We've been serving York County and the Seacoast for over 25 years. Fully insured. All work is warrantied. We take half the quote amount up front and half upon completion. We will also give as many recommendations from brick yards and customers as needed.

"One word: Don't. They replaced the top 6' of our chimney about 7 years ago as well as parging and sealing all of our chimneys and the new chimney is literally falling apart in chunks, the joints are seeping water, and the parging is flaking off. Besides that, while these two jokers were here (and we weren't) our neighbor told us that they were arguing and throwing chunks of concrete at each other. We also found that rather than haul the old chimney pieces away they hid them in the brush beside our lawn. Also, forget about a warrantee. That is B.S."

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 Waterproofing questions, answered by experts

Sandbags are the most common and efficient way to create a flood barrier at home. Some local authorities pass them around to homes before the risk of a flood. Otherwise, you can use flood-proof house materials, like burlap or woven plastic bags, to make sandbags and fill them with sand or cat litter. Make sure that when you stack them, they’re tightly laid on top of each other, creating the effect of a firm wall against accumulating water.

Finishing an unfinished basement adds the most value, with an average return of 70% or $22,400. A bathroom addition in the basement will provide an ROI of 75%, but the higher cost will leave you with a lower actual return of $9,000, on average. Finishing a basement and adding a kitchen, bathroom, and bedroom to rent the space will leave you with the highest possible ROI, as you could see well over 100% if you rent the space out long-term.

Several factors dictate if you should waterproof the interior or exterior of your basement. Waterproofing the exterior of your home is a great option if you use your basement for storage, as it provides the most protection from water and water damage. If you prefer work done outside of your home versus inside, exterior waterproofing is best for you. However, interior waterproofing is often less expensive since the area is easier to reach and requires less labor.

Generally, moisture barrier padding costs $0.75 to $1.50 per square foot, varying by brand and mix. That’s a lot more than standard padding, which runs $0.25 to $0.90 per square foot. The price difference between these two options might seem steep, but think of it as insurance against future carpet replacement costs and subfloor damage. If you have pets or kids, that extra investment in high-risk areas like your living room often pays off.

Water damage to a foundation often starts as a slow leak or water vapor problem that worsens over the course of months or even years. The speed at which foundation leaks worsen depends on a few factors, including your climate and location, the soil composition around your home, the foundation drainage system you have in place, if any, and the type of foundation you have. Even if you have a minor issue that’s slow to develop, it’s best to have a professional address the issue immediately.
