"From the first visit to my home from Sean for an estimate, to the crew that arrived to do the project I was impressed. Everyone was extremely professional. The crew arrived on time, the crew leader introduced me to the rest of the crew and explained how they would proceed with the project. They protected the work spaces with plastic from my garage to the crawl space opening in side my closet. They went to work and kept me informed about the progress. The whole crew worked very efficiently and got the project done in one day. They left work area spotless when they were done. I would highly recommend this company for any waterproofing project!!"

"Overall the Crawlspace Crew did some great work for our basement area. The initial phone call was very informative, then they came on-site for a walk-thru and provided an itemized estimate we could understand. We expressed that budget was a concern and only elected to do some of the work, they were supportive of this and we were scheduled in within a week. The work was completed in a timely and thorough manner and we are very satisfied. Shout out to Dillon, for working within our budget, and being flexible on the specifics, I would definitely recommend this company/service to a friend or anyone in need."

"I contacted Foundations First NorthWest and a couple of other contractors when an inspection revealed some foundation settling and crawl space damage. I chose Foundations First to make the repairs because they included more work, and at a lower price, than their competitors. I can't say enough about how professional everyone at Foundations First NorthWest was, from the first meeting with the sales rep to the constant communication with office staff throughout the project. Every step was completed without a hitch -- getting permits, engineering, the repair work and county inspections. The work crews worked quickly and efficiently on both the installation of stabilizing foundation piers, and also on the crawl space repairs. And they left the work areas in a very clean condition. I highly recommend Foundations First!"

"Martin and his crew tore up a paver patio and partial lawn and installed a beautiful patio with pavers and river rock. On time and worked quickly! I was really happy with how I was treated and the quality of work they did. It was a small project which I sometimes have a hard time finding people for and Martin was eager and made me feel like it was worth his time."

"We had an amazing experience with this company. We worked with Byron and he did a fantastic job. Very professional, knowledgeable and they were able to get the job done quickly. We had several quotes about our foundation but Byron was by far the most knowledgeable and we were so happy with the price. We are so happy with his work and will definitely be recommending him! We have reached out to him and he is always happy to help. So glad we chose this company!"

"I had Drainage Masters come out to patch and seal three cracks in our basement and crawlspace foundation that leaked during heavy rain. The crew was on time, super polite, and shockingly efficient. I appreciated their attention to detail as we reviewed the scope of work, and how they ensured I was satisfied and had my questions answered before they left. I also couldn't believe how little dust they left behind; they covered my jam-packed basement in plastic and were very careful when packing up and vacuuming. Great attention to detail throughout! Can't yet confirm whether they officially stopped the leaking, but I feel confident knowing they'll come back to make it right if trouble persists."

"Trenton was wonderful - punctual, and exactly at the time they said they would be here. He was able to pinpoint where the ants were coming from, and sprayed our foundation as well as a number of places inside where they were coming inside our home. We would definitely hire them again - thank you for the great work!"

FAQs for foundation, basement or crawlspace waterproofing / encapsulation projects in Portland, OR

The most affordable way to waterproof your basement is with interior methods like waterproof paint, costing between $1 and $8 per square foot, or silicate concrete sealers priced at $4 to $6 per square foot. However, these solutions are only suitable for certain issues. If your basement moisture is due to more serious problems like a cracked foundation, you'll need more extensive (and costly) repairs.

Absolutely! Waterproofing your basement is a smart investment that can increase your home's value. By keeping your basement dry and free of moisture problems, you protect your home's structural integrity and make it more appealing to potential buyers. Plus, taking proactive measures now can prevent costly water damage repairs down the line.

The time required to waterproof a basement depends on the selected method. Some approaches to interior waterproofing, like paint or sealant, can be completed within a day. Installing new drains or weeping tiles will need at least two to three days of labor. Any forms of exterior waterproofing that require you to excavate land will require an additional three days of work to prepare the ground.

Yes, basement waterproofing can significantly increase your home's value. A dry, leak-free basement is a strong selling point for potential buyers, enhancing your property's desirability and market price. Investing in professional waterproofing not only protects your home's structural integrity but also ensures a healthier living environment by preventing mold and mildew growth.

Waterproofing both the interior and exterior of your basement offers the best protection against moisture. Exterior waterproofing stops water from penetrating your foundation, while interior methods manage any moisture that does enter. If you must choose one, exterior waterproofing is generally more effective, as it prevents water from reaching your home's interior in the first place.
