We recently hired Northwest Crawl Space Services to perform a complete remediation of our crawl space which had a rodent infestation. Lior initially came out and did a thorough assessment and explanation of what work needed to be done. He was very detailed in explaining all work that they would do and the subsequent follow up visits and warranty that was included in the price. The following week Robert and his crew came out to perform the work. They were punctual, courteous and extremely professional in every way. They took caution and care to make sure that the inside of our house was properly masked off and protected as they removed the entirety of the contaminated crawl space insulation etc. Robert provided me with detailed pictures of the finished work and as well as pictures of a couple water pipes that had very small leaks, which I greatly appreciated. As promised, Lior came back out two weeks later to inspect all work and make sure that there were no problems. I highly recommend Northwest Crawl Space Services!

Lior and his team were fantastic. They were cheaper than the big name companies and didn't try to upsell me to repairs that didn't need to be done. They took care of the problem quickly and were great with communication and photos of the project as it was being completed. They owner even did a follow up the next day to make sure the job was done correctly. I had a list of questions when the job was done and he already had them all addressed with pictures and videos of everything. They are locally owned and operated which is very important to me. Would highly recommend

NW Crawlspace is an exceptional company. Matan and his team are experts at repairing Crawlspaces and protecting you from rodent and water Intrusion.. Rob and Leonardo and the team take the quality of their work personally. They are going to do it right and come back to check it for you. We needed a total clean out and sump pump system installed.They worked super hard to have it done by Thanksgiving. We feel like we got a bargain after seeing all that was done. I recommend them if you want your crawlspace worked on or inspected. You will be glad you called them.

We had a sump pump fail and ended up with a crawlspace that had at least two feet of standing water. Matan of Northwest Crawlspace Services came out to inspect. After examination, he carefully explained our problem and his proposed solution using easy-to-understand, non-technical language, and then gave us a firm price quote. His professionalism made us feel very much at ease and gave us assurance that we were in good hands. The very next day, a worker was sent to pump the water out of the crawlspace so that work could begin. After the water was gone, a crew of three workers was dispatched to begin the work. Before doing anything, they took great care to install plastic sheeting to protect all of the walls and floors leading up to the crawl space access door. The crew worked diligently throughout the day and completed most of the work. Afterwards, they thoroughly cleaned up, leaving little sign that they had even been there. The following day, they came back to finish the work and replace some duct work that had been damaged by the flooding. A little later, a separate person (presumably a supervisor) came by to inspect the job. We are thoroughly satisfied by the work of Northwest Crawlspace Services and would highly recommend them to other homeowners.

Frequently asked questions

What causes cracks in foundation footings?

Cracks in footings can result from settlement, soil movement, or exposure to moisture. Epoxy injection and proper drainage installation are common repair strategies.

Signs of foundation issues may include cracks in walls or floors, uneven or sloping floors, doors or windows that stick or don’t close properly, gaps between walls and ceilings, and visible sinking or shifting of the foundation. If you notice any of these signs, it’s important to have your foundation inspected by professionals to assess the extent of the damage and determine the appropriate repair solutions.

Sistering involves reinforcing damaged joists with additional lumber. It is used to strengthen sagging or damaged joists and prevent further structural issues.

Waterproofing coatings or membranes can be applied to foundation walls to create a barrier against water penetration and prevent moisture-related issues.

Yes, reinforcement methods such as steel plates or carbon fiber strips can strengthen cracked or damaged beams, avoiding the need for full replacement.

One effective method to prevent foundation damage is by installing a comprehensive crawl space drainage system, consisting of both a sump pump and French drains. This combined system helps to manage excess moisture by collecting water from the crawl space and directing it away from the foundation. The sump pump efficiently removes water that accumulates in the crawl space, while French drains help to channel water away from the foundation, preventing it from seeping into the soil around the perimeter. By controlling moisture levels, this drainage system helps to maintain the stability and integrity of the foundation, reducing the risk of damage over time.
