We had a hot water heater installed today. A couple hours later I was in the basement and smelled gas. Called dispatch after hours and they sent Derrik who quickly found the leak and sealed it off. I would recommend IT Landes to anyone. Thanks.

This is for a rental property I own. I contacted PlumMedic and described the issue. I told them my tenant would call to arrange for them to come out. They repaired the leak and then called me the next day for my credit card for payment. I did not want to have my tenant pay.

"We were in the process of renovating our apartment and needed to apply for permits from the government, which required an architect-signed design drawing. Anthony came highly recommended. He took the time to visit our apartment and carefully understand the challenges we faced in obtaining the permits. After thoroughly reviewing the space and listening to our renovation ideas, he assured us that the project would be straightforward for him and that he could provide an architectural drawing that would not only meet our needs but also ensure we could pass inspection without any issues. Despite the project being relatively small, Anthony was more than willing to take it on and offered a very reasonable fee for his services.

"Bad Experience. Bait and Switched us. Told us the no more than cost of our removal verbally and then said he needed $4k to do the design with us and get final firm contract after that. I told him I was skeptical giving him $4k and then have him come back with contract stating it would cost a big percent more. He assured me “he is not that kind of guy”. Then after the design and a smaller scope he wanted to charge us 30% more. Took our money and we now have to start over with a new contractor."

FAQs for basement leak repair projects in Harleysville, PA
The cost to finish a basement is $18,400 for the average homeowner. However, this cost could be as little as $2,800 or as much as $34,500, depending on the basement size and the materials needed. If your basement is already outfitted with electrical and plumbing, expect the cost to fall on the lower end.
For example, the drywall cost for this project averages around $1,750, but other features, like hiring a plumber, cost between $45 and $200 per hour.
The cost to remodel a basement is between $12,100 and $33,400 for the average homeowner. The price you pay can be as little as $3,500 or as much as $50,200, depending on the size and condition of your basement and the type of remodel you're doing.
If you're doing a simple project like adding a home office to your basement, you can expect to pay anywhere from $500 to $3,000. However, if you're adding a bathroom, which is an extensive project, you can expect to pay between $6,600 to $16,500.
Damp proofing and waterproofing are both methods to help keep your basement dry. Damp proofing keeps soil moisture from entering your basement, which is helpful since your basement is underground. Waterproofing, however, keeps both soil moisture and liquid water out of the basement, which is essential, especially if you live in a wet environment. Because it’s more protective, waterproofing typically costs more than damp proofing.
Although homeowners often use the terms basement remodeling and basement finishing interchangeably, they are quite different terms.
Finishing a basement is the process of taking a basement space that is not habitable and adding elements to make it usable. This includes adding plumbing, flooring, and insulation.
Remodeling a basement means taking an already existing finished basement and changing it, often by adding or removing walls, adding plumbing, or changing the existing flooring.
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.
