needed in my basement. I have couple of quotes done and I did the right decision by choosing basement gurus. Lucas gives me all the details and information needed on my waterproofing. He explained it well. The workers are excellent and very knowledgeable. I definitely endorse basement gurus. Make sure you check them out. Great job!!!

Heavy rain can expose weak spots fast, so Total Basement Waterproofing & Foundation Repair Philadelphia stands out for people worried about both leaks and structural movement.
Their work goes beyond basic sealing, with services tied to slab lifting, underpinning, wall fissure repair, and foundation stabilization. They also use modern repair products meant to stop small cracks from turning into larger structural headaches.
What I like here is the way the company talks about matching repairs to local soil conditions. Philadelphia properties can age unevenly, so a one-size-fits-all fix rarely feels reassuring.
On the downside, they’re closed on weekends, so consultations and project planning need to fit into regular weekday hours.
My basement is now completely dry
Total Basement Waterproofing did a fantastic job! Their team was professional, efficient, and my basement is now completely dry. Website is user friendly. I highly recommend them for any waterproofing or foundation repair needs in Philadelphia!

3. Over the Top Waterproofing

Address: 2999 Welsh Rd, Office B
Contact: (609) 846-8442
Hours: Available 24/7
Older Philadelphia homes require careful waterproofing because moisture problems can coexist with masonry damage, aging brick, and air quality issues. That’s where Over the Top Waterproofing feels especially useful.
With more than 25 years in the field, this family-run company combines water protection with restoration work. With this, it makes sense to consider them alongside top masonry contractors in Philadelphia.
Notably, their mechanics are trained in traditional craft restoration, so the team is a strong fit for older or historic properties where a quick patch could miss the bigger issue.
The downside is that their recommendations may expand beyond a simple leak repair. If you only want the smallest possible fix, their restoration-first mindset may feel bigger than expected.
Very responsive and informative
Dave and his team did tremendous work installing a sump pump system in my finished basement. Their team was very responsive and informative throughout the process and much more competitive than other waterproofing contractors. Highly recommend!

Philadelphia Foundation Repair & Waterproofing is the kind of contractor I’d keep in mind for bigger, more complicated projects.
They handle residential basements, commercial structures, and industrial installations, so the team seems comfortable with work that goes beyond a small seepage issue.
Their free inspection is a useful starting point if you’re trying to understand a tricky foundation layout before committing to a repair plan.
I also like that their service list covers waterproofing and broader structural concerns, which can save time if your basement problem is tied to shifting or cracking.
The tradeoff is that they also take on large commercial jobs. As such, tiny residential fixes may not receive the same boutique attention you would expect from a small-home-only contractor.
Responsive
It was a pleasure working with Ed and his team. Our basement was in serious need of paint and waterproofing. Ed was straightforward, responsive, willing to work with us on a tight timeline and was extremely professional throughout. Ed and his team turned our basement into a functional storage space. Thank you to Ed, Vince, Bryan and the whole team at Hard Knox / Philadelphia Foundation Repair. We appreciate you.

Truly cares
Ed was extremely helpful as well as knowledgeable about my situation. I’ve been calling around to set up estimates to waterproof my basement and as soon as I spoke with him I felt as though I had come across someone who truly cares. Not to mention he gave me an estimate for tomorrow which is extremely quick especially in comparison to other waterproofing companies.

5. Jamison Basement Waterproofing

Jamison Basement Waterproofing is a strong pick if you want access to proprietary drainage products instead of a basic off-the-shelf setup.
This company has served the area for more than 35 years and is the only authorized iBasement Systems dealer in Pennsylvania, which gives customers access to patented GrateProducts.
I appreciate their closed drainage systems that use wall vapor barriers to help keep soil and debris from clogging the setup.
They also back sub-floor drainage work with a transferable lifetime warranty. That kind of protection feels reassuring for recurring water problems.
Just be aware that regular maintenance for those systems is routed through the associated Sump Pump Geeks network, so ongoing support may involve a separate service team.
Great job
I had Jamison install a new drain and waterproof my back basement. These guys did a great job. Clean work and even arrived early. I highly recommend you use them for your basement needs. Here is 1 before photo and a few after the work was completed.

Excellent job
Hired Jamison to add an egress window, sump pump, and to waterproof our basement. The project manager, Steve, and his crew, were all great to work with. Showed up on time everyday and did an excellent job with all the work. They were efficient, clean and attentive to detail. I would use them again, and highly recommend.
