JJ is rare. This guy lives to do the right thing, the right way, and the right fix. He is passionate about foundations and doing an amazing job. JJ was early every time, his crew worked their rear ends off, and they left a clean site no matter what. JJ is by far the best foundation expert and worker I’ve ever seen in this business. You’ll never find better. I hired him to fix my disaster of a basement and they were absolute perfection from start to finish.

I want to tell everyone about the outstanding service I have received from JJ Enterprise.​ From my initial call to request a quote until the job was complete my expectations have been far exceeded! The entire staff was helpful and friendly, they also cleaned up all of the debris each day. They offered ideas and suggestions that I had never thought of and I felt zero pressure to do anything they suggested. I would highly recommend them to anyone and I love the new high quality sidewalks and driveway they put in for me!

Milwaukee Structural Experts

We service all of Southeastern Wisconsin:

Our Milwaukee Structural Services

Structural construction or repairs to a building is crucial for the safety and longevity of the structure. Here’s a few common structural services we can do, but we are also available for others if needed. 

1. Foundation Jacking. To fix a sinking foundation that was installed on inefficiently compacted dirt, we use a jack to correct the slab’s position and pumping additives beneath it for stability. This process saves you from having to replace the slab altogether and won’t damage any surrounding landscaping or interior structures.

2. Structural Welding. Our certified welding team can help during new construction with structural welding requirements. We help general contractors in a pinch and also can handle the structural component as the main contractor. We work with both residential and commercial clients on any structural welding needs. 

3. Foundation Underpinning. Underpinning is a popular method of reinforcing a foundation with cracks wider than ¼”. Underpinning either increases the depth or the surface area of your foundation so that it reaches more solid soil or to distribute the load across a wider area, respectively. The most common method of underpinning is a mass pour. We’ll excavate certain sections to a pre-determined depth below your foundation’s footings, then pour concrete into the area to support your foundation.

4. Foundation Wall Reinforcement. If possible, we will always try to save the existing foundation walls. It’s easier and cheaper than a full replacement. The reinforcement process can vary depending on the situation, but most often we see a similar situation. The walls are bowing in from improper drainage and need to be pushed back outward. We use equipment to temporarily take pressure off the foundation and push the wall out. Then we’ll leverage steel beams to reinforce the wall structure so it won’t bow again. Then, we’ll re-grade your exterior to prevent the issue in the first place. 

5. Foundation Wall Replacement. A wall replacement becomes necessary when your foundation’s walls are too old or have significant damage that a repair can’t tackle. We’ll build a temporary framework, remove soil around your foundation, dismantle the deteriorated walls and footings, put up a new, structurally sound wall, and then remove our temporary support. This process causes minimal disruptions to your daily life and is the most efficient route of replacement. 

Whether you need structural reinforcement, repair, or realignment, we’ve got you covered. We’ll tackle any faulty or unsound structural elements of your foundation walls, ceiling, and floors to ensure that your home or commercial building are supportive of everything above-ground. ​

What Can Cause Damage To Require Structural Work?

There can be any number of reasons the structure can require repairs. Some commons ones are:

  • Water damage
  • Age
  • Faulty foundation installation
  • Poorly impacted dirt
  • And more

Signs Your Foundation Walls Need Attention:

  • Uneven floors and slanting
  • Cracking walls or ceilings
  • Gaps underneath baseboards
  • Cracked brickwork
  • Door and windows become stubborn and won’t open properly
  • Sunken concrete next to your foundation
  • Bowing walls

We specialize in structural realignments, reinforcement, repair, and framing to ensure that we fix the problem and prevent future issues all in one go. Nearly every basement in Milwaukee will one day face one of these issues, so you make sure you know who to call when things go wrong!
