Structural Home Repair

When moisture finds its way into your crawl space or basement, it quietly weakens the wood that supports your floors and home. Over time, that moisture can lead to wood rot, mold, sagging floors, and structural instability.

As a structural repair contractor serving the Carolinas for nearly 40 years, Moisture Loc identifies vulnerable areas in your home, eliminates the moisture causing them, and prescribes a solution for long-term stability and peace of mind.

  • Protect the inside of your home from rot and decay
  • Preserve floor strength and load-bearing capacity
  • Keep wood dry and away from moisture

Keep your home standing strong.

Sagging or Uneven Floors? Start Here

Uneven floors are one of the first things homeowners notice when they have structural instability. It’s also one of the symptoms that sends most people looking for help. A “bouncy” floor or one that slopes toward one corner is not only unnerving, but is also telling you the wood underneath has been compromised. And that’s usually due to moisture.

Sagging floor repair can go a lot of ways. The remedy could range from adding some extra support to replacing joists and beams altogether. It depends on how long the problem has existed and how weak the floor is. For more details about dealing with uneven floors, read How to Hire the Right Structural Repair Contractor.

Common Signs of Structural Issues:

  • Uneven or sagging floors
  • Cracks in drywall, doors, or window frames
  • Musty odors near floors
  • Staining on ceilings or flooring
  • Excess condensation or humidity indoors
  • Pest or termite activity

Moisture in your home is a formidable opponent, and one that won’t quit. The only way to protect your home’s structure is to eliminate the moisture that's undermining it and fix the damage. Moisture Loc’s team can do both.

Replaced Floor Joists

The Importance of Floor Joists

Think about everything in your home. Heavy furniture. Appliances. Even people. Floor joists are meant to support it all, day after day. It’s a critical function that requires quality wood and precise engineering. But even the best wood and plans have their limits, especially when moisture comes into play.

Because wood joists are hidden below your floors, damage often goes unnoticed until it’s advanced. By the time floors start to sag or cracks appear in your living areas, the wood below your home has already been weakened.

As with all structural and foundation issues with your home, it's never a good idea to take a wait-and-see approach. Wood doesn’t get stronger on its own. The best recourse is to call in professionals to survey the damage and prescribe a solution.

Structural Repair FAQs

Can crawl space moisture cause structural damage?

Without a doubt. A damp crawl space keeps the wood above it wet enough that it eventually starts to rot. In Charlotte, it’s damp A LOT, so the problem compounds quickly. Before you know it, joists and beams weaken, and the floors resting on them start to sag. The damage builds out of sight, which is why so many homeowners don’t catch it until a floor is already sagging. At that point, action has to be taken.

Why is moisture control a key component of every structural repair?

Replacing rotted wood without addressing the moisture that caused it just starts the cycle all over again, because the new wood will eventually fail the same way the old wood did. At Moisture Loc, we treat the two as one job. We repair the structure and stop the water source at the same time, whether that entails installing new drainage or doing a full crawl space encapsulation

Do I need a foundation repair company or a structural repair contractor?

If the problem is settling concrete, cracked foundation walls, or a moving slab, that’s foundation work. If it’s more wood-related, like rotting beams and sagging floors, that’s structural repair. Plenty of homes need both looked at, which is okay because we do both. A free inspection will help you better understand what’s happening under your home.

How much does structural repair cost?

It depends on how much damage has already been done. We don’t put a number on it over the phone. We need to survey the situation to determine the cause and cure. A free inspection will let you know what you’re dealing with. Any worthwhile structural repair contractor should provide one.

What does your warranty cover?

We always stand behind the work we do and pull the permits some contractors skip. We believe in doing things once and doing them right. The exact terms of our warranties depend on the repair, so we put the warranty in writing. You can review our warranties before you decide. Before any work starts, we inspect the crawl space and the wood itself and show you what we find. We explain the moisture source driving it and give you a written scope, so you know what we’re fixing, why, and what the warranty covers.

After purchasing my home, I started noticing cracks in the drywall, just a few months later. After finding out the house had structural issues, I interviewed several companies and decided to go with moisture lock. If your dealing with structural issues, I highly recommend Moisture lock for their expertise and customer service. Carlos, James and Scott were excellent. I am very pleased with my experience and the work they did to my home.

I have nothing but good things to say about Moisture Loc. I was referred to them by a friend/neighbor, and they did not disappoint. Carlos was thorough in his initial inspection and project recommendations. There were no surprises. I felt like Carlos was honest when he gave us a quote for the work, and that was very important to me. James came with his crew to actually perform the work, and he was equally as outstanding. The work was completely efficiently and properly, and all projects passed Mecklenburg County inspection the first time around. I couldn't be more pleased and highly recommend this company!

These guys did a great job! We had a moisture issue under the house which was messing up our hardwood floors. I had 2 other companies out and then spoke with my neighbor, who is a contractor. He highly recommended Moisture Loc. They didn't try and sell me on things that were not needed and came in less than the other 2 companies. Their work crew was on time and respectful and pleasant. The job is complete and I'm impressed. Highly recommend!

Got 4 local quotes for encapsulating the crawl space of our home. This was a no-brainer, Moisture Loc was heads and tails above all others. Dan Richert was extremely professional, clear and to the point, no up sale, and answered all questions. Everyone involved including Rich Goldman and Brandon Cook were also extremely professional, knowledgeable, and very responsive. Everything was on time. And thanks Ryan (office person) for being there and answering the phone! (seems to be a lost art these days). Highly recommend these folks!

I am a realtor working on behalf of my buyer client to source quotes for repairs. Carlos has been extremely responsive and knowledgeable about his scope of work. I appreciate his honesty in not trying to upsell me on a sump pump because I recieved quotes from multiple crawlspace companies and called to inquire further about this. He was transparent from the beginning and explained why it was not necessary for this particular property, even before I had the chance to ask him. Thank you for your efforts to earn my business. I appreciate you putting the customers needs before your own pocket and look forward to doing continued business with you!

Had a great experience with Moisture Lock. They installed Helical Piers and re-encapsulated my crawlspace. Jerry was an absolute powerhouse for installing the piers. His knowledge and skills are off the chart. The crawlspace work was great as well - Moisture Lock came in a fixed a botched job that was done by Carolina Crawlspace Pros who are now out of business. Everything is in good order now and these guys did a really great job.
