"We recently had Mega Power Electric Inc install a solar system and panels. The President and provided excellent communication all the way through the process. He even met with us after installation to explain the almost incomprehensible PG&E bill. Although not the least expensive bid, his was competitive and I felt he was as interested in educating me about solar and the various types of panels and inverter systems as he was in selling a system. He demonstrated how the array of panels would meet our energy needs and as opposed to some of the other companies, wasn't selling us more than we needed. We are very satisfied with our solar system and I highly recommended Mega Power Electric Inc."

"Joshua has done a lot of work for us over the last year - from replacing blinds to fixing faucets, toilets and installing light fixtures, smoke alarms, shower fixtures, etc.  His work is always excellent!  He is very prompt, reliable, and does a thorough job.  I was thrilled to find such a great handyman since we had to move and rent out our house.  The only problem is that his schedule is very busy because he's so good!!

All work was explained thoroughly and the color choices were presented to me. I appreciate  their efforts to be sure I was satisfied with the job and I feel confident in recommending Ultimate Concrete. "

"Ybarra Professional Builders did 2 big plumbing projects on my house and property. Not only did they install a brand-new main water line to replace the old leaking galvanized steel pipe, but they also re-piped my house's plumbing as it was also made from that same rusting out galvanized steel. I also had some other major work done by them at the same time (tree removal and sprinkler repair) but since Home Advisor asked for a specific type of project for this review, I will only review the plumbing projects. Vlad was the project manager for all of these projects. He coordinated all of the sub-contractors' work and got the projects done in a timely manner. There were none of the time issues that I had heard about with other contractors, such as waiting weeks between one phase of a project to get the next one started-after one phase was done, the next phase would begin with no more than a day or two in between. He was very pleasant and very patient with my many questions and concerns and kept me up-to-date with what was happening. The project that I most dreaded, the house plumbing re-piping, was not as bad as I thought it would be, to my great relief. All of the people who I dealt with at Ybarra were pleasant and professional, from the sub-contractors to the office staff. I think the quality of the work performed was very good. In the additional clean-up phase, the holes in the drywall where the plumbing had been re-piped were patched and painted, and the concrete where the driveway had to be cut to replace the main water line was re-poured. This portion of the project was available as an additional cost, but the workmanship was very good. I had heard and read many horror stories about dealing with contractors so working with this group was a pleasant surprise. Thank you, Vlad."

Foundation Repair questions, answered by experts

You can seal a concrete slab by cleaning the surface, filling in any cracks, etching the surface, applying a sealer, and letting it dry. Concrete slabs don't typically need sealing, but you can use a topical concrete sealer if you notice signs of water damage. If you haven't already fixed the cause of the leak, then you'll want to repair the plumbing before you seal a concrete slab.

If foundation problems are not fixed, they will likely worsen over time, leading to more complex and expensive repairs. Neglecting a damaged foundation can cause a range of issues, including:

  • Structural Damage: Minor problems like small cracks can escalate into major structural issues. This can damage the house above the foundation and, in severe cases, lead to foundation walls caving in or a total collapse.

  • Water Damage and Pests: Moisture and water intrusion can cause flooding, mold growth, and pest infestations.

  • Health and Safety Risks: Mold can lead to poor indoor air quality and other health risks, while structural instability poses a significant safety hazard.

  • Reduced Home Efficiency: A compromised foundation can negatively impact your home's energy efficiency.

To avoid these escalating problems and costs, it's best to hire a foundation repair company to address any issues as soon as you become aware of them. The earlier problems are discovered and fixed, the lower the repair cost will likely be.

The best way to determine if ceiling cracks are structural is to hire a ceiling contractor to inspect the cracks and provide a professional opinion. That said, you might be able to make an educated guess based on the size and appearance of the crack. Larger cracks, cracks accompanied by sagging or discoloration, and cracks that travel from the ceiling down the walls are all signs of structural issues.

If your building department catches you or a contractor doing foundation work without proper permits, they will likely put the work on hold until you secure the necessary permits, which can cause delays of days or even weeks. You can also face violation charges for construction without a permit, which can cost hundreds, depending on where you live.

Underpinning is a specific type of foundation repair where a specialist installs deep piers under a foundation to provide additional support. This method is often used when the soil beneath the foundation can no longer evenly support the structure. Foundation repair is an umbrella term that includes many methods. Besides underpinning, other common repairs include foundation crack repair, waterproofing, cosmetic repairs, and concrete block wall stabilization. Often, underpinning is accompanied by other work to address the root cause of the foundation issue, such as regrading the yard to ensure water drains away from the house.
