"Patrick with Farmhouse Construction did excellent work rebuilding my deck. This deck is off a 2d floor bedroom and has steps in between 2 levels. His measurements were precise and the wood (I believe fir and cedar is beautiful). He proactively explained his process, how he worked, any anomalies or unusual things he encountered and always answered my questions. He communicates very well. His work is outstanding and I would hire him again. I chose to stain the deck myself. Patrick spent a lot of time explaining the process of staining, the nuances of different staining products and applicators he recommended. He is great and cleaned up the old discarded wood and debris very nicely."

"They leveled our patio and we were extremely impressed with the professionalism of the crew. Unfortunately, the patio sank a couple of inches within a month and they returned again, at no cost, and re-leveled. We are hoping that it will stay but, whatever happens, it is not the fault of their expertise but rather the ground continuing to shift. That is our personal assessment."

"I will surely recommend Diversified! I was concerned that our home had a mold issue and the related health issues it brings. Ray carried out a free inspection for us as early as he could. Then he walked me through the mold removal plan step by step. I really appreciated the knowledge that he shared with us and the overall service he offered us to do mold remediation from our house. Glad to recommend this company for attic and crawlspace mold issues."

House Leveling questions, answered by experts

Most states and municipalities don’t require concrete mudjacking companies to carry a specific license, but they usually need to have a general contractor’s license, and they should be fully insured. The only exception is if the mudjacking company provides foundation repairs as well, or if it offers mudjacking for home foundations. In that case, they will typically need a foundation repair contractor’s license. You can check state requirements and then use Angi’s license lookup tool to confirm that a company is properly licensed to provide mudjacking services in your area.

A good slump height really depends on the project, but there is a use for nearly all slump levels. For example, low slumps are best in projects that require structure, such as curbs and roads. High slumps often require additional reinforcement, but they flow more freely into hard-to-reach spaces.

Pros often use mudjacking or polyurethane foam injection to level a sunken concrete patio. Both methods lift the slab by filling voids beneath it. After properly compacting the soil beneath it to prevent future settling, the concrete may need to be removed and re-poured for severe sinking.

On average, a mudjacking repair lasts between five and 10 years, though it can sometimes last for well beyond a decade under ideal conditions. Its longevity depends heavily on several factors, including the condition of the underlying soil, environmental conditions like freeze/thaw cycles and erosion, and whether the root cause of the sinking, such as drainage issues, is resolved. Because it doesn't always fix the underlying problem of loose soil, mudjacking is often considered a temporary solution. Proper maintenance and evaluation can help extend its lifespan.

The timeframe is generally a few hours, allowing for immediate use post-hydration, ensuring minimal disruption to surrounding activities.
