"I had a challenging project to remove and then install new irrigation piping and control valves around my property. They brought in the right size crew for the job, and were able to complete this work in just one day. Rain Pros teams were knowledgeable about every aspect of the job, giving me several possible solutions and making a good final recommendation so that the job would be done correctly and within stated cost estimate. I would certainly recommend them for any irrigation system repair, modification or new installation."

We used terrafirma to both waterproof the entire basement AND lift the foundation. 10/10 would recommend. extremely communicative, very knowledgeable, and even brought a crew in from Oregon to help us stay on schedule. Oscar and jorge got the job done extremely quickly and Seth was fantastic as my project manager. "

"Outstanding work and value. Andy was quick to respond and came out the next day to assess what we needed to do to improve the drainage in our crawlspace. The home is built on a sloped lot. Andy suggested a full perimeter drain install around the foundation. The work also included complete replacement of the vapor barrier. All work was performed efficiently and Andy backed it up with a lifetime warranty. I couldn't be happier with the end result and would highly recommend Andy and his crew."

"Excellent company! These guys did a great job of installing insulation in my attic as well as the removal of old insulation. Also, the clean-up job after the job was great too. The technicians were knowledgeable and friendly. No issue in recommending."

"The workers were on time. Very efficient. They did a blower door test and found the air leaks and insulated these areas. Blew installation above the garage, cleaned out the crawl space and put new installation there and basement. Found a water leak from my toilet,Thank goodness. Covered everything in the basement and swept and cleaned up after. I would recommend them!"

"<p>We read about this company on Angie's list and decided to give them a try.  Gave them a call and Marcel came out in just a few days for an inspection and estimate.</p> <p>Based on everything Marcel said, we decided to go ahead and have them do the work.</p> <p>I'd been seeing occasional rat poop around the small entrance to our attic, whenever the door was disturbed, so I knew something was going on.  They got up there and there was LOTS of rat poop, but luckily for us, no rats currently in residence!</p> <p>Marcel explained their process and what else he'd seen up there, including a vent pipe from our kitchen stove that hadn't been properly connected to the outside.</p> <p>In addition to removing all of the old insulation (essentially with a giant vacuum cleaner!), they sanitized the area, patched or repaired any access points, fixed the unconnected kitchen vent, added some additional soffit vents, rescreened any other vents and then blew in high quality insulation.</p> <p>So now, on top of feeling secure in having a rat free and clean attic, we should be seeing a reduction in our heating bills as well, from the better quality insulation they put in.  NICE!</p> <p>I want to commend Marcel, in particular.  He was very knowledgeable and easy to talk to and understand.  And because we've done a lot of work on our house lately, with a few unfortunate situations, we really peppered him with questions and he was very, very patient with us, which we really appreciated.</p> <p>The guys who did the actual work--boy, they worked hard!  They did it all in one full day.  Only took a week or two to get the appointment, too.  </p> <p>And they literally built a tunnel of plastic sheeting from our front door to the attic entrance, so there was no worry about dirt or dust or any of the soiled insulation getting in the rest of the house. </p> <p>All in all definitely one of our best experiences with hiring for work on our house.  </p> <br />"

"They were incredibly responsive during a very hard time. In the space of 4 days our home flooded (during a week when there were lots of homes flooding -- they had a foreman on site to take a look within 24 hours, when a competitor wouldn't have been able to even look at the problem for a month). In addition to our home flooding, our son was in a terrible accident and was in ICU for several days, and the hospital for 5+ weeks (he's still there as I write this). Some folks from our church called Justin at Western and asked if they could provide the labor and they could install the sump system to take care of the immediate flooding project. My wife and I weren't even there and between our awesome Church family and western they dug the trenches and installed a sump system to take care of the flooding issue. Western was super busy with the unprecedented flooding, but they worked with us. The second part of the project in preparing the foundation in a stairway to the basement hasn't been completed yet, but is scheduled, and I'm confident they'll do a great job with that too. I'll repost more info if I feel it is needed."

"I had renters in house in front of me who threw garbage off their deck, had large dogs...never cleaned up messes, garbage and junk littered the yard, etc.  <br /> I started having rat problems and when the pest control rep. came out and went under the house and attic, he said I  needed to have both areas cleaned out because of all the rodent feces, etc. there. I had one estimate done but wanted another one so I <br /> checked Angie's list for companys that cleaned out crawl spaces and attics.  I read all the ratings and comments of people having hired these companies and chose Miguel's company, STANDARD INSULATION AND REMOVAL , INC. because of the comments made by people who had hired him. <br /> I called him right away and he came out early the next morning and gave me 2 estimates...one for the crawl space and one for the attic as I requested.  (I showed him  the first estimate and asked for an estimate for the same work)  I blanked out the name of the first company.  He gave me the estimates and explained that he used products that were as good or better and explained the procedure for removal and installation.  He answered any and all questions I had...I tend to ask lots of questions.  (His estimate was about $2000 cheaper than the first estimate) <br /> Miguel and his co-worker were out every morniing by 8am and worked all day until about 5pm.  They worked  long and hard in miserable cold, wet weather.  <br /> I can't say enough about the work ethic and professionalism of Miguel and will recommend his company to anyone who asks for a recommendation.  <br /> My house was built in 1979 so the insulation rating was only R-15.  The drastic increase in the insulation should make a big difference this summer...if and when it gets hot... and of course the heat bill should show some difference too."

FAQs for foundation, basement or crawlspace waterproofing / encapsulation projects in Dupont, WA

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.
