And we would HIGHLY recommend this company to others! THANK YOU AJB CONCRETE FOR AN AMAZING JOB!!"

"Erinn was my initial contact and he gave a very through and fair estimate. We had structural work done to support floor joists and large beams under the garage that needed replacing. Ernesto and his team, Julio, Salvatore and Gilder worked tirelessly to complete the work and were respectful, punctual, informative and good humoured throughout the entire process. I would not hesitate to use them again or recommend them to others. A really great company!!"

"**SIMPLY OUTSTANDING** Robert Garcia Concrete is the only company, in the past 3 yrs that we hire. During this time, Robert and his crew have completed 3 jobs for us. Everything from our first conversation about the upcoming project is fully estimated in detail and documented in both email and text by Robert. His attention to customer service is beyond compare. The cost is very fair. The level of perfection that the entire crew puts forth is really enjoyable to witness. Our most recent project was a concrete patio replacing a preexisting. wooden deck that, over the years was in disrepair. Robert and his crew demo'd the structure in short order, leaving a clean area. The next morning they installed rebar and forms. The next day they were here bright and early w/ concrete pump, truck, and in no time had the new patio slab looking fabulous. Robert himself, always returns the following day to remove forms, and check to ensure all is well. An impressive part of this project was the replacement of a small narrow set of precarious stairs with risers that were too high and too shallow. They completely transformed the area by removing the old, and made all new safe and aesthetically symmetrical entry to our family room from the backyard patio. These guys are top shelf! Friendly professionals. And...they play great music while they work, which makes watching the evolution to the area that much more enjoyable."

"Javier installed a new fence and custom gate. The work was started on time and completed on time at the quoted price. His crew was neat, clean and easy to work with. We have had him do a couple of other small jobs for us, and have been very satisfied with all of his work."

"The crew did a great job. It took a week to finish due to some rain. The price was fair, as I compared it to several other contractors. They were not the lowest ones, but definitely not the highest ones. Roger was always available over the phone. The crew and leader, Juan, were very professional and courteous. I'd recommend them for sure."

"I hired Dalinghaus Construction to install two push Piers for a freestanding column/wall (bad clay soil causing movement). I meet with Kevin to go over the scope of work and he explained everything in detail. The price was the best I can find. Took one extra day to finish the work, but they did not charge me any additional fees. 3 month later, I had a feeling that the column/wall is moving again and call Kevin. He show up in a few days and show me there is no way that wall is still moving and he was right. They are very good at what they do and customer service is the best. Thank you very much."

Masonry questions, answered by experts

Do not use super glue to hang lights on brick unless you want your lights up year-round. Hot glue is a better choice because it’s easily removable with a small amount of rubbing alcohol. Super glue is very hard to remove, and you could tear off parts of the brick in the removal process.

Yes, it is essential to prime or seal a brick fireplace before painting. Brick is a porous and highly absorbent material, so without a primer, paint can seep into the surface, resulting in uneven coverage and allowing the natural brick color to show through. To avoid this, apply one or two coats of a masonry primer. The primer will seal the brick and provide a smooth, uniform layer for the paint to adhere to. Ensure the primer is completely dry before applying the topcoat of paint.

It is possible, albeit a lot slower, to break up a rock using water. You would do this by freezing and thawing the water. You could create some initial holes or cracks in the rock, then pour water into the cracks or holes and allow them to freeze (so it's best to do this in winter or in colder climates). Since water expands when it freezes, this puts pressure on the inside of the rock and causes it to crack. You could continue to pour more water in and let it freeze to continue to break up the rock.

In some cases, black stains on brick are caused by organic substances like algae and mold. However, it's more likely that the black spots you're noticing on your bricks come from carbon from vehicle exhaust or soot. Black stains can usually be removed by scrubbing the brick with a brush and masonry cleaner or power washing.

Painted exterior brick does not usually need sealing. Brick is a porous material, so you don’t want to apply a sealant that could trap moisture inside the bricks and cause erosion and structural damage. The risk of moisture-induced damage after sealing is higher in colder climates where trapped moisture can expand if it freezes. On the other hand, it makes sense to seal really old brick or kitchen backsplashes, where moisture from cooking can weaken the brick.
