"Jeff and his team did an outstanding job on our roof. They use high quality materials, warranty their work and are cost competitive. The team tore off our old roof (2 layers) and replaced it with new architectural shingles the next day. They cleaned up each day and were vigilant in chasing down any roofing nails that may have landed in the yard using a magnetic sweeper. They worked with us to get the 2 hot water solar panels decommissioned and removed them from the roof as part of the job. The house looks better than ever and we couldn't be happier with the work. We would use them again and will wholeheartedly recommend them to anyone doing general contracting or roof replacement."

Foundation Repair questions, answered by experts

While it can be difficult to identify a bad foundation at first glance, look for large horizontal cracks, discoloration, bulging basement walls, or signs of water damage. You may also see large gaps between the home and the foundation on the outside or signs of pooling water from a recent storm.

The best solution to fix a foundation crack in your basement floor depends on the underlying cause. If you just have hairline cracks from settlements that are no longer growing, the best option is to seal them with a crack sealant. If the cracks continue to grow, one edge rises above the other, or there are signs that water is getting in through the crack, a professional repair will be necessary. Depending on the root cause, your professional may employ foundation underpinning or some other type of stabilization, seal the cracks, or install a drainage system.

The foundation repair that will work best varies based on the extent of the damage, the underlying cause, soil conditions, weather conditions, and more. Permanent foundation solutions like underpinning and exterior drainage solutions are better than temporary fixes that don’t address the source of the issue. Some examples of more temporary solutions include mudjacking or slabjacking, waterproof paint, and dampproofing. The best course of action is to have a reliable foundation specialist inspect your issue, treat the underlying problem, and restabilize your foundation.

Depending on the severity, a slab leak can go undetected for months or even years, especially if you don’t carry out routine foundation inspections to find foundation leaks early. However, minor leaks are likely to turn into more severe leaks over time, so you might notice increases in water bills and issues with yard drainage, even if the problem is minor.

Some foundation repairs are permanent, like underpinning and exterior drainage systems like the French drain. These fixes address the underlying problems—insufficient support from the soil and hydrostatic pressure on your foundation walls, respectively—so they can last for many decades, making them “lifetime fixes.” There are other solutions to address these issues that will last for up to a decade, making them temporary. These include slabjacking to raise concrete slabs back into place and dampproofing to reduce the water in the soil that interacts with the concrete foundation.
