"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

You should take care of any sign of water in your basement, whether it’s dampness after heavy rain or puddles of water on the floor. Besides potentially causing a health hazard, the moisture can damage your home’s structure and foundation. Furthermore, mold can grow quickly and spread throughout the rest of your home. With mold remediation costs ranging between $1,200 and $3,400, it’s best to avoid mold issues by fixing the leak.

In many homes, an unfinished basement is an ideal place for an in-ground pool. The concrete floors, protection against water damage, and access to the ground below your home make this a large contender. Speak with a local basement remodeling contractor to ensure your space is right for the large construction.

External pressure on the basement wall can cause it to bow inward. Soil, heavy with water saturation, is commonly the main culprit. The soil exerts immense pressure on the wall, causing it to fail, at least partially. This is known as hydrostatic pressure—these situations can occur after rainfall or simply due to regular groundwater presence and may be temporary or more permanent.  

Walkout basements cost more than other kinds of basements, and can also increase your risk of leaks as well as a loss of insulation, leading to higher heating and cooling costs. Improperly installed walkout basements may lead to structural issues with your foundation, so ensure you’re working with a contractor who has extensive experience with this kind of basement.

Egress windows or doors are required in finished basements to meet safety and building codes. If your basement is unfinished and used as a storage space, egress windows are not required, but anything considered a habitable space must have an additional point of egress in addition to the stairs.
