Job Stories From Harmony, PA
Mold in Harmony

This homeowner had called upon Keystone Basement Systems after finding them online and seeing that they could help with the mold growing in their basement. Keystone sent out one of their field inspectors to meet with the family and go over the issue before conducting his very detailed inspection. The field inspector knew right away that it was black mold that this family was facing and so he had to come up with the best plan that not only kill what was there but also prevent new mold from growing back. The plan consisted of installing a drainage system along with a Sedona dehumidifier and some CleanSpace, with anti-microbial protection called UltraFresh built right in, no mold or mildew will grow on the CleanSpace! If you have stone walls, an exposed ledge in your basement, or dirt floors, CleanSpace® is the perfect solution! With its 25-year warranty from rips or tears, you can be sure it's strong enough to do the job!

Crawlspace encapsulation in Harmony

This homeowner called upon Keystone Basement Systems to encapsulate the crawlspace of his uncle's home, which they were getting ready to sell. Keystone sent out one of e their finest field inspectors to meet with this homeowner and go over the plan that he wanted to be executed at his uncle's home. This homeowner was a very pleased previous customer that knew what he wanted. The field inspector then performed his inspection and came up with the exact drawing/plan to get this project done. The project consisted of a total encapsulation of the crawlspace.  The homeowner was very happy with the results of this encapsulation and went on to call upon Keystone again for another project that he had!  

Waterproofing in Harmony

This homeowner had called upon Keystone Basement Systems for help with their wet basement. Keystone knew that they had to promptly send someone out to them as this family sounded very concerned with the condition of their basement. Field inspector Chris was scheduled for the very next day to help this family. Upon arrival at his appointment, the field inspector noticed that the downspouts had nowhere to go and water was just billowing out over the top and running down a basement wall.  The field inspector noted that and then moved on to sitting down with the homeowners to go over the issue at hand, once he had gone over the questions and concerns the family had he then quickly go to work performing his very detailed inspection of the problematic area. The field inspector was sure he had come up with a plan to get this house dry again so he then re-approached the homeowner to go over that and any questions that they might have about it. The plan consisted of installing an internal drainage system as well as CleanSpace and definitely the new downspouts. This plan made the homeowners feel more at ease and they too were sure it was going to work. The field inspector then returned to the office and got it on the schedule for installation. The foreman and his crew then quickly got this job underway and completed it with great expertise and care. The home is now dry once again and the family is very happy that they can return to using their basement again.
