Before and After Pictures from Portland
Musty crawlspace in Portland Oregon

Musty crawlspace in Portland Oregon

This crawlspace was dirty, musty and full of stagnant wet air. Our team came in and removed the debris from the crawlspace, provided appropriate drainage and completed the system with our patented SaniDry dehumidifier. Now the air in the home is cleaner and healthier and the crawlspace is safe from mold and rot. Next week this crawlspace will receive spray foam insulation to better regulate the homes temperatures and increase energy efficiency throughout the home.

The dirt under the crawlspace in this home was so moist that it was a step away from being mud. Our crews went in and sealed up the crawlspace which protected the home from the moist dirt and prevented destruction to the home above.

This very large space created cold drafts into the house and cold wood floors throughout the year. Our crew removed the old torn black plastic from the floor and encapsulated the space. 

Homeowner says, 

“A very positive experience! Everyone I dealt with was friendly, knowledgeable, and easy to work with. The contractors were punctual, work was completed professionally, and they cleaned up after themselves. What used to be a wet and musty crawl space is now a dry, clean space after their careful work and installation of a sump pump. They also offered a discount for paying on completion!  John's Waterproofing comes highly recommended by this customer; I have already referred them to friends!”

Job Stories From Portland, OR
The tunnel in Portland OR Raleigh st

This job was unique. This home had a basement with an attached tunnel that led to a tool shed. Upon entering the tunnel you were able to see areas where the water came in through tiny cracks along the wall and top of the tunnel. The basement was more of the same, as well as the garage. Considering the house was in preparation for sale, the owners new the problem had to be addressed.

Our company came in and installed our Waterguard system, Drain mat, and a French drain system to address any water that may seep into the home. We also installed Thermadry Flooring and an Egress Rockwell to add a finished beauty to the system.

The homeowners wrote us this lovely letter to talk about their experience with John's Waterproofing Company:

"We are writing to express how completely satisfied we are with all the John's Waterproofing folks who have guided us through the process of finding a solution to our basement woes. It was only months ago that we could be found washing and drying towels after sopping up water from the basement bedroom and garage floors. Since the new waterproofing system has been completed, we have endured several stretches of rainy days without any problems. We couldn't be happier!

Your staff has been especially helpful in so many ways. Jacob Bilyeu deserves a special thanks for conceiving the system that would capture any water seeping through the walls and floors of our basement bedroom, the tunnel leading down to our garage and the garage itself. I have happily explained to family & friends how the network of Thermal Dry, Water Guard & Drain Mat in the basement bedroom collects water that may seep into the bedroom conveying it to the French drain & Drain mat under the tunnel floor, down to join water that collects in the Water Guard on the perimeter of our garage, and out to the gutter. Your technicians have been most helpful in showing me how to flush the system from two access locations; information I will pass on to the new owner of the house. Of course Egress Rockwell adds beauty to the egress window installed by Lifetime Windows.

We also wish to express great appreciation for the flexibility of scheduling that John's showed which allowed us to arrange for All-American Concrete, Lifetime Windows and our carpenter who did the framing in the basement bedroom to fit us into their busy schedules in order for us to get our house on the market in a timely fashion. Allowing our multiple contractors to have access to a John's Waterproofing representative while doing their part of the project was a critical step in interfacing all efforts. For her efforts and cooperation we must especially thank Marisol for helping to make it all happen!

The men who labored hard to prepare our house and install your technology deserve credit as well. Manuel and his crew did great work and took the time to explain how the system would work once completed.

After searching the internet for methods of trying to achieve a dry basement we settled on John's philosophy of directing water that manages to find its way into a house. We will make an effort to share that information with other homeowners who seek the same solution as we did. A good start will be our positive report to Angie's List. Thanks to you and all of your staff for what appears to have been a very successful job! Let it rain."

This house now has a beautiful basement room, capable of withstanding the elements and an amazing warranty to go with it. What was once a problem area is now a unique and beautiful feature of the home.

Finishing a basement in Portland Oregon

Shawn had a wet basement in his otherwise fabulous Portland home. Our team came in and installed a partial Waterguard system. While this took care of the water coming into the basement, it was not a full solution. During one of our proactive service appointments Shawn complained he still had some damp areas in his basement and odor issues. Our service technician recommended finishing the Waterguard system, and installing a Sanidry dehumidifier to reduce the moisture in the basement.  Shawn could  finally finish his basement remodeling and add more living space to his beautiful Portland home. We also gave him information about Total Basement finishing and our line of products designed specifically for basement environments.
