"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 !!!"

Local Relationships. National Resources. Call us today! Or email us at [email protected].

"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

The difficulty of adding a basement to an existing house can vary depending on the house’s location, the size of the basement, and the type and condition of the existing foundation. Adding a basement is a job best handled by the pros, so you’ll need to enlist professional help for this project.

Yes, if your crawl space is prone to humidity, a dehumidifier can help keep it dry. For use in a crawl space, you’ll need a high-capacity and high-efficiency dehumidifier with built-in air filtration. It’s also wise to purchase one with a self-draining feature. Otherwise, you’ll need to climb into the crawl space to empty the dehumidifier.

Unfortunately, mold can grow pretty much anywhere, on any kind of surface. However, you’re most likely to see it in damp areas like basements or bathrooms, as well as anywhere there has been a water leak. Consult a local mold specialist to determine if certain areas of your home are prone to mold based on climate and other factors.

As the first layer of water protection for your roof deck and the building materials below, underlayment is designed to prevent water damage, so it’s okay if it gets wet. However, you shouldn’t rely solely on underlayment for protection. If rain interrupts your roof project and you have all of the underlayment down, you’ll likely be fine, but you should install shingles over that layer as soon as possible, as long-term exposure can lead to water damage.

The best way to waterproof a basement is to install a properly functioning gutter system and a French drain around the outside of the foundation. The best solution for your home could involve other waterproofing methods that resolve the problem unique to your situation. Depending on your soil type, climate, and other factors, that could include sealing, landscape alteration, interior drainage systems, and more.
