    Jake presented a good plan, which avoided problems that certainly would have occurred with the plan presented by your competition. I took careful notice of the reviews on Angie's List, and call some of the references, which were supportive. Finally, I chose Johns as a company that had been in business for some time and had extensive experience installing the basement waterproofing system. The guarantee was an extremely important factor in my decision, and John's track record suggests that it will remain in business and stand by the guarantee should problems occur. This was the best part of the project. Delfino and his crew (Francisco, Aaron, Ceasar) worked incredibly hard, were polite and considerate, and provided what appears to be a good installation. I give them my strongest recommendation. How they managed to hand carry 6 yards of broken concrete up out of that basement in the time they did is beyond me. John's employees spoke highly of the company, and the benefits offered. It sounds like a well run business. Please note that the system was installed in Central Oregon at our second home on the Deschutes River, where we are dealing with a high water table issue in summer. As of this writing, the water table is nearing its summer level, the sump pumps are working, and the basement/crawl space is dry.

    Can't say enough about the installation team. They were neat and on time, met all time estimates and left our home in excellent condition. It was a very satisfying experience. I also providing a rating today on Angie's List that gave an overall score of a B which is still good and fits with my satisfaction and willingness to do business with John's again should the need arise.

    Team reviews: 2. Ramon Morales Thank you so much to Ramon and your crew for their professional work recently completed in our barn. Ramon and his team worked with us as a customer extremely well, in that he reviewed the job before starting, and answered our questions satisfactorily along the way. He worked well with his team, and they were all hardworking and efficient with the time on our job of installing DryTrak and a perforated pipe system around wet spaces in our barn. They left the site very clean. We highly recommend John's Waterproofing Company to anyone needing help with keeping areas dry and healthy. Again, thanks so much. Chuck and Linda

    The room where our crawlspace access is was cleaner than before they started. Very impressed with how thoroughly they cleaned the crawlspace out, especially with the old sagging insulation.

Exterior Excavation

Heavy equipment is brought in to dig out the entire perimeter of the basement. New drain lines are installed, and sometimes a waterproof coating is applied to foundation walls. This waterproofing strategy is expensive and often damages lawn and garden areas. Exterior drains are prone to clogging with silt and roots over time.

Interior Subfloor Drain

This drain line is installed underneath the basement floor, just inside the foundation walls. The hidden drainage system brings water to a sump pit, where a sump pump automatically pumps it outside. Also known as a French Drain, this system is not prone to clogging; it’s reliable and easy to service.

Interior Baseboard System

A hollow plastic baseboard is installed along the base of basement walls to form a drainage channel that directs water to a sump pump system. A baseboard-type drainage system is sometimes recommended when the basement slab is too thin to accommodate a French Drain.

Negative-side Sealant

This waterproofing technique involves "painting" basement walls and floors with a waterproof, cement-based coating that's supposed to seal out moisture. Even when applied correctly, this thin membrane usually fails in response to prolonged hydrostatic pressure from outside the foundation.
