"Outstanding, Andrew took general guidance of what I wanted and came up with a solid plan that included a larger patio, room for a hot tub, built a great looking grill surround, tied patio into gazebo and great looking landscaping around patio and new fence. Received numerous quotes. Eql was lowest priced by 15%-20% and highly rated. Recommend them for all landscaping and hardscaping needs. Quality of work was superior to anything I have had done in the past at lower price"

"

We've lived in this (55 year old) house for the past 12 years, and we've always had to deal with a periodic water problem in the basement. and wet weather exacerbates the problem. A few months ago things became much worse when our poured cement foundation developed three leaks, allowing water to flow freely into the basement. I called in four or five contractors to recommend a solution, and I was most impressed by Adirondack's analysis, which actually called for less work than most of the others (and of course, less money). The other contractors all insisted that a floortile system be installed to direct water into a new sump system, but Adirondack felt that our existing French drain would serve that purpose. They installed their "Super Sump" system, piped outdoors into a bubble pot. Repairing the wall cracks wasn't possible due to the deteriorated condition of the cement, so they recommended BrightWall panels, which served two purposes: they cover the ugly walls (and brighten the basement) and force any leaking water directly below into the French drain.  I've deliberately waited until now (six weeks later) to write this review because I wanted to get an idea of how their system would work. I'm happy to say that the system has worked beautifully.

I'm very happy with Adirondack. They were very professional to deal with, their estimator was experienced and didn't try to sell me the moon, and their work crew and job site supervisor were great.

Masonry FAQs, answered by experts

For most brick cleaning jobs, including fireplace bricks, use a masonry sponge and a gentle cleaner. A simple solution of equal parts water and vinegar, or a few drops of dish soap in a bowl of water, can effectively remove grime. For tougher stains, you can use a dedicated masonry or fireplace cleaner. It is crucial to wet the bricks thoroughly with water before applying any cleaning solution to prevent the brick from absorbing it, and to rinse the surface completely afterward. Harsher cleaners containing bleach or ammonia should only be used as a last resort, and they should never be mixed together.

Mortar is a mixture of sand and cement that binds materials, such as bricks, stones, and concrete blocks, together. Think of it as the glue that fills in the gaps between bricks and stones, then seals them in place to prevent damage or deterioration. Mortar also helps spread the load across a wall or structure, keeping cracks and shifting at bay.

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.

Landscape boulders, especially porous stones like sandstone or granite, can crack or break over time. Cracks occur when water seeps into the surface of the stone and freezes. The risk is highest when it rains during the day and temperatures freeze overnight since the moisture has time to penetrate deeper into the rock before expanding.

While painting can certainly change the look of a chimney, you should think twice about giving your brick chimney the old landlord special.

Painting brick is porous, meaning it’s full of tiny holes that can soak up moisture. Those holes also allow it to dry, though. So, when you paint it, you trap any moisture inside, providing an opportunity for mold, mildew, and water damage.

Paint also shows wear faster than naked brick. This means that once you paint a brick surface, you’ll have to keep painting it to maintain a clean look. A paint job is also harder to undo on brick because of its porous nature. Once you paint it, it’s hard to go back without some serious power washing—another added cost.
