"Based on the foundation being brick, there was not the option to add weeps. Additionally in the middle of February, I did not want to excavate the exterior. Therefore the waterproofing was done from the inside. Renew added a rigid board covering onto the foundation interior which will direct moisture downwards to the new drain tile system and now the basement is humidity and moisture free. Very pleasant folks to work with too."

"Just a super positive experience overall. We were always kept in the loop on what progress was going to be made in the coming day or week. The workers became friends we looked forward to every day. They turned our sad dungeon basement into a light and beautiful and airy and cozy space we actually want to go spend time in with our tiny kiddos. =)"

"First, Bob [Provider Name Removed] took the time to explain all aspects of what is causing the mold in our crawl space. His explanation was consistent with the mold testing specialist/microbiologist we hired. The options for turning our crawl space into a mini basement were in-line with what our microbiologist said. The installation team was great to work with. They were very knowledgeable, professional, and respectful of our property. They cleaned up all the post project debris too. We are very happy with our fully enclosed crawl space that doubles as lock-and-key storage. We highly recommend the entire Basement Repair Specialists team."

Basement Waterproofing FAQs, answered by experts

In Milwaukee, unexpected costs during basement waterproofing often arise from uncovering deteriorated masonry or hidden cracks in older stone or brick foundations. Utility rerouting may be needed if lines are close to the work area. Restoring disturbed landscaping and hardscapes is common, and moisture control upgrades like sump pump enhancements can add to expenses. Permit requirements and drainage system modifications may also impact your final project scope.

Helpful?

Milwaukee’s frequent freeze-thaw cycles and heavy spring rainfall can intensify hydrostatic pressure against basement walls, making robust moisture control essential. Snowmelt in early spring can saturate clay soils, increasing the risk of seepage. Scheduling exterior waterproofing is best from late spring to early fall, as frozen ground and unpredictable weather in winter can delay excavation and proper drainage system installation.

Helpful?

In Milwaukee, combining basement waterproofing with foundation repairs, insulation improvements, or installing a new drainage system can streamline your project and minimize disruption. If you’re planning basement finishing or yard regrading, coordinating these upgrades can reduce labor overlap and help maintain consistent moisture control. Bundling excavation work, such as radon mitigation or utility updates, often leads to a more efficient and cost-effective process.

Helpful?

In Milwaukee, consider the impact of high groundwater tables and the prevalence of older homes with unique foundation materials. Urban properties may have limited exterior access, requiring creative waterproofing solutions. Combined sewer systems can affect drainage options, and local soil conditions may demand specialized approaches. Planning around contractor availability and seasonal weather ensures your project is completed efficiently and with minimal disruption.

Helpful?

For Milwaukee homes, flexible exterior membranes and polymer-modified coatings perform well against shifting clay soils and freeze-thaw cycles. Dimpled drainage boards help channel water away from foundations. Inside, a high-quality sump pump with battery backup and a reliable dehumidifier are crucial for moisture control. Polyurethane crack injections and flexible sealants provide durable solutions for foundation repairs and long-term water resistance.
