"Our sewer service between the city and the house failed due to poor materials when the house was built in '95. Once it was all exposed, it was easy to see what a poor system a less caring plumber had installed. Vince and company replaced it all quickly and easily with the proper materials. We use Vince exclusively for all of our plumbing needs."

"Well. 1st plumber who looked at the system said shower valves needed to be replaced but that was a problem because there are no access panels. Chaub plummer advised valves were good quality and there was no need to replace. He replaced/installed new hardware and did a great job in a timely manner."

"I had a major drain blockage that was backing up into my home, and Mountain Edge Plumbing came to the rescue! They were quick to respond, professional, and clearly knew what they were doing. They explained the issue, cleared the clog efficiently, and even gave me tips to help prevent it from happening again. Everything is flowing perfectly now. Highly recommend them for any plumbing issues—top-notch service from start to finish!"

Basement Waterproofing questions, answered by experts

Water damage to concrete is often gradual and can take months, if not years, for a concrete structure to be fully destroyed. The process often starts with cracks on the surface, followed by sinking slabs and eventually crumbling cement. Therefore, it is important to repair minor damages early to prevent the situation from worsening.

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.

Yes, outside leaks can easily cause damage to your home if you don’t have waterproofing measures in place. Regularly check your property for signs of a leak, ensure your home’s landscaping is at least at a 5% slope, your basement windows are sealed, and you have an aligned gutter system to catch rainwater.

Yes, cleaning a crawl space is worth the cost. Although it's an out-of-sight area, neglecting it can lead to significant problems like pest infestations (including termites and carpenter ants), mold, and fungal growth, which can cause structural damage. Regular cleaning helps prevent these issues. While hiring a contractor has ongoing costs, the price for cleaning—typically between $0.50 and $4 per square foot—is much lower than the cost to remediate a pest or mold problem. Additionally, a clean crawl space can lead to improved indoor air quality and more comfortable temperatures in your home.

Yes, slab leaks are fairly common, especially in older homes and places that are prone to earthquakes which can move home foundations.
