I am a newly started hardscape business owner with over a decade of experience. Looking to provide a great service and experience at the best cost possible. Our specialties are, but are not limited to Walkways, Patios, outdoor living spaces

"After meeting with multiple contractors, East Gate Hardscape was chosen as the contractor of choice for out patio/walkway project. Being budget sensitive i had concerns about the cost and viewed it as being "nice" to have but can we afford it ?? After talking with East Gate and their proposed price, that "nice" to have patio/walkway became reality. As the project ensued I was pleased as the homeowner to see the attention to detail and the care taken to get the job done right - seeing this I knew I made the right choice. We are very pleased with the final product and it didn't break the bank !!! East Gate comes "highly" recommended !!!"

"Basement Improvements waterproofed my basement and poured a new concrete floor. Both my basement steps were ruined by Basement Improvements, LLC. I have steps from my garage to the basement that they removed and destroyed. They also ruined the step from my house to the basement by cutting the steps instead of putting the concrete around the step. They cut the steps 2" high. They also buried the lines from my oil tank and heater in concrete. I filed a complaint with the BBB and expect to be reimbursed. The communication was incredibly poor throughout the entire process. I did not know my steps would be cut or that my lines from to the oil tank and heater would be buried in concrete. Nothing about the process was communicated to me until I asked a series of process questions. My questions about the process were treated as a burden. It was never communicated to me that my steps would be cut. It was never communicated to me that my connections would be buried under concrete. It is never communicated to me that my steps up to the garage would be damaged. I regret using Basement Improvements and wish I had chosen a more professional and responsible business. I regret not choosing TC Hafford. I choose Basement Improvements because the cost was lower, but with all the poor workmanship, my cost is higher. Don’t make the same mistake I made, choose a professional company to do this work."

"This company may not be for you. After they blow in insulation the holes they made, in my case, were not adequately filled and then mudded over. Now my painting contractor wants a fortune for a drywall company to come over and re-do the job so it can be painted without the big sunken, underfilled holes showing through. Be sure you specify what you expect so that when you paint it will look as you'd want your home's ceiling to look."

Basement Waterproofing questions, answered by experts

A walkout basement is considered to be partially below grade because at least one wall is entirely exposed. In some cases and in specific municipalities, inspectors and appraisers will still count walkout basements as below grade, which means the space can’t serve as living space or be rented out. If you intend on using the area as living space or a separate apartment, you should check with your local building department to make sure it’s legal to do so.

Standing water under your house can threaten its structural integrity. If water pools in your crawl space, it can damage the foundation and the structure above ground, causing wood rot, mold, and other problems. If you have a concrete foundation, standing water under your house can also make your foundation slabs crack.

The best way to ensure the ground next to your home’s foundation drains properly is to divert water away from it as much as possible. While a flood wall can stop water from entering the house, gutters and spouts can help direct rainwater and melting snow away from the foundation. Keep your gutters as clear as possible from dead leaves and other yard debris so they can effectively divert water from your house. Add extenders to the spouts so the water runs out and away from your home, not into the surrounding soil.

If you don’t wish to dig it out and convert it into a finished basement, you can still encapsulate your crawl space to protect it from damage for an average cost of $5,500. Finishing a crawl space beyond this isn’t really worthwhile, as the low ceilings mean you won’t be able to use the area as living space.

The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in. 

If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.
