"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!!"

"your team was very impressive. We had other people out there inspecting the crawlspace, but no one except for The Crawlspace Crew had the guts to crawl the whole thing in the not so pretty parts of the crawlspace, and because of that we noticed that he had a broken pipe and leak. You were very impressive with your services, I wish you did plumbing too! I believe one of your guys is a home inspector (Travis I think?), and he was really thorough and good and he is on the maintenance board for the HOA and he wants to recommend to every one of their homeowners that we inspect their crawlspace."

"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!"

"I bought their contractor for a day at $300.00 which seemed like a deal. The thought was an online video indicated that the project could be done in one day by an inexperienced person. I met with the owner and we agreed that maybe it would take two of his experienced experts An entire day (so $600). We had challenges right in the beginning. There was an electricity outage in the neighborhood that slowed work as they could not use their saws or drills, then the two guys spent a long time arguing about how to do it, then the first four hours were up and one guy left and the other guy diligently stuck around to make up for the time wasted arguing and manually sawing which I appreciated(just to back up a second I had called the owner in the morning to discuss the outage and rescheduling and we had agreed that it would be okay as the equipment had batteries). The manager and I worked out a deal to bring out the one guy for an extra day at the same rate to finish it up and I want to say that I ended up adding one more day but this was two years ago. Nice hard working guy, just slower and less efficient than others I had worked with (in his defense he cost half as much). In the end my under deck roof is okay...it has a lot of spots that leak so my level of satisfaction is not high. In the end I got the work done at $600 (or was it $900?) This was a while back. It took two days I think, maybe three. At the end of the day I paid a C price for C quality work. In retrospect I could have recruited my brother to help me do it but it would have taken us four times as long and I can’t say the quality would have been better. Honestly if I had bid the whole job itself another crew might have charged me $3,000+. So with labor and materials I paid $1,200 maybe $1,500 and it’s adequate. I did appreciate the managers flexibility in extending the special price over additional days and letting the one guy stick around to make up for the bickering and electrical outage."

"Ethereal Elements provided exceptional, professional and quality work repairing my basement wall leak. Dealing with Q was very easy, he is personable and to the point. Dale, who performed the work knew exactly what he was doing, he was quality oriented from start to finish. The work was completed on 4 October, I held off writing this feedback in hopes we would have a couple of extreme downpours so I could verify the basement would not leak. Q guaranteed the basement would not leak again, or they would come out and fix it. The cost of this job was reasonable and I was able to use the discount coupon. I would hire Ethereal Elements again."

"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."

FAQs for foundation, basement or crawlspace waterproofing / encapsulation projects in Sandy, 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.
