"The Groundworks folks (formerly Bay Area Underpinning) applied their foundation-underpinning technology and expertise to extend to bedrock, level, square up the foundation for an extensive house remodel. I was most impressed by the young man onsite supervisor, Josh who answered all my work done, how and why questions. I wish this info was provided up front by the estimator. (My design-build remodel contractor referred this company)."

"We worked with Ali (sales manager) and Tony (project manager), who took the time to design a project that made sense for our property and our budget, made a number of suggestions and recommendations and were never pushy or tried to "sell" us on something. The crew really went above and beyond to provide top quality workmanship and overall we were in very good hands. Highly recommended!"

"Drew from Legacy Plumbing came out IMMEDIATELY to our rescue because not only were all toilets and showers unusable because water would flood downstairs but we had a birthday get-together with family happening within the hour. Drew was very knowledgeable and quickly fixed our clog and we needed a replacement part for an obvious leak. Legacy Plumbing is super honest, and you don't feel like you're getting ripped off with unnecessary b.s.. This is the second time we've called and because of the great job he did on our last major issue with our old pipes, we called him again. The cleanliness, effeciency, and honesty of this company is why I felt compelled to rave about them and let people know in a review. Definitely my plumber and business to recommend from here on out."

"I had to reschedule our original appointment date. Omar was understanding and we rescheduled to another day that fit my work schedule.  Omar and his son arrived on time and ready to work.  We did a tour of all the varied work I wanted done.  We began in the garage because I wanted to direct how I wanted the garage organized.  We worked well together.  Omar made some good suggestions and listened to what I preferred as well.
In the house Omar had all the tools to check out lights in both bathrooms and toilet.  He had the equipment in his truck for master bathroom lights and toilet.  He needed to replace the light ballast in guest bath which required him going to a couple of hardware stores to find the right fixture.  While Omar worked on lights and toilet, his son and I worked on assembling the curio cabinet and mirror.
Overall it was a very good experience and I will continue to use Omar to help around my home.

"We had to call twice for 2 separate issues and Eduardo was quick to help both times. He was able to fix our issue on same day or within a couple of days. Our sink repair also looks much cleaner than whoever repaired recently!"

Basement Waterproofing questions, answered by experts

Living in a finished basement is acceptable, but only if the space has the proper points of egress and includes smoke and carbon monoxide (CO) detectors to ensure the safety of the occupants. A good way to ensure your finished basement is suitable for use as living space is to get the basement finishing project properly permitted.

Underfloor insulation alone will not cause moisture and mold, but improper installation can. Although the purpose is to seal any drafts, your subfloor still needs ventilation. If you seal the area too tightly and prevent all airflow, this can cause moisture to get trapped. This moisture eventually leads to mold and—if your floors are wood—rotting.

Preventative measures, such as maintaining drainage systems, installing sump pumps, inspecting roofs regularly, and crafting comprehensive emergency plans, can help mitigate future risks.

Ductwork sweats due to a temperature difference between the air inside the ducts and the surrounding air, similar to how a cold drink develops condensation in the heat. This sweating is a sign that your HVAC system is not operating at peak efficiency. The best way to keep ductwork from sweating is to wrap it in proper insulation, which also improves your system's energy efficiency. Another option is to close off your crawl space and install a dehumidifier to dry the air and lower its dew point.

You don’t always need to install a dehumidifier in your encapsulated crawl space, but it might be a good idea in certain instances. If you notice obvious signs of condensation, mold, or musty smells permeating from your crawl space, a dehumidifier can help. It’s ideal for homes in humid areas.

In a worst case scenario, structural damage like rust on metal beams, rotting wood, and swelling on doors and windows can signal moisture problems that would benefit from a dehumidifier.
