Heartfelt thanks to Lior and his crew for their outstanding work. Finishing the entire project in only two days was nothing short of a testament to genuine American efficiency. Our primary reason for choosing Northwest Crawl Space Services was their ability to provide a comprehensive, one‑stop crawl space solution. They offer the full spectrum of crawl space restoration services and can also install a sump pump system. We also used their high‑quality rodent prevention services as part of the project. Among the companies AI recommended to me, Northwest Crawl Space Services stood out with exceptionally strong customer reviews. I also browsed through some customer reviews, including a long, thoughtful one written by an older gentleman. He wrote, "Lior was our lead person for questions and he made it easy to understand, going over everything--I mean everything!" Lior is also the blogger who wrote the educational articles and the detailed, highly informative work logs on the company's website. And as luck would have it, the company assigned Lior to do our estimate. Now we can say the same thing: everything became easier because Lior stepped in with such calm, steadiness, and responsibility. On the day of the estimate, Lior told us they would protect the laundry room and the garage, and that they would do their best to complete the project to a high standard--he even said they would make our crawl space "beautiful." Our only expectation for the crawl space was basic functionality. It is technically part of the house, but the last time I went inside was thirteen years ago. This time, however, when I entered the crawl space to take photos, I had to admit that their attention to detail was truly impressive. I'm posting a few photos here--this is only a small portion of what they accomplished. The quality of the work far exceeded anything we had imagined. Considering the hours they spent in that low, dark, cold, and damp environment only deepened our respect for their perseverance. During those two days, even though the work was physically demanding, we could still feel that they were genuinely happy. This speaks both to their inherently positive mindset and to the healthy, supportive workplace culture within the company. The office staff were equally enthusiastic and provided the same high level of friendly, professional service. NWCSS is a company you can truly trust. A few days later, on a sunny afternoon, I went back into the crawl space. What I saw made me finally understand what "beautiful" truly meant. I sat there quietly, watching the interplay of light and shadow between the new floor insulation and the new vapor barriers, with the new air ducts weaving through the space in graceful lines. In that moment, the present felt eternal. Lior delivered on everything he said he would do. Highly recommend! read more

I've lived in my home for almost 6 years now. Before I bought it, the inspector found evidence water had been in the crawl space, so the cost of remediating the crawl space was deducted from the purchase price. After I moved in, I had 3 different crawl space remediators provide estimates to install a sump pump, replace the vapor barrier, seal air leaks, insulate and seal air ducts etc etc. However, not ONE of them knew (or cared) where the water was coming into the crawl space FROM. They'd "fix it all w/a sump pump, seal it up and no more problems!" That never made sense to me. I wanted to know WHERE the water was coming from before sealing everything up.... 6 years later, the yard drainage has been permanently fixed. I was the one to figure out where the water was coming in from after countless times in the crawl space, and an embarrassing amount of time spent in the yard inspecting downspouts, downspout drains, puddles on the foundation, pools in the yard and so on. Now that the water situation was corrected, I wanted to get my crawl space remediated. Seven contractors later, a very smart and picky neighbor of mine referred me to NW Crawl Space Services. WHAT A BREATH OF FRESH AIR THIS contractor is! Because I'd done extensive research on my own over the years, I knew what I had and didn't have in the crawl space. Matan came out as scheduled, we walked the yard to look at my drainage system first. THEN he went into he crawl space and formulated a plan to remediate it. He told me many things I did NOT need (which I somewhat knew) and the things I DID need. THIS contractor is actually honest! For the first time a crawl space contractor whose plan made SENSE! Needless to say, I eagerly scheduled the work. The crew came out as scheduled, were polite and worked hard all day. After they left, I admit, I went into the crawl space to inspect myself. I was 1000% impressed. A week later the other co-owner, Lior came to inspect the work his crew did in my crawl space. Everyone's delighted! After all these years having that crawl space mitigated, AND having a contractor I can trust what they tell me, AND it makes sense, AND they have a maintenance program that THEY go into the crawl space periodically to make sure all is in order?? I cannot TELL YOU how delighted I am w/their work, efficiency, expertise, professionalism, service, knowledge base, and responsiveness. If you need an HONEST opinion of your crawl space, call NW Crawl Space Services and save yourself a LOT of time and headache. AND Matan and Lior are BEYOND delightful and KNOW their work. No salespeople, you're dealing with the OWNERS of the company. I'd give them 100 stars if I could. Forever grateful! read more

This winter, we noticed some leaking in our crawl space due to an old cast iron main and aging galvanized steel drain pipes. Turns out, Northwest Crawl Space is also a licensed and bonded Plumbing outfit! In addition to the plumbing work, we needed to handle some ground water issues in our crawl space. They came in with a quote to do both projects that we couldn't refuse. Here's our experience: - EXCELLENT COMMUNICATION - When estimating the plumbing work, Travis, came into the crawl space with me to show me exactly what he planned to do. The quote was incredibly detailed and broken out into easy to read line items. Matan, the co-owner of Northwest Crawl Space, kept consistent communication with daily visits and text/calls between days throughout the entire process with great care and professionalism. - FANTASTIC QUALITY - The French drain/sump pump was installed within a day using high quality lava rock and durable drain pipe. They used a highly rated Ridgid sump pump, a backflow stopper, and a shutoff valve, which results in an excellent build for the long term. - CUSTOMER-CENTRIC - The job took several days, and at the end of each day, Travis left all the drains usable, which meant we could use the toilet, sinks, and washing machine between days. That takes excellent planning, foresight, and plumbing expertise; this greatly reduced disruption during the project. - SKILLED INSTALLATION - The joinery and routing is the cleanest I've seen; exceptional craftsmanship. Not only was a standard two-way clean out installed outside, but the existing clean out in the crawl space was relocated to a more convenient position for easy access in the long-term. I would, without hesitation, recommend Northwest Crawl Space for any of your crawl space and plumbing needs. Their ability to plan and execute these two major projects for us is unparalleled. The crawl space work improved the quality of indoor air and reduces the chance of issues down the line. With the plumbing complete, we have stopped worrying about waste water from dripping into the crawl space. At the very least, give Northwest Crawl Space a call and see what they could do to improve your home; they are exceptional! read more

I had a leak coming through my closet ceiling, and went through a long process of trying to get different people to come out and assess where the problem was originating, since I'm not physically able to get up there and check it out myself. Northwest Crawlspace was willing to come down to Lacey to check it out and give me an estimate, at a specific time and date, which started them off ahead of almost everyone else I called. The owner, Lior, came out himself. He got up in the attic, showed me pictures and video of the problem(s), and gave me a competitive estimate, with a discount to send his crew out the next day. Incentive to start right away? Sounds good to me. The crew arrived on time, and none of them spoke good English, so they used the translator app on their phones to communicate with me throughout the day, and it worked great. They had no problem telling me exactly what they were doing, friendly and having a laugh here and there. I had prepped the master bedroom a little bit, covering things up - I didn't need to do any of that! Lior's crew put up plastic barriers over everything, including taping a barrier wall from floor to ceiling to completely isolate the half of the room where they were not working. Floors were covered all the way to the front door. And they notified me before starting up the fog. I have no complaints about this crew! Savannah in the office was friendly and always reached out at the right times. To top it off, the owner voluntarily returned a few weeks after work was completed, free of charge, to inspect it again taking photos and videos of the work and making sure you're satisfied. That's just a thing he does. I think you have to give credit to a guy like that. He was honest, and he's got a great sense of humor. (I had one cheaper "estimate," but that guy wouldn't even come out and look at the problem, so I had no faith in it.) I'm happy to pay fairly for quality work, and that's what I got here. Definitely recommend. read more

After a big rainfall, my home's crawl space had significant amount of standing water, which I was able to mitigate with several pumps. However, this was a band-aid fix and knew I needed a real fix. I contacted several companies in the area and went with Northwest crawl space services after a few assessments. My house is in a flood area and it needed the sump-pump to be up to code with its connections, trenches dug under perimeter of house to have avenue for water to reach pump, and a way for water to leave property (to drainage ditch). The owner Matan gave a thorough assessment and quote that I found to be competitive (a good deal) with other highly rated companies; I also found Matan to be very transparent, honest, and someone I wanted to give my business to. Also, I saw all 5 star reviews on Google so felt confident in my choice. The crew worked really hard all week, and did a great job. Matan communicated often with progress and always made sure to ask if I wanted to assess / understand anything that was going on step by step. Overall, I felt that the work was professional and high quality, and also like the job was personally cared for. The team worked late on some days which is great (it got the job done); however, if you adamantly don't want any late days on your property/is important that clean-up occurs immediately (ie not potentially day after - this was asked in progress), I would advise communicating this expectation prior. I did not care, so give 5 stars, but do realize this might not be appreciated by some folks, so just giving heads up. Overall, Matan and his company were fantastic and I highly recommend. I am actually contacting them for another job in attic insulation. read more

We had 3 companies come out to inspect our attic. Niko from Northwest Crawl Space came out to inspect our attic and alerted us to mold and mildew, dirty and old insulation which was lacking, and a detached duct. Aside from having the best name on the planet, Niko was kind, professional, and very knowledgeable. We made our decision to trust Niko and Northwest Crawl Space. Tristan and crew came out to take care of our attic. They were professional, kind, and worked hard all day long. They had the attic completed at the end of the day. They were super clean and careful and had all the debris removed from start to finish. My husband John checked out the attic afterwards and said everything looked great. Niko as well came out the next week to inspect the work that had been done. You can tell a huge difference by the pictures that were taken for the before and after process by Niko and Tristan. The insulation in the attic before was lacking, after Northwest Crawl Space completed our attic you can definitely see and tell the difference. Old insulation was taken out, new insulation added in, air leaks were sealed, any entry points were sealed for prevention of infestations, mold and mildew were treated, sanitized, baffles installed for proper air flow, and a duct that was disconnected to a damper vent was reattached. From start to finish we are extremely happy with the work done by Northwest Crawl Space. Communication/customer service was perfect, Niko, Tristan and the team are seriously the best. We highly recommend Northwest Crawl Space hands down. We will be using them next month for our crawlspace. Thank you Niko and Northwest Crawl Space, we appreciate your honest and hard work. -Sandy Akins read more

Recently I needed a complete crawl space overhaul which also included a new sump pump install. I wasn't sure who to contact so went online and did some research and found Northwest Crawl Space Services. In addition to NW Crawl Space, I also got two other quotes to keep everyone honest. After all, three companies did their inspections and submitted their quotes I chose NW Crawl Space. The choice was based on the great reviews I read, and their price was also the least costly for all the work I needed. The work needed was a complete removal of all the old insulation and old ground cover and sealing of all ductwork, it turns out that there was a problem with rats and mice infestation, so they sealed all access points for the pests, and then installed new R30 insulation for the floor and R11 for all the ductwork. I had also noticed that there was standing water in the crawl space over the winter, so they also dug a trench around the inside edge of the crawl space and then ran it off to the low corner and installed a new sump pump well and sump pump and ran the pipe out to a dry well rock pit in the yard. What a difference it has made under the house. I used to dread going under there to do anything. Now it is so clean, and I am sure that my wife and I will be much warmer in the winter and cooler in the summer because of new insulation and sealed ducts. As for the work quality, I couldn't be happier. The workers were professional, they worked fast and any concerns I had were rectified immediately. I highly recommend that if you need crawl space work you contact Northwest crawl space services. You won't be sorry. read more

Northwest Crawl Space Service is the best. We called them because of terrible smells coming from our vents and even through the floor because of dead rats. We would just get one dead rodent removed only to have another in a month or so. We knew they were doing damage and causing an unhealthy situation for us. Leo and his crew just finished up doing a wonderful job in our crawl space as well as the air ducts, both intake (in the ceiling) and under the house. They found one vent broken and replaced it at no extra charge. They also decided to replace one of the ducts rather than the agreed-upon repair, also at no extra charge. We also got a 5-year warranty, which includes 3 visits over the next year and 1 visit next week to check the traps they left for rodents. His guarantee covers the "exclusion" part of the job, which means they seal up all entry points and then come back to make sure no rodents are getting in. If you get other estimates, be sure to ask about an exclusion guarantee. No point in going to all this work and expense only to have rodents get back in and wreck everything. I was happy with the knowledge that they cleaned, sanitized, and deodorized both the crawl space and the air ducts. Leo and his crew were very courteous, explained what they were doing throughout the day, and showed us photos of everything after they finished. Part of our contract was a hug at the end of the job, which I got, although my husband only got a handshake ;-) . We will not hesitate to call Leo and his crew back when it is time to have our air ducts cleaned again. We recommend him without reservation. read more

This is LONG overdue - in 2/23 Northwest Crawl Space (NWC) gave me a quote for repairing water exposure in my crawl space which included removing and replacing all the insulation and floor barrier and mold treatment. My insurance agent wanted to use a different company which charged them twice as much as NWC for just the dry out, insulation, and mold remediation and they did a horrible job - I went down to check the work and saw that they didn't remove all the old wet insulation and were just going to leave it in a back corner. Even after calling them out on it there was still some insulation they didn't removed until I pointed it out...again. Furthermore, the company my insurer selected (NOT NWC) was terrible to work, were unprofessional, and were disrespectful of my time (would show up without any notice). Then NWC came out and put in a new floor barrier AND as a courtesy repeated the mold treatment (for free) because the other company did such a poor job. They followed up with a scheduled visit to make sure all was well a few weeks later (who does that?!) and did not try to upsell me as everything was looking great. Today, I had some concerns about my crawl space arising from the work the other company did and Matan from NWC came out and told me all was well - no high sales pressure, just an honest assessment and helpful suggestions. Wow - I wish there were more companies out there like Northwest Crawl Space! read more

We worked with Mark Getker from Crawl Space Services in Kent, WA.. Double excellent from start to finish - and we had a lot to do. Vapor barrier was old and destroyed with holes , water in the crawl space, rats in the crawl space, rat nests in the crawl space insulation, rat burrows in the crawl space, mold on the attic ceiling , and mold in the insulation on the attic roof, ventilation pipes from bathrooms not connected directly to the outside. New and better (10mm thick) water vapor installed, all insulation removed and replaced, sump pump installed, burrows filled with hard materials, mold professionally treated, ventilation pipes connected and new breather vents added to attic. We talked to about 7 contractors - Crawl Space the only one we talked to that did all the thin gs we needed done.. Total price was about the same as the others (if we hired several of them) but Mark did the job better. For example, the min thickness of vapor barrier is 6 mL. All other contractors gave quotes with barrier thickness go 6 to 8 mL. Crawl Space original quote was for 10 mL. All other quotes were for putting barrier on floor only - Crawl Space took it up the sides 2 to 3 feet. They saw the need to add additional breather vents to the attic. All workers were friendly, polite, clean and courteous. We made the right decision when we chose Mark and Crawl Space read more

My house needed some attention in the basement crawl space because of rodent intrusion. After some online research and some unsatisfactory experience with a prior well-known company, I finally called upon Northwest Crawl Space. Savanah was so helpful and patient with all of my questions. We scheduled an inspection and Matan provided me a scope of work and estimate right up front. What I appreciated was his straight forward approach to fixing all of the problems and not being a hard sell on services. I was able to pick and choose what my priorities were based on my budget. He also has a great, hard working team on board! I was so impressed with the amount of care and attention to detail that they provided. None of the tasks they did were easy or fun and yet they got in there and tackled each one with tenacity. What I appreciated most was when they reached out to schedule the follow up inspection. Together, we looked over the work and he made sure that all was done to our agreed upon understanding. I would highly recommend Northwest Crawl Space! read more

Our house was built 1933, found beetle damage under the house. Lior, Co-Owner crawled under to assess damage & provided a "detailed" quote, which we got before he left the yard. We interviewed 3 other companies. No question, NW Crawl Space, hands down. They have the crew & expertise for the job. When you're given a time, take that to the bank, here 8:00am sharp, love it! 2 weeks later Rob & his crew came out. By the end of the day all insulation/debris removed, bagged up, trenches dug, sump pump installed, sprayed for rodents. One day back, insullation up, new doors built, secured vapor barrior. These guys are PROS, great team dynamic. The positive energy they bring to the job site, rocked it for us. Lior came back today for his final inspection. Love doing business w/ him, mostly because he values his team & their expertise, he's honest & cares for his clients. Thank you Northwest Crawl Space from Olympia read more

Our 30 year old home needed crawlspace remediation to get rid of rat tunnels in the dirt and poop, torn insulation, easy to pass through vents, and lack of security from critters outside. Northwest CrawlSpace Services was wonderful to deal with from start to finish. They returned every call, explained in detail what we needed to prevent rats or other creatures from getting into our crawlspace, took before and after photos so we could see what we needed and later what they had done, and they even helped us get a rebate from PSE for upgrading our crawlspace insulation. Every person we dealt with was professional, thorough, polite, and a pleasure to deal with. The work crew was on time, neat, and hard working. NW CrawlSpaceServices even offers a 10 year plan for crawlspace protection going forward which we plan to use. We can't recommend them highly enough. A++ read more

Estimate was precise, detailed all work to be done. All my questions were promptly answered. Project for restoration of crawl space of manufactured home entailed removing old contaminated insulation and belly paper and then the vapor barrier. New insulation, spray to protect pipes and air ducts, new vapor barrier with taped seems, etc. crawl space is now clean and buttoned up for winter. After the project was complete I noticed my air conditioning wasn't working. Apparently a breaker had gotten flipped and I didn't realize it. I called Northwest crawlspace services and they sent a HVAC person out right away and the issue was promptly resolved. Couldn't be happier with their service and putting the customer first highly recommend this company. read more

After having no water issues for 20 years, we came home from vacation last year to find almost two feet of water in our crawl space. The water had soaked the insulation on most of the air ducting, causing them to pull free from the registers and had damaged the foundation footings. Northwest Crawl Space Services was the only company we contacted who could take care of our issues quickly. Robert's crew put in drainage and sump pumps, replaced all of the ducting, and replaced 65 footings and structural support beams. All of the work was done quickly and efficiently, and everyone associated with Northwest Crawl Space Services was extremely professional and helpful. I highly recommend this company for any crawl space work. read more

Our crawlspace was completely torn up by a possum that was living down there. Some of our heating ducks were not hooked up so we were getting cold air into the house. The possum had destroyed the heating duck and also had destroyed the insulation underneath our subfloor. Northwest crawlspace came out and did a thorough inspection and presented us the information through pictures. Within the week we had hired them and they spent two days fixing our crawlspace. From the estimator to the crew, everything was very professionally done. All materials were taken away and the surroundings cleaned up. They also put in a sump pump to take care of water underneath the main part of the house. read more

We knew we were in need of a crawl space / rodent inspection. Saw an ad in our Sunday paper so decided to give this Company a call. Very prompt- showed up on time AND wearing a mask- very nice to see in COVID times! He quickly crawled under our house, took videos and explained what needed to be done. First he set traps to ensure no critters were living there and followed up later- communication is so great with this company. The crew arrived promptly and removed the old insulation (they hauled it all away), sanitized and replaced with new insulation and a vapor barrier! Looks awesome- they worked well together and finished quickly! We would highly recommend this company! read more

My 1920s-era house has a crawl space that rats love. Over the years I evicted them repeatedly and cleaned up afterwards. Repeatedly, they returned by burrowing under my shallow foundation. Finally, I realized that I would never be able to keep them out without a "rat slab," that is, a layer of concrete covering all of the dirt in the crawl. Northwest Crawl did a great job of designing and installing this slab. They know what they are doing. Their employees work hard and fast. They are polite, professional, and guarantee their work. To my delight, I now have a clean and rodent-proof crawl space. I highly recommend Northwest Crawl Space Services. read more
