"Had huge foundation problems at a project of mine on the waterfront. 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."

"4.5 stars overall for removal of concrete slab/stairs and pouring of new 10' long, 4 foot deep foundation wall. Result was excellent. Crew was considerate and trustworthy. It was expensive for me, but cheaper than the other bids I got. Communication was not great over email. There were a number of times I wasn’t replied to at all or got a partial response. I let them know and they said they’ll work on that. I recommend communicating via text instead which worked much better."

"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!"

"During periodic heavy rains we sprung a leak in our basement wall. I called Perma-Dry because both Angie's List and a plumber recommended the company, and I do not know the first thing about waterproofing a home. I scheduled a date and time for a salesperson to inspect the basement and provide me with an estimate. Mark was friendly and professional, and in his estimate he wrote that a sump pump may be required. What he did not elaborate in his inspection is the sump pump requiring GFCI, a term he wrote on the estimate but did not explain during the inspection. I am not an electrician and I have already established I do not know the first thing about waterproofing. What I came to learn during the scheduled work is that a) the crew confirmed a sump pump would be required, and that b) GFCI means a dedicated electrical line for the sump pump. We have a warbox-style home from 1942 and there is only so much we can do to the existing structure. Our washer and dryer are in the basement and now our washer will share an outlet with the sump pump, and I'm going to hope for the best. The work crew is nice but they do love to get animated about the work they are performing. I'm fortunate to work from home today and participate in phone conferences on mute so my colleagues didn't have to hear "BULLSH_T" being exclaimed loudly. Bonus use of the n-word when they returned from lunch. What would have been immensely helpful in the original inspection is Mark explaining, "We should check to see if you have the necessary electrical setup for the sump pump, otherwise you will need to hire an electrician and that could run $600." When I had Mark in our basement I was trying to think of every possible question to ask him before agreeing to an estimate and scheduling a service appointment. Where I failed in my exercise is that I didn't know the questions to ask during the inspection, and now the crew is installing a sump pump that I cannot reject because it's the only way I can achieve the goal of waterproofing the basement. A quick email to the company did not feign a reply from anyone other than a follow-up call with Mark who, professionally, explained he did his part to address his due diligence in the estimate to cover liability for the company. I explained to Mark that since I do not know the first thing about waterproofing (established) I did not know all the right questions to ask, and I am now having to authorize $825 for a sump pump in hopes that I don't need to hire additional servicemen to confirm the work is complete. The conversation was moot aside from him understanding my frustration. If you are a homeowner like me that is unfamiliar with waterproofing and home electrical, be sure to ask the salesperson if your home is properly set up to accept a required sump pump, or if you will need to schedule an electrician to wire your home ahead of the waterproofing work. If you are a homeowner like me that is unfamiliar with waterproofing, make sure you ask your salesperson for visual examples of the sump pump so you can adjust any configuration of storage solutions you had in your basement that must now be reconfigured due to the size of the pump and the space it will occupy. Because you don't know if there is more than one option for the sump pump (there isn't on the day of work). You can, however, hope the crew will not cut into existing pipes and do their best to work with the plumbing. FYI: the warranty offered for the drain system DOES NOT apply connection to an existing non-company installed drain line. Meaning that the sump pump required for completion of work is not covered by the drain system warranty when the crew connect it to your existing plumbing. The crew finished ahead of schedule and I was shown the results. The poured concrete will take 3-4 days to thoroughly dry; we can move our washer back at that time and reinstall all the hoses. I wish I would have known in advance how long it would take for the concrete to be dry but I guess that, too, was a question I was supposed to know to ask. The sump pump is already plugged into the wall socket but we'll need to rely on the battery powering the sump pump control box because we don't have another outlet to spare for the second plug. If we didn't have that outlet at the ready, I would be back on Angie's List looking for an electrician and I wish Mark would have had a checklist at the ready to make sure all of this was addressed before the crew tore open the basement floor with a jackhammer and then concluded a sump pump was necessary. The purpose of Angie's List is to reduce the risk of "Buyer Beware" for consumers, yet here is a business model that penalizes consumers because they don't know the questions to ask. I hope my experience will save you from a similar situation so you're not left frustrated with a company's reply being "I understand" on repeat."

"Upon discovering the source of the leak, Duga Construction provided me with options. I finally chose a new, long-lasting and properly installed membrane as the best overall solution. Duga was great to work with throughout the process!"

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

Yes, crawl space encapsulation is a good investment. It improves your home's energy efficiency and air quality, boosting its value. With routine inspections and maintenance, encapsulation provides a long-lasting solution to moisture and pest issues. Regular check-ups protect your investment, enhance energy efficiency, and maintain your home's structural integrity. If your home is prone to pests or moisture seepage, encapsulating your crawl space is definitely worth it.

A vapor barrier is a thin sheet of plastic that prevents moisture from seeping into your crawl space, while insulation prevents unconditioned air from entering. Combining both insulation and a vapor barrier creates a dry, temperature-stable environment. Some insulation products serve both purposes, enhancing energy efficiency and protecting against moisture and temperature fluctuations.
