The estimator arrived at our home at 8:00 AM on a Saturday morning, as had been previously scheduled.   He examined the project, made thorough measurements, and followed-up with a comprehensive, written estimate and schedule for the project.  He mentioned the various stages of the project:

First Visit

(1) Removal and disposal of the old surface.

(2) Removal of approximately 270 feet of Belgian block curbing and preparation of the curbing area for the reinstallation of the Belgian block in a new cement base.  This was done ever so carefully so as not to damage the Belgian block during its removal.

(3) Repair of the driveway subsurface drainage (which had been poorly done when the home was built).

(4) Preparation of the driveway gravel subsurface.


Second Visit  (Three weeks later ... arriving on the day and time scheduled at the start of the project).

(1) All Belgian block curbing was carefully aligned and reinstalled ... in a proper cement base for long-term stability.

(2) This was done with minimal invasion of the lawn area behind the Belgian block, and without any damage to the many plantings running the length of the Belgian block curbing .


Third (and final visit ... two weeks after installation of the Belgian block).

(1) Again the crew arrived on time (on the day and time scheduled at the start of the project).

(2) They resurfaced the entire driveway with asphalt  ... leaving the work area pristine with temporary barriers to prevent anyone from inadvertently driving on the surface while it dried and cured over the next  several days.


During the entire project (from the original call for an estimate, to the final steps) the management, office staff and crews were professional, polite, competent, and always on-time ... doing what they said they would do when they promised.

If we ever have need for a similar project, I would not even bother to get competitive bids.  I would simply call SILVERIO and trust them with the job.  Their work, communication and customer service were impeccable.

"Great working with Angelo and his team. They did a fantastic job of repairing pool leaks, coping, tile, and completing the area around the pool. They cleaned up after themselves, were approachable, hard-working, and courteous. I will hire them again!"

He and his crew are both skilled artisans and artists. He is polite, honest, and hard-working, and his services, quite reasonably priced, are worth every penny spent. Hire this man."

"John and his team did a great job. We contacted them to fix concrete steps in our back yard leading to our deck and he was able to provide all options for replacement, costing and timing. He was very respectful of when we wanted to get the project done and I felt like he knew exactly what needed to be done. I would highly recommend John and his team to anybody who needs masonry work."

"We hired Budget Dry to review our basement problems and hired them to do the waterproofing project, install new basement windows, install the Santa Fe dehumidifier, and recently they installed our back-up battery system. We highly recommend them -always courteous, get the jobs done quickly and neatly, and always respond when we need their advice/want to purchase new filters. A great company!"

Concrete Repair FAQs, 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.

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.

Whether you need a permit for foundation repair depends on your location and the scope of the work. Major repairs like foundation stabilization typically require a building permit, while smaller projects such as sealing non-structural cracks or applying waterproofing solutions often do not. It's crucial that your contractor follows all local building codes, as an inspector will review the work to ensure it's up to standard. Failing to obtain the necessary permits can create issues when selling your home and may lead to further damage if the work is not done correctly. Your foundation repair specialist will usually know if a permit is needed and can handle the process for you. You can also contact your local building department or municipal office to confirm the requirements and verify that your contractor has filed the appropriate paperwork.

Common issues with concrete that may require professional repair or resurfacing include cracks, spalling, uneven surfaces, and weather damage.

You can patch minor cracks and damage yourself using concrete fillers or mortar. Larger damage may require full replacement of affected slabs. However, water damage to your concrete will never disappear unless you address the root cause causing the water to cumulate. To prevent future damage, you can also waterproof your concrete.
