Crawlspace Repaired with SmartJacks in Middleton Idaho Crawlspace Repaired with SmartJacks in Middleton Idaho

You can hardly tell this is the same crawlspace with the SmartJacks installed! We have been installing SmartJacks all over Idaho such as Bellevue, Blackfoot, Bloomington, Boise, Buhl, Burley, Caldwell, Cascade, Challis, Donnelly, Eagle, Emmett, Garden City, Idaho Falls, Kuna, Lewiston, McCall, Post Falls, Sandpoint, Stanley, and Twin Falls. As you can see we are very experienced at installing SmartJacks. 

The SmartJack™ Crawl Space Stabilizer is an adjustable supplemental support system used for sagging crawl spaces.

It not only provides supplemental support to your failing structure -- it can also often lift failing floor joists or beams, restoring them to their original position.

This crawl space support system is unique in that it's made with strong, corrosion-resistant, galvanized steel. Because your system will not develop rust, it will remain adjustable for years, should you need to perform future adjustments.

This homeowner had a vapor barrier that was not even attached, failing to cover the foundation and foundation walls. This attachment left several pockets of air under the barrier, allowing moisture from the ground to collect. This amount of moisture makes this storage space unusable and can start to cause damage to the household over time. The solution to the problem was to install CleanSpace throughout. We tacked it down so it was secure and covering the foundation walls this time. Now this homeowner will no longer have to worry about moisture collecting in an unwanted area.

We installed power braces to stabilize the walls.

All crawl space encapsulation systems we install include a written 25-year warranty! Get a FREE crawl space repair consultation today!

How Long will CleanSpace Last?

John in Coeur D Alene has a home up in near Huetter on the Snake River. Every few years he checks out his crawlspace just to make sure it’s in good shape, and every year the thin black 6 mil liner is hanging down in areas and serving no purpose. John has replaced the liner 5 times in the last 15 years! “I keep up on every area of my house because one day I plan to sale it” John said.

He started to look for a vapor barrier that would last longer and came with a great warranty. That’s when John found CleanSpace on our website! He gave us a call and we sent Jeff Smith one of our System Design Specialist out to meet with John. Jeff explained how CleanSpace could have such a long warranty. CleanSpace is a super durable: 20mil thick, 7-layer polyethylene composition, with polyester cord reinforcement. In other words…it was exactly what John was looking for.

Just a few weeks later the new liner was installed under John’s house, his crawlspace had never looked so great! John crawled around and inspected the work. He was amazed! “ I am able to use the space for storage now and not worry about ripping the liner, its great! “ John said when we followed up with him a few weeks later. He had even recommend Clean Space to friends and family in Boise, Lewiston, PostFalls and Mascow! 

Potato Cellar in Idaho Falls

Eric and Kim own an old farm house in the small town of Grant, right outside Idaho Falls. In the back yard they have a very large potato cellar. At first they used the cellar as storage but Kim wanted to use the large space for much more.

She wanted to turn it into an art studio/play room for her kids.  She knew it would take a lot more then just cleaning up the space and laying down carpet. She wanted it done right, she knew she would be living in this house for a very long time and he just wanted to take advantage of all the space she could. She talked with Eric and they started to look for a company that specialized in finishing basements.  One thing they had to be sure of was that they needed to make sure the space was waterproofed, being surrounding on almost all sides by soil the ground water could become their biggest issue.That’s when they called Foundation Support Works. We have all the right tools, products and knowledge to take care of all their needs and wants on this project.

By the time we had finished, you never would have guessed you were standing in an old potato cellar.  Not only that but we made the room a lot safer and less moist. Eric and Kim couldn’t have been any happier with the job.  If you have an old cellar or basement that you would like to use as living space please call us we service all of Idaho!

Work Requests From Lewiston, ID
Project Location: Lewiston, ID
We're concerned about our home's foundation and other structural issues. We've noticed cracks in some walls, some foundation cracks in the garage, and sloping issues for some floors. Some of these issues (such as sloping) were here when we bought our house 6 years ago, but others seem to be newer or recurring. We also sometimes hear pops in the walls. Our house (and much of our neighborhood) is built on a hillside.

I am a Real Estate Broker/Investor. I am interested in making an offer on this house but can see that it has some pretty substantial foundation issues. I would like a bid for the work so that I know what I can offer on the home and still make it all work. I would, of course, use your company if I successfully purchase the home. Thank you
