"Groundworks were contracted to encapsulate the crawl space, with a dehumidifier, intellijacks & sump pump. The inspector showed us pictures & videos of what the work would look like on completion, & explained how each solution would be installed. They tried to charge me more for vent covers until I showed them the contract covering this part. The foreman told me there was a reset button for the sump pump to be installed on an exterior wall, but they did not install it, instead said they would put in a service order. I haven’t heard anything about this issue yet. When they installed the moister barrier, they excluded the cement pads I was told it cost extra to have them covered. When I signed the contract, I was never told there would be extra charges for vent covers or cement pads to be covered. The contract I signed covered a complete encapsulation, but this is not what I got. This is a bait & switch. I would not recommend Groundworks."

"Rafael and his crew were amazing to work with. The initial visiting for a quote was free and very informative. He was quick to understand my sketches for a totally different deck design, asked really helpful questions, and gave clear recommendations. They were able to start promptly. All of the crew members were very professional in their communication and planning and updates. They were highly skilled and did excellent quality work. I am so happy with my new deck! When work was done, they honored their quoted price. For my project they did not ask for any payment upfront, just payment in full upon completion to my satisfaction. They do take other payment methods but prefer cash so I suggest you ask about your payment options upfront. For the whole process, this company was great to work with. The craftsman of the finished work was excellent quality. I recommend them to everyone."

One yard of concrete covers a different area depending on its thickness. At four inches thick, one cubic yard of concrete covers about 81 square feet. If you're pouring at five inches thick, it covers around 65 square feet. For a six-inch thickness, expect it to cover approximately 54 square feet. The thicker your slab, the less area one yard of concrete will cover.
The shelf life of concrete depends on whether it's wet or dry. Ready-mixed concrete in its wet form lasts approximately 90 minutes to two hours after water is added, so it is essential to schedule your delivery carefully. Bags of dry concrete mix can last several months if stored properly in a cool, dry place. Moisture exposure can cause the cement to harden or lose strength over time.
An average concrete truck can hold between eight and 11 cubic yards of concrete, although some larger trucks can carry up to 15 cubic yards. However, road weight limits often restrict the amount they can carry, so most deliveries are around eight to 11 cubic yards. Knowing this helps you plan the number of truckloads you'll need for your project.
Pouring concrete doesn't take very long once the truck arrives. One cubic yard of concrete can be poured in about 10 minutes. Therefore, a full truck with 10 cubic yards of material would take approximately one hour and 40 minutes to empty. Keep in mind, though, that preparation and finishing work add time to the overall project.
Concrete sealing costs between $1,400 and $3,000, depending on the area's size and the type of sealer used. Sealing your concrete creates a protective barrier that blocks moisture and chemicals, helping to extend its lifespan and maintain its appearance. Investing in sealing can save you money on future repairs.
Concrete walkways cost an average of $1,800 for a standard 200-square-foot installation. This includes materials and professional labor to create a durable and attractive path. The actual price may vary depending on design, finishes, and any additional features you select, but it's a worthwhile investment that enhances your home's curb appeal.
